Hi @grangerelixx, can you make this more concrete? You aren’t actually posting valid elixir code, which makes this hard to understand.

Of cause you can do that. However, I’d suggest you to finish some elixir tutorial on your own first, otherwise it is hard for other people to offer you help without knowing you have a baseline knowledge.

If you have prior experience with functional programming, the official Elixir tutorial should be enough. If you do not have any experience of functional programming, you can consider to purchase a book or some online tutorial that have more details than the official elixir tutorial.

I will replace “can” with “must”. Otherwise, if you call: function_with_arg3_equals_5(1, 2, 10000) it defeats the purpose of the funtion name, and you should be calling function_1/3

So your question is?

It will help if you can post real code.
My advice is not to create extra functions, just be explicit when you call a function. It will make your code more readable, and lean.

Thank you all for the inputs. I was able to execute what I intended to.

def function_1(arg1,arg2,arg3) do 
  does something
end

def function_with_arg3_equals_5(arg1,arg2,arg3 \\ 5) do
  function_1(arg1,arg2,arg3)
end

def function_with_arg3_equals_10(arg1,arg2,arg3 \\ 10) do
  function_1(arg1,arg2,arg3)
end
