## What it is
Shaderc is a collection of tools, libraries, and tests for compiling GLSL and HLSL shaders to SPIR-V for Vulkan. It includes glslc, a GCC/Clang-style command line compiler, and libshaderc, a C/C++ library API wrapping the same functionality.

## Use cases
- compile glsl shaders to spir-v for vulkan
- compile hlsl to spir-v from the command line
- integrate shader compilation into a build system
- compile shaders at runtime from a c++ application
- support shader #include files during compilation
- build shaders for android ndk projects

## When to choose
- you need a command-line shader compiler with gcc/clang-like flags for build integration
- you want a stable library API to compile shaders to SPIR-V at runtime
- you are targeting Vulkan and need glslang/SPIRV-Tools wrapped in one tool

## When to avoid
- you need HLSL compilation long-term, since HLSL support is deprecated upstream in Glslang
- you target DirectX or Metal rather than Vulkan/SPIR-V
- you need a full shader authoring or debugging IDE

## Facets
- artifact type: library
- maturity: stable
- function: compiler, cli, developer-tools
- domain: graphics, developer-tools, compilers
- platform: windows, cross-platform, cli
- tags: shader-compilation, spir-v, vulkan, glsl, hlsl, glslang, c++, game-development, linux, macos, android
