I wrote up some ReShade 'code snippets' for use in Visual Studio Code.
Currently there are snippets for uniforms, ReShade specific intrinsics, pixel-shader prototypes, for loops, techniques and passes, and some other stuff.
I will likely update it from time to time.
And (maybe) even make a proper extension in the future.
Get it here:
