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][1] 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!
