perl-Pegex

Pegex::Parser is the Pegex component that provides the parsing engine runtime. It requires a Grammar object and a Receiver object. It's parse() method takes an input that is expected to be matched by the grammar, and applies the grammar rules to the input. As the grammar is applied, the receiver is notified of matches. The receiver is free to do whatever it wishes, but often times it builds the data into a structure that is commonly known as a Parse Tree.
