It's the dark horse of this release as CLI parsing can also be more easily built on top of it. There's a couple of proposals floating around now, so I hope we get something soon-ish (maybe in 0.18 since a short cyle is planned for 0.17).
The idea is to offer some kind of CLI parsing in the std. It says minimal, but the discussion also veers into some more advanced options.
The discussion resulted in two PRs (that I know of):
- Type-driven: https://codeberg.org/ziglang/zig/issues/30677
@dotcarmen extracted it into a package (https://codeberg.org/dotcarmen/clip) so people could more easily try it out.
- Composition-based: https://codeberg.org/ziglang/zig/pulls/31620
If you're familiar with Rust's clap, it's a bit like derive vs builder API.
You can also see how each approach would look in practice if you inspect the diff for the "tools" directory on the PRs.
