Automate the removal of git-rebase-mode and git-commit-mode

Question

From the Magit docs:

Furthermore the old dependencies git-commit-mode and git-rebase-mode have to be removed because they are no longer used by the 2.1.0 release and later, and get in the way of their successors git-commit and git-rebase.

I have a lot of machines that have these old packages lying around. Is there any way I can teach magit to automatically clean them up?

Answer 1

This should be your package manager's duty, not magit, if you are using package.el on Emacs 25, you can try package-autoremove. From C-h f package-autoremove:

(package-autoremove)

Remove packages that are no more needed.

Packages that are no more needed by other packages in ‘package-selected-packages’ and their dependencies will be deleted.

There is a post from Artur Malabarba on this: http://endlessparentheses.com/new-in-package-el-in-emacs-25-1-better-dependency-management.html

Answer 2

https://stackoverflow.com/questions/20541322/how-to-remove-installed-elpa-package suggests simply removing the package directories from your disk.

package-delete is undocumented in Emacs 24, but seems to do the same thing (as well as removing any .signed file corresponding to the deleted package).
