|
;; Org-Babel support for evaluating haskell source code. This one will
|
|
;; be sort of tricky because haskell programs must be compiled before
|
|
;; they can be run, but haskell code can also be run through an
|
|
;; interactive interpreter.
|
|
;;
|
|
;; For now lets only allow evaluation using the haskell interpreter.
|
|
|
|
;;; Requirements:
|
|
|
|
;; - haskell-mode :: http://www.iro.umontreal.ca/~monnier/elisp/#haskell-mode
|

;; - inf-haskell :: http://www.iro.umontreal.ca/~monnier/elisp/#haskell-mode
