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.

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.

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

The command line.

code

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

'code' or 'command' is required.
