This emacs mode adds basic syntax highlighting and indentation support for DCPU-16 assembly.
To use dcpu16-mode place the file dcpu16-mode.el in your load-path and add the line
(require 'dcpu16-mode)
to your .emacs file. If you don't have a load path set up, you can create a directory:
mkdir ~/.emacs.d
And add the line:
(add-to-list 'load-path "~/.emacs.d/")
to your emacs file, above the require line.
To use the mode, open a DCPU-16 assembly file and invoke:
M-x dcpu16-mode
This major mode includes two things:
- Syntax Highlighting
- Indentation Rules
Syntax highlighting rules exist for lables, comments, instructions and register names.
The indentation rules are fairly simple. Any comment, label or blank line is not indented. Every instruction is indented to a default of 8 spaces.
To change this default, the set-variable command can be used:
M-x set-variable RET indentation-spaces [number of spaces] RET
This is a first attempt at creating a major mode, so there might be some issues. Know issues include:
Indentation after a label
Currently, if an instruction is on the same line as a label, indentation must be done manually by adding spaces.
Comment highlighting
Adding a ';' character at the start of line with existing instructions may not change the highlight to be a comment
