identPython.pl

#this little script will put the right identation for python script if was ill-formated (due to pasting code to web page, say)
#perl identPython.pl < ill_formated_python_code > good_python_code

$level = 0;
while (<STDIN>) {
	chomp($line = $_);
	$line =~ s/^\s*//;
	if ($line eq "") {
		$level = 0;
		print "\n";
	} else {
		if ($line =~ /^else:/) {
			$level --;
		}
		print "\t"x$level;
		print $line,"\n";
		if ($line =~ /\:$/) { $level ++; }
	}
}

I did this not realizing there is such a tool written in python already! Needed this to run a python script copied from pdf file.
