~~==Looking under the hood==~~

−

~~Turtle Art projects are stored as a .ta file contains a [http://docs.python.org/library/json.html json-encoded] serialization of the project.~~

−

~~The json encoding of a repeat 4 forward 100 right 90 project:~~

−

[[0,"repeat",331,158,[null,1,2,null]],[1,["number","4"],417,167,[0,null]],[2,"forward",426,207,[0,3,4]],[3,["number","100"],500,216,[2,null]],[4,"right",426,246,[2,5,null]],[5,["number","90"],500,255,[4,null]],[-1,"turtle",0,0,0,0,50,5]]

−

~~The basic structure of the encoding is a list of lists, where each block has these elements:~~

−

~~# block number~~

−

~~# block name or [block name, block value]~~

−

~~# x position (depreciated)~~

−

~~# y position (depreciated)~~

−

~~# list of connections to other blocks~~

−

~~Turtles are encoded at the end of the list:~~

−

~~# -1~~

−

~~# turtle or [turtle, turtle name]~~

−

~~# x position~~

−

~~# y position~~

−

~~# heading~~

−

~~# pen color~~

−

~~# pen shade~~

−

~~# pen width~~
