I watched as another nightly build of TextMate 2 was installed on my machine and then looked over the Release Notes to find the following:
TextMate is now built with
libc++
and as a 64 bit application using the new Objective-C run-time. Ideally no changes affecting the user, but a lot has changed under the hood. (Jacob Bandes-Storch)
Awesome. Sauce. Seems that opening up the source to the community is paying dividends so far. Right now there is a pretty lengthy discussion about split-pane views and what that might mean for TextMate 2.
I am enjoying watching all of the development going on right now.
