Szpakowski

An algorithmic tribute to the Polish artist Wacław Szpakowski

at this moment still work in progress...

What is it?

• Think Logo, the 'turtle' language from the eighties.
• Because Szpakowski's drawings all follow the principle of the single line.
• it has the basic commands to move the turtle:

• start(x,y): You MUST have this as first statement.
• go(distance)
• left(degrees)
• right(degrees)

• on top of that it has:

• pillars(number, length, shift, direction=DOWN): the turtle follows a pillary pattern
  • number: the number of pillars (running back and forth)
  • length: the distance per run
  • shift: in-/decrease in length
  • direction: UO|DOWN|BOTH
• moving_pillars(n, length, shift=0, direction=DOWN): the pillars move
  • number: the number of pillars (running back and forth)
  • length: the distance per run
  • shift: shift per run
  • direction: UP|DOWN
• staircase(number, size, direction = DOWN)
  • number: the number of steps
  • size: the step size
  • direction: UP|DOWN

... more functions will follow

Run

• npm run start

• the console has code completion, but right now it's limited: only once there is only 1 alternative, you can press tab to complete.

• the interpreter is based on 'Lox' from the 'Crafting Interpreters' book.

• use var to declare a variable

• print(...) prints to the console

• statements must end with ';' (//TODO remove)

• not yet:

  • loops
  • branching
