Question

I want to add a character to a string, and get another string with the character added as a result.

This doesn’t work:

(cons \a "abc")

Possible solutions, in order of preference:

1. Clojure core function
2. Clojure library function
3. Clojure user-defined (me!) function (such as (apply str (cons \a "abc")))
4. java.lang.String methods

Is there any category 1 solution before I roll-my-own?

Edit: this was a pretty dumb question. 🙁

Answer 1

How about:

(str "abc" \a)

This returns “abca” on my machine.

You can also use it for any number of strings/chars: (str "kl" \m "abc" \a \b).
