User Interface

• There can be a wide range of User Interfaces.
• I used to use a line mode UI with OPS5, where you typed in the WM items, and it printed out rules that fired and results.
• Other systems like Kappa-PC have a relatively sophisticated UI.
• Clips also has a line mode interface.
• An additional set of features is not for the user but for the developer.
  • You want a rule editor, a WM editor, UI editor, and a debugger.
  • Clips has debugging facilities accessible through the command prompt. Note that it is really useful to develop a .clp (text) file and load it in frequently. There are also quite a few facilities available through the menus (e.g. watch window and fact window).
