Nice that you didn't even need to depend on Genshi template filters! Two suggestions for anyone taking this further: 1. Search ticket custom fields of type Text with format=wiki 2. Include "issue:" TracLinks in the regex: https://trac.edgewall.org/browser/tags/trac-1.2.3/tracopt/ticket/commit_updater.py?marks=140#L139 For more complex formatting of the ticket list, the user has the option to add the ticket numbers as script data and format the list using JavaScript. - Ryan -- You received this message because you are subscribed to the Google Groups "Trac Users" group.
