# Naive search for unticked files. Has no semantic knowledge, just a lexical
# search for #include directives against existing file paths.
#
# Usage:
#  python unticked_files.py C:\Path\To\Paradise\
#
# Returns 0 if all existing files are considered ticked, 1 otherwise.

# When running in POSIX environments, the include paths in the codebase need to
# be munged into PureWindowsPaths before being spit back out. Otherwise, the
# checker will attempt to find files named e.g. /workspace/code\\foo.dm, which
# translates to the (completely legitimate) filename "code\foo.dm" in the
# /workspace directory.
#
# For more information, see the discussion of pure paths in the pathlib
# documentation.
