A simple package allowing to use WebGraph data in Python (using the Jython interpreter).
The code in this project is based on
- WebGraph 3.6.5
- Python 2.7.16
- Jython 2.7.2
- Ubigraph 0.2.4alpha no more available
and has been tested on Mac OS X 10.13.6.
For details, please refer to the documentation.
Installation hint
To install the required jars run ./install_jars.sh (it basically downloads the
binary tarball and dependencies tarball tarballs from the
WebGraph site and unpacks all the jars in the
jars directory); observe that the script refers to version 3.6.5 of WebGraph, in case of version changes just update the relevant line of the script.
Then create an example.graph-txt file containing a test graph (as per ASCIIGraph format), for instance
3
0 1 2
2
0
Now, running Jython as jython -J-cp 'jars/*' should work as follows
Jython 2.7.2 (v2.7.2:925a3cc3b49d, Mar 21 2020, 10:03:58)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java11.0.5

Note the -J-cp 'jars/*' that sets the classpath to the directory where the jars have been unpacked.
