BF-it

A compiler from a C-like language to Brainfuck

Always heard that Brainfuck is Turing complete but still had doubts about its computational power? Those days are over

What is this?

BF-it is a Compiler of a C-like language to Brainfuck, written in Python

You give it C-like code, and it gives you Brainfuck code with the same functionality :)

Why did you create it?

There are several reasons why I chose to create this

1. I always heard that Brainfuck is Turing complete, and therefore as strong as any other language
   • I wanted to put that to the test, and find a concrete proof that it is true
2. I find it beautiful how a seemingly bunch of nonsense characters can have a logical meaning / functionality
   • I wanted to take it to the extreme
3. I wanted to practice my developing skills
4. It seemed to be like a real challenge (and it was!)
5. But mostly, and most importantly, I did it for teh lulz

What can I use it for?

Create a Brainfuck code of your choice, send it to your friends, and tell them to run it (on some online interpreter, for example)

When they receive a bunch of nonsense which does something meaningful, they will (maybe) be amazed

How do I use it?

1. Write a C-like code (example programs included) into a file
2. Open your favorite command line interface
3. Run BF-it.py <path_to_code_file>
   • This will compile your file and create a .bf file with Brainfuck code
   • (optional parameters: -o for output file, and -r for running the compiled file)
4. Run Interpreter.py <path_to_bf_file>, this will execute the Brainfuck code

Example:

$ cat helloworld.code
int main()
{
    print("Hello World!\n");
}

$ ./BF-it.py helloworld.code
Compiling file 'helloworld.code'...
Compiled successfully to 'helloworld.bf'
$ ./Interpreter.py helloworld.bf
Hello World!

For a more interesting example,

1. Take a look at calc.code in the 'examples' directory
2. Run ./BF-it.py examples/calc.code -r
3. Play around with the interface
4. If you're brave, take a look at the generated Brainfuck code
5. If you're very brave, try to understand it (I can't)

How do I write code?

Please refer to the 'examples' directory. It contains examples and explanations for syntax, operations, flow, and more

I like it! how can I give you money?

If you like it, you can donate me some money

If you choose to donate, I will use your money to buy myself non-dairy ice cream with a flavor of your choosing

And will email you a picture of it as proof
