in reply to how to overcome Win32 path delimiter in s///?

Wrap $path in \Q and \E (which escapes metachars) like so...

my $file = 'c:\some\win32\path\mydir\file.txt'; my $path = 'c:\some\win32\path'; (my $file_nopath_noext = $file) =~ s/\Q$path\E\\(.*)\.txt/$1/; print $file_nopath_noext."\n";

    that's precisely what I was hoping for. I failed to consider \Q..\E metacharacter manipulation. Thank you
      The function quotemeta will acomplish the same thing if you use it on the value before it is interpolated by the regex.

      If you are particularly worried about forward slashes then you can just use an alternate character to delimit the parts of the substitution.
      e.g. single char s!!! or paired s()()
