Re: Can I use Q and E to regex match the dollar sign?

from the docs perldoc perlre:

You cannot include a literal "$" or "@" within a "\Q" sequence. An unescaped "$" or "@" interpolates the corresponding variable, while escaping will cause the literal string "\$" to be matched. You'll need to write something like "m/\Quser\E\@\Qhost/".

So, in other words, the OP would have to move the literal `$` outside the `\Q\E` set, like this: `like('asdf$',qr/\Qasdf\E\$/);` [download] The other option, of course, would be something like: `## matches a literal '[a-z]$[0-9]' using quoting like( '[a-z]$[0-9]', quotemeta('[a-z]$[0-9]') );` [download] (As ikegami pointed out above) <-radiant.matrix-> Larry Wall is Yoda: there is no `try{}` (ok, except in Perl6; way to ruin a joke, Larry! ;P) The Code that can be seen is not the true Code "In any sufficiently large group of people, most are idiots" - Kaa's Law	[reply] [d/l] [select]
