core.typed questions

Hi guys, Does anyone know how to properly deal with refs in core.typed? I am running into trouble. When I try to do stuff like this: (ann my-ref (Ref1 (U Kw nil))) > (def my-ref (ref #{})) I get this error: > IllegalArgumentException No value supplied for key: true > clojure.lang.Persistent

Thanks Di Xu. Good to know. I have joined the core.typed group and will post my questions there from now on. J On Friday, December 12, 2014 11:41:43 PM UTC-6, Jesse wrote: > > Hi guys, Does anyone know how to properly deal with refs in core.typed? I > am running into trouble. When I

Re: How should I implement an elevator state-machine with loops and core.async?

am updating the gist now, and will also add the stack-trace in a comment underneath it. I think the problem is coming when, during the move function execution, the atom gets updated and subsequently re-calls the *move-elevator* function, again and again with each update, making a smorgasbo

I have got in a shape where it works fine, but with slightly unusual behavior. I am looking for advice on refactoring, So if someone could please have a look. https://gist.github.com/gamma235/4ea0d7a0d0efb8d4399f Jesse On Thursday, May 22, 2014 8:25:39 PM UTC+9, Rob Day wrote: >

It would be nice if someone updated the wiki with a new example. I don't understand how the gen-class stuff is supposed to work. Why doesn't the following work? (gen-class :name MyException :extends [Exception]) (defn user-exception-test [] (try (throw (new MyException "msg: user excepti

Wiki -> Concepts -> Libraries -> clojure/ns

Here in the wiki: http://en.wikibooks.org/wiki/Clojure_Programming/Concepts#Libraries The examples make use of the clojure/ns command, for example: (clojure/ns example.ourlib) I had to get rid of the "clojure/" part to make it work. Is the wiki wrong? If so, could somebody update it? --~--~

The wiki

I notice the front page of the wiki has had some changes awaiting review: http://en.wikibooks.org/wiki/Clojure_Programming Apparently they've been waiting for almost a month now? I also noticed this comment on the discussion page: "The approved revision mechanism is killing this wiki. I'm avoid

How to port a mixin to clojure

I'm trying to re-implement some python stuff in clojure. Here's how it works: I have a class called ArrowKeySelection. I use this class as a mixin with various gui classes. The class adds some abstract logic for handling keys - the arrow keys move a selector around a matrix and the enter key

How do I do this in clojure?

I'm trying to port some Python code to Clojure. I'm new to functional programming and I hit a function that is causing my brain to melt. The python function looks something like this: def build_table(): num_cols = 3 selected_row = 0 selected_col = 0 strings = ["cat", "dog", "",
