Emacs 使用YASnippet

1 安装YASnippent

$ cd ~/.emacs.d/plugins$ git clone https://github.com/capitaomorte/yasnippet

Add the following in your .emacs file:

(add-to-list 'load-path              "~/.emacs.d/plugins/yasnippet")(require 'yasnippet)(yas/global-mode 1)

2 安装 org-mode字典

# git clone git://github.com/rvf0068/yasnippets.git## 复制yasnippets/org-mode目录到yasnippet/snippets/目录下# cp -r yasnippets/org-mode /root/.emacs.d/site-lisp/yasnippet/snippets/

3 org-mode中使用教程

Snippets for org-mode. See .

They have bindings C-c y plus an extra letter.

I have added a condition statement so that the snippets can be expanded only at the beginning of the line.

name	key	letter	explanation
#+begin_ …#+end_	block	b
#+srcname:..#+begin_src…#+end_src	sb	s	source block with name
attr_html	ath		alt="$1" img class="aligncenter"
attr_latex	atl		${1:width=$2\textwidth}
author	aut	a	inserts `#+author:`
corollary	cor	c	(uses reftex)
definition	def	d	(uses reftex)
ditaa	dit		#+begin_ditaa,+end_ditaa
el	el		#+begin_src emacs-lisp,+end_src
email	email		inserts `#+email:`
equation	eqn	e	(uses reftex)
figure	fig	f	asks for image file
language	lan		inserts `#+language:` (with choice)
LaTeX class	lcl		inserts `#+latex_class:` (with choice)
LaTeX header	lhe		inserts `#+latex_header:`
lemma	lem	l	(uses reftex)
options	opt	o	inserts `#+options:`
proof	prf
properties folded	properties		inserts visibility folded property
proposition	pro	p	(uses reftex)
startup	sta		inserts `#+startup:`
text	text		inserts `#+text:`
theorem	thm	t	(uses reftex)
tikz-picture	tkz	z	(uses reftex)
title	title		inserts `#+title:`

4 YASnippet增加模板

这么强大的工具要是没有定制功能简直太可惜了.不过我找了很久也没有找到.以为直接编辑文件就可以的,但是结果还是不成功.

还得一步一个脚印的来.幸好有元旦的5天假期,否则不知道我会不会因为没有耐心而放弃研究它了呢.

下面举个例子增加 cnblogs的bash着色模块.

ESC x yas/new-snippet 来进入新建snippet的buffer,可以看到以下的内容:
```
　# -*- mode: snippet -*- 　# name:  　# key:  　# binding: direct-keybinding 　# expand-env: ((some-var some-value)) 　# type: command 　# --
```
其中:
- name: 是在YASnippet中显示的名字.
- key: 是触发这个snippet所用的关键字.
- binding 和　expand-env, type 是一些高级特征,这里不做研究.

将上面的内容改为(不需要的行删掉):
```
# -*- mode: snippet -*-   # name: src_bash   # key: bash   # --   #+BEGIN_HTML  
            
             ${1:#!/bin/bash}  $0  
  
          
   #+END_HTML
```
其中: ${N: Some Text} 的内容被称为字段, N 是tab stop序号(顺序是从$1-$N的),冒号后面的文本则是默认值.最近 $0 被称为YASnippet的退出点,即一个key被展开为snippet,并按顺序走完所有的tab stop之后光标停留的点.
