Added

• A__version__ attribute relying onimportlib.metadata.
• Auv.lock lock-file for reproducible builds.

Changed

• Drop official support for Python 3.8.
• Switch fromblack toruff for code style.
• Fully migrate to apyproject.toml-based project.
• Ensure code style consistency (see selected rules inpyproject.toml).
• Extra dependencies are part of thedev dependency group (PEP 735).
• Switch fromsetuptools tohatchling for buildingportion.
• Switch fromcoverage topytest-cov for test coverage.

Added

• Thehow function ofcombine can access the current interval ifpass_interval is set (see#97).

Added

• Thecombine method of anIntervalDict accepts amissing parameter to fill values for non-overlapping keys (see#96).
• A recipe tocombine more than twoIntervalDict (see#95).

Changed

• Drop official support for Python 3.7.

Fixes import error increate_api for Python 3.10+ (see#87)

Fix import error when usingcreate_api outside a REPL (see#85).

Added

• AnAbstractDiscreteInterval class to ease the creation of specialized discrete intervals (experimental).
• Acreate_api function to generate an API similar to the one ofportion but configured to use a given subclass ofInterval (experimental, seeSpecialize & customize intervals).

Changed

• Speed uprepr andto_string forInterval instances (see#76, adm271828).
• Some internal changes to ease subclassing:
  • from_string andfrom_data accepts aklass parameter to specify which class should be used to createInterval instances (default isInterval).
  • Add aklass parameter foropen,closed,openclosed,closedopen,singleton andempty (default isInterval).
  • Add a_klass class attribute inIntervalDict to specify how to createInterval instances (default isInterval).
  • IntervalDict usesself.__class__ to preserve subclasses when creating new instances.

Changed

• Speed up lookups inIntervalDict for non-interval keys.
• Speed upiterate by no longer creating singleton instances under the hood.
• Drop official support for Python 3.6.

Fixed

• Infinite recursion when a subclass of anInterval is compared using> with anInterval instance (see#75).

Added

• Support Python 3.10.
• IntervalDict.as_dict has an optionalatomic=False parameter that, if set toTrue, returns intervals that are atomic.
• Experimental support for structural pattern matching (onleft,lower,upper andright).

Fixed

• (breaking) Setlist(P.empty()) == [], i.e., the empty interval is a disjunction of no interval (see#72).
• (breaking) For consistency, the empty interval is never<,>,<=, nor>= when compared to another interval.
• Comparing an interval and a value is deprecated since it is ill-defined when the value is on the left of<= or>=. Convert values to singletons first.

Added

• SupportPEP 517.

Changed

• Some internal changes to ease subclassingInterval(see#58):
  • Useself.__class__ instead ofInterval to create new instances;
  • Deprecate and movemergeable function toInterval._mergeable class method;
  • Interval.from_atomic is now a class method instead of a static method.
• Speed up lookups inIntervalDict (#65, Jeff Trull).
• Speed up removals inIntervalDict.
• Speed up intersection for non-overlapping intervals (#66, Jeff Trull).
• Speed up.overlaps and.contains for non-overlapping intervals/items.

Fixed

• from_stringraises aValueError if given string cannot be parsed to an interval (#57).

Changed

• Drop official support for Python 3.5.
• Useblack as official code formatting.
