see ISPC files have a .ispc extension for source, and a .isph extension for headers.
What issue are you seeing?
Image Image Image

would like to mention https://github.com/openai/codex/commit/726689564aa7ab938f40bfd94479d5b66c48c91b

by @etraut-openai which "Map .cu and .cuh extensions to the C++ syntax definition so CUDA source"
same should happen to popular relevant other type of compilers too as it follow mostly basic c++ syntax

also Yes, GitHub natively renders .ispc files
for example https://github.com/ispc/ispc/blob/main/examples/cpu/volume_rendering/volume.ispc

so its a common format

What steps can reproduce the bug?

prompt the codex with interesting things you have no clue about like compilers, or .ispc

What is the expected behavior?

No response

Research direction

Start by comparing the current extension handling with commit 726689564aa7ab938f40bfd94479d5b66c48c91b, which maps .cu and .cuh to C++ syntax. Trace the corresponding mapping for .ispc source and .isph headers, then verify that both extensions are rendered using C++ syntax without changing other formats.
