TL;DR: I want to know best practices for designing functions with multiple
optional arguments.
Okay, so I'm working to build machine learning algorithms in Clojure, and
they tend to need many arguments. Being a long-time Ruby dev, I like to
provide sensible defaults for almost all potential
TL;DR: I want to know best practices for designing functions with multiple
optional arguments.
Use destructing:
(defn f [required {:keys [foo bar] :or {foo :default}}]
[required foo bar])
(f 3 :bar 1 :foo 2) ;= [3 2 1]
(f 3 :bar 1) ;= [3 :default 1]

Hi,
you can use destructuring to provide defaults. And you can easily curry in
options when passing things through.
(defn general-descend
[xy ys
{:keys [gradient-fn cost-fn yield-fn alpha iterations thetas]
:or {cost-fncost
yield-fn println
alpha
I'm not sure you read the whole question. I want to know how to delegate
optional arguments to other functions with the same method signatures.

Ah I see, I didn't realize I could apply the general-descend algorithm to
both atoms and arrays to get a flattened list. Thanks!

I think the best is to use maps. It is rarly a good idea to have too many
arguments.

Hello David.
I have a very similar scenario according to named parameters liker you.
Therefore I have written the library clojure.options which can be found
here:
https://github.com/guv/clojure.options
The latest version is also on clojars.
Greetings,
Gunnar
