extracting integer's data into my txt file With Clojure

Question

I'm new with clojure, and i want extracting the data (only the integer numbers) in txt file for a differents processing.

in the first time i want to extract the integer data which are on the txt file : ({score 1} {:score 2} {:score 3} {:score 4} {:score 5} {:score 6} {:score 7} {:score 8} {:score 9} {:score 10} {:score 11} {:score 12} {:score 13} {:score 14} {:score 11} {:score 12} {:score 13} {:score 14} {:score 15} {:score 16} {:score 17} {:score 18} {:score 19} {:score 20} {:score 21} {:score 22} {:score 23} {:score 24} {:score 11} {:score 2} {:score 3} {:score 5} {:score 8} {:score 4} {:score 5} {:score 2} {:score 2} {:score 8} {:score 4} {:score 7} {:score 5} {:score 2} {:score 5} {:score 5} {:score 2} {:score 6} {:score 2} {:score 5} {:score 2} {:score 3} {:score 5} {:score 2} {:score 3} {:score 5} {:score 23} {:score 5} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 7} {:score 0} {:score 0} {:score 0} {:score 0} {:score 0} {:score 0} {:score 0} {:score 0}

after this i want to extract a data on another file txt for apply the the differents opération between all of data .

the second txt file is like :

   `  <  name 1>: <45>   <name 2 >: <78>     <  name 3>: <100>  <name 4 >: <8> `

if I am correct you need data like :

(1 2 3 4 5 6 7 8 9 10 11 12 13 14 11 12 13 14 15 16 17 18 19 20 21 22 23 24 11)

if so then your solution is right here

(map :score (read-string(slurp "file-location")))

thank you for your response , exactly it's what i nedd .. but when i try to apply it in another format i have an error , the format is like : `< name > : < 25 > < name > : < 30 > < name > : < 5 > < name > : < 15 >` i'm using this syntax : (map :< (read-string(slurp "file-location"))) can you tell me where is a probleme in my function ? – ELM Mar 25 '15 at 10:05
please provide me exact data so i can help you..? – piyushmandovra Mar 25 '15 at 10:10
that is mean i can't read a string on another format , like my second file txt ? – ELM Mar 25 '15 at 10:32
and if i'm right , can'i covert my txt file to a edn file ? i'm sorry for these a lots of questions by i need to resolve a probleme today – ELM Mar 25 '15 at 11:39
dude check here http://conj.io/ all clojure higher order function here. hope it will help, if i will come up with soln will update. – piyushmandovra Mar 25 '15 at 11:48

Here's a solution for your second problem (which is really unrelated to your first which was nicely formated as EDN values).

For this sample (foo.txt):

<foo 1>: <45> <bar 2>: <78> <baz 3>: <100> <qux 4>: <8>

The following creates a map of the names to values:

(defn data-to-map [f]
  (reduce (fn [acc i] 
            (assoc acc (nth i 1) (nth i 2)))
          {} 
          (re-seq #"<([^>]+)>: <([^>]+)>" (slurp f))))

It uses a regex to break up your pattern into <some name>: <some value> and puts them in a map using the name as key.

Note, in your question you place the colon right next to the close bracket, if there are spaces (as in your comments to @piyushmandovra) then you'll have to adjust the regex to suit with additional \s whitespace values.

Example repl output:

user> (data-to-map "foo.txt")
{"qux 4" "8", "baz 3" "100", "bar 2" "78", "foo 1" "45"}

If you only want values, and not names from your second sample (not sure why, but that's what you originally asked for)

(defn data-vals-to-array [f] 
  (reduce (fn [acc i] 
            (conj acc (nth i 2)))
          []
          (re-seq #"<([^>]+)>: <([^>]+)>" (slurp f))))

with example

user> (data-vals-to-array "foo.txt")
["45" "78" "100" "8"]

In this case, it discards the name and just conjs the data into the vector.

You could replace the reducing function to simply #(conj %1 (last %2)) but I kept it similar to the map example for clarity.

I've kept everything as strings for simplicity. If your data is good enough, parse the integers using this SO answer

Thank you very much for your ansewers , these is all what i'm checked !!! Tahnks — ELM, Mar 26 '15 at 01:34
