Add a regular expressions library to the distribution #3591
Description
The exact engine we use needs further discussion. Probably we don't want to use yarr because it requires the nitro jit, which is a big dependency and could be undesirable for various reasons. Ideally, we would have a nice syntax extension that precompiles the regexes (in addition to runtime compilation options).

What about writing a regular expression engine in Rust?
brson commentedon Sep 25, 2012
That could be fine.
erickt commentedon Sep 28, 2012
For anyone who stumbles across this issue looking for a regex library, we do have a pcre binding in cargo.

@erickt is that related to @uasi's https://github.com/uasi/rust-pcre ?
erickt commentedon Oct 5, 2012
@killerswan neat! that seems to be an independent implementation. I'll ping @uasi to merge our code.

(also, as I mention elsewhere but apparently not in this bug, I prefer re2 for this)

(bug triage) Milestone is correct; could be a good medium-sized starter project for somebody.

I'm still interested in this. Been working on an cre2 binding. Not 100% sure how to handle functions that expect c enums.

I would like to claim this issue to do as a project for my university class.
nickdesaulniers commentedon Nov 1, 2013
@ktt3ja , I haven't been working on this.

I've been working on this, but it's pretty slow going. See https://github.com/glennsl/rust-re
It has a good set of features already, but is currently pretty naively implemented, horribly slow and not very nice to look at. I'm trying to learn rust as I go, and am currently trying to figure out how to optimize it without wandering into unsafe territory.
Feel free to fork it or implement something completely separate. A different perspective would just be good as far as I'm concerned.

There is a wiki page summarising some research about this: https://github.com/mozilla/rust/wiki/Lib-re
ktt3ja commentedon Nov 7, 2013
Nvm, I'll be working on something else for my project.
ferristseng commentedon Dec 7, 2013
I've been working on this for my class. The project is here https://github.com/ferristseng/regex-rust. I've been trying to add the features outlined in the ECMA-262 standard. If anyone has any suggestions or would like to help, let me know (this is my first time working on a regular expression engine).
