HighLevelBF

Generate Brainfuck code by using a slightly higher level language I made up, BfGen. Supports 8-bit wrapping brainfuck.

Examples

A program that prints the alphabet, one character per line, but replaces every three character by "!" (i.e. C, F, I, ...).

The BfGen Code (the one you write)

int8 letter = 'A'
int8 countDown = 26
int8 lineFeedAscii = 10
int8 isPrintLetter = 2
int8 exclamation = '!'

while countDown
	if isPrintLetter
		print letter
		isPrintLetter -= 1
	else
		print exclamation
		isPrintLetter += 2

	print lineFeedAscii
	letter += 1
	countDown -= 1

Verison 1 - Features

Variables

The only available variable type is int8 - A 8-bit integer. When assigned a char, it will take the ascii value of the char.

Initialisation

Variable initialisation is to be done in the beginning of the code only.

int8 myVar1 = 12
int8 myVar2 = 'A'

Assignment

You can only increment or decrement a variable's value by a fixed amount; it is not possible to assign a fixed value to it.

myVar1 += 10
myVar2 -= 1

If/Else

True if the value of the variable is not zero, otherwise false.

if myVar1
	myVar2 += 1
else
	myVar2 += 3

While

While the variable is not zero.

while myVar1
	myVar1 -= 1

Read

Not supported in V1.

Print

Prints the value of the variable as an ASCII character, just like the .command in brainfuck.

int8 myVar1 = 'B'
print myVar1
