About _xdot.py_ ================= _xdot.py_ is an interactive viewer for graphs written in [Graphviz](http://www.graphviz.org/)'s [dot language](http://www.graphviz.org/doc/info/lang.html). It uses internally the GraphViz's [xdot output format](http://www.graphviz.org/doc/info/output.html#d:xdot) as an intermediate format, [Python GTK bindings](https://pygobject.readthedocs.io), and [Cairo](https://cairographics.org/) for rendering. _xdot.py_ can be used either as a standalone application from command line, or as a library embedded in your Python application. Status ====== _xdot.py_ script became much more popular than I ever anticipated, and there are several interested in improving it further. However, for several years now, _xdot.py_ already meets my own needs, and unfortunately I don't have much time for maintaining it myself. So I'm looking into transition _xdot.py_ maintenance to [others](https://github.com/jrfonseca/xdot.py/wiki/Forks): either hand over the maintenance _xdot.py_ to a community or indicate an official fork of _xdot.py_. I encourage people interested in development of _xdot.py_ to fork the [GitHub repository](https://github.com/jrfonseca/xdot.py), and join the new [mailing list](https://groups.google.com/d/forum/xdot-py). Features ======== * Since it doesn't use bitmaps it is fast and has a small memory footprint. * Arbitrary zoom. * Keyboard/mouse navigation. * Supports events on the nodes with URLs. * Animated jumping between nodes. * Highlights node/edge under mouse. Known Issues ============ * Not all xdot attributes are supported or correctly rendered yet. It works well for my applications but YMMV. * Text doesn't scale properly to large sizes if font hinting is enabled. I haven't found a reliable way to disable font hinting during rendering yet.

When running _xdot.py_ from its source tree, you can run it by first setting `PYTHONPATH` environment variable to the full path of _xdot.py_'s source tree, then running: python3 -m xdot You can also pass the following options: Usage: xdot.py [file|-] Options: -h, --help show this help message and exit -f FILTER, --filter=FILTER graphviz filter: dot, neato, twopi, circo, or fdp [default: dot] -n, --no-filter assume input is already filtered into xdot format (use e.g. dot -Txdot) -g GEOMETRY default window size in form WxH Shortcuts: Up, Down, Left, Right scroll PageUp, +, = zoom in PageDown, - zoom out R reload dot file F find Q quit P print T toggle toolbar W zoom to fit Escape halt animation Ctrl-drag zoom in/out Shift-drag zooms an area If `-` is given as input file then _xdot.py_ will read the dot graph from the standard input. Embedding --------- See included `sample.py` script for an example of how to embedded _xdot.py_ into another application.
