Hi folks, Thanks for pointing that out Hugo. I'm currently trying to extend it so that for the line 
/*  sdfthrow OtherException

[download]
prints 'Opening extended comment' but does not for the line 
throw new Exception() /* asdfasdf

[download]
Basically so long as the '/*' hasn't been preceeded with a throw then it should print out opening the comment. I've got the following expression in place. 
if ($line =~ /^.*\/\*((?:(?<!throw)).*$/ )
{
        debug("Opening extended comment");
}

[download]
Is my understanding this expression correct? Would folks mind if I explain what I think is going on from left-right?

/^ matches the start of the $line string

.* says that the start can be proceeded by any number of characters

\/\* matches the '/*' string

(?:(?<!throw)) means so long as /* isn't preceeded in the string by the word throw $line still matches

.*$ means that any number of characters can proceed the /* upto the end of the line

My understanding's obviously incorrect cos eh.. it don't work for a lad. Any help would be greatly appreciated, Mark.
