I'm not familiar with what source <afile> does. If I remember correctly I tried to find the equivalent in the lua api and there was nothing equivalent (but maybe I remember that wrong). I have the lua code in my init.lua as I wrote in this PR and it works.

There is -- Lua callbacks get passed an args table, with args.file being equivalent to <afile>.

See :h nvim_create_autocmd().

augroup end
local group = vim.api.nvim_create_augroup("packer_user_config", { clear = true })
vim.api.nvim_create_autocmd("BufWritePost", {
command = "PackerCompile",
pattern = "plugins.lua",
group = group,
})
```

This autocommand can be placed in your `init.vim`, or any other startup file as per your setup.
Placing this in `plugins.lua` could look like this:

```lua
vim.cmd([[
augroup packer_user_config
autocmd!
autocmd BufWritePost plugins.lua source <afile> | PackerCompile
augroup end
]])
```
This autocommand can be placed in your `plugins.lua`, or any other Lua startup file as per your setup.
