Timefuck

Timefuck is an esoteric language based on brainfuck and TwoDucks, made by Alternative678 in December 2009.

Commands

Characters that aren't commands do nothing. Because 'v' is a command, replace it with w or u in comments.

• '+-<>.' do the same things as in brainfuck.

• '(f)' does f if the current cell is not 0.

• '|' is a label for time traveling.

• '^fv' does f in the temporal and spacial context of the last label.

Examples

|+.(^-v)

This program demonstrates Timefuck's handling of the grandfather paradox. Using the many-worlds view of space-time, this program simply arrives at the . with the current cell 0 even though that value hasn't been created yet.

Turing-completeness

Any brainfuck program can be converted to Timefuck by replacing '[foo]' with '|(^foov)'.
