Hello! First of all, thanks a lot for this Github action, my team has been using it for quite some time and it helps us a lot in our routine.

One question: is there any config option that enables us to only notify a given Slack channel in case of a failure?

Thanks!

Ref: #61 (comment)

You can use the condition: if: failure()

    - name: Slack Notification
      if: failure()
      uses: rtcamp/action-slack-notify@v2
      env:
        SLACK_WEBHOOK: ${{ secrets.SLACK_WEBHOOK }}
        ...

Is it possible to place the answer to this question to README file?
Notification on failure is the most popular use case and the only way to find how to do that is to search for this issue.

@mrrobot47 going back to this topic after a few months :D how can i tag the commit author, so that people can react faster in case they break the build? i'm not sure about how to use the SLACK_LINK_NAMES variable. would it be something like this?

      - name: Notify failures
        if: failure()
        uses: rtCamp/action-slack-notify@v2
        env:
          SLACK_LINK_NAMES: true
          SLACK_CHANNEL: releases
          SLACK_MESSAGE: "hey @$SLACK_MSG_AUTHOR, sorry to let you know you broke the build"

@felipecao Did you ever figure out how to mention the author in the Slack message?

felipecao commented

@sc0ttman not really :(

@sc0ttman i've finally managed to mention author on messages, i've done using a mix of Github actions environment variables and jq

First, i've set an environment variable (Github action secret) that contains a json where i map Github handles with Slack handles:

‘[{“gh_handle": "felipecao", "slack_id": "U01TC0KNKQQ"},{"gh_handle": "otheruser", "slack_id": "otherid"}]’

(make sure to keep the ' character both in the beginning and in the end, it matters)

Then I have a step on my Github workflow YAML file where I use jq to lookup the Slack ID associated with a Github handle:

      - name: Lookup Slack ID
        uses: sergeysova/jq-action@v2
        id: slack_id
        with:
          cmd: jq --raw-output '.[]| select(.gh_handle=="${{ github.actor }}") |.slack_id' <<< ${{ secrets.GH_SLACK_USERS }}

And then I finally reuse that step whenever i want to notify someone:

      - name: Notify
        uses: rtCamp/action-slack-notify@v2
        env:
          SLACK_CHANNEL: my-channel
          SLACK_MESSAGE: "<@${{steps.slack_id.outputs.value}}> check out this message"
          SLACK_WEBHOOK: ${{ secrets.SLACK_WEBHOOK }}
          SLACK_COLOR: ${{ job.status }}

Hope this helps you ;)
