I'm having some trouble with java constants in a case statement. I know I
could use condp, but these are things I could put in a java switch
statement and so it's annoying to give up constant time dispatch:
(case (.getActionMasked event)
MotionEvent/ACTION_POINTER_DOWN :down
MotionEvent/ACTI
I'm not 100% sure if this works, but have you tried writing a macro that
gets the
Java field value, and inserting into the case statement?
(defmacro motion-case [...]
`(case ..
~MotionEvent/ACTION_POINTER_DOWN ...
~ MotionEvent/ACTION_UP ...
))

IMO that would needlessly complicate an otherwise simple construct,
especially since a simple macro can endlessly customise it.
Thanks,

That works perfectly, thanks!
It does feel like it should just work as a normal case statement though,
where the value is static final, and warn if it isn't. Is there a good
reason this shouldn't be supported by the case statement that anyone can
think of? Worth filing an enhancement request on cl

That's a neat trick! Didn't know case could do this.
Wouldn't it be great to menti

Oops, I already filed http://dev.clojure.org/jira/browse/CLJ-1367. Should
probably link/mark as dupe - I don't appear to be able to do anything other
than comment.

Oh sorry, I should have looked at the newest issues first.
I don't think the tickets are dupes, because yours calls for enabling java
static fields for case constants.
Mine just wants to add language stating how case can be used right now.
IMO enabling case constants is at odds with current doc l
