(assoc list key or-val)
Defined at lib/data/alist.lisp:3:2
Return the value given by KEY in the association list LIST, or, in the
case that it does not exist, the value OR-VAL, which can be nil.
Example:
> (assoc '(("foo" 1) ("bar" 2)) "foo" "?")
out = 1
> (assoc '(("foo" 1) ("bar" 2)) "baz" "?")
out = "?"
(assoc->struct list)
Defined at lib/data/alist.lisp:72:2
Convert the association list LIST into a structure. Much like
assoc, in the case there are several values bound to the same key,
the first value is chosen.
Example:
> (assoc->struct '(("a" 1)))
out = {"a" 1}
(assoc? list key)
Defined at lib/data/alist.lisp:22:2
Check that KEY is bound in the association list LIST.
Example:
> (assoc? '(("foo" 1) ("bar" 2)) "foo")
out = true
> (assoc? '(("foo" 1) ("bar" 2)) "baz")
out = false
(extend ls key val)
Defined at lib/data/alist.lisp:48:2
Extend the association list LIST_ by inserting VAL, bound to the key
KEY, overriding any previous value.
Example:
> (extend '(("foo" 1)) "bar" 2)
out = (("bar" 2) ("foo" 1))
(insert alist key val)
Defined at lib/data/alist.lisp:37:2
Extend the association list ALIST by inserting VAL, bound to the key
KEY.
Example:
> (insert '(("foo" 1)) "bar" 2)
out = (("foo" 1) ("bar" 2))
(insert! alist key val)
Defined at lib/data/alist.lisp:59:2
Extend the association list ALIST in place by inserting VAL, bound to
the key KEY.
Example:
> (define x '(("foo" 1)))
> (insert! x "bar" 2)
> x
out = (("foo" 1) ("bar" 2))
(struct->assoc tbl)
Defined at lib/data/alist.lisp:92:2
Convert the structure TBL into an association list. Note that
(eq? x (struct->assoc (assoc->struct x))) is not guaranteed,
because duplicate elements will be removed.
Example
> (struct->assoc { :a 1 })
out = (("a" 1))
