Currently working on a compiler and simulator for a quantum programming language, using Gtk2Hs as the visualization tool.
2 Haskell mode for XEmacs
I use Haskell mode for emacs on XEmacs. So far, on all the linux systems that I have tried it on (admittedly, only Ubuntu and Debian), there is a system function missing that interferes with automatic indenting. Secondly, there seems to be an issue with setting the haskell default face to nil.
To fix this, find where the haskell mode package is installed on your system. (Usually
/usr/share/emacs/site-lisp/haskell-mode). Edit the file
haskell-indent.el and add the lines:
(eval-and-compile ;; If `line-end-position' isn't available provide one. (unless (fboundp 'line-end-position) (defun line-end-position (&optional n) "Return the `point' of the end of the current line." (save-excursion (end-of-line n) (point)))))
right after the comments at the top. That should fix the issue.
2.2 haskell-default-faceThis one shows up when typing in code (at various spots - most often when typing a qualified function, such as
To fix this one, edit the file
haskell-font-lock.el. Look for the line that says:
(defvar haskell-default-face nil)
and change this to
(defvar haskell-default-face 'default)
In my version, this is line 168.
Then, look for the line that says:
(,qvarid 0 haskell-default-face)
and change it to
(,qvarid 0 (symbol-value 'haskell-default-face))
For me, this is line 326 of the file. YMMV - hope this helps.
