support for GL_EXT_debug_printf

[rcmz]

Best vscode glsl extension that I found !
Unfortunately it does not like the string literals used in GL_EXT_debug_printf
This is detected as an error but compiles fine debugPrintfEXT("global thread id %v3u\n", gl_GlobalInvocationID);

Hello, what are your arguments given to glslang ? It seems some flags are missing for glslang to work correctly with Vulkan currently. From here, EShMsgVulkanRules & EShMsgSpvRules should be set for vulkan, that might be some of what's missing, but even with this fix, it does not work. I need to look more into it.

In fact, looking into this again, it seems to be related to character escaping, remove \n, everything is fine on my side. I will look if I can fix the escaping that must be done twice or something similar.

Oh yes indeed it is only the \n that is causing issue.
Thanks for taking a look at this

Hello again, I looked into it again, and it is a bug with the C API of glslang which I am using with rust bindings. I have filed an PR there, that hopefully will get merged and that should fix the issue !

Thanks ! The rabbit hole goes deeper
