How to turn-off a plugin in Vim temporarily?

Question

I have multiple plugins in Vim and some of them modify the default behavior of Vim. For example I use Vimacs plugin, which makes Vim behave like emacs in the insert mode alone. Sometime I want to turn off the Vimacs plugin without moving the vimacs.vim out of the plugins directory. Is there a way to do it?

Answer 1

You can do this if you use a plugin manager like Vundle or Pathogen, which will keep the plugin in its own directory underneath the ~/.vim/bundle/ directory.

In that case, just find out the runtimepath of the vimacs plugin with the following command:

set runtimepath? 

Let's say it's ~/.vim/bundle/vimacs.

Then, put this command in your .vimrc:

set runtimepath-=~/.vim/bundle/vimacs 

To load vimacs, just comment that line out and relaunch Vim (or source your .vimrc).

Answer 2

See which variable vimacs check on start. On the begin of the script file find something Like if exists('g:vimacs_is_loaded").... Then set this variable in your .vimrc or while start vim with vim --cmd "let g:vimacs_is_loaded = 1".
