I was bored so i made a python compiler for brainf*ck programming language.

What is Brainf*ck?
Example Brainf*ck Program
[ This program prints "Hello World!" and a newline to the screen, its
length is 106 active command characters. [It is not the shortest.]
This loop is an "initial comment loop", a simple way of adding a comment
to a BF program such that you don't have to worry about any command
characters. Any ".", ",", "+", "-", "<" and ">" characters are simply
ignored, the "[" and "]" characters just have to be balanced. This
loop and the commands it contains are ignored because the current cell
defaults to a value of 0; the 0 value causes this loop to be skipped.
]
++++++++ Set Cell #0 to 8
[
>++++ Add 4 to Cell #1; this will always set Cell #1 to 4
[ as the cell will be cleared by the loop
>++ Add 2 to Cell #2
>+++ Add 3 to Cell #3
>+++ Add 3 to Cell #4
>+ Add 1 to Cell #5
<<<<- Decrement the loop counter in Cell #1
] Loop till Cell #1 is zero; number of iterations is 4
>+ Add 1 to Cell #2
>+ Add 1 to Cell #3
>- Subtract 1 from Cell #4
>>+ Add 1 to Cell #6
[<] Move back to the first zero cell you find; this will
be Cell #1 which was cleared by the previous loop
<- Decrement the loop Counter in Cell #0
] Loop till Cell #0 is zero; number of iterations is 8
The result of this is:
Cell No : 0 1 2 3 4 5 6
Contents: 0 0 72 104 88 32 8
Pointer : ^
>>. Cell #2 has value 72 which is 'H'
>---. Subtract 3 from Cell #3 to get 101 which is 'e'
+++++++..+++. Likewise for 'llo' from Cell #3
>>. Cell #5 is 32 for the space
<-. Subtract 1 from Cell #4 for 87 to give a 'W'
<. Cell #3 was set to 'o' from the end of 'Hello'
+++.------.--------. Cell #3 for 'rl' and 'd'
>>+. Add 1 to Cell #5 gives us an exclamation point
>++. And finally a newline from Cell #6
Config
Check config.json first, quick information about config.json;
{
"MEM": 20, // MEM is the total cells for our brainfuck program.
"DUMP_FILE": "./result/dump.py", // The dump file that will write when program finished and got some informations about the code.
"COMPILE_FILE": "./result/compiled.py", // The file that will write when brainfuck code turned into python code.
"LOG_FILE": "./result/logs.txt", // Log file for our program actions.
"DEBUG": true // Allow debug mode for compiler, will log everything to console.
}
Usage
Simple Usage;
python compiler.py ./example/fibonacci.bf
Output: ... 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89 ...
And also you can check ./result/dump.py
for some informations about program;

Wait, so you compile brainfuck into valid python code? That's so beautifully useless, a gorgeous overkill. I love it!
Yeah it compile brainf*ck code to python code, thanks!
nice
thanks!
