Module::Manifest - Parse and examine a Perl distribution MANIFEST file
Open and parse a MANIFEST and MANIFEST.SKIP:
my $manifest = Module::Manifest->new( 'MANIFEST', 'MANIFEST.SKIP' );
Check if a given file matches any known skip masks:
print "yes\n" if $manifest->skipped('.svn');
Module::Manifest is a simple utility module created originally for use in the Module::Inspector manpage.
It can load a MANIFEST file that comes in a Perl distribution tarball, examine the contents, and perform some simple tasks. It can also load the MANIFEST.SKIP file and check that.
Granted, the functionality needed to do this is quite simple, but the Perl distribution MANIFEST specification contains a couple of little idiosyncracies, such as line comments and space-seperated inline comments.
The use of this module means that any little nigglies are dealt with behind the scenes, and you can concentrate the main task at hand.
This module is quite similar to the ExtUtils::Manifest manpage, or is at least similar in scope. However, there is a general difference in approach.
the ExtUtils::Manifest manpage is imperative, requires the existance of the actual MANIFEST file on disk, and requires that your current directory remains the same.
the Module::Manifest manpage treats the MANIFEST file as an object, can load a the file from anywhere on disk, and can run some of the same functionality without having to change your current directory context.
That said, note that the Module::Manifest manpage is aimed at reading and checking existing MANFIFEST files, rather than creating new ones.
This module should be compatible with Perl 5.005 and above. However, it has only been rigorously tested under Perl 5.10.0 on Linux.
If you encounter any problems on a different version or architecture, please contact the maintainer.
Module::Manifest->new( $manifest, $skip )
Creates a Module::Manifest object, which either parses the files
referenced by the $manifest (for MANIFEST) and $skip
(for MANIFEST.SKIP). If no parameters are specified, it creates an empty
object.
Example code:
my $manifest = Module::Manifest->new; my $manifest = Module::Manifest->new( $manifest ); my $manifest = Module::Manifest->new( $manifest, $skip );
This method will return an appropriate Module::Manifest object or throws an exception on error.
$manifest->open( $type => $filename )
Open and parse the file given by $filename, which may be a relative path.
The available $type options are either: 'skip' or 'manifest'
Example code:
$manifest->open( skip => 'MANIFEST.SKIP' ); $manifest->open( manifest => 'MANIFEST' );
This method doesn't return anything, but may throw an exception on error.
$manifest->parse( $type => \@files )
Parse \@files, which is an array reference containing a list of files or
regular expression masks. The available $type options are either: 'skip'
or 'manifest'
Example code:
$manifest->parse( skip => [
'\B\.svn\b',
'^Build$',
'\bMakefile$',
]);
This method doesn't return anything, but may throw an exception on error.
$manifest->skipped( $filename )
Check if $filename matches any masks that should be skipped, given the
regular expressions provided to either the parse or open methods.
Absolute path names must first be relativized and converted to a Unix-like
path string by using the normalize method.
Example code:
if ($manifest->skipped('Makefile.PL')) {
# do stuff
}
This method returns a boolean true or false value indicating whether the
file path is skipped according the skipfile.
Module::Manifest->normalize( $path, $rel ) $manifest->normalize( $path, $rel )
This method takes a given platform-specific path string and converts it to a Unix-style string compatible with the MANIFEST and MANIFEST.SKIP specifications.
Note that this method normalizes paths depending on the platform detected
by $^O -- that is, Win32 style paths can only be normalized if the
module is currently running under Win32.
By default, this method will relativize file paths to the current working
directory (using the File::Spec manpage's abs2rel method without a $root). To
disable this behaviour, set $rel to a false value.
Example code:
# Useful for normalizing Win32-style paths
my $normal = Module::Manifest->normalize('t\\test\\file');
# Returns: t/test/file (ie, in Unix style for MANIFEST)
This returns a normalized version of the given path.
$manifest->file
The file accessor returns the absolute path of the MANIFEST file that
was loaded.
$manifest->skipfile
The skipfile accessor returns the absolute path of the MANIFEST.SKIP file
that was loaded.
$manifest->dir
The dir accessor returns the path to the directory that contains the
MANIFEST or skip file, and thus SHOULD be the root of the distribution.
$manifest->files
The files method returns the (relative, unix-style) list of files within
the manifest. In scalar context, returns the number of files in the manifest.
Example code:
my @files = $manifest->files;
The directory returned by the dir method is overwritten whenever open
is called. This means that, if MANIFEST and MANIFEST.SKIP are not in the
same directory, the module may get a bit confused.
This module is stored in an Open Repository at the following address:
http://svn.ali.as/cpan/trunk/Module-Manifest
Write access to the repository is made available automatically to any published CPAN author, and to most other volunteers on request.
If you are able to submit your bug report in the form of new (failing) unit tests, or can apply your fix directly instead of submitting a patch, you are strongly encouraged to do so. The author currently maintains over 100 modules and it may take some time to deal with non-critical bug reports or patches.
This will guarantee that your issue will be addressed in the next release of the module.
If you cannot provide a direct test or fix, or don't have time to do so, then regular bug reports are still accepted and appreciated via the CPAN bug tracker.
http://rt.cpan.org/NoAuth/ReportBug.html
For other issues, for commercial enhancement and support, or to have your write access enabled for the repository, contact the author at the email address above.
