NAME
hg - Mercurial source code management system
SYNOPSIS
hg command [option]... [argument]...

value
repository path
either the pathname of a local repository or the URI of a remote repository.
OPTIONS
-R, --repository
repository root directory or name of overlay bundle file
--cwd change working directory
-y, --noninteractive
do not prompt, automatically pick the first choice for all prompts
-q, --quiet
suppress output
-v, --verbose
enable additional output
--config
set/override config option (use 'section.name=value')
--debug
enable debugging output
--debugger
start debugger
--encoding
set the charset encoding (default: ascii)
--encodingmode
set the charset encoding mode (default: strict)
--traceback
always print a traceback on exception
--time time how long the command takes
--profile
print command execution profile
--version
output version information and exit
-h, --help
display help and exit
COMMANDS
add
hg add [OPTION]... [FILE]...
Schedule files to be version controlled and added to the repository.
The files will be added to the repository at the next commit. To undo an add before that, see hg forget.
If no names are given, add all files to the repository.
An example showing how new (unknown) files are added automatically by hg add:
$ ls
foo.c
$ hg status
? foo.c
$ hg add
adding foo.c
$ hg status
A foo.c
Returns 0 if all files are successfully added.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
-n, --dry-run
do not perform actions, just print output
addremove
hg addremove [OPTION]... [FILE]...
Add all new files and remove all missing files from the repository.
New files are ignored if they match any of the patterns in .hgignore. As with add, these changes take effect at the next commit.
Use the -s/--similarity option to detect renamed files. With a parameter greater than 0, this compares every removed file with every added
file and records those similar enough as renames. This option takes a percentage between 0 (disabled) and 100 (files must be identical) as
its parameter. Detecting renamed files this way can be expensive. After using this option, hg status -C can be used to check which files
were identified as moved or renamed. If this option is not specified, only renames of identical files are detected.
Returns 0 if all files are successfully added.
Options:
-s, --similarity
guess renamed files by similarity (0<=s<=100)
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
annotate
hg annotate [-r REV] [-f] [-a] [-u] [-d] [-n] [-c] [-l] FILE...
List changes in files, showing the revision id responsible for each line
This command is useful for discovering when a change was made and by whom.
Without the -a/--text option, annotate will avoid processing files it detects as binary. With -a, annotate will annotate the file anyway,
although the results will probably be neither useful nor desirable.
Returns 0 on success.
Options:
-r, --rev
annotate the specified revision
--follow
follow copies/renames and list the filename (DEPRECATED)
--no-follow
don't follow copies and renames
-a, --text
treat all files as text
-u, --user
list the author (long with -v)
-f, --file
list the filename
-d, --date
list the date (short with -q)
-n, --number
list the revision number (default)
-c, --changeset
list the changeset
-l, --line-number
show line number at the first appearance
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
aliases: blame
archive
hg archive [OPTION]... DEST
By default, the revision used is the parent of the working directory; use -r/--rev to specify a different revision.
The archive type is automatically detected based on file extension (or override using -t/--type).
Examples:
o create a zip file containing the 1.0 release:
hg archive -r 1.0 project-1.0.zip
o create a tarball excluding .hg files:
hg archive project.tar.gz -X ".hg*"
Valid types are:
files
a directory full of files (default)
tar
tar archive, uncompressed
tbz2
tar archive, compressed using bzip2
tgz
tar archive, compressed using gzip
uzip
zip archive, uncompressed
zip
zip archive, compressed using deflate
The exact name of the destination archive or directory is given using a format string; see hg help export for details.
Each member added to an archive file has a directory prefix prepended. Use -p/--prefix to specify a format string for the prefix. The
default is the basename of the archive, with suffixes removed.
Returns 0 on success.
Options:
--no-decode
do not pass files through decoders
-p, --prefix
directory prefix for files in archive
-r, --rev
revision to distribute
-t, --type
type of distribution to create
-S, --subrepos
recurse into subrepositories
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
backout
hg backout [OPTION]... [-r] REV
Prepare a new changeset with the effect of REV undone in the current working directory.
If REV is the parent of the working directory, then this new changeset is committed automatically. Otherwise, hg needs to merge the changes
and the merged result is left uncommitted.
Note backout cannot be used to fix either an unwanted or incorrect merge.
By default, the pending changeset will have one parent, maintaining a linear history. With --merge, the pending changeset will instead have
two parents: the old parent of the working directory and a new child of REV that simply undoes REV.
Before version 1.7, the behavior without --merge was equivalent to specifying --merge followed by hg update --clean . to cancel the merge
and leave the child of REV as a head to be merged separately.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
--merge
merge with old dirstate parent after backout
--parent
parent to choose when backing out merge (DEPRECATED)
-r, --rev
revision to backout
-t, --tool
specify merge tool
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
bisect
hg bisect [-gbsr] [-U] [-c CMD] [REV]
This command helps to find changesets which introduce problems. To use, mark the earliest changeset you know exhibits the problem as bad,
then mark the latest changeset which is free from the problem as good. Bisect will update your working directory to a revision for testing
(unless the -U/--noupdate option is specified). Once you have performed tests, mark the working directory as good or bad, and bisect will
either update to another candidate changeset or announce that it has found the bad revision.
As a shortcut, you can also use the revision argument to mark a revision as good or bad without checking it out first.
If you supply a command, it will be used for automatic bisection. Its exit status will be used to mark revisions as good or bad: status 0
means good, 125 means to skip the revision, 127 (command not found) will abort the bisection, and any other non-zero exit status means the
revision is bad.
Some examples:
o start a bisection with known bad revision 12, and good revision 34:
hg bisect --bad 34
hg bisect --good 12
o advance the current bisection by marking current revision as good or bad:
hg bisect --good
hg bisect --bad
o mark the current revision, or a known revision, to be skipped (eg. if that revision is not usable because of another issue):
hg bisect --skip
hg bisect --skip 23
o forget the current bisection:
hg bisect --reset
o use 'make && make tests' to automatically find the first broken revision:
hg bisect --reset
hg bisect --bad 34
hg bisect --good 12
hg bisect --command 'make && make tests'
o see all changesets whose states are already known in the current bisection:
hg log -r "bisect(pruned)"
o see all changesets that took part in the current bisection:
hg log -r "bisect(range)"
o with the graphlog extension, you can even get a nice graph:
hg log --graph -r "bisect(range)"
See hg help revsets for more about the bisect() keyword.
Returns 0 on success.
Options:
-r, --reset
reset bisect state
-g, --good
mark changeset good
-b, --bad
mark changeset bad
-s, --skip
skip testing changeset
-e, --extend
extend the bisect range
-c, --command
use command to check changeset state
-U, --noupdate
do not update to target
bookmarks
hg bookmarks [-f] [-d] [-i] [-m NAME] [-r REV] [NAME]
Bookmarks are pointers to certain commits that move when committing. Bookmarks are local. They can be renamed, copied and deleted. It is
possible to use hg merge NAME to merge from a given bookmark, and hg update NAME to update to a given bookmark.
You can use hg bookmark NAME to set a bookmark on the working directory's parent revision with the given name. If you specify a revision
using -r REV (where REV may be an existing bookmark), the bookmark is assigned to that revision.
Bookmarks can be pushed and pulled between repositories (see hg help push and hg help pull). This requires both the local and remote repos-
itories to support bookmarks. For versions prior to 1.8, this means the bookmarks extension must be enabled.
With -i/--inactive, the new bookmark will not be made the active bookmark. If -r/--rev is given, the new bookmark will not be made active
even if -i/--inactive is not given. If no NAME is given, the current active bookmark will be marked inactive.
Options:
-f, --force
force
-r, --rev
revision
-d, --delete
delete a given bookmark
-m, --rename
rename a given bookmark
-i, --inactive
mark a bookmark inactive
branch
hg branch [-fC] [NAME]
Note Branch names are permanent and global. Use hg bookmark to create a light-weight bookmark instead. See hg help glossary for more
information about named branches and bookmarks.
With no argument, show the current branch name. With one argument, set the working directory branch name (the branch will not exist in the
repository until the next commit). Standard practice recommends that primary development take place on the 'default' branch.
Unless -f/--force is specified, branch will not let you set a branch name that already exists, even if it's inactive.
Use -C/--clean to reset the working directory branch to that of the parent of the working directory, negating a previous branch change.
Use the command hg update to switch to an existing branch. Use hg commit --close-branch to mark this branch as closed.
Returns 0 on success.
Options:
-f, --force
set branch name even if it shadows an existing branch
-C, --clean
reset branch name to parent branch name
branches
hg branches [-ac]
List the repository's named branches, indicating which ones are inactive. If -c/--closed is specified, also list branches which have been
marked closed (see hg commit --close-branch).
If -a/--active is specified, only show active branches. A branch is considered active if it contains repository heads.
Use the command hg update to switch to an existing branch.
Returns 0.
Options:
-a, --active
show only branches that have unmerged heads
-c, --closed
show normal and closed branches
bundle
hg bundle [-f] [-t TYPE] [-a] [-r REV]... [--base REV]... FILE [DEST]
Generate a compressed changegroup file collecting changesets not known to be in another repository.
If you omit the destination repository, then hg assumes the destination will have all the nodes you specify with --base parameters. To cre-
ate a bundle containing all changesets, use -a/--all (or --base null).
You can change compression method with the -t/--type option. The available compression methods are: none, bzip2, and gzip (by default,
bundles are compressed using bzip2).
The bundle file can then be transferred using conventional means and applied to another repository with the unbundle or pull command. This
is useful when direct push and pull are not available or when exporting an entire repository is undesirable.
Applying bundles preserves all changeset contents including permissions, copy/rename information, and revision history.
Returns 0 on success, 1 if no changes found.
Options:
-f, --force
run even when the destination is unrelated
-r, --rev
a changeset intended to be added to the destination
-b, --branch
a specific branch you would like to bundle
--base a base changeset assumed to be available at the destination
-a, --all
bundle all changesets in the repository
-t, --type
bundle compression type to use (default: bzip2)
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
cat
hg cat [OPTION]... FILE...
Print the specified files as they were at the given revision. If no revision is given, the parent of the working directory is used, or tip
if no revision is checked out.
Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are the same as for the
export command, with the following additions:
%s
basename of file being printed
%d
dirname of file being printed, or '.' if in repository root
%p
root-relative path name of file being printed
Returns 0 on success.
Options:
-o, --output
print output to file with formatted name
-r, --rev
print the given revision
--decode
apply any matching decode filter
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
clone
hg clone [OPTION]... SOURCE [DEST]
Create a copy of an existing repository in a new directory.
If no destination directory name is specified, it defaults to the basename of the source.
The location of the source is added to the new repository's .hg/hgrc file, as the default to be used for future pulls.
Only local paths and ssh:// URLs are supported as destinations. For ssh:// destinations, no working directory or .hg/hgrc will be created
on the remote side.
To pull only a subset of changesets, specify one or more revisions identifiers with -r/--rev or branches with -b/--branch. The resulting
clone will contain only the specified changesets and their ancestors. These options (or 'clone src#rev dest') imply --pull, even for local
source repositories. Note that specifying a tag will include the tagged changeset but not the changeset containing the tag.
To check out a particular version, use -u/--update, or -U/--noupdate to create a clone with no working directory.
For efficiency, hardlinks are used for cloning whenever the source and destination are on the same filesystem (note this applies only to
the repository data, not to the working directory). Some filesystems, such as AFS, implement hardlinking incorrectly, but do not report
errors. In these cases, use the --pull option to avoid hardlinking.
In some cases, you can clone repositories and the working directory using full hardlinks with
$ cp -al REPO REPOCLONE
This is the fastest way to clone, but it is not always safe. The operation is not atomic (making sure REPO is not modified during the oper-
ation is up to you) and you have to make sure your editor breaks hardlinks (Emacs and most Linux Kernel tools do so). Also, this is not
compatible with certain extensions that place their metadata under the .hg directory, such as mq.
Mercurial will update the working directory to the first applicable revision from this list:
a. null if -U or the source repository has no changesets
b. if -u . and the source repository is local, the first parent of the source repository's working directory
c. the changeset specified with -u (if a branch name, this means the latest head of that branch)
d. the changeset specified with -r
e. the tipmost head specified with -b
f. the tipmost head specified with the url#branch source syntax
g. the tipmost head of the default branch
h. tip
Examples:
o clone a remote repository to a new directory named hg/:
hg clone http://selenic.com/hg
o create a lightweight local clone:
hg clone project/ project-feature/
o clone from an absolute path on an ssh server (note double-slash):
hg clone ssh://user@server//home/projects/alpha/
o do a high-speed clone over a LAN while checking out a specified version:
hg clone --uncompressed http://server/repo -u 1.5
o create a repository without changesets after a particular revision:
hg clone -r 04e544 experimental/ good/
o clone (and track) a particular named branch:
hg clone http://selenic.com/hg#stable
See hg help urls for details on specifying URLs.
Returns 0 on success.
Options:
-U, --noupdate
the clone will include an empty working copy (only a repository)
-u, --updaterev
revision, tag or branch to check out
-r, --rev
include the specified changeset
-b, --branch
clone only the specified branch
--pull use pull protocol to copy metadata
--uncompressed
use uncompressed transfer (fast over LAN)
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
commit
hg commit [OPTION]... [FILE]...
Commit changes to the given files into the repository. Unlike a centralized SCM, this operation is a local operation. See hg push for a way
to actively distribute your changes.
If a list of files is omitted, all changes reported by hg status will be committed.
If you are committing the result of a merge, do not provide any filenames or -I/-X filters.
If no commit message is specified, Mercurial starts your configured editor where you can enter a message. In case your commit fails, you
will find a backup of your message in .hg/last-message.txt.
The --amend flag can be used to amend the parent of the working directory with a new commit that contains the changes in the parent in
addition to those currently reported by hg status, if there are any. The old commit is stored in a backup bundle in .hg/strip-backup (see
hg help bundle and hg help unbundle on how to restore it).
Message, user and date are taken from the amended commit unless specified. When a message isn't specified on the command line, the editor
will open with the message of the amended commit.
It is not possible to amend public changesets (see hg help phases) or changesets that have children.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if nothing changed.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch as closed, hiding it from the branch list
--amend
amend the parent of the working dir
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
-S, --subrepos
recurse into subrepositories
aliases: ci
copy
hg copy [OPTION]... [SOURCE]... DEST
Mark dest as having copies of source files. If dest is a directory, copies are put in that directory. If dest is a file, the source must be
a single file.
By default, this command copies the contents of files as they exist in the working directory. If invoked with -A/--after, the operation is
recorded, but no copying is performed.
This command takes effect with the next commit. To undo a copy before that, see hg revert.
Returns 0 on success, 1 if errors are encountered.
Options:
-A, --after
record a copy that has already occurred
-f, --force
forcibly copy over an existing managed file
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
aliases: cp
diff
hg diff [OPTION]... ([-c REV] | [-r REV1 [-r REV2]]) [FILE]...
Show differences between revisions for the specified files.
Differences between files are shown using the unified diff format.
Note diff may generate unexpected results for merges, as it will default to comparing against the working directory's first parent
changeset if no revisions are specified.
When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision
is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent.
Alternatively you can specify -c/--change with a revision to see the changes in that changeset relative to its first parent.
Without the -a/--text option, diff will avoid generating diffs of files it detects as binary. With -a, diff will generate a diff anyway,
probably with undesirable results.
Use the -g/--git option to generate diffs in the git extended diff format. For more information, read hg help diffs.
Examples:
o compare a file in the current working directory to its parent:
hg diff foo.c
o compare two historical versions of a directory, with rename info:
hg diff --git -r 1.0:1.2 lib/
o get change stats relative to the last change on some date:
hg diff --stat -r "date('may 2')"
o diff all newly-added files that contain a keyword:
hg diff "set:added() and grep(GNU)"
o compare a revision and its parents:
hg diff -c 9353 # compare against first parent
hg diff -r 9353^:9353 # same using revset syntax
hg diff -r 9353^2:9353 # compare against the second parent
Returns 0 on success.
Options:
-r, --rev
revision
-c, --change
change made by revision
-a, --text
treat all files as text
-g, --git
use git extended diff format
--nodates
omit dates from diff headers
-p, --show-function
show which function each change is in
--reverse
produce a diff that undoes the changes
-w, --ignore-all-space
ignore white space when comparing lines
-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-U, --unified
number of lines of context to show
--stat output diffstat-style summary of changes
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
export
hg export [OPTION]... [-o OUTFILESPEC] REV...
Print the changeset header and diffs for one or more revisions.
The information shown in the changeset header is: author, date, branch name (if non-default), changeset hash, parent(s) and commit comment.
Note export may generate unexpected diff output for merge changesets, as it will compare the merge changeset against its first parent
only.
Output may be to a file, in which case the name of the file is given using a format string. The formatting rules are as follows:
%%
literal "%" character
%H
changeset hash (40 hexadecimal digits)
%N
number of patches being generated
%R
changeset revision number
%b
basename of the exporting repository
%h
short-form changeset hash (12 hexadecimal digits)
%m
first line of the commit message (only alphanumeric characters)
%n
zero-padded sequence number, starting at 1
%r
zero-padded changeset revision number
Without the -a/--text option, export will avoid generating diffs of files it detects as binary. With -a, export will generate a diff any-
way, probably with undesirable results.
Use the -g/--git option to generate diffs in the git extended diff format. See hg help diffs for more information.
With the --switch-parent option, the diff will be against the second parent. It can be useful to review a merge.
Examples:
o use export and import to transplant a bugfix to the current branch:
hg export -r 9353 | hg import -
o export all the changesets between two revisions to a file with rename information:
hg export --git -r 123:150 > changes.txt
o split outgoing changes into a series of patches with descriptive names:
hg export -r "outgoing()" -o "%n-%m.patch"
Returns 0 on success.
Options:
-o, --output
print output to file with formatted name
--switch-parent
diff against the second parent
-r, --rev
revisions to export
-a, --text
treat all files as text
-g, --git
use git extended diff format
--nodates
omit dates from diff headers
forget
hg forget [OPTION]... FILE...
Mark the specified files so they will no longer be tracked after the next commit.
This only removes files from the current branch, not from the entire project history, and it does not delete them from the working direc-
tory.
To undo a forget before the next commit, see hg add.
Examples:
o forget newly-added binary files:
hg forget "set:added() and binary()"
o forget files that would be excluded by .hgignore:
hg forget "set:hgignore()"
Returns 0 on success.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
graft
hg graft [OPTION]... REVISION...
This command uses Mercurial's merge logic to copy individual changes from other branches without merging branches in the history graph.
This is sometimes known as 'backporting' or 'cherry-picking'. By default, graft will copy user, date, and description from the source
changesets.
Changesets that are ancestors of the current revision, that have already been grafted, or that are merges will be skipped.
If a graft merge results in conflicts, the graft process is interrupted so that the current merge can be manually resolved. Once all con-
flicts are addressed, the graft process can be continued with the -c/--continue option.
Note The -c/--continue option does not reapply earlier options.
Examples:
o copy a single change to the stable branch and edit its description:
hg update stable
hg graft --edit 9393
o graft a range of changesets with one exception, updating dates:
hg graft -D "2085::2093 and not 2091"
o continue a graft after resolving conflicts:
hg graft -c
o show the source of a grafted changeset:
hg log --debug -r tip
Returns 0 on successful completion.
Options:
-c, --continue
resume interrupted graft
-e, --edit
invoke editor on commit messages
-D, --currentdate
record the current date as commit date
-U, --currentuser
record the current user as committer
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
-t, --tool
specify merge tool
-n, --dry-run
do not perform actions, just print output
grep
hg grep [OPTION]... PATTERN [FILE]...
Search revisions of files for a regular expression.
This command behaves differently than Unix grep. It only accepts Python/Perl regexps. It searches repository history, not the working
directory. It always prints the revision number in which a match appears.
By default, grep only prints output for the first revision of a file in which it finds a match. To get it to print every revision that con-
tains a change in match status ("-" for a match that becomes a non-match, or "+" for a non-match that becomes a match), use the --all flag.
Returns 0 if a match is found, 1 otherwise.
Options:
-0, --print0
end fields with NUL
--all print all revisions that match
-a, --text
treat all files as text
-f, --follow
follow changeset history, or file history across copies and renames
-i, --ignore-case
ignore case when matching
-l, --files-with-matches
print only filenames and revisions that match
-n, --line-number
print matching line numbers
-r, --rev
only search files changed within revision range
-u, --user
list the author (long with -v)
-d, --date
list the date (short with -q)
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
heads
hg heads [-ac] [-r STARTREV] [REV]...
With no arguments, show all repository branch heads.
Repository "heads" are changesets with no child changesets. They are where development generally takes place and are the usual targets for
update and merge operations. Branch heads are changesets that have no child changeset on the same branch.
If one or more REVs are given, only branch heads on the branches associated with the specified changesets are shown. This means that you
can use hg heads foo to see the heads on a branch named foo.
If -c/--closed is specified, also show branch heads marked closed (see hg commit --close-branch).
If STARTREV is specified, only those heads that are descendants of STARTREV will be displayed.
If -t/--topo is specified, named branch mechanics will be ignored and only changesets without children will be shown.
Returns 0 if matching heads are found, 1 if not.
Options:
-r, --rev
show only heads which are descendants of STARTREV
-t, --topo
show topological heads only
-a, --active
show active branchheads only (DEPRECATED)
-c, --closed
show normal and closed branch heads
--style
display using template map file
--template
display with template
help
hg help [-ec] [TOPIC]
With no arguments, print a list of commands with short help messages.
Given a topic, extension, or command name, print help for that topic.
Returns 0 if successful.
Options:
-e, --extension
show only help for extensions
-c, --command
show only help for commands
identify
hg identify [-nibtB] [-r REV] [SOURCE]
Print a summary identifying the repository state at REV using one or two parent hash identifiers, followed by a "+" if the working direc-
tory has uncommitted changes, the branch name (if not default), a list of tags, and a list of bookmarks.
When REV is not given, print a summary of the current state of the repository.
Specifying a path to a repository root or Mercurial bundle will cause lookup to operate on that repository/bundle.
Examples:
o generate a build identifier for the working directory:
hg id --id > build-id.dat
o find the revision corresponding to a tag:
hg id -n -r 1.3
o check the most recent revision of a remote repository:
hg id -r tip http://selenic.com/hg/
Returns 0 if successful.
Options:
-r, --rev
identify the specified revision
-n, --num
show local revision number
-i, --id
show global revision id
-b, --branch
show branch
-t, --tags
show tags
-B, --bookmarks
show bookmarks
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
aliases: id
import
hg import [OPTION]... PATCH...
Import a list of patches and commit them individually (unless --no-commit is specified).
If there are outstanding changes in the working directory, import will abort unless given the -f/--force flag.
You can import a patch straight from a mail message. Even patches as attachments work (to use the body part, it must have type text/plain
or text/x-patch). From and Subject headers of email message are used as default committer and commit message. All text/plain body parts
before first diff are added to commit message.
If the imported patch was generated by hg export, user and description from patch override values from message headers and body. Values
given on command line with -m/--message and -u/--user override these.
If --exact is specified, import will set the working directory to the parent of each patch before applying it, and will abort if the
resulting changeset has a different ID than the one recorded in the patch. This may happen due to character set problems or other deficien-
cies in the text patch format.
Use --bypass to apply and commit patches directly to the repository, not touching the working directory. Without --exact, patches will be
applied on top of the working directory parent revision.
With -s/--similarity, hg will attempt to discover renames and copies in the patch in the same way as hg addremove.
To read a patch from standard input, use "-" as the patch name. If a URL is specified, the patch will be downloaded from it. See hg help
dates for a list of formats valid for -d/--date.
Examples:
o import a traditional patch from a website and detect renames:
hg import -s 80 http://example.com/bugfix.patch
o import a changeset from an hgweb server:
hg import http://www.selenic.com/hg/rev/5ca8c111e9aa
o import all the patches in an Unix-style mbox:
hg import incoming-patches.mbox
o attempt to exactly restore an exported changeset (not always possible):
hg import --exact proposed-fix.patch
Returns 0 on success.
Options:
-p, --strip
directory strip option for patch. This has the same meaning as the corresponding patch option (default: 1)
-b, --base
base path (DEPRECATED)
-e, --edit
invoke editor on commit messages
-f, --force
skip check for outstanding uncommitted changes
--no-commit
don't commit, just update the working directory
--bypass
apply patch without touching the working directory
--exact
apply patch to the nodes from which it was generated
--import-branch
use any branch information in patch (implied by --exact)
-m, --message
use text as commit message
-l, --logfile
read commit message from file
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
-s, --similarity
guess renamed files by similarity (0<=s<=100)
aliases: patch
incoming
hg incoming [-p] [-n] [-M] [-f] [-r REV]... [--bundle FILENAME] [SOURCE]
Show new changesets found in the specified path/URL or the default pull location. These are the changesets that would have been pulled if a
pull at the time you issued this command.
For remote repository, using --bundle avoids downloading the changesets twice if the incoming is followed by a pull.
See pull for valid source format details.
Returns 0 if there are incoming changes, 1 otherwise.
Options:
-f, --force
run even if remote repository is unrelated
-n, --newest-first
show newest record first
--bundle
file to store the bundles into
-r, --rev
a remote changeset intended to be added
-B, --bookmarks
compare bookmarks
-b, --branch
a specific branch you would like to pull
-p, --patch
show patch
-g, --git
use git extended diff format
-l, --limit
limit number of changes displayed
-M, --no-merges
do not show merges
--stat output diffstat-style summary of changes
--style
display using template map file
--template
display with template
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
-S, --subrepos
recurse into subrepositories
aliases: in
init
hg init [-e CMD] [--remotecmd CMD] [DEST]
Initialize a new repository in the given directory. If the given directory does not exist, it will be created.
If no directory is given, the current directory is used.
It is possible to specify an ssh:// URL as the destination. See hg help urls for more information.
Returns 0 on success.
Options:
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
locate
hg locate [OPTION]... [PATTERN]...
Print files under Mercurial control in the working directory whose names match the given patterns.
By default, this command searches all directories in the working directory. To search just the current directory and its subdirectories,
use "--include .".
If no patterns are given to match, this command prints the names of all files under Mercurial control in the working directory.
If you want to feed the output of this command into the "xargs" command, use the -0 option to both this command and "xargs". This will
avoid the problem of "xargs" treating single filenames that contain whitespace as multiple filenames.
Returns 0 if a match is found, 1 otherwise.
Options:
-r, --rev
search the repository as it is in REV
-0, --print0
end filenames with NUL, for use with xargs
-f, --fullpath
print complete paths from the filesystem root
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
log
hg log [OPTION]... [FILE]
Print the revision history of the specified files or the entire project.
If no revision range is specified, the default is tip:0 unless --follow is set, in which case the working directory parent is used as the
starting revision.
File history is shown without following rename or copy history of files. Use -f/--follow with a filename to follow history across renames
and copies. --follow without a filename will only show ancestors or descendants of the starting revision.
By default this command prints revision number and changeset id, tags, non-trivial parents, user, date and time, and a summary for each
commit. When the -v/--verbose switch is used, the list of changed files and full commit message are shown.
Note log -p/--patch may generate unexpected diff output for merge changesets, as it will only compare the merge changeset against its
first parent. Also, only files different from BOTH parents will appear in files:.
Note for performance reasons, log FILE may omit duplicate changes made on branches and will not show deletions. To see all changes
including duplicates and deletions, use the --removed switch.
Some examples:
o changesets with full descriptions and file lists:
hg log -v
o changesets ancestral to the working directory:
hg log -f
o last 10 commits on the current branch:
hg log -l 10 -b .
o changesets showing all modifications of a file, including removals:
hg log --removed file.c
o all changesets that touch a directory, with diffs, excluding merges:
hg log -Mp lib/
o all revision numbers that match a keyword:
hg log -k bug --template "{rev}
"
o check if a given changeset is included is a tagged release:
hg log -r "a21ccf and ancestor(1.9)"
o find all changesets by some user in a date range:
hg log -k alice -d "may 2008 to jul 2008"
o summary of all changesets after the last tag:
hg log -r "last(tagged())::" --template "{desc|firstline}
"
See hg help dates for a list of formats valid for -d/--date.
See hg help revisions and hg help revsets for more about specifying revisions.
See hg help templates for more about pre-packaged styles and specifying custom templates.
Returns 0 on success.

