Is there a way in meander to not add a matched value to the result if it's nil?

IIRC m/some also works on rhs

How would that look like if I'm matching {:x ?x :y ?y} and want to rewrite as {:x ?x :y ?y} if ?y is some and {:x ?x} if not?

when I'm at the computer later, I'll take a look

@ben.sless

(me/rewrite {:a 1 :b 2 :c 3}
  {:a ?a :d ?d}
  {& [[:aa ?a] ~(if ?d [:dd ?d])]})

unfortunately m/some does not work on rhs

and even worse, I am getting old because my memory is failing ; P

GOT IT

(m/rewrite {:a 'a :b nil}
  {:a ?a :b ?b} {:a ?a & ~@(if ?b [[:b ?b]])})

Feels evil

will do it anyway

Even better:

(m/rewrite {:a 'a :b nil :c 3}

  {:a ?a :b ?b :c ?c}
  {:a ?a
   & ~[(if ?b [:b ?b])
       (if ?c [:c ?c])]})

Thanks borkdude, we now have a starting point
