InterTrac Extension for TracLinks

(since 0.10)


An InterTrac link is used for referring to a Trac object (Wiki page, changeset, ticket, ...) located in another Trac environment.

Link Syntax


The link is composed by the target environment name, followed by a colon (e.g. trac:), followed by a regular TracLinks, of any flavor.

That target environment name is either the real name of the environment, or an alias for it. The aliases are defined in trac.ini (see below). The prefix is case insensitive.

For convenience, there's also an alternative short-hand form, where one can use an alias as an immediate prefix for the identifier of a ticket, changeset or report: (e.g. #T234, [T1508], [trac 1508], ...)


Besides the other environments run by the same server process (called sibling environments), which are automatically detected, (Note: currently only in tracd), it is necessary to setup a configuration for the InterTrac facility:

  • in order to refer to a remote Trac
  • for defining environment aliases

This is done quite simply in an [intertrac] section within the trac.ini file.

Example configuration:

## -- Example of setting up an alias:
t = trac

## -- Link to an external Trac:
trac.title = Edgewall's Trac for Trac
trac.url =

#trac.svn = 
# Hint: .svn information could be used in the future to support svn:externals...

Now, given this configuration, one could create the following links:

Anything not given as explicit links (intertrac_prefix:module:id) is interpreted by the remote Trac, relying on its quickjump facility.
