matthiasx86 / lunarvim

An IDE layer for Neovim with sane defaults.

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)

If you help to develop Lunarvim, you can install a specific branch branch directly

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

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 folder:

• ~/.config/nvim
• ~/.cache/nvim
• ~/.local/share/nvim/site/pack/packer

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

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

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)

Example:

-- O is the global options object

-- THESE ARE EXAMPLE CONFIGS FEEL FREE TO CHANGE TO WHATEVER YOU WANT
-- general
-- O.default_options.wrap = true -- wrap long lines
O.completion.autocomplete = true
O.default_options.relativenumber = true
O.colorscheme = 'spacegray'
O.default_options.timeoutlen = 100
O.leader_key = ' '

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

-- 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.isort = true
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 = {"-"}

-- 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')

Updating LunarVim

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

To update plugins:

:PackerUpdate

To update LunarVim:

cd ~/.config/nvim && git pull

To update Neovim use your package manager

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
