Hello, In the current incarnation Pathlib is missing some key features I need in my usecases. I want to contribute them but i'd like a bit of feedback on the new api before jumping to implementation.
The four things I need are: #1. A context manager for temporary files and dirs (that cleans everything up on exit). Eg: with pathlib.TmpDir(suffix='', prefix='') as tmp: assert isinstance(tmp, pathlib.Path) with pathlib.TmpFile(suffix='', prefix='') as tmp: assert isinstance(tmp, pathlib.Path) #2. A context manager for changing working directory (that switches to the old cwd on exit). Eg: with path.cd(): assert os.getcwd() == path # 3 . Shutil-like features: - copy_file - copy_dir (or copy_tree?) - copy (does copy_dir or copy_file depending on what the source is. How to handle symlinks?) - rm_dir (or rm_tree? Also, this would be required for the TmpDir path). #4. Zip files support. A specialised Path subclass that works inside a zip file. I'm ok having this as an external package but some discussion would be useful as I'd have to rely on pathlib internals. After some brief looking in the pathlib code it would appear the wise thing would be to have the zip path as the "drive" for the ZipPaths that refer to files inside the zip. I'm not sure where the best place is to store the internal zipfile object. Perhaps the accessor? Ideally the ZipFiles would work with the shtuil-like api just fine (or at least the readonly operations). Thanks, -- Ionel M.
