"""This script is used in GitHub Actions to determine what boards are built
|
||
|
|
based on what files were changed. The base commit varies depending on the
|
||
|
|
event that triggered run. Pull request runs will compare to the base branch
|
||
|
|
while pushes will compare to the current ref. We override this for the
|
||
|
|
adafruit/circuitpython repo so we build all boards for pushes.
