# ExtUtils::Manifest

Perl 5 version 10.1 documentation

# 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, ...});

# DESCRIPTION

## 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 the result of the Unix command

    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.

• 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.

• maniskip
    my $skipchk = maniskip(); my$skipchk = maniskip($manifest_skip_file); if ($skipchk->($file)) { .. } reads a named MANIFEST.SKIP file (defaults to MANIFEST.SKIP in the current directory) and returns a CODE reference that tests whether a given filename should be skipped. • manicopy  manicopy(\%src,$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.

$how can be used to specify a different methods of "copying". Valid values are cp , which actually copies the files, ln which creates hard links, and best which mostly links the files but copies any symbolic link to make a tree without any symbolic link. cp is the default. • maniadd  maniadd({$file => $comment, ...}); Adds an entry to an existing MANIFEST unless its already there.$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. Beginning with ExtUtils::Manifest 1.52, a filename may contain whitespace characters if it is enclosed in single quotes; single quotes or backslashes in that filename must be backslash-escaped.

    # this a comment    some/file    some/other/file            comment about some/file    'some/third file'          comment

## 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. In one's own MANIFEST.SKIP file, certain directives can be used to include the contents of other MANIFEST.SKIP files. At present two such directives are recognized. • #!include_default This inserts the contents of the default MANIFEST.SKIP file • #!include /Path/to/another/manifest.skip This inserts the contents of the specified external file The included contents will be inserted into the MANIFEST.SKIP file in between #!start included /path/to/manifest.skip and #!end included /path/to/manifest.skip markers. The original MANIFEST.SKIP is saved as MANIFEST.SKIP.bak. ## 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

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