aliases: history
manifest
hg manifest [-r REV]
Print a list of version controlled files for the given revision. If no revision is given, the first parent of the working directory is
used, or the null revision if no revision is checked out.
With -v, print file permissions, symlink and executable bits. With --debug, print file revision hashes.
If option --all is specified, the list of all files from all revisions is printed. This includes deleted and renamed files.
Returns 0 on success.
Options:
-r, --rev
revision to display
--all list files from all revisions
merge
hg merge [-P] [-f] [[-r] REV]
The current working directory is updated with all changes made in the requested revision since the last common predecessor revision.
Files that changed between either parent are marked as changed for the next commit and a commit must be performed before any further
updates to the repository are allowed. The next commit will have two parents.
--tool can be used to specify the merge tool used for file merges. It overrides the HGMERGE environment variable and your configuration
files. See hg help merge-tools for options.
If no revision is specified, the working directory's parent is a head revision, and the current branch contains exactly one other head, the
other head is merged with by default. Otherwise, an explicit revision with which to merge with must be provided.
hg resolve must be used to resolve unresolved files.
To undo an uncommitted merge, use hg update --clean . which will check out a clean copy of the original merge parent, losing all changes.
Returns 0 on success, 1 if there are unresolved files.
Options:
-f, --force
force a merge with outstanding changes
-r, --rev
revision to merge
-P, --preview
review revisions to merge (no merge is performed)
-t, --tool
specify merge tool
outgoing
hg outgoing [-M] [-p] [-n] [-f] [-r REV]... [DEST]
Show changesets not found in the specified destination repository or the default push location. These are the changesets that would be
pushed if a push was requested.
See pull for details of valid destination formats.
Returns 0 if there are outgoing changes, 1 otherwise.
Options:
-f, --force
run even when the destination is unrelated
-r, --rev
a changeset intended to be included in the destination
-n, --newest-first
show newest record first
-B, --bookmarks
compare bookmarks
-b, --branch
a specific branch you would like to push
-p, --patch
show patch
-g, --git

--insecure
do not verify server certificate (ignoring web.cacerts config)
-S, --subrepos
recurse into subrepositories
aliases: out
parents
hg parents [-r REV] [FILE]
Print the working directory's parent revisions. If a revision is given via -r/--rev, the parent of that revision will be printed. If a
file argument is given, the revision in which the file was last changed (before the working directory revision or the argument to --rev if
given) is printed.
Returns 0 on success.
Options:
-r, --rev
show parents of the specified revision
--style
display using template map file
--template
display with template
paths
hg paths [NAME]
Show definition of symbolic path name NAME. If no name is given, show definition of all available names.
Option -q/--quiet suppresses all output when searching for NAME and shows only the path names when listing all definitions.
Path names are defined in the [paths] section of your configuration file and in /etc/mercurial/hgrc. If run inside a repository, .hg/hgrc
is used, too.
The path names default and default-push have a special meaning. When performing a push or pull operation, they are used as fallbacks if no
location is specified on the command-line. When default-push is set, it will be used for push and default will be used for pull; otherwise
default is used as the fallback for both. When cloning a repository, the clone source is written as default in .hg/hgrc. Note that
default and default-push apply to all inbound (e.g. hg incoming) and outbound (e.g. hg outgoing, hg email and hg bundle) operations.
See hg help urls for more information.
Returns 0 on success.
phase
hg phase [-p|-d|-s] [-f] [-r] REV...
With no argument, show the phase name of specified revisions.
With one of -p/--public, -d/--draft or -s/--secret, change the phase value of the specified revisions.
Unless -f/--force is specified, hg phase won't move changeset from a lower phase to an higher phase. Phases are ordered as follows:
public < draft < secret
Return 0 on success, 1 if no phases were changed or some could not be changed.
Options:
-p, --public
set changeset phase to public
-d, --draft
set changeset phase to draft
-s, --secret
set changeset phase to secret
-f, --force
allow to move boundary backward
-r, --rev
target revision
pull
hg pull [-u] [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [SOURCE]
Pull changes from a remote repository to a local one.
This finds all changes from the repository at the specified path or URL and adds them to a local repository (the current one unless -R is
specified). By default, this does not update the copy of the project in the working directory.
Use hg incoming if you want to see what would have been added by a pull at the time you issued this command. If you then decide to add
those changes to the repository, you should use hg pull -r X where X is the last changeset listed by hg incoming.
If SOURCE is omitted, the 'default' path will be used. See hg help urls for more information.
Returns 0 on success, 1 if an update had unresolved files.
Options:
-u, --update
update to new branch head if changesets were pulled
-f, --force
run even when remote repository is unrelated
-r, --rev
a remote changeset intended to be added
-B, --bookmark
bookmark to pull
-b, --branch
a specific branch you would like to pull
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
push
hg push [-f] [-r REV]... [-e CMD] [--remotecmd CMD] [DEST]
Push changesets from the local repository to the specified destination.
This operation is symmetrical to pull: it is identical to a pull in the destination repository from the current one.
By default, push will not allow creation of new heads at the destination, since multiple heads would make it unclear which head to use. In
this situation, it is recommended to pull and merge before pushing.
Use --new-branch if you want to allow push to create a new named branch that is not present at the destination. This allows you to only
create a new branch without forcing other changes.
Use -f/--force to override the default behavior and push all changesets on all branches.
If -r/--rev is used, the specified revision and all its ancestors will be pushed to the remote repository.
Please see hg help urls for important details about ssh:// URLs. If DESTINATION is omitted, a default path will be used.
Returns 0 if push was successful, 1 if nothing to push.
Options:
-f, --force
force push
-r, --rev
a changeset intended to be included in the destination
-B, --bookmark
bookmark to push
-b, --branch
a specific branch you would like to push
--new-branch
allow pushing a new branch
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
recover
hg recover
Recover from an interrupted commit or pull.
This command tries to fix the repository status after an interrupted operation. It should only be necessary when Mercurial suggests it.
Returns 0 if successful, 1 if nothing to recover or verify fails.
remove
hg remove [OPTION]... FILE...
Schedule the indicated files for removal from the current branch.
This command schedules the files to be removed at the next commit. To undo a remove before that, see hg revert. To undo added files, see
hg forget.
-A/--after can be used to remove only files that have already been deleted, -f/--force can be used to force deletion, and -Af can be used
to remove files from the next revision without deleting them from the working directory.
The following table details the behavior of remove for different file states (columns) and option combinations (rows). The file states are
Added [A], Clean [C], Modified [M] and Missing [!] (as reported by hg status). The actions are Warn, Remove (from branch) and Delete (from
disk):
+-----+---+----+----+---+
| | | | | |
+-----+---+----+----+---+
|none | W | RD | W | R |
+-----+---+----+----+---+
|-f | R | RD | RD | R |
+-----+---+----+----+---+
|-A | W | W | W | R |
+-----+---+----+----+---+
|-Af | R | R | R | R |
+-----+---+----+----+---+
Note that remove never deletes files in Added [A] state from the working directory, not even if option --force is specified.
Returns 0 on success, 1 if any warnings encountered.
Options:
-A, --after
record delete for missing files
-f, --force
remove (and delete) file even if added or modified
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
aliases: rm
rename
hg rename [OPTION]... SOURCE... DEST
Mark dest as copies of sources; mark sources for deletion. If dest is a directory, copies are put in that directory. If dest is a file,
there can only be one source.
By default, this command copies the contents of files as they exist in the working directory. If invoked with -A/--after, the operation is
recorded, but no copying is performed.
This command takes effect at the next commit. To undo a rename before that, see hg revert.
Returns 0 on success, 1 if errors are encountered.
Options:
-A, --after
record a rename that has already occurred
-f, --force
forcibly copy over an existing managed file
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
aliases: move mv
resolve
hg resolve [OPTION]... [FILE]...
Merges with unresolved conflicts are often the result of non-interactive merging using the internal:merge configuration setting, or a com-
mand-line merge tool like diff3. The resolve command is used to manage the files involved in a merge, after hg merge has been run, and
before hg commit is run (i.e. the working directory must have two parents). See hg help merge-tools for information on configuring merge
tools.
The resolve command can be used in the following ways:
o hg resolve [--tool TOOL] FILE...: attempt to re-merge the specified files, discarding any previous merge attempts. Re-merging is not per-
formed for files already marked as resolved. Use --all/-a to select all unresolved files. --tool can be used to specify the merge tool
used for the given files. It overrides the HGMERGE environment variable and your configuration files. Previous file contents are saved
with a .orig suffix.
o hg resolve -m [FILE]: mark a file as having been resolved (e.g. after having manually fixed-up the files). The default is to mark all
unresolved files.
o hg resolve -u [FILE]...: mark a file as unresolved. The default is to mark all resolved files.
o hg resolve -l: list files which had or still have conflicts. In the printed list, U = unresolved and R = resolved.
Note that Mercurial will not let you commit files with unresolved merge conflicts. You must use hg resolve -m ... before you can commit
after a conflicting merge.
Returns 0 on success, 1 if any files fail a resolve attempt.
Options:
-a, --all
select all unresolved files
-l, --list
list state of files needing merge
-m, --mark
mark files as resolved
-u, --unmark
mark files as unresolved
-n, --no-status
hide status prefix
-t, --tool
specify merge tool
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
revert
hg revert [OPTION]... [-r REV] [NAME]...
Note To check out earlier revisions, you should use hg update REV. To cancel a merge (and lose your changes), use hg update --clean ..
With no revision specified, revert the specified files or directories to the contents they had in the parent of the working directory.
This restores the contents of files to an unmodified state and unschedules adds, removes, copies, and renames. If the working directory has
two parents, you must explicitly specify a revision.
Using the -r/--rev or -d/--date options, revert the given files or directories to their states as of a specific revision. Because revert
does not change the working directory parents, this will cause these files to appear modified. This can be helpful to "back out" some or
all of an earlier change. See hg backout for a related method.
Modified files are saved with a .orig suffix before reverting. To disable these backups, use --no-backup.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
-a, --all
revert all changes when no arguments given
-d, --date
tipmost revision matching date
-r, --rev
revert to the specified revision
-C, --no-backup
do not save backup copies of files
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-n, --dry-run
do not perform actions, just print output
rollback
hg rollback
This command should be used with care. There is only one level of rollback, and there is no way to undo a rollback. It will also restore
the dirstate at the time of the last transaction, losing any dirstate changes since that time. This command does not alter the working
directory.
Transactions are used to encapsulate the effects of all commands that create new changesets or propagate existing changesets into a reposi-
tory. For example, the following commands are transactional, and their effects can be rolled back:
o commit
o import
o pull
o push (with this repository as the destination)
o unbundle
To avoid permanent data loss, rollback will refuse to rollback a commit transaction if it isn't checked out. Use --force to override this
protection.
This command is not intended for use on public repositories. Once changes are visible for pull by other users, rolling a transaction back
locally is ineffective (someone else may already have pulled the changes). Furthermore, a race is possible with readers of the repository;
for example an in-progress pull from the repository may fail if a rollback is performed.
Returns 0 on success, 1 if no rollback data is available.
Options:
-n, --dry-run
do not perform actions, just print output
-f, --force
ignore safety measures
root
hg root
Print the root directory of the current repository.
Returns 0 on success.
serve
hg serve [OPTION]...
Start a local HTTP repository browser and pull server. You can use this for ad-hoc sharing and browsing of repositories. It is recommended
to use a real web server to serve a repository for longer periods of time.
Please note that the server does not implement access control. This means that, by default, anybody can read from the server and nobody
can write to it by default. Set the web.allow_push option to * to allow everybody to push to the server. You should use a real web server
if you need to authenticate users.
By default, the server logs accesses to stdout and errors to stderr. Use the -A/--accesslog and -E/--errorlog options to log to files.
To have the server choose a free port number to listen on, specify a port number of 0; in this case, the server will print the port number
it uses.
Returns 0 on success.
Options:
-A, --accesslog
name of access log file to write to
-d, --daemon
run server in background
--daemon-pipefds
used internally by daemon mode
-E, --errorlog
name of error log file to write to
-p, --port
port to listen on (default: 8000)
-a, --address
address to listen on (default: all interfaces)
--prefix
prefix path to serve from (default: server root)
-n, --name
name to show in web pages (default: working directory)
--web-conf
name of the hgweb config file (see "hg help hgweb")
--webdir-conf
name of the hgweb config file (DEPRECATED)
--pid-file
name of file to write process ID to
--stdio
for remote clients
--cmdserver
for remote clients
-t, --templates
web templates to use
--style
template style to use
-6, --ipv6
use IPv6 in addition to IPv4
--certificate
SSL certificate file
showconfig
hg showconfig [-u] [NAME]...
With no arguments, print names and values of all config items.
With one argument of the form section.name, print just the value of that config item.
With multiple arguments, print names and values of all config items with matching section names.
With --debug, the source (filename and line number) is printed for each config item.
Returns 0 on success.
Options:
-u, --untrusted
show untrusted configuration options
aliases: debugconfig
status
hg status [OPTION]... [FILE]...
Show status of files in the repository. If names are given, only files that match are shown. Files that are clean or ignored or the source
of a copy/move operation, are not listed unless -c/--clean, -i/--ignored, -C/--copies or -A/--all are given. Unless options described with
"show only ..." are given, the options -mardu are used.
Option -q/--quiet hides untracked (unknown and ignored) files unless explicitly requested with -u/--unknown or -i/--ignored.
Note status may appear to disagree with diff if permissions have changed or a merge has occurred. The standard diff format does not
report permission changes and diff only reports changes relative to one merge parent.
If one revision is given, it is used as the base revision. If two revisions are given, the differences between them are shown. The
--change option can also be used as a shortcut to list the changed files of a revision from its first parent.
The codes used to show the status of files are:
M = modified
A = added
R = removed
C = clean
! = missing (deleted by non-hg command, but still tracked)
? = not tracked
I = ignored
= origin of the previous file listed as A (added)
Examples:
o show changes in the working directory relative to a changeset:
hg status --rev 9353
o show all changes including copies in an existing changeset:
hg status --copies --change 9353
o get a NUL separated list of added files, suitable for xargs:
hg status -an0
Returns 0 on success.
Options:
-A, --all
show status of all files
-m, --modified
show only modified files
-a, --added
show only added files
-r, --removed
show only removed files
-d, --deleted
show only deleted (but tracked) files
-c, --clean
show only files without changes
-u, --unknown
show only unknown (not tracked) files
-i, --ignored
show only ignored files
-n, --no-status
hide status prefix
-C, --copies
show source of copied files
-0, --print0
end filenames with NUL, for use with xargs
--rev show difference from revision
--change
list the changed files of a revision
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-S, --subrepos
recurse into subrepositories
aliases: st
summary
hg summary [--remote]
This generates a brief summary of the working directory state, including parents, branch, commit status, and available updates.
With the --remote option, this will check the default paths for incoming and outgoing changes. This can be time-consuming.
Returns 0 on success.
Options:
--remote
check for push and pull
aliases: sum
tag
hg tag [-f] [-l] [-m TEXT] [-d DATE] [-u USER] [-r REV] NAME...
Name a particular revision using <name>.
Tags are used to name particular revisions of the repository and are very useful to compare different revisions, to go back to significant
earlier versions or to mark branch points as releases, etc. Changing an existing tag is normally disallowed; use -f/--force to override.
If no revision is given, the parent of the working directory is used, or tip if no revision is checked out.
To facilitate version control, distribution, and merging of tags, they are stored as a file named ".hgtags" which is managed similarly to
other project files and can be hand-edited if necessary. This also means that tagging creates a new commit. The file ".hg/localtags" is
used for local tags (not shared among repositories).
Tag commits are usually made at the head of a branch. If the parent of the working directory is not a branch head, hg tag aborts; use
-f/--force to force the tag commit to be based on a non-head changeset.
See hg help dates for a list of formats valid for -d/--date.
Since tag names have priority over branch names during revision lookup, using an existing branch name as a tag name is discouraged.
Returns 0 on success.
Options:
-f, --force
force tag
-l, --local
make the tag local
-r, --rev
revision to tag
--remove
remove a tag
-e, --edit
edit commit message
-m, --message
use <text> as commit message
-d, --date
record the specified date as commit date
-u, --user
record the specified user as committer
tags
hg tags
This lists both regular and local tags. When the -v/--verbose switch is used, a third column "local" is printed for local tags.
Returns 0 on success.
tip
hg tip [-p] [-g]
The tip revision (usually just called the tip) is the changeset most recently added to the repository (and therefore the most recently
changed head).
If you have just made a commit, that commit will be the tip. If you have just pulled changes from another repository, the tip of that
repository becomes the current tip. The "tip" tag is special and cannot be renamed or assigned to a different changeset.
Returns 0 on success.
Options:
-p, --patch
show patch
-g, --git
use git extended diff format
--style
display using template map file
--template
display with template
unbundle
hg unbundle [-u] FILE...
Apply one or more compressed changegroup files generated by the bundle command.
Returns 0 on success, 1 if an update has unresolved files.
Options:
-u, --update
update to new branch head if changesets were unbundled
update
hg update [-c] [-C] [-d DATE] [[-r] REV]
Update the repository's working directory to the specified changeset. If no changeset is specified, update to the tip of the current named
branch and move the current bookmark (see hg help bookmarks).
If the changeset is not a descendant of the working directory's parent, the update is aborted. With the -c/--check option, the working
directory is checked for uncommitted changes; if none are found, the working directory is updated to the specified changeset.
Update sets the working directory's parent revison to the specified changeset (see hg help parents).
The following rules apply when the working directory contains uncommitted changes:
1. If neither -c/--check nor -C/--clean is specified, and if the requested changeset is an ancestor or descendant of the working direc-
tory's parent, the uncommitted changes are merged into the requested changeset and the merged result is left uncommitted. If the
requested changeset is not an ancestor or descendant (that is, it is on another branch), the update is aborted and the uncommitted
changes are preserved.
2. With the -c/--check option, the update is aborted and the uncommitted changes are preserved.
3. With the -C/--clean option, uncommitted changes are discarded and the working directory is updated to the requested changeset.
Use null as the changeset to remove the working directory (like hg clone -U).
If you want to revert just one file to an older revision, use hg revert [-r REV] NAME.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success, 1 if there are unresolved files.
Options:
-C, --clean
discard uncommitted changes (no backup)
-c, --check
update across branches if no uncommitted changes
-d, --date
tipmost revision matching date
-r, --rev
revision
aliases: up checkout co
verify
hg verify
Verify the integrity of the current repository.
This will perform an extensive check of the repository's integrity, validating the hashes and checksums of each entry in the changelog,
manifest, and tracked files, as well as the integrity of their crosslinks and indices.
Returns 0 on success, 1 if errors are encountered.
version
hg version
output version and copyright information
DATE FORMATS
Some commands allow the user to specify a date, e.g.:
o backout, commit, import, tag: Specify the commit date.
o log, revert, update: Select revision(s) by date.
Many date formats are valid. Here are some examples:
o Wed Dec 6 13:18:29 2006 (local timezone assumed)
o Dec 6 13:18 -0600 (year assumed, time offset provided)
o Dec 6 13:18 UTC (UTC and GMT are aliases for +0000)
o Dec 6 (midnight)
o 13:18 (today assumed)
o 3:39 (3:39AM assumed)
o 3:39pm (15:39)
o 2006-12-06 13:18:29 (ISO 8601 format)
o 2006-12-6 13:18
o 2006-12-6
o 12-6
o 12/6
o 12/6/6 (Dec 6 2006)
Lastly, there is Mercurial's internal format:
o 1165432709 0 (Wed Dec 6 13:18:29 2006 UTC)
This is the internal representation format for dates. The first number is the number of seconds since the epoch (1970-01-01 00:00 UTC). The
second is the offset of the local timezone, in seconds west of UTC (negative if the timezone is east of UTC).
The log command also accepts date ranges:
o <DATE - at or before a given date/time
o >DATE - on or after a given date/time
o DATE to DATE - a date range, inclusive
o -DAYS - within a given number of days of today
DIFF FORMATS
Mercurial's default format for showing changes between two versions of a file is compatible with the unified format of GNU diff, which can
be used by GNU patch and many other standard tools.
While this standard format is often enough, it does not encode the following information:
o executable status and other permission bits
o copy or rename information
o changes in binary files
o creation or deletion of empty files
Mercurial also supports the extended diff format from the git VCS which addresses these limitations. The git diff format is not produced by
default because a few widespread tools still do not understand this format.
This means that when generating diffs from a Mercurial repository (e.g. with hg export), you should be careful about things like file
copies and renames or other things mentioned above, because when applying a standard diff to a different repository, this extra information
is lost. Mercurial's internal operations (like push and pull) are not affected by this, because they use an internal binary format for com-
municating changes.
To make Mercurial produce the git extended diff format, use the --git option available for many commands, or set 'git = True' in the [diff]
section of your configuration file. You do not need to set this option when importing diffs in this format or using them in the mq exten-
sion.
ENVIRONMENT VARIABLES
HG Path to the 'hg' executable, automatically passed when running hooks, extensions or external tools. If unset or empty, this is the
hg executable's name if it's frozen, or an executable named 'hg' (with %PATHEXT% [defaulting to COM/EXE/BAT/CMD] extensions on Win-
dows) is searched.
HGEDITOR
This is the name of the editor to run when committing. See EDITOR.
(deprecated, use configuration file)
HGENCODING
This overrides the default locale setting detected by Mercurial. This setting is used to convert data including usernames, change-
set descriptions, tag names, and branches. This setting can be overridden with the --encoding command-line option.
HGENCODINGMODE
This sets Mercurial's behavior for handling unknown characters while transcoding user input. The default is "strict", which causes
Mercurial to abort if it can't map a character. Other settings include "replace", which replaces unknown characters, and "ignore",
which drops them. This setting can be overridden with the --encodingmode command-line option.
HGENCODINGAMBIGUOUS
This sets Mercurial's behavior for handling characters with "ambiguous" widths like accented Latin characters with East Asian fonts.
By default, Mercurial assumes ambiguous characters are narrow, set this variable to "wide" if such characters cause formatting prob-
lems.
HGMERGE
An executable to use for resolving merge conflicts. The program will be executed with three arguments: local file, remote file,
ancestor file.
(deprecated, use configuration file)
HGRCPATH
A list of files or directories to search for configuration files. Item separator is ":" on Unix, ";" on Windows. If HGRCPATH is not
set, platform default search path is used. If empty, only the .hg/hgrc from the current repository is read.
For each element in HGRCPATH:
o if it's a directory, all files ending with .rc are added
o otherwise, the file itself will be added
HGPLAIN
When set, this disables any configuration settings that might change Mercurial's default output. This includes encoding, defaults,
verbose mode, debug mode, quiet mode, tracebacks, and localization. This can be useful when scripting against Mercurial in the face
of existing user configuration.
Equivalent options set via command line flags or environment variables are not overridden.
HGPLAINEXCEPT
This is a comma-separated list of features to preserve when HGPLAIN is enabled. Currently the only value supported is "i18n", which
preserves internationalization in plain mode.
Setting HGPLAINEXCEPT to anything (even an empty string) will enable plain mode.
HGUSER This is the string used as the author of a commit. If not set, available values will be considered in this order:
o HGUSER (deprecated)
o configuration files from the HGRCPATH
o EMAIL
o interactive prompt
o LOGNAME (with @hostname appended)
(deprecated, use configuration file)
EMAIL May be used as the author of a commit; see HGUSER.
LOGNAME
May be used as the author of a commit; see HGUSER.
VISUAL This is the name of the editor to use when committing. See EDITOR.
EDITOR Sometimes Mercurial needs to open a text file in an editor for a user to modify, for example when writing commit messages. The edi-
tor it uses is determined by looking at the environment variables HGEDITOR, VISUAL and EDITOR, in that order. The first non-empty
one is chosen. If all of them are empty, the editor defaults to 'sensible-editor'.
PYTHONPATH
This is used by Python to find imported modules and may need to be set appropriately if this Mercurial is not installed system-wide.
USING ADDITIONAL FEATURES
Mercurial has the ability to add new features through the use of extensions. Extensions may add new commands, add options to existing com-
mands, change the default behavior of commands, or implement hooks.
Extensions are not loaded by default for a variety of reasons: they can increase startup overhead; they may be meant for advanced usage
only; they may provide potentially dangerous abilities (such as letting you destroy or modify history); they might not be ready for prime
time; or they may alter some usual behaviors of stock Mercurial. It is thus up to the user to activate extensions as needed.
To enable the "foo" extension, either shipped with Mercurial or in the Python search path, create an entry for it in your configuration
file, like this:
[extensions]
foo =
You may also specify the full path to an extension:
[extensions]
myfeature = ~/.hgext/myfeature.py
To explicitly disable an extension enabled in a configuration file of broader scope, prepend its path with !:
[extensions]
# disabling extension bar residing in /path/to/extension/bar.py
bar = !/path/to/extension/bar.py
# ditto, but no path was supplied for extension baz
baz = !

