UPDATE May 2024 - bitbar is no longer a supported app on modern macs

also the canvas api used for graph is deprecated

Here is a simple plugin script for bitbar's replacement: https://xbarapp.com/

First install fx with brew install fx

Create a file called nightscout.50s.sh in your xbar plugins folder and add the following with YOUR_NIGHTSCOUT_URL:

#!/usr/bin/env bash
curl -s https://{YOUR_NIGHTSCOUT_URL}/pebble | /opt/homebrew/bin/fx \
   'x => ({sgv: x.bgs[0].sgv, delta: x.bgs[0].bgdelta, plusminus: x.bgs[0].bgdelta >= 0 ? `+` : ``, mins: Math.round((x.status[0].now - x.bgs[0].datetime) / 1000 / 60)})' \
   'x => ({...x, delta: `${x.plusminus}${x.delta}`, color: x.sgv < 4 ? "red" : x.sgv > 12 ? "orange" : "#eeeeee"})' \
   'x => x.mins > 15 ? `${x.mins}m  (${x.sgv}) | color=red | size=11` : `${x.sgv}  ${x.delta}  ${x.mins}m | color=${x.color}`'

Finally run command chmod +x nightscout.50s.sh and you should be good to go!

It will look like this, with red text for lows and orange for highs:

Thanks!
