## Lua keymaps

Map a save command

vim.keymap.set("n", "<leader>w", "<cmd>write<CR>")

# Bind a normal-mode key to save the file.

Map Telescope file search

↗#

vim.keymap.set("n", "<leader>ff", function()
  require("telescope.builtin").find_files()
end, { desc = "Find files", silent = true })

# Bind a key to file-finding with a Lua callback.

Map line movement in visual mode

↗#

vim.keymap.set("v", "J", ":m '>+1<CR>gv=gv")
vim.keymap.set("v", "K", ":m '<-2<CR>gv=gv")

# Move selected lines up or down.

## Lua autocommands

Create an autocmd

↗#

vim.api.nvim_create_autocmd("BufWritePost", {
  pattern = "*.lua",
  callback = function()
    print("saved lua file")
  end,
})

# Run code when matching files are written.

Create an augroup

↗#

local grp = vim.api.nvim_create_augroup("MyGroup", { clear = true })

# Group related autocmds together.

Format on save with LSP

↗#

vim.api.nvim_create_autocmd("BufWritePre", {
  pattern = "*.ts",
  callback = function()
    vim.lsp.buf.format()
  end,
