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.
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>.
Add the following to your Cargo.toml file:
toml
[dependencies]
onig = "0.4"
Add the following extern to your crate root:
rust
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.
```rust 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) } } ```
