Question: Can AST transform back to GLSL codes? #1820

I have read the source code in this project and I know an example in the glslangvalidator.cpp to parser the GLSL codes into an AST. And now I want to know if the glslang project has achieved that AST can be transformed back to GLSL codes? Thank you.

Yes, this should be entirely possible, as the AST retains original type information.

Others have made tools that can cross between many languages, via SPIR-V. See for example https://github.com/KhronosGroup/SPIRV-Cross.
