Special Variables and Multiple Regexp Matching

[nathaniels]

Hello All,

I'm trying to create an array of regexp matches in context. What I have below clearly doesn't work as the special variables are only initialized to the first match. I've tried using a while loop but I keep getting stuck in infinite loops. What's the best way of doing this?

foreach my $line (@lines) {
    
        foreach ( lc ($line) =~ /\b $token \b/g ) {
    
            $before_string = $`;
            $after_string = $'; 
        
            if ( length $before_string > 55 ) {
                $before_string = substr( $before_string, -55 );
            }
        
            if ( length $after_string > 55 ) {
                $after_string = substr( $after_string, 0, 55 );
            }
    
            push @contexts, [$before_string, $token, $after_string];
        
        }
    }

Thanks!
