Re: Idiomatic Way to Build String or Simply Use StringBuilder

Everybody, thanks for all your responses. conj to vector feels good so that's what I'm playing with now. Michael, in answer to your question, and this may be more detail than you bargained for, I'm playing around with a little state machine parser. It actually doesn't do much now, but baby step

Re: Idiomatic Way to Build String or Simply Use StringBuilder

Start with an empty vector, say v. conj your strings to the vector at the various points in your code, so at the end v will be something like ["this" "is" "a" "string"] Then, when you're done, apply str to the vector, i.e., (apply str v) to get "thisisastring" str uses a string builder behind the

Thanks for the response. What if you are appending over different lines of code? Would it be slightly more efficient to use one StringBuilder or not worth the bother. On Sep 29, 11:32 pm, Stuart Campbell wrote: > On 30 September 2010 12:48, HiHeelHottie wrote: > > > > > Is there an idiomatic

Idiomatic Way to Build String or Simply Use StringBuilder

Is there an idiomatic way to build up a string over different lines of code? Or, should one simply use StringBuilder. -- You received this message because you are subscribed to the Google Groups "Clojure" group. To post to this group, send email to clojure@googlegroups.com Note that posts from