SPECIFYING FILE SETS
Mercurial supports a functional language for selecting a set of files.
Like other file patterns, this pattern type is indicated by a prefix, 'set:'. The language supports a number of predicates which are joined
by infix operators. Parenthesis can be used for grouping.
Identifiers such as filenames or patterns must be quoted with single or double quotes if they contain characters outside of
[.*{}[]?/\_a-zA-Z0-9x80-xff] or if they match one of the predefined predicates. This generally applies to file patterns other than globs
and arguments for predicates.
Special characters can be used in quoted identifiers by escaping them, e.g.,
is interpreted as a newline. To prevent them from being
interpreted, strings can be prefixed with r, e.g. r'...'.
There is a single prefix operator:
not x
Files not in x. Short form is ! x.
These are the supported infix operators:
x and y
The intersection of files in x and y. Short form is x & y.
x or y
The union of files in x and y. There are two alternative short forms: x | y and x + y.
x - y
Files in x but not in y.
The following predicates are supported:
added()
File that is added according to status.
binary()
File that appears to be binary (contains NUL bytes).
clean()
File that is clean according to status.
copied()
File that is recorded as being copied.
deleted()
File that is deleted according to status.
encoding(name)
File can be successfully decoded with the given character encoding. May not be useful for encodings other than ASCII and UTF-8.
exec()
File that is marked as executable.
grep(regex)
File contains the given regular expression.
hgignore()
File that matches the active .hgignore pattern.
ignored()
File that is ignored according to status. These files will only be considered if this predicate is used.
modified()
File that is modified according to status.
removed()
File that is removed according to status.
resolved()
File that is marked resolved according to the resolve state.
size(expression)
File size matches the given expression. Examples:
o 1k (files from 1024 to 2047 bytes)
o < 20k (files less than 20480 bytes)
o >= .5MB (files at least 524288 bytes)
o 4k - 1MB (files from 4096 bytes to 1048576 bytes)
subrepo([pattern])
Subrepositories whose paths match the given pattern.
symlink()
File that is marked as a symlink.
unknown()
File that is unknown according to status. These files will only be considered if this predicate is used.
unresolved()
File that is marked unresolved according to the resolve state.
Some sample queries:
o Show status of files that appear to be binary in the working directory:
hg status -A "set:binary()"
o Forget files that are in .hgignore but are already tracked:
hg forget "set:hgignore() and not ignored()"
o Find text files that contain a string:
hg locate "set:grep(magic) and not binary()"
o Find C files in a non-standard encoding:
hg locate "set:**.c and not encoding('UTF-8')"
o Revert copies of large binary files:
hg revert "set:copied() and binary() and size('>1M')"
o Remove files listed in foo.lst that contain the letter a or b:
hg remove "set: 'listfile:foo.lst' and (**a* or **b*)"
See also hg help patterns.
GLOSSARY
Ancestor
Any changeset that can be reached by an unbroken chain of parent changesets from a given changeset. More precisely, the ancestors of
a changeset can be defined by two properties: a parent of a changeset is an ancestor, and a parent of an ancestor is an ancestor.
See also: 'Descendant'.
Bookmark
Bookmarks are pointers to certain commits that move when committing. They are similar to tags in that it is possible to use bookmark
names in all places where Mercurial expects a changeset ID, e.g., with hg update. Unlike tags, bookmarks move along when you make a
commit.
Bookmarks can be renamed, copied and deleted. Bookmarks are local, unless they are explicitly pushed or pulled between repositories.
Pushing and pulling bookmarks allow you to collaborate with others on a branch without creating a named branch.
Branch (Noun) A child changeset that has been created from a parent that is not a head. These are known as topological branches, see
'Branch, topological'. If a topological branch is named, it becomes a named branch. If a topological branch is not named, it becomes
an anonymous branch. See 'Branch, anonymous' and 'Branch, named'.
Branches may be created when changes are pulled from or pushed to a remote repository, since new heads may be created by these oper-
ations. Note that the term branch can also be used informally to describe a development process in which certain development is done
independently of other development. This is sometimes done explicitly with a named branch, but it can also be done locally, using
bookmarks or clones and anonymous branches.
Example: "The experimental branch".
(Verb) The action of creating a child changeset which results in its parent having more than one child.
Example: "I'm going to branch at X".
Branch, anonymous
Every time a new child changeset is created from a parent that is not a head and the name of the branch is not changed, a new anony-
mous branch is created.
Branch, closed
A named branch whose branch heads have all been closed.
Branch, default
The branch assigned to a changeset when no name has previously been assigned.
Branch head
See 'Head, branch'.
Branch, inactive
If a named branch has no topological heads, it is considered to be inactive. As an example, a feature branch becomes inactive when
it is merged into the default branch. The hg branches command shows inactive branches by default, though they can be hidden with hg
branches --active.
NOTE: this concept is deprecated because it is too implicit. Branches should now be explicitly closed using hg commit
--close-branch when they are no longer needed.
Branch, named
A collection of changesets which have the same branch name. By default, children of a changeset in a named branch belong to the same
named branch. A child can be explicitly assigned to a different branch. See hg help branch, hg help branches and hg commit
--close-branch for more information on managing branches.
Named branches can be thought of as a kind of namespace, dividing the collection of changesets that comprise the repository into a
collection of disjoint subsets. A named branch is not necessarily a topological branch. If a new named branch is created from the
head of another named branch, or the default branch, but no further changesets are added to that previous branch, then that previous
branch will be a branch in name only.
Branch tip
See 'Tip, branch'.
Branch, topological
Every time a new child changeset is created from a parent that is not a head, a new topological branch is created. If a topological
branch is named, it becomes a named branch. If a topological branch is not named, it becomes an anonymous branch of the current,
possibly default, branch.
Changelog
A record of the changesets in the order in which they were added to the repository. This includes details such as changeset id,
author, commit message, date, and list of changed files.
Changeset
A snapshot of the state of the repository used to record a change.
Changeset, child
The converse of parent changeset: if P is a parent of C, then C is a child of P. There is no limit to the number of children that a
changeset may have.
Changeset id
A SHA-1 hash that uniquely identifies a changeset. It may be represented as either a "long" 40 hexadecimal digit string, or a
"short" 12 hexadecimal digit string.
Changeset, merge
A changeset with two parents. This occurs when a merge is committed.
Changeset, parent
A revision upon which a child changeset is based. Specifically, a parent changeset of a changeset C is a changeset whose node imme-
diately precedes C in the DAG. Changesets have at most two parents.
Checkout
(Noun) The working directory being updated to a specific revision. This use should probably be avoided where possible, as changeset
is much more appropriate than checkout in this context.
Example: "I'm using checkout X."
(Verb) Updating the working directory to a specific changeset. See hg help update.
Example: "I'm going to check out changeset X."
Child changeset
See 'Changeset, child'.
Close changeset
See 'Head, closed branch'
Closed branch
See 'Branch, closed'.
Clone (Noun) An entire or partial copy of a repository. The partial clone must be in the form of a revision and its ancestors.
Example: "Is your clone up to date?".
(Verb) The process of creating a clone, using hg clone.
Example: "I'm going to clone the repository".
Closed branch head
See 'Head, closed branch'.
Commit (Noun) A synonym for changeset.
Example: "Is the bug fixed in your recent commit?"
(Verb) The act of recording changes to a repository. When files are committed in a working directory, Mercurial finds the differ-
ences between the committed files and their parent changeset, creating a new changeset in the repository.
Example: "You should commit those changes now."
Cset A common abbreviation of the term changeset.
DAG The repository of changesets of a distributed version control system (DVCS) can be described as a directed acyclic graph (DAG), con-
sisting of nodes and edges, where nodes correspond to changesets and edges imply a parent -> child relation. This graph can be visu-
alized by graphical tools such as hg glog (graphlog). In Mercurial, the DAG is limited by the requirement for children to have at
most two parents.
Default branch
See 'Branch, default'.
Descendant
Any changeset that can be reached by a chain of child changesets from a given changeset. More precisely, the descendants of a
changeset can be defined by two properties: the child of a changeset is a descendant, and the child of a descendant is a descendant.
See also: 'Ancestor'.
Diff (Noun) The difference between the contents and attributes of files in two changesets or a changeset and the current working direc-
tory. The difference is usually represented in a standard form called a "diff" or "patch". The "git diff" format is used when the
changes include copies, renames, or changes to file attributes, none of which can be represented/handled by classic "diff" and
"patch".
Example: "Did you see my correction in the diff?"
(Verb) Diffing two changesets is the action of creating a diff or patch.
Example: "If you diff with changeset X, you will see what I mean."
Directory, working
The working directory represents the state of the files tracked by Mercurial, that will be recorded in the next commit. The working
directory initially corresponds to the snapshot at an existing changeset, known as the parent of the working directory. See 'Parent,
working directory'. The state may be modified by changes to the files introduced manually or by a merge. The repository metadata
exists in the .hg directory inside the working directory.
Draft Changesets in the draft phase have not been shared with publishing repositories and may thus be safely changed by history-modifying
extensions. See hg help phases.
Graph See DAG and hg help graphlog.
Head The term 'head' may be used to refer to both a branch head or a repository head, depending on the context. See 'Head, branch' and
'Head, repository' for specific definitions.
Heads are where development generally takes place and are the usual targets for update and merge operations.
Head, branch
A changeset with no descendants on the same named branch.
Head, closed branch
A changeset that marks a head as no longer interesting. The closed head is no longer listed by hg heads. A branch is considered
closed when all its heads are closed and consequently is not listed by hg branches.
Closed heads can be re-opened by committing new changeset as the child of the changeset that marks a head as closed.
Head, repository
A topological head which has not been closed.
Head, topological
A changeset with no children in the repository.
History, immutable
Once committed, changesets cannot be altered. Extensions which appear to change history actually create new changesets that replace
existing ones, and then destroy the old changesets. Doing so in public repositories can result in old changesets being reintroduced
to the repository.
History, rewriting
The changesets in a repository are immutable. However, extensions to Mercurial can be used to alter the repository, usually in such
a way as to preserve changeset contents.
Immutable history
See 'History, immutable'.
Merge changeset
See 'Changeset, merge'.
Manifest
Each changeset has a manifest, which is the list of files that are tracked by the changeset.
Merge Used to bring together divergent branches of work. When you update to a changeset and then merge another changeset, you bring the
history of the latter changeset into your working directory. Once conflicts are resolved (and marked), this merge may be committed
as a merge changeset, bringing two branches together in the DAG.
Named branch
See 'Branch, named'.
Null changeset
The empty changeset. It is the parent state of newly-initialized repositories and repositories with no checked out revision. It is
thus the parent of root changesets and the effective ancestor when merging unrelated changesets. Can be specified by the alias
'null' or by the changeset ID '000000000000'.
Parent See 'Changeset, parent'.
Parent changeset
See 'Changeset, parent'.
Parent, working directory
The working directory parent reflects a virtual revision which is the child of the changeset (or two changesets with an uncommitted
merge) shown by hg parents. This is changed with hg update. Other commands to see the working directory parent are hg summary and hg
id. Can be specified by the alias ".".
Patch (Noun) The product of a diff operation.
Example: "I've sent you my patch."
(Verb) The process of using a patch file to transform one changeset into another.
Example: "You will need to patch that revision."
Phase A per-changeset state tracking how the changeset has been or should be shared. See hg help phases.
Public Changesets in the public phase have been shared with publishing repositories and are therefore considered immutable. See hg help
phases.
Pull An operation in which changesets in a remote repository which are not in the local repository are brought into the local repository.
Note that this operation without special arguments only updates the repository, it does not update the files in the working direc-
tory. See hg help pull.
Push An operation in which changesets in a local repository which are not in a remote repository are sent to the remote repository. Note
that this operation only adds changesets which have been committed locally to the remote repository. Uncommitted changes are not
sent. See hg help push.
Repository
The metadata describing all recorded states of a collection of files. Each recorded state is represented by a changeset. A reposi-
tory is usually (but not always) found in the .hg subdirectory of a working directory. Any recorded state can be recreated by
"updating" a working directory to a specific changeset.
Repository head
See 'Head, repository'.
Revision
A state of the repository at some point in time. Earlier revisions can be updated to by using hg update. See also 'Revision num-
ber'; See also 'Changeset'.
Revision number
This integer uniquely identifies a changeset in a specific repository. It represents the order in which changesets were added to a
repository, starting with revision number 0. Note that the revision number may be different in each clone of a repository. To iden-
tify changesets uniquely between different clones, see 'Changeset id'.
Revlog History storage mechanism used by Mercurial. It is a form of delta encoding, with occasional full revision of data followed by delta
of each successive revision. It includes data and an index pointing to the data.
Rewriting history
See 'History, rewriting'.
Root A changeset that has only the null changeset as its parent. Most repositories have only a single root changeset.
Secret Changesets in the secret phase may not be shared via push, pull, or clone. See hg help phases.
Tag An alternative name given to a changeset. Tags can be used in all places where Mercurial expects a changeset ID, e.g., with hg
update. The creation of a tag is stored in the history and will thus automatically be shared with other using push and pull.
Tip The changeset with the highest revision number. It is the changeset most recently added in a repository.
Tip, branch
The head of a given branch with the highest revision number. When a branch name is used as a revision identifier, it refers to the
branch tip. See also 'Branch, head'. Note that because revision numbers may be different in different repository clones, the branch
tip may be different in different cloned repositories.
Update (Noun) Another synonym of changeset.
Example: "I've pushed an update".
(Verb) This term is usually used to describe updating the state of the working directory to that of a specific changeset. See hg
help update.
Example: "You should update".
Working directory
See 'Directory, working'.
Working directory parent
See 'Parent, working directory'.
SYNTAX FOR MERCURIAL IGNORE FILES
SYNOPSIS
The Mercurial system uses a file called .hgignore in the root directory of a repository to control its behavior when it searches for files
that it is not currently tracking.
DESCRIPTION
The working directory of a Mercurial repository will often contain files that should not be tracked by Mercurial. These include backup
files created by editors and build products created by compilers. These files can be ignored by listing them in a .hgignore file in the
root of the working directory. The .hgignore file must be created manually. It is typically put under version control, so that the settings
will propagate to other repositories with push and pull.
An untracked file is ignored if its path relative to the repository root directory, or any prefix path of that path, is matched against any
pattern in .hgignore.
For example, say we have an untracked file, file.c, at a/b/file.c inside our repository. Mercurial will ignore file.c if any pattern in
.hgignore matches a/b/file.c, a/b or a.
In addition, a Mercurial configuration file can reference a set of per-user or global ignore files. See the ignore configuration key on the
[ui] section of hg help config for details of how to configure these files.
To control Mercurial's handling of files that it manages, many commands support the -I and -X options; see hg help <command> and hg help
patterns for details.

