Issue 44412: Add os.path.fileuri() function (original) (raw)

Proposal:

• Introduce os.path.fileuri() function that produces a 'file://' URI
• Adjust PurePosixPath.to_uri() to call posixpath.fileuri()
• Adjust PureWindowsPath.to_uri() to call ntpath.fileuri()
• Adjust nturl2path.pathname2url() to call ntpath.fileuri()

Rationale:

• pathlib is 95% a wrapper around os and os.path. It implements little itself except the OOP interface. as_uri() is one of only a tiny handful of pathlib features that have no decent antecedents.
• the existence of these OS-specific features complicates pathlib's internals, necessitating the existence of OS-specific '_Flavour' classes that greatly complicate work on bpo-24132
• this is a useful feature with lots of stackoverflow posts. It seems silly to /require/ users to use pathlib for this, as the rest of their codebase may work just fine using traditional path manip.
