I have been trying to figure out why my syntax highlighting won't work in Neovim for two days now.
I have included "syntax on" in my sysinit.vim as well as "filetype plugin indent on" and I get no errors when I run nvim.
When I do an "echo $VIMRUNTIME" I get the proper directory (I think. I used homebrew to install. The path is usr/local/Cellar/neovim/0.1.7/share/nvim/runtime). I have verified that the syntax folder is indeed present in that folder.
However, when I am in neovim I get no highlighting other than a red block for trailing white space. If I run ":syntax" it identifies the proper syntax (testing with python). Another strange occurrence I've identified is when I run ":syntax on" from within the editor, the colors get darker. If I turn it back off, nothing changes. As syntax is enabled in the init.vim file, I have no idea why that would change the appearance of the editor.
I'm banging my head against the wall on this. Please help! My init.vim is below. It's a work in progress!
