Smalltalk VisualWorks Environment: Runtime Architecture Overview

Learn about the Smalltalk VisualWorks environment's runtime architecture, including the virtual machine, image, and sources. Understand how bytecodes are compiled into native code by a just-in-time compiler and the role of sources and changes in development. Explore features like Inspector, Debugger, SUnit tests, and Integrated version management. Discover the importance of versioning, code change tracking, and how to recover your code in case of power failure. Experiment, learn, and explore the comprehensive coding environment.

Presentation Transcript

  1. The VisualWorks Environment

  2. Smalltalk Run-Time Architecture • Virtual Machine + Image + Changes and Sources • Image = bytecodes • Sources and changes = code (text)

  3. Runtime Architecture • The byte-code is in fact translated into native code by a just-in-time compiler. • The source and the changes are not necessary for interpreting the byte-code, this is just for the development. Normally they are removed for deployment. • An application can be delivered as some byte-code files that will be executed with a VM. The development image is stripped to remove the unnecessary development components.

  4. Mouse Semantics

  5. Launcher

  6. Browsing a class

  7. Browsing methods

  8. Inspector • To look inside objects • anObject inspect

  9. Debugger!!!

  10. ChangeList To recover from power failure!!

  11. SUnit: TestRunner open

  12. Tests...

  13. Workspace: to edit code snippet

  14. Store • Integrated version management • Check in / out • Back end postgres/oracle • Based on packages and bundles • no scope only deployment/source management concepts

  15. Published Items

  16. Package: Versioning Code

  17. Change your Mind • Everything you do is recorded !! • So try and learn how to recover your code • You are smart so • experiment, • learn for you, browse, • all the code is there
