Promise-File-Based Brainfuck Interpreter/Compiler!

Easily compile brainfuck code right inside your machine This compiler was written in Javascript to fit Node Standards MIT License in effect

Setting up

Install

For now, we're only available on NPM

npm install node-bfi

Usage

Let's write a simple brainfuck program to print "Hi"
Brainfuck manipulates memory directly, and so, uses ASCII to display letters.
Capital H: 72
Lowercase i: 105
Now we are tasked with figuring out how to get numbers this high without having a long string of pluses, and also

Accepted Characters and Their Operations

In brainfuck, you use pointers to select which memory slot to manipulate. These are:

>

For moving forward

<

For moving backward

.

To Log

,

To accept input

+

For adding 1 to the current memory slot

-

For removing 1 from the current memory slot

[

To initialise a loop
And finally

]

To close a loop.

Doesn't seem too complicated, right?

Wrong.
Anyway, back to writing 'Hi'
Here, We can use the brainfuck code:

>++++++++++ Ok. So here we are adding 10 to the first memory slot 

Now anything between those to greater than and less than signs is what we 

will be multiplying 10 by

[-><] * 

Lets add 7 

for 70

[->*******<]> *

Wait, but now we only have 70 and we need 72! No biggie

lets add another 2

[->*******<]>++ *

Nice now we have 72

But wait; we arent logging this stuff!

No biggie again all we need to do is add a period to the end of that

[->*******<]>**.

Great! Now he have a capital H

Now for the lowercase i

remember that i was 105

lets multiply by 15

>+++++++++++++++

Great now for the loop

We can multiple by 7

[->+++++++<]>.

Thats it! Really. *

Awesome, now we have the brainfuck code. Let's put it in a file named 'hi.bf'It also must be in a directory called 'bf'Now Let's write this simple javascript program

Javascript code

const bfi = require('node-bfi')
bfi('hi.bf').then(console.log) //Output: Hi

Remember, this is promise based.
