Overview Parse::RecDescent incrementally generates top-down recursive-descent text parsers from simple *yacc*-like grammar specifications. It provides: * Regular expressions or literal strings as terminals (tokens), * Multiple (non-contiguous) produc...

Original FAQ You can see the original FAQ (still useful) at Parse::RecDescent::FAQ::Original. It is a document that I grew over about a decade, but I no longer have time for editing and categorizing other people's posts to fit them into POD format an...

Parse::RecDescent has a mechanism for automatically generating parse trees. What this does is to bless each resulting node into a package namespace corresponding to the rule. This might not be desirable, for a couple of reasons: * You probably don't ...

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 aro...

A common need when writing grammars is to know how much text was consumed at different points in a parse. Usually, this involves a lot of brain-twisting unwinding of of highly nested list-of-lists (of lists...). Instead this module allows you to take...

This module makes it easy to visualise Parse::RecDescent grammars. Writing Parse::RecDescent grammars is tricky at the best of times, and grammars almost always evolve in ways unforseen at the start. This module aims to visualise a grammar as a graph...

Takes a Parse::RecDescent grammar and converts it into a graph. You can write the result in any format supported by Graphviz <http://www.graphviz.org/>. Here is the list of output formats <http://www.graphviz.org/content/output-formats>....

This module provides a method "new" to build hashref objects for autotree classes. See Parse::RecDescent::Topiary for details. new Basic hashref style object constructor. Takes a list of value pairs....

The SQL parser is a Parse::RecDescent parser generated by Genezzo::Parse::SQLGrammar. It shouldn't be looked at with human eyes. Still reading this? You must be a glutton for punishment. This parser handles a fair bit of SQL92, but the error handling...
