1. Create a. vimrc file under your home directory (///). Console input vi ~/.VIMRC carriage return.
2. Enter the following text in the. vimrc file:
Set tabstop=4
Set softtabstop=4
Set shiftwidth=4
Set Noexpandtab
Set Nu
Set Autoindent
Set Cindent
which
Tabstop: Indicates the length of the number of spaces that a tab displays, by default, 8.
Softtabstop: Indicates the length of the indent when pressing the backspace bar while in edit mode, especially useful when using Expandtab.
Shiftwidth: Indicates the length of each level of indentation, generally set to be the same as softtabstop. When set to Expandtab, the indentation is represented by an empty glyd, and noexpandtab is a tab representation of an indentation.
Nu: Indicates the line number is displayed.
Autoindent: Indicates automatic indentation.
Cindent: is specifically for C language auto indent.
3. Save and exit after Setup. Running source ~/.VIMRC makes the configuration file effective, and you can experience the width of 4 spaces that are indented when you press the TAB key and the automatic indentation of line breaks when you program C.
