# Sticky Pull Request Comment

Create a comment on a pull request, if it exists update that comment.
This library runs with GitHub Actions. If you feel that the example grammar below is not friendly enough, we recommend reading [this page](https://docs.github.com/en/actions) first.

## Usage

### Basic

```yaml
uses: marocchino/sticky-pull-request-comment@v2
with:
  message: |
    Release ${{ github.sha }} to <https://pr-${{ github.event.number }}.example.com>
```

### Keep more than one comment

In some cases, different actions may require different comments. The header allows you to maintain comments independently.

````yaml
release:
  ...
  - uses: marocchino/sticky-pull-request-comment@v2
    with:
      header: release
      message: |
        Release ${{ github.sha }} to <https://pr-${{ github.event.number }}.example.com>

test:
  ...
  - name: Run Test
    id: test
    run: |
      OUTPUT=$(rake test)
      OUTPUT="${OUTPUT//'%'/'%25'}​【7,6 m】"
      OUTPUT="${OUTPUT//$'\n'/'%0A'}"
      OUTPUT="${OUTPUT//$'\r'/'%0D'}"
      echo "result=$OUTPUT" >> $GITHUB_OUTPUT
  - uses: marocchino/sticky-pull-request-comment@v2
    with:
      header: test
      message: |
        ```
        ${{ steps.test.outputs.result }}
        ```
````

### Append after comment every time it runs

````yaml
test:
  ...
  - name: Run Test
    id: test
    run: |
      OUTPUT=$(rake test)
      OUTPUT="${OUTPUT//'%'/'%25'}​【7,6 m】"
      OUTPUT="${OUTPUT//$'\n'/'%0A'}"
      OUTPUT="${OUTPUT//$'\r'/'%0D'}"
      echo "result=$OUTPUT" >> $GITHUB_OUTPUT
  - uses: marocchino/sticky-pull-request-comment@v2
    with:
      append: true
      message: |
        Test with ${{ github.sha }}.
        ```
        ${{ steps.test.outputs.result }}
        ```
````

### Comment from push

If for some reason, triggering on pr is not possible, you can use push.

```yaml
- uses: jwalton/gh-find-current-pr@v1
  id: finder
- uses: marocchino/sticky-pull-request-comment@v2
  with:
    number: ${{ steps.finder.outputs.pr }}
    message: |
      Test ${{ github.sha }} ended successfully.
      This message is from a push.
```

### Read comment from a file

```yaml
uses: marocchino/sticky-pull-request-comment@v2
with:
  path: path-to-comment-contents.txt
```

### Delete the previous comment and add a comment at the end

```yaml
uses: marocchino/sticky-pull-request-comment@v2
with:
  recreate: true
  message: |
    Release ${{ github.sha }} to <https://pr-${{ github.event.number }}.example.com>
```

### Delete previous comment

```yaml
uses: marocchino/sticky-pull-request-comment@v2
with:
  header: <same-header-as-the-step-that-added-the-comment>
  delete: true
```

### Hide the previous comment and add a comment at the end

```yaml
uses: marocchino/sticky-pull-request-comment@v2
with:
  hide_and_recreate: true
  hide_classify: "OUTDATED"
  message: |
    Release ${{ github.sha }} to <https://pr-${{ github.event.number }}.example.com>
```

### Hide previous comment

```yaml
uses: marocchino/sticky-pull-request-comment@v2
with:
  header: <same-header-as-the-step-that-added-the-comment>
  hide: true
  hide_classify: "OUTDATED"
```
