vscode extension for generate call graph in graphviz dot language, based on vscode call hierarchy language feature.
Features
Generate call graph in graphviz dot language and preview
Generate sequence diagrams using Mermaid syntax
Generate class diagrams using Mermaid syntax
Save graph as dot or svg file
Export sequence and class diagrams as SVG or download source code
Intelligent filtering of high in-degree nodes to reduce diagram complexity
Accurate representation of actual call sequence in sequence diagrams
Language-agnostic class detection for class diagrams (supports C++, Go, TypeScript, and more)
Quick start
Open your folder and select a entry function
Run CallGraph.showOutgoingCallGraph command using context menu or Ctrl+Shift+P to show outgoing calls
Or Run CallGraph.showIncomingCallGraph command using context menu or Ctrl+Shift+P to show incoming calls
For sequence diagrams, use CallGraph.showOutgoingSequenceDiagram or CallGraph.showIncomingSequenceDiagram
For class diagrams, use CallGraph.showOutgoingClassDiagram or CallGraph.showIncomingClassDiagram
Click save dot file or save as svg in the bottom left corner to save the graph
For sequence and class diagrams, use the "Export SVG" or "Download Source Code" buttons
Add .callgraphignore file in your project root directory to ignore some files or folders in workspace (the syntax is the same as .gitignore)
Configuration
You can configure ignoreFile(.callgraphignore by default), maxDepth, and inDegreeThreshold. See the descriptions in setting.
ignoreFile: Path to the file that specifies paths to ignore (default: ${workspace}/.callgraphignore)
maxDepth: The maximum depth of the call graph (default: 0, which means unlimited)
inDegreeThreshold: Filter nodes with in-degree greater than this threshold in incoming call graphs (default: 5)
Recent Updates
Class Diagrams
Added support for generating class diagrams using Mermaid syntax
Class diagrams show relationships between classes based on function calls
Only displays methods that are called by other classes for cleaner diagrams
Language-agnostic implementation that works with multiple programming languages
Export class diagrams as SVG or download the Mermaid source code
Sequence Diagrams
Added support for generating sequence diagrams using Mermaid syntax
Sequence diagrams now accurately reflect the actual call order in your code
Export sequence diagrams as SVG or download the Mermaid source code
Node Filtering
Improved filtering of high in-degree nodes to reduce diagram complexity
Configurable threshold via the inDegreeThreshold setting
UI Improvements
Enhanced zoom and pan controls for better diagram navigation
Added export functionality for both call graphs and sequence diagrams
How it works
It depends vscode.provideOutgoingCalls and vscode.provideIncomingCalls built-in commands( the same with Show Call Hierarchy command, not available for some language server ).
