Clang

Install clang and clangd ( See docs ):
Note: change 14 with your desired version of clang

$ sudo apt install clang-14 clangd-14
$ sudo update-alternatives --install /usr/bin/clangd clangd /usr/bin/clangd-14 100

rust-analyzer

for rust support install rust-analyzer:

$ mkdir -p ~/.local/bin
$ curl -L https://github.com/rust-analyzer/rust-analyzer/releases/latest/download/rust-analyzer-x86_64-unknown-linux-gnu.gz | gunzip -c - > ~/.local/bin/rust-analyzer
$ chmod +x ~/.local/bin/rust-analyzer

pyright

for python support you need pyright first make sure you have nodejs and npm installed and then run:

$ npm i -g pyright

Other language servers

for other languages refer to lspconfig documentation:
https://github.com/neovim/nvim-lspconfig/blob/master/doc/server_configurations.md

Configurations

Neovim Plugin manager

Use any plugin manager you like, I used packer:

git clone --depth 1 https://github.com/wbthomason/packer.nvim ~/.local/share/nvim/site/pack/packer/start/packer.nvim

Copy Configurations

Copy repo into ~/.config/nvim/ (THIS DELETES OLD neovim CONFIGURATIONS):

$ rm -rf ~/.config/nvim/
$ rm -rf ~/.local/share/nvim/
$ git clone https://github.com/RYNEQ/nvim-config ~/.config/nvim/

Install plugins

If you use packer open neovim and type :PackerSync Otherwise refer to your plugin manager's plugin installation method

Fonts

Install Nerd-Fonts:

$ cd ~
$ git clone --depth 1 https://github.com/ryanoasis/nerd-fonts
$ cd nerd-fonts
$ ./install.sh

Configure terminal font

• Goto your terminal's font configuration and select a monospace font from nerd-fonts installed fonts (e.g. Hack)
• Close Terminal and open it again
