LoopFollow

Purpose:

Using so many different apps as a parent or caregiver of a T1D can be very cumbersome. Add in the extra details from looping with an Open Source Automated Insulin Delivery app and it can be a challenge flipping back and forth between apps. Each app has different strengths and weaknesses. LoopFollow melds together some needs into one app.

An example of the main screen for LoopFollow is shown in the graphic below:

Building Options

Please see Loop and Learn: LoopFollow for all the building options.

With the release of version 2.1.0, there is now an easy option for building up to three instances of the LoopFollow app for multiple Loopers in your family. Each instance can be configured to have the display name you choose with these names being the default:

• LoopFollow
• LoopFollow_Second
• LoopFollow_Third

Display Name Updates

The display_name is found in a single file.

• Suggestion if you customize the name: use LF {unique name} so you can find the apps easily in iOS Settings screen

Summary instructions by build method:

• Browser Build:
  • Fork and setup the repository for each LoopFollow instance you want to use:
    • https://github.com/loopandlearn/LoopFollow
    • https://github.com/loopandlearn/LoopFollow_Second
    • https://github.com/loopandlearn/LoopFollow_Third
  • Commit the desired display_name in the LoopFollowDisplayNameConfig.xcconfig file of your forked repository for LoopFollow, LoopFollow_Second or LoopFollow_Third
• Mac-Xcode Build
  • First build with script, you will be prompted to enter the desired display_name
  • This display_name is used each time you select a fresh download for LoopFollow 1, 2 or 3
  • To modify the display_name for subsequent script builds, edit the appropriate file in the ~/Downloads/BuildLoopFollow folder
    • LoopFollowDisplayNameConfig.xcconfig
    • LoopFollowDisplayNameConfig_Second.xcconfig
    • LoopFollowDisplayNameConfig_Third.xcconfig

Updates

When modifications and versions are updated, you might see activity at GitHub. Please wait for the release message to be posted at LoopFollow Releases before using the updated versions for the main branch of LoopFollow, LoopFollow_Second and LoopFollow_Third.

Version Numbers

Updates to the main branch (releases) have a version number that ends in 0; for example, 2.7.0.

• Immediately following the release, the dev branch is at the same version as main indicating the code is identical
• Each time a feature is merged into the dev branch, the final number increments; for example, 2.7.1, 2.7.2
• When the next release is made, the second digit is incremented and the final digit is restore to 0 for both main and dev; for example, 2.8.0

General feature list

Please review the list on Loop and Learn: LoopFollow.

Each time a release is made, the features added or bugs fixed for that particular release are found at LoopFollow Releases.

Open Source DIY

This is a DIY open source project that may or may not function as you expect. You take full responsibility for building and running this app and do so at your own risk.

For Developers

• If you are interested in assisting with this app and want to work on new features and improvements for Loop, Trio, iAPS and Nightscout functionality, please reach out.
• Issues and Pull Requests in GitHub are monitored and will get a response.

New PR are directed to the dev branch. If you direct one to main, we will move it to point to dev. So always start with your code aligned with dev.

Always rename your branch (that is aligned with dev) to a name suitable for your feature, for example, feature_name, before starting to add commits to your branch.

After a PR is merged to dev, there is an automatic bump up the version number - please do not modify the version in your branch.

Version Updates

Only the maintainers for LoopFollow will update version numbers.

Release Process

To assist in releasing to all three LoopFollow repositories, the script release.sh is now available. This bumps up the version number to M.N+1.0 for a minor release or M+1.0.0 for a major release. It also updates the LoopFollow_Second and LoopFollow_Third repositories with parallel changes to what was just released for LoopFollow. Only LoopFollow uses a dev branch. The other repositories use just the main branch and are kept at the released version.

When a release is generated, the updates found in the dev branch are merged into main; the version number in the Config.xcconfig file is updated to A.B.O; a tag of the form v.A.B.0 is created and associated with the main branch at that time.

When PR are subsequently merged to dev, the version number is incremented by 1 in the last place, e.g., "v.A.B.1" etc.

Files in LoopFollow Only

There are several files found only in the LoopFollow repository:

• .github/workflow/auto_version_dev.yml
• release.sh

These files are not added to _Second or _Third version because they are not needed for those repositories.
