I've been thinking for a while that it would be nice to be able to do an interactive rebase from within TextMate.
I tried to come up with an idea of how the UI could work. One idea that comes to mind is to use the log. I imagine there would be some form of buttons (edit, squash, ...) for each commit and one "global" Start Rebase button. Ideally it should be possible to use keyboard shortcuts as well, arrow keys for selecting a commit and E, R and S for commands like edit, reword and squash.
The question now is, is it possible to use the HTML output view for something like this, or would a proper UI be required? That is create a UI in TextMate rather than in a bundle command.
The second question I have, does anyone know if it's possible to set which commits to edit, squash and so on, before starting an interactive rebase? Usually a text editor opens and the users selects the commands after starting the rebase. Perhaps using libgit2 if not through the regular command line interface.
What would also be a nice feature, or rather a shortcut of the above. Placing the cursor of a line you would like to edit, execute a command (via a keyboard shortcut) which basically does a "blame" and figures out the last commit that touched that line. Then it would start an interactive rebase and select "edit" for this particular commit.
Thoughts?
