Fixed

• replace usage of isnan with std::isnan which fixes the build on NetBSD

[3.1.0] - 2023-06-02

Changed

• added keyword argument pad to Hamming distance. This controls whether sequences of different length should be padded or lead to a ValueError
• improve consistency of exception messages between the C++ and pure Python implementation
• upgrade required Cython version to Cython==3.0.0b3

Fixed

• fix missing GIL restore when an exception is thrown inside process.cdist
• fix incorrect type hints for the process module

[3.0.0] - 2023-04-16

Changed

• allow the usage of Hamming for different string lengths. Length differences are handled as insertions / deletions
• remove support for boolean preprocessor functions in rapidfuzz.fuzz and rapidfuzz.process. The processor argument is now always a callable or None.
• update defaults of the processor argument to be None everywhere. For affected functions this can change results, since strings are no longer preprocessed. To get back the old behaviour pass processor=utils.default_process to these functions. The following functions are affected by this:
  • process.extract, process.extract_iter, process.extractOne
  • fuzz.token_sort_ratio, fuzz.token_set_ratio, fuzz.token_ratio, fuzz.partial_token_sort_ratio, fuzz.partial_token_set_ratio, fuzz.partial_token_ratio, fuzz.WRatio, fuzz.QRatio
• rapidfuzz.process no longer calls scorers with processor=None. For this reason user provided scorers no longer require this argument.
• remove option to pass keyword arguments to scorer via **kwargs in rapidfuzz.process. They can be passed via a scorer_kwargs argument now. This ensures this does not break when extending function parameters and prevents naming clashes.
• remove rapidfuzz.string_metric module. Replacements for all functions are available in rapidfuzz.distance

Added

• added support for arbitrary hashable sequence in the pure Python fallback implementation of all functions in rapidfuzz.distance
• added support for None and float("nan") in process.cdist as long as the underlying scorer supports it. This is the case for all scorers returning normalized results.

Fixed

• fix division by zero in simd implementation of normalized metrics leading to incorrect results

Performance

• add bitparallel implementation to InDel Distance (Levenshtein with the weights 1,1,2) for strings with a length > 64
• improve bitparallel implementation of uniform Levenshtein distance for strings with a length > 64

[1.1.0] - 2021-02-21

Changed

• string_metric.normalized_levenshtein supports now all weights
• when different weights are used for Insertion and Deletion the strings are not swapped inside the Levenshtein implementation anymore. So different weights for Insertion and Deletion are now supported.
• replace C++ implementation with a Cython implementation. This has the following advantages:

Changed

• string_metric.normalized_levenshtein supports now the weights (1, 1, N) with N >= 1

Performance

• The Levenshtein distance with the weights (1, 1, >2) do now use the same implementation as the weight (1, 1, 2), since Substitution > Insertion + Deletion has no effect

Fixed

[1.0.0] - 2021-02-12

Changed

• all normalized string_metrics can now be used as scorer for process.extract/extractOne
• Implementation of the C++ Wrapper completely refactored to make it easier to add more scorers, processors and string matching algorithms in the future.

• improved docstrings of functions

Performance

• Added specialized implementation of the Levenshtein distance for cases with a small maximum edit distance, that is even faster, than the bit-parallel implementation.
• Improved performance of fuzz.partial_ratio -> Since fuzz.ratio and fuzz.partial_ratio are used in most scorers, this improves the overall performance.
• Improved performance of process.extract and process.extractOne

Deprecated

• the rapidfuzz.levenshtein module is now deprecated and will be removed in v2.0.0 These functions are now placed in rapidfuzz.string_metric. distance, normalized_distance, weighted_distance and weighted_normalized_distance are combined into levenshtein and normalized_levenshtein.

Added

• added normalized version of the hamming distance in string_metric.normalized_hamming
• process.extract_iter as a generator, that yields the similarity of all elements, that have a similarity >= score_cutoff

• fixed bug in token_ratio

[0.14.1] - 2020-12-13

Fixed

• when a custom processor like lambda s: s was used with any of the methods inside fuzz.* it always returned a score of 100. This release fixes this and adds a better test coverage to prevent this bug in the future.

[0.14.0] - 2020-12-09

Added

• added hamming distance metric in the levenshtein module

Performance

• improved performance of default_process by using lookup table

[0.13.4] - 2020-11-30

Fixed

• Add missing virtual destructor that caused a segmentation fault on Mac Os

[0.13.3] - 2020-11-21

Added

• C++11 Support
• manylinux wheels

[0.13.2] - 2020-11-21

Fixed

• Levenshtein was not imported from __init__
• The reference count of a Python Object inside process.extractOne was decremented to early

[0.13.1] - 2020-11-17

Performance

• process.extractOne exits early when a score of 100 is found. This way the other strings do not have to be preprocessed anymore.

[0.13.0] - 2020-11-16

Fixed

• string objects passed to scorers had to be strings even before preprocessing them. This was changed, so they only have to be strings after preprocessing similar to process.extract/process.extractOne

Performance

• process.extractOne is now implemented in C++ making it a lot faster
• When token_sort_ratio or partial_token_sort ratio is used inprocess.extractOne the words in the query are only sorted once to improve the runtime

Changed

• process.extractOne/process.extract do now return the index of the match, when the choices are a list.

Removed

• process.extractIndices got removed, since the indices are now already returned by process.extractOne/process.extract

[0.12.5] - 2020-10-26

Fixed

• fix documentation of process.extractOne (see #48)

[0.12.4] - 2020-10-22

Added

• Added wheels for
  • CPython 2.7 on windows 64 bit
  • CPython 2.7 on windows 32 bit
  • PyPy 2.7 on windows 32 bit

[0.12.3] - 2020-10-09

Fixed

• fix bug in partial_ratio (see #43)

[0.12.2] - 2020-10-01

Fixed

• fix inconsistency with fuzzywuzzy in partial_ratio when using strings of equal length

[0.12.1] - 2020-09-30

Fixed

• MSVC has a bug and therefore crashed on some of the templates used. This Release simplifies the templates so compiling on msvc works again

[0.12.0] - 2020-09-30

Performance

• partial_ratio is using the Levenshtein distance now, which is a lot faster. Since many of the other algorithms use partial_ratio, this helps to improve the overall performance

[0.11.3] - 2020-09-22

Fixed

• fix partial_token_set_ratio returning 100 all the time

[0.11.2] - 2020-09-12

Added

• added rapidfuzz.__author__, rapidfuzz.__license__ and rapidfuzz.__version__

[0.11.1] - 2020-09-01

Fixed

• do not use auto junk when searching the optimal alignment for partial_ratio

[0.11.0] - 2020-08-22

Changed

• support for python 2.7 added #40
• add wheels for python2.7 (both pypy and cpython) on MacOS and Linux

[0.10.0] - 2020-08-17

Changed

• added wheels for Python3.9

Fixed

• tuple scores in process.extractOne are now supported #39
