This document describes version 0.005 of Acme::CPANModulesUtil::Bencher (from Perl distribution Acme-CPANModulesUtil-Bencher), released on 2022-11-30.




 gen_bencher_scenario(%args) -> [$status_code, $reason, $payload, \%result_meta]

Generate/extract Bencher scenario from information in an Acme::CPANModules::* list.

An Acme::CPANModules::* module can contain benchmark information, for example in Acme::CPANModules::TextTable, each entry has the following property:

   entries => [
           module => 'Text::ANSITable',
           bench_code => sub {
               my ($table) = @_;
               my $t = Text::ANSITable->new(
                   use_utf8 => 0,
                   use_box_chars => 0,
                   use_color => 0,
                   columns => $table->[0],
                   border_style => 'Default::single_ascii',
               $t->add_row($table->[$_]) for 1..@$table-1;
           # per-function participant
           functions => {
               'func1' => {
                   bench_code_template => 'Text::ANSITable::func1([])',

The list also contains information about the benchmark datasets:

 bench_datasets => [
     {name=>'tiny (1x1)'    , argv => [_make_table( 1, 1)],},
     {name=>'small (3x5)'   , argv => [_make_table( 3, 5)],},
     {name=>'wide (30x5)'   , argv => [_make_table(30, 5)],},
     {name=>'long (3x300)'  , argv => [_make_table( 3, 300)],},
     {name=>'large (30x300)', argv => [_make_table(30, 300)],},

This routine extract those information and return a Bencher scenario structure.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • cpanmodule* => perl::modname

    Name of Acme::CPANModules::* module, without the prefix.

Returns an enveloped result (an array).

First element ($status_code) is an integer containing HTTP-like status code (200 means OK, 4xx caller error, 5xx function error). Second element ($reason) is a string containing error message, or something like "OK" if status is 200. Third element ($payload) is the actual result, but usually not present when enveloped result is an error response ($status_code is not 2xx). Fourth element (%result_meta) is called result metadata and is optional, a hash that contains extra information, much like how HTTP response headers provide additional metadata.

Return value: (any)

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.
