Released Specter 1.0 and wrote a post about why I consider it Clojure's missing piece http://nathanmarz.com/blog/clojures-missing-piece.html

any tips simplifying this path?

sp/ALL
(sp/collect-one sp/FIRST)
sp/LAST

basically MAP-VAL but capturing the key

@wei you can factor it as (def MY-MAP-VALS (comp-paths ALL (collect-one FIRST) LAST))

aha, thanks @nathanmarz

also, if I wanted to run some formatting function on the captured value, how would I express that?

this doesn’t give me what I want:

sp/ALL
(sp/collect-one sp/FIRST some-format-fn)
sp/LAST

@wei do (view some-format-fn)
