NAME

       hgignore - 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.

SYNTAX

       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/
