Swank Clojure

Swank Clojure is a server that allows SLIME (the Superior Lisp Interaction Mode for Emacs) to connect to Clojure projects.

For any further information please refer to the original page.

REPL Testing

This is a hack that does basically two things:

  1. Add variables to the REPL which hold the last few inputs. These variables are in the namespace swank.repl-starvars and named **1, **2 and **3. The names are inspired by *1, *2 and *3, but instead of holding the last output values, they contain the last, second to last and third most recent input form that you entered to the REPL.

  2. Using these variables a new slime functionality slime-extract-test is provided. Calling this function will take your last REPL interaction and compile it into a test form suitable for using with clojure.test. The extracted test forms are simply appended to a buffer called "Testing". Using the global variable testing-buffer any other buffer can be used for collecting the tests.

Installation

Just run clojure as usual with the classpath referring to the new repository. Then start your swank server and connect from Emacs.

Add the following lines to your .emacs file:

(add-to-list 'load-path <path to swank-clojure>)
(require 'slime-extract-test)

Example usage

user> (range 7)
(0 1 2 3 4 5 6)

user> (range 3)   
(0 1 2)

user> (concat *1 *2)
(0 1 2 0 1 2 3 4 5 6)

Then hit M-x slime-extract-test and

(is (= (concat (range 3) (range 7)) '(0 1 2 0 1 2 3 4 5 6)))

gets appended to your Testing buffer.
