RE: CFINCLUDES and RE: CFC Performance Best Practice
Ok Sean, on the performance I read that somewhere but cannot recall where, when I do I will point it out. With regard to coding bad practice I have no doubts that multiple layers of nested includes-custom tags are bad practice as they make code very hard to read and follow. Our opinion here at Webapper is that all who see our code should be able to fully understand what we did, how and why and even with the best of commenting multi-level nested includes are very hard to follow.

RE: CFINCLUDES and RE: CFC Performance Best Practice
Actually I disagree with this. It is true that breaking up code into smaller blocks that are contained in several files can make code hard to follow. Sometime you go from template - includes - tags - storedprocs - to database - triggers.. which can be pretty confusing. However the benefit of this approch becomes evident when you start changing code. And good documentation will help you here... Of course there is a difference between good abstraction and just writting spaghetti code, and I've written both:-) WG -Original Message- From: Mike Brunt [mailto:[EMAIL PROTECTED] Sent: 24 March 2003 18:01 To: CF-Talk Subject: RE: CFINCLUDES and RE: CFC Performance Best Practice Ok Sean, on the performance I read that somewhere but cannot recall where, when I do I will point it out.

Hmm, it isn't the multiple layers that make code hard to read per se so it must something else. It is generally accepted best practice in software engineering to break code down into smaller, reusable chunks. In CF, that has historically translated into includes and custom tags (and now it's UDFs, custom tags and CFCs). If this is done properly, it should be very readable and easy to maintain. That means using good, clear naming and an 'obvious' decomposition into smaller parts. If you choose a bad decomposition then of course you get unreadable code!
