Vim tips (In fact, the use of methods, may know less than the number of people)

The following no special instructions are in command-line mode

1: Turn line numbers on and off

After pressing the Escape key to enter command mode,

: Set number command to turn on line numbers

expand: Enter command mode to &NBSP: set all   command displays a list of options and settings.

2: Turn auto indent on and off

Open: Set Autoident

OFF: Set noautoident//shorthand (: Set AI and: Set Noai)

If you enter a space or tab at the beginning of a line, subsequent new rows are indented to the same position. In command mode, enter:set  autoindent, and then press ENTER to turn on automatic indentation. By settingshiftwidthdetermines the indentation level. For example:set  shiftwidth=4set each level indent to four spaces. In command mode, you can use >> commands to add one level of indentation to an existing line, and use << commands to reduce one-level indentation. By adding an integer to these commands, you can increase or decrease the one-level indentation for multiple lines.

3: Case-sensitive problem when searching

Case-sensitive: set ignorecase

  不区分大小写 :set noignorecase//Shorthand (:set icand the:set noic )

3: Compound search

      You can use a simple regular expression to specify that the search keyword contains a word and that the word is followed by another word.


eg:想要找one关键字，在该词后面有0个或者多个更多字符，之后是字符串two的那一行。就写成 /one.*two 然后一敲回车光标就会锁定找到有该两个关键字的第一行，按下n就会找到含有这两个关键字的第二行。前提是这俩个字符串只在一行，才会匹配成功。如果不需要在一行的话，只需要把"."（点）化成";"（分号）即可。对于寻找代码中出现在另一个命令后面的某个命令非常有用，比如在设置某个变量之后调用函数的地方。
