unknown recursion
Hi, I am trying to write a function to return a boolean as to whether parenthesis are balanced or not? (defn bal-parens? [parens] (let [replaced (clojure.string/replace parens "()" "") checked (re-seq #"\(\)" replaced)] (println checked) (if-not (nil? checked) (bal-parens? replaced)) (println (str "replaced is " replaced)) (if (empty? replaced) true false))) (bal-parens? "(()())") I'd expect to see true here. But my output is: (()) nil replaced is replaced is () false I can't for the life of me think why, that when checked is nil and replaced is empty the function doesn't terminate!

count occurrences of a char in a string or a collection
Hi, Is there a higher-order function(s) that count occurrences of characters in either a string or a collection?

destructure command line arguments
Hi,
I have a main function:
(defn -main [& args]
(let [{:keys [graph filepath title]} args]
(cond
(= graph "response") (graph-response filepath title)
(= graph "requests") (graph-request filepath)
(= graph "throughput") (graph-throughput filepath
Which I can invoke with this call:
(-main :graph "throughput" :filepath "./aggregate-report.csv")
However, when I create an uberjar and do this:
java -jar jmeter-graphs-0.1.0-standalone.jar :graph "throughput" :filepath
"./aggregate-report.csv"
There arguments are not destructured. Is it possible to use key value pairs
through the command line?
Many Thanks
Aidy

create vectors for each key/value pair
Hi,
I have an unsorted map:
(def my-map
{1405961887 20,
1405960895 20,
1405961919 20,
1405960927 20,
1405960959 21,
1405960991 20,
1405961023 20,
1405961055 18,
1405961087 23,
1405961119 17,
1405961151 23,
1405961183 19,
1405961215 20}
I'd like to be able to sort the map by key and then place each value pair
into a vector.
An attempt at (sorted-map my-map) returns 'No value supplied for key:
{1405961887 20 ' }
When I attempt to create a vector from the key/pairs
(map #(vector %) my-map)
I receive each key/value in a vector within a vector
([[1405961887 20]]
[[1405960895 20]]
[[1405961919 20]]
[[1405960927 20]]
[[1405960959 21]]
[[1405960991 20]]
[[1405961023 20]]
[[1405961055 18]]
[[1405961087 23]]
[[1405961119 17]]
[[1405961151 23]]
[[1405961183 19]]
[[1405961215 20]])
My goal is to create a collection of vectors to place in an Incanter
dataset:
incanter/dataset ["time" "requests"]
[[1405961887 20]
[1405960895 20]
[[1405961919 20]])
Many Thanks

reload dependencies

Calculating the number of timestamps logged within a specific time period
Hi, I have a list of epoch times which map to HTTP requests. '(1405060202611 1405060201157 1405060201361 1405060201261 1405060200391 1405060201458 1405060201705 1405060201058 1405060205062 1405060201558 1405060201761 ) I am trying to find out how many HTTP requests I have in a specified time period, so I can graph requests per second. I was thinking of using reverse and subtracting the first from the list from the second and recurring, which would give me the time period between every two requests - which is a start. Any help appreciated here. Many Thanks Aidy -- You received this message because you are subscribed to the Google Groups "Clojure" group.

Measure HTTP response times
Hi, I am developing a primitive web load test tool using a HTTP client and STM. I wondered if there was a Clojure library I could use that would give me individual HTTP response times?

split maps contained in a file
Hi,
I have a Clojure file that contains two maps.
{:a 1 :b 2}
{:c 3 :d 4}
I would like to read both maps as Clojure data structures, but if I:
(read-string (slurp maps.clj))
Only the first map is returned.
I would like to read the file and split or partition the maps and hold onto
them as two separate map data structures.
Many Thanks
Mr Empty
