Parent relative shader includes

[tomdrinKEENSWH]

Hello,
we have previously used SharpDX where shader compiler's include handler had following signature:
Stream Open(IncludeType type, string fileName, Stream parentStream)

This reference to parentStream allowed us to obtain parent filepath and therefore to implement relative includes.
For example:

• entry.hlsl with "#include ../file2.hlsli"
• ../file2.hlsli with "#include ../file3.hlsli" //there the relative path to entry.hlsl is ../../file3.hlsl

In Vortice the Include Handler api is simpler:
Result LoadSource(string includeFileName, out IDxcBlob? includeSource)

Would you consider adding the SharpDX style Include handlers?
Is there a clean way how to implement the described behaviour using current Include handlers?

What you're talking is the legacy FXC include handler (ID3DInclude), the implementation in Vortice is based on IDXCIncludeHandler.
So the concept/usage are different and you should look at DirectXShaderCompiler usage.
