My Nvim Configuration

Neovim Last commit Github issues CI Status License

💻 This configuration works on my Manjaro Linux as well as on my macOS and requires Neovim >= 0.8!

Have a look at my rice how my Linux machine is configured and at my mac-setup how my MBP is configured. My dotfiles are also on GitHub.

Motivation

There are many great Neovim configurations (see Inspiration), that give you a pleasant experience right out of the box, available. However, I am a long time (Neo)Vim user with a specific workflow and needs. Additionally, I do not have any Lua background and was not willing to spent too much time into that. Therefore, it was quite hard for me to customize and strip down the existing configs to my needs especially because the code is quite sophisticated.

I decided to move to my own fresh Lua based Neovim from my good old vimrc trying to accomplish the following principles.

Principles

  1. Migrate to Lua based alternative plugins respectively use only Lua based plugins (if possible).
  2. Keep the config as maintainable as possible knowing that this would possibly impact the code quality.
  3. Modular and meaningful directory structure and file naming.
  4. Just make it work and not make it beautiful 😃. Of course, Neovim itself must look beautiful, but my focus is not on beautiful code or on utilizing all Lua features.

Try out

If you have Docker on your system you can try out this config via the provided Dockerfile

💡 Due to installing required tools like LSPs, CLI apps, etc. the image is approximately 3 GB large

Build the image

There are some issues with building a multi architecture Docker image via GitHub Action. Until I sorted that out, you can build the Docker image locally on your own

docker build -t nvim .

Just start nvim

docker run --name nvim --rm -it nvim

Mount a local directory (to ~/mount) and start nvim

docker run --name nvim --rm -it -v ${HOME}/tmp:/home/nvim/mount nvim

Start container in bash instead of nvim

docker run --name nvim --rm -it --entrypoint=/bin/bash nvim

Installation

I created an installation script that sets up all required tools on a fresh machine to work with my Neovim config.

For now, it works on Debian/Ubuntu and Arch. MacOS will be added soon.

USE AT YOUR OWN RISK!!

Requirements

There are some tools that are required in order to use some features/plugins:

Tools

For neo-tree delete functionality:

For Latex functionality:

LSPs, Formatting, Linters, DAP

The following programs should be installed on your system so that the appropriate tools can be installed:

  • Go
  • Python
  • NodeJs > 12
  • Cargo

Go

Go related dependencies are managed by go.nvim and are installed by running :GoInstallBinaries (when a Go file is loaded). They are installed in your $GOPATH.

All other

All other dependencies are managed by Mason. Tools are installed by running :MasonToolsInstall (in vim.fn.std path("data") .. "mason"). [Mason requirements](https://GitHub.com/William beman/mason.nvim#requirements) must be available on your system.

Each plugin to be installed is defined in ./lua/core/plugins/ in a separate file.

User configuration

The intention of my Neovim configuration was never to be a fully customizable "distribution" like LunarVim, SpaceVim, etc. but from time to time I like to change my color scheme and the idea of making this configurable came to my mind. Based upon this idea I implemented some further lightweight configuration options that might be useful.

All options can be found in ./lua/core/settings.lua.

Adding LSPs

You can add LSPs via lsp_servers in settings.lua. The server will be installed by Mason und loaded by nvim-lspconfig. If you want to pass settings for the LSP have a look at ./lua/core/plugins/lsp/settings/ how to add settings for specific LSPs.

Remove plugins

You can remove unwanted plugins by just removing the appropriate file in ./lua/core/plugins/. Lazy will take care of removing the plugin.

Keep in mind that some plugins are configured to work in conjunction with other plugins. For instance, autopairs is configured in ./lua/vim/config/treesitter.lua. For now there is no logic implemented that cross-checks such dependencies.

Add plugins

If you want to follow my method adding a plugin is straight forward:

Create a file in ./lua/core/plugins/ following the expected format of Lazy.

Open another instance of Neovim (I always try to keep one running instance of Neovim open in case I messed up my config) and run Lazy sync.
