istr clj macro

(istr & strings)

Accepts one or more strings; emits a str invocation that concatenates the string data and evaluated expressions contained within that argument. Evaluation is controlled using ~{} and ~() forms. The former is used for simple value replacement using clojure.core/str; the latter can be used to embed the results of arbitrary function invocation into the produced string.

Examples:

user=> (def v 30.5)
#'user/v
user=> (istr "This trial required ~{v}ml of solution.")
"This trial required 30.5ml of solution."
user=> (istr "There are ~(int v) days in November.")
"There are 30 days in November."
user=> (def m {:a [1 2 3]})
#'user/m
user=> (istr "The total for your order is $~(->> m :a (apply +)).")
"The total for your order is $6."
user=> (<< "Just split a long interpolated string up into ~(-> m :a (get 0)), "
         "~(-> m :a (get 1)), or even ~(-> m :a (get 2)) separate strings "
         "if you don't want a << expression to end up being e.g. ~(* 4 (int v)) "
         "columns wide.")
"Just split a long interpolated string up into 1, 2, or even 3 separate strings if you don't want a << expression to end up being e.g. 120 columns wide."

Note that quotes surrounding string literals within ~() forms must be escaped.
