Arybo is a software for manipulating such expressions using bit vectors and gives a bit-per-bit symbolic representation.
The ANF (Algebric Normal Form) form is used, which basically represents boolean expressions using the XOR and AND operators.
The whole documentation is available here: https://pythonhosted.org/arybo/
Under Linux/OSX/Windows, Arybo can be installed through pip for Python 2 and 3:
$ pip install arybo
Please note that Python 2 support for pytanque under Windows isn't available, as the official compiler for Python extensions is Visual Studio 2010, which can't compile libpetanque.
You will need at least clang 3.5 or GCC 4.9 to compile the python extension "pytanque" under Linux/OS.
Users of Ubuntu 14.04 need to install GCC 6. See the documentation for detailed instructions: https://github.com/quarkslab/arybo/blob/master/docs/source/setup.rst#notes-for-ubuntu-1404.
More details on the installation process can be found here: https://pythonhosted.org/arybo/setup.html
To quickly use Arybo, you can the IPython shell by simply launching
# Starts an IPython interactive shell with 8-bit symbolic variables defined $ iarybo 8 In : x|0x7f Out:Vec([ 1, 1, 1, 1, 1, 1, 1, x7 ]) In : (x^y)&a Out: Vec([ ((x0 * a0) + (y0 * a0)), ((x1 * a1) + (y1 * a1)), ((x2 * a2) + (y2 * a2)), ((x3 * a3) + (y3 * a3)), ((x4 * a4) + (y4 * a4)), ((x5 * a5) + (y5 * a5)), ((x6 * a6) + (y6 * a6)), ((x7 * a7) + (y7 * a7)) ])
