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

    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, ...});

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 CWMANIFEST in the current directory really do exist. If CWMANIFEST 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 CWMANIFEST 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 CWMANIFEST file. An optional file CWMANIFEST.SKIP will be consulted. Any file matching a regular expression in such a file will not be reported as missing in the CWMANIFEST 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 CWMANIFEST.SKIP file.

maniread

    my $manifest = maniread();
    my $manifest = maniread($manifest_file);

reads a named CWMANIFEST file (defaults to CWMANIFEST 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 CW# in the CWMANIFEST file are discarded.

manicopy

    manicopy($src, $dest_dir);
    manicopy($src, $dest_dir, $how);

copies the files that are the keys in the HASH %$src to the CW$dest_dir. The HASH reference CW$read is typically returned by the maniread() function. This function is useful for producing a directory tree identical to the intended distribution tree. The third parameter CW$how can be used to specify a different methods of copying. Valid values are CWcp, which actually copies the files, CWln which creates hard links, and CWbest which mostly links the files but copies any symbolic link to make a tree without any symbolic link. Best 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

Anything between white space and an end of line within a CWMANIFEST file is considered to be a comment. Filenames and comments are separated by one or more TAB characters in the output.

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 CW# are skipped. Use CW\# if you need a regular expression to start with a sharp character. A typical 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.

CW&mkmanifest, CW&manicheck, CW&filecheck, CW&fullcheck, CW&maniread, and CW&manicopy are exportable.

CW$ExtUtils::Manifest::MANIFEST defaults to CWMANIFEST. Changing it results in both a different CWMANIFEST and a different CWMANIFEST.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).

CW$ExtUtils::Manifest::Quiet defaults to 0. If set to a true value, all functions act silently.

CW$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.

All diagnostic output is sent to CWSTDERR. is reported if a file is found which is not in CWMANIFEST. is reported if a file is skipped due to an entry in CWMANIFEST.SKIP. is reported if a file mentioned in a CWMANIFEST file does not exist. is reported if CWMANIFEST could not be opened. is reported by mkmanifest() if CW$Verbose is set and a file is added to MANIFEST. CW$Verbose is set to 1 by default.

PERL_MM_MANIFEST_DEBUG

Turns on debugging

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