Features

• Use GitHub Copilot in the Obsidian editor

• Configure if you want to see suggestion only in code blocks or in the whole note

Known issues

• If you installed Obsidian with Flatpak, you might need to use NVM to handle Node.js versions as the default binary path is not accessible in the Flatpak sandbox. See this issue for more information.
• "Tab" completion can be buggy in some cases (e.g. in bullet points in LateX Math mode for example). It depends on plugin priority over the keybindings. See this issue for more information.

Mermaid Diagrams

The chat supports rendering Mermaid diagrams when GitHub Copilot responds with Mermaid code blocks. Simply ask Copilot to create a diagram and it will render visually in the chat.

Example usage:

You: Can you create a flowchart showing the software development lifecycle?

Copilot: Here's a flowchart of the software development lifecycle:

```mermaid
flowchart TD
    A[Requirements Analysis] --> B[Design]
    B --> C[Implementation]
    C --> D[Testing]
    D --> E[Deployment]
    E --> F[Maintenance]
    F --> A

Supported diagram types:

• Flowcharts
• Sequence diagrams
• Class diagrams
• State diagrams
• Gantt charts
• Pie charts
• And more...

The diagrams automatically adapt to your Obsidian theme (light/dark mode) and are fully integrated into the chat interface.
