Dear Clojure Group,
Following an Enlive tutorial I wanted to implement a function 'd-map'
that takes an arbitrary number of [:key (list of values)] parameters
like this:
(d-map [:headline [this is me] ]
[:points [1 2 3] ]
[:comments [10 20 30] ])
and returns a

Try something like this:
(defn dmap [ args]
(for [[head items] args]
item in items]
[head item]))

Your manual composition of concat and map is the same as the built-in
function mapcat.
Anyway, all this is what (for ...) does for you under the covers.

Hello,
All in all, you only used in your first definition core clojure
constructs, you avoided doing imperative in clojure clothes. So, while not
leveraging to its full extent the power of clojure standard library
functions and higher-order-functions, your code certainly qualifies as
functional

Thats what I came up with this.
(defn getpairs [[key coll]] ;; split the key form the data (http://
blog.jayfields.com/2010/07/clojure-destructuring.html)
(map (fn [x] [key x]) coll)) ;;put the key in front of every
element in data
(defn d-map [ colls]
(mapcat getpairs colls)) ;;mapcat
Thank you all for your great code examples!
The goal of the function 'd-map' is to return a collection of maps
that looks like this:
({:headline this, :points 1, :comments 10}
{:headline is, :points 2, :comments 20}
{:headline me, :points 3, :comments 30})
Based on Per's example using
(defn d-map [ args]
(apply map
(fn [ vals] (zipmap (map first args) vals))
(map second args)))

And I was about to post this variant ... looks very similar to

(apply map merge (for [[k vs] args] (for [v vs] {k v})))
I think the crux is apply map... my go-to idiom for parallel
iteration over an arbitrary number of seqs.

Thanks again for these beautiful code examples!
I haven't come across (apply map ... before so this is idiom a big
step forward for me.
The same is true for the extended use of 'reduce'. I know that this
function is really powerful but I am only just beginning to understand
its potential.

The most likely cause of this problem is having a mix of numeric types (e.g.
longs and ints) as keys/key lookups in a hash map. This is broken as required

Clojure 1.3 improves the story by having Clojure's collections defy
My take on this. I know it's convoluted, I know this is probably not

Hello,
I'm having a hard time getting Clojure 1.2/swank-clojure 1.3/leiningen
1.3.1/slime working on my Macbook (10.5.8).
I can create a new project with 'lein new Project', but when I add the
dev-dependency for swank-clojure, and try to run lein deps on the
project, I get some exceptions
You've got the syntax for dev-dependencies wrong; swank should be a vector
inside a vector. But if you're on leiningen 1.3.1 anyway you can just place
the swank jar in ~/.lein/plugins to make it available to all projects
without touching project.clj.

It's pretty standard in web frameworks. I see it in nearly every MVC
framework in CFML and Grails / Rails do it too - as well as several
Java web frameworks.

Yes, this is by no means unique to funkyweb. In fact, under the hood it uses
