NAME
ExtUtils::Manifest - utilities to write and check a MANIFEST file
SYNOPSIS
require ExtUtils::Manifest;
ExtUtils::Manifest::mkmanifest;
ExtUtils::Manifest::manicheck;
ExtUtils::Manifest::filecheck;
ExtUtils::Manifest::fullcheck;
ExtUtils::Manifest::skipcheck;
ExtUtils::Manifest::manifind();
ExtUtils::Manifest::maniread($file);
ExtUtils::Manifest::manicopy($read,$target,$how);
DESCRIPTION
mkmanifest() writes all files in and below the current directory to a file named in the global variable $ExtUtils::Manifest::MANIFEST
(which defaults to "MANIFEST") in the current directory. It works similar to
find . -print
but in doing so checks each line in an existing "MANIFEST" file and includes any comments that are found in the existing "MANIFEST" file in
the new one. Anything between white space and an end of line within a "MANIFEST" file is considered to be a comment. Filenames and comments
are separated by one or more TAB characters in the output. All files that match any regular expression in a file "MANIFEST.SKIP" (if such a
file exists) are ignored.
manicheck() checks if all the files within a "MANIFEST" in the current directory really do exist. If "MANIFEST" and the tree below the cur-
rent directory are in sync it exits silently, returning an empty list. Otherwise it returns a list of files which are listed in the "MANI-
FEST" but missing from the directory, and by default also outputs these names to STDERR.
filecheck() finds files below the current directory that are not mentioned in the "MANIFEST" file. An optional file "MANIFEST.SKIP" will be
consulted. Any file matching a regular expression in such a file will not be reported as missing in the "MANIFEST" file. The list of any
extraneous files found is returned, and by default also reported to STDERR.
fullcheck() does both a manicheck() and a filecheck(), returning references to two arrays, the first for files manicheck() found to be
missing, the seond for unexpeced files found by filecheck().
skipcheck() lists all the files that are skipped due to your "MANIFEST.SKIP" file.
manifind() returns a hash reference. The keys of the hash are the files found below the current directory.
maniread($file) reads a named "MANIFEST" file (defaults to "MANIFEST" in the current directory) and returns a HASH reference with files
being the keys and comments being the values of the HASH. Blank lines and lines which start with "#" in the "MANIFEST" file are discarded.
"manicopy($read,$target,$how)" copies the files that are the keys in the HASH %$read to the named target directory. The HASH reference
$read is typically returned by the maniread() function. This function is useful for producing a directory tree identical to the intended
distribution tree. The third parameter $how can be used to specify a different methods of "copying". Valid values are "cp", which actually
copies the files, "ln" which creates hard links, and "best" which mostly links the files but copies any symbolic link to make a tree with-
out any symbolic link. Best is the default.
MANIFEST.SKIP
The file MANIFEST.SKIP may contain regular expressions of files that should be ignored by mkmanifest() and filecheck(). The regular expres-
sions should appear one on each line. Blank lines and lines which start with "#" are skipped. Use "#" if you need a regular expression to
start with a sharp character. A typical example:
# Version control files and dirs.
RCS
CVS
,v$
# Makemaker generated files and dirs.
^MANIFEST.
^Makefile$
^blib/
^MakeMaker-d
# Temp, old and emacs backup files.
~$
.old$
^#.*#$
^.#
If no MANIFEST.SKIP file is found, a default set of skips will be used, similar to the example above. If you want nothing skipped, simply
make an empty MANIFEST.SKIP file.
EXPORT_OK
&mkmanifest, &manicheck, &filecheck, &fullcheck, &maniread, and &manicopy are exportable.
GLOBAL VARIABLES
$ExtUtils::Manifest::MANIFEST defaults to "MANIFEST". Changing it results in both a different "MANIFEST" and a different "MANIFEST.SKIP"
file. This is useful if you want to maintain different distributions for different audiences (say a user version and a developer version
including RCS).
$ExtUtils::Manifest::Quiet defaults to 0. If set to a true value, all functions act silently.
$ExtUtils::Manifest::Debug defaults to 0. If set to a true value, or if PERL_MM_MANIFEST_DEBUG is true, debugging output will be produced.
DIAGNOSTICS
All diagnostic output is sent to "STDERR".
"Not in MANIFEST:" file
is reported if a file is found which is not in "MANIFEST".
"Skipping" file
is reported if a file is skipped due to an entry in "MANIFEST.SKIP".
"No such file:" file
is reported if a file mentioned in a "MANIFEST" file does not exist.
"MANIFEST:" $!
is reported if "MANIFEST" could not be opened.
"Added to MANIFEST:" file
is reported by mkmanifest() if $Verbose is set and a file is added to MANIFEST. $Verbose is set to 1 by default.
ENVIRONMENT
PERL_MM_MANIFEST_DEBUG
Turns on debugging
