I specifically want to be able to use Ackmate bundle, peepcode (the new 'Go to file' seems good enough) and some other custom bundles with TM2.
I tried moving the existing bundles to a location~/Library/Application Support/TextMate/Managed/Bundles/Managed
which seem to contain all the new installed bundles, and a few other hack. But no luck yet.
I did manage to get the older themes working with TM2 though, with an approach similar to the one above.
EDIT:
I found this article on the topic.But still not able to get some older bundles to work. http://blog.macromates.com/2011/locating-bundles/
Just copy all your bundles from ~/Library/Application\ Support/TextMate/Bundles to ~/Library/Application\ Support/Avian/Bundles/
I did not find much success with the above. I guess its stil in 'Alpha'. Although you might try to drop some of the older bundles into
~/Library/Application Support/Avian/Pristine Copy/Bundles
to get it working with some hacks for now.I have managed to get Cucumber, Uber Glory and some of my custom bundles working.
Also you can follow the README of this Whitespace bundle to figure out which directory to place your new bundles in. This seems to be only bundle (not packaged) exculsively for TM2 so far.
The Textmate url that explains the difference between Avian/Pristine Copy/Bundles/ and Avian/Bundles/ is here: http://blog.macromates.com/2011/locating-bundles/
It didn't recognize my old bundles at first, but the second restart of the app worked for me.
Since this is alpha software, I think that the mailing list is the best venue for your question. Either way, I haven't yet seen anything definitive on the backward compatibility of bundle support.
