Re: Regex Help - Can this be simplified?
The easiest to read solution is one line: Of course, that function will then contain a nicely spaced easy-to-read piece of logic, which almost certainly wont be a horrible single line of nested replaces. ~| Want to reach the ColdFusion community with something they want?

RE: Regex Help - Can this be simplified?
You don't actually need a regex to put this into one easily read line:
replaceList(trim(finalDesription), ',,,', ',,,')
... Or some derivative there of.
Performance may differ slightly in favour of one way or another, but as much
as I love regexs and I use them frequently, they're rarely easy to descipher
at a glance.

You're better off using regex-replace(){rereplace()} over replace() for more
than one condition. The pipe is a way to cheat the replace function but for
future string searching or replacing functions, try regex and you can even
test it online here:

Sorry I didn't read the post very well rereplace(form.description,"()+()+()","","all") This does not replace a single with but I think it does the job. ~| Want to reach the ColdFusion community with something they want?

Re: Regex Help - Can this be simplified?
Easy there, killer. You said "A". I said "B". You didn't preface it with "in my opinion" any more than I did. I still maintain that (in my opinion), it's preferable to write more legible code. The single line may be just as easily readable for you, but you may not always be the one maintaining your code.

RE: Regex Help - Can this be simplified?
This, of course, is completely a matter of opinion. I prefer 1 line - faster processing, and still easy to support. Again, that's MY opinion, and I'm sure we have about a hundred other opinions on this list. There's no doubt that there are many ways to accomplish something in ColdFusion. But an alternate method should not be shot down as "not simplified" especially when the provider of the alternate method was just trying to help.

RE: Regex Help - Can this be simplified?
Charlie, think of my problem like this. Say you had any 5 character combos you wanted to remove, for whatever reason. I'm just looking for a simpler (or so I thought) RegEx way to do this. I could loop over a list, but I thought (perhaps naively) there might be a Regex function that could accepta a list of chars and then replace any of them when a match was found. -Original Message- From: Charlie Griefer [mailto:charlie.grie...@gmail.com] Sent: Thursday, August 13, 2009 2:29 PM To: cf-talk Subject: Re: Regex Help - Can this be simplified? less lines != simplified :) A year from now, which version are you going to want to come back to when it needs work?
