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.core
Overview
Functions/macros variants of the ones that can be found in clojure.core
(note to other contrib members: feel free to add to this lib)
Public Variables and Functions
-?>
macro
This library, clojure-contrib, is deprecated. See here for more information.
Usage: (-?> x form)
(-?> x form & forms)
Same as clojure.core/-> but returns nil as soon as the threaded value is nil itself (thus short-circuiting any pending computation).
Examples :
(-?> "foo" .toUpperCase (.substring 1)) returns "OO"
(-?> nil .toUpperCase (.substring 1)) returns nil
