Emacs + clojure. Autocompletion data from all source files in project

Question

I've been developing C# applications for a long time. Commercial IDEs and tools provide extremely good code completion features. I'm now learning clojure and I really miss familiar workflow. So, about emacs. I've installed nrepl, ac-nrepl and clojure-mode. Auto completion works fine in repl. It also works for symbols in current buffer. But not for: - symbols from other project files - external libraries (managed with leiningen). Is there any existing package that fully covers cases 1 and 2? My clojure-related config: ``` ;;;;;;;;;;;;;;; ;;; clojure ;;; ;;;;;;;;;;;;;;; (require 'nrepl) ;; Configure nrepl.el (setq nrepl-hide-special-buffers t) (setq nrepl-popup-stacktraces-in-repl t) (setq nrepl-history-file "~/.emacs.d/nrepl-history") ;; Some default eldoc facilities (add-hook 'nrepl-connected-hook (defun pnh-clojure-mode-eldoc-hook () (add-hook 'clojure-mode-hook 'turn-on-eldoc-mode) (add-hook 'nrepl-interaction-mode-hook 'nrepl-turn-on-eldoc-mode) (nrepl-enable-on-existing-clojure-bu…

Accepted Answer

After installing a fresh nrepl and ac-nrepl, here is what I put into the .emacs

```
(package-initialize)
(require 'auto-complete)
(global-auto-complete-mode)
(add-hook 'nrepl-mode-hook 'ac-nrepl-setup)
(add-hook 'nrepl-interaction-mode-hook 'ac-nrepl-setup)
(add-hook 'clojure-nrepl-mode-hook 'ac-nrepl-setup)
```

When I now `nrepl-jack-in` into a test-project and open a file of it, I have tab-completion on every namespace currently loaded in the project. It seems like you forgot the `'ac-nrepl-setup` on the `'nrepl-interaction-mode-hook`.
