Rust Onig

Build Status Build status

Rust bindings for the Oniguruma regex library, a powerful and mature regular expression library with support for a wide range of character sets and language syntaxes. Oniguruma is written in C. This repository provides two crates: onig-sys which provides the raw Rust FFI bindings, and onig, which provides a safe Rust wrapper around them.

Documentation

Check out the module documentation to find out all the features that are available. To see some example usage of this crate take a look a the examples folder. The examples can be run from the command line with cargo run --example <examplename>.

Getting Started

Add the following to your Cargo.toml file:

[dependencies]
onig = "1.2"

Add the following extern to your crate root:

extern crate onig;

You can can compile simple regular expressions with Regex::new, check if the pattern matches an entire &str with Regex::is_match and find matches within a &str with Regex::find. The onig crate also supplies more powerful versions of these methods which expose the wide range of options Oniguruma provides.

use onig::*;

let regex = Regex::new("e(l+)").unwrap();
for (i, pos) in regex.captures("hello").unwrap().iter_pos().enumerate() {
    match pos {
         Some((beg, end)) =>
             println!("Group {} captured in position {}:{}", i, beg, end),
         None =>
             println!("Group {} is not captured", i)
    }
}
