I find that the list functions in CFML are often underutilized or
ignored by programmers, often because they come from other worlds like
ASP where 1) they traditionally had to write their own stuff to parse
strings and/or 2) they often don't pause to consider that the string
they are working on could really be considered a list in the first place.
Your city, state zip-plus4 is a plethora of lists (thank you for letting
me use that word).
First, it's a comma-delimited list. Break that apart and you then have
some space-delimited lists, Break it apart again and your zip is
potentially a hyphen-delimited list. At any point in this work, if one
of your lists has the wrong number of elements (ListLen), it's an input
validation issue. When you use CFML's listLen, listFirst, listGetAt and
listLast on all these, you don't even have to account for - or remove
those delimiters yourself (i.e. all that "length -1" stuff I'd have to
write before).
I both love your enthusiasm and agree with Matt. Sometimes you just have
to wait until you can play directly with the engine and see what
happens. I often get my best inspiration only after seeing the processed
results of my last.
