morning

Bon jour

a small question of style for you... when I see the update-last from @otfrom I can grok the if and the else cos it's a snappy bit of code

(defn update-last [v f & args]
    (if (seq v)
      (conj
       (pop v)
       (apply f (peek v) args))
      v))

(defn update-last [v f & args]
  (cond
    (seq v) (conj
              (pop v)
              (apply f (peek v) args))
    :else v))

(defn update-last [v f & args]
  (if-not (seq v)
    v
    (conj
      (pop v)
      (apply f (peek v) args))))

Maybe (if (empty? v)....

I also like to put the easy flow at the beginning

Morning

Agree with the easy flow at the beggining, and with using cond when things become hairy.

for me if either leg of the if became too long I'd prefer to factor it into another funciton and keep the if short

and only use cond if there are more than 2 choices

1 or nil -> when

2 -> if

more than 2 -> cond

complex and more than 2, then possibly core.match or multimethods

I quite like multimethods for quite complex things, it makes each path quite clear

nice rules of thumb so :thumbsup::skin-tone-3:

I usually write out the function all in one and then factor out the legs. Testing in a rich comment block as I go

I, too, love multimethods but they get in my way so easily with code reload, or when abused as a “plugin system”.

Maybe it’s just bad coding habits on my side. I like cond and potentially calling individually named functions which help understanding what’s going on

@ordnungswidrig yeah, I find that too. I usually do them b/c I know things are going to have complicated bodies or refactring a cond

individually named functions are good. multimethods means that I can worry slightly less about names

I've never really taken much advantage of them being open before, but I have worked with libraries that do like dali

Kaocha leverages them for plugins and that works quite nicely

we use them for mapping protocol messages so yeah, the openness is a delight

Goodnight
