Brainf*ck interpreter

This program is a Brainf*ck interpreter inspired by the coding challenge created by John Crickett. The interpreter creates bytecode based on the Brainf*ck program and runs the bytecode.

Usage

Build the project by running:

go build -o bin/ccbf ./ccbf/cli/interpreter/main.go

Then use the interpreter on a .bf file like:

./bin/ccbf examples/mandelbrot.bf

Or run directly without building:

go run ./ccbf/cli/interpreter/main.go examples/mandelbrot.bf

Bytecode instructions

The following is a complete list of the supported operations and their bytecode representation.

Operation	Description	Bytecode	Parameters
>	Move the pointer to the right one step	1	-
<	Move the pointer to the left one step	2	-
+	Increment the memory cell at the pointer	3	-
-	Decrement the memory cell at the pointer	4	-
.	Output the character signified by the cell at the pointer	5	-
,	Input a character and store it in the cell at the pointer	6	-
[	Jump past the matching ] if the cell at the pointer is 0	7	Jump location
]	Jump back to the matching [ if the cell at the pointer is nonzero	8	Jump location
+ (repeated)	Increase value of memory cell with number of repetitions	9	Repetitions
- (repeated)	Decrease value of memory cell with number of repetitions	10	Repetitions
> (repeated)	Move the pointer to the right as many steps as repetitions	11	Repetitions
< (repeated)	Move the pointer to the left as many steps as repetitions	12	Repetitions
[-]>	Reset memory cell and move pointer one step right	13
[-]	Reset memory cell	14
[->+<] (repeated)	Move value to the right a number of steps	15	Number of steps
