Eldoc Goes Global
I recently noticed that Emacs 25.1 had added a global variant of the popular eldoc-mode, called global-eldoc-mode. What’s more - unlike eldoc-mode, global-eldoc-mode is enabled by default!
This means that you can get rid of all the code in your Emacs config that was wiring up eldoc-mode for major modes that support it:
;; That code is now redundant
(add-hook 'emacs-lisp-mode-hook #'eldoc-mode)
(add-hook 'ielm-mode-hook #'eldoc-mode)
(add-hook 'cider-mode-hook #'eldoc-mode)
(add-hook 'cider-repl-mode-hook #'eldoc-mode)
There are some reports that global-eldoc-mode is causing performance issues in modes that don’t support it. I’ve never experienced this myself, but if you want to disable it you can simply do so like this:
(global-eldoc-mode -1)
Now it’s time to clean up my config! Deleting code always feels so good!
