3.11: Chapter Summary

In this chapter you have seen how to create packages, classes and methods. In addition, you have learned how to use the System browser, the inspector, the debugger and the Monticello browser.

• Packages are groups of related classes.
• A new class is created by sending a message to its superclass.
• Protocols are groups of related methods inside a class.
• A new method is created or modified by editing its definition in the browser and then accepting the changes.
• The inspector offers a simple, general-purpose GUI for inspecting and interacting with arbitrary objects.
• The browser detects usage of undeclared variables, and offers possible corrections.
• The initialize method is automatically executed after an object is created in Pharo. You can put any initialization code there.
• The debugger provides a high-level GUI to inspect and modify the state of a running program.
• You can share source code by filing out a package, class or method.
• A better way to share code is to use Monticello to manage an external repository, for example defined as a SmalltalkHub project.
