derpcode

A tape-based esoteric language based on internet slang.

Structure

derpcode consists of two objects: a one-ended tape of zero-initialized binary values, and a pointer (i.e., Turing "head").

Library

Command	Description
herp	Flip the current bit.
derp	Increment the pointer.
a-derp	Decrement the pointer.
.	Write the current bit and the next seven bits to stdout as an ASCII character.
?	Get an ASCII character from stdin and store it in the current bit and the next seven bits.
!	If current bit c == 1, concatenate c+4 through c+7, interpret as a 4-bit binary number d, and increment the pointer d steps.

Syntax

Any words and symbols (including whitespace) which are not defined in the above library table are ignored by the interpreter.

Initiation

Every derpcode program initiates with the commands derp a-derp.

Termination

A derpcode program is terminated by decrementing the pointer to -1 after flipping the 0 value, and running the print command. The last line of all derpcode programs is therefore:

herp a-derp.

Implementations

Implementations planned include:

[ ] python-based runtime interpreter (in development).
[ ] compiler down to C, in C.

Sample Programs

Hello World

The following derpcode program prints the phrase "Hello world!" to the screen, and exits.

derp a-derp.

Obfuscation

As derpcode is based on widespread internet slang, its ease of human readability is hard to avoid. However, as the interpreter ignores non-library terms, an easy way to obfuscate derpcode is to simply intersperse your code within another text document.
