Has anyone found a better fix than downgrading format.rb? A little reluctant to do so...
Unfortunately, no. I've e-mailed the bundle author twice but assume he is busy with other work at the present time. I'm assuming that GTDAlt along with other bundles that have issues with Leopard's Ruby will be making some changes once TextMate v2 is released, as it will require Leopard.
I, for one, am looking forward to both an updated GTDAlt and a shiny new TextMate.
Kind regards, Mark
