I just submitted the idea below as a pull request [1] to the GSoC ideas page, but I'd like to get some mailing list feedback first that the idea is sensible...
And, is there anybody else willing to volunteer as a mentor for this project? (There should be at least two.) Michael [1] https://github.com/git/git.github.io/pull/5 ## Line options for `git rebase --interactive` One of the more powerful features in Git is the command `git rebase --interactive`, which allows recent commits to be reordered, squashed together, or even revised completely. The command creates a todo list and opens it in an editor. The original todo list might look like: pick deadbee Implement feature XXX pick c0ffeee The oneline of the next commit pick 01a01a0 This change is questionable pick f1a5c00 Fix to feature XXX pick deadbab The oneline of the commit after The user can edit the list to make changes to the history, for example to pick deadbee Implement feature XXX squash f1a5c00 Fix to feature XXX exec make edit c0ffeee The oneline of the next commit pick deadbab The oneline of the commit after This would cause commits `deadbee` and `f1a5c00` to be squashed together into one commit followed by running `make` to test-compile the results, delete commit `01a01a0` altogether, and stop after committing commit `c0ffeee` to allow the user to make changes. It would be nice to support more flexibility in the todo-list commands by allowing the commands to take options. Maybe * Convert a commit into a merge commit: pick -p c0ffeee -p e1ee712 deadbab The oneline of the commit after * After squashing two commits, add a "Signed-off-by" line to the commit log message: pick deadbee Implement feature XXX squash --signoff f1a5c00 Fix to feature XXX or GPG-sign a commit: pick --gpg-sign=<keyid> deadbee Implement feature XXX * Reset the author of the commit to the current user or a specified user: pick --reset-author deadbee Implement feature XXX pick --author="A U Thor <aut...@example.com>" deadbab The oneline of the commit after The goal of this project would be (1) to add the infrastructure for handling options on todo-list lines, and (2) implement some concrete options. A big part of the difficulty of this project is that `git rebase --interactive` is implemented via a sparsely-commented shell script. Adding comments and cleaning up the script as you go would be very welcome. - Language: sh - Difficulty: medium - Possible mentors: Michael Haggerty -- Michael Haggerty mhag...@alum.mit.edu http://softwareswirl.blogspot.com/ -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
