vim——编辑利器

关于vim，其实是一个永远聊不完的话题。

首先是编辑器之争，很可能又是vim和emacs之争，如果来到这里，那相比你已经认可vim了。
其实就编辑来说，我觉得用那个编辑器不是问题，重点在于用着顺手吧。
vim也是一样，有的人会说，嗯，你应该加上这个插件，有的人又说配这个插件功能很强大，关键还是自己用着顺手啊，没有任何一个配置是适合所有人的。所以说，授人以鱼不如授人以渔。

那么vim的配置方法又如何呢，可以说相当的不简单。
不同的人在不同的时间所钟情的配置方法各不相同，因为不同的人有不同的喜好，而相同的人又随着使用vim的深入，对各种功能的探索也愈盛，对vim的需求也会变化。

关于“渔”我就不多说了，后面的那个文档可以说是圣经级别的了。
而我是一名程序员，提下和程序相关的一点内容呗。

• 移动用的熟练了，hjkl绝对是王道，使用vim的vimer们恐怕没有任何一个让不认可这一点吧，我觉得这是vim最吸引我的一个特性，以至于我浏览网页及看pdf文档时都想要使用着几个按键。还好有firefox和chromium的vim插件，而debian发行版带的pdf阅读器也是支持这四个键跳转的，神奇啊。看文档时基本可以摆脱鼠标之束缚了。。。
• 跳转%在括号间跳转啊，[[及][在函数首尾跳转啊，gg及G在文件首尾跳转啊，再有m..加标记与~..跳到标记，~n打开上几次的位置啊这些，熟练运用绝对可以大大提高效率的。
• 列编辑呃，也许会用到吧，ctrl+v进入block visual模式，选择多列后使用I进入多列的插入模式，插入的字符就会自动在多列了。

• 中文编码
  与编码相关的几个变量
  1.encoding屏幕显示的编码，如使用utf-8做locale的系统，encoding就应是utf-8以方便显示。
  2.fileencodings供vi尝试的编码列表，vi会逐个尝试每一项，如果没有发生错误，就设置当前的fileencoding为与该项相同的值。如果均失败，fileencoding将为空。
  3.fileencoding正在被编辑的文件的编码，它也决定新文件的编码。如果为空，表示与encoding相同。如果与encoding不同，vi将会在保存和读取时做二者之间的转换。因此可做如下设置：

  " 设置新文件的编码为 UTF-8set fileencoding=utf8 " 自动判断编码时，依次尝试以下编码：set fileencodings=ucs-bom,gb18030,utf-8,default " gb18030 最好在 UTF-8 前面，否则其它编码的文件极可能被误识为 UTF-8

• 空白的处理
  与缩进相关的几个设置如下：

  变量名             缩写          含义(no)autoindent     ai    自动缩进，即为新行自动添加与当前行同等的缩进。(no)cindent       ci     类似C语言程序的缩进(no)smartindent    si    基于autoindent的一些改进

  与tab相关的几个设置项如下：

  变量名          缩写      含义tabstop=X        ts      编辑时一个TAB字符占多少个空格的位置。shiftwidth=X     sw      使用每层缩进的空格数。(no)expandtab    (no)et      是否将输入的TAB自动展开成空格。开启后要输入TAB，需要Ctrl-V<TAB>softtabstop=X    sts         方便在开启了et后使用退格（backspace）键，每次退格将删除X个空格(no)smarttab     (no)sta         开启时，在行首按TAB将加入sw个空格，否则加入ts个空格。

  这样只要结合自己的需要作相应的设置就可以了。* 帮助
  vim的绝大多数的设置，在你不清楚时可以使用:help xxx来获得帮助吧。

其他的如跳转啊，搜索替换啊，复制粘贴啊等等的就不多说了，反正文档里也有：
