This page describes how to procure your very own, shiny copy of PyEDA. It is a primary goal of the PyEDA project to be a mainstream Python package, and adhere to the majority of conventions observed by the community.
PyEDA supports Windows, and any platform with a C compiler. The author does development and testing on MacOS and Ubuntu Linux.
Supported Python Versions¶
Starting with version 0.15, PyEDA will only work with Python 3.2+. Starting with version 0.23, PyEDA will only work with Python 3.3+. There were several reasons to drop support for Python 2:
- Python 3 is the future of the language.
- Almost all scientific software either has already been ported, or is in the process of being ported to Python 3.
- Only Python 3 has support for the def f(*args, kw1=val1, ...) syntax, used to great effect by logic expression factory functions.
- It is too arduous to research and support all the C API changes from version 2 to version 3. Preprocessor is evil.
- I am quite fond of the new yield from ... syntax.
Distutils / Virtualenv¶
The latest PyEDA release is hosted on PyPI.
To get PyEDA with pip:
$ pip3 install pyeda
We strongly recommend that you also install an excellent Python tool called IPython. For interactive use, it is vastly superior to using the standard Python interpreter. To install IPython into your virtual environment:
$ pip3 install ipython
If you are using the Linux system distribution of pip, most likely pip will be part of Python-2.x, which won’t work. It’s safer to always use pip3.
You will probably need to install the Python3 “development” package to get Python’s headers and libraries. For Debian derivatives (eg Ubuntu), run sudo apt-get install python3-dev. On RedHat derivatives, run sudo yum install python3-devel.
I highly recommend Christophe Gohlke’s pythonlibs page for installing PyEDA on Windows.
If you are using a Windows wheel distribution, you may need to install the [Visual Studio 2012 Redistributable](http://www.microsoft.com/en-us/download/details.aspx?id=30679).
Getting the Source¶
The PyEDA repository is hosted on GitHub. If you want the bleeding-edge source code, here is how to get it:
$ git clone https://github.com/cjdrake/pyeda.git $ cd pyeda # $PREFIX is the root of the installation area $ python setup.py install --prefix $PREFIX
If you want to build the documentation, you must have the excellent Sphinx documentaton system installed.
$ make html
If you want to run the tests, you must have the excellent Nose unit testing framework installed.
