6.6 Modules

Part of the system is implemented using load on demand modules that are loaded automatically when a function is called. Most of these modules are only useful during development, so are not needed in the application. However, in some cases the application may need some module.

The list of loaded modules can be obtained by entering

:bug-form nil

in a listener. Among other things, this prints the list of loaded modules. To get a minimal list, do:

  1. Start a fresh LispWorks image, making sure it does not load any irrelevant code (for example in your .lispworks init file):

    C:\Program Files\LispWorks>lispworks-4450 -init -
  2. Load the application and run it.
  3. Exercise the application, to ensure that any entry points for load on demand modules are called.
  4. Enter :bug-form nil in a listener. The list of loaded modules should include only modules that your application needs.

Once you know a module is required in your application, you need to load it before delivering, by calling require :

(require module-name )

Note: require is case-sensitive, and generally module-name is lowercase in LispWorks.
