I like to see full file history regardless file renames (and with Java convention class name == file name several refactoring makes following history difficult).

This is possible in Emacs 26.1. You need to set the configuration variable vc-git-print-log-follow to t. The functionality was implemented in the following commit:

https://github.com/emacs-mirror/emacs/commit/8663fad0a70e60e130ae4cd0529ead66fbad2250

That change is a workaround for Emacs bug #8756: vc-git.el doesn't use --follow argument in vc-git-print-log but is not considered a full solution.

In the resulting *vc-change-log* buffer, not all commands are fully working. For example log-view-diff (invoked by pressing d) and log-view-annotate-version (invoked by pressing a) do not work for commits before the rename, but log-view-diff-changeset (invoked by pressing D) does work.

  • Great! This feature is marked for v26.1. I gave up with porting my `.emacs` and debugging issues with packages. So currently is at v25.3 (( – gavenkoa Feb 02 '19 at 16:00
