Setting up hash items at once

Postby vetelko » Tue Aug 15, 2017 9:39 am

Hi guys,
is it possible to set hash items at once in hash definition?

Code: Select all
;; this works
(define cities:cities)
(cities "ny" "new york")
(cities "sf" "san francisco")
(println (cities "sf"))

;; this not
(define cities:cities '(
    ("ny" "new york")
    ("sf" "san francisco")))

(println (cities "sf"))

Code: Select all
(define cities:cities)         ; creates the default functor
(cities '(("ny" "new york") ("sf" "san francisco")))        ; the functor adds the data

And you can of course combine it into a single phrase like
Code: Select all
((or (define cities:cities) cities)
  '(("ny" "new york")  ("sf" "san francisco")))
but it's not very intelligible.
