Backticks 1.0.9

Backticks is a Perl module that turns backticks into full objects which you can query in interesting ways.

 use Backticks;

 my $results = `ls -a /`; # Assign a Backticks object to $results

 print $results->stdout; # Get the command's STDOUT
 print $results->stderr; # Get the command's STDERR
 print $results->success; # Will be true when the command exited clean
 print $results; # Get the command's STDOUT... the object
 # stringifies to the command's output so you
 # can use it most places you use normal
 # backticks

You can have failed commands automatically die your perl script

 $Backticks::autodie = 1;
 `perl -e 'print STDERR "OUCH!\n"; exit 1'`;

Which dies with the following message:

 Error executing `perl -e 'print STDERR "OUCH!\n"; exit 1'`:
 Failed with non-zero exit code 1
 Error output:
 OUCH!

You can automatically chomp output:

 $Backticks::chomped = 1;
 my $chomped = `perl -e 'print "Hello!\n"'`;

You can even access parameters instantly in object mode by calling methods immediately after the backticks!

 say `echo foo`->stdout; # Shows 'foo'
 say `perl -e 'print STDERR "Hello world!"'`->stderr; # Shows 'Hello world'
 say `perl -e 'exit 1'`->exitcode; # Shows '1'

You can also use the classical perl object-oriented interface instead of using the backticks to create objects, the following command is the same as the first one above:

 my $results = Backticks->run("ls -la /");

Alternately, you can create a command and run it later:

 my $command = Backticks->new("ls -la /");
 # ... do some stuff
 $command->run();

Creating commands as an object affords you the opportunity to override Backticks package settings, by passing them as hash-style params:

 $Backticks::chomped = 0;
 my $chomped_out = Backticks->run(
 'echo "Hello there!"',
 'chomped' => 1,
 );
