  1. Enable TracChangeFileBiffPlugin in the Plugins page of the web administration menu.
  2. Access to File Biff admin panel: The option of ticket-custom section would be added when you access to File Biff admin page like this:
filebiff = text
filebiff.format = list
filebiff.label = Biff       ; change file label as you like
filebiff.multiple = true    ; this option is used by TracMultiSelectBoxPlugin
filebiff.options =          ; will be set when you configure File Biff settings
filebiff.size = 3           ; this option is used by TracMultiSelectBoxPlugin
filebiff.matching_pattern = fnmatch ; glob matching pattern (fnmatch or gitignore)
  1. Configure File Biff settings:


  • White-space is not allowed in the Name.
  • Cc and Filename are configured as multiple values separated by comma.
  • The glob pattern for Filename is allowed.
  • The glob pattern is configurable in filebiff.matching_pattern of [ticket-custom]. The possible values are:

Add a [changefilebiff] section after you configured File Biff settings like this:

[changefilebiff] = user1
biff.2e320ca20d1aed6a.filename = *.txt, *.text = text-files = user2, guest1
biff.319ddde3cb437ffc.filename = *.properties = property-files = user1, user2
biff.dd487b83e5e76d08.filename = *.gif, *.png, *.jpg = Image-files
biff_keys = dd487b83e5e76d08, 319ddde3cb437ffc, 2e320ca20d1aed6a


Set Biff value automatically when a user committed into the repository:
