IOMux::Open - simulate the open() function
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>;
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
::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.
- IOMux::Open->new($mode, $params)
Available MODES are
-| IOMux::Pipe::Read |- IOMux::Pipe::Write |-| IOMux::IPC |=| IOMux::IPC (with errors) > IOMux::File::Write >> IOMux::File::Write (appendinf) < IOMux::File::Read
