Stop annoying MacVim tooltips from appearing

MacVim has an acknowledged bug wherein tooltips appear on mouseover in Ruby code.

Normally, one could remedy the problem by setting noballooneval in their ~/.vimrc file:

set noballooneval

Unfortunately, that setting is being overwritten. To determine what file is overwriting the vimrc setting, run the following command in a Vim window:

:verbose set ballooneval?
> Last set from /Applications/MacVim.app/Contents/Resources/vim/runtime/autoload/netrw.vim

The offending file is a part of MacVim itself. This really requires a patch to MacVim. Until then, edit the offending file:

vi /Applications/MacVim.app/Contents/Resources/vim/runtime/autoload/netrw.vim

To do so, I commented out every line with set beval. Fyi: I’m running MacVim snapshot 61. I altered lines 317 and 2609.

Before:

set beval

After:

" set beval
