lectronimo has been written with RubyMotion (booya), so a valid RubyMotion license is required. if you would like to run lectronimo on something other than the iOS simulator, a valid iOS developer certificate is also required
git clone git@github.com:glucero/lectronimo.git
cd lectronimo
bundle install
rake -T

right multiply [ 10 90 ]
multiple expressions are allowed on the same line
forward 100 right 90 forward 100 right 90 forward 100 right 90 forward 100 right 90
creating a polygon command:
command polygon [ sides size ] [
repeat sides [
forward size right divide [ 360 sides ]
]
]
using the new polygon command:
creating a pythagoras tree:
command pythagoras-tree [ size ] [
repeat 4 [ forward size left 90 ]
forward size left 90 forward size right 90
right divide [ arcsine divide [ 3 5 ] degree ]
forward multiply [ 3 divide [ size 5 ] ] right 90
forward multiply [ 4 divide [ size 5 ] ]
left divide [ arcsine divide [ 3 5 ] degree ] back size left 90
right divide [ arcsine divide [ 3 5 ] degree ]
forward multiply [ 3 divide [ size 5 ] ] left 90
ifelse [ more [ size 3 ] ]
[ pythagoras-tree multiply [ 3 divide [ size 5 ] ] ]
[ repeat 4 [ forward multiply [ 3 divide [ size 5 ] ] left 90 ] ]
back multiply [ 4 divide [ size 5 ] ] right 90
ifelse [ more [ size 3 ] ]
[ pythagoras-tree multiply [ 4 divide [ size 5 ] ] ]
[ repeat 4 [ forward multiply [ 4 divide [ size 5 ] ] left 90 ] ]
left divide [ arcsine divide [ 3 5 ] degree ] back size
]
using the new pythagoras-tree command:
