rapidfuzz/RapidFuzz v2.0.0

Release 2.0.0

on GitHub

Added

• added C-Api which can be used to extend RapidFuzz from different Python modules using any
  programming language which allows the usage of C-Apis (C/C++/Rust)
• added new scorers in rapidfuzz.distance.*
  • port existing distances to this new api
  • add Indel distance along with the corresponding editops function

Changed

• when the result of string_metric.levenshtein or string_metric.hamming is below max
  they do now return max + 1 instead of -1
• Build system moved from setuptools to scikit-build
• Stop including all modules in __init__.py, since they significantly slowed down import time

Removed

• remove the rapidfuzz.levenshtein module which was deprecated in v1.0.0 and scheduled for removal in v2.0.0
• dropped support for Python2.7 and Python3.5

Deprecated

• deprecate support to specify processor in form of a boolean (will be removed in v3.0.0)
  • new functions will not get support for this in the first place
• deprecate rapidfuzz.string_metric (will be removed in v3.0.0). Similar scorers are available
  in rapidfuzz.distance.*

Fixed

• process.cdist did raise an exception when used with a pure python scorer

Performance

• improve performance and memory usage of rapidfuzz.string_metric.levenshtein_editops
  • memory usage is reduced by 33%
  • performance is improved by around 10%-20%
• significantly improve performance of rapidfuzz.string_metric.levenshtein for max <= 31
  using a banded implementation
