LunarVim provides neovim configuration files that take advantage of tree-sitter and language server protocol. The configuration is written in lua. ## Why do I want tree-sitter and LSP? - Normally, an editor uses regular expression parsing for things like highlighting and checking the syntax of your file. Each time you make a change, the editor must re-parse the entire file. Tree-sitter, on the other hand, transforms text into a syntax tree. Each time you make a change, only the parts of the code that change need to be parsed. This greatly improves the speed of parsing. This can make a huge difference when editing large files. - Neovim 0.5 including language server protocol means your editor can provide: code actions, completions, formatting, navigating to definitions, renaming, etc. The language server only has to be written once and will work on any editor that supports LSP. Any improvements made to the language server will immediately be used by all editors that support LSP. # Project Goals - This project aims to help one transition away from VSCode, and into a superior text editing experience. (Just making this clear) - This is also a community project, if you would like to see support for a feature or [language](https://github.com/neovim/nvim-lspconfig/blob/master/CONFIG.md) consider making a PR. - This project will do it’s best to include core features you would expect from a modern IDE, while making it easy to add or remove what the user wants. # Install In One Command! Make sure you have the newest version of Neovim (0.5). ``` bash bash <(curl -s https://raw.githubusercontent.com/ChristianChiarulli/lunarvim/master/utils/installer/install.sh) ``` After installation run `nvim` and then `:PackerInstall` ## Get the latest version of Neovim Some operating systems package versions of Neovim 0.5. You can install those or you can follow the steps below to compile from source. Compiling from source is the recommended method. First, get the dependencies. For distributions other than Ubuntu or Arch go [here](https://github.com/neovim/neovim/wiki/Building-Neovim#build-prerequisites) ``` bash #Ubuntu sudo apt-get install gettext libtool libtool-bin autoconf automake cmake g++ pkg-config unzip build-essential #Arch sudo pacman -S base-devel cmake unzip ninja tree-sitter ``` Download and compile Neovim ``` bash cd $(mktemp -d) git clone https://github.com/neovim/neovim --depth 1 cd neovim sudo make CMAKE_BUILD_TYPE=Release install cd .. sudo rm -r neovim ``` or if you are on Arch you can get it from the AUR ``` bash yay -S neovim-git ``` If you are on Gentoo you have to emerge the 9999 neovim version with luajit as the lua single target ## Manual install First make sure you have version [0.5 of neovim](#get-the-latest-version-of-neovim). Back up your current configuration files ```bash mv ~/.config/nvim ~/.config/nvim.bak ``` Install xclip, python3, ripgrep, fzf, npm, nodejs, pip, and ranger with the package manager for your distribution. ```bash # Ubuntu sudo apt install xclip python3-pip nodejs npm ripgrep fzf ranger libjpeg8-dev zlib1g-dev python-dev python3-dev libxtst-dev python3-pip # Arch sudo pacman -S xclip python python-pip nodejs npm ripgrep fzf ranger # Fedora sudo dnf groupinstall "X Software Development" sudo dnf install -y xclip python3-devel pip nodejs npm ripgrep fzf ranger pip3 install wheel ueberzug # Gentoo sudo emerge -avn sys-apps/ripgrep app-shells/fzf app-misc/ranger dev-python/neovim-remote virtual/jpeg sys-libs/zlib sudo emerge -avn dev-python/pip # Optional. Enable npm USE flag with flaggie sudo flaggie net-libs/nodejs +npm sudo emerge -avnN net-libs/nodejs # Mac brew install lua node yarn ripgrep fzf ranger sudo curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py python3 get-pip.py rm get-pip.py ``` Install tree-sitter. To globally install packages without the need for sudo follow [this guide](https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally) ```bash npm install -g tree-sitter-cli ``` Install ueberzug, neovim-remote, and pynvim with pip3 ```bash pip3 install ueberzug neovim neovim-remote pynvim --user ``` Clone LunarVim and Packer ```bash git clone https://github.com/wbthomason/packer.nvim ~/.local/share/nvim/site/pack/packer/start/packer.nvim git clone https://github.com/ChristianChiarulli/lunarvim.git ~/.config/nvim ``` Install plugins ``` nvim -u $HOME/.config/nvim/init.lua +PackerInstall ``` ## Troubleshooting installation problems If you encounter problems with the installation check the following: 1. Make sure you have at least version 0.5 of neovim. 