Function Details

cachepath(f, tail=`''`, root=`''`)

source code

OBSOLETE: Return a pathname suitable for cacheing some result.

Parameters:

f (often str, but could be anything convertible to a str via repr.) - An arbitrary key, could be a pathname or a tuple of information about a file.
tail (str or None) - something to add at the end of the constructed path.

Returns: tuple(str, str)

(path_to_root,path_with_tail). Path_to_root is/will be a directory; path_with_tail is a path to a data file within that directory. Normally, the actual cache is at the location os.path.join(path_to_root,path_with_tail) on the disk; that is what you would pass as the fname argument to load_cache or dump_cache.

Raises:

ValueError - if suffix_to_del is specified and f doesn't end that way.
