Hello everyone,
I have a ref, which is a hashmap of monsters (they key is a unique id, the
value is the monster) like this:
*(defrecord mob [name level hp-cur hp-max])
(def mobs (ref {}))
(defn addmob []
(dosync (alter mobs assoc (gen-id) (->mob "test" 1 2 3)))*
Now if I add 1000 monsters, like this:
*(repeatedly 1000 addmob)*
it will take a few minutes, use a lot of RAM and might even fail if its not
a 64 bit JRE (due to RAM limitations).
As it seems the problem isn't exactly clojure, its the fact that the result
is being shown in the REPL (which is a huge string).
If I modify my addmob function to return nil:
*(defn addmob []
(dosync (alter mobs assoc (gen-id) (->mob "test" 1 2 3))
nil)
*Then *(repeatedly 1000 addmob)* is really fast because it doesn't show the
whole result in the REPL.
*(Please note that the problem has nothing to do with the repeatedly
function. Even if I already have 1000 mobs in my hashmap and then only add
another one, it also takes forever to show the result in the REPL.)*
Does anyone know a elegant solution to my problem, besides writing
something like "alter-silent" that always returns nil instead of the whole
ref? Am I just using things the wrong way? Or could it have something to do
with Eclipse?
Thanks in advance!
