To enable the completion source this, put the following code in your emacs init file:
(require 'ac-haskell-process) ; if not installed via package.el (add-hook 'interactive-haskell-mode-hook 'ac-haskell-process-setup) (add-hook 'haskell-interactive-mode-hook 'ac-haskell-process-setup) (eval-after-load "auto-complete" '(add-to-list 'ac-modes 'haskell-interactive-mode))
If you want to trigger
auto-complete using TAB in REPL buffers, you may
want to put
auto-complete into your
(defun set-auto-complete-as-completion-at-point-function () (add-to-list 'completion-at-point-functions 'auto-complete)) (add-hook 'auto-complete-mode-hook 'set-auto-complete-as-completion-at-point-function) (add-to-list 'ac-modes 'haskell-interactive-mode) (add-hook 'haskell-interactive-mode-hook 'set-auto-complete-as-completion-at-point-function) (add-hook 'haskell-mode-hook 'set-auto-complete-as-completion-at-point-function)
You can use
ac-haskell-process-popup-doc to pop up documentation
for the symbol at point:
(eval-after-load 'haskell-mode '(define-key haskell-mode-map (kbd "C-c C-d") 'ac-haskell-process-popup-doc))
This currently requires that Emacs can execute the “hoogle” command.
ac-haskell-process should now automatically be enabled when you
visit a buffer in which
interactive-haskell-mode is active and
auto-complete is enabled. (Check the modeline.)
Simply trigger auto-completion, and completion candidates supplied by nrepl should be displayed, with the symbol “h” on the right hand side of the completion pop-up to indicate that the completion was provided by this source. After a short delay, popup documentation for the completed symbol should also be displayed.
