Promises in Common Lisp

Companion source code for the post Promises and Lisp. Contains a not-meant-for-production implementation of promises in promise.lisp and promises based CL counterparts in pcl.lisp.

Install using quicklisp by symlinking the project directory inside ~/quicklisp/local-projects/ and then run (ql:quickload :promises).

Runloop facilities are provided by iolib.

Contains no networking code, all async calls (e.g. get-tweets-for, http-get, etc.) are stubbed using runloop timers.

test[123].lisp contain some example source code to run.

You can run the test code like this:

(in-package :promises-test3)
(run-function (make-instance 'runloop) 7 #'run "foo")
