lispy-eval reports "No buffer named ... "

[looselytyped]

I recently upgraded a few packages, and then e in lispy stopped worked. e in lispy-mode with CIDER reports nrepl-send-request: No buffer named com.mycompany.job

I set toggle-debug-on-error and came across this stacktrace

Debugger entered--Lisp error: (error "No buffer named com.mycompany.job")

Currently running GNU Emacs 24.5.1 with

cider 20150901.1605
lispy 20150901.550

Please let me know if there is anything else I can provide.

Two more points of note

• It seems that for some reason the name of the buffer is being returns as the full ns and not just the buffer name
• I am seeing the same behaviour with lispy-follow (F) - http://oremacs.com/lispy/#lispy-follow

This is a breakage in CIDER and it should be fixed there, I think. Even the most basic eval request fails now:

(nrepl-sync-request:eval
 "(+ 2 2)"
 (cider-current-ns)
 (nrepl-current-session))

@abo-abo - Thanks! I will post an issue there. Really appreciate the quick response.

However, I do believe that it has to do with the buffer name. My buffer name is job.clj - but (cider-current-ns) returns the namespace - not the name of the buffer. That's why I posted an issue here.

[bbatsov]

It's a breaking API change and it will stay as it currently is CIDER. We're decoupling nrepl-client from CIDER, which required this and many other similar changes. It's unfortunate, but unavoidable.

[bcarrell]

Looks like the signature just needs an update. @abo-abo should be able to fix it really quickly. If he's busy, I can send the PR.

[abo-abo]

Thanks, please test if it works correctly now.

Unfortunately, we're now incompatible with any version of CIDER that's different from the one that's in MELPA now.

@abo-abo I just tried it. Both e and F work in lispy.el! Thank you.
