Provide a 'commit-message-body' field? about create-pull-request HOT 3 CLOSED

@hwhsu1231 Sorry, I misunderstood what you were trying to do.

You can handle multiline content from a file into a step variable like this.

      - id: get-commit-message
        run: |
          body=$(cat commit-message.txt)
          delimiter="$(openssl rand -hex 8)"
          echo "body<<$delimiter" >> $GITHUB_OUTPUT
          echo "$body" >> $GITHUB_OUTPUT
          echo "$delimiter" >> $GITHUB_OUTPUT

      - name: Create Pull Request
        uses: peter-evans/create-pull-request@v4
        with:
          body: ${{ steps.get-commit-message.outputs.body }}

Just make sure you format the commit-message.txt file correctly. The first line is the "title," then leave one blank line before the "description."

commit message title

commit message body which can be multiline
another line
Some JSON:
{
  "test": "test",
  "test2": "test2"
}

from create-pull-request.

Hi @hwhsu1231

The commit-message input works the same as it does in git. If you leave a blank line after the message, anything else will populate the commit message description.

e.g.

          commit-message: |
            Add report file

            This is a test commit message body.
            You can use multiple lines.
            Some JSON:
            {
              "test": "test",
              "test2": "test2"
            }

Hope that helps you with what you are trying to do.

Hello, @peter-evans

That's not what I want! According to the demo you provided:

          commit-message: |
            Add report file

            This is a test commit message body.
            You can use multiple lines.
            Some JSON:
            {
              "test": "test",
              "test2": "test2"
            }

That means the JSON content will be hardcoded into the commit message whenver the PR is created by this GitHub Workflow.

However, in my consideration, the content of source.json will be updated continuously. Or should I say source.json file will be updated due to this GitHub Workflow is triggered.

That's why I need to extract some information from source.json file and record them into the commit message of the PR.
