NAME

       Module::Inspector - An integrated API for inspecting Perl distributions

DESCRIPTION

       An entire ecosystem of CPAN modules exist around the files and formats relating to the
       CPAN itself. Parsers and object models for various different types of files have been
       created over the years by various people for various projects.

       These modules have a variety of different styles, and work in various different ways.

       So when it comes to analysing the structure of a Perl module (either inside a repository,
       in a tarball, or in unpacked form) it is certainly quite possible to do.

       It's just that often it takes a high level of experience with the various modules in
       question, and the knowledge of how to combine the dozen of so modules in one cohesive
       program.

       Personally, I have always found this laborious.

       What I would prefer is a single API that is easy to use, implements the magic invisibly
       behind the scenes, and co-ordinates the use of the various modules for me as needed.

       Module::Inspector provides such an API, and provides a companion to the Class::Inspector
       API for accessing information on class after installation.

       It provides a wrapper around the various modules used to read and examine the different
       parts of a Perl module distribution tarball, and can inspect a module unrolled on disk, in
       a repository checkout, or just look directly inside a tarball.

METHODS

   new
         # Inspect a plain dist directory or cvs/svn checkout
         my $dir = Module::Inspector->new(
                 dist_dir => $dirpath,
                 );

         # Inspect a tarball
         my $file = Module::Inspector->new(
                 dist_file => 'Foo-Bar-0.01.tar.gz',
                 );

       The "new" constructor creates a new module inspector. It takes a named param of either
       "dist_file", which should be the file path of the dist tarball, or "dist_dir", which is
       the root of the distribution directory (if it is already unrolled).

       The distribution will be quickly pre-scanned to locate the various significant documents
       in the distribution (although only a few are initially supported).

       Returns a new "Module::Inspector" object, or dies on exception.

   version_control
         my $vcs_type = $self->version_control;

       For reasons that will hopefully be more apparant later, Module::Inspector detects any
       version control system in use within the "dist_dir" for the module.

       Currently, support is limited to detection of CVS and Subversion.

       Returns a the name of the version control system detected in use as a string (currently
       'cvs' or 'svn'). If no version control is able to be detected returns the null string ''.

   documents
       The "documents" method returns a list of the names of all the documents detected by the
       "Module::Inspector".

       In scalar context, returns the number of identifyable documens found in the distribution.

   document_type
         # Returns 'PPI::Document::File'
         my $ppi_class = $inspector->document_type('lib/Foo.pm');

       In Module::Inspector, all documents are represented as objects.

       Thus, for each different type of document, there is going to be a different class that
       implements the document objects for that type.

       The "document_type" method returns the type for a provided document as a class name.

       Please note that at this time these document types are not necesarily stable, and over the
       first several releases I may need to change the class I'm using to represent a particular
       document type.

   document
         my $perl = $inspector->document('lib/Foo.pm');

       The "document" method returns the document object for a named file, loading and caching it
       on the fly if needed.

       The type of object will vary depending on the document.

       For example, a Perl file will be returned as a PPI::Document, a MANIFEST file as a
       Module::Manifest, and so on.

       Returns an object, or dies on error.

   dist_name
         # Returns Config-Tiny
         my $name = $inspector->dist_name;

       The "dist_name" method returns the name of the distribution, as determined from the
       META.yml file.

       Returns the name as a string, or dies on error.

   dist_version
       The "dist_version" method returns the version of the distribution, as determined from the
       META.yml file in the distribution.

       Returns a version object, or dies on error.

   dist_requires
         my $depends = $inspector->dist_requires;

       The "dist_requires" method checks for any run-time dependencies of the distribution and
       returns them as a Module::Math::Depends object.

       See the docs for Module::Math::Depends for more information on its structure and API.

       If the distribution has no run-time dependencies, the object will still be returned, but
       will be empty.

       Returns a single Module::Math::Depends object, or dies on error.

   dist_build_requires
       The "dist_build_requires" method returns the build-time-only dependencies of the
       distribution.

       If there are no build-time dependencies, the object will still be returned, but will be
       empty.

       Returns a Module::Math::Depends object, or dies on exception.

   dist_depends
       The "dist_depends" method returns as for the two methods above ("dist_requires" and
       "dist_build_requires") except that this method returns a merged dependency object,
       representing BOTH the install-time and run-time dependencies for the distribution.

       If there are no build-time or run-time dependencies, the object will be returned, but will
       be empty.

       Returns a Module::Math::Depends object, or dies on error.

TO DO

       - Implement most of the functionality

SUPPORT

       This module is stored in an Open Repository at the following address.

       <http://svn.ali.as/cpan/trunk/Module-Inspector>

       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 as the author currently maintains over 100 modules and it can take some time to deal
       with non-Critcal bug reports or patches.

       This will guarentee 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?Queue=Module-Inspector>

       For other issues, for commercial enhancement or support, or to have your write access
       enabled for the repository, contact the author at the email address above.
