Change tabs to spaces in VIM

To configure VIM to use spaces instead of tabs, you can either execute VIM commands or modify the configuration file.

If you just want to modify a single file, you can execute the following commands inside VIM.

:set tabstop=2
:set shiftwidth=2
:set expandtab

In order to change the global VIM settings you can edit ~/.vimrc file

vim ~/.vimrc

set tabstop=2 shiftwidth=2 expandtab

Once tab settings are configured you can execute :retab at any time inside VIM to apply the new settings to the existing document.

More information is available on the VIM wiki site.
