Vim Setup

- mac:
  brew install lua
  brew install vim --with-lua

- plugin manager: https://github.com/junegunn/vim-plug


- double check that vim has +lua support: vim --version

- if not, compile:
sudo apt-get install lua5.2 liblua5.2-dev
./configure --with-features=huge --enable-cscope --enable-pythoninterp=yes --with-python-config-dir=/usr/lib/python2.7/config-x86_64-linux-gnu --enable-multibyte --enable-fontset --disable-netbeans --enable-luainterp=yes --enable-largefile --enable-rubyinterp --enable-fail-if-missing --prefix=/opt

- .vimrc:

- finally vim, :PluginInstall, :GoInstallBinaries

- edit $PATH or use a soft link etc etc to make vim available (if you installed to /opt)
