in thread Quickie Question: search and replace problem

I've created a monster! ;)

Actually, you can eventually quote them enough to get the same effect as \Q and \E. I personally like the /\Q$string\E/ construct and recommend it over the other methods I'm about to mention.

But you can also do any of these: 

$attempt= "get_stuff\\(\\)";
$attempt= "\Qget_stuff()\E";
$attempt= quotemeta( "get_stuff()" );
$attempt= qr/get_stuff\(\)/;
$attempt= 'get_stuff\(\)';

but I still find the original suggestion makes the most sense to me. In a regex (that means only the first half of s///), $x means interpret the contents of $x as a regex while \Q$x\E means interpret the contents of $x as a string.

Update: Thanks, indigo, I missed that!

    All these do the escaping properly. But the code went like this: 
    $data = $attempt;
$data =~ s/$attempt/$newstr/;

    The problem isn't simply bad escaping. Either $attempt gets munged, and the match fails, or you have to premunge $data to get $attempt right, and the match still fails.

    So /\Q$attempt\E/ really is the best way to go.
