### Detailed options

#### operations-per-run

Used to limit the number of operations made with the GitHub API to avoid reaching the [rate limit](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting).  
Based on your project, your GitHub business plan and the date of the cron job you set for this action, you can increase this limit to a higher number.

When [debugging](#Debugging), you can set it to a much higher number like `1000` since there will be fewer operations made with the GitHub API.  
Only the actor and the batch of issues (100 per batch) will consume the operations.

Default value: `30`

### Usage

See also [action.yml](./action.yml) for a comprehensive list of all the options.

Basic:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          stale-issue-message: 'Message to comment on stale issues. If none provided, will not mark issues stale'
          stale-pr-message: 'Message to comment on stale PRs. If none provided, will not mark PRs stale'
```

Configure stale timeouts:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          stale-issue-message: 'This issue is stale because it has been open 30 days with no activity. Remove stale label or comment or this will be closed in 5 days.'
          days-before-stale: 30
          days-before-close: 5
```

Configure different stale timeouts but never close a PR:

```yaml
name: 'Close stale issues and PR'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}
          stale-issue-message: 'This issue is stale because it has been open 30 days with no activity. Remove stale label or comment or this will be closed in 5 days.'
          stale-pr-message: 'This PR is stale because it has been open 45 days with no activity. Remove stale label or comment or this will be closed in 10 days.'
          close-issue-message: 'This issue was closed because it has been stalled for 5 days with no activity.'
          days-before-stale: 30
          days-before-close: 5
          days-before-pr-close: -1
```

Configure different stale timeouts:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          repo-token: ${{ secrets.GITHUB_TOKEN }}
          stale-issue-message: 'This issue is stale because it has been open 30 days with no activity. Remove stale label or comment or this will be closed in 5 days.'
          stale-pr-message: 'This PR is stale because it has been open 45 days with no activity. Remove stale label or comment or this will be closed in 10 days.'
          close-issue-message: 'This issue was closed because it has been stalled for 5 days with no activity.'
          close-pr-message: 'This PR was closed because it has been stalled for 10 days with no activity.'
          days-before-issue-stale: 30
          days-before-pr-stale: 45
          days-before-issue-close: 5
          days-before-pr-close: 10
```

Configure labels:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          stale-issue-message: 'Stale issue message'
          stale-pr-message: 'Stale pull request message'
          stale-issue-label: 'no-issue-activity'
          exempt-issue-labels: 'awaiting-approval,work-in-progress'
          stale-pr-label: 'no-pr-activity'
          exempt-pr-labels: 'awaiting-approval,work-in-progress'
          only-labels: 'awaiting-feedback,awaiting-answers'
```

Configure the stale action to only stale issue/PR created after the 18th april 2020:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          start-date: '2020-18-04T00:00:00Z' // ISO 8601 or RFC 2822
```

Avoid stale for specific milestones:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          exempt-issue-milestones: 'future,alpha,beta'
          exempt-pr-milestones: 'bugfix,improvement'
```

Avoid stale for all PR with milestones:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          exempt-all-pr-milestones: true
```

Check stale for specific labels:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          any-of-labels: 'needs-more-info,needs-demo'
          # You can opt for 'only-labels' instead if your use-case requires all labels
          # to be present in the issue/PR
```

Avoid stale for specific assignees:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          exempt-issue-assignees: 'marco,polo'
          exempt-pr-assignees: 'marco'
```

Avoid stale for all PR with assignees:

```yaml
name: 'Close stale issues and PRs'
on:
  schedule:
    - cron: '30 1 * * *'

jobs:
  stale:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/stale@v3
        with:
          exempt-all-pr-assignees: true
```

### Debugging

**Logs:**  
To see the debug output from this action, you must set the secret `ACTIONS_STEP_DEBUG` to `true` in your repository.  
There is a lot of logs so this can be very helpful!

**Statistics:**  
If the logs are enabled, you can also enable the statistics log which will be visible at the end of the logs once all issues were processed.  
This is very helpful to have a quick understanding of the whole stale workflow.  
Set `enable-statistics` to `true` in your workflow configuration file.

**Dry-run:**  
You can run this action in debug only mode (no actions will be taken on your issues and pull requests) by passing `debug-only` to `true` as an argument to the action.

**More operations:**  
You can increase the maximum number of operations per run by passing `operations-per-run` to `1000` for example which will help you to handle more operations in a single stale workflow run.  
If the `debug-only` option is enabled, this is very helpful because the workflow will (almost) never reach the GitHub API rate, and you will be able to deep-dive into the logs.

**Job frequency:**  
You could change the cron job frequency in the stale workflow to run the stale workflow more often.  
Usually this is not very helpful though.
