Sort::Sub::changes_group_ala_perlancar - Sort changes group heading PERLANCAR-style


This document describes version 0.092 of Sort::Sub::changes_group_ala_perlancar (from Perl distribution Sort-SubBundle-PERLANCAR), released on 2021-10-17.


Generate sorter (accessed as variable) via Sort::Sub import:

 use Sort::Sub '$changes_group_ala_perlancar'; # use '$changes_group_ala_perlancar<i>' for case-insensitive sorting, '$changes_group_ala_perlancar<r>' for reverse sorting
 my @sorted = sort $changes_group_ala_perlancar ('item', ...);

Generate sorter (accessed as subroutine):

 use Sort::Sub 'changes_group_ala_perlancar<ir>';
 my @sorted = sort {changes_group_ala_perlancar} ('item', ...);

Generate directly without Sort::Sub:

 use Sort::Sub::changes_group_ala_perlancar;
 my $sorter = Sort::Sub::changes_group_ala_perlancar::gen_sorter(
     ci => 1,      # default 0, set 1 to sort case-insensitively
     reverse => 1, # default 0, set 1 to sort in reverse order
 my @sorted = sort $sorter ('item', ...);

Use in shell/CLI with sortsub (from App::sortsub):

 % some-cmd | sortsub changes_group_ala_perlancar
 % some-cmd | sortsub changes_group_ala_perlancar --ignore-case -r


A Changes file can group its changes entries into groups with headings, e.g.:


 - blah blah

 - blah


 - blah blah blah

I sort these group headings according to this principle: prioritize the items that:

  • are more important;

  • affect users the most;

  • users would want to know first.

Thus breaking or backward-incompatible changes are put first because they affect existing users and in a significant way. Removed features are next, they are also basically backward-incompatible changes.

Then come new features. After that, enhancements. Bug fixes currently come last (actually bug fixes vary in importance but we currently do not categorize them further into subgroups).

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

 % prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
