Re: "Late provide error" in compiling clojurescript files

Thanks for your response Benjamin. I was leaning towards cyclic dependency myself. I couldn't get closurebuilder.py (which apparently detects cyclic dependencies) but couldn't get it to run on my source. After your response, I did a dependency analysis by hand and found no cycles. However, I narrow

Re: Storing clojure lists and maps in Redis

Here's an example of a Ring session store that writes clojure maps to and from Redis: https://github.com/wuzhe/clj-redis-session/blob/master/src/clj_redis_session/core.clj In addition to Deep Freeze, you might check out Kryo, accessible via Alex Miller's Carbonite

Re: Destructuring syntax

I had the same thought when I first started learning Clojure - I think the idea is that there is some nice mental resonance when destructuring matches up to your mental model of the data structure (it's literal form). In sequential destructuring, that holds but in maps it doesn't so things look "b

Re: Storing clojure lists and maps in Redis

read/pr-str works well, but it's painfully slow relative to something like Redis. JSON libraries and the like would be faster, but might require more contortions if you're using lots of Clojure data types. My 2c: the best overall compromise atm is the Deep-Freeze serialization library (https://gith

That does feel a bit more natural, but how would you handle :keys, :as, and :or? On Wed, Jan 4, 2012 at 1:36 AM, Johnny Weng Luu wrote: > One thing that seems weird is the way Clojure destructures a map > > I have this map: {:last-name "Vinge" :first-name "Vernor"} which is passed > to this funct

Destructuring syntax

One thing that seems weird is the way Clojure destructures a map I have this map: {:last-name "Vinge" :first-name "Vernor"} which is passed to this function: (defn greet-author-2 [{fname :first-name}] ... ) Wouldn't it be better doing: (defn greet-author-2 [{:first-name fname}] ... ) You first
