LunarVim/README.md

Install In One Command!

Make sure you have the newest version of Neovim (0.5).

bash <(curl -s https://raw.githubusercontent.com/ChristianChiarulli/lunarvim/master/utils/installer/install.sh)

Installing

The following command installs LunarVim. Change LVBRANCH to the branch you'd like to install. master for the stable branch and rolling for the latest changes.

LVBRANCH=rolling bash <(curl -s https://raw.githubusercontent.com/ChristianChiarulli/lunarvim/rolling/utils/installer/install.sh)

BREAKING CHANGE on the rolling branch

• The latest changes to LunarVim require you to remove it completely before upgrading
• Going forward LunarVim will no longer reside in the nvim configuration folder. LunarVim has been moved to ~/.local/share/lunarvim.
  
• To launch Lunarvim use the new lvim command. nvim will only launch standard neovim.
  
• Your personal configuration file (lv-config.lua) can now be found in ~/.config/lvim. You can initialize this folder as a git repository to track changes to your configuration files.
• If you want to keep launching LunarVim with the nvim command, add an alias entry to your shell's config file: alias nvim=lvim. To temporarily revert to the default nvim prefix it with a backslash \nvim.
• Many options formerly available in lv-config.lua have been renamed. For details look here

Fixing installation problems

If your installation is stuck on Ok to remove? [y/N], it means there are some leftovers, \ you can run the script with --overwrite but be warned this will remove the following folders:

• ~/.cache/nvim
• ~/.config/nvim #Removed only on Master Branch
• ~/.local/share/nvim/site/pack/packer #Removed only on Master Branch
• ~/.local/share/lunarvim #Removed only on Rolling Branch

• ~/.config/lvim #Removed only on Rolling Branch

  curl -s https://raw.githubusercontent.com/ChristianChiarulli/lunarvim/rolling/utils/installer/install.sh | LVBRANCH=rolling bash -s -- --overwrite
  

  then run nvim and wait for treesitter to finish the installation

  Installing LSP for your language

  Just enter :LspInstall followed by <TAB> to see your options

  NOTE I recommend installing lua for autocomplete in lv-config.lua

  For the julia language server look here

  Configuration file

  To activate other plugins and language features use the lv-config.lua file provided in the nvim folder (~/.config/nvim/lv-config.lua) in the master branch or (~/.config/lvim/lv-config.lua) on rolling

  Example:

  -- general
  lvim.format_on_save = true
  lvim.lint_on_save = true
  lvim.colorscheme = "spacegray"
  
  lvim.builtin.compe.autocomplete = true
  
  -- keymappings
  lvim.leader = "space"
  
  -- After changing plugin config exit and reopen LunarVim, Run :PackerInstall :PackerCompile
  lvim.builtin.dashboard.active = true
  lvim.builtin.terminal.active = true
  
  -- if you don't want all the parsers change this to a table of the ones you want
  lvim.builtin.treesitter.ensure_installed = "maintained"
  lvim.builtin.treesitter.ignore_install = { "haskell" }
  lvim.builtin.treesitter.highlight.enabled = true
  
  lvim.lang.python.formatter.exe = "black"
  lvim.lang.python.linters = ""
  
  lvim.lsp.diagnostics.virtual_text = false
  
  -- Additional Plugins
  lvim.plugins = {
  {"lunarvim/colorschemes"},
  {"folke/tokyonight.nvim"}, {
      "ray-x/lsp_signature.nvim",
      config = function() require"lsp_signature".on_attach() end,
      event = "InsertEnter"
  }
  }
  
  -- Autocommands (https://neovim.io/doc/user/autocmd.html)
  -- lvim.autocommands.custom_groups = {
  --   { "BufWinEnter", "*.lua", "setlocal ts=8 sw=8" },
  -- }
  
  

In case you want to see all the settings inside LunarVim, run the following:

cd /tmp
lvim --headless +'lua require("lv-utils").generate_settings()' +qa && sort -o lv-settings.lua{,}

and then inspect /tmp/lv-settings.lua file

Updating LunarVim

In order to update you should be aware of three things Plugins, LunarVim and Neovim

To update plugins:

:PackerUpdate

To update LunarVim:

# Master Branch
cd ~/.config/nvim && git pull
:PackerSync  

# Rolling Branch
cd ~/.local/share/lunarvim/lvim && git pull
:PackerSync

To update Neovim use your package manager or compile from source

Project Goals

1. Provide basic functionalities required from an IDE
   • LSP
   • Formatting/Linting
   • Debugging
   • Treesitter
   • Colorschemes
2. Be as fast and lean as possible
   • Lazy loading
   • Not a single extra plugin
   • User configurable lang/feature enable/disable
3. Provide a simple and easy way for users to share their own configuration or use others.
4. Hot reload of configurations
   • Hot install of lsp/treesitter/formatter required upon openning a filetype for the first time
5. Provide a stable & maintainable error free configuration layer over neovim
   • With the help of the community behind it
   • Github workflow testing
   • Freezing plugin versions
6. Provide detailed documentation
   • Video series on how to configure LunarVim as an IDE for each lang

• @juanCortelezzi, LunarVim user.

"My minimal config with a good amount less code than LunarVim loads 40ms slower. Time to switch."
