Bencher::Scenario::Sort::HashKeys - Benchmark Sort::HashKeys
This document describes version 0.002 of Bencher::Scenario::Sort::HashKeys (from Perl distribution Bencher-Scenario-Sort-HashKeys), released on 2023-01-17.
To run benchmark with default option:
% bencher -m Sort::HashKeys
To run module startup overhead benchmark:
% bencher --module-startup -m Sort::HashKeys
For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run bencher --help.
bencher --help
Packaging a benchmark script as a Bencher scenario makes it convenient to include/exclude/add participants/datasets (either via CLI or Perl code), send the result to a central repository, among others . See Bencher and bencher (CLI) for more details.
Version numbers shown below are the versions used when running the sample benchmark.
Sort::HashKeys 0.007
map (perl_code)
Code template:
state $h = <hash>; map {($_, $h->{$_})} sort keys %$h
Sort::HashKeys::sort (perl_code)
state $h = <hash>; Sort::HashKeys::sort(%$h)
2key
10key

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, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
