I meet the same problem. I create a git repo. for observing another remote git repo. Then I add the second user, the commit of the second user can't link correctly. How can I reparse an observing repo. Reparsing via "./bin/repository reparse --importing --all <REPONAME>" didn't do anything.

Could you kindly suggest me extend which Remarkup rule for parsing a specific URL pattern into a token like we do for tasks like T5000.
I can't find where you do this exactly.

Reference: Adding LaTeX support into the Phabricator team collaboration system
Should I extend PhabricatorRemarkupCustomInlineRule also?

Excuse me, I don't really know how to do this.
Should I create a php file like DifferentialJIRAIssuesCommitMessageField.php?
And Differential would treat some pridicular string as a custom field.
Then how do I add parsing external bug tracker id code?