An ignore file is a plain text file consisting of a list of patterns, with one pattern per line. Empty lines are skipped. The # character
is treated as a comment character, and the character is treated as an escape character.
Mercurial supports several pattern syntaxes. The default syntax used is Python/Perl-style regular expressions.
To change the syntax used, use a line of the following form:
syntax: NAME
where NAME is one of the following:
regexp
Regular expression, Python/Perl syntax.
glob
Shell-style glob.
The chosen syntax stays in effect when parsing all patterns that follow, until another syntax is selected.
Neither glob nor regexp patterns are rooted. A glob-syntax pattern of the form *.c will match a file ending in .c in any directory, and a
regexp pattern of the form .c$ will do the same. To root a regexp pattern, start it with ^.
Note Patterns specified in other than .hgignore are always rooted. Please see hg help patterns for details.
EXAMPLE
Here is an example ignore file.
# use glob syntax.
syntax: glob
*.elc
*.pyc
*~
# switch to regexp syntax.
syntax: regexp
^.pc/
CONFIGURING HGWEB
Mercurial's internal web server, hgweb, can serve either a single repository, or a collection of them. In the latter case, a special con-
figuration file can be used to specify the repository paths to use and global web configuration options.
This file uses the same syntax as other Mercurial configuration files, but only the following sections are recognized:
o web
o paths
o collections
The web section can specify all the settings described in the web section of the hgrc(5) documentation. See hg help config for information
on where to find the manual page.
The paths section provides mappings of physical repository paths to virtual ones. For instance:
[paths]
projects/a = /foo/bar
projects/b = /baz/quux
web/root = /real/root/*
/ = /real/root2/*
virtual/root2 = /real/root2/**
o The first two entries make two repositories in different directories appear under the same directory in the web interface
o The third entry maps every Mercurial repository found in '/real/root' into 'web/root'. This format is preferred over the [collections]
one, since using absolute paths as configuration keys is not supported on every platform (especially on Windows).
o The fourth entry is a special case mapping all repositories in '/real/root2' in the root of the virtual directory.
o The fifth entry recursively finds all repositories under the real root, and maps their relative paths under the virtual root.
The collections section provides mappings of trees of physical repositories paths to virtual ones, though the paths syntax is generally
preferred. For instance:
[collections]
/foo = /foo
Here, the left side will be stripped off all repositories found in the right side. Thus /foo/bar and foo/quux/baz will be listed as bar and
quux/baz respectively.
MERGE TOOLS
To merge files Mercurial uses merge tools.
A merge tool combines two different versions of a file into a merged file. Merge tools are given the two files and the greatest common
ancestor of the two file versions, so they can determine the changes made on both branches.
Merge tools are used both for hg resolve, hg merge, hg update, hg backout and in several extensions.
Usually, the merge tool tries to automatically reconcile the files by combining all non-overlapping changes that occurred separately in the
two different evolutions of the same initial base file. Furthermore, some interactive merge programs make it easier to manually resolve
conflicting merges, either in a graphical way, or by inserting some conflict markers. Mercurial does not include any interactive merge pro-
grams but relies on external tools for that.
Available merge tools
External merge tools and their properties are configured in the merge-tools configuration section - see hgrc(5) - but they can often just
be named by their executable.
A merge tool is generally usable if its executable can be found on the system and if it can handle the merge. The executable is found if it
is an absolute or relative executable path or the name of an application in the executable search path. The tool is assumed to be able to
handle the merge if it can handle symlinks if the file is a symlink, if it can handle binary files if the file is binary, and if a GUI is
available if the tool requires a GUI.
There are some internal merge tools which can be used. The internal merge tools are:
internal:dump
Creates three versions of the files to merge, containing the contents of local, other and base. These files can then be used to per-
form a merge manually. If the file to be merged is named a.txt, these files will accordingly be named a.txt.local, a.txt.other and
a.txt.base and they will be placed in the same directory as a.txt.
internal:fail
Rather than attempting to merge files that were modified on both branches, it marks them as unresolved. The resolve command must be
used to resolve these conflicts.
internal:local
Uses the local version of files as the merged version.
internal:merge
Uses the internal non-interactive simple merge algorithm for merging files. It will fail if there are any conflicts and leave mark-
ers in the partially merged file.
internal:other
Uses the other version of files as the merged version.
internal:prompt
Asks the user which of the local or the other version to keep as the merged version.
Internal tools are always available and do not require a GUI but will by default not handle symlinks or binary files.
Choosing a merge tool
Mercurial uses these rules when deciding which merge tool to use:
1. If a tool has been specified with the --tool option to merge or resolve, it is used. If it is the name of a tool in the merge-tools
configuration, its configuration is used. Otherwise the specified tool must be executable by the shell.
2. If the HGMERGE environment variable is present, its value is used and must be executable by the shell.
3. If the filename of the file to be merged matches any of the patterns in the merge-patterns configuration section, the first usable merge
tool corresponding to a matching pattern is used. Here, binary capabilities of the merge tool are not considered.
4. If ui.merge is set it will be considered next. If the value is not the name of a configured tool, the specified value is used and must
be executable by the shell. Otherwise the named tool is used if it is usable.
5. If any usable merge tools are present in the merge-tools configuration section, the one with the highest priority is used.
6. If a program named hgmerge can be found on the system, it is used - but it will by default not be used for symlinks and binary files.
7. If the file to be merged is not binary and is not a symlink, then internal:merge is used.
8. The merge of the file fails and must be resolved before commit.
Note After selecting a merge program, Mercurial will by default attempt to merge the files using a simple merge algorithm first. Only if
it doesn't succeed because of conflicting changes Mercurial will actually execute the merge program. Whether to use the simple merge
algorithm first can be controlled by the premerge setting of the merge tool. Premerge is enabled by default unless the file is
binary or a symlink.
See the merge-tools and ui sections of hgrc(5) for details on the configuration of merge tools.
SPECIFYING MULTIPLE REVISIONS
When Mercurial accepts more than one revision, they may be specified individually, or provided as a topologically continuous range, sepa-
rated by the ":" character.
The syntax of range notation is [BEGIN]:[END], where BEGIN and END are revision identifiers. Both BEGIN and END are optional. If BEGIN is
not specified, it defaults to revision number 0. If END is not specified, it defaults to the tip. The range ":" thus means "all revisions".
If BEGIN is greater than END, revisions are treated in reverse order.
A range acts as a closed interval. This means that a range of 3:5 gives 3, 4 and 5. Similarly, a range of 9:6 gives 9, 8, 7, and 6.
FILE NAME PATTERNS
Mercurial accepts several notations for identifying one or more files at a time.
By default, Mercurial treats filenames as shell-style extended glob patterns.
Alternate pattern notations must be specified explicitly.
Note Patterns specified in .hgignore are not rooted. Please see hg help hgignore for details.
To use a plain path name without any pattern matching, start it with path:. These path names must completely match starting at the current
repository root.
To use an extended glob, start a name with glob:. Globs are rooted at the current directory; a glob such as *.c will only match files in
the current directory ending with .c.
The supported glob syntax extensions are ** to match any string across path separators and {a,b} to mean "a or b".
To use a Perl/Python regular expression, start a name with re:. Regexp pattern matching is anchored at the root of the repository.
To read name patterns from a file, use listfile: or listfile0:. The latter expects null delimited patterns while the former expects line
feeds. Each string read from the file is itself treated as a file pattern.
Plain examples:
path:foo/bar a name bar in a directory named foo in the root
of the repository
path:path:name a file or directory named "path:name"
Glob examples:
glob:*.c any name ending in ".c" in the current directory
*.c any name ending in ".c" in the current directory
**.c any name ending in ".c" in any subdirectory of the
current directory including itself.
foo/*.c any name ending in ".c" in the directory foo
foo/**.c any name ending in ".c" in any subdirectory of foo
including itself.
Regexp examples:
re:.*.c$ any name ending in ".c", anywhere in the repository
File examples:
listfile:list.txt read list from list.txt with one file pattern per line
listfile0:list.txt read list from list.txt with null byte delimiters
See also hg help filesets.
WORKING WITH PHASES
WHAT ARE PHASES
?
Phases are a system for tracking which changesets have been or should be shared. This helps prevent common mistakes when modifying history
(for instance, with the mq or rebase extensions).
Each changeset in a repository is in one of the following phases:
o public : changeset is visible on a public server
o draft : changeset is not yet published
o secret : changeset should not be pushed, pulled, or cloned
These phases are ordered (public < draft < secret) and no changeset can be in a lower phase than its ancestors. For instance, if a change-
set is public, all its ancestors are also public. Lastly, changeset phases should only be changed towards the public phase.
HOW ARE PHASES MANAGED
?
For the most part, phases should work transparently. By default, a changeset is created in the draft phase and is moved into the public
phase when it is pushed to another repository.
Once changesets become public, extensions like mq and rebase will refuse to operate on them to prevent creating duplicate changesets.
Phases can also be manually manipulated with the hg phase command if needed. See hg help -v phase for examples.
PHASES AND SERVERS
Normally, all servers are publishing by default. This means:
- all draft changesets that are pulled or cloned appear in phase
public on the client
- all draft changesets that are pushed appear as public on both
client and server
- secret changesets are neither pushed, pulled, or cloned
Note Pulling a draft changeset from a publishing server does not mark it as public on the server side due to the read-only nature of
pull.
Sometimes it may be desirable to push and pull changesets in the draft phase to share unfinished work. This can be done by setting a repos-
itory to disable publishing in its configuration file:
[phases]
publish = False
See hg help config for more information on config files.
Note Servers running older versions of Mercurial are treated as publishing.
EXAMPLES
o list changesets in draft or secret phase:
hg log -r "not public()"
o change all secret changesets to draft:
hg phase --draft "secret()"
o forcibly move the current changeset and descendants from public to draft:
hg phase --force --draft .
o show a list of changeset revision and phase:
hg log --template "{rev} {phase}
"
o resynchronize draft changesets relative to a remote repository:
hg phase -fd 'outgoing(URL)'
See hg help phase for more information on manually manipulating phases.
SPECIFYING SINGLE REVISIONS
Mercurial supports several ways to specify individual revisions.
A plain integer is treated as a revision number. Negative integers are treated as sequential offsets from the tip, with -1 denoting the
tip, -2 denoting the revision prior to the tip, and so forth.
A 40-digit hexadecimal string is treated as a unique revision identifier.
A hexadecimal string less than 40 characters long is treated as a unique revision identifier and is referred to as a short-form identifier.
A short-form identifier is only valid if it is the prefix of exactly one full-length identifier.
Any other string is treated as a tag or branch name. A tag name is a symbolic name associated with a revision identifier. A branch name
denotes the tipmost revision of that branch. Tag and branch names must not contain the ":" character.
The reserved name "tip" is a special tag that always identifies the most recent revision.
The reserved name "null" indicates the null revision. This is the revision of an empty repository, and the parent of revision 0.
The reserved name "." indicates the working directory parent. If no working directory is checked out, it is equivalent to null. If an
uncommitted merge is in progress, "." is the revision of the first parent.
SPECIFYING REVISION SETS
Mercurial supports a functional language for selecting a set of revisions.
The language supports a number of predicates which are joined by infix operators. Parenthesis can be used for grouping.
Identifiers such as branch names may need quoting with single or double quotes if they contain characters like - or if they match one of
the predefined predicates.
Special characters can be used in quoted identifiers by escaping them, e.g.,
is interpreted as a newline. To prevent them from being
interpreted, strings can be prefixed with r, e.g. r'...'.
There is a single prefix operator:
not x
Changesets not in x. Short form is ! x.
These are the supported infix operators:
x::y
A DAG range, meaning all changesets that are descendants of x and ancestors of y, including x and y themselves. If the first end-
point is left out, this is equivalent to ancestors(y), if the second is left out it is equivalent to descendants(x).
An alternative syntax is x..y.
x:y
All changesets with revision numbers between x and y, both inclusive. Either endpoint can be left out, they default to 0 and tip.
x and y
The intersection of changesets in x and y. Short form is x & y.
x or y
The union of changesets in x and y. There are two alternative short forms: x | y and x + y.
x - y
Changesets in x but not in y.
x^n
The nth parent of x, n == 0, 1, or 2. For n == 0, x; for n == 1, the first parent of each changeset in x; for n == 2, the second
parent of changeset in x.
x~n
The nth first ancestor of x; x~0 is x; x~3 is x^^^.
There is a single postfix operator:
x^
Equivalent to x^1, the first parent of each changeset in x.
The following predicates are supported:
adds(pattern)
Changesets that add a file matching pattern.
all()
All changesets, the same as 0:tip.
ancestor(single, single)
Greatest common ancestor of the two changesets.
ancestors(set)
Changesets that are ancestors of a changeset in set.
author(string)
Alias for user(string).
bisect(string)
Changesets marked in the specified bisect status:
o good, bad, skip: csets explicitly marked as good/bad/skip
o goods, bads : csets topologicaly good/bad
o range : csets taking part in the bisection
o pruned : csets that are goods, bads or skipped
o untested : csets whose fate is yet unknown
o ignored : csets ignored due to DAG topology
bookmark([name])
The named bookmark or all bookmarks.
branch(string or set)
All changesets belonging to the given branch or the branches of the given changesets.
children(set)
Child changesets of changesets in set.
closed()
Changeset is closed.
contains(pattern)
Revision contains a file matching pattern. See hg help patterns for information about file patterns.
date(interval)
Changesets within the interval, see hg help dates.
desc(string)
Search commit message for string. The match is case-insensitive.
descendants(set)
Changesets which are descendants of changesets in set.
draft()
Changeset in draft phase.
file(pattern)
Changesets affecting files matched by pattern.
filelog(pattern)
Changesets connected to the specified filelog.
first(set, [n])
An alias for limit().
follow([file])
An alias for ::. (ancestors of the working copy's first parent). If a filename is specified, the history of the given file is fol-
lowed, including copies.
grep(regex)
Like keyword(string) but accepts a regex. Use grep(r'...') to ensure special escape characters are handled correctly. Unlike key-
word(string), the match is case-sensitive.
head()
Changeset is a named branch head.
heads(set)
Members of set with no children in set.
id(string)
Revision non-ambiguously specified by the given hex string prefix.
keyword(string)
Search commit message, user name, and names of changed files for string. The match is case-insensitive.
last(set, [n])
Last n members of set, defaulting to 1.
limit(set, [n])
First n members of set, defaulting to 1.
matching(revision [, field])
Changesets in which a given set of fields match the set of fields in the selected revision or set.
To match more than one field pass the list of fields to match separated by spaces (e.g. author description).
Valid fields are most regular revision fields and some special fields.
Regular revision fields are description, author, branch, date, files, phase, parents, substate and user. Note that author and user
are synonyms.
Special fields are summary and metadata: summary matches the first line of the description. metadata is equivalent to matching
description user date (i.e. it matches the main metadata fields).
metadata is the default field which is used when no fields are specified. You can match more than one field at a time.
max(set)
Changeset with highest revision number in set.
merge()
Changeset is a merge changeset.
min(set)
Changeset with lowest revision number in set.
modifies(pattern)
Changesets modifying files matched by pattern.
outgoing([path])
Changesets not found in the specified destination repository, or the default push location.
p1([set])
First parent of changesets in set, or the working directory.
p2([set])
Second parent of changesets in set, or the working directory.
parents([set])
The set of all parents for all changesets in set, or the working directory.
present(set)
An empty set, if any revision in set isn't found; otherwise, all revisions in set.
If any of specified revisions is not present in the local repository, the query is normally aborted. But this predicate allows the
query to continue even in such cases.
public()
Changeset in public phase.
remote([id [,path]])
Local revision that corresponds to the given identifier in a remote repository, if present. Here, the '.' identifier is a synonym
for the current local branch.
removes(pattern)
Changesets which remove files matching pattern.
rev(number)
Revision with the given numeric identifier.
reverse(set)
Reverse order of set.
roots(set)
Changesets in set with no parent changeset in set.
secret()
Changeset in secret phase.
sort(set[, [-]key...])
Sort set by keys. The default sort order is ascending, specify a key as -key to sort in descending order.
The keys can be:
o rev for the revision number,
o branch for the branch name,
o desc for the commit message (description),
o user for user name (author can be used as an alias),
o date for the commit date
tag([name])
The specified tag by name, or all tagged revisions if no name is given.
user(string)
User name contains string. The match is case-insensitive.
New predicates (known as "aliases") can be defined, using any combination of existing predicates or other aliases. An alias definition
looks like:
<alias> = <definition>
in the revsetalias section of a Mercurial configuration file. Arguments of the form $1, $2, etc. are substituted from the alias into the
definition.
For example,
[revsetalias]
h = heads()
d($1) = sort($1, date)
rs($1, $2) = reverse(sort($1, $2))
defines three aliases, h, d, and rs. rs(0:tip, author) is exactly equivalent to reverse(sort(0:tip, author)).
Command line equivalents for hg log:
-f -> ::.
-d x -> date(x)
-k x -> keyword(x)
-m -> merge()
-u x -> user(x)
-b x -> branch(x)
-P x -> !::x
-l x -> limit(expr, x)
Some sample queries:
o Changesets on the default branch:
hg log -r "branch(default)"
o Changesets on the default branch since tag 1.5 (excluding merges):
hg log -r "branch(default) and 1.5:: and not merge()"
o Open branch heads:
hg log -r "head() and not closed()"
o Changesets between tags 1.3 and 1.5 mentioning "bug" that affect hgext/*:
hg log -r "1.3::1.5 and keyword(bug) and file('hgext/*')"
o Changesets committed in May 2008, sorted by user:
hg log -r "sort(date('May 2008'), user)"
o Changesets mentioning "bug" or "issue" that are not in a tagged release:
hg log -r "(keyword(bug) or keyword(issue)) and not ancestors(tagged())"
SUBREPOSITORIES
Subrepositories let you nest external repositories or projects into a parent Mercurial repository, and make commands operate on them as a
group.
Mercurial currently supports Mercurial, Git, and Subversion subrepositories.
Subrepositories are made of three components:
1. Nested repository checkouts. They can appear anywhere in the parent working directory.
2. Nested repository references. They are defined in .hgsub, which should be placed in the root of working directory, and tell where the
subrepository checkouts come from. Mercurial subrepositories are referenced like:
path/to/nested = https://example.com/nested/repo/path
Git and Subversion subrepos are also supported:
path/to/nested = [git]git://example.com/nested/repo/path path/to/nested = [svn]https://example.com/nested/trunk/path
where path/to/nested is the checkout location relatively to the parent Mercurial root, and https://example.com/nested/repo/path is the
source repository path. The source can also reference a filesystem path.
Note that .hgsub does not exist by default in Mercurial repositories, you have to create and add it to the parent repository before
using subrepositories.
3. Nested repository states. They are defined in .hgsubstate, which is placed in the root of working directory, and capture whatever infor-
mation is required to restore the subrepositories to the state they were committed in a parent repository changeset. Mercurial automati-
cally record the nested repositories states when committing in the parent repository.
Note
The .hgsubstate file should not be edited manually.
ADDING A SUBREPOSITORY
If .hgsub does not exist, create it and add it to the parent repository. Clone or checkout the external projects where you want it to live
in the parent repository. Edit .hgsub and add the subrepository entry as described above. At this point, the subrepository is tracked and
the next commit will record its state in .hgsubstate and bind it to the committed changeset.
SYNCHRONIZING A SUBREPOSITORY
Subrepos do not automatically track the latest changeset of their sources. Instead, they are updated to the changeset that corresponds with
the changeset checked out in the top-level changeset. This is so developers always get a consistent set of compatible code and libraries
when they update.
Thus, updating subrepos is a manual process. Simply check out target subrepo at the desired revision, test in the top-level repo, then com-
mit in the parent repository to record the new combination.
DELETING A SUBREPOSITORY
To remove a subrepository from the parent repository, delete its reference from .hgsub, then remove its files.
INTERACTION WITH MERCURIAL COMMANDS
add add does not recurse in subrepos unless -S/--subrepos is specified. However, if you specify the full path of a file in a subrepo,
it will be added even without -S/--subrepos specified. Git and Subversion subrepositories are currently silently ignored.
archive
archive does not recurse in subrepositories unless -S/--subrepos is specified.
commit commit creates a consistent snapshot of the state of the entire project and its subrepositories. If any subrepositories have been
modified, Mercurial will abort. Mercurial can be made to instead commit all modified subrepositories by specifying -S/--subrepos,
or setting "ui.commitsubrepos=True" in a configuration file (see hg help config). After there are no longer any modified subreposi-
tories, it records their state and finally commits it in the parent repository.
diff diff does not recurse in subrepos unless -S/--subrepos is specified. Changes are displayed as usual, on the subrepositories ele-
ments. Git and Subversion subrepositories are currently silently ignored.
forget forget currently only handles exact file matches in subrepos. Git and Subversion subrepositories are currently silently ignored.
incoming
incoming does not recurse in subrepos unless -S/--subrepos is specified. Git and Subversion subrepositories are currently silently
ignored.
outgoing
outgoing does not recurse in subrepos unless -S/--subrepos is specified. Git and Subversion subrepositories are currently silently
ignored.
pull pull is not recursive since it is not clear what to pull prior to running hg update. Listing and retrieving all subrepositories
changes referenced by the parent repository pulled changesets is expensive at best, impossible in the Subversion case.
push Mercurial will automatically push all subrepositories first when the parent repository is being pushed. This ensures new subreposi-
tory changes are available when referenced by top-level repositories. Push is a no-op for Subversion subrepositories.
status status does not recurse into subrepositories unless -S/--subrepos is specified. Subrepository changes are displayed as regular Mer-
curial changes on the subrepository elements. Subversion subrepositories are currently silently ignored.
update update restores the subrepos in the state they were originally committed in target changeset. If the recorded changeset is not
available in the current subrepository, Mercurial will pull it in first before updating. This means that updating can require net-
work access when using subrepositories.
REMAPPING SUBREPOSITORIES SOURCES
A subrepository source location may change during a project life, invalidating references stored in the parent repository history. To fix
this, rewriting rules can be defined in parent repository hgrc file or in Mercurial configuration. See the [subpaths] section in hgrc(5)
for more details.
TEMPLATE USAGE
Mercurial allows you to customize output of commands through templates. You can either pass in a template from the command line, via the
--template option, or select an existing template-style (--style).
You can customize output for any "log-like" command: log, outgoing, incoming, tip, parents, heads and glog.
Four styles are packaged with Mercurial: default (the style used when no explicit preference is passed), compact, changelog, and xml.
Usage:
$ hg log -r1 --style changelog
A template is a piece of text, with markup to invoke variable expansion:
$ hg log -r1 --template "{node}
"
b56ce7b07c52de7d5fd79fb89701ea538af65746
Strings in curly braces are called keywords. The availability of keywords depends on the exact context of the templater. These keywords are
usually available for templating a log-like command:
author String. The unmodified author of the changeset.
bisect String. The changeset bisection status.
bookmarks
List of strings. Any bookmarks associated with the changeset.
branch String. The name of the branch on which the changeset was committed.
branches
List of strings. The name of the branch on which the changeset was committed. Will be empty if the branch name was default.
children
List of strings. The children of the changeset.
date Date information. The date when the changeset was committed.
desc String. The text of the changeset description.
diffstat
String. Statistics of changes with the following format: "modified files: +added/-removed lines"
file_adds
List of strings. Files added by this changeset.
file_copies
List of strings. Files copied in this changeset with their sources.
file_copies_switch
List of strings. Like "file_copies" but displayed only if the --copied switch is set.
file_dels
List of strings. Files removed by this changeset.
file_mods
List of strings. Files modified by this changeset.
files List of strings. All files modified, added, or removed by this changeset.
latesttag
String. Most recent global tag in the ancestors of this changeset.
latesttagdistance
Integer. Longest path to the latest tag.
node String. The changeset identification hash, as a 40 hexadecimal digit string.
phase String. The changeset phase name.
phaseidx
Integer. The changeset phase index.
rev Integer. The repository-local changeset revision number.
tags List of strings. Any tags associated with the changeset.
The "date" keyword does not produce human-readable output. If you want to use a date in your output, you can use a filter to process it.
Filters are functions which return a string based on the input variable. Be sure to use the stringify filter first when you're applying a
string-input filter to a list-like input variable. You can also use a chain of filters to get the desired output:
$ hg tip --template "{date|isodate}
"
2008-08-21 18:22 +0000
List of filters:
addbreaks
Any text. Add an XHTML "<br />" tag before the end of every line except the last.
age Date. Returns a human-readable date/time difference between the given date/time and the current date/time.
basename
Any text. Treats the text as a path, and returns the last component of the path after splitting by the path separator (ignoring
trailing separators). For example, "foo/bar/baz" becomes "baz" and "foo/bar//" becomes "bar".
date Date. Returns a date in a Unix date format, including the timezone: "Mon Sep 04 15:13:13 2006 0700".
domain Any text. Finds the first string that looks like an email address, and extracts just the domain component. Example: User <user@exam-
ple.com> becomes example.com.
email Any text. Extracts the first string that looks like an email address. Example: User <user@example.com> becomes user@example.com.
emailuser
Any text. Returns the user portion of an email address.
escape Any text. Replaces the special XML/XHTML characters "&", "<" and ">" with XML entities.
fill68 Any text. Wraps the text to fit in 68 columns.
fill76 Any text. Wraps the text to fit in 76 columns.
firstline
Any text. Returns the first line of text.
hex Any text. Convert a binary Mercurial node identifier into its long hexadecimal representation.
hgdate Date. Returns the date as a pair of numbers: "1157407993 25200" (Unix timestamp, timezone offset).
isodate
Date. Returns the date in ISO 8601 format: "2009-08-18 13:00 +0200".
isodatesec
Date. Returns the date in ISO 8601 format, including seconds: "2009-08-18 13:00:13 +0200". See also the rfc3339date filter.
localdate
Date. Converts a date to local date.
nonempty
Any text. Returns '(none)' if the string is empty.
obfuscate
Any text. Returns the input text rendered as a sequence of XML entities.

