Switch haskell-process-type between cabal-repl and ghci

Can I switch the haskell-process-type on during an alive haskell session or when starting a new session?

Solution

  • Yes, just type the following in a buffer and C-x C-e it afterwards (assuming cabal-repl is your default).

    (setq haskell-process-type 'ghci)

    In my .emacs I actually have this to make this easy, since I do this often:

    (define-key haskell-mode-map (kbd "C-c h t") 
  (lambda () (interactive)
    (progn
      (setq haskell-process-type 'ghci)
      (message "Now in ghci mode."))))

    Another C-c C-l will then load your interactive buffer with the correct mode.

    EDIT: Using haskell-mode-map now.
