ShaderLab language support for Galacean Engine in Visual Studio Code.

• Syntax highlighting for .gs and .gsl
• Snippets for common ShaderLab structures
• Code completion for ShaderLab symbols and common built-ins
• Hover information
• Signature help
• Diagnostics
• Range formatting

This extension is designed for the main Galacean ShaderLab workflow, including:

• Shader, SubShader, Pass
• UsePass
• Editor, Properties, Macros, UIScript
• Header(...)
• Tags
• VertexShader, FragmentShader
• RenderQueueType
• BlendState, DepthState, StencilState, RasterState
• User-defined struct, functions, and variables
• Common preprocessor lines such as #include, #if, and #ifdef

Built-in snippets include:

• Shader
• SubShader
• Pass
• Editor
• Properties
• Macros
• UIScript
• UsePass
• Tags
• Header
• BlendState
• DepthState
• StencilState
• RasterState
• struct
• for
• if
• main

1. Install the extension.
2. Open a .gs or .gsl file.
3. Start writing ShaderLab code with highlighting, snippets, completion, and diagnostics.

Example:

Shader "Example/MyShader" {
  Editor {
    Properties {
      Header("Surface") {
        baseColor("Base Color", Color) = (1, 1, 1, 1);
        metallic("Metallic", Range(0, 1, 0.01)) = 0;
      }
    }

    UIScript "./ui.ts";
  }

  SubShader "Default" {
    Pass "Forward" {
      Tags { pipelineStage = "Forward" }
      VertexShader = vert;
      FragmentShader = frag;
    }
  }
}

pnpm install
npm run compile

To debug locally in VS Code:

1. Open this folder in VS Code.
