# 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

          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 the HASH %$src to the $dest_dir. 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 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

## MANIFEST

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.

## 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 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.

## 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
