argh i come back to paste in my answer and you beat me to it :(
i was gonna say:
(let [s ""@key1 this is a value @another-key and another value
@test1 and other value""]
(reduce (fn [m [_ k v]] (assoc m k (string/trim v))) {} (re-seq
#"(@[\w-]+)([^@]*)" s)))
much the same...

I think `for' is cleaner than map + anonymous function:
(into {}
(for [[_ k v] (re-seq #"(@[^ ]*) *([^@]*)" s)]
[(keyw
You could use a regexp to pick out the key and the value - something like
this:
(into {}
(map (fn [[_ x y]] [(keyword x) (clojure.string/trim y)])
(re-seq #"(@[^ ]*) *([^@]*)" s)))

Hi,
I would like to generate a hashmap from a string. The key portions of
the string will have some a prefix such as @ to define that they are
a key. So the following string
"@key1 this is a value @another-key and another value @test1 and
other value"
would get converted to.
{ :@key1 "this
Did you try this
(apply hash-map (partition 2 (split (slurp "data") #",")))

Thanks a lot for all the answers :)
I've been busy trying to understand all the scripts that you posted.
The code works but I also wanted to know why.
I'm new to Clojure and it's hard for me to understand "advanced code",
but looking through the docs and the api I'm learning a lot.
Cheers!

Or, better yet,
(into {}
(->> (str "{" (slurp "data") "}")
read-string
(map (fn [[k v]] [(keyword (str k)) v]

I'm not the only one who overlooked that! :o) Might just as well use
strings as keys. But OK, try this:
Using 'apply hash-map' doesn't handle the transformations.
Note the original post requested keywords for keys and integers for
vals in the output.

I expected this to work:
(into {} (partition 2 (split (slurp "data") #",")))
But unfortunately, `into' doesn't seem to allow pushing lists of pairs
into a map. But vectors are allowed:
(into {} (map vec (partition 2 (split (slurp "data") #","
Can somebody explain why vectors are allowe

Ken,
I've done my "homework", and of course you were right, and me wrong. At some
point in my reasoning I've conflated number of object allocations with
number of tr

Here is what I came up with ...

Hi,
I have a string of data and I would like to get a map {:key
value, :key value, …}
How could I do that?
I've got:
user> (split (slurp "data") #",")
["0" "2" "1" "5" "2" "8" "3" "15" "4" "9"]
And I would like:
{:0 2, :1 5, :2 8, :3 15, :4 9}
Any idea?
Thanks.
