Re: defmacro help
then the error is on the (schema.core/defn) call. But notice the fully qualified 'create' - I want 'create' to be a literal in the namespace of the caller, not the namespace the macro is defined in. Any ideas? Quote-unquote the symbol: ~'create Example: `(defn create []) = (clojure.core/defn user/create []) `(defn ~'create []) = (clojure.core/defn create []) -- You received this message because you are subscribed to the Google Groups Clojure group.

[ANN] from-scala 0.2.0: An experimental Scala interop library for Clojure
Hi, I would like to announce from-scala, an experimental Scala interop library for Clojure. Its main feature is the $-macro, a version of Clojure's .-form. The $-macro uses Java reflection and a series of heuristics, so that you will be able to write code like ($ ($ scala.collection.immutable.List/empty) :: 1) instead of the equivalent but ugly (.$colon$colon (.empty scala.collection.immutable.List$/MODULE$) 1) Additionally there are some utility functions for working with case classes, tuples, options, Scala functions, and Scala collections. The source code can be found at https://github.com/t6/from-scala and there are more examples in the guide at https://t6.github.io/from-scala To use from Leiningen: [t6/from-scala 0.2.0] [org.scala-lang/scala-library 2.11.5] You need to provide your own Scala library. from-scala has been tested with Scala 2.10 and 2.11. If you encounter any bugs or road blocks, have a feature request, or want to discuss if this is a good or a bad idea, please open an issue on GitHub.

Re: [Very newbie] invocation of java code.
java.util.TimerTask is an abstract class, which you cannot instantiate directly. You can use proxy to create a subclass: (proxy [java.util.TimerTask] [] (run [] ...)) Instead of (new java.lang.Boolean ...) use true or false directly. There is syntactic sugar for new, just append a dot to the class name: (java.io.File. ...) instead of (new java.io.File ...) -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: clojure/data.json parsing
I hope I understood you correctly. You basically don't want to use
println if you want to print data in such a way that it can be read in
again. For that you need to use pr, prn or pr-str.
Example:
(println {:a hi there}) will print {:a hi there}
(prn {:a hi there}) will print {:a hi there}
(println Ex: (pr-str {:a hi there})) will print Ex: {:a hi there}
In other words I suspect that your example's :paymentStatus is the
string QUEUED already. You can check if a value v is a string with
(string? v).

Re: defrecord inside defmacro
Hi, you need to syntax-quote the list you return from your macro. (defmacro some-record [some-name] `(defrecord ~some-name ['in 'out])) Note the backtick `. You then also have to explicitly quote your record field names (see 'in and 'out, try to remove the quotes to see why).

Re: Does lein midje also run tests written using expectations?
That `lein midje` runs your expectations is just a side effect of expectations' behavior to run its tests on JVM shutdown. Use `(expectations/disable-run-on-shutdown)` to disable that feature. Just need to confirm that the behaviour is intentional and not just by chance. I guess it's a little bit of both ;-) -- You received this message because you are subscribed to the Google Groups Clojure group.

Re: Any Previous Work on Javadoc to Docstring Conversion?
I have just uploaded some code I wrote earlier this year, where I originally set out to generate some useful docstrings for Java classes and methods.

I never finished it, but this may still be useful to you :) Check it out here: https://bitbucket.org/tobik/nrepl-javadoc/src/cdbfe0873ef04ee583a39f0538610daf289eff42/src/tobik/nrepl/tools.clj?at=master#cl-343 -- You received this message because you are subscribed to the Google Groups Clojure group.
