# If the string "/__w/" is present in compile commands (as part of a path of

# previous step of the action was done in a container-based GitHub action with
# a custom image.
# As a result, we have to rewrite all of the paths in the compile commands
# to not use the /__w path prefix and instead use /github/workspace as a path
# prefix so that hdoc can find the paths of the C++ files it analyzes.
# Why this is required:
# Unfortunately GitHub Actions doesn't persist workdir between steps of the
# same job so we have to resort to hacks like this. Furthermore, it doesn't
# even tell you what the previous path was so you have to do sketchy heuristics.
