# foobar - [fo]bar is [o]ther [b]rainfuck (errr.. [a]nother) [r]unner
This is just an old toy-project of mine from 2007.
It interprets [Brainfuck](https://en.wikipedia.org/wiki/Brainfuck) code. If you are a shitty programmer when
talking about pointers you will hate this Language. It is not for you. Anyway, it would be a good exercise to improve
your skills on this subject.
You can generate 32-bit ``ELFs`` on ``Linux``.
## How to build it?
For building issues you need to use [Hefesto](https://github.com/rafael-santiago/hefesto). Because I am sure that you
belong to a rare class of human being: ``The homo sapiens reader sapiens``. Just go ahead and put it to work on your system.
Once it done go to the ``foobar's`` ``src`` subdirectory and "pray" for ``Hefesto`` from there... ;)
```
foo@bar:~/src/foobar/src# hefesto
```
Now you got a ``f_ckin`` ``ELF`` called ``f_ckin`` "foobar" inside the ``f_ckin`` ``../bin`` ``f_ckin`` subdirectory.
Just ``f_ckin`` use it and go... have some fun!
## Installing
You can install it, again, using ``Hefesto``. By default it will install the ``foobar's`` binary inside ``/bin`` for
``UNIX-like`` environments and inside ``%WINDIR%`` for stuffy ``Windows`` environments.
Being inside ``src`` subdirectory, try:
```
foo@bar:~/src/foobar/src# hefesto --install
```
If you want to change the install location, try:
```
foo@bar:~/src/foobar/src# hefesto --install --prefix=
```
On ``UNIX-like`` places being ``foobar`` installed in a well-known place (let's assume ``/bin``) you can execute your
``Brainfuck`` scripts using ``shebang``:
```
#!/bin/foobar
>,>,>,>,>,>,>,>,>,>,>++++++++++.[-]<[<][>.]
```
and...
```
foo@bar:~/src/foobar/src# chmod +x sample.bf
foo@bar:~/src/foobar/src# ./sample.bf
```
Shebang!
## Using it
The usage is pretty simple:
```
foo@bar:~/src/foobar/src# ../bin/foobar bash.bf
```
When you want to know the decimal value from a ``ascii`` symbol:
```
foo@bar:~/src/foobar/src# ../bin/foobar --ascii2dec
ascii: _
```
Just type it... You can do the inverse too, from a ``ascii`` remember about its decimal value:
```
foo@bar:~/src/foobar/src# ../bin/foobar --dec2ascii
dec: _
```
Type a decimal value and then hit the ``ENTER`` key.
Okay, do you want to see the whole ``ascii`` table:
```
foo@bar:~/src/foobar/src# ../bin/foobar --asciitable
```
>"Blah-blah-blah... I can not see the entire table due to the scrolling... Blah-blah-blah."
You should use:
```
foo@bar:~/src/foobar/src# ../bin/foobar --asciitable | less
```
or
```
foo@bar:~/src/foobar/src# ../bin/foobar --asciitable | more
```
but in this case, instead of using this if I were you I would rush to read a good ``UNIX`` book. Seriously! ;)
If you want to generate an executable from your brainfuck code, you should try:
```
foo@bar:~/src/foobar/src# ../bin/foobar yourcode.bf -oyourbinary
foo@bar:~/src/foobar/src# ./yourbinary
```
The binary generated is huge and not optimized. However, I think interesting make a brainf_ck code a self-contained executable...
You should try the [LostKing.b](https://github.com/rdebath/LostKingdom)... You will get a ``44.4 MB`` binary!!! :D ... It is generating a lousy assembly based on the
basic operations from the brainfuck input... Even being boring and obvious it could generate ``C`` or any other Language (instead
of the assembly) and then the executable...
This feature is only written for ``Linux`` 32-bit environments. I am not intending to extend it anymore...
I am sick of this project... However, if you want to extend it to 64-bit, it would be simple. Windows too...
Feel free about, this is a free software! :)
