💖 Dumbbench::Instance::PerlEval(3) — bestie edition 💖

okay so this is the Dumbbench::Instance::PerlEval page from the User Contributed Perl Documentation, and it's literally about benchmarking a lil string of Perl code. yes, that kind of benchmarking. timing your code so you can brag about it (or cry about it). no cap.

✨ NAME ✨

Dumbbench::Instance::PerlEval — Benchmarks a string of Perl code 💅

🌸 SYNOPSIS 🌸

use Dumbbench;

my $bench = Dumbbench->new(
  target_rel_precision => 0.005, # seek ~0.5%
  initial_runs         => 20,    # the higher the more reliable
);
$bench->add_instances(
  Dumbbench::Instance::PerlEval->new(name => 'mauve', code => 'for(1..1e9){$i++}'),
  # ... more things to benchmark ...
);
$bench->run();
# ...

not me writing a whole benchmark harness in like six lines. iconic behavior fr fr. 🎀

🦋 DESCRIPTION 🦋

This class inherits from Dumbbench::Instance and implements benchmarking of strings of Perl code using eval "". like, it takes your code-as-a-string and runs it over and over and times it. that's the whole vibe. 💜

👑 METHODS 👑

🌈 new

Constructor that takes named arguments. classic.

In addition to the properties of the base class, the Dumbbench::Instance::PerlEval constructor requires a code parameter. The code needs to be a string that is suitable for passing repeatedly to string-eval. yes bestie, it's a string, not a coderef, don't come at me.

Optionally, you can provide a dry_run_code option. It has the same structure and purpose as the code option, but it is used for the dry-runs. By default, a simple eval is used for this, so it's unlikely you will need the dry-run unless you want to strip out the compile-time overhead of your code. iykyk. ✨

🌸 code

Returns the code string that was set during construction. that's it. that's the method. 💅

🎀 dry_run_code

Returns the dry-run code string that was set during construction. short king method. 👑
