✨ NAME ✨

Parallel::Pipes::App — a friendly interface for Parallel::Pipes 🎀

---

🦋 SYNOPSIS 🦋

bestie, look how easy this is:

use Parallel::Pipes::App;

my @result = Parallel::Pipes::App->map(
  num => 3,
  work => sub { my $task = shift; $task * 2 },
  tasks => [1, 2, 3, 4, 5],
);
# @result is ( 2, 4, 6, 8, 10 )

like… that's it. that's the whole vibe check. ✨

---

🌸 DESCRIPTION 🌸

Parallel::Pipes::App provides friendly interfaces for Parallel::Pipes. no gatekeeping, no cap, it just hands you the nice version 💖

---

👑 METHODS 👑

Parallel::Pipes::App provides 2 class method:

lowkey iconic that there's only two. fewer things to remember, more brain cells for you 🧚

💜 map

my @result = Parallel::Pipes::App->map(
  num => $num,
  work => $work,
  tasks => \@task,
);

So it processes @task by $work in $num pre-forked child processes, and you get @result back. This is almost the same as:

my @result = map { $work->($_) } @task;

except — and this is the main character detail — $work gets executed in a child process, not in the current process. that's the whole point, that's the slay 🔥

🌈 run

Parallel::Pipes::App->run(
  num => $num,
  work => $work,
  tasks => \@task,
  before_work => $before_work,
  after_work => $after_work,
);

run is the more generic form of map. like, the bigger sister method. In fact, we can write map by using run:

my @result;
Parallel::Pipes::App->run(
  num => $num,
  work => $work,
  tasks => \@task,
  before_work => sub {},
  after_work => sub { push @result, $_[0] },
);

see what they did there?? map is literally just run wearing a cute outfit 💅 iykyk
