Question: how to set the reviewers as assignees?

[ebramirez]

Is it possible to reuse the current PR reviewers value as the assignees of an Action run?

The use case would be when the author of the PR pushes more commits as a result of a review, the assignment returns to the reviewers. Example:

on:
  pull_request:
    types: [synchronized]

jobs:
  assign:
    runs-on: ubuntu-latest
    steps:
      - uses: hkusu/review-assign-action@v1
        with:
          assignees: ${{ github.event.pull_request.reviewers ??? }}

[hkusu]

For the same as #15, it is not possible, because this Action can only set the assignee when the pull request is opened.

In the same way, I think you can use the GitHub CLI to do something like:

- run: |
    reviewersJson='${{ toJson(github.event.pull_request.requested_reviewers.*.login) }}'
    reviewers=$(echo $reviewersJson | jq -r '.[]')
    reviewers=$(echo $reviewers) # remove newline
    reviewers=${reviewers// /,} # spaces to commas
    gh pr edit ${{ github.event.number }} --add-assignee $reviewers --repo ${{ github.repository }}
  env:
    GITHUB_TOKEN: ${{ github.token }}
