I have had a few people ask me if I am going to update CFQuickDocs to include ColdFusion 9 tags and function documentation. The quick answer is...it depends. ;)
It will all depend on the pricing for Adobe CFBuilder. Unless I've missed it, Adobe hasn't announced whether or not CFBuilder will be free. If it is free, I will probably not update CFQuickDocs. Why? Because I think CFBuilder has awesome built-in tag/function documentation. You can put your cursor on any tag or function and then hit F1, and it will quickly bring up documentation for that tag/function. In my opinion, this makes CFQuickDocs redundant.
That said, I realize that not all CF developers like and will use CFBuilder (there seems to be a lot of hatred for Eclipse out there, for some reason). Personally I love Eclipse. But I understand that a lot of people think it's bloated and slow. However, I challenge you to find a full fledged IDE on par with Eclipse and Visual Studio that doesn't seem a bit bloated and slow. There is a LOT going on under those covers! :)
Back to the main subject...if I do decide not to update CFQuickDocs, I will be asking for community help. If there is some kind soul out there that would be willing to put the man hours into creating the database records for CF9 docs, I'd be more than happy to work with them on updating CFQuickDocs. I will always leave cfquickdocs.com up and running as long as people keep using it.
