Braingasm

Braingasm is a super-set of brainfuck, and extends the 8 original instructions with the concept of prefixes and registers.

The original idea for the language was to combine brainfuck and assembly code (asm), hence the name.

Prefixes

A prefix may alter the effect of an instruction in different ways. The simplest kind of prefix is a numeric literal, which makes the succeeding instruction repeat a certain number of times:

  • 5+ increases the value of the current cell by 5.
  • 7[X] Runs the loop, containing some code X, exactly 7 times.

Registers

Registers can also be used as prefixes. Registers are typically updated when other instructions are executed:

  • The z register holds the value 1 if the previous update of a cell caused it the reach the value 0. Otherwise the z register holds the value 0.
  • The # register holds the current position in the data tape. #> will move to cell 12 if the current cell is 6.

More information about the different prefixes and registers will come.
