One technique that I have found very useful through the years is to
automatically generate the user interface from extended/amended type
declarations of the information to be presented and/or modified. I
know other LISP developers are using similar strategies.
For example, I have a DEFPREFERENCE macro to notify the application
about which values should be user-modifiable preferences.
The application generates a Mac "Preferences" dialog based on the
various preferences declared in the application, like this:
(defpreference webmaster ""
(:documentation "The name of the webmaster")
(:description "The webmaster is the person that maintains the
(:keywords "website" "username")
Here is an old documentation page:
CL-HTTP has a module that implements the same functionality with a
very similar syntax:
This approach provides a foundation for portable user interfaces.
