TracIni - Deadman - Linux Kernel Driver - Trac

The Trac Configuration File

Trac configuration is done by editing the trac.ini config file, located in <projectenv>/conf/trac.ini.

Global Configuration

Since version 0.9, Trac can also read the configuration from a global trac.ini file. These global options will then be merged with the environment-specific options, where local options override global options.

The global configuration is by default localted in $prefix/share/trac/conf/trac.ini. It can be moved to a different location (for example, /etc/trac.ini), but that requires changing the file trac/ which gets created when Trac is installed.


This is a brief reference of available configuration options.

(since 0.9)

This section is used to enable or disable components provided by plugins, as well as by Trac itself. The component to enable/disable is specified via the name of the option. Whether its enabled is determined by the option value; setting the value to enabled or on will enable the component, any other value (typically disabled or off) will disable the component.

The option name is either the fully qualified name of the components or the module/package prefix of the component. The former enables/disables a specific component, while the latter enables/disables any component in the specified package/module.

Consider the following configuration snippet:

[components] = disabled
webadmin.* = enabled

The first option tells Trac to disable the report module. The second option instructs Trac to enable all components in the webadmin package. Note that the trailing wildcard is required for module/package matching.

See the Plugins page on About Trac to get the list of active components (requires CONFIG_VIEW permissions.)

Note that prior to Trac r2335 (that applies to 0.9b1 and 0.9b2), you would use a [disabled_components] section instead. See a previous version of this page for the details.
