The Common Lisp Omnificient GUI, CLOG for short, uses web technology to produce graphical user interfaces for applications locally or remotely, ie as web applications.

To load this package and use the tests:

1. cd to the CLOG dir (the dir should be one used by QuickLisp lime ~/common-lisp)
2. Start emacs/slime or your common lisp repl in that directory.
3. In the REPL run (ql:quickload :clog)
4. Then (load "~/common-lisp/clog/test/test-clog.lisp) (clog-test:test)

Documentation for CLOG in markdown can be generated with

Sample CLOG app with code base so far:

(defpackage #:test-clog
  (:use #:cl #:clog)
  (:export test))

(in-package :test-clog)

(defvar *last-obj*)

(defun on-new-window (win)
  (create-child win "<button>test</botton>")
  (create-child win "<H2>Cool!</H2>")
  (setf *last-obj* (create-child win "<button>a</button>")))

(defun test ()
  (print "Init connection")
  (initialize #'on-new-window :boot-file "/debug.html")
  (print "Connection set")
  (print "Open browser")
  (open-browser))
