librashader
A preprocessor, compiler, and runtime for RetroArch 'slang' shaders, rewritten in pure Rust.
Heavily WIP.
License
There is not yet a functioning implementation of librashader but this section outlines its licensing goals in contrast to RetroArch.
While librashader is an independent reimplementation of the RetroArch shader pipeline, referencing the RetroArch source code was indispensable to its creation. As it is therefore considered a derivative work, the core parts of librashader such as the preprocessor, the preset parser, the reflection library, and the runtimes, are all licensed under GPLv3.
The librashader C API, i.e. its headers and definitions, not its implementation in librashader_capi
,
are unique to librashader and are more permissively licensed, and may allow you to use librashader in your permissively
licensed or proprietary project.
While the code for librashader_capi
(librashader.so
and rashader.dll
) is still under GPLv3,
you may use librashader in a non-GPL work by linking against the MIT licensed librashader_ld
,
which implements the librashader C API, and thunks its calls to any librashader.so
or rashader.dll
library found in the load path, provided that librashader.so
or rashader.dll
are distributed under the restrictions
of GPLv3.
Note that if your project is not compatible with GPLv3, you can not distribute librashader.so
or rashader.dll
alongside your project, only librashader-ld.so
or rashader-ld.dll
, which will do nothing without a librashader
implementation in the load path. The end user must obtain the implementation of librashader themselves.
