How do I enable Ruby syntax highlighting in Neovim?

Question

I'm a new user of Neovim and trying to figure out how to enable syntax highlighting for Ruby.

What config should i edit?

edit:

This is my current config:

➜  ~  cat ~/.nvimrc
filetype plugin indent on
syntax on
set tabstop=2
set number
set noswapfile
" Automatically indent on new lines
set autoindent
" Copy the indentation of the previous line if auto indent doesn't know what to do
set copyindent
" Indenting a line with >> or << will indent or un-indent by 2
set shiftwidth=2
" Pressing tab in insert mode will use 4 spaces
set softtabstop=2
" Use spaces instead of tabs
set expandtab
" [SEARCH]
:set incsearch
:set hlsearch
" <Ctrl-l> redraws the screen and removes any search highlighting.
nnoremap <silent> <C-l> :nohl<CR><C-l>

And this is the error i get when loading Neovim:

➜  ~  nvim test.rb
Error detected while processing /Users/user/.nvimrc:
line    2:
E484: Can't open file /usr/local/Cellar/neovim/HEAD/share/vim/syntax/syntax.vim
Press ENTER or type command to continue

Neovim uses the xdg specification for their config files. If you are already using vim. (If you are transferring from an old version of neovim ~/.nvimrc is now $XDG_CONFIG_HOME/nvim/init.vim and ~/.nvim is now $XDG_CONFIG_HOME/nvim)

mkdir -p ${XDG_CONFIG_HOME:=$HOME/.config}
ln -s ~/.vim $XDG_CONFIG_HOME/nvim
ln -s ~/.vimrc $XDG_CONFIG_HOME/nvim/init.vim

should get you close to running with neovim (This might not work for all plugins but its a start).

All you should need in $XDG_CONFIG_HOME/nvim/init.vim is the following

filetype plugin indent on
syntax on

to get syntax highlighting for ruby.
