Deprecation notice: These days you probably want to use ac-cider or Cider's built-in company completion support instead of this.
This plugin provides a completion source for the popular Emacs interactive auto-completion framework auto-complete.
Where nrepl provides it, pop-up documentation for completed symbols will be displayed.
Latest stable version: see the latest numbered tag, which will also be the latest version available via Marmalade.
First, ensure auto-complete and cider are installed: I recommend using packages from Marmalade or Melpa.
You'll need both auto-complete and cider to be enabled and working, so please consult the corresponding documentation if you have any trouble with this.
Next, install ac-nrepl. If you choose not to use the convenient package in Melpa and Marmalade, you'll need to add the directory containing ac-nrepl.el to your load-path, and then (require 'ac-nrepl).
ac-nrepl provides an nrepl-specific completion source, so auto-complete needs to be told to use them when cider-repl-mode is active. To do this, put the following code in your emacs init file to
(require 'ac-nrepl) (add-hook 'cider-repl-mode-hook 'ac-nrepl-setup) (add-hook 'cider-mode-hook 'ac-nrepl-setup) (eval-after-load "auto-complete" '(add-to-list 'ac-modes 'cider-repl-mode))
If you want to trigger auto-complete using TAB in nrepl buffers, you may want to put auto-complete into your completion-at-point-functions:
(defun set-auto-complete-as-completion-at-point-function () (setq completion-at-point-functions '(auto-complete))) (add-hook 'auto-complete-mode-hook 'set-auto-complete-as-completion-at-point-function) (add-hook 'cider-repl-mode-hook 'set-auto-complete-as-completion-at-point-function) (add-hook 'cider-mode-hook 'set-auto-complete-as-completion-at-point-function)
You might consider using ac-nrepl's popup documentation in place of nrepl-doc:
(eval-after-load "cider" '(define-key cider-mode-map (kbd "C-c C-d") 'ac-nrepl-popup-doc))
ac-nrepl should now automatically be enabled when you visit a buffer in which cider-repl-mode is active and auto-complete is enabled. (The symbols "nrepl and "AC" should appear in the modeline.)
Simply trigger auto-completion, and completion candidates supplied by nrepl should be displayed, with symbols on the right hand side of the completion pop-up to indicate the "flavour" of the completion candidate, e.g. "v" for variables. After a short delay, popup documentation for the completed symbol should also be displayed.
ac-nrepl was written by Steve Purcell, with important contributions from Sam Aaron.
