Trac Navigation
The main and meta navigation entries can be customized in several ways. The [mainnav] and [metanav] configuration sections can be used to customize the navigation item text and link, change the ordering of the navigation items, disable them and add new ones.
The primary attributes that can be customized are href, label, order and permission.
[mainnav]
[mainnav] corresponds to the main navigation bar, the one containing entries such as Wiki, Timeline, Roadmap, Browse Source and so on. This navigation bar is meant to access the default page of the main modules enabled in Trac that are accessible for the current user.
Example
In the following example we rename the link to WikiStart Home, and make the View Tickets entry link to a specific report.
[mainnav] wiki.label = Home tickets.href = /report/24
Note the entries on the main navigation are displayed in uppercase regardless of the casing of the label, unless this aspect of the styling is overridden through interface customization.
[metanav]
[metanav] corresponds to the meta navigation bar, by default positioned above the main navigation bar and below the Search box. It contains the Login, Logout, Help/Guide etc. entries. This navigation bar is meant to access some global information about the Trac project and the current user.
There is one special entry in the [metanav] section: logout.redirect is the page the user sees after hitting the logout button. The Help/Guide link is also hidden in the following example.
Example
[metanav] help = disabled logout.redirect = wiki/Logout
Extra Navigation Entries
New navigation entries can be arbitrarily defined and added
to the navigation. A new entry can be defined by providing a name with value enabled. At a minimum, the href attribute should be specified to define a useful navigation entry. If the label attribute is not defined the entry's name will be used for the label.
The following example creates two new navigation items, one named My Reports and the other named builds. My Reports is only visible to users with REPORT_VIEW permission.
[mainnav] myreports = enabled myreports.href = /report/9 myreports.label = My Reports myreports.permission = REPORT_VIEW [metanav] builds = enabled builds.href = https://travis-ci.org/edgewall/trac
The entry names are always read as lowercase, as is the case for all keys in the trac.ini file due to the way the configuration parser is configured. If the example above used BUILDS rather than builds for the name, the entry would still be displayed as builds. Use the label attribute for case-sensitive customization of the navigation entry text.
Relocating Entries
Navigation entries provided by Trac and plugins can be moved from the meta navigation bar to the main navigation bar, and vise-versa. The entry should be defined in the desired category as if it was a new entry. For example, to move the Admin entry to the metanav and rename it to Administration:
[metanav] admin = enabled admin.label = Administration
Attributes of the navigation item that are not overridden by the configuration will be preserved.
URL Formats
Possible URL formats for .href or .redirect:
| config | redirect to |
wiki/Logout | /projects/env/wiki/Logout
|
http://hostname/ | http://hostname/
|
/projects | /projects
|
Ordering
The order attribute specifies the order in which the navigation items are displayed. This can be particularly useful for plugins that add navigation items.
Non-negative floating point values may be used for the order attribute. The navigation items will be arranged from left to right in increasing order. Navigation items without an order attribute are sorted alphabetically by name.
The default values are:
[mainnav] browser.order = 4 newticket.order = 6 roadmap.order = 3 search.order = 7 tickets.order = 5 timeline.order = 2 wiki.order = 1 [metanav] about.order = 5 help.order = 4 login.order = 1 logout.order = 2 prefs.order = 3
Permissions
The permission attribute controls the visibility of the navigation item on the navigation bar. This is mainly useful for new entries in the navigation bar. Note that it does not provide access control to the URL that the navigation item directs to, and cannot override permission checks done by Trac and plugins.
For example, the Roadmap navigation item will only display for users with ROADMAP_VIEW. Adding the attribute roadmap.permission = MILESTONE_VIEW will require both ROADMAP_VIEW and MILESTONE_VIEW for the entry to be visible, but as noted will not provide access control for the /roadmap path. TracFineGrainedPermissions should be used for access control to modules provided by Trac and plugins.
Context Navigation
Note that it is still not possible to customize the contextual navigation bar, i.e. the one usually placed below the main navigation bar.
