LARA Visualization Tool

Web tool for visualization and analysis of the AST and its source code.

Integration

Internally, the tool follows a system for interaction with the compiler, to be able to apply code linkage and correction, among others, while still being independent of the specific compiler. This system is an implementation of the Factory Method pattern, and the integration with Clava is illustrated in the following diagram:

To integrate the tool in another compiler:

1. Implement the GenericAstConverter interface, with its functions properly implemented. More information can be found in their documentation.
2. Create a class that extends GenericVisualizationTool, and override getAstConverter so that it returns an instance of the class declared in the previous step.
3. Use an instance of the previous class as the entry point of the visualization tool API, for the compiler in question.

Usage

The tool is best suited to be extended as a new NPM package. For integration, create a new NPM project and include LARA Visualization Tool's package.

npm install @specs-feup/lara-visualization

From there, make all adjustments necessary to use the tool for your compiler in that package, and include it in the project where your LARA scripts are found.

After integration, and being VisualizationTool the extended derived class of GenericVisualizationTool, to launch or update the visualization tool, execute the following statement:

await VisualizationTool.visualize();

Once ready, the tool will provide the URL that should be opened in the browser to access the web interface. The function can also change the AST root and URL domain and port.

Other properties will allow the user to know other important information from the server:

VisualizationTool.isLaunched;  // true if the server is running
VisualizationTool.url;         // URL where the server is running
VisualizationTool.port;        // port to which the server is listening
VisualizationTool.hostname;    // hostname to which the server is listening
