This is intended for use in test files, to make path constants easier to read and write. Limitations: * Only supports Index, Key, BuildableFnOrCls, and Attr. * Key.key must be a string, and may not contain nested quote marks. Args: path_str: A string that would be returned by `daglish.path_str(p)` for some path p. Returns: A Path `p` such that `daglish.path_str(p) == path_str`. zR\.(?P\w+)|\[(?P\d+)\]|\[(?P\'[^\']*\'|\"[^\"]+\")\]|(?P.)attr __fn_or_cls__indexkeyzUnable to parse path z at ) recompilefinditergroupappendrBuildableFnOrClsAttrIndexintKey ValueErrortuple)r make_path_repathmr"Z/home/ubuntu/sommelier/.venv/lib/python3.10/site-packages/fiddle/_src/testing/test_util.py parse_paths     r$rootr cCst|t|S)z(Build a diffing.Reference from a string.)r Referencer$)r%r r"r"r#parse_referenceFsr' structurecs.tdtjdtffdd }t||S)abReturns the set of paths for each shared object in `structure`.
