Install

Follow the install guide Installing Neovim.


Default ini files are located at ~/.config/nvim/init.vim. To import Vim settings (FAQ :help nvim-from-vim)

mkdir ~/.config
ln -s ~/.vim ~/.config/nvim
ln -s ~/.vimrc ~/.config/nvim/init.vim

Configure nvim as default vim alternative:

sudo update-alternatives --install /usr/bin/vi vi /usr/bin/nvim 60
sudo update-alternatives --config vi
sudo update-alternatives --install /usr/bin/vim vim /usr/bin/nvim 60
sudo update-alternatives --config vim
sudo update-alternatives --install /usr/bin/editor editor /usr/bin/nvim 60
sudo update-alternatives --config editor


Ruby support

Must install neovim rubygem:

sudo apt install ruby-dev
sudo gem install neovim

Plugin manager

We install vim-plug:

curl -fLo ~/.config/nvim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Plugins

Content of ~/.config/nvim/init.vim:

Reload the init script and install plugins:

:so $MYVIMRC
"... or ':so %' if it is current file
:PlugInstall

To update plugins:

:PlugUpdate
To test
  • vim-airline, vs powerline, vs vim-bufferline
  • Color theme solarized.

Troubleshooting

True color and italic support

There are lot of discussion about true color and italic support in the terminal. Below the list of relevant posts.

All in all the solution for me involved to at least:

  • Upgrade to Ubuntu Xenial 16.04, to get newest Gnome Terminal and Terminator/gtk3 on recent VTE.
  • Upgrade to tmux 2.2 (only if using tmux).
  • Do a total reset of the account configuration.
  • Fiddle a bit with the terminfo (still not sure what was the exact recipe though).
  • Use gruvbox as theme (not solarized, which does not work in terminal).

To test, first verify that the color theme works correctly in gvim.

To Do

Gui
Color scheme
  • Solarized
