All,
I've been playing with Clojure and found this
website, http://www.lisperati.com/clojure-spels/casting.html. Typed the
code into Clojure 1.4.0 and got the issue below. Here is the code in
question.
(defmacro defspel [& rest] `(defmacro ~@rest))
(defspel game-action [command subj obj place & args]
`(defspel ~command [subject# object#]
`(spel-print (cond (and (= location '~'~place)
(= '~subject# '~'~subj)
(= '~object# '~'~obj)
(have? '~'~subj))
~@'~args
:else '(i cannot ~'~command like that -)))))
(game-action weld chain bucket attic
(cond (and (have? 'bucket) (def chain-welded true))
'(the chain is now securely welded to the bucket -)
:else '(you do not have a bucket -)))
When I do
(weld chain bucket)
instead of getting
(you do not have a chain -)
I get
(i cannot weld like that -)
>From what I'm reading (defspel game-action..., something isn't correct and
the result is the :else instead of the if. This was written using Clojure
1.1, so if anyone has a solution about why this works in 1.1 and not 1.4 I
would like to hear it.
TIA,
Joe
