Small script that gets the current temp from the Dark Sky API, for displaying with Better Touch Tool. Requires a developer account + API secret from Dark Sky
After building the script, you can execute it in BTT by adding a new TouchBar widget to "Run Shell Script and Show Return Value", and adding the following:
export DARK_SKIES_API_SECRET= {your api secret}
