You might want to check out my JavaScript extras stuff. I have much better folding rules, for instance. (better K&R style support & comment folding) I also just added a completion pref for prototype (not yet complete).
Alright, I'll check it out, maybe we can merge our stuff into one bundle.
http://textmate.svn.subtlegradient.com/Bundles/Javascript%20Extras% 20—%20subtleGradient.tmbundle/
It's in a SVN repo, so you could just do an export of that url.
Are you expanding the JavaScript syntax, the Prototype & Scriptaculous syntax or making a new one? If yours is any good, i'll probly want to have my wrappers use yours instead.
I'm putting the prototype & scriptaculous specific stuff into one bundle (appending to the bundle from http://encytemedia.com) and more generic items to the javascript bundle).
