I have this after loading Evil at init.el top level:

Evil makes the same call if undo-tree is available on the load-path, so it's not necessary.
I'm sorry, I don't quite understand what you're trying to say. I don't have those lines in my .emacs, ...
That's exactly what Barry wanted to say, you don't need these lines because Evil executes them anyway.
My problem is that undo-tree is loaded, but disabled when I open a file with an unrecognized extension (e.g., a file named "foo", but not "foo.txt").
Again, the strange thing is that undo-tree is enabled on the *Messages* buffer, but disabled (turned off) in the "foo" buffer.
This is expected. Undo-tree (like Evil) is a minor-mode that is automatically enabled in each buffer if the corresponding "globalized minor mode" (namely global-undo-tree-mode) is enabled. This is realised by some special change-major-mode-hook and after-change-major-mode-hook hooks. However, if a new buffer is started in fundamental-mode these hooks are not run (in contrast to any other major-mode), that's why the local undo-tree-mode never gets a chance to be activated. The same is true for Evil. However, unlike undo-tree Evil adds a few additional hacks to overcome this problem. That's why Evil gets activated in fundamental-mode buffers and undo-tree does not. So if you want undo-tree to be enabled in all buffers in which Evil is enabled, the simplest solution is probably to do so directly: (add-hook 'evil-local-mode-hook 'turn-on-undo-tree-mode) Best regards, Frank
