Tips

Pretty Print

Use vim.pretty_print() to print things in human-readable format.

:lua vim.pretty_print(vim.loop.cpu_info())

Neovim#22562: pretty_print has been renamed to print.

Use = shorthand version for brevity.

:lua =vim.loop.cpu_info()

Simplify keymaps

-- Modes
--   normal_mode = "n",
--   insert_mode = "i",
--   visual_mode = "v",
--   visual_block_mode = "x",
--   term_mode = "t",

-- Keymaps
local opts = { noremap = true, silent = true }
local keymap = vim.api.nvim_set_keymap

-- Insert --
-- Make Control+Backspace delete whole words
keymap("i", "<C-H>", "<C-W>", opts)

Centering the screen

-- Half-page up/down
keymap("n", "<C-u>", "<C-u>zz", opts)
keymap("n", "<C-d>", "<C-d>zz", opts)

-- Cursor history
keymap("n", "<C-o>", "<C-o>zz", opts)
keymap("n", "<C-i>", "<C-i>zz", opts)

Keep cursor in place

keymap("n", "J", "mzJ`z", opts)
keymap("n", "gJ", "mzgJ`z", opts)

Repeat last macro

Bind , to @@ to repeat last macro with a single key.

keymap("n", ",", "@@", opts)
