Dear fellow Clojurians,
I'd like to announce a new release of Clojuresque formerly known as
clj-gradle. There not many changes, but some fixes. Namely:
* compileClojure now fails, when compilation fails
* compileClojure does not depend on compileJava anymore. The user can
decide now.
*
At my workplace (University of Houston, dept. of Health and Human
Performance) Clojure is our primary language for interacting with our
virtual world presence in Second Life.
We have an automated lesson path building system currently in
production, and several other projects in various states.
Hi Mike - thanks for this.
I am fairly new to git, but from what I can tell, I have the agraph32

to be using the AG 4.0 API. For example...
You're right, the tests have not been converted to 3.2, so they are not
running at this time. The best thing to look at is the tutorial.clj - most
of these work properly, but example6 doesn't return correct results. The
ones that don't work is where the clj code is incomplete, so I still have
I did take a little bit of a look at it and it is both simple and

When you're not AOT compiling code, the symbol that's creating the

This metadata is then explicitly moved on to the namespace.
