# Lark
|
|
|
|
A modern parsing library for Python
|
|
|
|
## Overview
|
|
|
|
Lark can parse any context-free grammar.
|
|
|
|
Lark provides:
|
|
|
|
- Advanced grammar language, based on EBNF
|
|
- Three parsing algorithms to choose from: Earley, LALR(1) and CYK
|
|
- Automatic tree construction, inferred from your grammar
|
|
- Fast unicode lexer with regexp support, and automatic line-counting
|
|
|
|
Lark's code is hosted on Github: [https://github.com/lark-parser/lark](https://github.com/lark-parser/lark)
