API for strint
- ()
by Chas Emerick
clojure-contrib is now deprecated
clojure-contrib is no longer being developed or maintained.
Rather than a single, monolithic, contributions library, Clojure now has
a set of separate libraries for each unit of functionality. The libraries
are in the Clojure GitHub organization at
https://github.com/clojure.
API documentation of the libraries can be found at
https://clojure.github.io.
If you're looking for a specific function or namespace from the old
clojure-contrib, see
"Where Did Clojure.Contrib Go".
Full namespace name:
clojure.contrib.strint

<<
macro
This library, clojure-contrib, is deprecated. See here for more information.
Usage: (<< string)
Takes a single string argument and 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=> (<< "This trial required ~{v}ml of solution.")
"This trial required 30.5ml of solution."
user=> (<< "There are ~(int v) days in November.")
"There are 30 days in November."
user=> (def m {:a [1 2 3]})
#'user/m
user=> (<< "The total for your order is $~(->> m :a (apply +)).")
"The total for your order is $6."
Note that quotes surrounding string literals within ~() forms must be
escaped.
