Is foreach not supported? What am I doing wrong?

See end of this section https://github.com/01mf02/jaq?tab=readme-ov-file#folding about foreach/3

@wader Thanks. Why advertise it as a jq clone and waste people's time though?

01mf02 commented 6 months ago

@oguz-ismail, I'm sorry to hear that you feel like your time has been wasted. However, jaq implement a sufficiently large set of jq features that I think that it warrants the name "jq clone". Furthermore, most "clones" are not completely identical to their originals, otherwise what would the point of a clone be?

I guess that some heuristics to warn when foreach/3 is used could have partially prevented your problem. However, I do currently not have the resources to implement such heuristics.

@01mf02 - Maybe "dialect" would help avoid confusion. That seems to be the compromise in the wikipedia article on jq.
