安装 & 使用
sudo apt-get install emacs
$ git clone https://github.com/syl20bnr/spacemacs ~/.emacs.d

git clone https://github.com/syl20bnr/spacemacs.git ~/.emacs.d -b develop
git clone https://github.com/zilongshanren/spacemacs-private.git ~/.spacemacs.d/
如果使用了 .spacemacs.d 目录来保存你的 spacemacs 配置,就不需要在 HOME 目录维护一个 .spacemacs 文件了。 至于为什么要使用 .spacemacs.d 目录而不是 .spacemacs 文件,主要是方便分离自己的配置与 spacemacs 的配置,更新更容易。
如果发现添加在 .spacemacs.d/init.el 里面的配置没有生效,检查一下是否你的 HOME 目录还存在一个 .spacemacs 文件。

问题汇总

File error: Cannot open load file, No such file or directory, bind-map
解決方法:
bind-map spacemacs启动的时候下载的 选择 spacemacs-base 模式先把bind-map下载下来

ELPA 镜像http://elpa.emacs-china.org

添加下面的代码到.spacemacsdotspacemacs/user-init()
(setq configuration-layer--elpa-archives

'(("melpa-cn" . "http://elpa.emacs-china.org/melpa/")
  ("org-cn"   . "http://elpa.emacs-china.org/org/")
  ("gnu-cn"   . "http://elpa.emacs-china.org/gnu/")))

使用代理

(setq url-proxy-services
   '(("no_proxy" . "^\\(localhost\\|10.*\\)")
     ("http" . "127.0.0.1:8087")
     ("https" . "127.0.0.1:8087")))

emacs 中怎么删除最大匹配的括号中的内容?

先把光标放置到最左边的括号处,然后C-M-K就可以

跳转总结:
同一层级
( 往前跳|往上跳 C-M-b backward-sexp

往前跳|往上跳 C-M-p backward-list

上一级
( 往上跳 C-M-u backward-up-list

##
优化删除括号的函数

这一期没啥内容,只是最近写代码的时候发现 Emacs 自带的删除括号功能 ('delete-pair)非常的原始且不好用,于是随手写了个优化的版本。
(defun c-delete-pair ()
(interactive)
(let ((re "[([{<'\"]"))

(when (or (looking-at-p re) (re-search-backward re nil t))
  (save-excursion (forward-sexp) (delete-char -1))
  (delete-char 1))))

使用该函数可以向前搜索括号(以及引号)然后删除匹配的括号(或者引号)。

** Use-package

  • Always use =progn= when a code block requires multiple lines for =:init= or
    =:config= keywords.
  • If there is only one line of code then try to keep =:init= or =:config=
    keywords on the same line.
  • Don't nest multiple =use-package= calls unless you have a very good reason
    to do it.

Emacs 服务器

Spacemacs 会在启动时启动服务器,这个服务器会在 Spacemacs 关闭的时候被杀掉。

使用 Emacs 服务器

当 Emacs 服务器启动的时候,我们可以在命令行中使用 emacsclient 命令:

$ emacsclient -c 用 Emacs GUI 来打开文件

$ emacsclient -t 用命令行中 Emacs 来打开文件

杀掉 Emacs 服务器

除了关闭 Spacemacs 之外,我们还可以用下面的命令来杀掉 Emacs 服务器:

$ emacsclient -e '(kill-emacs)'

持久化 Emacs 服务器

我们可以持久化 Emacs 服务器,在 Emacs 关闭的时候,服务器不被杀掉。只要设置 ~/.spacemacs 中 dotspacemacs-persistent-server 为 t 即可。

但这种情况下,我们只可以通过以下方式来杀掉服务器了:

SPC q q 退出 Emacs 并杀掉服务器,会对已修改的 Buffer 给出保存的提示。

SPC q Q 同上,但会丢失所有未保存的修改。

问题整理

deft 模式增加 q 退出
; (evil-define-key 'normal deft-mode-map "q" 'quit-window)
(with-eval-after-load 'deft
(bind-map-set-keys deft-mode-map "" 'deft-new-file)
(define-key deft-mode-map (kbd "C-g") 'quit-window)
)

设置启动模式

(evil-set-initial-state 'magit-status-mode 'emacs)

magit自动进入插入模式

  1. Default to insert state in COMMIT_EDITMSG buffers ?

    (add-to-list 'evil-buffer-regexps
                     '("COMMIT_EDITMSG" . insert))
    
    (push '("*magit" . emacs) evil-buffer-regexps)
    (push '("\\`CAPTURE-" . insert) evil-buffer-regexps)
    (add-hook 'org-capture-mode-hook 'evil-insert-state)
    

** Disable evilification of a mode?

You can ensure a mode opens in emacs state by using =evil-set-initial-state=.

