Hey everyone! This is my first time posting on here, and I’m getting started with writing some real Elixir code! I’m not new to programming, but I also wouldn’t call myself a programmer, more of a hobbyist since I do a lot more with systems and security. Anyhay, I really like to learn coding desig…

10 arguments is pretty unwieldy. What you’ll see more commonly is a data structure defined with defstruct that is used in the module. Maybe a couple of constructors, and then functions that accept other args and implement logic to add to the structure, and then functions that consume it. The other …

Thank you! You’ve given me some stuff to look into. I’ll do some playing around and report back with what I think is the code design you’re talking about :slight_smile: But for starters, you’re saying it’d be like: defmodule MyModule do defstruct arg4: "default1", arg5: "default2" def testfun…

What he’s saying is this: defmodule MyModule do @enforce_keys [:arg1, :arg2, :arg3] defstruct :arg1, :arg2, :arg3, arg4: “default”, arg5: “default” def testfunc(%__MODULE__{} = params) do ... end end You can then access the arguments in the params variable. Enforce keys requires…

Oh interesting, I haven’t come across that syntax yet. I’ll try that out hopefully tonight or tomorrow when I can return to this

If your argument list is always used together, the struct approach can be powerful. If the arguments are more ad-hoc, one approach you’ll see in other languages is named arguments. Elixir doesn’t specifically have named arguments, but you can get close with a keyword list: def some_func(required_a…

Fortunately my optional args are known so in this case the struct will make a lot more sense. The second suggestion you showed me reminds me a lot of what I’ve been doing in Python. And thank you for the link! That really helps too!

What if there are multiple functions which require different inputs?
