A bare bones Emacs major mode for Uxntal, the programming language of the Uxn stack-machine.
I have tried to replicate the Sublime Text highlight rules already included in Uxn but multiline comments are not supported yet. I have never written an emacs mode before, so please be kind <3
Contributions welcomed!
The following configuration has been tested with a vanilla .emacs.d. Trying to get things working under prelude raised issues I was unable to address at the moment.
;; Uxntal
;;; Set location of uxntal-mode.el
(add-to-list 'load-path "~/.emacs.d/site-lisp")
;;; Make sure uxnasm and uxnemu are on your PATH if you want to use uxntal-eval-buffer.
;;; Include any other assemblers if you want to use them, for example ruxnasm.
;;; On OSX we need to set the exec-path.
;;; In linux it appears that if you have the executables in your shell's PATH you can probably skip this step.
(setq exec-path (append exec-path '("/Users/xyz/uxn/bin" "/Users/xyz/ruxnasm/target/release")))
;;; If you want to use a different assembler
(setq uxntal-assembler "ruxnasm")
;;; Enable the mode and associate with the .tal extension
(require 'uxntal-mode)
(add-to-list 'auto-mode-alist '("\\.tal\\'" . uxntal-mode))| binding | command | description |
