Hi
I want to output some sound with javax.sound.sampled.
But from AudioSystem.getSourceDataLine i get a AbstractDataLine which i
need to typecast to a SourceDataLine. How can i make this typecast in
clojure?
Thanks
Fabian

Hi,
## Basic Question
Is there a library that:
(1) is like slingshot.slingshot and
(2) has the same syntax + semantics in both clj and cljs ?
## Situation I'm stuck in:

that simultaneously work with both clj and
I get a:
java.lang.IllegalArgumentException: Can't call public method of non-public
class: public final void

From a tutorial i saw that they first typecast the
From what i understood cast only checks if a-instance can be a
SourceDataLine. But it doesn't cast the AbstractDataLine to a
SourceDataLine?
Thanks Fabian

Maybe your needs are met by the now builtin ex-info and ex-data. They work
the same in clj and cljs:
(try (throw (ex-info msg {:data map}))
(catch :default e
(ex-data e)))
kind regards

Very nice.
Much better than the past 2 hours I spent writing a simpler version of
Throwable w/ data, i.e.:
(ns MyError
(:gen-class
:extends java.lang.Throwable
:state state
:init init
:constructors {[Object] []}))
(defn -init
[obj]
[[] obj])
Thanks!

I don't have any plans at the moment for that. LibGDX actually does allow
you to compile your game to HTML/JS, but it uses GWT which is a source code
translator, so it only works with Java. Also, it doesn't have access to the
parts of LibGDX that rely on native code, such as the physics engine

Hi,
fn does additional stuff which let doesn't. fn returns an object which you
can store and later call invoke on it. This is more than let promises. From
the implementation point, fn creates java class. This is not needed for let.

I might have missed this in the docs, but is there support for c.j.j's

you can only pass query parameters at this point.

If there's another reason then I'm hoping someone will correct me, but I

Since Clojure doesn't do tail call elimination implementing let atop fn would
also use up stack.
I believe many or all Schemes (which are required by the spec to eliminate

I find that behavior weird and troublesome for those wanting to use the
