How to compile all files in directory with Emacs

[cc lang='lisp' ]C-u 0 M-x byte-recompile-directory[/cc]

will compile all the .el files in the directory and in all subdirectories below.

The C-u 0 part is to make it not ask about every .el file that does not have a .elc counterpart.

Some commonly used Emacs commands

M-x = "meta x" = Esc, then x as described above (simultaneously codessing Alt + x, or "diamond" + x, works on some machines)
C-x = "control x" = Ctrl + x

C-shift-_ undo

M-shift-> end of buffer
M-shift-< beginning of buffer

C-a beginning of line
C-e end of line
C-k delete from cursor to end of line

M-x shell runs a shell inside emacs
M-p codevious command (in shell mode)
M-n next command (in shell mode)

C-space set mark
C-W cut all text between mark and cursor
M-W copy all text between mark and cursor
C-y paste

C-x b change buffer
C-x C-b change buffer w/list of available buffers
(move cursor over the name of the buffer
you want and hit f)

C-x 2 split the current buffer into 2, with one over the other
C-x 1 1 buffer/window
C-x 3 split the current buffer into two, with one next to the other
C-x o switch buffer

Emacs skeleton-pair Funcionality

> I have enabled skeleton-pair funcionality with what I have found in here:
> http://littlechina.org/~cmarcelo/paren-experiment.el
> It works in most modes, but in C++ mode it only works for [ and not for (,{
> or ".

Try:

(define-key c-mode-base-map (kbd "(") #'skeleton-pair-insert-maybe)
;; same for the other keys here...

or

(add-hook 'c-mode-common-hook
#'(lambda ()
(local-set-key (kbd "(") #'skeleton-pair-insert-maybe)
;; same for the other keys here...
))

If you don't like the way skeleton decides whether to insert a pair or
not but to insert a pair always use `insert-pair' instead of
`skeleton-pair-insert-maybe'.

使用Emacs作为Python开发环境

Emacs号称是编辑器之王，无所不能。可把他作为一个Python的集成开发环境

尽管Emacs那么的牛，但是从前用的多的还是简单的 vi。受不了吸引，决定开始使用Emacs进行Python的编程。

python.org上emacs的主页和对应wiki中，对python-mode竟然没有太多的介绍，反而在另外一个网站上找到了一些 emac 的资料，特别是 安装过程。

安装过程总结一下：

1. 使用最新的emacs：大于21.1的XEmacsen，或者大于20.7的Emacsen.


2. 确保安装了prog-modes这个包，在debian中很简单:
   #apt-get install prolog-el


3. 在python-mode项目中，下载python-mode.el


4. 字节编译，在emacs中输入命令（警告信息可忽略）：
   C-x C-f /path/to/python-mode.el RET
M-x byte-compile-file RET
   


5. 确保python-mode.el在加载路径中，测试方法：
   M-x locate-library RET python-mode RET
   如果没有，加入下行到自己的.emacs文件中：
   (setq load-path (cons "/dir/of/python-mode/" load-path))
   


6. 文件关联，自动将py后缀的文件和pyhton-mod关联，在自己的.emacs文件中添加：
   (setq auto-mode-alist
(cons '("\\.py$" . python-mode) auto-mode-alist))
(setq intercodeter-mode-alis
(cons '("python" . python-mode)
intercodeter-mode-alist))
   


7. 自动加载，将 python-mode 和文件 python-mode.elc关联，在自己的.emacs文件中添加：
   (autoload 'python-mode "python-mode" "Python editing mode." t)
   


8. 语法加亮，这个功能可不能少哟:) 同样在自己的.emacs文件中添加：
   ;;; add these lines if you like color-based syntax highlighting
(global-font-lock-mode t)
(setq font-lock-maximum-decoration t)
   


9. 支持中文，在.emacs中添加：
   (set-language-environment 'Chinese-GB)
(set-keyboard-coding-system 'euc-cn)
(set-clipboard-coding-system 'euc-cn)
(set-terminal-coding-system 'euc-cn)
(set-buffer-file-coding-system 'euc-cn)
(set-selection-coding-system 'euc-cn)
(modify-coding-system-alist 'process "*" 'euc-cn)
(setq default-process-coding-system
'(euc-cn . euc-cn))
(setq-default pathname-coding-system 'euc-cn)
   


好了！进入emacs试验一下：

$ emacs abc.py

可以看到emacs的底部显示：Using the CPython shell。可以试着输入一些代码，加亮显示没有问题，支持自动缩进，支持自动括号匹配提示.... 使用C-h m你可以看到python模式的详细帮助文件，功能果然很强大！
