## NAME

ExtUtils::Manifest - utilities to write and check a MANIFEST file

## SYNOPSIS

    use ExtUtils::Manifest qw(...funcs to import...);



    mkmanifest();



    my @missing_files    = manicheck;
my @skipped          = skipcheck;
my @extra_files      = filecheck;
my($missing,$extra) = fullcheck;



    my $found = manifind();   my$manifest = maniread();



    manicopy($read,$target);



    maniadd({$file =>$comment, ...});



## Functions

ExtUtils::Manifest exports no functions by default. The following are exported on request
mkmanifest
    mkmanifest();



Writes all files in and below the current directory to your MANIFEST. It works similar to

    find . > MANIFEST



All files that match any regular expression in a file MANIFEST.SKIP (if it exists) are ignored.

Any existing MANIFEST file will be saved as MANIFEST.bak. Lines from the old MANIFEST file is preserved, including any comments that are found in the existing MANIFEST file in the new one.

manifind
    my $found = manifind();  returns a hash reference. The keys of the hash are the files found below the current directory. manicheck  my @missing_files = manicheck();  checks if all the files within a "MANIFEST" in the current directory really do exist. If "MANIFEST" and the tree below the current directory are in sync it silently returns an empty list. Otherwise it returns a list of files which are listed in the "MANIFEST" but missing from the directory, and by default also outputs these names to STDERR. filecheck  my @extra_files = filecheck();  finds files below the current directory that are not mentioned in the "MANIFEST" file. An optional file "MANIFEST.SKIP" will be consulted. Any file matching a regular expression in such a file will not be reported as missing in the "MANIFEST" file. The list of any extraneous files found is returned, and by default also reported to STDERR. fullcheck  my($missing, $extra) = fullcheck();  does both a manicheck() and a filecheck(), returning then as two array refs. skipcheck  my @skipped = skipcheck();  lists all the files that are skipped due to your "MANIFEST.SKIP" file. maniread  my$manifest = maniread();
my $manifest = maniread($manifest_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
    manicopy(\%src, $dest_dir); manicopy(\%src,$dest_dir, $how);  Copies the files that are the keys in %src to the$dest_dir. %src is typically returned by the maniread() function.

    manicopy( maniread(), $dest_dir );  This function is useful for producing a directory tree identical to the intended distribution tree.$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 without any symbolic link. "cp" is the default.

  maniadd({ $file =>$comment, ...});



$file will be normalized (ie. Unixified). UNIMPLEMENTED ## MANIFEST A list of files in the distribution, one file per line. The MANIFEST always uses Unix filepath conventions even if you're not on Unix. This means foo/bar style not foo\bar. Anything between white space and an end of line within a "MANIFEST" file is considered to be a comment. Any line beginning with # is also a comment.  # this a comment some/file some/other/file comment about some/file  ## MANIFEST.SKIP The file MANIFEST.SKIP may contain regular expressions of files that should be ignored by mkmanifest() and filecheck(). The regular expressions should appear one on each line. Blank lines and lines which start with "#" are skipped. Use "\#" if you need a regular expression to start with a "#". For example:  # Version control files and dirs. \bRCS\b \bCVS\b ,v$
\B\.svn\b



    # 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.

## GLOBALVARIABLES

$ExtUtils::Manifest::MANIFEST defaults to "MANIFEST". Changing it results in both a different "MANIFEST" and a different "MANIFEST.SKIP" file. This is useful if you want to maintain different distributions for different audiences (say a user version and a developer version including RCS).$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.
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

ExtUtils::MakeMaker which has handy targets for most of the functionality.
