orderings
Ordering enumeration and protocols.
Decision gist · record as of 2026-08-14
Yes, if you are writing classes that need full comparison support and prefer a single compare method over six dunder methods. The low install friction, permissive MIT license, and lack of security issues make it safe to add. The dormant maintenance is not a blocker for a stable, narrow-scope library, but verify that the Compare protocol integrates well with your existing type hierarchy before committing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or above.
- Low friction: pure Python wheel with only two lightweight runtime dependencies.
- Dormant maintenance since June 2024, though repository remains active and marked Production/Stable.

What it is and what it does
orderings is a small library that centralizes comparison logic by providing an Ordering enumeration and a Compare protocol. Instead of implementing six separate comparison methods (`__eq__`, `__lt__`, etc.), you define a single `compare` method that returns an Ordering value, and the Compare protocol automatically derives all comparison operations from it. This is particularly useful when you already have a natural ordering function and want to avoid boilerplate.
The package depends on typing-aliases and typing-extensions to support type hints across Python 3.8 and newer. It is fully typed and marked Production/Stable, though development has been dormant since mid-2024. The library is small and self-contained, making it a low-risk addition for projects that benefit from a unified comparison interface.
Use it for
- Implement comparison for custom classes by writing one compare method instead of six dunder methods.
- Build ordered wrapper types that delegate comparison to an inner value using the Compare protocol.
- Simplify comparison logic where a natural ordering function already exists.
- Reduce boilerplate in data structures that need full ordering support but have a single comparison rule.
