Directory Localizer helps you localize directories.
Periodically, you’ll want to know where a Python source file is actually
located on disk. You might want this for all sorts of reasons, and it’s
always a bit messy when you do want to know.
DirectoryLocalizer solves two problems:
- it lets you know where you are on disk, assuming you’re not
anywhere crazy, like in a zip import, and
- it lets you pass that location to other code that might want
to know where you are.
Usage is extremely simple:
- Make a DirectoryLocalizer object, dl (or whatever).
- Call dl.set() from the file you want to locate on disk.
- Any code that can access dl can now call:
- dl.dir(): for the directory of the file where dl.set()
- dl.path(fn): for the filename of a file in the directory
where dl.set() was called,
- dl.file(fn): for a file object of the file in dl.path(fn), and
- dl.read(fn): to get a read of the file in d.file(fn).
