NeoVim

Install NeoVim

From the Linux section of their Installation:

To install NeoVim on Fedora:

# Replace "dnf" with "apt" for Ubuntu/Debian
sudo dnf install -y neovim python3-neovim

---

Lua setup

For LazyVim, we need to set up lua and luarocks (the package manager for Lua modules)

Install lua and it’s development headers

• Check if lua and the development variant of that package is installed:

  # Check installed lua version (if any)
  lua -v
  
  # Check if development headers are available
  plocate lua.h
  # The output should mention header files like: "/usr/include/lua.h", "/usr/include/lua.hpp"
  

• If not installed, install it as below. Ubuntu command referred from here

  # For Ubuntu/Debian (apt):
  sudo apt install -y lua5.4 liblua5.4-dev
  
  # For Fedora (dnf):
  sudo dnf install -y lua lua-devel
  sudo updatedb
  

  Now verify they are installed via the previous commands

Set up luarocks

Following the LuaRocks install guide:

• Download the tarball. Extract it’s contents and cd into that folder:

  wget https://luarocks.org/releases/luarocks-3.11.1.tar.gz
  tar zxpf luarocks-3.11.1.tar.gz
  cd luarocks-3.11.1
  

• Run the configuration script:

  # To view optional arguments
  ./configure --help
  
  # Running the script
  ./configure
  
  # If above run fails, specify the lua version and header file directory as arguments
  ./configure --lua-version=5.4 --with-lua-include=/usr/include
  

  It’s output would look something like:

  Configuring LuaRocks version 3.11.1...
  
  Lua interpreter found: /usr/bin/lua
  Checking if /usr/bin/lua is Lua version 5.4... yes
  lua.h found: /usr/include/lua.h
  unzip found in PATH: /usr/bin
  
  Done configuring.
  
  LuaRocks will be installed at......: /usr/local
  LuaRocks will install rocks at.....: /usr/local
  LuaRocks configuration directory...: /usr/local/etc/luarocks
  Using Lua from.....................: /usr
  Lua include directory..............: /usr/include
  
  * Type make and make install:
    to install to /usr/local as usual.
  * Type make bootstrap:
    to install LuaRocks into /usr/local as a rock.
  

• Build from the source code and install:

  make && sudo make install
  

• Install a luarocks module to test it out:

  sudo luarocks install luasocket
  

• Check if the module gets detected and imported properly:

  lua
  Lua 5.3.5 Copyright (C) 1994-2018 Lua.org, PUC-Rio
  > require "socket"
  

  The output should look something like: table: 0x5584a1343f70 /usr/local/share/lua/5.4/socket.lua. Press Ctrl d to exit the lua interpreter

  • If you get error like module 'socket' not found, you need to add various paths to your Shell. Note down the output of luarocks path

  • Only append the luarocks specific entries to existing PATH. Copy LUA_PATH, LUA_CPATH as-it-is. So finally, the lines to add in your shell profile file (~/.zshrc or ~/.bashrc) would be like:

    export PATH=$PATH:"$HOME/.luarocks/bin:/usr/local/bin"
    export LUA_PATH=$LUA_PATH:"/home/kumar/.luarocks/share/lua/5.4/?.lua;/home/kumar/.luarocks/share/lua/5.4/?/init.lua;/usr/local/share/lua/5.4/?.lua;/usr/local/share/lua/5.4/?/init.lua"
    export LUA_CPATH=$LUA_CPATH:"$HOME/.luarocks/lib/lua/5.4/?.so;/usr/local/lib/lua/5.4/?.so"

LazyVim setup

As per the LazyVim Installation docs:

• Back-up your current NeoVim config files:

  # required
  mv ~/.config/nvim{,.bak}
  
  # optional but recommended
  mv ~/.local/share/nvim{,.bak}
  mv ~/.local/state/nvim{,.bak}
  mv ~/.cache/nvim{,.bak}
  

• Clone their start-kit repo:

  git clone https://github.com/LazyVim/starter ~/.config/nvim
  

• Remove the .git/ folder, so you can add it to your own repo later:

  rm -rf ~/.config/nvim/.git
  

• Start NeoVim. LazyVim will initialize and lazy-load all your plugins

  nvim
  

• Enter :checkhealth to see status of plugins installed
