Scriptable is an app that has similar functionality to Apple Shortcuts, but uses JavaScript.
To use these scripts:
- Install Scriptable from the app store
- Create a new script, call it RepoManager
- Copy and paste RepoManager.js (from this repo) into the script you made
- Run it and select "install all" or select a script you want and then "install"
- Check bookmarks.js for more info on setup
