Re: CFScript - what's the advantage?
Isn't a
cfloop from=x to =y index=i step=z
a counter loop?
Yes, it is. The difference is that the implementation is slightly less
flexible than the script version, but only slightly so, and only
noticeably so in edge cases that most of us will never see or touch or
even hear about.
x = blah;
... some other stuff ...
for (; x mod 7 neq 3; x *= sqrt(pi)) {
}
You wouldn't be able to increment x by multiplying it by the square root
of pi for example, you can only increment it by adding a signed integer
value. And similarly the to attribute is a number, rather than a
formula the way it is in a script loop, so you wouldn't be able to do
x mod 7 neq 3 as the formula for completion either, because the tag loop
is limited to checking or x number. But because most of us will
never see or touch or even hear about these kinds of cases where that
sort of thing is actually useful, the tag-loop is synonymous in well over
99% of cases. I don't know that this particular pseudocode would
actually run or work - probably not - or it would create an infinite
loop maybe - but it's really just meant to be an example. ;)

Re: CFScript - what's the advantage?
One of the reasons that Adobe have quoted is to ease migration from other languages. Attracting more developers being the goal. Personally, my eyes prefer cfscript stylee unless I'm outputting html / xml. Dominic 2009/10/5 Mike Kear afpwebwo...@gmail.com I've been trying to see what's the benefit of enhancing CFScript. There are a couple of reasons I can think of, but am I missing something? Are there more significant reasons for enhancing CFScript than I have here? Like for example performance issues? [A] I like to code using a javascript-like syntax i.e personal preference [B] if we are going to have a script-style syntax at all, it ought to be fully featured with all functions available so developers dont have to switch back and forth. [C] there are 'snobs' who think that tag-based coding isn't real coding and having a script language satisfies their need for a real programming language.

Re: CFScript - what's the advantage?
Faster to read and type when working with blocks of code. cfset var = '' vs var = ''; The other thing I like is that it enforces more of a MVC approach. Less variable declaration nested inside of your output tags and you'll find yourself writing logic outside of the HTML output. ~| Want to reach the ColdFusion community with something they want?

Re: CFScript - what's the advantage?
I would generally agree that cfscript is prettier and easier to read and we should be able to do everything in cfscript. I would more likely use it for component development where output is not typical, and the ability to build whole cfcs in cfscript is cool.

Re: CFScript - what's the advantage?
You can't express a true counter (for) loop with CFLOOP, only a condition loop (while). So that's one reason. Probably the reason I use it most often, even over reducing verbosity. Beyond verbosity and a couple edge cases, I think it's pretty much entirely personal preference. cheers, barneyb -- Barney Boisvert bboisv...@gmail.com http://www.barneyb.com/ On Oct 4, 2009, at 10:05 PM, Mike Kear afpwebwo...@gmail.com wrote: I've been trying to see what's the benefit of enhancing CFScript.
