Install

First you need to clone this repository and move gas-menu.el file to your load path and add the following code to your Emacs config file:

(require 'gas-mode)
(add-to-list 'auto-mode-alist '("\\.asm\\'" . gas-mode))

Now each time you open a file with .asm extension, gas-mode will be use automatically.

Customization

Variables can be changed through the customization menu or change its value in your Emacs config files.

gas-initial-indentation

This is an integer used to indent .section sections and tags to the 0 column by default but it can be changed to any other column you want.

gas-indentation

This is an integer use to indent any other lines not mentioned by the previous variable, e.g. the instructions or directive lines.

List of TODO improvements or features

• Keep improving indentation, tags can be tricky to indent since its use can be in single line (as memory address identifier for a value) or multi-line (as a memory address where a set of instructions begin or like the single line use)
• Add blinking and indentation to some nested directives like .macro. This idea is dropped since I noticed that I have to use either smie for this mode or make a custom function that evaluates all (or limited amount) the text before point after each keystroke searching for its respective close parenthesis (smie does this)
• Add support for company
