I'm curious, when executing a function using the -X switch, the JVM never exits, I have to put an explicit (System/exit 0) or similar. That's a bit surprising. I would have thought that as soon as the function has exited, the JVM would shut down.

does it stop after about 30 or 60 seconds?

Yes

daemon?

yeah its the agent threadpool i believe. you can call the really cool-named function (shutdown-agents).

trying

yeah, the thing is that when you thread multiple functions and the non-last function calls that, it might screw things up :)

yup

but perhaps the "wrapper" of this thread could call it as the last op

that works

I wonder if that could be added to the docs, i.e., as a little bit of useful information? Others trying this out may also wonder why the function isn't exiting, until 60 or so seconds have passed.

it's a common thing with CLI apps/scripts

that's already been added in the current prerelease

so you won't need to do this

ooh

fantastic

@dharrigan Update your CLI. That has been fixed.

Oh, I see Alex already said that. Sorry, just catching up 🙂

@alexmiller I was trying out the -X:deps help/doc thing, and I can get it to give me help for a whole :ns but when I try to get help for a single function, I just get

(! 1036)-> clojure -X:deps:uberjar help/doc :fn hf.depstar/pom
-------------------------

(! 1037)-> clojure -X:deps:uberjar help/doc :fn pom :ns hf.depstar
-------------------------

The following works:

(! 1038)-> clojure -X:deps:uberjar help/doc :ns hf.depstar
Entry point for clojure -X options.

-------------------------
hf.depstar/aot
([options])
  -X entry point for AOT compilation.
... lots of help for every function ...

@seancorfield only fixed on a pre-release

Either qualified :fn or :ns is supposed to work

Please file a jira if you have a repro that doesn’t work

I'll stick it up on ask for others to vote for it, and you can create a Jira in whichever is the appropriate project...

(I initially thought it might just be a problem with stuff brought in via an alias but apparently not)