URL PATHS
Valid URLs are of the form:
local/filesystem/path[#revision]
file://local/filesystem/path[#revision]
http://[user[:pass]@]host[:port]/[path][#revision]
https://[user[:pass]@]host[:port]/[path][#revision]
ssh://[user@]host[:port]/[path][#revision]
Paths in the local filesystem can either point to Mercurial repositories or to bundle files (as created by hg bundle or :hg:` incoming
--bundle`). See also hg help paths.
An optional identifier after # indicates a particular branch, tag, or changeset to use from the remote repository. See also hg help revi-
sions.
Some features, such as pushing to http:// and https:// URLs are only possible if the feature is explicitly enabled on the remote Mercurial
server.
Note that the security of HTTPS URLs depends on proper configuration of web.cacerts.
Some notes about using SSH with Mercurial:
o SSH requires an accessible shell account on the destination machine and a copy of hg in the remote path or specified with as remotecmd.
o path is relative to the remote user's home directory by default. Use an extra slash at the start of a path to specify an absolute path:
ssh://example.com//tmp/repository
o Mercurial doesn't use its own compression via SSH; the right thing to do is to configure it in your ~/.ssh/config, e.g.:
Host *.mylocalnetwork.example.com
Compression no
Host *
Compression yes
Alternatively specify "ssh -C" as your ssh command in your configuration file or with the --ssh command line option.
These URLs can all be stored in your configuration file with path aliases under the [paths] section like so:
[paths]
alias1 = URL1
alias2 = URL2
...
You can then use the alias for any command that uses a URL (for example hg pull alias1 will be treated as hg pull URL1).
Two path aliases are special because they are used as defaults when you do not provide the URL to a command:
default:
When you create a repository with hg clone, the clone command saves the location of the source repository as the new repository's
'default' path. This is then used when you omit path from push- and pull-like commands (including incoming and outgoing).
default-push:
The push command will look for a path named 'default-push', and prefer it over 'default' if both are defined.
EXTENSIONS
This section contains help for extensions that are distributed together with Mercurial. Help for other extensions is available in the help
system.
acl
hooks for controlling repository access
This hook makes it possible to allow or deny write access to given branches and paths of a repository when receiving incoming changesets
via pretxnchangegroup and pretxncommit.
The authorization is matched based on the local user name on the system where the hook runs, and not the committer of the original change-
set (since the latter is merely informative).
The acl hook is best used along with a restricted shell like hgsh, preventing authenticating users from doing anything other than pushing
or pulling. The hook is not safe to use if users have interactive shell access, as they can then disable the hook. Nor is it safe if remote
users share an account, because then there is no way to distinguish them.
The order in which access checks are performed is:
1. Deny list for branches (section acl.deny.branches)
2. Allow list for branches (section acl.allow.branches)
3. Deny list for paths (section acl.deny)
4. Allow list for paths (section acl.allow)
The allow and deny sections take key-value pairs.
Branch-based Access Control
Use the acl.deny.branches and acl.allow.branches sections to have branch-based access control. Keys in these sections can be either:
o a branch name, or
o an asterisk, to match any branch;
The corresponding values can be either:
o a comma-separated list containing users and groups, or
o an asterisk, to match anyone;
Path-based Access Control
Use the acl.deny and acl.allow sections to have path-based access control. Keys in these sections accept a subtree pattern (with a glob
syntax by default). The corresponding values follow the same syntax as the other sections above.
Groups
Group names must be prefixed with an @ symbol. Specifying a group name has the same effect as specifying all the users in that group.
You can define group members in the acl.groups section. If a group name is not defined there, and Mercurial is running under a Unix-like
system, the list of users will be taken from the OS. Otherwise, an exception will be raised.
Example Configuration
[hooks]
# Use this if you want to check access restrictions at commit time
pretxncommit.acl = python:hgext.acl.hook
# Use this if you want to check access restrictions for pull, push,
# bundle and serve.
pretxnchangegroup.acl = python:hgext.acl.hook
[acl]
# Allow or deny access for incoming changes only if their source is
# listed here, let them pass otherwise. Source is "serve" for all
# remote access (http or ssh), "push", "pull" or "bundle" when the
# related commands are run locally.
# Default: serve
sources = serve
[acl.deny.branches]
# Everyone is denied to the frozen branch:
frozen-branch = *
# A bad user is denied on all branches:
* = bad-user
[acl.allow.branches]
# A few users are allowed on branch-a:
branch-a = user-1, user-2, user-3
# Only one user is allowed on branch-b:
branch-b = user-1
# The super user is allowed on any branch:
* = super-user
# Everyone is allowed on branch-for-tests:
branch-for-tests = *
[acl.deny]
# This list is checked first. If a match is found, acl.allow is not
# checked. All users are granted access if acl.deny is not present.
# Format for both lists: glob pattern = user, ..., @group, ...
# To match everyone, use an asterisk for the user:
# my/glob/pattern = *
# user6 will not have write access to any file:
** = user6
# Group "hg-denied" will not have write access to any file:
** = @hg-denied
# Nobody will be able to change "DONT-TOUCH-THIS.txt", despite
# everyone being able to change all other files. See below.
src/main/resources/DONT-TOUCH-THIS.txt = *
[acl.allow]
# if acl.allow is not present, all users are allowed by default
# empty acl.allow = no users allowed
# User "doc_writer" has write access to any file under the "docs"
# folder:
docs/** = doc_writer
# User "jack" and group "designers" have write access to any file
# under the "images" folder:
images/** = jack, @designers
# Everyone (except for "user6" and "@hg-denied" - see acl.deny above)
# will have write access to any file under the "resources" folder
# (except for 1 file. See acl.deny):

bugzilla
hooks for integrating with the Bugzilla bug tracker
This hook extension adds comments on bugs in Bugzilla when changesets that refer to bugs by Bugzilla ID are seen. The comment is formatted
using the Mercurial template mechanism.
The bug references can optionally include an update for Bugzilla of the hours spent working on the bug. Bugs can also be marked fixed.
Three basic modes of access to Bugzilla are provided:
1. Access via the Bugzilla XMLRPC interface. Requires Bugzilla 3.4 or later.
2. Check data via the Bugzilla XMLRPC interface and submit bug change via email to Bugzilla email interface. Requires Bugzilla 3.4 or
later.
3. Writing directly to the Bugzilla database. Only Bugzilla installations using MySQL are supported. Requires Python MySQLdb.
Writing directly to the database is susceptible to schema changes, and relies on a Bugzilla contrib script to send out bug change notifica-
tion emails. This script runs as the user running Mercurial, must be run on the host with the Bugzilla install, and requires permission to
read Bugzilla configuration details and the necessary MySQL user and password to have full access rights to the Bugzilla database. For
these reasons this access mode is now considered deprecated, and will not be updated for new Bugzilla versions going forward. Only adding
comments is supported in this access mode.
Access via XMLRPC needs a Bugzilla username and password to be specified in the configuration. Comments are added under that username.
Since the configuration must be readable by all Mercurial users, it is recommended that the rights of that user are restricted in Bugzilla
to the minimum necessary to add comments. Marking bugs fixed requires Bugzilla 4.0 and later.
Access via XMLRPC/email uses XMLRPC to query Bugzilla, but sends email to the Bugzilla email interface to submit comments to bugs. The
From: address in the email is set to the email address of the Mercurial user, so the comment appears to come from the Mercurial user. In
the event that the Mercurial user email is not recognised by Bugzilla as a Bugzilla user, the email associated with the Bugzilla username
used to log into Bugzilla is used instead as the source of the comment. Marking bugs fixed works on all supported Bugzilla versions.
Configuration items common to all access modes:
bugzilla.version
This access type to use. Values recognised are:
xmlrpc
Bugzilla XMLRPC interface.
xmlrpc+email
Bugzilla XMLRPC and email interfaces.
3.0
MySQL access, Bugzilla 3.0 and later.
2.18
MySQL access, Bugzilla 2.18 and up to but not including 3.0.
2.16
MySQL access, Bugzilla 2.16 and up to but not including 2.18.
bugzilla.regexp
Regular expression to match bug IDs for update in changeset commit message. It must contain one "()" named group <ids> containing
the bug IDs separated by non-digit characters. It may also contain a named group <hours> with a floating-point number giving the
hours worked on the bug. If no named groups are present, the first "()" group is assumed to contain the bug IDs, and work time is
not updated. The default expression matches Bug 1234, Bug no. 1234, Bug number 1234, Bugs 1234,5678, Bug 1234 and 5678 and varia-
tions thereof, followed by an hours number prefixed by h or hours, e.g. hours 1.5. Matching is case insensitive.
bugzilla.fixregexp
Regular expression to match bug IDs for marking fixed in changeset commit message. This must contain a "()" named group <ids>` con-
taining the bug IDs separated by non-digit characters. It may also contain a named group ``<hours> with a floating-point number giv-
ing the hours worked on the bug. If no named groups are present, the first "()" group is assumed to contain the bug IDs, and work
time is not updated. The default expression matches Fixes 1234, Fixes bug 1234, Fixes bugs 1234,5678, Fixes 1234 and 5678 and varia-
tions thereof, followed by an hours number prefixed by h or hours, e.g. hours 1.5. Matching is case insensitive.
bugzilla.fixstatus
The status to set a bug to when marking fixed. Default RESOLVED.
bugzilla.fixresolution
The resolution to set a bug to when marking fixed. Default FIXED.
bugzilla.style
The style file to use when formatting comments.
bugzilla.template
Template to use when formatting comments. Overrides style if specified. In addition to the usual Mercurial keywords, the extension
specifies:
{bug}
The Bugzilla bug ID.
{root}
The full pathname of the Mercurial repository.
{webroot}
Stripped pathname of the Mercurial repository.
{hgweb}
Base URL for browsing Mercurial repositories.
Default changeset {node|short} in repo {root} refers to bug {bug}.
details:
{desc|tabindent}
bugzilla.strip
The number of path separator characters to strip from the front of the Mercurial repository path ({root} in templates) to produce
{webroot}. For example, a repository with {root} /var/local/my-project with a strip of 2 gives a value for {webroot} of my-project.
Default 0.
web.baseurl
Base URL for browsing Mercurial repositories. Referenced from templates as {hgweb}.
Configuration items common to XMLRPC+email and MySQL access modes:
bugzilla.usermap
Path of file containing Mercurial committer email to Bugzilla user email mappings. If specified, the file should contain one mapping
per line:
committer = Bugzilla user
See also the [usermap] section.
The [usermap] section is used to specify mappings of Mercurial committer email to Bugzilla user email. See also bugzilla.usermap. Contains
entries of the form committer = Bugzilla user.
XMLRPC access mode configuration:
bugzilla.bzurl
The base URL for the Bugzilla installation. Default http://localhost/bugzilla.
bugzilla.user
The username to use to log into Bugzilla via XMLRPC. Default bugs.
bugzilla.password
The password for Bugzilla login.
XMLRPC+email access mode uses the XMLRPC access mode configuration items, and also:
bugzilla.bzemail
The Bugzilla email address.
In addition, the Mercurial email settings must be configured. See the documentation in hgrc(5), sections [email] and [smtp].
MySQL access mode configuration:
bugzilla.host
Hostname of the MySQL server holding the Bugzilla database. Default localhost.
bugzilla.db
Name of the Bugzilla database in MySQL. Default bugs.
bugzilla.user
Username to use to access MySQL server. Default bugs.
bugzilla.password
Password to use to access MySQL server.
bugzilla.timeout
Database connection timeout (seconds). Default 5.
bugzilla.bzuser
Fallback Bugzilla user name to record comments with, if changeset committer cannot be found as a Bugzilla user.
bugzilla.bzdir
Bugzilla install directory. Used by default notify. Default /var/www/html/bugzilla.
bugzilla.notify
The command to run to get Bugzilla to send bug change notification emails. Substitutes from a map with 3 keys, bzdir, id (bug id)
and user (committer bugzilla email). Default depends on version; from 2.18 it is "cd %(bzdir)s && perl -T contrib/sendbugmail.pl
%(id)s %(user)s".

