8.4.1 Namespace to Module

The Scheme code generator introduces the “namespace to module” feature which means that a Dezyne file, when it contains a single namespace, is assumed to describe a module, such as found in languages like GNU Guile (see Guile modules in GNU Guile Reference Manual), JavaScript (Python, etc.). Similarly, foreigns are assumed to live in their own module, so that this module can be used/required/imported.

Things to note:

• Dezyne files that define more than one namespace are not supported for “namespace to module”,
• foreigns go into their own module,
• interfaces used by a foreign need to go into their own Dezyne file to avoid introducing cyclic dependencies,
• avoid the name foreign, the class <foreign>
• foreigns that use the same interfaces need to form a chain of use-module and re-export their port accessors (see Using Guile Modules in Guile reference manual).
