Competent or not, slop is still slop. The website in particular uses the exact same copy-paste layout/style produced by LLMs and used by pretty much every slop project out there.
One very quick "slop or not?" test is to see if em dashes are used in the source code where they literally never make sense. It's not a great test, but it's one that consistently turns out to be good enough. The results should speak for themselves: https://github.com/search?q=repo%3Ajolt-lang%2Fjolt+%E2%80%9...
If you consider all AI generated text or code slop, then sure, the project's code is AI generated.
But in my case I think there are levels. In this case, the author has the expertise needed to properly design the work and assess the quality of the output. And it seems they intend to maintain and evolve the library actively and long term.
Would I prefer a serious Clojure on chez that's all hand-written, for sure, but beggars can't be choosers.
The website layout is the same one I used in projects like Luminus long before LLMs even existed https://luminusweb.com
If you have specific comments about the quality of the code then I'd be happy to discuss that. Attacking other people's work because they used tools you don't understand is just toxic trolling. And the fact that you judge code quality by the number of em dashes in the comments really speaks volumes.
Maybe spend a bit of time figuring out how to use new tools effectively instead of harping on what other people are doing.
It's very telling that whenever somebody starts braying about slop, they never have anything of substance to say. All the noise you add to discussions people are trying to have is the real slop.
Probably good to note that this person is building his own language: https://inko-lang.org/
