Whitespace Language

Introduction

The language contains 3 different characters to represent the code: Space, Tab(\t), LF(\n).

Different combinations of characters form a series of operands that let this language be Turing-complete.

Code

Annotation

!S, T, L corresponds to space, tab and LF respectively

S S STSSTSSSL        !push number +1001000('H') to stack
TL SS                !print the character at the top of stack: 'H'
S S STTSSTSTL        !push 'e'
TL SS                !print 'e'
S S STTSTTSSL        !push 'l'
S LS                 !duplicate the top element of the stack
S LS                 !stack: ['l','l','l']
