Welcome to Trac 0.9.5


Provide a list of known InterTrac? prefixes.


This macro displays a tag cloud (weighted list) of all tags.

tagspace=Specify the tagspace the macro should operate on.
tagspaces=(,...)Specify a set of tagspaces the macro should operate on.
smallest=The lower bound of the font size for the tag cloud.
biggest=The upper bound of the font size for the tag cloud.
showcount=true|falseShow the count of objects for each tag?
mincount=Hide tags with a count less than .

List tagged objects. Optionally accepts a list of tags to match against. The special tag . (dot) inserts the current Wiki page name.

[[ListTagged(, ...)]]

tagspace=Specify the tagspace the macro should operate on.
tagspaces=(,...)Specify a set of tagspaces the macro should operate on.
operation=intersection|unionThe set operation to perform on the discovered objects.
showheadings=true|falseList objects under the tagspace they occur in.
expression=Match object tags against the given expression.

The supported expression operators are: unary - (not); binary +, - and | (and, and not, or). All values in the expression are treated as tags. Any tag not in the same form as a Python variable must be quoted.

eg. Match all objects tagged with ticket and workflow, and not tagged with wiki or closed.


If an expression is provided operation is ignored.


Deprecated. Does nothing.


List all tags.

tagspace=Specify the tagspace the macro should operate on.
tagspaces=(,...)Specify a set of tagspaces the macro should operate on.
shownames=true|falseWhether to show the objects that tags appear on (long).

Inserts an alphabetic list of all wiki pages into the output.

Accepts a prefix string as parameter: if provided, only pages with names that start with the prefix are included in the resulting list. If this parameter is omitted, all pages are listed.


Lists all pages that have recently been modified, grouping them by the day they were last modified.

This macro accepts two parameters. The first is a prefix string: if provided, only pages with names that start with the prefix are included in the resulting list. If this parameter is omitted, all pages are listed.

The second parameter is a number for limiting the number of pages returned. For example, specifying a limit of 5 will result in only the five most recently changed pages to be included in the list.


Displays a structural outline of the current wiki page, each item in the outline being a link to the corresponding heading.

This macro accepts three optional parameters:

  • The first is a number or range that allows configuring the minimum and maximum level of headings that should be included in the outline. For example, specifying "1" here will result in only the top-level headings being included in the outline. Specifying "2-3" will make the outline include all headings of level 2 and 3, as a nested list. The default is to include all heading levels.
  • The second parameter can be used to specify a custom title (the default is no title).
  • The third parameter selects the style of the outline. This can be either inline or pullout (the latter being the default). The inline style renders the outline as normal part of the content, while pullout causes the outline to be rendered in a box that is by default floated to the right side of the other content.

Embed an image in wiki-formatted text.

The first argument is the file specification. The file specification may reference attachments or files in three ways:

  • module:id:file, where module can be either wiki or ticket, to refer to the attachment named file of the specified wiki page or ticket.
  • id:file: same as above, but id is either a ticket shorthand or a Wiki page name.
  • file to refer to a local attachment named 'file'. This only works from within that wiki page or a ticket.

Also, the file specification may refer to repository files, using the source:file syntax (source:file@rev works also).

The remaining arguments are optional and allow configuring the attributes and style of the rendered element:

  • digits and unit are interpreted as the size (ex. 120, 25%) for the image
  • right, left, top or bottom are interpreted as the alignment for the image
  • nolink means without link to image source.
  • key=value style are interpreted as HTML attributes or CSS style

indications for the image. Valid keys are:

  • align, border, width, height, alt, title, longdesc, class, id and usemap
  • border can only be a number


    [[Image(photo.jpg)]]                           # simplest
    [[Image(photo.jpg, 120px)]]                    # with size
    [[Image(photo.jpg, right)]]                    # aligned by keyword
    [[Image(photo.jpg, nolink)]]                   # without link to source
    [[Image(photo.jpg, align=right)]]              # aligned by attribute

You can use image from other page, other ticket or other module.

    [[Image(OtherPage:foo.bmp)]]    # if current module is wiki
    [[Image(base/sub:bar.bmp)]]     # from hierarchical wiki page
    [[Image(#3:baz.bmp)]]           # if in a ticket, point to #3
    [[Image(source:/images/bee.jpg)]] # straight from the repository!
    [[Image(htdocs:foo/bar.png)]]   # image file in project htdocs dir.

