PHP_ParserGenerator, a php 5 parser generator.
This is a direct port of the Lemon parser generator, found at http://www.hwaci.com/sw/lemon/
There are a few PHP-specific changes to the lemon parser generator.
- %extra_argument is removed, as class constructor can be used to
pass in extra information
- %token_type and company are irrelevant in PHP, and so are removed
- %declare_class is added to define the parser class name and any
implements/extends information
- %include_class is added to allow insertion of extra class information
such as constants, a class constructor, etc.
Other changes make the parser more robust, and also make reporting syntax errors simpler. Detection of expected tokens eliminates some problematic edge cases where an unexpected token could cause the parser to simply accept input.Otherwise, the file format is identical to the Lemon parser generator
