Re: \Q \E misunderstanding

[Glenn Linderman]

On approximately 9/24/2004 11:53 PM, came the following characters from 
the keyboard of Glenn Linderman:

I have the following code:
      my $ftype;
      { my $assoc = `assoc .html`;
        $assoc =~ [EMAIL PROTECTED]@@;
        print "assoc: $assoc\n";
        $ftype = `ftype $assoc`;
        $ftype =~ [EMAIL PROTECTED]@@;  ## this line is referred to below
        print "ftype: $ftype\n";
      }
Because I don't know what the content of $assoc is going to be, i.e. 
whether it will contain any characters that are regular expression 
meta-characters, I seem to want to apply \Q \E around the $alloc= string 
in the line marked above.  But if I do, it appears that the $assoc is 
not interpolated.  So I don't.  But then what happens if $assoc contains 
RE meta-characters?

Is this a paradox, or is there a solution?
Sorry, it is too late at night.  I convinced myself that
  $ftype =~ [EMAIL PROTECTED]@@;
was the problem, but it must have been something else... and now I've 
figured out the something else... I need to chomp $assoc and $ftype at 
appropriate points.

Sorry for disturbing your sleep, but having resolved this one is going 
to make me sleep better!
