Multiline messages not working

As per the slack message formatting guide, we can insert a newline by including the characters \n. But this seems to doesn’t work in this plugin because I’m getting \n in the message.

Action - https://github.com/vineetchoudhary/AppBox-iOSAppsWirelessInstallation/blob/master/.github/main.workflow

workflow "Slack - New Issues" {
  resolves = ["Slack Notification for New Issues"]
  on = "issues"
}

action "Slack Notification for New Issues" {
  uses = "Ilshidur/action-slack@6aeb2acb39f91da283faf4c76898a723a03b2264"
  secrets = ["SLACK_WEBHOOK"]
  args = "A new issue has been added. \\nURL - {{ EVENT_PAYLOAD.issue.html_url }} \\nTitle - {{ EVENT_PAYLOAD.issue.title }} \\nBody - {{ EVENT_PAYLOAD.issue.body }}"
}

This just needed the m Regexp parameter, allowing multi line replacement.

Here’s the final fix : Ilshidur/action-slack@9273a03

Hello.

You are right. Forgetting to use a RegExp was a mistake. This testifies that this code needs some unit tests 😄

I released a fix.
