JLexPHP: a Lexical Analyzer Generator for PHP, based on JLex. For copyright and licensing information, see the COPYING file.

This is an adaptation of some Java code that generates lexers from lex style input files.

The porting effort was pretty trivial, with the hardest part being the buffer management.

Usage is fairly typical of lexers; you'll want to create a lexer file like this:

The syntax is described [here](http://www.cs.princeton.edu/~appel/modern/java/JLex/current/manual.html).

Requirements
------------

[](#requirements)

Parser that extends [`AbstractLexer`](lib/AbstractLexer.php) requires lexer generated by [JLexPHP](https://github.com/rnapoles/JLexPHP).

Install
-------
