Is it possible to apply vim configurations without restarting?

Question

I want to edit .vimrc file from Vim and apply them without restarting Vim.

Answer 1

Yes, just use the :so % command while editing your .vimrc.

If you want vim to auto-reload your configuration, you must add the following commands :

augroup myvimrchooks
    au!
    autocmd bufwritepost .vimrc source $MYVIMRC
augroup END

the grouping of autocommand is here to avoid "exponential" reloading if you save several times your configuration.
