Top 22 Rust Text processing Projects

Text processing

  1. ripgrep

    ripgrep recursively searches directories for a regex pattern while respecting your gitignore

    Project mention: Zig, Rust, Go?! I tried 3 low-level languages and here’s what I’m sticking with | dev.to | 2025-08-28

    ripgrep (Rust project)

  3. sd

    Intuitive find & replace CLI (sed alternative)

    Project mention: Bzip2 crate switches from C to 100% rust | news.ycombinator.com | 2025-06-17

    There is sd, not a drop in replacement though.

    https://github.com/chmln/sd

  4. regex

    An implementation of regular expressions for Rust. This implementation uses finite automata and guarantees linear time matching on all inputs.

    Project mention: fd: A simple, fast and user-friendly alternative to 'find' | news.ycombinator.com | 2025-03-19

    Yes. I'm the one who implemented the case folding the `fd` uses (via its regex engine).

    See: https://github.com/rust-lang/regex/blob/master/UNICODE.md#rl...

    And then Unicode itself for more discussion on the topic: https://unicode.org/reports/tr18/#Simple_Loose_Matches

    TR18 used to have a Level 3[1] with the kind of locale-specific custom tailoring support found in GNU's implementation of POSIX locales, but it was so fraught that it was retracted completely some years ago.

  5. pomsky

    A new, portable, regular expression language

  6. Fluent

    Rust implementation of Project Fluent

  7. nucleo

    A fast and convenient fuzzy matcher library for rust

  8. aho-corasick

    A fast implementation of Aho-Corasick in Rust.

    Project mention: Oxidizing Ubuntu: adopting Rust utilities by default | news.ycombinator.com | 2025-03-21

    And when you put people on a pedestal, they're guaranteed to let you down. :-) https://github.com/BurntSushi/aho-corasick/commit/474393be8d...

    I wouldn't be surprised if that style of leak were more prevalent than one would expect. It's pretty subtle. But that link is the only such instance I'm aware of it happening to such a degree in crates I maintain. Maybe there are other instances. This is why I try to use `Box<[T]>` when possible, because you know that can't have extra capacity.
