The Levenshtein Python C extension module contains functions for fast
computation of:
* Levenshtein (edit) distance, and edit operations
* string similarity
* approximate median strings, and generally string averaging
* string sequence and set similarity
NOTE: If this package has multiple flavors (see below), then use one of them instead of the name specified above. NOTE: This is a Python port. Instead of py311-Levenshtein listed in the above command, you can pick from the names under the Packages section.
devel/py-Levenshtein: fix build with libc++ 19
As noted in the libc++ 19 release notes [1], std::char_traits<> is now
only provided for char, char8_t, char16_t, char32_t and wchar_t, and any
instantiation for other types will fail.
This causes ports using devel/py-Levenshtein to fail to compile with
clang 19 and libc++ 19, resulting in errors similar to:
/usr/include/c++/v1/string:820:42: error: implicit instantiation of undefined
template 'std::char_traits<unsigned int>'
