Documentation pop-up only in repl, not in file buffers

[robinheghan]

Like the title says. I only get documentation (and function arguments) when in the repl buffer, not in source code. I do get general auto-completion though.

[purcell]

Which version are you using, and what corresponding configuration do you have in your emacs init files?

[robinheghan]

I using todays version on Melpa.

;; init.el

(require 'auto-complete-config) (require 'ac-nrepl) (ac-config-default) (add-hook 'cider-repl-mode-hook 'ac-nrepl-setup) (add-hook 'cider-interaction-mode-hook 'ac-nrepl-setup) (eval-after-load "auto-complete" '(add-to-list 'ac-modes 'cider-repl-mode))

(defun set-auto-complete-as-completion-at-point () (setq completion-at-point-functions '(auto-complete))) (add-hook 'auto-complete-mode-hook 'set-auto-complete-as-completion-at-point) (add-hook 'cider-repl-mode-hook 'set-auto-complete-as-completion-at-point) (add-hook 'cider-interaction-mode-hook 'set-auto-complete-as-completion-at-point)

Sometimes this can result from trying to auto-complete in a Clojure buffer which defines a namespace that has not yet been created, so you might just need to compile the file you're working on so that the namespace is fully defined.

[robinheghan]

Well, this is true for simple functions like "dec" or "defn" also :/ Btw, does this mean that I should AOT my clojure code to get auto-completion/docs?

[purcell]

No, but you should generally C-c C-k your files before working in them, so if you create a new file which defines a new namespace, you should hit C-c C-k after adding the (ns ...) form.

So can you confirm whether doing this makes a difference in your case?

[robinheghan]

I entered my source file. Used cider-jack-in, and C-c C-k. No difference. cider-doc works just fine though

[purcell]

Okay, cool. That gives me more to go on. And do you get any ac-nrepl completion results in the Clojure buffer? These would be results with the symbol "v", "c", "m", "n" or "s" on the right-hand-side of the auto-complete dropdown?

I had a similar problem. I think it's because cider-interaction-mode is now just cider-mode. Some things are aliased, but dropping the 'interaction' fixed it for me.

[purcell]

Thanks Neale. That would make sense. I just yesterday (?) updated the suggested ac-nrepl setup code to reflect this, because someone pointed out to me that the mode had been renamed.

[purcell]

Hey @bbatsov: it would probably make sense to just drop the cider-interaction-mode alias rather than risk breakage like this, if that is indeed the cause.

[bbatsov]

@purcell Will do! I've added the aliases with the idea to avoid breakages, but oddly enough they had the opposite effect. I guess mode aliases are problematic.

[robinheghan]

Changing from cider-interaction-mode to cider-mode did the trick, thanks for all help :)
