NAME

       Module::Extract::Use - Pull out the modules a module explicitly uses

SYNOPSIS

               use Module::Extract::Use;

               my $extor = Module::Extract::Use->new;

               my @modules = $extor->get_modules( $file );
               if( $extor->error ) { ... }

               my $details = $extor->get_modules_with_details( $file );
               foreach my $detail ( @$details ) {
                       printf "%s %s imports %s\n",
                               $detail->module, $detail->version,
                               join ' ', @{ $detail->imports }
                       }

DESCRIPTION

       Extract the names of the modules used in a file using a static analysis. Since this module
       does not run code, it cannot find dynamic uses of modules, such as "eval "require
       $class"". It only reports modules that the file loads directly. Modules loaded with
       "parent" or "base", for instance, will will be in the import list for those pragmas but
       won't have separate entries in the data this module returns.

       new Makes an object. The object doesn't do anything just yet, but you need it to call the
           methods.

       init
           Set up the object. You shouldn't need to call this yourself.

       get_modules( FILE )
           Returns a list of namespaces explicity use-d in FILE. Returns undef if the file does
           not exist or if it can't parse the file.

           Each used namespace is only in the list even if it is used multiple times in the file.
           The order of the list does not correspond to anything so don't use the order to infer
           anything.

       get_modules_with_details( FILE )
           Returns a list of hash references, one reference for each namespace explicitly use-d
           in FILE. Each reference has keys for:

                   namespace - the namespace, always defined
                   version   - defined if a module version was specified
                   imports   - an array reference to the import list
                   pragma    - true if the module thinks this namespace is a pragma

           Each used namespace is only in the list even if it is used multiple times in the file.
           The order of the list does not correspond to anything so don't use the order to infer
           anything.

       error
           Return the error from the last call to "get_modules".

TO DO

       •   Make it recursive, so it scans the source for any module that it finds.
