Comma separated String values from vector

[sunil...@gmail.com]

Hi All,

I'm new to Clojure - 

I'm defining a vector containing string values. The requirement for me is to retrieve the String values separated by comma from the input vector.

Example: 

=> (def my-strings ["one" "two" "three"])

;; My expected output should be ;; "one", "two", "three" 

I tried interpose and join as below

=> (apply str (interpose "," my-strings))

=> (clojure.string/join "," my-strings)

both returning as "one,two,three" but I need each string surrounded by double quotes "" like in my example example.

/Sunil.

(apply str "\"" (interpose "\", \"" my-strings) "\"") might work...

hi,

i might be wrong but it seems you're looking for something like https://github.com/clojure/data.csv

cheers,

this seems to do what you want: (clojure.string/join ", " (map pr-str my-strings))

Jay beat me to it. :)

I'll add the documentation for pr-str:

(apply str (interpose "," (map #(str "\"" % "\"") [...])))

Not the most efficient way but short.

Pr-str is very slow compared to string concats....

I assume here that the strings are already escaped. Which might not be true at all.
pr-sr is safer in this regard but 6 times slower.

Thanks everyone for contributing.

=> (clojure.string/join "," (map #(str \" % \") my-strings)) works perfectly for my case and that will do for now.
