Vim Learning Note configuration file (VIMRC)

Vim Learning Note configuration file (VIMRC)

During the vim startup process, the configuration file is first looked up and the commands are executed. And these initialization files generally have VIMRC, GVIMRC and EXRC three kinds.

Using the: Version command, you can get details of the configuration file.

Note: If the gvim is executed, then $vimruntime/menu.vim will also be executed.

Configuration file Location

VIMRC is the primary configuration file, which has both global and user versions.

Global VIMRC files, stored in the VIM installation directory. You can use the following command to determine the installation directory for VIM:

: Echo $VIM

By default, the system VIMRC is stored in the following location:

Linux:/USR/SHARE/VIM/VIMRC

Windows:c:\program FILES\VIMRC

User vimrc files, stored in the user's home directory. You can use the following command to determine the user-headed directory:

: Echo $HOME

By default, the user vimrc is stored in the following location:

Linux:/HOME/USERNAME/.VIMRC

Windows:c:\documents and SETTINGS\USERNAME\_VIMRC

Note: The user profile takes precedence over the system configuration file.

GVIMRC is a gvim configuration file that has both global and user versions and is stored in the same directory as VIMRC.

By default, the system GVIMRC is stored in the following location:

Linux:/USR/SHARE/VIM/GVIMRC

Windows:c:\program FILES\VIM\_GVIMRC

By default, the user GVIMRC is stored in the following location:

Linux:/HOME/USERNAME/.GVIMRC

Windows:c:\documents and SETTINGS\USERNAME\_GVIMRC

exrc file, used only for backward-compatible OLVI/EX, and both global and user versions are placed in the same directory as VIMRC. Unless you use the vi-compatible mode, you do not need to focus on the EXRC configuration file.

Note: Under UNIX and Linux, Vim's configuration file is named as a hidden file that starts with a dot, while under Windows, the configuration file is named after an underscore.

Edit configuration file

You can use the following command to create a new buffer to edit the configuration file:

: Edit $MYVIMRC

You can also use the following command to create a new tab to edit the configuration file:

: Tabedit $MYVIMRC

For example, we can set the VIM option by using the following command in the configuration file:

: Syntax on "Turn on syntax highlighting features"

: Set shiftwidth=4 Setting indent width to 4 spaces

Where the single quotation mark (") is the annotation content.

Apply configuration file

After you modify the configuration file, you need to restart Vim or use the source command to apply the new settings:

: Source $MYVIMRC

We can add the following command to the configuration file and apply the configuration automatically after the Save:

Autocmd bufwritepost. VIMRC Source $MYVIMRC
