It uses doxygen to parse code.
- Visualize call graph
- Visualize class hierarchy
- Visualize class membership
- Visualize variable usage
- Visualize folder structure
- Visualize file include graph
- Visualize project dependencies
- Quick navigation
- Save/Load graph bookmarks
- Write comments on functions/classes/variables
- Python (Not tested yet)
- PHP (PHP extension required)
- Other languages that doxygen supports
For beginners, please check out this video:
The video explains all main usages, especially the empty viewport problem reported by many users.
Here is a screenshot of the plugin.
A diamond is a class.
A disk is a function.
A triangle is a variable.
Colors for these shapes represent different classes, whose name can be seen at the top-left corner.
A "book mark label" is a code position. In the image, it's line 50 in the file "PatternDetector.h".
A white square is a file.
Colors for edges represent different graphs, whose name and key short-cut can be seen at the bottom-left corner.
Here are main features for Code Graph.
mouse wheel to zoom in and out.
right mouse button to move the view.
Move cursor onto function/class/variable name in Visual Studio Text Editor, then press
Alt+F to show it on Code Graph.
Alt+J/K/L/I in Visual Studio Text Editor to jump to neighbour items.
Find Callers/Callees/Variable Usage/Include Files
Alt+C to find callers / included files / functions using the variable.
Alt+V to find callees / files including this file / used variables.
Some callees may not be found by pressing
Alt+V. In these cases, place the cursor on those callees and press
Alt+H, then they will be added to Code Graph.
Find Overloaded Functions
Alt+O to find overloaded functions.
Find Class Member
Alt+M to find one class variable and the largest member function. Press
Alt+M several times to see more members.
Alt+U to find references. Then move to code position and press
Alt+U again to show the actual function.
Save / Load Relationship Graph
Ctrl+Num to add selected edge to a relationship graph.
Alt+Num to show relationship graph listed at the bottom left corner.
Input your comment for functions/classes/variables in Symbol panel.
Add Custom Edge
Some function call relationship can't be detected because of limited capability of doxygen. In this situation, you can create custom edge to represent missing relationship.
You can connect any item using custom edge.
To create custom edge, use
middle mouse button to drag one item to another.
- Download the vsix package or compile one yourself.
- Open and install the package.
- The package is installed.
- Open Visual Studio, you can see a new menu. Press "Open Code Graph Window" to show the window.
- Open a solution, then press "Analyse solution" to generate the code database for Code Graph.
- A command-line window appears, and you can see "Wait..." on the viewport. You can continue coding during analysis process.
- When analysis is completed, the code database will be opened automatically. Place the cursor on a variable/function/class and press
Alt+F , then the symbol will appear in the viewport.
- Next time when you open Visual Studio, you don't have to analyse the solution again, just click "Open Analysis Result" and choose a ".graph" file. The file with a "solution" postfix is the analysis result (code database) for the whole solution.
