Hi all,
I'm a novice to Clojure (but not to programming).
I'm looking for an implementation of an eval function to eval expression
like Mathematica does.
For instance, in Mathematica the expression:
8 + a + 9 (2 + b) + 2
if a and b are not bound, translates to
Plus[10, a, Times[9, Plus[2, b]]]
if a and b become bounded later (let say to 1 and 2) and the expression
is evaluated again, it returns 47.
I would like to be able to run:
(eval-partial '(+ (+ 8 2) a (* 9 (+ 2 b))))
and get, if a and b are unbound:
(fn [x y] (+ 10 x (* 9 (+ 2 y))))
or (better still)
['(a b) (fn [x y] (+ 10 x (* 9 (+ 2 y))))]
Notice that, whenever possible, the eval takes place and parts of the
expression are evaluated (in the example above, the expression (+ 8 2) is
evaluated to 10).
If you know of any implementation or have any ideas on the subject,
please let me know.
Cheers,
Dilvan.
