Re: clojurescript multimethod error

I can confirm that this patch resolves the issue for me. Thanks! As to whether null and undefined should be interchangeable, I'm not sure what the right answer is. I think that depends on how many times undefined is returned as a result from a cljs function. If it happens pretty often, then we pro

clojurescript multimethod error

I'm getting an error when trying to call a multimethod in a certain scenario. I'm unfortunately not able to reproduce this when running it as a test case with v8. But, I was able to trim it down to the following test case which fails for me in a browser (with a connected repl). (defmulti foo (fn

When I re-read the thread "defrecord with inheritance" https://groups.google.com/forum/?fromgroups#!searchin/clojure/inherit/clojure/mr-o9sRyiZ0/oM4zRz4dXYsJ I am thinking: conceptually, for code reuse, is it a good idea to have protocol specific type hierarchy? I mean something like this: (defr

:auto-refresh in ring apps

Hi, I am developing an app in clojurescript with cljsbuild doing the compiling. ring has a configuration option where if :auto-refersh? is set to true in the project.clj, then browser will be refreshed when any resource files are changed. This will be ideal, as any generated clojurescript fi

Re: Problems With BigDecimal Precision

Hi Eric, I tried to see what was going on with this calculation, knowing that when working with Java libraries which takes primitive type (as it is the cas with Math.pow) this can be easily corrupted, which is the case in the * probability-collision* fn So , I think that Java lib cant be used.

Re: Protocol as an abstract data type

IIndexed is the protocol that maps to nth. Well, IIndexed is the protocol behind -nth, and some dispatching also happens in nth itself. So there is two levels of dispatch: in the nth function (closed) and in the IIndexed protocol (open). See the Michał Marczyk's comment about IIndexable and

Hi all, A little exercise to get me started with clojurescript turned into something people might actually find useful: dyscord, a clojurescript library to bring emacs-like key sequences to web-apps. usage = A key sequence, is a sequence of keyboard key presses. Any element in such a sequenc

Re: 64 or 32 bit eclipse

Clojure should not have any sensitivity to the underlying CPU architecture. Based on the stack trace, it looks like either some REPL expression or file in a project you're working on is attempting to load a library namespace, but is failing…probably due to not having the right dependencies on th

Re: 'last' on empty collections

This decision definitely is a part of clojure design; as far as I can tell, clojure tends to not throw an exception unless the input is terribly wrong (e.g. can't be converted to a seq in your case). Of course, it has some drawbacks, but is pretty convenient for the programmer and doesn't cause

Re: Repeatedly asking for user input i.e. calling (read-line) hangs?

Hi, you wait for five lines. So you have to enter five lines. Enter three more and the "hung" will go away. If you want to read an arbitrary number of lines and bail out depending on some decision you may use a lazy sequence. (loop [lines (repeatedly read-line)] (let [line (first lines)]
