Description:
larkcython 0.0.15
Lark-Cython
Cython plugin for Lark, reimplementing the LALR parser & lexer for better performance on CPython.
Install:
pip install lark-cython
Usage:
import lark_cython
parser = Lark(grammar, parser="lalr", _plugins=lark_cython.plugins)
# Use Lark as you usually would, with a huge performance boost
See the examples for more.
Differences from Lark
Token instances do not inherit from str. You must use the value attribute to get the string.
Other caveats
Postlexer isn't currently implemented
Speed
In current benchmarks, lark-cython is about 50% to 80% faster than Lark.
We're still in the early stages, and in the future, lark-cython might go a lot faster.
