Based on Emacs' standard asm-mode with following differences:
- Coloring modified to 6502 asm syntax more closely
- Code column has fixed indentation of 20 spaces, allowing long label names in the first column
- Comment column is fixed to 26 spaces right of code column
- ! -directives are indented either to leftmost column or 4 spaces left of code
- Backspace deletes a single char or all tabs and spaces until beginning of line
- C-t is mapped to quick jump to code column
Copy file to your emacs' elisp folder and add following:
(load "~/.emacs.d/acme-mode")
(add-to-list 'auto-mode-alist '("\\.acme\\'" . acme-mode))
Replace .emacs.d with dir of your choice.
