having a hard time using anything past 0.8.1 on my coworker's osx box, it looks a lot like https://github.com/clojure-emacs/cider/issues/671 but can't find any workarounds.

just hangs

deleting cider and clojure mode and reinstalling fixed my issues when upgrading to 0.9.1: https://github.com/clojure-emacs/cider/issues/1181

yea, this was a clean install

gtrak: Are you doing cider-connect or jack-in? If it's jack-in you could check the nrepl-server buffer for information.

Also, if it hangs indeinitely, do M-x toggle-debug-on-quit and hit C-g a good time into the hang.

@malabarba: it's cider-connect

Ok, then there's no nrepl buffer

I downgraded back to 0.8.1 and it was still a problem, downgrading tools.nrepl 0.2.10 to 0.2.6 fixed it

hm

but I see master is using 0.2.10 (and it works on linux) so I wonder how no one has hit this before

Did you try tools.nrepl 0.2.6 with cider 0.9.1?

I did not, spent too much time on this today . Need an osx box for testing.

Yes, this kind of thing can be time consuming :)

Anyway, try the debug-on-quit thing

cool, i'll look more into it next time around

It should tell us where the hang is happening, at least on the Emacs side

but I really do wonder if just 0.2.10 is somehow breaking things

and how that could be mac-specific

beats me :P

nah, using tools.nrepl 0.2.10 on osx here

I'm quite sure at least a couple of the Cider devs are on Mac (batsov himself is, IIRC), so the problem is certainly not as simple as that

Between profiles.clj, project.clj, and the different versions of each package (and of lein itself), there's a lot of room for problems :P

also using maven

and the manual startup with cider-nrepl handler

not sure if that makes it easier or harder to mess up 😉

@blueberry: To change the Cider REPL prompt, I have this:

(defvar nomis-cider-repl--prompt-prefix (cl-concatenate 'string
                                                        (make-string 80 ?\_) "\n"))

(defvar nomis-cider-repl--prompt-suffix "\n")

(setq cider-repl-prompt-function
      (lambda (namespace)
        (cl-labels ((do-it () (funcall 'cider-repl-default-prompt namespace)))
          (if nomis-cider-repl--hack-prompt-p
              (cl-concatenate 'string
                              nomis-cider-repl--prompt-prefix
                              (do-it)
                              nomis-cider-repl--prompt-suffix)
            (do-it)))))

@nomiskatz: cl-concatenate 'string is basically concat (I think)

@malabarba: Thanks — seems to be so.

Turns out I have uses of concat elsewhere. My Emacs Lisp is very varied — mostly it depends on where I happened to copy code from before I hacked it.

yep

that sounds about right

Every once in a while I dust off some .el files and find horrendous code in there

@nomiskatz there is a much simpler way. check the answer in the github issue I raised

@blueberry: Right. I was just trying to point you at cider-repl-prompt-function.
