System::Sub::AutoLoad - Auto-wrap external commands as DWIM subs
version 0.130210
Any unknown sub will become a System::Sub.
System::Sub
use System::Sub::AutoLoad; my $hostname = hostname();
Allows to avoid using parentheses. System::Sub import stays lazy.
use System::Sub::AutoLoad qw(hostname); my $hostname = hostname;
Options definitions will be checked lazily at the first call to the AUTOLOAD for that sub.
use System::Sub::AutoLoad hostname => [ 0 => '/bin/hostname' ]; my $hostname = hostname;
Any unknown sub in your code will be transformed into a System::Sub at its first call. This is lazy import for System::Sub.
To avoid using parentheses after the sub name, you usually have to predeclare the sub with either a forward declaration (a sub without body such as sub foo;) or with the subs module. With Sytem::Sub::AutoLoad you can simply list the subs names on the use line and that will be done for you.
sub foo;
subs
Sytem::Sub::AutoLoad
use
You can also pass System::Sub options to the sub, but they will be lazily analysed: this is the full System::Sub power, but with lazy import.
This module exports an AUTOLOAD sub that will import the sub with System::Sub at its first call.
