realized i never really used jbanggpt because it was A) behind preview flag B) broken.

this fixes it, removes preview requirement + calls it JBang AI instead of GPT ...and introduce mechanism of picking a key from env and guess potential providers - incl. option of overriding it with JBANG_AI_* env.

should we add jbang config flags for them?

wdyt?

[quintesse]

Yes, I think it would be a good idea to provide flags. It will also give more attention to this feature when people run jbang init --help

[maxandersen]

implemented ai arggroup that uses environment/jbang options to look up values - @quintesse did i do that right ?

also moved file check to before ai call so you dont wait several seconds to then get rejected.

jbang init --ai-model=gpt-5.1 tetris.java implement tetris using whatever library that makes the most sense , javafx, libgdx or something else as long as its java using jbang syntax in one file.

i kinda wish we could come up with a way to detect ollama running locally but just a bit too many variants and models to make it worthwhile...user can always set the --ai-* config or env to make it work though.

plan to merge this if tests passes as its isolated change and would like a release out

[maxandersen]

i commented out providers i haven't had time to verify - just in case.
i moved the system prompt to a qute template + made it way more directed to increase likelihood of code actually working (but still not a gurantee - but still pretty damn good).

[quintesse]

Everything looks good, except for this, the default values don't start with "default.". THe fact that in the code you have to do:

defaultValue = "${JBANG_AI_PROVIDER:-${default.ai.provider)}"

is just an internal implementation detail.

Also, special chars are removed from the names. In this case you're using a . in the name, which is not valid. So the actual name becomes: aiprovider. (Although the fqn can also be used, which would be app.init.aiprovider, but in this case that's not very interesting/useful)

[quintesse]

You can't do default.ai.provider here, you have to use the fully qualified name (without special chars like I said earlier), so it becomes default.init.aiprovider.

And finally I see you have typos in those lines, you're using a ) instead of as }:

${JBANG_AI_PROVIDER:-${default.ai.provider)}
