Installation

We provide precompiled binaries for Linux, MacOS and Windows on the Releases page. Make sure to copy it somewhere under your PATH environment variable (e.g. ~/.local/bin on Linux).

Building from Source

zig build install -Doptimize=ReleaseSafe --prefix ~/.local/

Tested using zig 0.13.0.

Usage

By default glsl_analyzer communicates over stdin/stdout:

glsl_analyzer

However, you can configure it to use a specific port (TCP) using the following command:

glsl_analyzer --port <PORT>

Neovim

nvim-lspconfig comes with support for glsl_analyzer. Simply add the following to your lua config:

require'lspconfig'.glsl_analyzer.setup{}

Visual Studio Code

Install the glsl-analyzer extension from the marketplace. It will automatically download the latest precompiled binary for your platform.
