NAME Bencher::Scenario::EnsuringAllPatternsInString - Ensuring all patterns are in a string VERSION This document describes version 0.020 of Bencher::Scenario::EnsuringAllPatternsInString (from Perl distribution Bencher-Scenario-EnsuringAllPatternsInString), released on 2024-02-11. SYNOPSIS To run benchmark with default option: % bencher -m EnsuringAllPatternsInString For more options (dump scenario, list/include/exclude/add participants, list/include/exclude/add datasets, etc), see bencher or run "bencher --help". DESCRIPTION This scenario is inspired by . I want to know how much faster/slower using the single regex with look-around assertions is compared to using multiple regex. As I expect, the single_re technique becomes exponentially slow as the number of patterns and length of string increases. 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. BENCHMARK PARTICIPANTS * single_re (perl_code) Uses look-around assertions. Code template: state $re = do { my $re = join "", map {"(?=.*?".quotemeta($_).")"} @{}; qr/$re/; }; =~ $re; * multiple_re (perl_code) Code template: state $re = [map {my $re=quotemeta; qr/$re/} @{}]; for (@$re) { return 0 unless =~ $_ } 1; BENCHMARK DATASETS * dataset BENCHMARK SAMPLE RESULTS Sample benchmark #1 Run on: perl: *v5.38.2*, CPU: *Intel(R) Core(TM) i5-7200U CPU @ 2.50GHz (2 cores)*, OS: *GNU/Linux Ubuntu version 20.04*, OS kernel: *Linux version 5.4.0-164-generic*.

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.
