An autocommand is a command that is executed automatically in response to some event, such as a file being read or written or a buffer change (documentation ).
Start git commit messages in insert mode
vim.api.nvim_create_augroup("bufcheck", { clear = true })
vim.api.nvim_create_autocmd("FileType", {
group = "bufcheck",
pattern = { "gitcommit", "gitrebase" },
command = "startinsert | 1",
})
Enable spell checker on certain files
vim.api.nvim_create_autocmd(
{ "BufRead", "BufNewFile" },
{ pattern = { "*.txt", "*.md", "*.tex" }, command = "setlocal spell" }
)
Set timer to write all buffers every second
local function write_buf_timer()
vim.fn.timer_start(1000, function()
vim.api.nvim_command('wall')
end)
end
vim.api.nvim_create_autocmd({ "VimEnter" }, { callback = write_buf_timer })
