Cat now plays with turtles.

I’ve just made a new release of Cat (version 0.10.4). I’ve fixed several bugs in the standard library, added some new functions, renamed a couple of functions, and added a turtle graphics library (a la Logo). The graphics library is still in its early stages but I was able to generate the following image:

rotating square pattern

The program for generating this pattern is:

#load graphics.cat
window [blue pc 5 pw [100 square 15 rt] 24 repeat] render
“c:\tmp\tmp.png” save

  • window = create graphics window 
  • pc = set pen color
  • pw = set pen width
  • square = draw square
  • rt = right turn
  • render = tell window to execute the function
