Create a new GraphPrinter plugin that prints IElement data structures
(AST, CFG, interpolant automata, etc.) in DOT (Graphviz) format to files.
The plugin works like JungVisualization but is headless (isGuiRequired()
returns false), making it usable in both GUI and CLI modes.
The plugin uses the same IVisualizable -> VisualizationNode -> DFS traversal
pattern as JungVisualization, but writes DOT output to a file instead of
displaying in a JUNG viewer. Node labels use the full object's toString()
without truncation.
Preferences follow Ultimate's well-known dump pattern:
- Graph directory (default: current directory)
- Graph filename (default: "graph")
- Write graph besides input file (default: true)
- Which models to print (default: LAST, configurable like JungVisualization)
An annotation output mode controls how metadata and annotations from
VisualizationNode and VisualizationEdge payloads are included in the DOT
output:
- NONE: no annotations in the output (like before)
- HTML_LABELS: annotations are embedded as DOT HTML-like labels on nodes
and edges, showing the label followed by an HTML table of
all annotation key-value pairs (default mode)
- RECORD_NODES: annotations are rendered as separate record nodes
connected to their parent node/edge with dashed edges
