Chapter 1: Introduction

LindenMASM is an esoteric programming language I designed for the purposes of drawing Lindenmayer systems. It uses an Assembly-like syntax, hence the name LindenMASM. The original reason I made the language was for a code-golf challenge, which was to create a LindenMASM interpreter in the fewest bytes possible. Since this was too similar to a challenge that had already been made, I scrapped the idea, but held on to the interpreter.

The interpreter was written in Python 3.4, and does all of the drawing using a Turtle object. You can download the interpreter here.

Chapter 2: Syntax

There are only a few functional keywords in LindenMASM, 8 to be exact.

STT - Begins every LindenMASM file.
AXI $ - Sets the axiom (initial state) of the system.
- $ is a series of commands/variables/constants, ranging from the built-ins plus any user-defined functions.
DEG $ - Sets the degree of which all turns will follow, default is 90.
MOV $ - Sets the move distance of which all position adjustments will follow, default is 10.
INC $ - Sets the number of iterations the generation should go through, default is 0.
SET $ # - Sets a constant $ to a specified command #.
- $ should be a character that is not one of []+-.
- # will either be a 0 or a 1, where a 0 corresponds to the constant being one that draws forward, and a 1 corresponds to the constant being one that moves fowards.
RPL $ # - On every iteration, variable/constant $ will be replaced with the command/variable/constant string #.
- $ should be a character that is not one of []+-. It does not need to be SET to be replaced.
- # is a string of commands/variables/constants that $ should be replaced with.
END - Ends every LindenMASM file.

Each keyword should be placed on a new line. Every file should start with STT and end with END.

Chapter 3: Commands

There are only four built-in commands, however with these you can do a bunch of stuff!

+ - Rotates the pointer to the right DEG degrees.
- - Rotates the pointer to the left DEG degrees.
[ - Saves the pointer's coordinates and heading to a list.
] - Pops the last value of a list and sets the pointer's coordinates and heading to that.

Chapter 4: Examples

Dragon Curve, n = 12

Code:
STT
INC 12
AXI FX
SET F 0
RPL X X+YF+
RPL Y -FX-Y
END

This will draw something like this:

Fractal Tree, n = 6

Code:
STT
AXI X
DEG 25
MOV 2
INC 6
SET F 0
RPL X F-[[X]+X]+F[+FX]-X
RPL F FF
END

This will draw something like this:

Thanks for reading! The language isn't expansive or anything, but it's fun to play around with! Biggrin

dude, this is awesome. I might start using this for vector generation

Holy crap that looks fun. I might port this over to Python2.

I think the only thing needing changing is the tracer call, since that's not supported in Py2 (at least, the same way it is in Py3).
