Top 4 Rust parser-combinator Projects

nom

85 9,007 6.5 Rust

Rust parser combinator framework

Project mention: Planespotting with Rust: using nom to parse ADS-B messages | dev.to | 2023-10-28

Just in case you are not familiar with nom, it is a parser combinator written in Rust. The most basic thing you can do with it is import one of its parsing functions, give it some byte or string input and then get a Result as output with the parsed value and the rest of the input or an error if the parser failed. tag for example is used to recognize literal character/byte sequences.

Write expressive, high-performance parsers with ease.

Project mention: Lezer: A Parsing System for CodeMirror, Inspired by Tree-Sitter | news.ycombinator.com | 2024-03-24

I attempted to use this but was disheartened but the fact that it doesn't statically type node names. Tree Sitter doesn't either but it has much more of an excuse given that it targets C.

The dev seems mildly hostile to outside involvement too, so I moved on. These days I use Chumsky which is Rust rather than Typescript, but also way more awesome, if you can deal with the often incomprehensible compilation errors at least!
