VS Code / Cursor

The VS Code extension lives in nasa-core-artemis/ and ships both nasa-core-artemis-dark and nasa-core-artemis-light.

Install from source (recommended)

1. Install Node.js if you do not already have it.

2. Install the VS Code extension packaging tool:

   npm install -g @vscode/vsce

3. Package the extension from the repo root:

   cd nasa-core-artemis
   vsce package

4. Install the generated .vsix file:

   • VS Code / Cursor: open the Extensions view, open the ... menu, choose Install from VSIX..., and select nasa-core-artemis-0.0.1.vsix
   • CLI: code --install-extension .\nasa-core-artemis-0.0.1.vsix

5. Reload the editor if prompted.

Try without packaging (development)

1. Open the nasa-core-artemis folder in VS Code or Cursor.
2. Press F5 to launch an Extension Development Host window.
3. In the new window, open the color theme picker and select nasa-core-artemis-dark or nasa-core-artemis-light.

Apply the theme

1. Open the Command Palette (Ctrl+Shift+P on Windows/Linux, Cmd+Shift+P on macOS).
2. Run Preferences: Color Theme (or press Ctrl+K, then Ctrl+T).
