Sibling Projects

There are ports of TatSu to Go and Rust. They are functionaly complete with except for features (like synthetic classes) that rely on the dynamic nature of Python.

铁修 TieXiu

铁修 TieXiu is the port of TatSu to Rust. It features a PyO3 interface os it's also a Python library, but the benchmarks show that the pure-Python parsers generated by TatSu are still more performant when hosting from Python. See the TieXiu README for a discussion of the performance limits of PEG parsers.

⻰OGoPEGo

⻰OGoPEGo is the port of TatSu to Go. The implementation, being the most mature, is beutifully concise, and using the generated parsers has a simplicity closer to the Python style allowed by TatSu.

Internals

  • The algorithm for left-recursion analysis went over another round of simplification and optimization. Then the analysis done in pegen, a more efficient and theoretically-sound approach, was evaluated. All tests pass with the pegen's SCC (Strongly Connected Componets) algorithm, so the old-and-tried algorithm in TatSu was replaced.

    Although left-recursion analysis is performed once per Grammar, before any parsing, a simpler implementation makes this core part of TatSu easier to maintain.
