pull-detached-remote

Warning: Deprecated
This action is deprecated and can easily be replaced by a simpler alternative workflow

Creates a branch with updates from a detached (not actively set) upstream of a repo and a corresponding PullRequest

If you don't understand the quick summary read the following:

Why?

This action was mainly created for the following use-case:

You have a GitHub repo that is not directly linked via an upstream-remote This can be achieved by

duplicating a repo or
forking a repo and removing it's upstream remote

Now you wan't to update this repo from it's "upstream" (which is not actively set / detached).
You can do that manually, but after some time (especially when there are more often commits on the "upstream"), you definetly wan't to do that automated.

An here this action comes into spotlight.

It automatically updates your "detached upstream":
Firstly it checks if there are new commits on the upstream.
When there are new ones, it creates a new branch and a pull request.

The action is based on PullDetachedRemote
