RE: Which code reuse method?
I think components still make the most reusable choice for things like this. I throw all my utility type functions into one cfc and call the correct function according to what is required, even if no input is required it still has the desired affect of doing xyz. These don't change often so I normally put them in the application scope Then just call the required function when needed. Hi visitor, the phrase of the day is #application.utilities.phraseOfDay()# That might make sense for some things, but if you don't have enough of these items to justify a cfc then it's overkill. Also, what if it is something that isn't used everywhere or very often? Then you have the code taking up space in memory that is rarely used. CFCs and custom tags both have their place. I believe that in this case the custom tag is the better bet. There are also other advantages to custom tags. When our group creates a custom tag for our use, generally one of us also generates the changes for cfeclipse/homesite 5.5+/etc so those custom tags are actually recognized by the ide and can provide help/tag insight. Not so easy with a cfc (as far as I know, I could be wrong).

RE: Which code reuse method?
Shannon, In some ways you are right, but for code reuse I still believe the custom tag is the way to go. Say you put the code in /webroot/myIncludes/myReusableCode.cfm. Someone working in /webroot/Application1/SubApp1/report would have to use either or if the /webroot is mapped correctly. Using the custom tag method you can put in and it works even if you move the cfm files that reference that tag. If you use the ../.. method however when you move files around, each file would then have to be edited. The mapping method would still work. Another advantage of using this method is if they needed to override your custom tag with one similar all they have to do is create a file of the same name in the current directory. Also, it's not hard at all to add a directory to use as custom tags. You make the directory and tell them to add it to the list of directories to search. For the administrators, that's just a few characters typed into a field in the CF Administrator. Very simple.

RE: Which code reuse method?
The two I would look at and use as it makes sense would be either to create it as a custom tag someplace everyone can get to it (cfmodule calls work too here) or make it as an application scoped udf that gets included onapplicationstart. We have a ton of udfs that are included once and used al over the place. A cfc does seem to be going overboard to me. I like the UDF Idea personally. -Original Message- From: Shannon Rhodes [mailto:shan...@rhodesedge.com] Sent: Tuesday, May 11, 2010 10:56 AM To: cf-talk Subject: Which code reuse method?

If your custom tag doesn't surround anything, make sure you add this line: That way if you have programmers that self close tags (), it won't run twice.

Re: Which code reuse method?
We set a variable in our onApplicationStart() method that looks at the server and defines an Application level variable for the server environment (which we'll move to the Server scope once we transition to CF9).
