There is feature for Referencing issues in commit messages.

Let's say I'd like to add some "properties":http://tortoisesvn.net/docs/nightly/TortoiseSVN_en/tsvn-dug-bugtracker.html during repository creation to highlight the issue's URL or keywords from above feature in TortoiseSVN commit dialogue window in log message.

To achieve result as on picture above I need to set such changes in my working copy and commit changes:

• svn propset bugtraq:url "http://redmine.com/issues/%BUGID%" .
• svn propset bugtraq:logregex "([Rr]efs #\d+)|([Ff]ixes #\d+) (\d+)" There should be extra option in reposman.rb to accept new optional argument, say --propset. This argument have to point to text file with properties defined. Then we execute:

  ruby reposman.rb --redmine my.redmine.host \
  --svn-dir /var/svn --owner www-data \
  --url http://my.svn.server/svn/ \
  --key=my_api_key \
  --propset /root/repositorysettings.txt
  

  and /root/repositorysettings.txt contains:

  bugtraq:url "http://redmine.com/issues/%BUGID%" .
  bugtraq:logregex "([Rr]efs #\d+)|([Ff]ixes #\d+) (\d+)"
