🔧 Build Guide

System Requirements

CMake 3.26+
C++17-compatible compiler

Build Steps

Clone the repository (including submodules):

git clone --recursive https://github.com/ComingToy/glslx.git  
cd glslx

Configure and build the project:

cmake -DENABLE_OPT=OFF -B build -S .  
cmake --build build --parallel

Install (optional):

sudo cp build/src/glslx /usr/local/bin/

📖 Usage

Neovim (coc.nvim) Configuration Example

Edit the coc.nvim configuration file ~/.config/nvim/coc-settings.json:

{  
  "languageserver": {  
    "glslang": {  
      "command": "/usr/local/bin/glslx",  
      "filetypes": ["glslx"]  
    }  
  }  
}

Compilation Command Configuration:
Create a compile_commands_glslx.json file in the project root, following the Compilation Database Specification. Example:

[  
  {  
    "directory": "/path/to/project",  
    "command": "glslc --target-env=vulkan1.3 -DInputType=float16_t -o output.spv -I /path/to/includes source.comp",  
    "file": "/path/to/project/source.comp",  
    "output": "output.spv"  
  }  
]
