barryCrunch / LunarVim

An IDE layer for Neovim with sane defaults. Completely free and community driven.

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.

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:

-- O is the global options object

-- THESE ARE EXAMPLE CONFIGS FEEL FREE TO CHANGE TO WHATEVER YOU WANT
-- general
-- O.format_on_save = false -- to disbale formatting on save
-- O.lint_on_save = false -- to disable formatting on save
O.completion.autocomplete = true
O.default_options.relativenumber = true
O.colorscheme = 'spacegray'
O.default_options.timeoutlen = 100

-- keymappings 
O.keys.leader_key = "space"
-- overwrite the key-mappings provided by LunarVim for any mode, or leave it empty to keep them
O.keys.normal_mode = {
    -- Page down/up
  {'[d', '<PageUp>'},
  {']d', '<PageDown>'},
}
-- if you just want to augment the existing ones then use the utility function
require("lv-utils").add_keymap_insert_mode({ silent = true }, {
  { "<C-s>", ":w<cr>" },
  { "<C-c>", "<ESC>" }
})

-- you can also use the native vim way directly
vim.api.nvim_set_keymap("i", "<C-Space>", "compe#complete()", { noremap = true, silent = true, expr = true })

-- After changing plugin config it is recommended to run :PackerCompile
O.plugin.dashboard.active = true
O.plugin.terminal.active = true
O.plugin.zen.active = true

-- if you don't want all the parsers change this to a table of the ones you want
O.treesitter.ensure_installed = "all"
O.treesitter.ignore_install = {"haskell"}
O.treesitter.highlight.enabled = true

-- you can set a custom on_attach function that will be used for all the language servers
-- See <https://github.com/neovim/nvim-lspconfig#keybindings-and-completion>
-- O.lsp.on_attach_callback = function(client, bufnr)
--   local function buf_set_option(...)
--     vim.api.nvim_buf_set_option(bufnr, ...)
--   end
--   --Enable completion triggered by <c-x><c-o>
--   buf_set_option("omnifunc", "v:lua.vim.lsp.omnifunc")
-- end

-- lua
O.lang.lua.autoformat = false
O.lang.lua.formatter = 'lua-format'

-- javascript
O.lang.tsserver.formatter = 'prettier'
O.lang.tsserver.linter = nil
O.lang.tsserver.autoformat = true

-- python
O.lang.python.diagnostics.virtual_text = true
O.lang.python.analysis.use_library_code_types = true
-- to change default formatter from yapf to black
-- O.lang.python.formatter.exe = "black"
-- O.lang.python.formatter.args = {"-"}
-- To change enabled linters
-- https://github.com/mfussenegger/nvim-lint#available-linters
-- O.lang.python.linters = { "flake8", "pylint", "mypy", ... }

-- go
-- to change default formatter from gofmt to goimports
-- O.lang.formatter.go.exe = "goimports"

-- Additional Plugins
-- O.user_plugins = {
--   {"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)
-- O.user_autocommands = {{ "BufWinEnter", "*", "echo \"hi again\""}}

-- Additional Leader bindings for WhichKey
-- O.user_which_key = {
--   A = {
--     name = "+Custom Leader Keys",
--     a = { "<cmd>echo 'first custom command'<cr>", "Description for a" },
--     b = { "<cmd>echo 'second custom command'<cr>", "Description for b" },
--   },
-- }

-- To link your init.vim (until you find Lua replacements)
-- vim.cmd('source ' .. CONFIG_PATH .. '/lua/lv-user/init.vim')

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 && 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
