Backend Support

CrossGL Translator keeps source imports and target code generators in separate registries. A language can be available as an input source, an output target, or both.

Built-in targets

Target	Backend name	Aliases	Output extension
DirectX / HLSL	directx	hlsl, dx	.hlsl
OpenGL / GLSL	opengl	glsl, ogl	.glsl
Metal	metal	metal	.metal
Vulkan SPIR-V	vulkan	spirv, spv	.spirv
CUDA	cuda	cu	.cu
HIP	hip	hip	.hip
Mojo	mojo	mojo	.mojo
Rust	rust	rust, rs	.rs
Slang	slang	slang	.slang

Built-in sources

Source	Registry name	Extensions	Reverse CrossGL generation
CrossGL	cgl	.cgl	Native source format
DirectX / HLSL	directx	.hlsl	Yes
OpenGL / GLSL	opengl	.glsl	Yes
Metal	metal	.metal	Yes
Vulkan SPIR-V	vulkan	.spv, .spirv	Yes

Mojo	mojo	.mojo	Yes
Rust	rust	.rs, .rust	Yes
Slang	slang	.slang	Yes

Runtime discovery

The public helpers crosstl.supported_backends() and crosstl.supported_sources() return the names registered in the current process. Plugin modules under crosstl.backend can add more source or target entries at runtime.
