VSCode-mc-shader is a [Visual Studio Code](https://code.visualstudio.com/) extension for developing Minecraft GLSL Shaders for [Optifine](http://optifine.net). It currently provides linting and syntax highlighting (by stef-levesque/vscode-shader dependency).

## Features

- Linting
- Syntax highlighting (by extension dependency)
- Support for `#include` directives
- Auto-complete prompts (incomplete and rough)

## Installation (assumes installing from VSCode extension tab)

- After reloading, open a shaderpack's folder.
- You should be prompted to set your shaderpacks folder e.g. `"mcglsl.shaderpacksPath": "C:/Users/Noah/AppData/Roaming/.minecraft/shaderpacks"`
- You should then be prompted saying `glslangValidator` isn't installed. Hit the download button and wait for a notification saying that it's been installed.
- You should now be good to go!

## Requirements

- Visual Studio Code (v1.23.0 or higher - minimum requirement untested).
- The [Shader languages support for VS Code](https://marketplace.visualstudio.com/items?itemName=slevesque.shader) extension. This should automatically install when you install this extension.
- That the shader(s) you're editing are in the `shaderpacks` folder in `.minecraft`.
- That you've only one shader folder open. Multiple workspaces aren't currently supported.
- The [OpenGL / OpenGL ES Reference Compiler](https://github.com/KhronosGroup/glslang). The extension will give you an option to download it and update your settings automatically.

## Extension Settings

| Option Name | Data Type | Description | Default Value |
| ----------- | --------- | ----------- | ------------- |
| `mcglsl.glslangValidatorPath` | string |  The path to the glslangValidator executable. | In your `PATH`.|

## Contributing

Please see [CONTRIBUTING.md](https://github.com/Strum355/vscode-mc-shader/blob/master/CONTRIBUTING.md).

## Planned

- Multi-workspaces (currently only one is supported and using multiple is very undefined behaviour)
- Warnings for unused uniforms/varyings
- Some cool `DRAWBUFFERS` stuff
