Re: more minimal clojurescript intro/app

Thanks Colin -- that does look very cool, and I think I will indeed find it very useful if this limitation is overcome: "Requiring custom clojure[script] libraries in a klipse snippet is not yet available." If I understand correctly, this means that you can't yet use it to provide interactions

Re: why is it so annoying to run clojure code

You did not want to make then depend on Lein, which is… a script, so you wrote your own script and made users of your library depend on it. What's the difference? On Sun, Jun 12, 2016 at 2:36 AM, Antonin Hildebrand < antonin.hildebr...@gmail.com> wrote: > I wanted users of my library (which has d

Re: Bug (in Clojure 1.5): (fn [& xs] (pop xs)) throws ClassCastException clojure.lang.ArraySeq cannot be cast to clojure.lang.IPersistentStack

Currently only vectors and lists implement the stack interfaces, not seqs. I do not think it makes sense for *all* seqs to implement the stack interface. It may not even make sense for any seqs to implement it, but I'd have to think about think about that for a while. Feel free to file an enhan

Re: Qualified keys, Clojure records, Spec

This is a good question and one we've discussed a bit. You can use the existing s/keys with :req-un and :opt-un to spec the (unqualified) keys of a record - there's an example of this in the guide at http://clojure.org/guides/spec. So that's the short-term current answer. However, there are pot

Qualified keys, Clojure records, Spec

I know that Spec and the changes coming to Clojure 1.9 I see that namespace qualified keys have gained some focus. I understand the motivations for this and support it.  The one barrier that is coming up for me is in the use of Clojure records (and perhaps deftype types too). We use records fai

Re: Having trouble doing what I want using macros, is there a better way?

These functions (as-transducer, transducing) are still completely agnostic about the type of the accumulator and result as long as the function you give them only touches result in the following ways: 1. Return result unchanged 2. Return (xf (xf result X) Y), I.e. Whatever you get from applying
