NAME

Parse::RecDescent::Deparse - Turn a Parse::RecDescent object back into its grammar

SYNOPSIS

   use Parse::RecDescent::Deparse;
 
   my $foo = new Parse::RecDescent($grammar);
   print $foo->deparse;
 
 

DESCRIPTION

This module adds the "deparse" method to the "Parse::RecDescent" class, which returns a textual description of the grammar.

Why? There are at least two equally unlikely reasons why this could be useful:

•

You're working on something which grovels around in the "Parse::RecDescent" object data structure and want to view the effects of your changes. For instance, a "Parse::RecDescent" optimizer. (This
 package does not contain a functional "Parse::RecDescent" optimizer.)

•

You want to understand how "Parse::RecDescent" does what it does, and fancy the source of this package is a bit more of a gentle introduction than the source of "Parse::RecDescent" itself.

BUGS

"Parse::RecDescent::Deparse" can correctly deparse the metagrammar for "Parse::RecDescent" input, so that's a good thing. There are no bugs in the "Parse::RecDescent" optimizer as it clearly does not exist.
