Golang compiler and interpreter for Brainfuck. Because.. why not? It's called Grainfuck because it's Brainfuck but simulated and compiled with Go, so Grainfuck (yaeh). I was looking for a little cool project, and I heard about this beautiful language: the Brainfuck. It was looking interesting, so I thought about making a compiler and an interpreter for it!
- Simulation
- Compilation
- Parser optimization
- Compiler optimization
It's in its name! This language is here to destroy your brain. Honestly, I think it looks kinda cool, a bit sus, but kinda cool ngl. Here are the instructions according to Wikipedia:
| Op | Meaning |
|---|---|
| > | Increment the data pointer |
| < | Decrement the data pointer |
| + | Increment the byte at the data pointer |
| - | Decrement the byte at the data pointer |
| . | Output the byte at the data pointer |
| , | Accept one byte of input and store its value in the byte at the data pointer |
| [ | If the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching ] command. |
| ] | If the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching [ command |
This is Go, so easy stuff
# clone repo
$ git clone https://github.com/stevancorre/grainfuck.git
$ cd grainfuck
# build
$ mkdir build
$ go build ./src -o build
# run
$ cd build
$ ./grainfuck <args>Usage
Usage of /grainfuck:
-build
Enables compilation
-mem uint
Set the memory size (default 30000)
-run
Enables simulation
Note: if you enable both simulation and compilation mode, it's going to first compile the program, then run the executable
Examples
# Display the usage
$ ./grainfuck -help
# Run file.bf
$ ./grainfuck -run test.bf
# Build file.bf
$ ./grainfuck -build test.bf
# Build and run file.bf
$ ./grainfuck -build -run test.bf