2. Make sure neovim was compiled with luajit. ```bash # The output of version information should include a line for: LuaJIT nvim -v ``` 3. If you ran the [quick-install script](#install-in-one-command) using sudo, follow the steps to [uninstall](#uninstalling) and try again without sudo. 4. Make sure the [dependencies](#useful-programs) were installed. 5. Make sure your plugins are installed and updated. Run :PackerSync # Getting started ## Home screen The home screen is a plugin called [Dashboard](https://github.com/glepnir/dashboard-nvim). It uses the [Telescope](https://github.com/nvim-telescope/telescope.nvim) plugin to find files or find words within files. The home screen provides a link to load saved Sessions. The home screen links to the settings file located at this path: \~/.config/nvim/lv-settings.lua ## Leader and Whichkey The default leader key is set to <Space>. Pressing it will also open up [Whichkey](https://github.com/folke/which-key.nvim). Whichkey will help you easily access many of the default keybindings. Whichkey defines keymappings in this file: \~/.config/nvim/lua/lv-which-key/init.lua ## Other key bindings Other key bindings can be found in \~/.config/nvim/lua/keymappings.lua If you already have a set of keybindings in vimscript that you prefer, source your vimscript file from \~/.config/nvim/init.lua Example: ``` lua vim.cmd('source ~/.config/nvim/vimscript/keymappings.vim') ``` Or you can translate your old bindings to lua and keep them in the provided keymappings file. Follow the lua guide available [here](https://github.com/nanotee/nvim-lua-guide) ## Important Configuration files | Path | Description | |-------------------------------------|----------------------------| | \~/.config/nvim/lv-settings.lua | The main settings file | | \~/.config/nvim/lua/keymappings.lua | Key bindings | | \~/.config/nvim/lua/plugins.lua | Add or remove plugins here | # Install your own plugins The steps for configuring your own plugin are: 1. Add the plugin to `plugins.lua` 2. If the plugin requires configuration, create a configuration file for it 3. If you created a configuration, require the file in `init.lua` 4. Use Packer to download and install the plugin Please note that every plugin will require different configuration steps. Follow the instructions provided by the README of plugin you're interested in. If those instructions are written in lua, copy and paste the code they provide. If the instructions are written in vimscript, either translate the code to lua or wrap the vimscript in this lua function: ```lua vim.cmd([[ YOUR_VIMSCRIPT_GOES_HERE ]]) ``` ## An example installation of the colorizer plugin 'use' is a function provided by the Packer plugin. In the example below, we tell Packer to optionally load the plugin. This means the plugin will not start unless some other function manually loads it. The 'require_plugin' function is part of LunarVim. It loads the plugin. ``` lua # ~/.config/nvim/lua/plugins.lua use {"norcalli/nvim-colorizer.lua", opt = true} require_plugin("nvim-colorizer.lua") ``` From the [ README ](https://github.com/norcalli/nvim-colorizer.lua) we find out [ Colorizer ](https://github.com/norcalli/nvim-colorizer.lua) is written and configured in lua. Colorizer provides a setup function which must be called for the plugin to work correctly. So we create a folder 'lv-colorizer' and a file 'init.lua'. And populate the file with the configuration mentioned in the [ README ](https://github.com/norcalli/nvim-colorizer.lua) ``` lua # ~/.config/nvim/lua/lv-colorizer/init.lua require'colorizer'.setup() ``` We created the lua/lv-colorizer/init.lua file. Creating this file means that we've created a module. Now we need to make sure this module gets loaded when we start neovim. 