export_graphml.py

Version: 1.4.0 Runs in: Command line (outside Hopper)

Purpose

Converts a Hopper callgraph JSON export (*.callgraph.json) into GraphML format for use with external graph analysis tools such as Gephi, yEd, or Cytoscape.

Output

A .graphml file containing the call graph as a directed graph with named nodes.

Behavior

  • Nodes include a name data attribute from the callgraph export.
  • Edges are deduplicated by (source, target) pair.
  • Nodes referenced in edges but missing from the node list are auto-created without a name attribute.
  • All IDs and names are XML-escaped.

Usage

python export_graphml.py <callgraph.json> <output.graphml>

Arguments

Argument Required Description
input_json yes Path to *.callgraph.json
output_graphml yes Destination GraphML file path

Example

python export_graphml.py myapp.callgraph.json myapp.graphml

Output format

<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns">
  <key id="name" for="node" attr.name="name" attr.type="string"/>
  <graph id="G" edgedefault="directed">
    <node id="0x1000"><data key="name">main</data></node>
    <edge source="0x1000" target="0x2000"/>
  </graph>
</graphml>
