Programming in L-Code

Structure of a L-Code program

The L-Code language is an attempt to provide a language able to describe several Lindenmayer's systems.

An L-Code program look like almost any Lindenmayer's system textual representation. The following example is the Koch curve written in L-Code:

    iteration: 4;
    distance: 10.;
    angle: 90.;
    axiom: --F;
    F -> F+F-F-F+F;
    

This code is very similar to the Koch curve pseudo-code on Wikipedia:

    variables : F
    constants : + −
    start : F
    rules : (F → F+F−F−F+F)
    

And finally the image generated by Lindenmayer:

Name	Value type	Description
axiom	Modules	Modules from which to begin construction
iteration	unsigned integer	Iteration count
distance	unsigned float	The distance that the turtle moves when 'forward' is called
angle	float	The angle that the turtle rotates when '+' or '-' is called
