NAME

       Perl::PrereqScanner::NotQuiteLite::Context

DESCRIPTION

       This is typically used to keep callbacks, an eval state, and found prerequisites for a
       processing file.

METHODS

   add
         $c->add($module);
         $c->add($module => $minimum_version);

       adds a module with/without a minimum version as a requirement or a suggestion, depending
       on the eval state. You can add a module with different versions as many times as you wish.
       The actual minimum version for the module is calculated inside (by
       CPAN::Meta::Requirements).

   register_keyword_parser, remove_keyword_parser, register_method_parser, register_sub_parser
         $c->register_keyword_parser(
           'func_name',
           [$parser_class, 'parser_for_the_func', $used_module],
         );
         $c->remove_keyword_parser('func_name');

         $c->register_method_parser(
           'method_name',
           [$parser_class, 'parser_for_the_method', $used_module],
         );

       If you find a module that can export a loader function is actually "use"d (such as Moose
       that can export an "extends" function that will load a module internally), you might also
       register the loader function as a custom keyword dynamically so that the scanner can also
       run a callback for the function to parse its argument tokens.

       You can also remove the keyword when you find the module is "no"ed (and when the module
       supports "unimport").

       You can also register a method callback on the fly (but you can't remove it).

       If you always want to check some functions/methods when you load a plugin, just register
       them using a "register" method in the plugin.

   requires
       returns a CPAN::Meta::Requirements object for requirements.

   suggests
       returns a CPAN::Meta::Requirements object for suggestions (requirements in "eval"s), or
       undef when it is not expected to parse tokens in "eval".

METHODS MOSTLY FOR INTERNAL USE

   new
       creates an instance. You usually don't need to call this because it's automatically
       created in the scanner.

   has_callbacks, has_callback_for, run_callback_for
         next unless $c->has_callbacks('use');
         next unless $c->has_callbacks_for('use', 'base');
         $c->run_callbacks_for('use', 'base', $tokens);

       "has_callbacks" returns true if a callback for "use", "no", "keyword", or "method" is
       registered. "has_callbacks_for" returns true if a callback for the module/keyword/method
       is registered. "run_callbacks_for" is to run the callback.

   has_added
       returns true if a module has already been added as a requirement or a suggestion. Only
       useful for the ::UniversalVersion plugin.
