About vscode-mermAId
[!NOTE]
Starting in VS Code 1.109 support for mermaid diagrams is built into VS Code! Therefore this extension is no longer maintained.
Description
Collaborate with GitHub Copilot to create Mermaid diagrams through the chat participant, @mermAId.
This extension was built in part to demonstrate the power of new GitHub Copilot extension APIs. Check out the VS Code Chat Participant API for more info!

Features
Ask the @mermAId chat participant to generate a diagram based on the current open editor. Include slash commands for commonly used diagram types. Follow the links in the diagram to relevant source code.

Don't have any code? Chat with @mermAId to prototype an idea or deepen your knowledge of programming concepts

Iterate on complex diagrams using natural language

Open the "Visual Outline" view to dynamically generate diagrams when swapping between editors. Break out into chat for finer control.

Export diagrams as markdown to share directly in places that render mermaid (like GitHub Issues).
