Hi Luca,

use the /e modifier to evaluate the right-hand side of the RE.

$b =~ s/\:\:/File::Spec->rootdir()/e ;

Enjoy,
Mickey

    The /e is the best option, I think.
    But just to mention it, there is another way to do it:
    $b =~ s/\:\:/${\(File::Spec->rootdir())}/;
    The trick is to use de-reference a refence to a value. You can put almost any expresion inside the ${\( )} and it will be well evaluated.
