Hi. I'm a newbie so bare with me. I have just started playing with Clojure and the first thing I thought I'd try is storing and retrieving a seq of structs, like in Suart Halloway's example here:
http://github.com/stuarthalloway/practical-cl-clojure/blob/1c2f138bda5e73ebbbafbc2cea7e5cd14ec335c4/pcl/chap_03/chap_03.clj My spit/slurp of a hash of structs works fine with, if I use struct instances without spaces in the attribute strings like the following: (struct customer "Apple" "InfiniteLoop") But if I use this: (struct customer "Apple" "Infinite Loop 1") I get an error: Exception in thread "main" clojure.lang.LispReader$ReaderException: java.lang.ArrayIndexOutOfBoundsException: 7 (test-storing.clj:19) at clojure.lang.Compiler$InvokeExpr.eval(Compiler.java:2719) at clojure.lang.Compiler$DefExpr.eval(Compiler.java:298) at clojure.lang.Compiler.eval(Compiler.java:4537) at clojure.lang.Compiler.load(Compiler.java:4857) at clojure.lang.Compiler.loadFile(Compiler.java:4824) at clojure.main$load_script__5833.invoke(main.clj:206) at clojure.main$init_opt__5836.invoke(main.clj:211) at clojure.main$initialize__5846.invoke(main.clj:239) at clojure.main$null_opt__5868.invoke(main.clj:264) at clojure.main$legacy_script__5883.invoke(main.clj:295) at clojure.lang.Var.invoke(Var.java:346) at clojure.main.legacy_script(main.java:34) at clojure.lang.Script.main(Script.java:20) Caused by: clojure.lang.LispReader$ReaderException: java.lang.ArrayIndexOutOfBoundsException: 7 at clojure.lang.LispReader.read(LispReader.java:180) at clojure.core$read__4168.invoke(core.clj:2083) at clojure.core$read__4168.invoke(core.clj:2081) at clojure.core$read__4168.invoke(core.clj:2079) at clojure.core$read__4168.invoke(core.clj:2077) at chap_03$load_db__54.invoke(chap_03.clj:71) at clojure.lang.AFn.applyToHelper(AFn.java:173) at clojure.lang.AFn.applyTo(AFn.java:164) at clojure.lang.Compiler$InvokeExpr.eval(Compiler.java:2714) ... 12 more Caused by: java.lang.ArrayIndexOutOfBoundsException: 7 at clojure.lang.PersistentArrayMap$Seq.first(PersistentArrayMap.java: 216) at clojure.lang.APersistentMap.hashCode(APersistentMap.java:101) at clojure.lang.Util.hash(Util.java:55) at clojure.lang.PersistentHashMap.entryAt(PersistentHashMap.java:134) at clojure.lang.PersistentHashMap.containsKey(PersistentHashMap.java: 130) at clojure.lang.APersistentSet.contains(APersistentSet.java:33) at clojure.lang.PersistentHashSet.cons(PersistentHashSet.java:59) at clojure.lang.PersistentHashSet.create(PersistentHashSet.java:34) at clojure.lang.LispReader$SetReader.invoke(LispReader.java:974) at clojure.lang.LispReader$DispatchReader.invoke(LispReader.java:540) at clojure.lang.LispReader.read(LispReader.java:145) ... 20 more I use a store-function like this: (defn store-customer-db [customer-db filename] (spit filename (with-out-str (print customer-db)))) And a read-function like this: (defn load-db [filename] (with-in-str (slurp filename)(read))) >From the output file of spit I can see that the print doesn't give double quotes to the strings which seems to be a problem for slurp. What would be the correct solution for this? My Clojure version is 1.0, and the contrib is a few weeks old snapshot.