#+BEGIN_SRC emacs-lisp
(evil-set-initial-state 'magit-status-mode 'emacs)
#+END_SRC

You can also do this using buffer name regular expressions. E.g. for magit,
which has a number of different major modes, you can catch them all with

#+BEGIN_SRC emacs-lisp
(push '("*magit" . emacs) evil-buffer-regexps)
#+END_SRC

This should make all original magit bindings work in the major modes in
question. To enable the leader key in this case, you may have to define a
binding in the mode's map, e.g. for =magit-status-mode=,

#+BEGIN_SRC emacs-lisp
(with-eval-after-load 'magit
  (define-key magit-status-mode-map
    (kbd dotspacemacs-leader-key) spacemacs-default-map))
#+END_SRC

** Include underscores in word motions? 单词移动包含下划线_

You can modify the syntax table of the mode in question. To do so you can
include this on your =dotspacemacs/user-config=.

#+BEGINSRC emacs-lisp
;; For python
(add-hook 'python-mode-hook #'(lambda () (modify-syntax-entry ?
"w")))
;; For ruby
(add-hook 'ruby-mode-hook #'(lambda () (modify-syntax-entry ?_ "w")))
;; For Javascript
(add-hook 'js2-mode-hook #'(lambda () (modify-syntax-entry ?_ "w")))
#+END_SRC

  1. 常见的 Emacs 的快捷键设置主要有四种类型
    那就从妖艳酷炫的快捷键开始吧!(一) - Ghost in Emacs - 知乎专栏
    全局快捷键:
    (global-set-key (kbd "A") 'your-command)
    (global-unset-key (kbd "grm"))
    等价于
    (define-key global-map )
    全局映射键:
    (define-key key-translation-map (kbd "A") (kbd "B"))

基于 Major-Mode 的局部快捷键,以及
(local-set-key (kbd "A") 'your-command)
(local-unset- ("laptop" . ?l) ("pc" . ?p)))

定义需用到的快捷键
a-z 直接插入已定义的 TAGS
切换到手动输入 TAGS
清空所有 TAGS
! 关闭或开启互不相容的 TAGS 标记
q/C-g 退出设置key (kbd "grm"))

基于 Minor-Mode 的局部快捷键,对应的命令分别是
(define-key your-minor-mode-map (kbd "A") 'your-command)
(define-key evil-normal-state-map "q" 'evil-force-normal-state )
(define-key evil-normal-state-map "q" nil )

(define-key global-map (kbd "C-c t") 'org-capture)

* Binding keys

Key sequences are bound to commands in Emacs in various keymaps. The most basic
map is the =global-map=. Setting a key binding in the =global-map= is achieved
with the function =global-set-key=. Example to bind a key to the command
=forward-char=:

#+BEGIN_SRC emacs-lisp
(global-set-key (kbd "C-]") 'forward-char)
#+END_SRC

The =kbd= macro accepts a string describing a key sequence. The =global-map= is
often shadowed by other maps. For example, =evil-mode= defines keymaps that
target states (or modes in vim terminology). Here is an example that creates the
same binding as above but only in =insert state= (=define-key= is a built-in
function. =Evil-mode= has its own functions for defining keys).

#+BEGIN_SRC emacs-lisp
(define-key evil-insert-state-map (kbd "C-]") 'forward-char)
#+END_SRC

Perhaps most importantly for Spacemacs is the use of the bind-map package to
bind keys behind a leader key.
This is where most of the Spacemacs bindings live. Binding keys behind the
leader key is achieved with the functions =spacemacs/set-leader-keys= and
=spacemacs/set-leader-keys-for-major-mode=, example:

#+BEGIN_SRC emacs-lisp
(spacemacs/set-leader-keys "C-]" 'forward-char)
(spacemacs/set-leader-keys-for-major-mode 'emacs-lisp-mode "C-]" 'forward-char)
#+END_SRC

These functions use a macro like =kbd= to translate the key sequences for you.
The second function, =spacemacs/set-leader-keys-for-major-mode=, binds the key
only in the specified mode. The second key binding is active only when the
major mode is =emacs-lisp=.

Finally, one should be aware of prefix keys. Essentially, all keymaps can be
nested. Nested keymaps are used extensively in spacemacs, and in vanilla Emacs
for that matter. For example, ~SPC a~ points to key bindings for "applications",
like ~SPC a c~ for =calc-dispatch=. Nesting bindings is easy.

#+BEGIN_SRC emacs-lisp
(spacemacs/declare-prefix "]" "bracket-prefix")
(spacemacs/set-leader-keys "]]" 'double-bracket-command)
#+END_SRC

The first line declares ~SPC ]~ to be a prefix and the second binds the key
sequence ~SPC ]]~ to the corresponding command. The first line is actually
unnecessary to create the prefix, but it will give your new prefix a name that
key-discovery tools can use (e.g., which-key).

There is much more to say about bindings keys, but these are the basics. Keys
can be bound in your =~/.spacemacs= file or in individual layers.
