Description
TatSu (the successor to Grako) is a tool that takes grammars in a variation of EBNF as input, and outputs memoizing (Packrat) PEG parsers in Python.
TatSu can compile a grammar stored in a string into a tatsu.grammars.Grammar object that can be used to parse any given input, much like the re module does with regular expressions, or it can generate a Python module that implements
the parser. TatSu has experimental support for left-recursive rules in PEG grammars using the algorithm by Laurent and Mens. The generated AST has the expected left associativity.
