About

Language definition of the OpenGL Shading Language (GLSL) for the TeX package listings.

The language keywords are mainly taken from stef-levesque/vscode-shader .

Usage

1. Download or link this file to the LaTeX project.
2. Include language definition.

Example

% ...
\usepackage{listings}
% ...

\input{listings-glsl.prf}
% optionally set GLSL as default language
\lstset{language=GLSL}

\begin{document}
% ...

\begin{lstlisting}[language=GLSL, caption={Vertex Shader}]
#version 150

in vec3 in_pos;

uniform mat4 model;
uniform mat4 view;
uniform mat4 proj;

void main() {
	gl_Position = proj * view * model * vec4(in_pos, 1.0);
}
\end{lstlisting}
