Requirements

  • OS X (tested with 10.8 and 10.10, may work with earlier versions)
  • A working installation of Nightscout (cgm-remote-monitor)

Installation

  1. Download this zip file containing the app and unzip it.
  2. Drag "Nightscout Menubar" into your "Applications" folder.
  3. Run it.
  4. (Optional) To run automatically on startup, go to System Preferences > Users & Groups > Login Items, and add Nightscout Menubar to the list.

Customization

For now, if you want to customize the display and are comfortable making small edits to a Python file, you can edit nightscout_osx_menubar.py within the app package.

In Finder, right-click on the app and click "Show Package Contents". Open Contents/Resources/nightscout_osx_menubar.py in a text editor. All the available configuration is at the top of the file.

For example:

  • Change HISTORY_LENGTH to control the number of history menu items
  • Change MENUBAR_TEXT to u"{sgv} {direction}" to shorten the menu bar text to only BG and a trend arrow
  • Change MENU_ITEM_TEXT to likewise change how the history items are formatted
  • Modify time_ago to return strings like "5m" instead of "5 min"
  • etc.

This is not a long-term solution since your modifications won't survive a reinstall of the app. A better configuration system is in the works.

Development

This uses rumps, which provides a nice interface to PyObjC to create simple menu bar apps, and py2app, a Python setuptools command which allows you to package Python scripts as standalone OS X applications.

To run the app in development:

git clone https://github.com/mddub/nightscout-osx-menubar
cd nightscout-osx-menubar
pip install -r requirements.txt --user  # This may take a while
python nightscout_osx_menubar.py

To build a standalone app in dist/:

python setup.py py2app

Troubleshooting

  • If an error occurs while running the standalone app, some additional information was probably logged to the Console app (in Applications > Utilities).

  • To view the app's output in the terminal and get extra debug information, start the app from the command line with the --debug flag:

    cd /Applications
    ./Nightscout\ Menubar.app/Contents/MacOS/Nightscout\ Menubar --debug
