New Kojo Release — 2.4.04

I’m pleased to announce a new release of Kojo. Highlights include:

• Support for Esperanto, contributed by Christoph Knabe.
• A more responsive GUI while making big drawings at full speed.
• A preview version of a visual challenge framework to get young learners going with explorations of numbers, angles, programming, systematic thinking, etc. You can run this in a couple of ways:
  • Via Kojo-Web.
  • By downloading the getting started file and running it within Kojo.
    
• A preview version of a new turtle for younger children. Here’s a sample session with the new turtle:

  clr
  val za = nt // create a new turtle called za
  za fd 100 // one command per line
  za rt 90
  za fd 100 rt 90 fd 100 rt 90 // many commands per line
  // only one-arg commands can be used without parens
  za jt (0, 0) lt 90 
  
  // teach za new tricks
  za teach 'sq cmds {
    za fd 100 rt 90 fd 100 rt 90
    za fd 100 rt 90 fd 100 rt 90
  }
  
  za teach 'sqn cmds { n =>
    rpt(4) { za fd n rt 90 }
  }
  
  za teach 'colrsq cmds { (n, c) =>
  za fc c
    rpt(4) { za fd n rt 90 }
  }
  // use the new commands
  za sq () sqn 80 colrsq (70, green)

As always, the new version is available from the Kojo Download Page.

Enjoy!
