TatSu v4.2.5 released

Show key headers only | View raw

竜 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.

竜 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.

竜 TatSu fully supports left-recursive rules in PEG grammars using the
algorithm by Laurent and Mens. The generated AST has the expected left
associativity.
