Live Cells CL

[!CAUTION] This software is still in beta, and will likely experience rapid changes before the first official release.

Live-Cells-CL is a library that adds reactive programming to lisp. The functionality of the library is ported from Live Cells for Dart.

Examples

[!NOTE] This section contains examples demonstrating the main features of the library. Head to the documentation, for a short tutorial.

Cells (reactive containers for data) are defined using DEFCELL

(defcell first-name "John")
(defcell last-name "Smith")

Cells can be defined using arbitrary expressions that reference other cells:

(defcell full-name
  (format nil "~a ~a" first-name last-name))

Cells are observed with LIVE:

(live
  (format t "Hello ~a~%" full-name))

Changing the value of a cell, using SETF, results in the live block being run:

For example changing the values of FIRST-NAME and LAST-NAME:

(setf first-name "Jane")
(setf last-name "Doe")

results in the following being printed:

Hello Jane Smith
Hello Jane Doe
