Thanks for your suggests~
The above piece of code is just for test.
The practical problem i want to solve is that
-->read a very big log file (each line is like that : "user id, latitude,
longitude, timeStamp")
-->statistic the number of each user (store in a map like that { id1 100 ,
id2 200, id3
I took some inspiration from Tim Baldridge's code-walking macro youtube
video (http://www.youtube.com/watch?v=HXfDK1OYpco) and updated print-foo's
`print-sexp` macro to intelligently expand the code it surrounds.
print.foo=> (print-sexp (str (+ 3 4) (+ 5 (* 6 2)) 4))3 34 4(+ 3 4) 75
56 62 2(* 6 2)
Given the source map improvements to ClojureScript, now is a good time to
present a newbie friendly guide to hacking with ClojureScript. Emphasis on
no fuss and getting as quickly as possible to productive experimentation:

Clojure data structures are immutable. clojure.core/assoc
produces a new data structure instead of changing the one you have.
You can use an atom if you need to update a map from doseq
but more likely you want to use the actual
Hi , all
I am new to Clojure.
For now , i have a piece of code :

but the repl return me {} and 0

Hi Scott,
I only began Clojure web development recently and decided to use Luminus
[1]; it brings together a bunch of frameworks (lib-nior, ring, compojure,
etc). Felt like a good starting point for me.

You can use Korma with Stuart Sierra's workflow just fine.

I'm using FW/1 (but then it's my framework, ported from CFML :) which
is based on Ring and uses Enlive and Selmer for templating. It uses
conventions rather than configuration (although you can specify routes
if you want to override configuration).

Noir is deprecated in favor of lib-noir.
Where have you seen some indication that Compojure is deprecated?

Ring seems well maintained, but Noir and Compojure are marked deprecated.
Can anyone lay out a Clojure Web library "stack" (up to templating) that is
current and maintained?
Any and all sagacious wisdom greatly appreciated - thanks!

Silly me, thank you for your replies guys!
One more question though, what if my-foo had parameters?

You are getting my-foo evaluated, remove the parens around it.

The function's arguments will be evaluated before calling it.
So the (my-foo) will be called before 'get'.

Shouldn't (my-foo) only be called in case the key isn't found? Why am I
seeing the above behavio
Thanks Malcom,
Even something really simple like showing your current project setup would be
really good for me to get going.