children
command to display child changesets
Commands
children
hg children [-r REV] [FILE]
Print the children of the working directory's revisions. If a revision is given via -r/--rev, the children of that revision will be
printed. If a file argument is given, revision in which the file was last changed (after the working directory revision or the argument to
--rev if given) is printed.
Options:
-r, --rev
show children of the specified revision
--style
display using template map file
--template
display with template
churn
command to display statistics about repository history
Commands
churn
hg churn [-d DATE] [-r REV] [--aliases FILE] [FILE]
This command will display a histogram representing the number of changed lines or revisions, grouped according to the given template. The
default template will group changes by author. The --dateformat option may be used to group the results by date instead.
Statistics are based on the number of changed lines, or alternatively the number of matching revisions if the --changesets option is speci-
fied.
Examples:
# display count of changed lines for every committer
hg churn -t '{author|email}'
# display daily activity graph
hg churn -f '%H' -s -c
# display activity of developers by month
hg churn -f '%Y-%m' -s -c
# display count of lines changed in every year
hg churn -f '%Y' -s
It is possible to map alternate email addresses to a main address by providing a file using the following format:
<alias email> = <actual email>
Such a file may be specified with the --aliases option, otherwise a .hgchurn file will be looked for in the working directory root.
Options:
-r, --rev
count rate for the specified revision or range
-d, --date
count rate for revisions matching date spec
-t, --template
template to group changesets (default: {author|email})
-f, --dateformat
strftime-compatible format for grouping by date
-c, --changesets
count rate by number of changesets
-s, --sort
sort by key (default: sort by count)
--diffstat
display added/removed lines separately
--aliases
file with email aliases
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
color
colorize output from some commands
This extension modifies the status and resolve commands to add color to their output to reflect file status, the qseries command to add
color to reflect patch status (applied, unapplied, missing), and to diff-related commands to highlight additions, removals, diff headers,
and trailing whitespace.
Other effects in addition to color, like bold and underlined text, are also available. By default, the terminfo database is used to find
the terminal codes used to change color and effect. If terminfo is not available, then effects are rendered with the ECMA-48 SGR control
function (aka ANSI escape codes).
Default effects may be overridden from your configuration file:
[color]
status.modified = blue bold underline red_background
status.added = green bold
status.removed = red bold blue_background
status.deleted = cyan bold underline
status.unknown = magenta bold underline
status.ignored = black bold
# 'none' turns off all effects
status.clean = none
status.copied = none
qseries.applied = blue bold underline
qseries.unapplied = black bold
qseries.missing = red bold
diff.diffline = bold
diff.extended = cyan bold
diff.file_a = red bold
diff.file_b = green bold
diff.hunk = magenta
diff.deleted = red
diff.inserted = green
diff.changed = white
diff.trailingwhitespace = bold red_background
resolve.unresolved = red bold
resolve.resolved = green bold
bookmarks.current = green
branches.active = none
branches.closed = black bold
branches.current = green
branches.inactive = none
tags.normal = green
tags.local = black bold
The available effects in terminfo mode are 'blink', 'bold', 'dim', 'inverse', 'invisible', 'italic', 'standout', and 'underline'; in
ECMA-48 mode, the options are 'bold', 'inverse', 'italic', and 'underline'. How each is rendered depends on the terminal emulator. Some
may not be available for a given terminal type, and will be silently ignored.
Note that on some systems, terminfo mode may cause problems when using color with the pager extension and less -R. less with the -R option
will only display ECMA-48 color codes, and terminfo mode may sometimes emit codes that less doesn't understand. You can work around this by
either using ansi mode (or auto mode), or by using less -r (which will pass through all terminal control codes, not just color control
codes).
Because there are only eight standard colors, this module allows you to define color names for other color slots which might be available
for your terminal type, assuming terminfo mode. For instance:
color.brightblue = 12
color.pink = 207
color.orange = 202
to set 'brightblue' to color slot 12 (useful for 16 color terminals that have brighter colors defined in the upper eight) and, 'pink' and
'orange' to colors in 256-color xterm's default color cube. These defined colors may then be used as any of the pre-defined eight, includ-
ing appending '_background' to set the background to that color.
By default, the color extension will use ANSI mode (or win32 mode on Windows) if it detects a terminal. To override auto mode (to enable
terminfo mode, for example), set the following configuration option:
[color]
mode = terminfo
Any value other than 'ansi', 'win32', 'terminfo', or 'auto' will disable color.
convert
import revisions from foreign VCS repositories into Mercurial
Commands
convert
hg convert [OPTION]... SOURCE [DEST [REVMAP]]
Accepted source formats [identifiers]:
o Mercurial [hg]
o CVS [cvs]
o Darcs [darcs]
o git [git]
o Subversion [svn]
o Monotone [mtn]
o GNU Arch [gnuarch]
o Bazaar [bzr]
o Perforce [p4]
Accepted destination formats [identifiers]:
o Mercurial [hg]
o Subversion [svn] (history on branches is not preserved)
If no revision is given, all revisions will be converted. Otherwise, convert will only import up to the named revision (given in a format
understood by the source).
If no destination directory name is specified, it defaults to the basename of the source with -hg appended. If the destination repository
doesn't exist, it will be created.
By default, all sources except Mercurial will use --branchsort. Mercurial uses --sourcesort to preserve original revision numbers order.
Sort modes have the following effects:
--branchsort
convert from parent to child revision when possible, which means branches are usually converted one after the other. It generates
more compact repositories.
--datesort
sort revisions by date. Converted repositories have good-looking changelogs but are often an order of magnitude larger than the same
ones generated by --branchsort.
--sourcesort
try to preserve source revisions order, only supported by Mercurial sources.
If REVMAP isn't given, it will be put in a default location (<dest>/.hg/shamap by default). The REVMAP is a simple text file that maps each
source commit ID to the destination ID for that revision, like so:
<source ID> <destination ID>
If the file doesn't exist, it's automatically created. It's updated on each commit copied, so hg convert can be interrupted and can be run
repeatedly to copy new commits.
The authormap is a simple text file that maps each source commit author to a destination commit author. It is handy for source SCMs that
use unix logins to identify authors (eg: CVS). One line per author mapping and the line format is:
source author = destination author
Empty lines and lines starting with a # are ignored.
The filemap is a file that allows filtering and remapping of files and directories. Each line can contain one of the following directives:
include path/to/file-or-dir
exclude path/to/file-or-dir
rename path/to/source path/to/destination
Comment lines start with #. A specified path matches if it equals the full relative name of a file or one of its parent directories. The
include or exclude directive with the longest matching path applies, so line order does not matter.
The include directive causes a file, or all files under a directory, to be included in the destination repository, and the exclusion of all
other files and directories not explicitly included. The exclude directive causes files or directories to be omitted. The rename directive
renames a file or directory if it is converted. To rename from a subdirectory into the root of the repository, use . as the path to rename
to.
The splicemap is a file that allows insertion of synthetic history, letting you specify the parents of a revision. This is useful if you
want to e.g. give a Subversion merge two parents, or graft two disconnected series of history together. Each entry contains a key, followed
by a space, followed by one or two comma-separated values:
key parent1, parent2
The key is the revision ID in the source revision control system whose parents should be modified (same format as a key in .hg/shamap). The
values are the revision IDs (in either the source or destination revision control system) that should be used as the new parents for that
node. For example, if you have merged "release-1.0" into "trunk", then you should specify the revision on "trunk" as the first parent and
the one on the "release-1.0" branch as the second.
The branchmap is a file that allows you to rename a branch when it is being brought in from whatever external repository. When used in con-
junction with a splicemap, it allows for a powerful combination to help fix even the most badly mismanaged repositories and turn them into
nicely structured Mercurial repositories. The branchmap contains lines of the form:
original_branch_name new_branch_name
where "original_branch_name" is the name of the branch in the source repository, and "new_branch_name" is the name of the branch is the
destination repository. No whitespace is allowed in the branch names. This can be used to (for instance) move code in one repository from
"default" to a named branch.
Mercurial Source
The Mercurial source recognizes the following configuration options, which you can set on the command line with --config:
convert.hg.ignoreerrors
ignore integrity errors when reading. Use it to fix Mercurial repositories with missing revlogs, by converting from and to Mercu-
rial. Default is False.
convert.hg.saverev
store original revision ID in changeset (forces target IDs to change). It takes a boolean argument and defaults to False.
convert.hg.startrev
convert start revision and its descendants. It takes a hg revision identifier and defaults to 0.
CVS Source
CVS source will use a sandbox (i.e. a checked-out copy) from CVS to indicate the starting point of what will be converted. Direct access to
the repository files is not needed, unless of course the repository is :local:. The conversion uses the top level directory in the sandbox
to find the CVS repository, and then uses CVS rlog commands to find files to convert. This means that unless a filemap is given, all files
under the starting directory will be converted, and that any directory reorganization in the CVS sandbox is ignored.
The following options can be used with --config:
convert.cvsps.cache
Set to False to disable remote log caching, for testing and debugging purposes. Default is True.
convert.cvsps.fuzz
Specify the maximum time (in seconds) that is allowed between commits with identical user and log message in a single changeset.
When very large files were checked in as part of a changeset then the default may not be long enough. The default is 60.
convert.cvsps.mergeto
Specify a regular expression to which commit log messages are matched. If a match occurs, then the conversion process will insert a
dummy revision merging the branch on which this log message occurs to the branch indicated in the regex. Default is {{mergetobranch
([-w]+)}}
convert.cvsps.mergefrom
Specify a regular expression to which commit log messages are matched. If a match occurs, then the conversion process will add the
most recent revision on the branch indicated in the regex as the second parent of the changeset. Default is {{mergefrombranch
([-w]+)}}
hook.cvslog
Specify a Python function to be called at the end of gathering the CVS log. The function is passed a list with the log entries, and
can modify the entries in-place, or add or delete them.
hook.cvschangesets
Specify a Python function to be called after the changesets are calculated from the the CVS log. The function is passed a list with
the changeset entries, and can modify the changesets in-place, or add or delete them.
An additional "debugcvsps" Mercurial command allows the builtin changeset merging code to be run without doing a conversion. Its parameters
and output are similar to that of cvsps 2.1. Please see the command help for more details.
Subversion Source
Subversion source detects classical trunk/branches/tags layouts. By default, the supplied svn://repo/path/ source URL is converted as a
single branch. If svn://repo/path/trunk exists it replaces the default branch. If svn://repo/path/branches exists, its subdirectories are
listed as possible branches. If svn://repo/path/tags exists, it is looked for tags referencing converted branches. Default trunk, branches
and tags values can be overridden with following options. Set them to paths relative to the source URL, or leave them blank to disable auto
detection.
The following options can be set with --config:
convert.svn.branches
specify the directory containing branches. The default is branches.
convert.svn.tags
specify the directory containing tags. The default is tags.
convert.svn.trunk
specify the name of the trunk branch. The default is trunk.
Source history can be retrieved starting at a specific revision, instead of being integrally converted. Only single branch conversions are
supported.
convert.svn.startrev
specify start Subversion revision number. The default is 0.
Perforce Source
The Perforce (P4) importer can be given a p4 depot path or a client specification as source. It will convert all files in the source to a
flat Mercurial repository, ignoring labels, branches and integrations. Note that when a depot path is given you then usually should specify
a target directory, because otherwise the target may be named ...-hg.
It is possible to limit the amount of source history to be converted by specifying an initial Perforce revision:
convert.p4.startrev
specify initial Perforce revision (a Perforce changelist number).
Mercurial Destination
The following options are supported:
convert.hg.clonebranches
dispatch source branches in separate clones. The default is False.
convert.hg.tagsbranch
branch name for tag revisions, defaults to default.
convert.hg.usebranchnames
preserve branch names. The default is True.
Options:
--authors
username mapping filename (DEPRECATED, use --authormap instead)
-s, --source-type
source repository type
-d, --dest-type
destination repository type
-r, --rev
import up to target revision REV
-A, --authormap
remap usernames using this file
--filemap
remap file names using contents of file
--splicemap
splice synthesized history into place
--branchmap
change branch names while converting
--branchsort
try to sort changesets by branches
--datesort
try to sort changesets by date
--sourcesort
preserve source changesets order
eol
automatically manage newlines in repository files
This extension allows you to manage the type of line endings (CRLF or LF) that are used in the repository and in the local working direc-
tory. That way you can get CRLF line endings on Windows and LF on Unix/Mac, thereby letting everybody use their OS native line endings.
The extension reads its configuration from a versioned .hgeol configuration file found in the root of the working copy. The .hgeol file use
the same syntax as all other Mercurial configuration files. It uses two sections, [patterns] and [repository].
The [patterns] section specifies how line endings should be converted between the working copy and the repository. The format is specified
by a file pattern. The first match is used, so put more specific patterns first. The available line endings are LF, CRLF, and BIN.
Files with the declared format of CRLF or LF are always checked out and stored in the repository in that format and files declared to be
binary (BIN) are left unchanged. Additionally, native is an alias for checking out in the platform's default line ending: LF on Unix
(including Mac OS X) and CRLF on Windows. Note that BIN (do nothing to line endings) is Mercurial's default behaviour; it is only needed if
you need to override a later, more general pattern.
The optional [repository] section specifies the line endings to use for files stored in the repository. It has a single setting, native,
which determines the storage line endings for files declared as native in the [patterns] section. It can be set to LF or CRLF. The default
is LF. For example, this means that on Windows, files configured as native (CRLF by default) will be converted to LF when stored in the
repository. Files declared as LF, CRLF, or BIN in the [patterns] section are always stored as-is in the repository.
Example versioned .hgeol file:
[patterns]
**.py = native
**.vcproj = CRLF
**.txt = native
Makefile = LF
**.jpg = BIN
[repository]
native = LF
Note The rules will first apply when files are touched in the working copy, e.g. by updating to null and back to tip to touch all files.
The extension uses an optional [eol] section read from both the normal Mercurial configuration files and the .hgeol file, with the latter
overriding the former. You can use that section to control the overall behavior. There are three settings:
o eol.native (default os.linesep) can be set to LF or CRLF to override the default interpretation of native for checkout. This can be used
with hg archive on Unix, say, to generate an archive where files have line endings for Windows.
o eol.only-consistent (default True) can be set to False to make the extension convert files with inconsistent EOLs. Inconsistent means
that there is both CRLF and LF present in the file. Such files are normally not touched under the assumption that they have mixed EOLs
on purpose.
o eol.fix-trailing-newline (default False) can be set to True to ensure that converted files end with a EOL character (either
or
as
per the configured patterns).
The extension provides cleverencode: and cleverdecode: filters like the deprecated win32text extension does. This means that you can dis-
able win32text and enable eol and your filters will still work. You only need to these filters until you have prepared a .hgeol file.
The win32text.forbid* hooks provided by the win32text extension have been unified into a single hook named eol.checkheadshook. The hook
will lookup the expected line endings from the .hgeol file, which means you must migrate to a .hgeol file first before using the hook.
eol.checkheadshook only checks heads, intermediate invalid revisions will be pushed. To forbid them completely, use the eol.checkallhook
hook. These hooks are best used as pretxnchangegroup hooks.
See hg help patterns for more information about the glob patterns used.
extdiff
command to allow external programs to compare revisions
The extdiff Mercurial extension allows you to use external programs to compare revisions, or revision with working directory. The external
diff programs are called with a configurable set of options and two non-option arguments: paths to directories containing snapshots of
files to compare.
The extdiff extension also allows you to configure new diff commands, so you do not need to type hg extdiff -p kdiff3 always.
[extdiff]
# add new command that runs GNU diff(1) in 'context diff' mode
cdiff = gdiff -Nprc5
## or the old way:
#cmd.cdiff = gdiff
#opts.cdiff = -Nprc5
# add new command called vdiff, runs kdiff3
vdiff = kdiff3
# add new command called meld, runs meld (no need to name twice)
meld =
# add new command called vimdiff, runs gvimdiff with DirDiff plugin
# (see http://www.vim.org/scripts/script.php?script_id=102) Non
# English user, be sure to put "let g:DirDiffDynamicDiffText = 1" in
# your .vimrc
vimdiff = gvim -f "+next"
"+execute 'DirDiff' fnameescape(argv(0)) fnameescape(argv(1))"
Tool arguments can include variables that are expanded at runtime:
$parent1, $plabel1 - filename, descriptive label of first parent
$child, $clabel - filename, descriptive label of child revision
$parent2, $plabel2 - filename, descriptive label of second parent
$root - repository root
$parent is an alias for $parent1.
The extdiff extension will look in your [diff-tools] and [merge-tools] sections for diff tool arguments, when none are specified in [extd-
iff].
[extdiff]
kdiff3 =
[diff-tools]
kdiff3.diffargs=--L1 '$plabel1' --L2 '$clabel' $parent $child
You can use -I/-X and list of file or directory names like normal hg diff command. The extdiff extension makes snapshots of only needed
files, so running the external diff program will actually be pretty fast (at least faster than having to compare the entire tree).
Commands
extdiff
hg extdiff [OPT]... [FILE]...
Show differences between revisions for the specified files, using an external program. The default program used is diff, with default
options "-Npru".
To select a different program, use the -p/--program option. The program will be passed the names of two directories to compare. To pass
additional options to the program, use -o/--option. These will be passed before the names of the directories to compare.
When two revision arguments are given, then changes are shown between those revisions. If only one revision is specified then that revision
is compared to the working directory, and, when no revisions are specified, the working directory files are compared to its parent.
Options:
-p, --program
comparison program to run
-o, --option
pass option to comparison program
-r, --rev
revision
-c, --change
change made by revision
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
factotum
http authentication with factotum
This extension allows the factotum(4) facility on Plan 9 from Bell Labs platforms to provide authentication information for HTTP access.
Configuration entries specified in the auth section as well as authentication information provided in the repository URL are fully sup-
ported. If no prefix is specified, a value of "*" will be assumed.
By default, keys are specified as:
proto=pass service=hg prefix=<prefix> user=<username> !password=<password>
If the factotum extension is unable to read the required key, one will be requested interactively.
A configuration section is available to customize runtime behavior. By default, these entries are:
[factotum]
executable = /bin/auth/factotum
mountpoint = /mnt/factotum
service = hg
The executable entry defines the full path to the factotum binary. The mountpoint entry defines the path to the factotum file service.
Lastly, the service entry controls the service name used when reading keys.
fetch
pull, update and merge in one command
Commands
fetch
hg fetch [SOURCE]
This finds all changes from the repository at the specified path or URL and adds them to the local repository.
If the pulled changes add a new branch head, the head is automatically merged, and the result of the merge is committed. Otherwise, the
working directory is updated to include the new changes.
When a merge is needed, the working directory is first updated to the newly pulled changes. Local changes are then merged into the pulled
changes. To switch the merge order, use --switch-parent.
See hg help dates for a list of formats valid for -d/--date.
Returns 0 on success.
Options:
-r, --rev
a specific revision you would like to pull
-e, --edit
edit commit message
--force-editor

hgcia
hooks for integrating with the CIA.vc notification service
This is meant to be run as a changegroup or incoming hook. To configure it, set the following options in your hgrc:
[cia]
# your registered CIA user name
user = foo
# the name of the project in CIA
project = foo
# the module (subproject) (optional)
#module = foo
# Append a diffstat to the log message (optional)
#diffstat = False
# Template to use for log messages (optional)
#template = {desc}
{baseurl}{webroot}/rev/{node}-- {diffstat}
# Style to use (optional)
#style = foo
# The URL of the CIA notification service (optional)

# mailto:cia@cia.vc
# Make sure to set email.from if you do this.
#url = http://cia.vc/
# print message instead of sending it (optional)
#test = False