'require' is a lua function that loads a module. ``` lua # ~/.config/nvim/init.lua require('lv-colorizer') ``` ``` lua :PackerCompile :PackerInstall ``` The example above loads the plugin when neovim starts. If you want to take advantage of Packer's built-in lazy loading, do not use the 'require_plugin' function. Instead, define the loading strategy in Packer's 'use' method. For a more in-depth explantion, read the [Packer docs](https://github.com/wbthomason/packer.nvim) ## Finding plugins If you want to find other plugins that take advantage of neovim’s latest features go [here](https://github.com/rockerBOO/awesome-neovim) # Using Packer [Packer](https://github.com/wbthomason/packer.nvim) manages your installed plugins. Any time you make changes to your list of plugins in \~/.config/nvim/lua/plugins.lua you must first run the command :PackerCompile then :PackerInstall. \#\# Packer commands ``` bash -- You must run this or `PackerSync` whenever you make changes to your plugin configuration :PackerCompile -- Only install missing plugins :PackerInstall -- Update and install plugins :PackerUpdate -- Remove any disabled or unused plugins :PackerClean -- Performs `PackerClean` and then `PackerUpdate` :PackerSync -- View the status of your plugins :PackerStatus ``` ## Packer reports missing plugins If you get an error message about missing plugins and the above commands do not work, remove the plugin directory and reinstall from scratch. ``` bash rm -rf ~/.local/share/nvim/site :PackerCompile :PackerInstall ``` # Clipboard Support - On Mac `pbcopy` should be built-in - Ubuntu ```bash sudo apt install xclip ``` - Arch ```bash sudo pacman -S xclip ``` - WSL2 Make sure ~/bin is in your path in this case. ```bash curl -sLo/tmp/win32yank.zip https://github.com/equalsraf/win32yank/releases/download/v0.0.4/win32yank-x64.zip unzip -p /tmp/win32yank.zip win32yank.exe > /tmp/win32yank.exe chmod +x /tmp/win32yank.exe mv /tmp/win32yank.exe ~/bin ``` # LSP Neovim comes bundled with a language client but not a language server. To install a supported language server: ``` md :LspInstall ``` See [LspInstall](https://github.com/kabouzeid/nvim-lspinstall) for more info. In order for Java LSP to work, edit `~/.local/share/nvim/lspinstall/java/jdtls.sh` and replace `WORKSPACE="$1"` with `WORKSPACE="$HOME/workspace"` Most common languages should be supported out of the box, if yours is not I would welcome a PR ## Lsp errors LunarVim lists the attached lsp server in the bottom status bar. If it says ‘No client connected’ use :LspInfo to troubleshoot. ### Understanding LspInfo 1. Make sure there is a client attached to the buffer. 0 attached clients means lsp is not running 2. Active clients are clients in other files you have open 3. Clients that match the filetype will be listed. If installed with :LspInstall the language servers will be installed. 4. ‘cmd’ must be populated. This is the language server executable. If the ‘cmd’ isn’t set or if it’s not executable you won’t be able to run the language server. * In the example below ‘efm-langserver’ is the name of the binary that acts as the langserver. If we run ‘which efm-langserver’ and we get a location to the executable, it means the langauge server is installed and available globally. * If you know the command is installed AND you don’t want to install it globally you’ll need to manually set 'cmd' in the language server settings. * Configurations are stored in ~/.config/nvim/lua/lsp/ The settings will be stored in a file that matches the name of the language. e.g. python-ls.lua * ‘identified root’ must also be populated. Most language servers require you be inside a git repository for the root to be detected. If you don’t want to initialize the directory as a git repository, an empty .git/ folder will also work. 5. Some language servers get set up on a per project basis so you may have