30.4.2 Other version/natural sort implementations

As previously mentioned, there are multiple variations on version/natural sort, each with its own rules. Some examples are:

• Natural Sorting variants in Rosetta Code.
• Python’s natsort package (includes detailed description of their sorting rules: natsort – how it works).
• Ruby’s version_sorter.
• Perl has multiple packages for natural and version sorts (each likely with its own rules and nuances): Sort::Naturally, Sort::Versions, CPAN::Version.
• PHP has a built-in function natsort.
• NodeJS’s natural-sort package.
• In zsh, the glob modifier ‘*(n)’ will expand to files in natural sort order.
• When writing C programs, the GNU libc library (‘glibc’) provides the strverscmp(3) function to compare two strings, and versionsort(3) function to compare two directory entries (despite the names, they are not identical to GNU Coreutils version sort ordering).
• Using Debian’s sorting algorithm in:
  • python: Stack Overflow Example #4957741.
  • NodeJS: deb-version-compare.
