Interesting to see combinator conditions on #typescript for CLI.
This is something that's hard to do in any CLI library. Easier with typed languages, but still can be complex. Very cool to see with #optique and their approach leveraging the type system. 😎

Why Optique? | Optique
Discover how Optique brings functional composition to TypeScript CLI development, enabling truly reusable parser components that other libraries can't match through configuration-based approaches.

Hot take: We shouldn't block AI companies from training on our F/OSS code.
We should require them to free the models they train.
That's not naïve idealism—it's the same strategy that built GNU/Linux. Why training copyleft might be our GPL moment:

if people no longer read the code, API is no longer targeting humans, is there still a need for "good API design"? is it still worth the effort to figure out what would be the best for users, instead of the best of ai to understand/use? I don't know.

When building CLI tools, shell completion usually treats each option in isolation. But sometimes valid values for one option depend on another—like branch names depending on which repository you're targeting.

Your CLI's completion should know what options you've already typed
Consider Git's -C option:
