EmacsEldoc 全局化了
======
![](https://img.linux.net.cn/data/attachment/album/201909/05/045702d99v9vv4xy0aybmm.jpg)
最近我注意到 Emacs 25.1 增加了一个名为 `global-eldoc-mode` 的模式,它是流行的 `eldoc-mode` 的一个全局化的变体。而且与 `eldoc-mode` 不同的是,`global-eldoc-mode` 默认是开启的!
这意味着你可以删除 Emacs 配置中为主模式开启 `eldoc-mode` 的代码了:
```
;; 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)
```
[有人说][1] `global-eldoc-mode` 在某些不支持的模式中会有性能问题。我自己从未遇到过,但若你像禁用它则只需要这样:
```
(global-eldoc-mode -1)
```
现在是时候清理我的配置了!删除代码就是这么爽!
