I've been struggling with this for two hours. I want to have a nice
overview of all links at the bottom of my document, so I defined a mutable
hash table and made my link function add an entry to it every time it's
called.
(define references (make-hash))
(define (link url text [class ""])
(hash-set! references text url)
`(a ((href ,url) (target "_blank") (class ,class)) ,text))
My problem now, is how do I actually display this thing?
I've turned the hash table into a list of strings:
from
'#hash(("Blender" . "https://www.blender.org/";)
("Racket" . "http://racket-lang.org/";))
with ◊(hash-map references (lambda (x y) (string-append x ": " y))), to
'("Racket: http://racket-lang.org/";
"Blender: https://www.blender.org/";)
Now I want to feed each element of this list into a tag function, basically
something like
◊(map p (hash-map references (lambda (x y) (string-append x ": " y))))
if it actually works. How do I make this work?
