Personal Access Token (PAT) that allows the stale workflow to authenticate and perform API calls to GitHub.
Under the hood, it uses the [@actions/github](https://www.npmjs.com/package/@actions/github) package.
Default value: `${{ github.token }}`
#### days-before-stale
The idle number of days before marking the issues or the pull requests as stale (by adding a label).
The issues or the pull requests will be marked as stale if the last update (based on [GitHub issue](https://docs.github.com/en/rest/reference/issues) field `updated_at`) is older than the idle number of days.
If set to a negative number like `-1`, no issues or pull requests will be marked as stale automatically.
In that case, you can still add the stale label manually to mark as stale.
The label used to stale is defined by these two options:
- [stale-issue-label](#stale-issue-label)
- [stale-pr-label](#stale-pr-label)
A comment can also be added to notify about the stale and is defined by these two options:
- [stale-issue-message](#stale-issue-message)
- [stale-pr-message](#stale-pr-message)
You can fine tune which issues or pull requests should be marked as stale based on the milestones, the assignees, the creation date and the missing/present labels from these options:
- [exempt-issue-labels](#exempt-issue-labels)
- [exempt-pr-labels](#exempt-pr-labels)
- [only-labels](#only-labels)
- [any-of-labels](#any-of-labels)
- [start-date](#start-date)
- [exempt-milestones](#exempt-milestones)
- [exempt-all-milestones](#exempt-all-milestones)
- [exempt-assignees](#exempt-assignees)
- [exempt-all-assignees](#exempt-all-assignees)
Default value: `60`
#### days-before-issue-stale
Useful to override [days-before-stale](#days-before-stale) but only for the idle number of days before marking the issues as stale.
Default value: unset
#### days-before-pr-stale
Useful to override [days-before-stale](#days-before-stale) but only for the idle number of days before marking the pull requests as stale.
Default value: unset
#### days-before-close
The idle number of days before closing the stale issues or the stale pull requests (due to the stale label).
The issues or the pull requests will be closed if the last update (based on [GitHub issue](https://docs.github.com/en/rest/reference/issues) field `updated_at`) is older than the idle number of days.
Since adding the stale label will alter the last update date, we can calculate the number of days from this date.
If set to a negative number like `-1`, the issues or the pull requests will never be closed automatically.
The label used to stale is defined by these two options:
- [stale-issue-label](#stale-issue-label)
- [stale-pr-label](#stale-pr-label)
Default value: `7`
#### days-before-issue-close
Override [days-before-close](#days-before-close) but only for the idle number of days before closing the stale issues.
Default value: unset
#### days-before-pr-close
Override [days-before-close](#days-before-close) but only for the idle number of days before closing the stale pull requests.
Default value: unset
#### stale-issue-message
The message that will be added as a comment to the issues when the stale workflow marks it automatically as stale with a label.
These operations are made in a very short period of time — because the action is very fast to run — and can be numerous based on your project action configuration and the quantity of issues and pull requests within it.
GitHub has a [rate limit](https://docs.github.com/en/rest/overview/resources-in-the-rest-api#rate-limiting) and if reached will block these API calls for one hour (or API calls from other actions using the same user (a.k.a.: the github-token from the [repo-token](#repo-token) option)).
This option helps you to stay within the GitHub rate limits, as you can use this option to limit the number of operations for a single run.
_Purpose:_
This option aims 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).
If you are not sure which is the right value for you or if the default value is good enough, you could enable the logs and look at the end of the stale action.
If you reached the limit, you will see a warning message in the logs, telling you that you should increase the number of operations.
Automatically remove the stale label when the issues or the pull requests are updated (based on [GitHub issue](https://docs.github.com/en/rest/reference/issues) field `updated_at`) or commented.
Default value: `true`
#### remove-issue-stale-when-updated
Override [remove-stale-when-updated](#remove-stale-when-updated) but only to automatically remove the stale label when the issues are updated (based on [GitHub issue](https://docs.github.com/en/rest/reference/issues) field `updated_at`) or commented.
