Autocommands

To set up autocommands use the native nvim api vim.api.nvim_create_autocmd, or use the helper Lunarvim table lvim.autocommands which will be passed to define_autocmds() automatically.

lvim.autocommands = {
    {
        "BufEnter", -- see `:h autocmd-events`
        { -- this table is passed verbatim as `opts` to `nvim_create_autocmd`
            pattern = { "*.json", "*.jsonc" }, -- see `:h autocmd-events`
            command = "setlocal wrap",
        }
    },
}

This will run a command at a given event for the given filetype.

An example using the nvim api could look like this:

vim.api.nvim_create_autocmd("BufEnter", {
      pattern = { "*.json", "*.jsonc" },
      -- enable wrap mode for json files only
      command = "setlocal wrap",
})

You can also add lua callbacks

lvim.autocommands = {
    {
      "BufWinEnter", {
      pattern = { "*.cpp", "*.hpp" },
      callback = function()
        -- DYI editorconfig
        if vim.loop.cwd() == "path/to/my/project" then
          vim.cmd [[setlocal tabstop=8 shiftwidth=8]]
        end
      end
    },
  }
}
