confusing error messages. about grenchman HOT 6 CLOSED

OK, so the main issue here is that you need two separate servers; one for project code and one for lein tasks. What you're doing is trying to re-use the project server as a Leiningen server, which doesn't work because your project doesn't know about Leiningen's namespaces.

The second example should work without setting GRENCH_PORT if you run grench from within the project dir.

But yeah, the error messages could probably be clearer here. Open to suggestions as to wording.

Ok, thanks - that clears it up somewhat.
But the headless repl I started was inside a project dir - so what you explained sounded exactly the other way round.

When I run

lein repl :headless

and in the same dir

~/bin/grench-0.2.0-debian-7 eval '(println 23)'

then I still need GRENCH_PORT=1234

So basically running clojure code is fine, but I can't get lein to work over grench - at all, with any task

from grenchman.

Ok, I see that you're running Leiningen 2.3.0. You need 2.3.3 for Grenchman.

from grenchman.

OK, so I changed nothing and I got it to work somehow.

• Leiningen 2.3.3 was already used, see above, I tried 2.3.0 and 2.3.3
• ~ $ lein repl :headless outside a project dir and I can use grench eval and grench lein anywhere, outside and inside a project dir
  • ~/project/ $ lein trampoline repl :headless inside a project dir, nothing works, not even ~/project/ $ grench lein version

from grenchman.

Right; launching a repl inside your project should not allow grench lein to work, because how would your project know what to do with Leiningen tasks?

from grenchman.

Yeah, now I got it.
I have no clue how, but I totally misunderstood http://leiningen.org/grench.html versus what I had learnt from IRC earlier - maybe my expectations were completely off.

So maybe the only thing is missing is a "why should I use it" paragraph on that page. Basically like the repo README.

Case closed, all is fine.

Thanks for your patience :)

(But it really did misbehave at the start, still confused a little)
