Graphviz Interactive Preview (Visual Studio Code Extension)

A VSCode extension that provides syntax highlighting, snippets, and an interactive, zoom-, pan- and searchable, live preview with edge tracing for graphs in Graphviz / dot format.

Language Features

• Graphviz/Dot Language Support / Syntax Highlighting and Snippets (thanks @joaompinto) • AutoCompletion • Rename Symbols • Find References of node IDs • Color selection via Color decoration • Hover information for settings • Shows syntax errors (only available when the preview of the document is active)

Interactivity Features

• Renders dot/Graphviz sources in an interactive live preview. • Updates preview as you type. • Search for nodes in the graph. • Export the graph as svg or dot. • Interactive edge tracing. Click on a node to highlight incoming and outgoing edges (ESC to unselect). The Direction of the highlighting can be changed (options: single, upstream, downstream, bidirectional) • Configurable render engine, render options & tracing preference: e.g. transitionDelay, transitionDuration.

Other features

• Available on github.dev, vscode.dev • Developers: you can pass a callback function that receives the webPanel when executing the preview command. This allows you to override functionality that is provided by the webPanel, like handlers for click/dblClick events.

How to preview

Open a Graphviz/Dot file in the active editor and use either of the following methods to render the preview:

• (a) open the command prompt (cmd+shift+p) and type > graphviz preview • (b) click the button in the editor title • (c) from the editor window's context menu, select Preview Graphviz / Dot (beside)

In order to test the extension as a web extension you have to start

Interact with this extension

• add graphviz-interactive-preview to your package.json extension dependencies. • Create one or multiple new panels displaying the rendered dot graph. Provide the document or uri object reference of the source code you want to render. Alternatively, you can also provide a document or uri reference of a virtual document and provide the graphviz dot source with the content field. In this case the extension will render the content and use the virtual document to extract the path information. The callback function receives the newly created webPanel. Overload webPanel.handleMessage((message) from your callback function to receive message events like onClick and onDblClick emitted from inside the dot render window.

Please do not hesitate to reach out if you are missing specific functionality.