Displays a list of all installed Wiki macros, including documentation if available.

Optionally, the name of a specific macro can be provided as an argument. In that case, only the documentation for that macro will be rendered.

Note that this macro will not be able to display the documentation of macros if the PythonOptimize option is enabled for mod_python!


Produce documentation for Trac configuration file.

Typically, this will be used in the TracIni page. Optional arguments are a configuration section filter, and a configuration option name filter: only the configuration options whose section and name start with the filters are output.


Example macro.


Inserts the current time (in seconds) into the wiki page.


This macro shows a quick and dirty way to make a table-of-contents for a set of wiki pages.


Macro that lists tickets that match certain criteria.

This macro accepts two parameters, the second of which is optional.

The first parameter is the query itself, and uses the same syntax as for query: wiki links (but not the variant syntax starting with "?").

The second parameter determines how the list of tickets is presented: the default presentation is to list the ticket ID next to the summary, with each ticket on a separate line. If the second parameter is given, it must be one of:

  • compact -- the tickets are presented as a comma-separated list of ticket IDs.
  • count -- only the count of matching tickets is displayed

Displays a blog based on tags

The list of tags to be shown can be specified as arguments to the macro. If no tags are specified as parameters, then the default 'blog' tag is used.

Because any wiki page can be a blog entry,it is suggested that one uses a unique tag for any page that should appear in the blog, such as the tag: 'blog' (the default).

The following options can be specified:

union - Specify whether the join for the tags listed should be a union or intersection(default).
num_posts - Number of posts to display.
year - Year for which to show posts.
month - Month for which to show posts.
day - Day of the month for which to show posts.
delta - How many days of posts should be shown.
mark_update - Specify whether to show "Updated on" for posts that have been updated.
format - Show as RSS feed ('rss') or HTML (else).
post_size - Number of bytes to show before truncating the post and providing a (...) link. Posts are truncated at the next line break after the byte count is reached.

If specifying dates with year, month, and/or day, the current value is specified if missing. For example, if day is specified but year and month are not, then year will be filled in with the current year and month will be filled with the current month. If only year and month are specified, then that indicates the whole month is desired.

The num_posts options is bounded by the date options if combined. For example, if num_posts=5 and month=4 is specified, it will show up to 5 posts from the month of April. If only 3 posts exist, then only 3 are shown. If a date option is not specified, then it will show the last num_posts posts.



Inserts a link to create a new blog post

Accepts keyword arguments that specify default parameters. The macro will be hidden unless the user has BLOG_POSTER permissions.

tag - Tag that populates the "Tag under" field. This key may be specified as a tuple or list to pass multiple values.
blogtitle - Default blog entry title.
text - Default entry body text.
pagename - Default wiki page name.
readonly - Default readonly page status.
link - Text to display as the link.


[[BlogPost(tag=blog,blogtitle="A Simple Title",text="Body Text")]]
[[BlogPost(tag=(blog,pacopablo),link="A New Blog Post")]]

Displays help for trac-admin commands.


[[TracAdminHelp]]               # all commands
[[TracAdminHelp(wiki)]]         # all wiki commands
[[TracAdminHelp(wiki export)]]  # the "wiki export" command
[[TracAdminHelp(upgrade)]]      # the upgrade command

Trac is a minimalistic approach to web-based management of software projects. Its goal is to simplify effective tracking and handling of software issues, enhancements and overall progress.

All aspects of Trac have been designed with the single goal to help developers write great software while staying out of the way and imposing as little as possible on a team's established process and culture.

As all Wiki pages, this page is editable, this means that you can modify the contents of this page simply by using your web-browser. Simply click on the "Edit this page" link at the bottom of the page. WikiFormatting will give you a detailed description of available Wiki formatting commands.

"trac-admin yourenvdir initenv" created a new Trac environment, containing a default set of wiki pages and some sample data. This newly created environment also contains documentation to help you get started with your project.

You can use trac-admin to configure Trac to better fit your project, especially in regard to components, versions and milestones.

TracGuide is a good place to start.
