Tutorial

A tutorial: build one working Viewdata service from nothing, a step at a time. You will write a calendar — the date and time, a month as a grid, the days to come — and dial into it as a 1980s terminal would. Each step adds one capability and leaves the service running, so the framework is met in the order a service needs it. Allow about an hour.

By the end your file is calendar_viewdata/application.py, the framework’s own worked example, line for line.

• A first frame
• Menus and page numbers
• State and the lifespan
• Frames and keys
• Sequences
• The framework’s pages, and drawing your own
• Testing a service
