6 years ago It seems there is a problem in the documentation: When you use the the id (not the _key value), you should not pass the -P flag. Without the flag, there occurs another issue: File "...local/lib/python3.5/site-packages/octopus/shelltool/ResultProcessor.py", line 16, in properties return self.result['properties'] KeyError: 'properties'
To fix this, just remove the ['properties'] in line 16 of ResultProcessor.py. Rebuild your project and it will work.
Hello! I'll preface this by saying that I'm not quite sure if this is an issue or me not fully understanding how to make best use of joern. So let's say that I have a vertex like this:
{'id': 243204216, 'label': 'vertex', 'type': 'vertex', 'properties': {'code': [{'id': '35cu1b-40spko-3yd', 'value': 'main'}], 'location': [{'id': '35cufj-40spko-27t1', 'value': '131:0:5973:6992'}], '_key': [{'id': '35ct8v-40spko-sl', 'value': '297308'}], 'type': [{'id': '35ctn3-40spko-1l1', 'value': 'Function'}]}}
And I'm interested in plotting any edges that flow out from that node, of which there are many. I've noticed that when I pass joern-plot-proggraph the id, I always get back an empty graph.
echo 243204216 | joern-plot-proggraph mycode.tar.gz -all -P //243204216 digraph "" { } //###
On the other hand, I can use Gremlin queries to trace my way from that starting vertex to all its descendants, so I would expect the dot file to be... not empty. Maybe I'm just using the tool in the wrong way.
Thanks!
P.S. (Bonus question): If I use joern in an academic paper, and I wanted to heap glowing praise on the tool and its authors, are there any works that I should cite?
