Hey, I made an LSP for bgfx's shader language which has autocomplete and hover for its uniforms macros and whatnot.
https://github.com/r0ckHopper/bgfx_shader_analyzer
its a fork of glsl_analyzer with bgfx's spec hardcoded in.
Linking here if it is of interest to you.
Really love the zbgfx project, has helped me prototype quite fast.
