dispatch the response to CALLBACK. If the code to be evaluated comes from a buffer, it is preferred to use a nil FORM, and specify the code via the BOUNDS argument instead. This function is the main entry point in CIDER's interactive evaluation API. Most other interactive eval functions should rely on this function. If CALLBACK is nil use `cider-interactive-eval-handler'. BOUNDS, if non-nil, is a list of two numbers marking the start and end positions of FORM in its buffer. ADDITIONAL-PARAMS is a plist to be appended to the request message. If `cider-interactive-eval-override' is a function, call it with the same arguments and only proceed with evaluation if it returns nil."

(:use clojure.string). Instead, use require with :as to specify a prefix, e.g. (ns your.namespace.here (:require [clojure.string :as str])) Design notes for clojure.string: 1. Strings are objects (as opposed to sequences). As such, the string being manipulated is the first argument to a function; passing nil will result in a NullPointerException unless documented otherwise. If you want sequence-y behavior instead, use a sequence. 2. Functions are generally not lazy, and call straight to host methods where those are available and efficient. 3. Functions take advantage of String implementation details to write high-performing loop/recurs instead of using higher-order functions. (This is not idiomatic in general-purpose application code.) 4. When a function is documented to accept a string argument, it will take any implementation of the correct *interface* on the host platform. In Java, this is CharSequence, which is more general than String. In ordinary usage you will almost always pass concrete strings. If you are doing something unusual, e.g. passing a mutable implementation of CharSequence, then thread-safety is your responsibility." :author "Stuart Sierra, Stuart Halloway, David Liebke"} clojure.string (:refer-clojure :exclude (replace reverse)) (:import (java.util.regex Pattern Matcher) clojure.lang.LazilyPersistentVector))
