raspberry pi and clojure

Hi everyone, I just started trying to play with a raspberry pi for a variety of reasons, and given that java runs on it, I decided to use this as an opportunity to learn clojure. I'm playing with a blinkIo example which looks like this: public class BlinkGpioExample { public static void ma

Functions in data structures?

Is there anything wrong with doing something like this? (def foo (atom {:fn inc})) ((:fn @foo) 1) ; => 2 This works in Clojure and ClojureScript. Just wondering if placing functions into immutable data structures could cause any grief. Or are functions sufficiently “first class” so that this

Re: How to unit test (defn-) functions?

There are 6 defn-'s in there? Rich must have wrote that code :-P . But yes, defn- is mostly used in clojure.core and other such libraries for functions that are created to simplify other functions. And I would probably never test those. Even then I would caution about using defn- too much as some

Hey Timothy So I honestly don't mean to be a smart ass, but there are 6 defn- functions in clojure.core.async - how do you test those? Or are they just considered internals to other public functions? cheers, J On Thu, Jun 12, 2014 at 10:33 AM, Timothy Baldridge wrote: > I say this too many ti

I say this too many times on this list, but I'll say it again. The best way to test defn- functions is to never use defn- in the first place. Instead move implementation functions into an internal namespace that way they can be accessed if needed, but are out of the way of the public api. It also m
