Second, vi option settings

VI is a powerful editor, it can not only be used to deal with our usual text work, but also can be used to write program files. When using VI for program editing, it can achieve syntax highlighting, automatic indentation, bracket matching and other editing functions. To control different editing functions, VI offers many internal options.

Use the: Set command to set options. The basic syntax is:
: Set option Settings options
Common feature options include the following:
Autoindent Set this option, the body is automatically indented
ignorecase Set this option, the difference between uppercase and lowercase letters in the rule expression is ignored
Number sets this option to display the body line numbers
Ruler Set this option, the location of the row and column of the cursor is displayed at the bottom of the screen
TabStop sets the number of spaces to skip by pressing the Tab key. Example: Set tabstop=n,n default value is 8

1) syntax highlighting
: syntax on the command to open the syntax highlighting feature in VI. In this way, VI will automatically recognize keywords, strings, and other grammatical elements in the input characters, and display them in different colors.

2) Auto Indent
The options for automatic indentation in VI are generally as follows:
Autoindent: In this form of indentation, the newly added row and the previous line have the same indentation form.

Smartindent: In this indentation mode, each row has the same indentation as the previous line, and it is correctly recognized that when the right curly brace (}) is encountered, the indent form is canceled. In addition, the ability to identify C keyword is added. If a line starts with #, this format will be treated in a special way instead of indented format. This indentation format is stronger than Autoindent.

Cindent: This is the C language indentation form, the use of such indentation in the language of the program is: C,c++,java and so on. When this indentation format is used, VI will automatically adopt the standard C language form. This indentation format is stronger than Smartindent.

You can use the following command to indent the settings:

: Set Autoindent (AI)
: Set Smartindent (SI)
: Set Cindent (CI)

3) Display line number
: Set Number (NU) Displays line numbers
: Set Nonumber (Nonu) does not display line numbers
In each user's directory, there is a VI configuration file ". VIMRC" (no words can be created by yourself). The user can edit it and enter the above command to make these settings valid for each VI. For example, add the following setting line to the. vimrc file:
Set Nu #显示行号
Set Nonu #不显示行号
Set IC #查找时不考虑大小写
Set Noic #查找时考虑大小写
Set Smartindent #自动缩进
Syntax on # syntax highlighting

GG moves the cursor to the first column in the first row of the file
V Toggle mode for Visual mode
G means move the cursor to the end of the file
This is the equivalent of selecting all the file contents,
= Enable Automatic typesetting

And gg=g is the same effect, but I am used to ...
