libripgrep is not any one library, but rather, a collection of libraries that roughly separate the following key distinct phases in a grep implementation: 1. Pattern matching (e.g., by a regex engine). 2. Searching a file using a pattern matcher. 3. Printing results. Ultimately, both (1) and (3) are defined by de-coupled interfaces, of which there may be multiple implementations. Namely, (1) is satisfied by the `Matcher` trait in the `grep-matcher` crate and (3) is satisfied by the `Sink` trait in the `grep2` crate. The searcher (2) ties everything together and finds results using a matcher and reports those results using a `Sink` implementation. Closes #162

grep-pcre2
The grep-pcre2 crate provides an implementation of the Matcher trait from
the grep-matcher crate. This implementation permits PCRE2 to be used in the
grep crate for fast line oriented searching.
Dual-licensed under MIT or the UNLICENSE.
Documentation
NOTE: You probably don't want to use this crate directly. Instead, you
should prefer the facade defined in the
grep
crate.
If you're looking to just use PCRE2 from Rust, then you probably want the
pcre2
crate, which provide high level safe bindings to PCRE2.
Usage
Add this to your Cargo.toml:
[dependencies]
grep-pcre2 = "0.1"
and this to your crate root:
extern crate grep_pcre2;
