# I'm sorry dear reader, unfortunately my knowledge of regex trumps my knowledge of
# Python. This pattern allows us to clean up file paths by stripping them down to
# just the relevant file name.

# The key can either be 'filepath' or 'buffer_name'. Also apply this logic to
# the file name in XML, which is written 'file=\"...\"'.
r'(key\.(?:filepath|buffer_name): |file=)'
# Open delimiter with optional escape.
r'\\?"'
# Lazily match characters until we hit a slash, then match any non-slash that
# ends in the right file extension, capturing the result.
r'.*?[/\\]+([^/\\]*\.(?:swiftmodule|swift|pcm|h))'
# For swiftmodule bundles, we want to match against the directory name, so
# optionally match the .swiftmodule filename here. The lazy matching of the
# previous logic means we'll prefer to match the previous '.swiftmodule' as the
# directory.
r'(?:[/\\]+[^/\\]*\.swiftmodule)?'
# Close delimiter with optional escape.
