PR Updater

Quick start

1. Create user token in user settings

2. Set this token as a secret USER_TOKEN in settings of a target repository: https://github.com/<owner>/<repo>/settings/secrets

3. create file .github/workflows/pr-updater.yml with the following content:

   name: PR update
   
   on:
       push:
           branches: 
               - master
   
   jobs:
       autoupdate:
           runs-on: ubuntu-latest
           steps:
           - uses: actions/checkout@v1
           - name: update all prs
               uses: maxkomarychev/pr-updater-action@v1.0.0
               with:
                   token: ${{ secrets.USER_TOKEN }}

4. Now every time code is pushed to branches specified in the workflow all other pull requests targeting these branches will be automatically updated.

Current limitations

1. Due to rate limiting user token can only perform 5000 requests per hour
2. The action currently does not implement paging, so it can only update up to 100 pull requests in one run
