Is this possible in Specter?

Question

philoskim opened this issue 5 years ago · comments

I want to change the data structure [:a :b :c [1 2 3 4]] into [:a :b :c 1 3 [2 4]] by using Specter library.

In other words, what I want is to move only the odd numbers of the nested vector to the outer vector.

I cannot find the way and I wonder it can be achieved by using Specter.

If it is impossible, I hope that this feature could be added to the future version of Specter.

Yes, it's possible:

(transform (subselect (multi-path (srange 3 3) [LAST ALL odd?]))
  (fn [res] [(rest res)])
  data)
