Hyperlark

Hyperlark

A parsing toolkit usable from Rust, Python, C, and JS. It's fast, modular, and ergonomic.
Get started

Choose your language

Section titled “Choose your language”

Use Hyperlark in your favorite language. Or in several of them at once: The same grammar, and same semantics, will apply in each one.

Pythonimport hyperlark
Rustuse hyperlark::Lark
TypeScript / WASMimport { Lark }
C#include "hyperlark.h"

Why Hyperlark

Section titled “Why Hyperlark”

One grammar, four languages

Write a grammar in the industry-standard .lark language, and parse it from Python, Rust, JS/TS, or C. Hyperlark loads grammars at run-time, no compilation step necessary!

LALR and Earley

Choose between two very capable parsers, that complement each other’s abilities. Each parser comes with sophisticated lexers to choose from, and many useful improvements.

Fast & Safe

All language bindings run the Rust backend. It is fast, safe, and well-tested. See the benchmarks.
