Hi guys, Does anyone know how to properly deal with refs in core.typed? I
am running into trouble. When I try to do stuff like this:
(ann my-ref (Ref1 (U Kw nil)))
> (def my-ref (ref #{}))
I get this error:
> IllegalArgumentException No value supplied for key: true
> clojure.lang.PersistentHashMap.create (PersistentHashMap.java:77)
the only thing I can do to make it work is ^:no-check it, but is this the
solution?
Furthermore, when check this code here:
(defn update-refs [ref-name :- (Ref1 (Set (Option Kw))), update-map :-
> (Map Kw String)] :- (Set (Option Kw))
> (dosync
> (alter some-other-ref merge update-map)
> (alter ref-name s/union #{(first (keys update-map))})))
I get errors about how alter is unable to be applied to its arguments and
how first is a polymorphic function. Here they are in all their glory. I
can't follow the the thread of what exactly is wrong here from what it says.
Type Error (tic_tac_toe/check.clj:80:3) Polymorphic function alter could
not be applied to arguments:
Polymorphic Variables:
w
r
b
Domains:
(Ref2 w r) [r b ... b -> w] b ... b
Arguments:
(Ref1 (HMap :mandatory {:a2 (Option Str), :b2 (Option Str), :c3 (Option
Str), :a3 (Option Str), :a1 (Option Str), :b1 (Option Str), :c2 (Option
Str), :c1 (Option Str), :b3 (Option Str)})) (All [k v] (IFn [nil * -> nil]
[(clojure.lang.IPersistentMap k v) (clojure.lang.IPersistentMap k v) * ->
(clojure.lang.IPersistentMap k v)] [(Option (clojure.lang.IPersistentMap k
v)) * -> (Option (clojure.lang.IPersistentMap k v))])) (Map Kw
java.lang.String)

Type Error (tic_tac_toe/check.clj:79:3) Polymorphic static method
clojure.lang.LockingTransaction/runInTransaction could not be applied to
arguments:
Polymorphic Variables:

Domains:

Arguments:
[-> Any]
Ranges:
x
with expected type:
(Set (Option Kw))
in: (clojure.lang.LockingTransaction/runInTransaction (fn* ([] (do (alter
some-other-ref merge update-map) (alter my-ref s/union #{(first (keys
update-map))})))))
in: (clojure.lang.LockingTransaction/runInTransaction (fn* ([] (do # #))))
Lastly, the example from the wiki with the atom:
(cf (atom {}) (Atom1 (Map Sym Num)))
=> (Atom2 (IPersistentMap Sym Num) (IPersistentMap Sym Num))
does not translate to the ref:
(cf (ref #{}) (Ref1 (Seq (U nil Kw))))
=> IllegalArgumentException No value supplied for key: true
> clojure.lang.PersistentHashMap.create (PersistentHashMap.java:77)
(same error as above)
I have seen this error before on a jira issue posted
here: http://dev.clojure.org/jira/browse/CLJ-1149
What is going on? I am using clojure 1.7.0-alpha4 and core.typed 0.2.72
