A big bugfix is applied to this package due to the technique Python uses to import modules.

In previous versions, when brainfuck_to_function is called, it creates a module named _foo, which is imported. But Python also stores it into a cache, that means when you call brainfuck_to_function again, the new module would not be imported, which causes a function the same as the previous function is returned.

However, in this version and higher, a module with a random name is created instead, which fixed the bug.

Fast Brainf**k

The real name of this package is not fast-bf, it's fast-brainf**k.

To install it, use the command

pip install fast-brainfuck

You also need a C++ compiler.

To use the package, run like this:

>>> from fastbf import brainfuck_to_function
>>> code='++++++++[>++++++++<-]>++++++++.>++++++++++++[>++++++++<-]>+++++.+++++++..+++.>++++[>++++++++<-]>.<<<<+++++++++++++++.>>.+++.------.--------.>>+.'
>>> func=brainfuck_to_function(code) # This will take several seconds, because the C++ compiler is compiling your code.
>>> func
<built-in method run of PyCapsule object at 0x0000022568364150>
>>> func() # About 3x faster than using a brainfuck interpreter implemented in C++.
Hello World!

You can also convert brainf**k to Python modules by writing setup.py like this:

from fastbf import dist_brainfuck
code='++++++++[>++++++++<-]>++++++++.>++++++++++++[>++++++++<-]>+++++.+++++++..+++.>++++[>++++++++<-]>.<<<<+++++++++++++++.>>.+++.------.--------.>>+.'
dist_brainfuck(
    code,modulename='hello'
)

Then run python setup.py build_ext --inplace (Do not run other commands, will not work). That will created a Python extension module and hello.py, you now can import it in other scripts:

import hello
hello.run() # Hello World!

Note that moving the pointer to the left of the origin causes UNDEFINED BEHAVIOR in this version, that's why I changed the Hello World code. The version 2.0.6 and 2.0.7 are omitted here, because they are already yanked.
