in thread qr// and user provided regex patterns...

I suspect that qr was not intended to be used on an entire subsitution operator like that. I believe it should only be used on the regular expression portion (left side) of the subsitution. See perlop.

Here is an example script which uses s/// as a command-line option:

    so I pretty much will have to split it and evaluate it like this: eval("$text =~ s/$pa/$tx/$md"); It might be difficult splitting a regex that could contain multiple /'s. I'll have to adjust the program so the user enters the pattern, and replacement separately I guess.

[1nickt]: There is "Don;t show embedded d/l links" in Display settings. It is unchecked.
[1nickt]: Oh, there is a minimum lines setting!
