We are using YouTrack for our project development. There is an automatic feature that allows us to enter a project code and issue number, eg: ab-101, in descriptions and comments and, when the description or comment is added, the text 'ab-101' becomes a hyperlink that links to that project's task number details page.
What I would like to do is also be able to enter text like, ex-1234 or ex:1234 (can be any format that would work) and when the description/comment is saved it is turned into a link that goes to an external URL, eg: ex-1234 becomes a hyperlink to http://somesite/somepage?id=1234
I think it would involve adding a custom link type and then creating a custom workflow that did the parsing and transformations.
I did some Google searching but came up empty. I am hoping someone has done this and can explain how to set this up or share their workflow code to get me started.
