NAME

Backtick::AutoChomp - auto-chomp() result of backtick(``) and qx//

VERSION

Version 0.02

SYNOPSIS

Automatically chomp() result of a backtick (``) or qx// command.

$s = `echo blah` . 'stuff';
print $s;   # blah\nstuff

use Backtick::AutoChomp;
$s = `echo blah` . 'stuff';
print $s;   # blahstuff
no Backtick::AutoChomp;

DESCRIPTION

In bash, the shell will automatically chomp the result of a backtick call.

s=`whoami`       # me
echo =$s=        # =me=
echo =`whoami`=  # =me=

In perl, we must** do:

$s = `whoami`;
chomp($s);
print "=$s=";

The goal of this module is for this to DWIM:

print "=".`whoami`."=";

Another case where this is potentially useful:

    use Backtick::AutoChomp;
    printf "me(%s), host(%s), kernel(%s), date(%s)\n",
	`whoami`,
	`hostname`,
	`uname -r`,
	`date`,
    ;

** Yes, there are pure-perl ways to do whoami, hostname, etc. But keep in mind programs that don't have equivalents ... and also, especially for temp/quick-n-dirty scripts, the convenience factor :)

Note that this is implemented as a source filter. It replaces a backtick or qx statement with a do{} statement.
