nvim

Lua script

An arbitrary vim command can be executed with

vim.cmd('echo 17+25')

vim.fn can be used to call vim functions:

vim.print( vim.fn.printf('x = %d', 42) )

I believe the following Lua expression performs the same as the vim :inoremap jj <esc>:w<cr> (but comare with vim.keymap.set(…)).

vim.api.nvim_set_keymap('i', 'jj', '<esc>:w<cr>', {noremap=true})

Variables

Variables can be accessed like so:

`vim.g`	Global variables
`vim.b`	Current buffer
`vim.w`	Current window
`vim.t`	Current tab-page
`vim.v`	Predefined vim variable
`vim.env`	Environment variable

Options

	Like
`vim.opt`	`:set`
`vim.opt_global`	`:setglobal`
`vim.opt_local`	`:setlocal`

Multiple («map like») values can be assigned like so

vim.opt.wildignore    = { '*.o', '*.a', '__pycache__' }
vim.opt.listchars     = { space = '_', tab = '>~' }
vim.opt.formatoptions = { n = true, j = true, t = true }

TODO: Compare vim.print(vim.o.smarttab) and vim.print(vim.opt.smarttab).

TODO

ctrl-q starts visual block selection. Thus ctrl-v can still be used for pasting text.