[web]
# If you want hyperlinks (optional)
baseurl = http://server/path/to/repo
hgk
browse the repository in a graphical way
The hgk extension allows browsing the history of a repository in a graphical way. It requires Tcl/Tk version 8.4 or later. (Tcl/Tk is not
distributed with Mercurial.)
hgk consists of two parts: a Tcl script that does the displaying and querying of information, and an extension to Mercurial named hgk.py,
which provides hooks for hgk to get information. hgk can be found in the contrib directory, and the extension is shipped in the hgext
repository, and needs to be enabled.
The hg view command will launch the hgk Tcl script. For this command to work, hgk must be in your search path. Alternately, you can specify
the path to hgk in your configuration file:
[hgk]
path=/location/of/hgk
hgk can make use of the extdiff extension to visualize revisions. Assuming you had already configured extdiff vdiff command, just add:
[hgk]
vdiff=vdiff
Revisions context menu will now display additional entries to fire vdiff on hovered and selected revisions.
Commands
view
hg view [-l LIMIT] [REVRANGE]
start interactive history viewer
Options:
-l, --limit
limit number of changes displayed
highlight
syntax highlighting for hgweb (requires Pygments)
It depends on the Pygments syntax highlighting library: http://pygments.org/
There is a single configuration option:
[web]
pygments_style = <style>
The default is 'colorful'.
inotify
accelerate status report using Linux's inotify service
Commands
inserve
hg inserve [OPTION]...
start an inotify server for this repository
Options:
-d, --daemon
run server in background
--daemon-pipefds
used internally by daemon mode
-t, --idle-timeout
minutes to sit idle before exiting
--pid-file
name of file to write process ID to
interhg
expand expressions into changelog and summaries
This extension allows the use of a special syntax in summaries, which will be automatically expanded into links or any other arbitrary
expression, much like InterWiki does.
A few example patterns (link to bug tracking, etc.) that may be used in your hgrc:
[interhg]
issues = s!issue(d+)!<a href="http://bts/issue1">issue1</a>!
bugzilla = s!((?:bug|b=|(?=#?d{4,}))(?:s*#?)(d+))!<a..=2">1</a>!i
boldify = s!(^|s)#(d+)! <b>#2</b>!
keyword
expand keywords in tracked files
This extension expands RCS/CVS-like or self-customized $Keywords$ in tracked text files selected by your configuration.
Keywords are only expanded in local repositories and not stored in the change history. The mechanism can be regarded as a convenience for
the current user or for archive distribution.
Keywords expand to the changeset data pertaining to the latest change relative to the working directory parent of each file.
Configuration is done in the [keyword], [keywordset] and [keywordmaps] sections of hgrc files.
Example:
[keyword]
# expand keywords in every python file except those matching "x*"
**.py =
x* = ignore
[keywordset]
# prefer svn- over cvs-like default keywordmaps
svn = True
Note The more specific you are in your filename patterns the less you lose speed in huge repositories.
For [keywordmaps] template mapping and expansion demonstration and control run hg kwdemo. See hg help templates for a list of available
templates and filters.
Three additional date template filters are provided:
utcdate
"2006/09/18 15:13:13"
svnutcdate
"2006-09-18 15:13:13Z"
svnisodate
"2006-09-18 08:13:13 -700 (Mon, 18 Sep 2006)"
The default template mappings (view with hg kwdemo -d) can be replaced with customized keywords and templates. Again, run hg kwdemo to con-
trol the results of your configuration changes.
Before changing/disabling active keywords, you must run hg kwshrink to avoid storing expanded keywords in the change history.
To force expansion after enabling it, or a configuration change, run hg kwexpand.
Expansions spanning more than one line and incremental expansions, like CVS' $Log$, are not supported. A keyword template map "Log =
{desc}" expands to the first line of the changeset description.
Commands
kwdemo
hg kwdemo [-d] [-f RCFILE] [TEMPLATEMAP]...
Show current, custom, or default keyword template maps and their expansions.
Extend the current configuration by specifying maps as arguments and using -f/--rcfile to source an external hgrc file.
Use -d/--default to disable current configuration.
See hg help templates for information on templates and filters.
Options:
-d, --default
show default keyword template maps
-f, --rcfile
read maps from rcfile
kwexpand
hg kwexpand [OPTION]... [FILE]...
Run after (re)enabling keyword expansion.
kwexpand refuses to run if given files contain local changes.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
kwfiles
hg kwfiles [OPTION]... [FILE]...
List which files in the working directory are matched by the [keyword] configuration patterns.
Useful to prevent inadvertent keyword expansion and to speed up execution by including only files that are actual candidates for expansion.
See hg help keyword on how to construct patterns both for inclusion and exclusion of files.
With -A/--all and -v/--verbose the codes used to show the status of files are:
K = keyword expansion candidate
k = keyword expansion candidate (not tracked)
I = ignored
i = ignored (not tracked)
Options:
-A, --all
show keyword status flags of all files
-i, --ignore
show files excluded from expansion
-u, --unknown
only show unknown (not tracked) files
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
kwshrink
hg kwshrink [OPTION]... [FILE]...
Must be run before changing/disabling active keywords.
kwshrink refuses to run if given files contain local changes.
Options:
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
largefiles
track large binary files
Large binary files tend to be not very compressible, not very diffable, and not at all mergeable. Such files are not handled efficiently by
Mercurial's storage format (revlog), which is based on compressed binary deltas; storing large binary files as regular Mercurial files
wastes bandwidth and disk space and increases Mercurial's memory usage. The largefiles extension addresses these problems by adding a cen-
tralized client-server layer on top of Mercurial: largefiles live in a central store out on the network somewhere, and you only fetch the
revisions that you need when you need them.
largefiles works by maintaining a "standin file" in .hglf/ for each largefile. The standins are small (41 bytes: an SHA-1 hash plus new-
line) and are tracked by Mercurial. Largefile revisions are identified by the SHA-1 hash of their contents, which is written to the
standin. largefiles uses that revision ID to get/put largefile revisions from/to the central store. This saves both disk space and band-
width, since you don't need to retrieve all historical revisions of large files when you clone or pull.
To start a new repository or add new large binary files, just add --large to your hg add command. For example:
$ dd if=/dev/urandom of=randomdata count=2000
$ hg add --large randomdata
$ hg commit -m 'add randomdata as a largefile'
When you push a changeset that adds/modifies largefiles to a remote repository, its largefile revisions will be uploaded along with it.
Note that the remote Mercurial must also have the largefiles extension enabled for this to work.
When you pull a changeset that affects largefiles from a remote repository, Mercurial behaves as normal. However, when you update to such a
revision, any largefiles needed by that revision are downloaded and cached (if they have never been downloaded before). This means that
network access may be required to update to changesets you have not previously updated to.
If you already have large files tracked by Mercurial without the largefiles extension, you will need to convert your repository in order to
benefit from largefiles. This is done with the hg lfconvert command:
$ hg lfconvert --size 10 oldrepo newrepo
In repositories that already have largefiles in them, any new file over 10MB will automatically be added as a largefile. To change this
threshold, set largefiles.minsize in your Mercurial config file to the minimum size in megabytes to track as a largefile, or use the
--lfsize option to the add command (also in megabytes):
[largefiles]
minsize = 2
$ hg add --lfsize 2
The largefiles.patterns config option allows you to specify a list of filename patterns (see hg help patterns) that should always be
tracked as largefiles:
[largefiles]
patterns =
*.jpg
re:.*.(png|bmp)$
library.zip
content/audio/*
Files that match one of these patterns will be added as largefiles regardless of their size.
The largefiles.minsize and largefiles.patterns config options will be ignored for any repositories not already containing a largefile. To
add the first largefile to a repository, you must explicitly do so with the --large flag passed to the hg add command.
Commands
lfconvert
hg lfconvert SOURCE DEST [FILE ...]
Convert repository SOURCE to a new repository DEST, identical to SOURCE except that certain files will be converted as largefiles: specifi-
cally, any file that matches any PATTERN or whose size is above the minimum size threshold is converted as a largefile. The size used to
determine whether or not to track a file as a largefile is the size of the first version of the file. The minimum size can be specified
either with --size or in configuration as largefiles.size.
After running this command you will need to make sure that largefiles is enabled anywhere you intend to push the new repository.
Use --to-normal to convert largefiles back to normal files; after this, the DEST repository can be used without largefiles at all.
Options:
-s, --size
minimum size (MB) for files to be converted as largefiles
--to-normal
convert from a largefiles repo to a normal repo
mq
manage a stack of patches
This extension lets you work with a stack of patches in a Mercurial repository. It manages two stacks of patches - all known patches, and
applied patches (subset of known patches).
Known patches are represented as patch files in the .hg/patches directory. Applied patches are both patch files and changesets.
Common tasks (use hg help command for more details):
create new patch qnew
import existing patch qimport
print patch series qseries
print applied patches qapplied
add known patch to applied stack qpush
remove patch from applied stack qpop
refresh contents of top applied patch qrefresh
By default, mq will automatically use git patches when required to avoid losing file mode changes, copy records, binary files or empty
files creations or deletions. This behaviour can be configured with:
[mq]
git = auto/keep/yes/no
If set to 'keep', mq will obey the [diff] section configuration while preserving existing git patches upon qrefresh. If set to 'yes' or
'no', mq will override the [diff] section and always generate git or regular patches, possibly losing data in the second case.
It may be desirable for mq changesets to be kept in the secret phase (see hg help phases), which can be enabled with the following setting:
[mq]
secret = True
You will by default be managing a patch queue named "patches". You can create other, independent patch queues with the hg qqueue command.
Commands
qapplied
hg qapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --last
show only the preceding applied patch
-s, --summary
print first line of patch header
qclone
hg qclone [OPTION]... SOURCE [DEST]
If source is local, destination will have no patches applied. If source is remote, this command can not check if patches are applied in
source, so cannot guarantee that patches are not applied in destination. If you clone remote repository, be sure before that it has no
patches applied.
Source patch repository is looked for in <src>/.hg/patches by default. Use -p <url> to change.
The patch directory must be a nested Mercurial repository, as would be created by hg init --mq.
Return 0 on success.
Options:
--pull use pull protocol to copy metadata
-U, --noupdate
do not update the new working directories
--uncompressed
use uncompressed transfer (fast over LAN)
-p, --patches
location of source patch repository
-e, --ssh
specify ssh command to use
--remotecmd
specify hg command to run on the remote side
--insecure
do not verify server certificate (ignoring web.cacerts config)
qcommit
hg qcommit [OPTION]... [FILE]...
This command is deprecated; use hg commit --mq instead.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch as closed, hiding it from the branch list
--amend
amend the parent of the working dir
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message

-u, --user
record the specified user as committer
-S, --subrepos
recurse into subrepositories
aliases: qci
qdelete
hg qdelete [-k] [PATCH]...
The patches must not be applied, and at least one patch is required. Exact patch identifiers must be given. With -k/--keep, the patch files
are preserved in the patch directory.
To stop managing a patch and move it into permanent history, use the hg qfinish command.
Options:
-k, --keep
keep patch file
-r, --rev
stop managing a revision (DEPRECATED)
aliases: qremove qrm
qdiff
hg qdiff [OPTION]... [FILE]...
Shows a diff which includes the current patch as well as any changes which have been made in the working directory since the last refresh
(thus showing what the current patch would become after a qrefresh).
Use hg diff if you only want to see the changes made since the last qrefresh, or hg export qtip if you want to see changes made by the cur-
rent patch without including changes made since the qrefresh.
Returns 0 on success.
Options:
-a, --text
treat all files as text
-g, --git
use git extended diff format
--nodates
omit dates from diff headers
-p, --show-function
show which function each change is in
--reverse
produce a diff that undoes the changes
-w, --ignore-all-space

-b, --ignore-space-change
ignore changes in the amount of white space
-B, --ignore-blank-lines
ignore changes whose lines are all blank
-U, --unified
number of lines of context to show
--stat output diffstat-style summary of changes
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
qfinish
hg qfinish [-a] [REV]...
Finishes the specified revisions (corresponding to applied patches) by moving them out of mq control into regular repository history.
Accepts a revision range or the -a/--applied option. If --applied is specified, all applied mq revisions are removed from mq control. Oth-
erwise, the given revisions must be at the base of the stack of applied patches.
This can be especially useful if your changes have been applied to an upstream repository, or if you are about to push your changes to
upstream.
Returns 0 on success.
Options:
-a, --applied
finish all applied changesets
qfold
hg qfold [-e] [-k] [-m TEXT] [-l FILE] PATCH...
Patches must not yet be applied. Each patch will be successively applied to the current patch in the order given. If all the patches apply
successfully, the current patch will be refreshed with the new cumulative patch, and the folded patches will be deleted. With -k/--keep,
the folded patch files will not be removed afterwards.
The header for each folded patch will be concatenated with the current patch header, separated by a line of * * *.
Returns 0 on success.
Options:
-e, --edit
edit patch header
-k, --keep
keep folded patch files
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qgoto
hg qgoto [OPTION]... PATCH
Returns 0 on success.
Options:
-f, --force
overwrite any local changes
--no-backup
do not save backup copies of files
qguard
hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]
Guards control whether a patch can be pushed. A patch with no guards is always pushed. A patch with a positive guard ("+foo") is pushed
only if the hg qselect command has activated it. A patch with a negative guard ("-foo") is never pushed if the hg qselect command has acti-
vated it.
With no arguments, print the currently active guards. With arguments, set guards for the named patch.
Note Specifying negative guards now requires '--'.
To set guards on another patch:
hg qguard other.patch -- +2.6.17 -stable
Returns 0 on success.
Options:
-l, --list
list all patches and guards
-n, --none
drop all guards
qheader
hg qheader [PATCH]
Returns 0 on success.
qimport
hg qimport [-e] [-n NAME] [-f] [-g] [-P] [-r REV]... FILE...
The patch is inserted into the series after the last applied patch. If no patches have been applied, qimport prepends the patch to the
series.
The patch will have the same name as its source file unless you give it a new one with -n/--name.
You can register an existing patch inside the patch directory with the -e/--existing flag.
With -f/--force, an existing patch of the same name will be overwritten.
An existing changeset may be placed under mq control with -r/--rev (e.g. qimport --rev tip -n patch will place tip under mq control). With
-g/--git, patches imported with --rev will use the git diff format. See the diffs help topic for information on why this is important for
preserving rename/copy information and permission changes. Use hg qfinish to remove changesets from mq control.
To import a patch from standard input, pass - as the patch file. When importing from standard input, a patch name must be specified using
the --name flag.
To import an existing patch while renaming it:
hg qimport -e existing-patch -n new-name
Returns 0 if import succeeded.
Options:
-e, --existing
import file in patch directory
-n, --name
name of patch file
-f, --force
overwrite existing files
-r, --rev
place existing revisions under mq control
-g, --git
use git extended diff format
-P, --push
qpush after importing
qinit
hg qinit [-c]
The queue repository is unversioned by default. If -c/--create-repo is specified, qinit will create a separate nested repository for
patches (qinit -c may also be run later to convert an unversioned patch repository into a versioned one). You can use qcommit to commit
changes to this queue repository.
This command is deprecated. Without -c, it's implied by other relevant commands. With -c, use hg init --mq instead.
Options:
-c, --create-repo
create queue repository
qnew
hg qnew [-e] [-m TEXT] [-l FILE] PATCH [FILE]...
qnew creates a new patch on top of the currently-applied patch (if any). The patch will be initialized with any outstanding changes in the
working directory. You may also use -I/--include, -X/--exclude, and/or a list of files after the patch name to add only changes to matching
files to the new patch, leaving the rest as uncommitted modifications.
-u/--user and -d/--date can be used to set the (given) user and date, respectively. -U/--currentuser and -D/--currentdate set user to cur-
rent user and date to current date.
-e/--edit, -m/--message or -l/--logfile set the patch header as well as the commit message. If none is specified, the header is empty and
the commit message is '[mq]: PATCH'.
Use the -g/--git option to keep the patch in the git extended diff format. Read the diffs help topic for more information on why this is
important for preserving permission changes and copy/rename information.
Returns 0 on successful creation of a new patch.
Options:
-e, --edit
edit commit message
-f, --force
import uncommitted changes (DEPRECATED)
-g, --git
use git extended diff format
-U, --currentuser
add "From: <current user>" to patch
-u, --user
add "From: <USER>" to patch
-D, --currentdate
add "Date: <current date>" to patch
-d, --date
add "Date: <DATE>" to patch
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qnext
hg qnext [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpop
hg qpop [-a] [-f] [PATCH | INDEX]
By default, pops off the top of the patch stack. If given a patch name, keeps popping off patches until the named patch is at the top of
the stack.
Return 0 on success.
Options:
-a, --all
pop all patches
-n, --name
queue name to pop (DEPRECATED)
-f, --force
forget any local changes to patched files
--no-backup
do not save backup copies of files

hg qprev [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qpush
hg qpush [-f] [-l] [-a] [--move] [PATCH | INDEX]
When -f/--force is applied, all local changes in patched files will be lost.
Return 0 on success.
Options:
-f, --force
apply on top of local changes
-e, --exact
apply the target patch to its recorded parent
-l, --list
list patch name in commit text
-a, --all
apply all patches
-m, --merge
merge from another queue (DEPRECATED)
-n, --name
merge queue name (DEPRECATED)
--move reorder patch series and apply only the patch
--no-backup
do not save backup copies of files
qqueue
hg qqueue [OPTION] [QUEUE]
Supports switching between different patch queues, as well as creating new patch queues and deleting existing ones.
Omitting a queue name or specifying -l/--list will show you the registered queues - by default the "normal" patches queue is registered.
The currently active queue will be marked with "(active)". Specifying --active will print only the name of the active queue.
To create a new queue, use -c/--create. The queue is automatically made active, except in the case where there are applied patches from the
currently active queue in the repository. Then the queue will only be created and switching will fail.
To delete an existing queue, use --delete. You cannot delete the currently active queue.
Returns 0 on success.
Options:
-l, --list
list all available queues
--active
print name of active queue
-c, --create
create new queue
--rename
rename active queue
--delete
delete reference to queue
--purge
delete queue, and remove patch dir
qrefresh
hg qrefresh [-I] [-X] [-e] [-m TEXT] [-l FILE] [-s] [FILE]...
If any file patterns are provided, the refreshed patch will contain only the modifications that match those patterns; the remaining modifi-
cations will remain in the working directory.
If -s/--short is specified, files currently included in the patch will be refreshed just like matched files and remain in the patch.
If -e/--edit is specified, Mercurial will start your configured editor for you to enter a message. In case qrefresh fails, you will find a
backup of your message in .hg/last-message.txt.
hg add/remove/copy/rename work as usual, though you might want to use git-style patches (-g/--git or [diff] git=1) to track copies and
renames. See the diffs help topic for more information on the git diff format.
Returns 0 on success.
Options:
-e, --edit
edit commit message
-g, --git
use git extended diff format
-s, --short
refresh only files already in the patch and specified files
-U, --currentuser
add/update author field in patch with current user
-u, --user
add/update author field in patch with given user
-D, --currentdate
add/update date field in patch with current date
-d, --date
add/update date field in patch with given date
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qrename
hg qrename PATCH1 [PATCH2]
With one argument, renames the current patch to PATCH1. With two arguments, renames PATCH1 to PATCH2.
Returns 0 on success.
aliases: qmv
qrestore
hg qrestore [-d] [-u] REV
This command is deprecated, use hg rebase instead.
Options:
-d, --delete
delete save entry
-u, --update
update queue working directory
qsave
hg qsave [-m TEXT] [-l FILE] [-c] [-n NAME] [-e] [-f]
This command is deprecated, use hg rebase instead.
Options:
-c, --copy

