Trying to understand neovim config madness.

1. init.lua

~/.config/nvim/init.lua

-- load my "pure vim" configs
vim.cmd("source ~/.vimrc")

2. lazy.nvim package manager

Follow the instructions here.

init.lua:

local lazypath = vim.fn.stdpath("data") .. "/lazy/lazy.nvim"
if not vim.loop.fs_stat(lazypath) then
  vim.fn.system({
    "git",
    "clone",
    "--filter=blob:none",
    "https://github.com/folke/lazy.nvim.git",
    "--branch=stable", -- latest stable release
    lazypath,
  })
end
vim.opt.rtp:prepend(lazypath)

local plugins = {}
local opts = {}

require("lazy").setup(plugins, opts)

3. colorscheme

catpuccin for Neovim

init.lua

-- ...
local plugins = {
  { "catppuccin/nvim", name = "catppuccin", priority = 1000 }
}
-- ...

require("catppuccin").setup()
vim.cmd.colorscheme "catppuccin"

4. telescope

nvim-telescope

init.lua

-- ...
local plugins = {
  -- ...
  {
    'nvim-telescope/telescope.nvim', tag = '0.1.5',
    dependencies = { 'nvim-lua/plenary.nvim' }
  }
}
local opts = {}

require("lazy").setup(plugins, opts)

local builtin = require("telescope.builtin")
vim.keymap.set('n', '<C-p>', builtin.find_files, {})
vim.keymap.set('n', '<leader>fg', builtin.live_grep, {})

This sets <C-p> for fuzzy finding and <leader>fg to grep files.

5. treesitter

install instructions (note: the instructions in the wiki are kinda complex)

init.lua

-- ...
local plugins = {
  { "nvim-treesitter/nvim-treesitter", build = ":TSUpdate" }
}

-- ...

local config = require("nvim-treesitter.configs")
config.setup({
  ensure_installed = { "lua", "javascript", "vim", "python" },
  highlight = { enable = true },
  indent = { enable = true }
})

6. neo-tree

quickstart

local plugins = {
  -- ...
  {
      "nvim-neo-tree/neo-tree.nvim",
      branch = "v3.x",
      dependencies = {
        "nvim-lua/plenary.nvim",
        "nvim-tree/nvim-web-devicons", -- not strictly required, but recommended
        "MunifTanjim/nui.nvim",
        -- "3rd/image.nvim", -- Optional image support in preview window: See `# Preview Mode` for more information
      }
  }
}

-- neo-tree keymap
vim.keymap.set('n', '<leader>e', ':Neotree filesystem reveal left<cr>')

7. organizing plugins

From Lazy.nvim's Structuring Your Plugins.

We can do this in our init.lua:

require("lazy").setup("plugins")

And then we create a ~/.config/nvim/lua/plugins/ directory. Inside this directory we can add individual files for each plugin we want to add. This is awesome to keep things organized.

LSP

Install:

lua/plugins/lsp-config.lua:

return {
  -- https://github.com/williamboman/mason.nvim
  {
    "williamboman/mason.nvim",
    config = function()
      require("mason").setup()
    end
  },

  -- https://github.com/williamboman/mason-lspconfig.nvim
  {
    "williamboman/mason-lspconfig.nvim",
    opts = {
      ensure_installed = { "lua_ls" }
    }
  },

  -- https://github.com/neovim/nvim-lspconfig
  {
    "neovim/nvim-lspconfig",
    config = function()
      local lspconfig = require("lspconfig")
      lspconfig.lua_ls.setup({})

      vim.keymap.set('n', 'K', vim.lsp.buf.hover, {})
      vim.keymap.set('n', 'gd', vim.lsp.buf.definition, {})
      vim.keymap.set({ 'n', 'v' }, '<leader>ca', vim.lsp.buf.code_action, {})
    end
  }
}
