Hello,
I'm a Clojure newbie (many thanks to Rich Hickey and everyone involved
- it's a great programming environment) and I have some trouble with
'eval'.
What I'm trying is:
$ java -cp clojure.jar clojure.lang.Repl
Clojure 1.1.0-alpha-SNAPSHOT
user=> (let [x 1] (eval '(inc x)))
java.lang.Except
You need to unquote the x to get its value from the let. You can do
that with the tilde character inside syntax quotes:
user=> (let [x 1] (eval `(inc ~x)))

Hi,
In Rails you can create a view like this:
my_view.erb:
<%= "hello" + @name %>
I'm new to Clojure. I want to create something like the above like
this:
(defn my-view []
(str "hello" name))
The point is:
* name is not known when my-view is defined
* I don't want to pass name as a argument
Hello,
thanks everyone for replies,

I had a suspicion that something similar to this might be happening.
As I said in the first message, including a doall on the filters
prevented the issue from happening. I will relay this info back to my
friend. Thanks for the help.

Python is much more dynamic, with variable lookup happening at
runtime. In Clojure, onl
I believe the way this works in rails has to do with the order in
which variables are resolved. In this case, @name is an instance
variable that's already been assigned elsewhere (your controller).
Rails loads the view after the controller class has been instantiated.
For this to work, the view is

I'm pretty sure that you need to either name each class you want to
import inside your :import form or you need to import the package and
then each use of the classes in that package need to be manually

able to use the ns macro
Using a map of keywords is a good solution, but I think it is somewhat
