PIPES

PIPES is a image-based 2D programming "language". It follows "pipes" and executes operations when reaching pipes with specific colors. Most operations work on the stack, but you can save and load from memory.

Features

• Drawing programs
• No more writing programs
• Input characters
• Output numbers and characters
• Basic arithmetic operations
• Comparisons
• Saving and loading to/from memory

Planned

• Better input processing
• Custom palettes
• Better debugging
• Better editing (custom IDE?)

Install PIPES:

$ npm install pipes-lang -g

You can use this palette file for Paint.NET.

Usage

  Usage: pipes [options]

  Options:

    -V, --version       output the version number
    -d, --debug         Debug mode
    -s, --strict        Strict mode
    -i, --input [args]  Input arguments
    -p, --stepwise      NOT YET IMPLEMENTED! Stepwise execution
    -h, --help          output usage information

Pipes

The program will always try to go straight, then right and then left.

Pipes aren't allowed to touch the image borders!

This is the standard palette, in the future I want to make it easy to use custom palettes.

Meta Pipes

Color	Code	Name	Meaning
White	0,0,0	background	is ignored
Black	255,255,255	default pipe	guides program
Grey	127,127,127	blockade	low priority(only enters if there's no other way)
Green	0,255,0	entry	program starts here
Red	255,0,0	exit	program stops here

Stack Operation Pipes

Color	Code	Name	Meaning
Blue	0,0,255	push	the only pipe that needs an parameter afterwards, pushes the following pixel color number to the stack
Yellow	255,255,0	remove	removes the top element from the stack
Gray	127,127,127	blockade	low priority(only enters if there's no other way)
Spring Green	0,255,144	stack to memory	saves the second element on the stack to the adress provided by the first element, the first element is removed
Cyan	0,225,255	memory to stack	pushes the element at the adress provided by the top element on the stack and removes the adress element
Malibu	127,127,255	duplicate	duplicates the top element on the stack
Electric Violet	178,0,255	swap	swaps the top two elements

Arithmetic Pipes

Color	Code	Name	Meaning
Japanese Laurel	37,127,0	add	removes E1, E2 and pushes E1+E2
Pigment Indigo	87,0,124	subtract	removes E1, E2 and pushes E2-E1
Cedar Wood Finish	124,24,0	multiply	removes E1, E2 and pushes E1*E2
Orient	37,127,0	divide	removes E1, E2 and pushes E2/E1

Control Flow Pipes

Color	Code	Name	Meaning
Pumpkin Skin	168,97,11	compare	compares E2 to E1, and changes direction depending on the result. equal: straight, greater: right, less: left
Blue Chalk	248,214,255	teleport absolute	program jumps to position x = E2 y = E1
Baja White	255,251,214	teleport relative	program jumps on position x = x+E2 y = y+E1

I/O Pipes

Color	Code	Name	Meaning
School Bus Yellow	255,216,0	input	no effect (yet)
Blaze Orange	255,106	output	removes the top element from the stack and prints it
Chardonnay	255,206,127	char output	removes the top element from the stack and prints the char with the char code provided

All the color names are only the names of the nearest named colors.

Examples

Basic I/O

When you input "r" it will output "right", when you input "l" it will output "left, otherwise it will return "-1".
