Block Diagrams in Python

Project description

Welcome to BDP

BDP (Block Diagrams in Python) aims to become a Python fronted for TikZ when it comes to drawing block diagrams in order to facilitate the process. BDP wraps the TikZ statements into the Python objects so that users can describe diagrams in pure Python. However, inserting raw TikZ in BDP is also possible. Figure below shows an BDP example image which represents the BDP compilation process.

Figure can be rendered with the BDP diagram. It can be rendered into the PNG with BDP via command line:

# bdp -p

For a complete list of command line options please take a look at command_line chapter of the documentation.

Why BDP?

BDP brings following benefits:

  • Diagram description in Python which should render it more readable

  • Step-by-step debugging of the diagram description

  • Use the tools and design environments available for Python development (debugging, code completion, refactoring, documentation utilities…)

  • Use vast Python library of packages

BDP features

BDP package comprises:

  • Python classes that wrap the Tikz statements

  • Class for rendering PDF and PNG images from the Python description

  • Shell entry point for rendering BDP images from command line

  • Sphinx extensions for embedding BDP images into the Sphinx documents

Image below is a more complex example, which shows how power of Python programming can be used to generate diagrams with BDP. Image shows an UML-like diagram of few major BDP templates.

Figure can be rendered with the BDP diagram.

Where to start?


BDP package currently supports only Python 3. Following are alternative ways to install BDP.

Install BDP using pip:

pip3 install bdp

Install BDP using easy_install:

easy_install3 bdp

Install BDP from source:

python3 install

BDP requires TeX Live, which could be installed on a Debian or a Debian-derived systems, with:

# sudo apt-get install texlive

For converting PDF to PNG, pdftoppm, pnmcrop and pnmtopng are needed, which could be installed on a Debian or a Debian-derived systems, with:

# sudo apt-get install poppler-utils
# sudo apt-get install netpbm
