How is main function in 'erlang_ls' called?

[mdbergmann]

Hello.

I'm still a bit new to Erlang. So, sorry for this of topic question.
In my 'release' app I'd also want to allow to pass in command line parameters.
So I'm wondering how in erlang_ls.erl the main function is actually called, what is the wiring that is required for this to work?
I couldn't find anything in erlang_ls that I don't have, but then, it must be something.

Thanks,
Manfred

Erlang LS uses the "escript" feature to generate the executable - this includes calling the main function as the entry-point to the program.

You can learn more here: https://www.erlang.org/doc/man/escript.html and here: https://rebar3.org/docs/commands/#escriptize
