Wikifunctions:LOGO

Logo, stylised LOGO is a family of imperative and functional programming languages originally used to control small robots ('turtles') for pedagogical use.

[...] Fall of 1968 after I had visited Seymour Papert and Cynthia Solomon’s first LOGO classrooms. This changed my view of computers and personal computers from just “vehicles” and “tools” to “meta-media” and “ for children in important ways also”.

— Alan Kay

It has been requested that Wikifunctions support programming in a LOGOlike language; this page is about modelling aspects of these languages using functions.

Examples of LOGOlike languages

• original LOGO
• AppleLogo
• Blockly
• KTurtle
• NetLogo from Northwestern University (homepage, browser-based, model repository)
• Scratch (license)
• Snap!
• Starlogo from MIT
  • Starlogo TNG (homepage)
  • Starlogo Nova (homepage)
  • MacStarLogo Classic
  • OpenStarLogo (archive)
  • starlogoT (homepage)
• SugarLabs Logo (homepage)
• UCBLogo
  • QLogo-GUI
• Zblocks (demo)

blocks

Some of these 'flavours' use plain text for the syntax, others use snappable blocks.

common concepts

• the turtle, or agent: the primary figure of agent-based modelling, it has associated variables
  • pen: ability to affect the environment, particularly using colors (it was a real pen on the original robots)
• the environment ('patch' in NetLogo): can be thought of as the 'patient' although variables therein can have equally potent effect
