Feature request: slang-gfx backend #8089

Version/Branch of Dear ImGui:

Back-ends:

slang

Compiler, OS:

Motivation

I'm writing a personal project with imgui and slang-gfx, and I hope there could be official support for slang-gfx backend. In short, slang is a brand new shading language resembling HLSL, but has richer language features and can be compiled to mainstream backends like dxil, spir-v etc. . slang-gfx is the abstraction library of graphics APIs, supporting cross-platform backends.

An official implementation of slang backend could be helpful for slang and imgui users.

Details of implementation

I've implemented my personal slang backend(haven't decoupled from my project framework, but it should be easy to do so). If this proposal could be taken, I'd be glad to make a PR writing the implementation.

Concerns

The only concern I have is slang is still under fast iteration development, which exact version we use in this implementation should be decided.

Hello, thanks for your interest and links.

Until a technology is widespread/common enough and stable I would not want to take on hosting an official backend.

I would however encourage you to extract yours into one, following our conventions (eg: imgui_impl_slang.cpp filenames, same function names etc). We will link to it from the list of backends in wiki. If ever Slang becomes more popular and you want it we can later consider merging it into the main repository.
