[Emacs] Play With Emacs(一)

emacs循序渐进

基本设置如下 emacs setting

org mode除了可以写备忘录，TODO,还可以做其他的
- org文件来管理emacs的配置
- org文件可以用reveal.js做成ppt
- org文件可以直接eval出来结果并显示出来
- pandoc可以在不同文件格式转换，包括org
```
(use-package org-bullets
    :ensure t
    :config
    (add-hook 'org-mode-hook (lambda () (org-bullets-mode 1))))
```

Ace window

不同子窗口切换的时候，会有个窗口编号，方便切换

(use-package ace-window
    :ensure t
    :config
    (setq aw-scope 'frame) ;; was global
    (global-set-key (kbd "C-x O") 'other-frame)
    (global-set-key [remap other-window] 'ace-window))

Swiper

方便导航和搜索

(use-package counsel
    :ensure t
    )

    (use-package swiper
    :ensure try
    :config
    (progn
    (ivy-mode 1)
    (setq ivy-use-virtual-buffers t)
    (global-set-key "\C-s" 'swiper)
    (global-set-key (kbd "C-c C-r") 'ivy-resume)
    (global-set-key (kbd "<f6>") 'ivy-resume)
    (global-set-key (kbd "M-x") 'counsel-M-x)
    (global-set-key (kbd "C-x C-f") 'counsel-find-file)
    (global-set-key (kbd "<f1> f") 'counsel-describe-function)
    (global-set-key (kbd "<f1> v") 'counsel-describe-variable)
    (global-set-key (kbd "<f1> l") 'counsel-load-library)
    (global-set-key (kbd "<f2> i") 'counsel-info-lookup-symbol)
    (global-set-key (kbd "<f2> u") 'counsel-unicode-char)
    (global-set-key (kbd "C-c g") 'counsel-git)
    (global-set-key (kbd "C-c j") 'counsel-git-grep)
    (global-set-key (kbd "C-c k") 'counsel-ag)
    (global-set-key (kbd "C-x l") 'counsel-locate)
    (global-set-key (kbd "C-S-o") 'counsel-rhythmbox)
    (define-key read-expression-map (kbd "C-r") 'counsel-expression-history)
    ))
