Okay, you could do something like this:
#! /usr/bin/perl
use strict;
use warnings;
while (<>){
s/^([-a-z ]+:)(?!link|visited|hover|active)\s*(.+)/sprintf("%-20s",$1) .
"$2"/ie;
print;
}
(?!...) is a negative-lookahead assertion. It makes sure the sub-pattern
doesn't match at that point in the string, without consuming any of the
string.
However, if you can assume that a :selector will always be followed by a {
on the same line, then this might be better:
while (<>){
s/^([-a-z ]+:)\s*([^\{]+)$/sprintf("%-20s",$1) . "$2"/ie;
print;
}
