Defining a custom autocommand is very straightforward, it works just like a native one, with the exception of the keyword User, example below:

autocmd User MyCustomEvent call my_custom_function()

And this is how you would trigger it:

doautocmd User MyCustomEvent

At the time of writing this, both augroups and autocommands do not have an interface yet, but it’s being worked on pull request #14661

In the mean time, you can either create autocommands in Vimscript or use this wrapper from norcalli/nvim_utils
