Question

Its a bit weird, I wanted to deactivate automatic backups in gVIM when saving, so I placed set nobackup in the top of the file _vimrc and it didn’t work. Then I placed that line below the following lines:

set nocompatible
source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim
behave mswin

and it worked.

basically set nobackup doesn’t works like this:

set nobackup

 set nocompatible
    source $VIMRUNTIME/vimrc_example.vim
    source $VIMRUNTIME/mswin.vim
    behave mswin

and but works like this:

 set nocompatible
    source $VIMRUNTIME/vimrc_example.vim
    source $VIMRUNTIME/mswin.vim
    behave mswin

set nobackup

Is this normal? Do VIM settings interfere with other settings?

Answer 1

source $VIMRUNTIME/vimrc_example.vim
source $VIMRUNTIME/mswin.vim

means that vim runs the configuration in those files before loading the lines after. As “just somebody” said, in vimrc_example.vim, the backup is activated, so, in your first example, your first set the nobackup and then it’s unactivated by the .vim file.
