BackroomsTDP

BackroomsTDP is a programming langauge created by User:Miui. TDP stands for "ternary digit pointer" and "Backrooms" is a reference to the way programs seem to no-clip through a wall.

examples

input is associated with :/ string and output is formatted by \ i.e. Slashalash

Morse-code SOS

example type: (pulsed)
This type of code (denoted by sequential quotation marks) is a pulsed program.
This code would generally output either a quine of brainfuck code for SOS (or actually step through bf execution and combine the signal.)

!:/"!  ! !!  !  ! !!  !  ! !!""!  ! ! !  !  ! !  !  ! !""!  ! !!  !  ! !!  !  ! !!"
\/

example type: (stream)
This type of code steps through Soh_supplementary_private_use_area-b_u+10fffe execution, but the signal is already combined and is considered "private" so it only outputs a quine.

!:/ !!!""!""!!!""!
\/

"Hello, World!"

example type: (stream)
This type of code is capable of streaming an encoded message.
ASCII.
