Following the book, I am confused how to implement mod: in mix.exs as entry point.
Elixir 1.5.0 version deploys lib/sequence/application.ex contained start().
lib/ - sequence.ex
- sequence/ - application.ex
So I set in mix.exs:
def application do
[ mod: {Sequence.Application, []} ]
end
This starts at the application.ex start().
Why do we have lib/sequence.ex like as main application and how to use this file?
Before elixir 1.4 or 1.5 the application start/2 callback was in lib/sequence.ex by default, not lib/sequence/application.ex. lib/sequence.ex is now usually used as a single public interface to other modules in lib/sequence/.
Thank you for a reply.
I understood lib/sequence.ex is not used as the entry point and it seems to use common interface as Ruby structure.
However, it is a little bit difficult for me to read code from the start point step by step.
I think Ruby is OK as OOP, although it is why I can’t be familiar with it. lib/sequence.ex is meaningless as it works without this. Maybe I am not at enough level to see the useful point on this.
