Thread Crash/Panic about pipes-rs HOT 6 CLOSED

Clap v4 must’ve changed how #[arg(value_parser)] works, since not only does --palette with any correct value trigger this panic, but so do --color-mode, --bold and --inherit-style. Clap has now released v5. Rather than erroneously upgrading without proper testing as happened with Clap v4, I propose we roll our own CLI argument parsing. @lhvy How do you feel about this?

After reading your comment, I was wondering why they already created a v5. But I couldn't find a v5 and there also doesn't seem to be a yanked release (the last one was v3.0.0-beta.3) https://crates.io/crates/clap/versions

You are, of course, completely right :) Turns out I saw v5 in the changelog, but yeah it looks like they haven’t released v5 anywhere. I’m not completely sure what’s up with that, though I’m sure there’s an explanation.

Clap recently did many refactorings and major breaking changes in order to get their API cleaned up and I would say they managed to do so. The crate is now much more mature, they managed to hide unwanted complexity behind feature flags and streamlined their API.

Thanks for the info! That’s good news, I’ll have to take a look at the changes.

Writing your own implementation of something hundreds of people racked their brains about will just resolve in much more maintenance work and new bugs for this project. IMO the better cause of action would be to help out with the development of clap instead.

Respectfully, I disagree. The tiny subset of Clap’s functionality strictly necessary for pipes-rs (short options, long options) is trivial to implement, and the rest isn’t much effort (Levenshtein distance-based typo correction, colored help output).

Sure. I should have some time soon. Should we decide on what we want to do from here and then fix this up?

@lhvy ?

I'm not involved into this project and just stumbled accross this issue, but rolling your own CLI argument parsing sounds like a bad idea. Clap recently did many refactorings and major breaking changes in order to get their API cleaned up and I would say they managed to do so.

@lhvy It occurred to me that, in the over-engineered spirit of this project, it might be nice to add automated tests for the command-line interface so these sorts of bugs can be caught in the future.
