Regex is duplicating parts of a URL

[Patrick Haley]

Hey everyone, 

I'm trying to create an automation that when a link to an external Jira issue is added to the comments, it pastes the link into a custom External URL field. I'm new to regex so to test it I'm just having Jira bot return a comment with the URL.

When I add the URL into a comment as a hyperlink, Jira bot returns the URL back twice. However, If I paste a non-hyperlinked URL into the comments, it works correctly.

I'm not exactly sure what I'm missing when I try to insert {{issue.comment.last.body.match("(https:\/\/jira.test.com\/browse\/ABC-\d+)")}} into the comment. 

Any help is greatly appreciated.

Hi @Patrick Haley 

If you were to export that issue with the comment and look at the body, I expect you will see it includes something like this

[https://jira.test.com/browse/ABC-135|https://jira.test.com/browse/ABC-135|smart-link]

So the URL is in there twice and so needs to be parsed accordingly, such as using the Match to make it a list, and then returning only one entry.

Best regards,
Bill

How do you make a list from the match and then return just that value?

I can think of two ways to accomplish your goal:

• no list: Modify the regex to account for that pipe symbol (so you only get one URL), and then strip off the extraneous characters with the replaceAll function
• with list, and easier: Please note in your comment how Match added a comma between the values, so it should already be a list.  You can just grab one by adding .first after your Match call.
