Installation

Dependencies

If your machine on Debian/Ubuntu based Linux distro you can just run to install neovim :

sudo apt install neovim

If you want to use the latest version and your distro supports Ubuntu PPA you can install neovim using this PPA:

sudo add-apt-repository ppa:neovim-ppa/unstable
sudo apt-get update

You can also use snap

sudo snap install --edge nvim --classic

Other methods of installation are available in the official repository of Neovim

There are several ways of installing NodeJS:

NVM - one of the easiest way

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash
# restart terminal (https://github.com/nvm-sh/nvm#troubleshooting-on-linux)
nvm install --lts

Warning! It can cause problems if you are using Neovim over SSH session.

Downloading tar.xz from official website
via NodeSource Node.js Binary Distributions by a package manager

ctags can be installed by the next command on Debian/Ubuntu:

sudo apt install exuberant-ctags

Installation of clangd:

https://apt.llvm.org/ - clang + clangd

https://snapcraft.io/clangd - snap

To install pynvim in a terminal by the command:

pip3 install pynvim

You can choose any Nerd font that is suitable for you from Patched fonts repository. Installation guide is also provided.

You can also select option that I am using you can execute:

cd ~/.local/share/fonts && curl -fLo "Droid Sans Mono for Powerline Nerd Font Complete.otf" https://github.com/ryanoasis/nerd-fonts/raw/master/patched-fonts/DroidSansMono/complete/Droid%20Sans%20Mono%20Nerd%20Font%20Complete.otf

And then, select Dorid Sans Mono Nerd font in the settings of your terminal.

At the end

Put init.vim into ~/.config/nvim/ folder. Sometimes there is no nvim so you can create it manually. Then run nvim +PlugInstall in a terminal and press y into dialog screen. All plugins and LSPs will be downloaded automatically.

Also, it is possible to configure Coc using nvim +CocConfig command or editing ~/.config/nvim/coc-settings.json. Personally, I use:

{
    "clangd.path": "/usr/bin/clangd-10",
    "suggest.noselect": false,
    "java.jdt.ls.vmargs": "-javaagent:/usr/local/share/lombok/lombok.jar",
}
