||
;;; Commentary: | ||
|
||
;; Purpose: | ||
;; | ||
;; To send a Haskell buffer to another buffer running a Bot | ||
;; interpreter. | ||
;; | ||
;; This mode is derived from version 1.1 of Guy Lapalme's | ||
;; haskell-hugs.el, which can be obtained from: | ||
;; | ||
;; http://www.iro.umontreal.ca/~lapalme/Hugs-interaction.html | ||
;; | ||
;; This in turn was adapted from Chris Van Humbeeck's hugs-mode.el, | ||
;; which can be obtained from: | ||
;; | ||
;; http://www-i2.informatik.rwth-aachen.de/Forschung/FP/Haskell/hugs-mode.el | ||
;; | ||
;; | ||
;; Installation: | ||
;; | ||
;; To use with Moss and Thorn's haskell-mode.el | ||
;; | ||
;; http://www.haskell.org/haskell-mode | ||
;; | ||
;; add this to .emacs: | ||
;; | ||
;; (add-hook 'haskell-mode-hook 'turn-on-haskell-bot) | ||
;; | ||
;; | ||
;; Customisation: | ||
;; | ||
;; The name of the Bot interpreter is in haskell-bot-program-name. | ||
;; | ||
;; Arguments can be sent to the Bot interpreter when it is started by | ||
;; setting haskell-bot-program-args (empty by default) to a list of | ||
;; string args to pass it. This value can be set interactively by | ||
;; calling C-c C-s with an argument (i.e. C-u C-c C-s). | ||
;; | ||
;; `haskell-bot-hook' is invoked in the *bot* buffer once Bot is | ||
;; started. | ||
;; | ||
;; All functions/variables start with `turn-{on,off}-haskell-bot' or | ||
;; `haskell-bot-'. | ||
