gdshader-lsp-cpp

The only active, feature-complete language server for GDShader — the shading language of the Godot Engine — implemented natively in C++.

If you write shaders for Godot in an external editor, this is the missing piece: full editor intelligence for .gdshader files through any LSP-capable editor.

Highlights

• Feature complete — the most complete GDShader language server available today
• Native C++ core — fast completion, hover and diagnostics even in large shader codebases
• Editor agnostic — works with VS Code, Neovim, Helix, Zed, and anything else that speaks LSP
• Actively maintained — bugs get fixed, the Godot shader spec gets tracked

Features

• Autocompletion for shader functions, built-ins and uniforms
• Hover documentation for GDShader built-ins
• Diagnostics and syntax validation
• Go-to-definition and symbol search
• Signature help

Getting started

Grab the latest release from the repository and point your editor’s LSP client at the binary. Configuration examples for popular editors live in the README.
