Background Information on Smalltalk

Smalltalk's History

The Smalltalk system with it's OOP, Live Coding, Code Browser, Refactoring tools, MVC, etc. has been a major influence on, not just the Apple Lisa/Macintosh, but also on Agile, Clean Code, Unit Testing (SUnit), TDD, Design Patterns, XP, MVVM, ...

Then it became overshadowed by C++, and finally became a niche in the 90's when IBM united with Sun Microsystems against Microsoft and switched from Smalltalk to Java and Sun moved the Strongtalk team from Smalltalk to Java.

VisualWorks is still around as a commerical grade Smalltalk (and also the origin of the MVVM pattern) while Squeak is aimed at the educational market and has replaced MVC with Morphic. E.g. the first versions of Scratch were written with Squeak.

Distribution

When you go to look for a Smalltalk implementation, you'll usually find these things:

  • Compiler

    Compiles Smalltalk into another language. Most compilers are part of a Smalltalk Image running inside a Smalltalk VM and generate bytecode suitable for that VM.

    E.g. Amber compiles Smalltalk into Javascript.

  • Interpreter

    Compiles and executes the code at once.

    E.g. GNU Smalltalk.

  • Virtual Machine (VM)

    The book Smalltak-80 The Language and It's Implementation describes a common Smalltalk VM.

    Smalltalk VMs usually mimic a complete operating system complete with a bitmapped display to be able to run old Smalltalk images.

    E.g. Squeak, which is based on the the book but was been adjusted to deliver better performance.

  • Just-In Time Compiler (JIT)

    A VM which also compiles parts into native machine code.

    E.g. Strongtalk, which adds optional type checking to Smalltalk and whose JIT layed the foundation for todays Java (HotSpot) and JavaScript (V8) VMs.

  • Image

    An image to run in a VM. Old ones are available starting from the 1972 till today.

Background Information on Smalltalk
Smalltalk's History
The Smalltalk system with it's OOP, Live Coding, Code Browser, Refactoring tools, MVC, etc. has been a major influence on, not just the Apple Lisa/Macintosh, but also on Agile, Clean Code, Unit Testing (SUnit), TDD, Design Patterns, XP, MVVM, ...
Then it became overshadowed by C++, and finally became a niche in the 90's when IBM united with Sun Microsystems against Microsoft and switched from Smalltalk to Java and Sun moved the Strongtalk team from Smalltalk to Java.
VisualWorks is still around as a commerical grade Smalltalk (and also the origin of the MVVM pattern) while Squeak is aimed at the educational market and has replaced MVC with Morphic. E.g. the first versions of Scratch were
written with Squeak.

Distribution
When you go to look for a Smalltalk implementation, you'll usually find these things:
  • Compiler
    Compiles Smalltalk into another language. Most compilers are part of a Smalltalk
Image running inside a Smalltalk VM and generate bytecode suitable for that VM.
    E.g. Amber compiles Smalltalk into Javascript.
  • Interpreter
    Compiles and executes the code at once.
    E.g. GNU Smalltalk.
  • Virtual Machine (VM)
    The book Smalltak-80 The Language and It's Implementation describes a common
Smalltalk VM.
    Smalltalk VMs usually mimic a complete operating system complete with a bitmapped display
to be able to run old Smalltalk images.
    E.g. Squeak, which is based on the the book but was been adjusted to deliver better
performance.
  • Just-In Time Compiler (JIT)
    A VM which also compiles parts into native machine code.
    E.g. Strongtalk, which adds optional type checking to Smalltalk
and whose JIT layed the foundation for todays Java (HotSpot) and JavaScript (V8) VMs.
