辖vim之威学习emacs
----------------------------------------
emacs 入门还是需要看入门，指南一类的文档，自带的文档就非常好，ctrl-h 有完整的帮助。
网上也有很多快捷键，使用入门类文章。
有一定基础后，就要不断的进行实战来提高了。
借助自己已经掌握的vim技巧来迅速提高emacs技巧的笔记
1. 查询man-page
emacs: M-x manual-entry RET unix-command-name RET
vim: K
2. 执行shell 命令并读入输出到光标处
emacs: C-u M-! shell-command
vim: r !shell-command
例如我常读入shell date的输出添加到文档中
3. 重复参数
emacs: M-n or C-u n
vim: n
例如输入40个-字符
4. 自动完成输入
emacs: M-/
vim: C-f 及 C-n
5. 合并两行
emacs: M-^
vim: J
6. 插入空行
emacs: C-o C-O C-J C-e<RET>
vim: o O
7. 位置register 的使用(请正确理解意思）
emacs: C-x r SPC r --> C-x r j r
emacs 加书签: Alt-x bookmark
vim: mr --> 'r mA --> 'A
8. 简写功能:
emacs Alt-x abbrevate
vim :abbrevate
----------------------------------------
c程序员的扩展功能比较
----------------------------------------
emacs: vim 说明
M-C \ = 缩进
M-m ^ 光标移动到第一个非空字符上
M-^ J 合并两行
M-x comment-region
M-x kill comment-region
M-C-a [[ 移动到函数头
M-C-e [] 移动到函数尾
M-C-h C-v 标记函数
C-c C-u ]# 移动到上一个预处理条件
C-c C-d [# 移动到下一个预处理条件
M-; 添加注释
etags: ctags(taglist)
M-. C-]
C-x 4 . :ptags
M-x tags-search
M-x list-tags RETURN taglist插件 显示文件tag
--------------------------------------------------------------------------------
语言使用特征比较
--------------------------------------------------------------------------------
C-h v RETURN load-path :set runtimepath? emacs 的加载路径:
M-x: describing-coding-system :set file-encoding? 查看编码格式
M-x: revert-buffer-with-coding-system :e ++enc=xxxx 以指定的编码格式重新加载文件
M-x: set-buffer-file-coding-system :set file-encoding=xxx 转换缓存中的文件编码格式,这样存盘是编码就改变了.
加载其它文件
(require 'name) source name.vim
(load "name.el)
自动运行命令
(addhook 'c++-mode-hook autocmd BufRead *.cpp :call fun
'(lambda() ...))
绑定快捷键
(global-set-key cmd 'fun) nmap <silent> <F8> :call fun<CR>
(define-key c++-mode-map imap <F9> :call fun<CR>
(kbd "c-\") 'fun)

在多个文件中查找和替换.
下面只是意会,不是实际操作
把该目录下所有的cpp文件中origin 替换为 replace
emacs: 在dired 中操作
M-x find-name-dired *.cpp t Q <origin> <replace>
vim: 借助于命令行find 命令,用argdo在多个文件中查找替换.
vim `find . -name *.cpp" argdo! %s/origin/replace/
