Multiline Field in Slack Message

[dorukkangal]

I want to add a multi-line field to the slack message, but I’m having trouble with the format.
Only the first line of the Release Notes field is visible. Slack step and output is as follows:

- slack@3:
    inputs:
      - webhook_url: $SLACK_URL
      - channel: '#app-releases'
      - title: ''
      - message: ''
      - author_name: ''
      - pretext: ''
      - text: ''
      - fields: |-
          Release Notes|-Fix build issue
          -Update app icon
          App|${BITRISE_APP_TITLE}
          Workflow|${BITRISE_TRIGGERED_WORKFLOW_ID}
          Git Branch|${BITRISE_GIT_BRANCH}
          Git Author|${GIT_CLONE_COMMIT_AUTHOR_NAME}
          Git Commit|${GIT_CLONE_COMMIT_MESSAGE_SUBJECT}
          Git Commit Hash|${GIT_CLONE_COMMIT_HASH:0:7}

So I tried with ‘\n’ as below but this method doesn’t seem to work either.

- slack@3:
    inputs:
      - webhook_url: $SLACK_URL
      - channel: '#app-releases'
      - title: ''
      - message: ''
      - author_name: ''
      - pretext: ''
      - text: ''
      - fields: |-
          Release Notes|-Fix build issue\n-Update app icon
          App|${BITRISE_APP_TITLE}
          Workflow|${BITRISE_TRIGGERED_WORKFLOW_ID}
          Git Branch|${BITRISE_GIT_BRANCH}
          Git Author|${GIT_CLONE_COMMIT_AUTHOR_NAME}
          Git Commit|${GIT_CLONE_COMMIT_MESSAGE_SUBJECT}
          Git Commit Hash|${GIT_CLONE_COMMIT_HASH:0:7}

I’ve read the links below but couldn’t find the solution. What method should I use for the correct format?

Slack message formatting

Why can’t I format my slack messages? Im getting: [image] And at steps-slack-message/main.go at master · bitrise-steplib/steps-slack-message · GitHub I see that it should be enabled. So why is my text not bold, and a newlane, any clues?

Slack step does not treat "\n" as a newline when message generated by a Bash script step

script adding message to environment variable envman add --key SLACK_MESSAGE --value "foobar\nfoobar\nfoobar" message property on slack step - message: |- $SLACK_MESSAGE Build Log Slack configs: - WebhookURL: ********* - Channel: ********* - FromUsername: Bitrise CI - FromUsernameOnError: Bitrise CI - ERROR - Message: foobar\nfoobar\nfoobar Posted message foobar\nfoobar\nfoobar According to the slack documentation, I thought a \n is converted to a newline. https://api.slack.com…

Try adding ‘\n’ for new lines in the text field, the fields are single line only I believe

If you want additional text use the text field instead of the fields input

• text:
• fields:

I mentioned that I already added ‘\n’ but it’s not working. Do you mean something different?

[damien.murphy]

fields are single line and do not support “\n”
text supports multiline “\n”

[dorukkangal]

No, Slack supports multi-line fields. I tried it with Slack webhook and it works.

I ran some tests and confirmed what you observed.

Here is a PR to solve the issue, nice catch!

You can test this fork step by using this in your bitrise.yml by replacing the - slack@3: with

- git::https://github.com/DamienBitrise/steps-slack-message@master:

Here is a working example from my test where the field is

- fields: |
    App|${BITRISE_APP_TITLE}\nline 2

[dorukkangal]

It works like a charm. Thank you very much
