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 []) =

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 $-macro uses Java reflection and a series of heuristics, so that you will be able to write code like ($ ($

Yes, you can tag your facts, and then only run the facts with a specific tag. See https://github.com/marick/Midje/wiki/Lein-midje under the :filter section. -- You received this message because you are subscribed to the Google Groups Clojure group. To post to this group, send email to

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

Re: clojure/data.json parsing

2014-09-27 Thread Tobias Kortkamp
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}

Re: defrecord inside defmacro

2014-09-14 Thread Tobias Kortkamp
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). Also

2014-09-08 Thread Tobias Kortkamp
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

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. It currently uses javadoc on all Java source files on the classpath and creates a map with the extracted information. I never finished it, but
