NAME Bencher::Scenario::INIParsingModules - Benchmark INI parsing modules VERSION This document describes version 0.002 of Bencher::Scenario::INIParsingModules (from Perl distribution Bencher-Scenario-INIParsingModules), released on 2022-08-10. SYNOPSIS To run benchmark with default option: % bencher -m INIParsingModules To run module startup overhead benchmark: % bencher --module-startup -m INIParsingModules For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run "bencher --help". DESCRIPTION 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. BENCHMARKED MODULES Version numbers shown below are the versions used when running the sample benchmark.

HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at . AUTHOR perlancar CONTRIBUTING 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. COPYRIGHT AND LICENSE This software is copyright (c) 2022, 2019 by perlancar .
