NAME
Bencher::Scenario::TSVParsingModules - Benchmark TSV parsing modules
VERSION
This document describes version 0.001 of Bencher::Scenario::TSVParsingModules (from Perl distribution Bencher-Scenario-TSVParsingModules), released on 2019-04-23.
SYNOPSIS
To run benchmark with default option:
% bencher -m TSVParsingModules
To run module startup overhead benchmark:
% bencher --module-startup -m TSVParsingModules
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.

Text::CSV_XS (perl_code)
Code template:
my $csv = Text::CSV_XS->new({binary=>1, sep_char=>"\t", quote_char=>undef, escape_char=>undef}); open my $fh, "<", <filename>; my $rows = []; while (my $row = $csv->getline($fh)) { push @$rows, $row }
