NAME

IOMux::Open - simulate the open() function

SYNOPSIS

            

              
              
use IOMux::Open qw( -| |- |-| < > >> tcp);
# pipe for reading
my $who = $mux->open('-|', 'who', 'am', 'i');
print <$who>;
# two-way connection (like IPC::Open3)
my $echo = $mux->open('=|', 'cat');
# file
my $pw = $mux->open('<', '/etc/passwd');
my @noshell = grep /\:$/, <$pw>;
            
          

DESCRIPTION

This module is a simple wrapper to bring various alternative connection implementations closer to normal Perl. It also saves you a lot of explicit require (use) lines of code.

With this module, code is simplified. For instance, the real logic is:

            

              
              
use IOMux::Pipe::Read;
my $who = IOMux::Pipe::Read->new
 ( run_shell => [ 'who', 'am', 'i' ]
 );
$mux->add($who);
print <$who>;
            
          

In the short syntax provided with this module:

            

              
              
use IOMux::Open '-|';
my $who = $mux->open('-|', 'who', 'am', 'i');
print <$who>;
            
          

You only need to use one ::Open module with some parameter, in stead of requiring all long names explicitly. As you can see, the object gets added to the mux as well.
