Vim auto indent

1. Configuration File Location
Under the/etc/directory, there is a file named vimrc, which is a public Vim configuration file in the system and is valid for all users. In each user's home directory, you can create a private configuration file named ". vimrc ". For example, A. vimrc file already exists in the/root directory.
2. Set syntax highlighting
1) Open vimrc and add the following statement to highlight the Syntax:
Syntax on
2) If the syntax is still not highlighted, add the following statement to the profile file in the/etc directory:
Export term = xterm-color

3. Set Windows C/C ++ auto indent (Add the following set statement to vimrc)
1) set the (soft) tab width to 4:
Set tabstop = 4
Set softtabstop = 4
2) set the number of spaces for indentation to 4.
Set shiftwidth = 4
3) Set automatic indent: that is, the indent value of each line is equal to that of the previous line; Use noautoindent to cancel the settings:
Set autoindent
4) set the automatic indent mode in C/C ++ language:
Set cindent
5) set the specific indent mode for C/C ++ language (taking my windows style as an example ):
Set cinoptions = {s, T0, N-2, P2s, (03 S, =. 5 S,> 1 s, = 1 s,: 1 s
6) to display the line number of the text on the left, use the following statement:
Set nu
7) Add the following statement if it does not exist:
If & term = "xterm"
Set t_co = 8
Set t_sb = ^ [4% DM
Set t_sf = ^ [3% DM
Endif



This article sets Vim only for Ubuntu and Fedora systems. I have not tried other Linux versions. Please forgive me! Thank you.

In ubuntu, the vim configuration file is stored in the/etc/Vim directory. The configuration file name is vimrc.

In fedora, the vim configuration file is stored in the/etc directory. The configuration file name is vimrc.

Enter the following command on the terminal to edit the vimrc configuration file: (you can also use Shift +: Enter the corresponding command to edit the file)
Sudo Vim/etc/Vim/vimrc
Or sudo gedit/etc/Vim/vimrc

1. display the row number

Add a new line at the end of the file and enter SET nu

2. syntax highlighting
Find "syntax on" in the file and remove the double quotation marks. Double quotation marks indicate the meaning of the comment.

3. Automatic indent

Add a row at the end of the file and enter SET autoindent.
After adding a row, enter SET cindent
Autoindent indicates automatic indent, and cindent indicates automatic indent for C language syntax.

NOTE: If Vim does not take any action after the preceding settings are configured, upgrade Vim to the latest version. Generally, you only need to enter the following command on the terminal: sudo apt-Get install Vim

Have a good time using vim!
