Proc::Guard(3p)

NAME
Proc::Guard - process runner with RAII pattern

SYNOPSIS
    use Test::TCP qw/empty_port wait_port/;
    use File::Which qw/which/;
    use Proc::Guard;

    my $port = empty_port();
    my $proc = proc_guard(scalar(which('memcached')), '-p', $port);
    wait_port($port);

    # your code here

    # --------------
    # or, use perl code
    my $proc = proc_guard(sub {
        ... # run this code in child process
    });
    ...

DESCRIPTION
Proc::Guard runs process, and destroys it when the perl script exits.

This is useful for testing code working with server process.

FUNCTIONS

proc_guard(@cmdline|\&code)
    This is shorthand for:

        Proc::Guard->new(
            command => \@cmdline,
        );

    or

        Proc::Guard->new(
            code => \&code,
        );

METHODS

my $proc = Proc::Guard->new(%args);
    Create and run a process. The process is terminated when the returned object is being DESTROYed.

    command
            Proc::Guard->new(command => '/path/to/memcached');
            # or
            Proc::Guard->new(command => ['/path/to/memcached', '-p', '11211']);

        The command line.

    code
            Proc::Guard->new(code => sub { ... });

        'code' or 'command' is required.

    auto_start
            Proc::Guard->new(auto_start => 0);

        Start child process automatically or not(default: 1).

pid Returns process id (or undef if not running).

start
    Starts process.

stop
    Stops process.

VARIABLES

$Proc::Guard::EXIT_STATUS
    The last exit status code by "$proc->stop". If "waitpid" failed with an error, this will be set to "undef".
