santiago 0.1.1

Features

• ✔️ Crab friendly 🦀

  It's written in Rust, with zero dependencies, maximum portability.

• ✔️ Human friendly

  Built with a focus on ergonomics, defining a grammar is closely the same to its Backus–Naur form.

• ✔️ Powerful

  Santiago can parse all context-free languages, including ambiguous and recursive grammars.

• ✔️ Cutting-edge

  Santiago uses the Earley algorithm. Its time and space performance is close to the known theoretical minimum.

Getting started

Just checkout the examples:

• calculator

You can run the examples by cloning this project and executing:

/santiago $ cargo run --example calculator

Alternatives

Santiago aims to be an alternative to GNU Bison, Yacc and Flex.

Sadly those long standing tools do not offer Rust compatibility.

Short term goals

In order:

1. Enforce resolving ambiguities in the input grammar.

2. Implement a Flex-like interface for the lexer, so that you can really do complex lexing beyond 'char-by-char'

3. Release 1.0.0.
