GLSL Major Mode

This is a major mode for Emacs providing editing conveniences for the OpenGL Shading Language (GLSL). It currently handles GLSL version 4.6, including many recent Vulkan extensions.

In brief, it provides the following features:

• Syntax high-lighting for symbols and built-in functions and variables.

• Indentation for the current line (<kbd>TAB</kbd>) and selected region (<kbd>C-M-</kbd>).

• Fast switching between 'file.vert' and 'file.frag' with ff-find-other-file (<kbd>S-iso-lefttab</kbd>).

• Interactive function glsl-find-man-page prompts for a GLSL built-in functions which it formats to an opengl.org URL and finally passes that to browse-url.

• An initial tree-sitter implementation.

Installation

The easiest way to install glsl-mode via MELPA, which can be setup with the following snippet:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "http://melpa.org/packages/"))
(package-initialize)

Once that is done, then just refresh the packages and install it with:

• <kbd>M-x package-refresh-contents</kbd>
• <kbd>M-x package-install glsl-mode</kbd>

Alternatively, you can also install the package using e.g. use-package with the following snippet in your .emacs:

(use-package glsl-mode
    :ensure t)
