I am receiving messages on Slack from Jenkins via the Slack Plugin. I noticed that the message body is collapsed when it gets to a certain length as shown in the screenshot.

Jenkins - Slack message[2]

I would like to expand these messages by default because I cannot see what happened on Jenkins. I have to manually click on "Show more..." for every message.

I am using the Slack App for Mac v.2.6.3. I could not find a setting in the preferences.

  • You can probably only do this via a userscript (at least via the web interface - you may be able to do something similar for the app). I don't use Slack so I can't really help you, but essentially you can use something like GreaseMonkey and have a script check for posts from Jenkins, auto-clicking the "show more" button then – Zach Saucier Jun 20 '17 at 15:23
  • I am aware of GreaseMonkey as an browser addon and I use it for other websites. In this case however I use the Slack MacOS app. I am not aware that I can use GreaseMonkey for a standalone app. – JJD Jun 22 '17 at 9:17
