Namespaces

Using Namespaces

Every class defined in a Cleet program is part of a namespace. The classes you define go into a namespace called Main. The standard classes are in a namespace called Standard. There are other namespaces for some system libraries, like Xlib and Xft.

The code for a class can reference classes from multiple namespaces. A class automatically has access to classes in its own namespace, and to classes in Standard.

A class can also be given access to all the classes in another namespace by using the "Uses:" header:

Class: MyWindow
Uses: Xlib

x-window: XWindow;   // ie. Xlib.XWindow

Classes in other namespaces can also be referenced explicitly by giving the name of the namespace, a dot, and the name of the class:

Class: MyFont

primitive-font: Xft.Font;

create(display: Xlib.XDisplay)
{
  primitive-font =
    new Xft.Font("sans-serif-12", display);
}

Creating Your Own Namespaces

...is not supported yet. Probably it will be done through a namespaces directory in the project directory, and/or a $CLEET_NAMESPACE_PATHS environment variable.
