nice, congrats on launch. To get an idea... what's the size of a standalone hello world cli binary?
tens of KBs (v small)
This looks useful. But, it's interesting how the backend-world and front-end world keep diverging. I must admit, I had no idea what this was from the title. "CLI framework"? But in backend-land, these would typically be called "argument parsers" or "command line argument parsers". But maybe I am missing some of the functionality.
good point.
we’re using “framework” intentionally because it goes beyond argument parsing. crust handles parsing, but also:
type inference across args + flags end to end compile-time validation (so mistakes fail before runtime) plugin system with lifecycle hooks (help, version, autocomplete, etc.) composable modules (prompts, styling, validation, build tooling) auto-generates agent skills and modules from the CLI definitions
so it sits a layer above a traditional arg parser like yargs or commander, closer to something like oclif, but much lighter and bun-native.
> Versions before 1.0 do not strictly follow semantic versioning.
Sorry for being nitpicky, but yes they do. Semantic versioning[0] allows arbitrary changes while the major version is 0:
> Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.
[0]: https://semver.org/
thanks for the catch, what we meant is that we’re not committing to strict stability guarantees yet, so APIs may still change as we iterate toward 1.0.
I understand, but that's already implied by a 0.y.z version number.
this is cool! i'd recommend fleshing out the README. Clicked on the link before the discussion and was a tad confused.
will fix in the next hour!
Psst, the GitHub link in your post is broken (it should be https://github.com/chenxin-yan/crust).
Fixed above. Thanks for the heads-up!
thanks for flagging! the post itself works, just the link at the bottom
Is there an examples section? Would be helpful to see a demo
one of the examples would be trynia.ai (search and index api for ai agents)
here is github: github.com/nozomio-labs/nia-cli
