YALR

YALR (Yet Another LR parser generator) is a Rust library for generating LALR(1) parsers.

IMPORTANT: YALR is early work in progress and currently in an early prototypical state. Here be dragons.

Features

• Straightforward syntax - no custom grammar files, only Rust code and macros
• Tooling included - Parser introspection tooling included (LALR parse table, LALR state diagram)
• Lexer-independent - Works with any lexer that implements the Lexer trait

Build

Rust >= 1.31.0 is required to build YALR.

Usage

Examples can be found in the examples directory.
