Changes for version 1.967_004 - 2012-02-07

  • Localize the OUT filehandle during Precompile.
  • Document the <autotree:Base::Class> form of the <autotree> directive.
  • Provide a simple test for the <autotree> directive, t/autotree.t. Renamed basics.t to ensure it runs before autotree.t.
  • Allow a global <skip:> directive that functions the same as modifying $Parse::RecDescent::skip prior to compiling a grammar. (Thanks Flavio!)
  • Require that the $file returned by caller() be eq '-', rather than merely starting with '-'. This allows execution of the following. (Thanks Christopher) perl -MParse::RecDescent -e 'print "$Parse::RecDescent::VERSION\n";'
  • Warn on empty productions followed by other productions. The empty production always matches, so following productions will never be reached.
  • *** NON-BACKWARDS COMPATIBLE CHANGE! *** A repetition directive such as 'id(s /,/)' correctly creates a temporary @item variable to hold the 'id's that are matched. That @item variable is them used to set the real $item[] entry for that repetition. The same treatment is now given to %item. Formerly, in a production like:
    • id ',' id(s /,/)
    • matched against:
      • xxx, yyy, zzz
    • The $item{id} entry which should be 'xxx' is overwritten by 'yyy' and then 'zzz' prior to the action being executed. Now 'yyy' and 'zzz' set $item{id}, but in the private %item, which goes out of scope once the repetition match completes.
  • ** EXPERIMENTAL ** When precompiling, optionally create a standalone parser by including most of the contents of Parse::RecDescent in the resulting Precompiled output.
    • Accept an optional $options hashref to Precompile, which can be used to specify $options->{-standalone}, which currently defaults to false.
    • The subroutines import, Precompile and Save are not included in the Precompile'd parser.
    • The included Parse::RecDescent module is renamed to Parse::RecDescent::_Runtime to avoid namespace conflicts with an installed and use'd Parse::RecDescent.
    • Add a new t/precompile.t to test precompilation.
    • Add a new $_FILENAME global to Parse::RecDescent to make it easy for the Precompile method to find the module.
    • Remove the prototype from _generate. It is not required, and it caused t/precompile.t (which ends up re-definiing a lot of Parse::RecDescent subroutines) to fail needlessly, as the calls to _generate in Replace and Extend normally do not see the prototype, but do when re-defined.
    • POD documentation for standalone parsers added.
