In order to keep this stuff updated better and available for others to use, and hopefully help improve, I’ve created a Google Code project named Core SWF.

Right now this doesn’t have a whole ton of stuff, but it does have:

• Updated ActionScript and MXML language spec files (Including AS in MXML script blocks)
• A basic ActionScript 3 project template (Integrated with the Flex 3 SDK Ant tasks)

Gradually I’ll be adding more advanced project templates.

This is all updated to work with Xcode 3.1 as well.

You can download the very first 0.1 release on the project site.

Ping me for SVN access if you want to help add or improve some stuff. enefekt at that Google email service.

Xcode 3 switched from pblangspec files to xclangspec. The macros format and pbfilespec files had a few tweaks to be made as well. There are a few lines still left in the pblangspec file, Xcode didn’t seem happy without them, or with them moved into the xclangspec file. I wasn’t able to keep the method parameters in the code completion, it wouldn’t properly work with some of the different characters in there. I tried a few things, but it didn’t work. If I or someone else gets that figured out, it will be updated.

As a brand spankin’ new addition, and as a result of Xcode 3 having better support for XML, I was able to get an xclangspec going for MXML too! I even have ActionScript in the CDATA blocks working! It works hand-in-hand with the ActionScript.xclangspec file.

This is a first stab, and no doubt can be improved on, but at least I’m rockin’ and rollin’ with Xcode 3 now. To use, just drop the files here:
/Developer/Library/Xcode/Specifications/

If you are moving a project over from an older Xcode project, the ActionScript and MXML files may not automatically register. As you work on them, simply do a “Get Info” (Command+I), and select either “sourcecode.actionscript” or “sourcecode.mxml” for the type in the inspector.

Here you go, enjoy!