Default value: unset
#### remove-pr-stale-when-updated
Override [remove-stale-when-updated](#remove-stale-when-updated) but only to automatically remove the stale label when the pull requests are updated (based on [GitHub issue](https://docs.github.com/en/rest/reference/issues) field `updated_at`) or commented.
Default value: unset
#### debug-only
Run the stale workflow as dry-run.
No GitHub API calls that can alter your issues and pull requests will happen.
Useful to debug or when you want to configure the stale workflow safely.
Default value: `false`
#### ascending
Change the order used to fetch the issues and pull requests from GitHub:
-`true` is for ascending.
-`false` is for descending.
It can be useful if your repository is processing so many issues and pull requests that you reach the [operations-per-run](#operations-per-run) limit.
Based on the order, you could prefer to focus on the new content or on the old content of your repository.
Default value: `false`
#### start-date
The start date is used to ignore the issues and pull requests created before the start date.
Particularly useful when you wish to add this stale workflow on an existing repository and only wish to stale the new issues and pull requests.
If set, the date must be formatted following the `ISO 8601` or `RFC 2822` standard.
Default value: unset
#### delete-branch
If set to `true`, the stale workflow will automatically delete the GitHub branches related to the pull requests automatically closed by the stale workflow.
Default value: `false`
#### exempt-milestones
A white-list of milestone(s) to only process the issues or the pull requests that does not contain one of these milestone(s).
It can be a comma separated list of milestones (e.g: `V1,next`).
If unset (or an empty string), this option will not alter the stale workflow.
Default value: unset
#### exempt-issue-milestones
Override [exempt-milestones](#exempt-milestones) but only to process the issues that does not contain one of these milestone(s).
Default value: unset
#### exempt-pr-milestones
Override [exempt-milestones](#exempt-milestones) but only to process the pull requests that does not contain one of these milestone(s).
Default value: unset
#### exempt-all-milestones
If set to `true`, the issues or the pull requests with a milestone will not be marked as stale automatically.
Priority over [exempt-milestones](#exempt-milestones).
Default value: `false`
#### exempt-all-issue-milestones
Override [exempt-all-milestones](#exempt-all-milestones) but only to exempt the issues with a milestone to be marked as stale automatically.
Default value: unset
#### exempt-all-pr-milestones
Override [exempt-all-milestones](#exempt-all-milestones) but only to exempt the pull requests with a milestone to be marked as stale automatically.
Default value: unset
#### exempt-assignees
An allow-list of assignee(s) to only process the issues or the pull requests that does not contain one of these assignee(s).
It can be a comma separated list of assignees (e.g: `marco,polo`).
If unset (or an empty string), this option will not alter the stale workflow.
Default value: unset
#### exempt-issue-assignees
Override [exempt-assignees](#exempt-assignees) but only to process the issues that does not contain one of these assignee(s).
Default value: unset
#### exempt-pr-assignees
Override [exempt-assignees](#exempt-assignees) but only to process the pull requests that does not contain one of these assignee(s).
Default value: unset
#### exempt-all-assignees
If set to `true`, the issues or the pull requests with an assignee will not be marked as stale automatically.
Priority over [exempt-assignees](#exempt-assignees).
Default value: `false`
#### exempt-all-issue-assignees
Override [exempt-all-assignees](#exempt-all-assignees) but only to exempt the issues with an assignee to be marked as stale automatically.
Default value: unset
#### exempt-all-pr-assignees
Override [exempt-all-assignees](#exempt-all-assignees) but only to exempt the pull requests with an assignee to be marked as stale automatically.
Default value: unset
#### enable-statistics
Collects and display statistics at the end of the stale workflow logs to get a summary of what happened during the run.
This option is only useful if the debug output secret `ACTIONS_STEP_DEBUG` is set to `true` in your repository to display the logs.
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-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.'
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.
