The problem is I need $1 and $2 to put into sprintf
but I before I do that, I also need to take the '%'
operators in $2 and replace them with ',' and THEN
put it back in.
Things started to get hairy, and I was wondering
if I'm overlooking a solution that would make this
a lot easier.
the /e modifier is your friend. just put the logic to transform the $2
into the replacement section and s/// will use the value of the
expression for its replacement. if the code gets too long for the
replacement part, call out to a sub instead. for a working example with
the sub, look at Template::Simple which uses s///e to replace template
markup with recursed calls to the same sub.
