SimpleParse is a Python module that provides a simple and fast parser generator using a modified version of the mxTextTools text-tagging engine. SimpleParse allows you to generate parsers directly from your EBNF grammar.
Unlike most parser generators, SimpleParse generates single-pass parsers (there is no distinct tokenization stage), an approach taken from the predecessor project (mcf.pars) which attempted to create "autonomously parsing regex objects". The resulting parsers are not as generalized as those created by, for instance, the Earley algorithm, but they do tend to be useful for the parsing of computer file formats and the like (as distinct from natural language and similar "hard" parsing problems).
As of version 2.1.0 the SimpleParse project includes a patched copy of the mxTextTools tagging library with the non-recursive rewrite of the core parsing loop. This means that you will need to build the extension module to use SimpleParse, but the effect is to provide a uniform parsing platform where all of the features of a give SimpleParse version are always available.
