"You made a thing, but now you wish it'd go away... Deprecations, a love story."
Regret is a library for deprecating functionality in Python libraries and applications.
Its documentation lives on Read the Docs.
Regret can deprecate:
- [x] callables
- [x] functions
- [x] classes
- [ ] subclassable classes
- [ ] old-style classes
- [ ] attributes
- [ ] of modules
- [ ] of classes
- [ ] of old-style classes
- [ ] of instances
- [ ] descriptors
- [ ] classmethod
- [ ] modules
- [ ] arguments to callables
- [ ] required arguments that will be removed
- [ ] optional arguments that are now required
- [ ] mutual exclusion
- [ ] zope.interfaces
Regret is meant to cover all of the deprecations an author may encounter.
It is intended to:
- be versioning system agnostic (i.e. SemVer, CalVer, HipsTer, etc.)
- be documentation system agnostic, though potentially documentation system aware (i.e. Sphinx, epydoc, Plaintext, etc.)
- be itself fully tested
- support removal date indication, and likely “policies” which automate choosing default removal dates
- minimize the amount of deprecation-related code required for authors
In particular, as a lofty first milestone, it is intended to cover all of the specific deprecations required for these jsonschema issues, and with luck, to subsume all the functionality present in twisted.python.deprecate.
