NAME
    File::PackageIndexer - Indexing of packages and subs

SYNOPSIS
      use File::PackageIndexer;
      my $indexer = File::PackageIndexer->new();
      my $pkgs = $indexer->parse( $ppi_document_or_code_string );
  
      use Data::Dumper;
      print Dumper $pkgs;
      # prints something like:
      # {
      #   Some::Package => {
      #     name => 'Some::Package',
      #     subs => {
      #       new => 1,
      #       foo => 1,
      #     },
      #     isa => [ 'SuperClass1', 'SuperClass2' ],
      #   },
      #   ... other pkgs ...
      # }

DESCRIPTION
    Parses a piece of Perl code using PPI and tries to find all subs and
    their packages as well as the inheritance of the packages.

    Currently, the following constructs are recognized:

    "package" statements
    plain subroutine declarations
    "Class::Accessor"-like accessor generation
    "Class::XSAccessor" and "Class::XSAccessor::Array"
    "use base ..." inheritance declaration
    "use parent ..." inheritance declaration
    "our @ISA = ..." and "@ISA = ..." inheritance declaration
    "push @ISA, ..." and "unshift @ISA, ..." inheritance modification

    The inheritance detection (hopefully) correctly recognizes the effect of
    special blocks such as "BEGIN {...}". "END" blocks are ignored.

METHODS
  new
    Creates a new indexer object. Optional parameters:

    default_package
      The default package to assume a subroutine is in if no package
      statement was found beforehand. Defaults to "main".

  default_package
    Get/set default package.

  parse
    Parses a given piece of code. Alternatively, you may pass in a
    "PPI::Node" or "PPI::Document" object.

    Returns a simple hash-ref based structure containing the packages and
    subs found in the code. General structure:

      {
        'Package::Name' => {
          subs => {
            subname1 => 1,
            subname2 => 1,
            ... more subs ...
          },
        },
        ... more packages ...
      }

SEE ALSO
    Implemented using PPI.

TODO
    Maybe other constructs that affect inheritance?

    Exporting! (yuck)

    Other accessor generators.

    Moose. This is going to be tough, but mandatory.

    "Class-"import(...)> is currently not handled akin to "use Class ...".

    General dependency resolution.