-n, --name
copy directory name
-e, --empty
clear queue status file
-f, --force
force copy
-m, --message
use text as commit message
-l, --logfile
read commit message from file
qselect
hg qselect [OPTION]... [GUARD]...
Use the hg qguard command to set or print guards on patch, then use qselect to tell mq which guards to use. A patch will be pushed if it
has no guards or any positive guards match the currently selected guard, but will not be pushed if any negative guards match the current
guard. For example:
qguard foo.patch -- -stable (negative guard)
qguard bar.patch +stable (positive guard)
qselect stable
This activates the "stable" guard. mq will skip foo.patch (because it has a negative match) but push bar.patch (because it has a positive
match).
With no arguments, prints the currently active guards. With one argument, sets the active guard.
Use -n/--none to deactivate guards (no other arguments needed). When no guards are active, patches with positive guards are skipped and
patches with negative guards are pushed.
qselect can change the guards on applied patches. It does not pop guarded patches by default. Use --pop to pop back to the last applied
patch that is not guarded. Use --reapply (which implies --pop) to push back to the current patch afterwards, but skip guarded patches.
Use -s/--series to print a list of all guards in the series file (no other arguments needed). Use -v for more information.
Returns 0 on success.
Options:
-n, --none
disable all guards
-s, --series
list all guards in series file
--pop pop to before first guarded applied patch
--reapply
pop, then reapply patches
qseries
hg qseries [-ms]
Returns 0 on success.
Options:
-m, --missing
print patches not in series
-s, --summary
print first line of patch header
qtop
hg qtop [-s]
Returns 0 on success.
Options:
-s, --summary
print first line of patch header
qunapplied
hg qunapplied [-1] [-s] [PATCH]
Returns 0 on success.
Options:
-1, --first
show only the first patch
-s, --summary
print first line of patch header
strip
hg strip [-k] [-f] [-n] REV...
The strip command removes the specified changesets and all their descendants. If the working directory has uncommitted changes, the opera-
tion is aborted unless the --force flag is supplied, in which case changes will be discarded.
If a parent of the working directory is stripped, then the working directory will automatically be updated to the most recent available
ancestor of the stripped parent after the operation completes.
Any stripped changesets are stored in .hg/strip-backup as a bundle (see hg help bundle and hg help unbundle). They can be restored by run-
ning hg unbundle .hg/strip-backup/BUNDLE, where BUNDLE is the bundle file created by the strip. Note that the local revision numbers will
in general be different after the restore.
Use the --no-backup option to discard the backup bundle once the operation completes.
Return 0 on success.
Options:
-r, --rev
strip specified revision (optional, can specify revisions without this option)
-f, --force
force removal of changesets, discard uncommitted changes (no backup)
-b, --backup
bundle only changesets with local revision number greater than REV which are not descendants of REV (DEPRECATED)
--no-backup
no backups
--nobackup
no backups (DEPRECATED)
-n ignored (DEPRECATED)
-k, --keep
do not modify working copy during strip
notify
hooks for sending email push notifications
This extension let you run hooks sending email notifications when changesets are being pushed, from the sending or receiving side.
First, enable the extension as explained in hg help extensions, and register the hook you want to run. incoming and changegroup hooks are
run by the changesets receiver while the outgoing one is for the sender:
[hooks]
# one email for each incoming changeset
incoming.notify = python:hgext.notify.hook
# one email for all incoming changesets
changegroup.notify = python:hgext.notify.hook
# one email for all outgoing changesets
outgoing.notify = python:hgext.notify.hook
Now the hooks are running, subscribers must be assigned to repositories. Use the [usersubs] section to map repositories to a given email or
the [reposubs] section to map emails to a single repository:
[usersubs]
# key is subscriber email, value is a comma-separated list of glob
# patterns
user@host = pattern
[reposubs]
# key is glob pattern, value is a comma-separated list of subscriber
# emails
pattern = user@host
Glob patterns are matched against absolute path to repository root. The subscriptions can be defined in their own file and referenced with:
[notify]
config = /path/to/subscriptionsfile
Alternatively, they can be added to Mercurial configuration files by setting the previous entry to an empty value.
At this point, notifications should be generated but will not be sent until you set the notify.test entry to False.
Notifications content can be tweaked with the following configuration entries:
notify.test
If True, print messages to stdout instead of sending them. Default: True.
notify.sources
Space separated list of change sources. Notifications are sent only if it includes the incoming or outgoing changes source. Incoming
sources can be serve for changes coming from http or ssh, pull for pulled changes, unbundle for changes added by hg unbundle or push
for changes being pushed locally. Outgoing sources are the same except for unbundle which is replaced by bundle. Default: serve.
notify.strip
Number of leading slashes to strip from url paths. By default, notifications references repositories with their absolute path.
notify.strip let you turn them into relative paths. For example, notify.strip=3 will change /long/path/repository into repository.
Default: 0.
notify.domain
If subscribers emails or the from email have no domain set, complete them with this value.
notify.style
Style file to use when formatting emails.
notify.template
Template to use when formatting emails.
notify.incoming
Template to use when run as incoming hook, override notify.template.
notify.outgoing
Template to use when run as outgoing hook, override notify.template.
notify.changegroup
Template to use when running as changegroup hook, override notify.template.
notify.maxdiff
Maximum number of diff lines to include in notification email. Set to 0 to disable the diff, -1 to include all of it. Default: 300.
notify.maxsubject
Maximum number of characters in emails subject line. Default: 67.
notify.diffstat
Set to True to include a diffstat before diff content. Default: True.
notify.merge
If True, send notifications for merge changesets. Default: True.
notify.mbox
If set, append mails to this mbox file instead of sending. Default: None.
notify.fromauthor
If set, use the first committer of the changegroup for the "From" field of the notification mail. If not set, take the user from the
pushing repo. Default: False.
If set, the following entries will also be used to customize the notifications:
email.from
Email From address to use if none can be found in generated email content.
web.baseurl
Root repository browsing URL to combine with repository paths when making references. See also notify.strip.
pager
browse command output with an external pager
To set the pager that should be used, set the application variable:
[pager]
pager = less -FRSX
If no pager is set, the pager extensions uses the environment variable $PAGER. If neither pager.pager, nor $PAGER is set, no pager is used.
You can disable the pager for certain commands by adding them to the pager.ignore list:
[pager]
ignore = version, help, update
You can also enable the pager only for certain commands using pager.attend. Below is the default list of commands to be paged:
[pager]
attend = annotate, cat, diff, export, glog, log, qdiff
Setting pager.attend to an empty value will cause all commands to be paged.
If pager.attend is present, pager.ignore will be ignored.
To ignore global commands like hg version or hg help, you have to specify them in your user configuration file.
The --pager=... option can also be used to control when the pager is used. Use a boolean value like yes, no, on, off, or use auto for nor-
mal behavior.
patchbomb
command to send changesets as (a series of) patch emails
The series is started off with a "[PATCH 0 of N]" introduction, which describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset description as the subject text. The
message contains two or three body parts:
o The changeset description.
o [Optional] The result of running diffstat on the patch.
o The patch itself, as generated by hg export.
Each message refers to the first in the series using the In-Reply-To and References headers, so they will show up as a sequence in threaded
mail and news readers, and in mail archives.
To configure other defaults, add a section like this to your configuration file:
[email]
from = My Name <my@email>
to = recipient1, recipient2, ...
cc = cc1, cc2, ...
bcc = bcc1, bcc2, ...
reply-to = address1, address2, ...
Use [patchbomb] as configuration section name if you need to override global [email] address settings.
Then you can use the hg email command to mail a series of changesets as a patchbomb.
You can also either configure the method option in the email section to be a sendmail compatible mailer or fill out the [smtp] section so
that the patchbomb extension can automatically send patchbombs directly from the commandline. See the [email] and [smtp] sections in
hgrc(5) for details.
Commands
email
hg email [OPTION]... [DEST]...
By default, diffs are sent in the format generated by hg export, one per message. The series starts with a "[PATCH 0 of N]" introduction,
which describes the series as a whole.
Each patch email has a Subject line of "[PATCH M of N] ...", using the first line of the changeset description as the subject text. The
message contains two or three parts. First, the changeset description.
With the -d/--diffstat option, if the diffstat program is installed, the result of running diffstat on the patch is inserted.
Finally, the patch itself, as generated by hg export.
With the -d/--diffstat or -c/--confirm options, you will be presented with a final summary of all messages and asked for confirmation
before the messages are sent.
By default the patch is included as text in the email body for easy reviewing. Using the -a/--attach option will instead create an attach-
ment for the patch. With -i/--inline an inline attachment will be created. You can include a patch both as text in the email body and as a
regular or an inline attachment by combining the -a/--attach or -i/--inline with the --body option.
With -o/--outgoing, emails will be generated for patches not found in the destination repository (or only those which are ancestors of the
specified revisions if any are provided)
With -b/--bundle, changesets are selected as for --outgoing, but a single email containing a binary Mercurial bundle as an attachment will
be sent.
With -m/--mbox, instead of previewing each patchbomb message in a pager or sending the messages directly, it will create a UNIX mailbox
file with the patch emails. This mailbox file can be previewed with any mail user agent which supports UNIX mbox files.
With -n/--test, all steps will run, but mail will not be sent. You will be prompted for an email recipient address, a subject and an
introductory message describing the patches of your patchbomb. Then when all is done, patchbomb messages are displayed. If the PAGER envi-
ronment variable is set, your pager will be fired up once for each patchbomb message, so you can verify everything is alright.
In case email sending fails, you will find a backup of your series introductory message in .hg/last-email.txt.
Examples:
hg email -r 3000 # send patch 3000 only
hg email -r 3000 -r 3001 # send patches 3000 and 3001
hg email -r 3000:3005 # send patches 3000 through 3005
hg email 3000 # send patch 3000 (deprecated)
hg email -o # send all patches not in default
hg email -o DEST # send all patches not in DEST
hg email -o -r 3000 # send all ancestors of 3000 not in default
hg email -o -r 3000 DEST # send all ancestors of 3000 not in DEST
hg email -b # send bundle of all patches not in default
hg email -b DEST # send bundle of all patches not in DEST
hg email -b -r 3000 # bundle of all ancestors of 3000 not in default
hg email -b -r 3000 DEST # bundle of all ancestors of 3000 not in DEST
hg email -o -m mbox && # generate an mbox file...
mutt -R -f mbox # ... and view it with mutt
hg email -o -m mbox && # generate an mbox file ...
formail -s sendmail # ... and use formail to send from the mbox
-bm -t < mbox # ... using sendmail
Before using this command, you will need to enable email in your hgrc. See the [email] section in hgrc(5) for details.

progress
show progress bars for some actions
This extension uses the progress information logged by hg commands to draw progress bars that are as informative as possible. Some progress
bars only offer indeterminate information, while others have a definite end point.
The following settings are available:
[progress]
delay = 3 # number of seconds (float) before showing the progress bar
changedelay = 1 # changedelay: minimum delay before showing a new topic.
# If set to less than 3 * refresh, that value will
# be used instead.
refresh = 0.1 # time in seconds between refreshes of the progress bar
format = topic bar number estimate # format of the progress bar
width = <none> # if set, the maximum width of the progress information
# (that is, min(width, term width) will be used)
clear-complete = True # clear the progress bar after it's done
disable = False # if true, don't show a progress bar
assume-tty = False # if true, ALWAYS show a progress bar, unless
# disable is given
Valid entries for the format field are topic, bar, number, unit, estimate, speed, and item. item defaults to the last 20 characters of the
item, but this can be changed by adding either -<num> which would take the last num characters, or +<num> for the first num characters.
purge
command to delete untracked files from the working directory
Commands
purge
hg purge [OPTION]... [DIR]...
Delete files not known to Mercurial. This is useful to test local and uncommitted changes in an otherwise-clean source tree.
This means that purge will delete:
o Unknown files: files marked with "?" by hg status
o Empty directories: in fact Mercurial ignores directories unless they contain files under source control management
But it will leave untouched:
o Modified and unmodified tracked files
o Ignored files (unless --all is specified)
o New files added to the repository (with hg add)
If directories are given on the command line, only files in these directories are considered.
Be careful with purge, as you could irreversibly delete some files you forgot to add to the repository. If you only want to print the list
of files that this program would delete, use the --print option.
Options:
-a, --abort-on-err
abort if an error occurs
--all purge ignored files too
-p, --print
print filenames instead of deleting them
-0, --print0
end filenames with NUL, for use with xargs (implies -p/--print)
-I, --include
include names matching the given patterns
-X, --exclude
exclude names matching the given patterns
aliases: clean
rebase
command to move sets of revisions to a different ancestor
This extension lets you rebase changesets in an existing Mercurial repository.
For more information: http://mercurial.selenic.com/wiki/RebaseExtension
Commands
rebase
hg rebase [-s REV | -b REV] [-d REV] [options]
hg rebase {-a|-c}
Rebase uses repeated merging to graft changesets from one part of history (the source) onto another (the destination). This can be useful
for linearizing local changes relative to a master development tree.
You should not rebase changesets that have already been shared with others. Doing so will force everybody else to perform the same rebase
or they will end up with duplicated changesets after pulling in your rebased changesets.
If you don't specify a destination changeset (-d/--dest), rebase uses the tipmost head of the current named branch as the destination. (The
destination changeset is not modified by rebasing, but new changesets are added as its descendants.)
You can specify which changesets to rebase in two ways: as a "source" changeset or as a "base" changeset. Both are shorthand for a topolog-
ically related set of changesets (the "source branch"). If you specify source (-s/--source), rebase will rebase that changeset and all of
its descendants onto dest. If you specify base (-b/--base), rebase will select ancestors of base back to but not including the common
ancestor with dest. Thus, -b is less precise but more convenient than -s: you can specify any changeset in the source branch, and rebase
will select the whole branch. If you specify neither -s nor -b, rebase uses the parent of the working directory as the base.
By default, rebase recreates the changesets in the source branch as descendants of dest and then destroys the originals. Use --keep to pre-
serve the original source changesets. Some changesets in the source branch (e.g. merges from the destination branch) may be dropped if they
no longer contribute any change.
One result of the rules for selecting the destination changeset and source branch is that, unlike merge, rebase will do nothing if you are
at the latest (tipmost) head of a named branch with two heads. You need to explicitly specify source and/or destination (or update to the
other head, if it's the head of the intended source branch).
If a rebase is interrupted to manually resolve a merge, it can be continued with --continue/-c or aborted with --abort/-a.
Returns 0 on success, 1 if nothing to rebase.
Options:
-s, --source
rebase from the specified changeset
-b, --base
rebase from the base of the specified changeset (up to greatest common ancestor of base and dest)
-r, --rev
rebase these revisions
-d, --dest
rebase onto the specified changeset
--collapse
collapse the rebased changesets
-m, --message
use text as collapse commit message
-e, --edit
invoke editor on commit messages
-l, --logfile
read collapse commit message from file
--keep keep original changesets
--keepbranches
keep original branch names
-D, --detach
force detaching of source from its original branch
-t, --tool
specify merge tool
-c, --continue
continue an interrupted rebase
-a, --abort
abort an interrupted rebase
--style
display using template map file
--template
display with template
record
commands to interactively select changes for commit/qrefresh
Commands
qrecord
hg qrecord [OPTION]... PATCH [FILE]...
See hg help qnew & hg help record for more information and usage.
record
hg record [OPTION]... [FILE]...
If a list of files is omitted, all changes reported by hg status will be candidates for recording.
See hg help dates for a list of formats valid for -d/--date.
You will be prompted for whether to record changes to each modified file, and for files with multiple changes, for each change to use. For
each query, the following responses are possible:
y - record this change
n - skip this change
e - edit this change manually
s - skip remaining changes to this file
f - record remaining changes to this file
d - done, skip remaining changes and files
a - record all changes to all remaining files
q - quit, recording no changes
? - display help
This command is not available when committing a merge.
Options:
-A, --addremove
mark new/missing files as added/removed before committing
--close-branch
mark a branch as closed, hiding it from the branch list
--amend
amend the parent of the working dir

relink
recreates hardlinks between repository clones
Commands
relink
hg relink [ORIGIN]
When repositories are cloned locally, their data files will be hardlinked so that they only use the space of a single repository.
Unfortunately, subsequent pulls into either repository will break hardlinks for any files touched by the new changesets, even if both
repositories end up pulling the same changes.
Similarly, passing --rev to "hg clone" will fail to use any hardlinks, falling back to a complete copy of the source repository.
This command lets you recreate those hardlinks and reclaim that wasted space.
This repository will be relinked to share space with ORIGIN, which must be on the same local disk. If ORIGIN is omitted, looks for
"default-relink", then "default", in [paths].
Do not attempt any read operations on this repository while the command is running. (Both repositories will be locked against writes.)
schemes
extend schemes with shortcuts to repository swarms
This extension allows you to specify shortcuts for parent URLs with a lot of repositories to act like a scheme, for example:
[schemes]
py = http://code.python.org/hg/
After that you can use it like:
hg clone py://trunk/
Additionally there is support for some more complex schemas, for example used by Google Code:
[schemes]
gcode = http://{1}.googlecode.com/hg/
The syntax is taken from Mercurial templates, and you have unlimited number of variables, starting with {1} and continuing with {2}, {3}
and so on. This variables will receive parts of URL supplied, split by /. Anything not specified as {part} will be just appended to an URL.
For convenience, the extension adds these schemes by default:
[schemes]
py = http://hg.python.org/
bb = https://bitbucket.org/
bb+ssh = ssh://hg@bitbucket.org/
gcode = https://{1}.googlecode.com/hg/
kiln = https://{1}.kilnhg.com/Repo/
You can override a predefined scheme by defining a new scheme with the same name.
share
share a common history between several working directories
Commands
share
hg share [-U] SOURCE [DEST]
Initialize a new repository and working directory that shares its history with another repository.
Note using rollback or extensions that destroy/modify history (mq, rebase, etc.) can cause considerable confusion with shared clones. In
particular, if two shared clones are both updated to the same changeset, and one of them destroys that changeset with rollback, the
other clone will suddenly stop working: all operations will fail with "abort: working directory has unknown parent". The only known
workaround is to use debugsetparents on the broken clone to reset it to a changeset that still exists (e.g. tip).
Options:
-U, --noupdate
do not create a working copy
unshare
hg unshare
Copy the store data to the repo and remove the sharedpath data.
transplant
command to transplant changesets from another branch
This extension allows you to transplant patches from another branch.
Transplanted patches are recorded in .hg/transplant/transplants, as a map from a changeset hash to its hash in the source repository.
Commands
transplant
hg transplant [-s REPO] [-b BRANCH [-a]] [-p REV] [-m REV] [REV]...
Selected changesets will be applied on top of the current working directory with the log of the original changeset. The changesets are
copied and will thus appear twice in the history. Use the rebase extension instead if you want to move a whole branch of unpublished
changesets.
If --log is specified, log messages will have a comment appended of the form:
(transplanted from CHANGESETHASH)
You can rewrite the changelog message with the --filter option. Its argument will be invoked with the current changelog message as $1 and
the patch as $2.
If --source/-s is specified, selects changesets from the named repository. If --branch/-b is specified, selects changesets from the branch
holding the named revision, up to that revision. If --all/-a is specified, all changesets on the branch will be transplanted, otherwise you
will be prompted to select the changesets you want.
hg transplant --branch REVISION --all will transplant the selected branch (up to the named revision) onto your current working directory.
You can optionally mark selected transplanted changesets as merge changesets. You will not be prompted to transplant any ancestors of a
merged transplant, and you can merge descendants of them normally instead of transplanting them.
Merge changesets may be transplanted directly by specifying the proper parent changeset by calling hg transplant --parent.
If no merges or revisions are provided, hg transplant will start an interactive changeset browser.
If a changeset application fails, you can fix the merge by hand and then resume where you left off by calling hg transplant --continue/-c.
Options:
-s, --source
pull patches from REPO
-b, --branch
pull patches from branch BRANCH
-a, --all
pull all changesets up to BRANCH
-p, --prune
skip over REV
-m, --merge
merge at REV
--parent
parent to choose when transplanting merge
-e, --edit
invoke editor on commit messages
--log append transplant info to log message
-c, --continue
continue last transplant session after repair
--filter
filter changesets through command
win32mbcs
allow the use of MBCS paths with problematic encodings
Some MBCS encodings are not good for some path operations (i.e. splitting path, case conversion, etc.) with its encoded bytes. We call
such a encoding (i.e. shift_jis and big5) as "problematic encoding". This extension can be used to fix the issue with those encodings by
wrapping some functions to convert to Unicode string before path operation.
This extension is useful for:
o Japanese Windows users using shift_jis encoding.
o Chinese Windows users using big5 encoding.
o All users who use a repository with one of problematic encodings on case-insensitive file system.
This extension is not needed for:
o Any user who use only ASCII chars in path.
o Any user who do not use any of problematic encodings.
Note that there are some limitations on using this extension:
o You should use single encoding in one repository.
o If the repository path ends with 0x5c, .hg/hgrc cannot be read.
o win32mbcs is not compatible with fixutf8 extension.
By default, win32mbcs uses encoding.encoding decided by Mercurial. You can specify the encoding by config option:
[win32mbcs]
encoding = sjis
It is useful for the users who want to commit with UTF-8 log message.
win32text
perform automatic newline conversion
Deprecation: The win32text extension requires each user to configure the extension again and again for each clone since the configura-
tion is not copied when cloning.
We have therefore made the eol as an alternative. The eol uses a version controlled file for its configuration and each clone will
therefore use the right settings from the start.
To perform automatic newline conversion, use:
[extensions]
win32text =
[encode]
** = cleverencode:
# or ** = macencode:
[decode]
** = cleverdecode:
# or ** = macdecode:
If not doing conversion, to make sure you do not commit CRLF/CR by accident:
[hooks]
pretxncommit.crlf = python:hgext.win32text.forbidcrlf
# or pretxncommit.cr = python:hgext.win32text.forbidcr
To do the same check on a server to prevent CRLF/CR from being pushed or pulled:
[hooks]
pretxnchangegroup.crlf = python:hgext.win32text.forbidcrlf
# or pretxnchangegroup.cr = python:hgext.win32text.forbidcr
zeroconf
discover and advertise repositories on the local network
The zeroconf extension will advertise hg serve instances over DNS-SD so that they can be discovered using the hg paths command without
knowing the server's address.
To allow other people to discover your repository using run hg serve in your repository:
$ cd test
$ hg serve
You can discover Zeroconf-enabled repositories by running hg paths:
$ hg paths
zc-test = http://example.com:8000/test
FILES
/etc/mercurial/hgrc, $HOME/.hgrc, .hg/hgrc
This file contains defaults and configuration. Values in .hg/hgrc override those in $HOME/.hgrc, and these override settings made in
the global /etc/mercurial/hgrc configuration. See hgrc(5) for details of the contents and format of these files.
.hgignore
This file contains regular expressions (one per line) that describe file names that should be ignored by hg. For details, see
hgignore(5).
.hgsub
This file defines the locations of all subrepositories, and tells where the subrepository checkouts came from. For details, see hg
help subrepos.
.hgsubstate
This file is where Mercurial stores all nested repository states. NB: This file should not be edited manually.
.hgtags
This file contains changeset hash values and text tag names (one of each separated by spaces) that correspond to tagged versions of
the repository contents. The file content is encoded using UTF-8.
.hg/last-message.txt
This file is used by hg commit to store a backup of the commit message in case the commit fails.
.hg/localtags
This file can be used to define local tags which are not shared among repositories. The file format is the same as for .hgtags, but
it is encoded using the local system encoding.
Some commands (e.g. revert) produce backup files ending in .orig, if the .orig file already exists and is not tracked by Mercurial, it will
be overwritten.
BUGS
Probably lots, please post them to the mailing list (see Resources below) when you find them.
