Idiomatic stage refreshes

I'm trying to get to grips with requesting and caching progressively more detailed information from a data source, and I'd appreciate some pointers on idiomatic ways to achieve this in Clojure. The current implementation is in Angular, and the actual implementation would be in ClojureScript, bu

This is part of the proposed GSoC ClojureScript & Closure project so we're likely to see support for this by sometime this fall. Dvid On Mon, Mar 23, 2015 at 10:42 PM, james borden wrote: > Is there a way to automatically generate externs files for js libraries > for use with the cljs advanced

Use reduce or something appropriate instead of loop / recur

Hi, I wrote a function to trackdown a path in a vector containing nested maps: (defn get-files-from-folder-path [ffs folder-path] (filter #(= :file (:type %)) (loop [tree-path-position 0 acc [] fof ffs] (let [folder (first (filter #(and

Re: Use reduce or something appropriate instead of loop / recur

Separate out traversal from selection to make this clearer. We make a generic traversal function get-in-via. It accepts a via function which takes the current result and some value which determines the next result, and returns the next result. (defn get-in-via [m via ks] (reduce (fn [m' k] (v

Re: Use reduce or something appropriate instead of loop / recur

Notice that get-in-via is simply reduce: (defn get-in-via [m via ks] (reduce (fn [m' k] (via m' k)) m ks)) Same as: (defn get-in-via [m via ks] (reduce via m ks)) Same as: (reduce via m ks) So once you write your "step" function, traversal is taken care of by the reduction. On Tues

Re: Kwargs vs explicit parameter map for APIs?

How come this is so debated, but normal variadic functions are not? Is it only because there's nothing equivalent to apply for kwarg functions? Would it really be such a huge addition to clojure.core to add a simple mapply function, especially given that the core API have kwarg functions? (this

Re: Kwargs vs explicit parameter map for APIs?

I guess with "mapply" using kwarg defined functions in compositional context would be helpful. It would have to be implemented as a method of the function object itself so that the map can be passed directly without any transformation. On Tuesday, March 24, 2015 at 11:03:17 PM UTC+1, Marcus Ma

Clojure Culture Question on TDD

What is TDD culture in Clojure like? Is it strong in the community and other projects? I am aware of Rich Hickey's guard rail analogy. Did that have an effect on how Clojurists view TDD or testing in general? Just asking for my own personal research. -- You received this message because you a

Re: Clojure Culture Question on TDD

It is rare to see an open source clojure project without tests. Clojure itself is pretty thoroughly tested, as is leiningen. I don't know about test-first. I think it's actually more common to see "REPL-first" -- build something through exploration in the REPL and then turn whatever you did in the

Re: Clojure Culture Question on TDD

Guess this is somewhat a personal perspective, but here are some thoughts on testing in Clojure: - People do a lot of automated testing in general and there are some great testing libraries available (e.g. test.check) - People tend not to strictly follow "Test Driven Development" practices. e.g

The reduce in your mapped function is already implemented by get-in. Other possible implementations using get-in: (defn map-in [coll ks f & args] (->> coll (map #(get-in % ks)) (map #(apply f % args Or: (defn map-in [coll ks f & args] (map #(apply f (get-in % ks) args) col
