These three files illustrate a way to implement Common Lisp syntax coloring in the editor.
(example-edit-file "editor/syntax-coloring/defsys")
(example-edit-file "editor/syntax-coloring/syntax-coloring")
(example-edit-file "editor/syntax-coloring/pkg")
Note: the editor now has built-in syntax coloring for Lisp mode buffers. If you run the example code above, it will override the built-in syntax coloring.
