WikiFormatting

Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into flexible and powerful whole.

Trac has a built in small and powerful wiki rendering engine. This wiki engine implements an ever growing subset of the commands from other popular Wikis especially ​MoinWiki.

This page demonstrates the formatting syntax available anywhere WikiFormatting is allowed.

Trac Hacks: Ticket Box

Simple list of tickets by specifiying ticket numbers. '#' character can be omitted: TicketBox(#1,#7,#31)?

[[TicketBox(#1,#7,#31)]]
[[TicketBox(1,7,31)]]

List tickets expanded from the report result. Third example uses dynamic variable. The special variable 'USER' can be specified. If not specified, login name (or anonymous) is used:

[[TicketBox({1})]]
[[TicketBox([report:1])]]
[[TicketBox([report:9?COMPONENT=TicketBox])]]
[[TicketBox([report:9?USER=foo])]]

Combination of above is allowed. The tickets are listed as sorted and uniq'ed:

[[TicketBox({1),#50,{2},100)]]

Specifying a size of the box:

[[TicketBox(500pt,{1})]]
[[TicketBox(200px,{1})]]
[[TicketBox(25%,{1})]]

Specifying a title of the box. single and double quoted string are allowed. If '%d' in title string will be replaced with count of tickets:

[[TicketBox('Related Tickets',#1,#2)]]
[[TicketBox("Related Tickets",#1,#2)]]
[[TicketBox("There are %d tickets",{1})]]

Trac Hack: Table of Content

The TocMacro generates a table of contents for the current page or a set of pages.

If no arguments are given, a table of contents is generated for the current page, with the top-level title stripped:

[[TOC]]

To generate a table of contents for a set of pages, simply pass them as comma separated arguments to the TOC macro. This is the macro call for the table of contents visible on the right side of this page:

[[TOC(TracGuide, TracInstall, TracUpgrade, TracIni, TracAdmin, TracBackup, TracLogging,
TracPermissions, TracWiki, WikiFormatting, TracBrowser, TracRoadmap, TracChangeset,
TracTickets, TracReports, TracQuery, TracTimeline, TracRss, TracNotification)]]

The following control arguments change the default behaviour of the TOC macro:

Argument	Meaning
heading=<x>	Override the default heading of "Table of Contents"
noheading	Suppress display of the heading.
depth=<n>	Display headings of subsequent pages to a maximum depth of <n>.
inline	Display TOC inline rather than as a side-bar.
titleindex	Only display the page name and title of each page, similar to TitleIndex.

Heading

You can create heading by starting a line with one up to five equal

Note: As of writing, headings cannot contain TracLinks.

Example:

= Heading =

Text paragraphs can be indented by starting the lines with two or more spaces.

 * [http://www.edgewall.com/ Edgewall Software]
 * [wiki:TitleIndex Title Index]

Display:

• ​Edgewall Software
• Title Index

Trac Links

• Tickets: #1 or ticket:1
• Reports: {1} or report:1
• Changesets: [1] or changeset:1
• Wiki pages: CamelCase or wiki:CamelCase
• Milestones: milestone:1.0
• Files: source:trunk/COPYING
• A specific file revision: source:/trunk/COPYING#200

Display:

• Tickets: #1 or ticket:1
• Reports: {1} or report:1
• Changesets: [1] or changeset:1
• Wiki pages: CamelCase or wiki:CamelCase
• Milestones: milestone:1.0
• Files: source:trunk/COPYING
• A specific file revision: source:/trunk/COPYING#200

See TracLinks for more in-depth information.

Escaping Links and WikiNames

You may avoid making hyperlinks out of TracLinks by preceding an expression with a single '!' (exclamation mark).

 !NoHyperLink
 !#42 is not a link

Display:

NoHyperLink #42 is not a link

Images

Urls ending with .png, .gif or .jpg are automatically interpreted as image links, and converted to IMG tags.

Example:

http://www.edgewall.com/gfx/trac_example_image.png

​http://www.edgewall.com/gfx/trac_example_image.png

Macros

Macros are custom functions to insert dynamic content in a page. See WikiMacros for usage.

Example:

 [[Timestamp]]

See WikiProcessors for more information.

Example 1:

{{{
#!html
<h1 style="text-align: right; color: blue">HTML Test</h1>
}}}

Display:

HTML Test

Example 2:

{{{
#!python
class Test:
    def __init__(self):
        print "Hello World"
if __name__ == '__main__':
   Test()
}}}
