Emacs
Racket mode
I use racket-mode.
I find it useful to disable smart bracket completion, because it does not play well with typesetting formulas. This requires some lines in my ‘Emacs‘ file:
(define-key racket-mode-map (kbd "]") nil) |
(define-key racket-mode-map (kbd ")") nil) |
(define-key racket-mode-map (kbd "}") nil) |
Emacs preview inspired by AUCTeX
The additional library bystroTeX-preview.el provides some rudimentary preview functionality similar to AUCTeX.
For example, see my .emacs file (search for racket-mode).
