About

This configuration is based on josean-dev, ThePrimeagen and miltonllera/config, however some shortcuts have been changed and some plugins have been organized to work on projects with typescript, javascript and react.

History

I have been using coc.nvim for the last three years and decided to migrate to Lua and I am really happy with the improvement and control of each of your utilities. I added and configured the plugins in the way that I have used them before, that is why this fork will remain independent.

The template that Milton left, which has given the main focus to Linux and Mac. I have expanded the guide for Windows since it is my development environment.

I have added some plugins recommended by the guys from lunarVim and added some validations and plugins they use, achieving a very stable and agile version.

A Neovim configuration using Lua, with the minimal number of pluggins I need for programming. Different language servers available through the LSP protocol provide code completion and analysis.

This readme exist so I don't have to remember how to do all these things when setting up a new machine.

🛠 Setting up

Windows

nvim Home

Install Chocolatey

Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))

Install Neovim

choco install neovim

Install Git

choco install git

Install Node

Global packages for npm (update your packages)

 npm install -g neovim
 npm install -g prettier
  • Clone the repository inside off this folder or download the last release
git clone https://github.com/i-xarlos/neovim-config.git ~/AppData/Local/nvim
  • Neovim configuration file
~/AppData/Local/nvim

Install Terminal You can download and install it from the microsoft store and choose your favorite font

Please review nvim.tressitier windows support

# Mingw toolchain
choco install mingw

# LLVM (Clang)
choco install llvm

Optionally:

 choco install chocolateygui
# Install nvm
choco install nvm

# Nvm install node versions
nvm install 16.17.1

Linux

The first step is to install the correct version of Neovim. Most plugins require version 0.5 or above, but treesitter actually requires >= 0.5.1. to work. Version 0.6 has now been relased, which means the previous comment is deprecated. Versions can be installed using snap:

# For stable versions
sudo snap install --beta nvim --classic

# For nightly versions
sudo snap install --edge nvim --classic

We also need to install the node package manager npm since most language servers are installed that way.

sudo apt install npm

MacOS

Assume brew is installed, then installing Neovim is straighforward:

# For stable version
brew install neovim

# for nightly version
brew install --HEAD neovim

# To update
brew reinstall neovim

Additionally, you may need to configure the Option key to behave like Alt. In iTerm2, this can be done in Preferences -> Profiles -> Keys. Change the left option behaviour to Esc+. For kitty, you need to set macos_option_as_alt left (defualt is no) in the terminal's config file. Restarting the terminal (Command + Q, then restart) is required for this to take effect.

⭐ Installing the configuration

Clone the repo into Neovim's installation folder (usually /home/<usr>/.config/nvim):

git clone https://github.com/i-xarlos/neovim-config.git ~/.config/nvim
cd ~/.config/nvim

This will create a folder with the configuration with the following structure is as follows:

|- lua
|  |- config/
|       |- core/
|       |- defaults/
|       |- lazy/
|            |- init.lua
|       |- plugins/
\- init.lua

This structure is important since Lua will not load files that are not located inside lua. The file init.lua loads all the modules located inside this folder to set the configuration. Most of the names are self explanatory. The most important file here is plugins.lua, which is the module that loads the relevant plugins. Some of the most important plugins are:

  1. lazy: Manage the plugins.
  2. lspconfig: provides a client for the different language servers using the Language Server Protocol (LSP).
  3. cmp: Auto-complete functionality. Recommended by the core Neovim team.
  4. treesitter: Syntax highlighting and other functionality.
  5. NvimTree: File explorer written in Lua.
  6. gitsigns: Git gutter highlighting and hunk management in buffer.
  7. telescope: Fuzzy finder.
  8. lualine: A status line written in Lua which is similar to vim-airline.

There are some more packages that are dependencies of the ones mentioned above, and some for formatting and theming as well. Adding new plugins is simple using the use function:

return{
  '<author>/<plugin-repo>',
   config = function() require('<plugin-name>').setup({}) end,
}

This will load a plugin with it's standard configuration. For more complex configurations, we create the relevant file in lua/plugins (eg. lua/plugins/foo.lua) and load it using the require function along with any other option we wish to pass on to the use function:

return {
  '<author>/<plugin-repo>',
  config = function() require('plugin/<plugin-name>') end,
  -- Optionally require other plugins.
  requires = '<author>/<required-plugin-repo>'
  -- Other functionality
}

Notice that the file type is omitted from this call.

Install and update plugins using packer

#nvim command
:Lazy

📋 Auto-completion

The auto-complete functionality is achieved by using nvim-cmp to attach the relevant language servers to the buffers containing code. Most servers only require that the on attach function is specified so that different motions are available. Currently, the common function to attach a server to a buffer is located in lua/lsp/utils.lua . It will enable common key mappings for all language servers to display code completion.

Some further notes

Inline error messages are disabled in the current configuration. They create a lot of clutter. To enable them back, comment the code on line 34 of lua/options.lua. This is a nvim option related to it's lsp interface, not something provided by the servers themselves.

Web-dev Icons

To visualize fancy icons and separators, a patched font must be installed. Nerd Fonts has many already patched and offers instructions on how to create new ones (I don't recommend). To install a patched font follow these instructions:

  1. Head to the repo and download the font. I use Robot Mono.
  2. Copy the file to the relevant folder:
  • Linux: ~/.local/share/fonts/.
  • MacOS: /Library/Fonts'.
  1. Change the font in the terminal emulator's settings to the patched font.

Yaml issues: Please verify: nvim-treesitter/nvim-treesitter#3587

Nerd Fonts with Kitty

If using kitty as default terminal, then the procedure above won't work. First, kitty does not support non-monospaced fonts due to how it renders text. Second, the fonts cannot be patched. In fact, kitty takes care of patching on it's own which is great. To install the fonts follow the instructions in this blog, which are straighforward.

TL;DR for MacOS:

  1. Download and install the fonts and put the file Symbols-2048-em Nerd Font Complete.tff (or whatever subset you decide to use) in the Library/Fonts/ folder for system wide use, or the local variant.
  2. If the glyphs aren't displayed by default, then they can be specified manually by following the instructions.
  3. Refresh the fonts cache.

📗 Shortcuts:

If you need more information you can find more shortcuts in options.lua and keymaps.lua:

|- lua
|  |- core/
|  |  | - options.lua
|  |  | - keymaps.lua

Some of the most used shortcuts:

Attributions

The structre of this config was based on yashguptaz's config and tutorial which helped me understand the basics of using Lua with Neovim.

I've also stolen code from different sources which means it might be hard to acknowledge all of them explicitly though most of them are from the associated plugin's documentation.
