Derpcode

derpcode is a tape-based esoteric programming language based on internet slang. derpcode consists of two objects: a one-ended tape of zero-initialized binary values, and a pointer.

Commands
derpcode has five commands, although an expansion to achieve Turing-complete status is planned.

All non-command symbols are ignored. Additionally, the two punctuation commands are ignored unless preceded by either another command or a whitespace character.

The tape is left-ended, and initializes with all zero-valued cells. A  cell exists for structural purposes only.

A derpcode program is terminated by flipping the 0 cell, decrementing the pointer into the -1 cell, and executing the print command. The last line of all derpcode programs is therefore  In any other context, non-incrementing commands are ignored while on the -1 cell, so it's best not to go there.

Implementation
A full implementation exists here, written by User:Conor O'Brien in node js.

A runtime interpreter written in Python is currently in development, and a compiler to C is planned.
