electruth is a collection of boolean logic tools. It can be used as both a command-line tool and a Python library. It understands boolean algebra (to some extent) and can be used to simplify boolean expressions using the Quine-McClusky method.
electruth can be useful if you have a truth table in need of basic shortening. electruth can also be used to compare boolean expressions, which can be very useful if you need to compare a truth table with a schematic you created based on that truth table. electruth can also be used to "destroy" complex boolean expressions into simpler ones consisting only of ANDS, ORS and NOTS.
Installing
Way #1
Just run this (requires that you have python-setuptools installed):
sudo easy_install electruth
Way #2
Get the newest version of electruth at http://metanohi.org/projects/electruth/ or at http://pypi.python.org/pypi/electruth
Extract the downloaded file and run this in a terminal:
python setup.py install
Using
Installing electruth installs a command-line utility named electruth. This program has many settings, and it's recommended to run electruth --help to get an overview of them.
The program creates boolean expressions from whatever input you give it. If you give it more than one input, it will compare the two inputs (unless if you tell it not to do that). Many inputs are supported:
* Basic boolean expressions (e.g. A and (B or C) or A * (B + C) (the same))
* Truthtables, using tab-separated (.tsv) or comma-separated (.csv) values in a file, the first row specifying the names of the inputs and outputs with a < prefix for inputs and a > prefix for outputs.
* Netlists (.net), e.g. those generated from gnetlist from the gEDA project (gEDA schematics from gschem can also be loaded, but they will be converted to netlists (saved in temporary files) at first).
Some settings can also be set in a config file. Config files use a property = value syntax (e.g. auto compare = false) separated by newlines.
Developing
electruth is written in Python and uses Git for branches. To get the latest branch, get it from gitorious.org like this:
