Linux::Event::Fork

Minimal async child process management on top of Linux::Event.

This module adds:

• Nonblocking stdout/stderr capture
• Streaming stdin
• Soft timeouts
• Tagging
• Bounded parallelism (max_children)
• Queueing
• drain() callback
• cancel_queued() support
• Introspection (running, queued, max_children)

It is intentionally small and policy-focused.

Quick Start

use v5.36;
use Linux::Event;
use Linux::Event::Fork;

my $loop = Linux::Event->new;

# Optional: configure bounded parallelism
my $fork = $loop->fork_helper(max_children => 4);

$loop->fork(
  cmd => [ $^X, '-we', 'print "hello\n"; exit 0' ],

  on_stdout => sub ($child, $chunk) {
    print $chunk;
  },

  on_exit => sub ($child, $exit) {
    print "exit code: " . $exit->code . "\n";
    $loop->stop;
  },
);

$loop->run;