to reinstall the language server when you move to a different project. ### Example configurations [ ======== LSP NOT running ======== ] ``` md 0 client(s) attached to this buffer: 0 active client(s): Clients that match the filetype python: Config: efm cmd: /Users/my-user/.local/share/nvim/lspinstall/efm/efm-langserver cmd is executable: True identified root: None custom handlers: Config: pyright cmd: /Users/my-user/.local/share/nvim/lspinstall/python/node_modules/.bin/pyright-langserver --stdio cmd is executable: True identified root: None custom handlers: textDocument/publishDiagnostics ``` --- [ ======== LSP IS running ======== ] ``` md 2 client(s) attached to this buffer: pyright, efm Client: pyright (id 1) root: /home/my-user/workspace/canary filetypes: python cmd: /home/my-user/.local/share/nvim/lspinstall/python/node_modules/.bin/pyright-langserver --stdio Client: efm (id 2) root: /home/my-user/workspace/canary filetypes: lua, python, javascriptreact, javascript, typescript, typescriptreact, sh, html, css, json, yaml, markdown, vue cmd: /home/my-user/.local/share/nvim/lspinstall/efm/efm-langserver ``` ### Last resort If you still have problems after implementing the above measures, rule out plugin problems with the following. This reinstalls your plugins and language servers. ``` md rm -rf ~/.local/share/nvim/site :PackerCompile :PackerInstall :LspInstall python <-- REPLACE WITH YOUR OWN LANGUAGE :LspInstall efm <-- REPLACE WITH YOUR OWN LANGUAGE ``` For a more in depth LSP support: [link](https://github.com/neovim/nvim-lspconfig/blob/master/CONFIG.md) # Useful Programs LunarVim depends on the following: ``` bash ranger ueberzug ripgrep pynvim neovim-remote ``` # EFM server In order for linters and formatters to work you will need to install `efm-langserver` ``` vim :LspInstall efm ``` # Formatters and Linters **Python** ``` bash pip3 install --user flake8 pip3 install --user yapf ``` **Lua** ``` bash luarocks install --server=https://luarocks.org/dev luaformatter ``` **Yaml, Json, Javascript, HTML, CSS** ``` bash npm install -g prettier ``` **Markdown** ``` bash pandoc ``` # De-bugging To set up your particular debugger, look here: [link](https://github.com/mfussenegger/nvim-dap/wiki/Debug-Adapter-installation) # VSCodium I recommend you support Free/Libre versions if you plan to use VSCode: - [VSCodium](https://vscodium.com/) - Article to get you set up with VSCodium: [link](https://www.chrisatmachine.com/Neovim/22-vscodium-neovim/) After installing the [Neovim extension](https://github.com/asvetliakov/vscode-neovim) in VSCode I recommend using this alongside the VSCode [which-key](https://github.com/VSpaceCode/vscode-which-key) extension You will also need `settings.json` and `keybindings.json` which can be found in utils/vscode\_config Point the nvim path to your `nvim` binary Point your `init.vim` path to: ``` vim $HOME/.config/nvim/vimscript/lv-vscode/init.vim ``` # Color schemes Color schemes are provided by [this repository](https://github.com/ChristianChiarulli/nvcode-color-schemes.vim). Follow that link for information about editing specific colors for a color scheme. The provided color schemes are compatible with tree-sitter highlight groups. Color schemes are installed to \~/.local/share/nvim/site/pack/packer/opt/nvcode-color-schemes.vim. If you edit files in that directory, they will be overwritten the next time Packer compiles your plugins. ## Available colorschemes: ``` bash nvcode (basically just dark+) onedark nord aurora (more colorful nord) gruvbox palenight snazzy (Based on hyper-snazzy by Sindre Sorhus) ``` ## Switching colors To switch color schemes on the fly, type the following command: ``` vim :Telescope colorscheme ``` To change the color scheme permanently, modify \~/.config/nvim/lv-settings.lua ``` lua O.colorscheme = 'lunar' ``` # Useful commands for troubleshooting Whether you plan on using LunarVim as is or as a base to configure your own neovim, the following commands may be useful. Any command that includes the symbol ‘:’ is meant to be typed as a command in neovim.
