Markdown formatting

Below is Markdown formatting. For Textile formatting see Textile formatting.
Currently HTML tags are not allowed by default. See #15520 and #20497 for details. For other limitations of the current Markdown formatting see #16373 and #21443.

Links

Redmine links

Redmine allows hyperlinking between resources (wiki pages, issues, documents...) from anywhere text formatting is used.

Wiki links:

You can also link to pages of another project's wiki (using the project identifier):

Wiki links are displayed in red if the page doesn't exist yet, eg: Nonexistent page.

Links to other resources:

Escaping:

External links

HTTP URLs are automatically turned into clickable links:

HTTP URLs can also use different text than the link itself:

Redmine web site

Email addresses

Email addresses are automatically turned into clickable links:

More complex email instructions can be added to an email link. A default subject, default body and CC information can be defined. Note that spaces in any of these fields need to be replaced with the code %20.

Text formatting

For things such as headlines, bold, tables, lists, Redmine supports Markdown syntax. See http://daringfireball.net/projects/markdown/syntax, http://agea.github.io/tutorial.md/, http://stackoverflow.com/editing-help for information on using any of these features. A few samples are included below, but the engine is capable of much more of that. For conversions see Pandoc. The Redcarpet formatter is used.

Note: HTML tags need to be allowed to use the HTML tags (<ins>, <del>, <sup>, <sub>). See #15520-16 and #15520-17 for details.

Color

* <span style="color:red">red</span> <span style="color:green">green</span> <span style="color:yellow">yellow</span> <span style="color:#82B6E1">blue'ish</span>
* <span style="color:red">red</span><span style="color:green">green</span><span style="color:yellow">yellow</span><span style="color:#82B6E1">blue'ish</span>

displays:

Note: HTML tags need to be allowed to use the HTML tag (<span>). See #15520-16 and #15520-17 for details.

Inline images

If you have an image attached to your wiki page, it can be displayed inline using its filename: ![](attached_image.png).

As of this writing, Markdown has no syntax for specifying the dimensions of an image; if this is important to you, you can use regular HTML <img> tags.

Note: HTML tags need to be allowed to use the HTML tag (<img>). See #15520-16 and #15520-17 for details.

Headings

# Heading

## Subheading

### Subheading

or

Heading
=======

Subheading
----------

Redmine assigns an anchor to each of those headings thus you can link to them with "#Heading", "#Subheading" and so forth.

Paragraphs

Markdown does not support alignment of a paragraph. Use <div> tags if you need it.

left aligned
<div style="padding-left:1em;">
left ident 1em
</div>

<div style="padding-left:2em;">
left ident 2em
as well as for following lines
</div>

<div style="text-align:right;">
right aligned
</div>

<div style="padding-right:3em;text-align:right;">
right ident 3em
</div>

<div style="text-align:center;">
This is centered paragraph.
</div>

displays;

left aligned

left ident 1em

left ident 2em
as well as for following lines

right aligned

right ident 3em

This is centered paragraph.

Note: HTML tags need to be allowed to use the HTML tags (<div>). See #15520-16 and #15520-17 for details.

Horizontal rule

----

displays:

Preformatted Text

 <pre>**Your text won't become bold**</pre>

displays:

**Your text won't become bold**

Blockquotes

You can use > at the beginning of each line and stack them for nested quotes:

>> Rails is a full-stack framework for developing database-backed web applications according to the Model-View-Control pattern.
>> To go live, all you need to add is a database and a web server.
> Great!

displays:

Rails is a full-stack framework for developing database-backed web applications according to the Model-View-Control pattern.
To go live, all you need to add is a database and a web server.

Great!

Unordered lists

Unordered lists use asterisks (*), pluses (+), and hyphens (-) as list markers

* Item 1
* Item 2
  * Item 21 (two spaces indentation)
  * Item 22
* Item 3

displays:

Ordered lists

Ordered lists use numbers followed by periods.

1. Item 1
3. Item 2
2. Item 3
  1. Item 3.1 (two spaces)
  1. Item 3.2

displays:

  1. Item 1
  2. Item 2
  3. Item 3
    1. Item 3.1
    2. Item 3.2

Note that the actual numbers you use to mark the list have no effect on the output.

Tables

Markdown does not have syntax for a table. Use an HTML table to write a table.

<table>
  <tr><td style="text-align:center;"><strong>UserID</strong></td><td style="text-align:center;"><strong>Name</strong></td><td style="text-align:center;"><strong>Group</strong></td><td style="text-align:center;"><strong>attribute list</strong></td></tr>
  <tr><td>Starting with</td><td>a</td><td>simple</td><td>row</td></tr>
  <tr><td style="text-align:center;" colspan="3">IT</td><td>align left</td></tr>
  <tr><td>1</td><td>Artur Pirozhkov</td><td rowspan="2">Users</td><td style="text-align:right;">align right</td></tr>
  <tr><td>2</td><td>Vasya Rogov</td><td style="text-align:center;">center</td></tr>
  <tr><td rowspan="2">3</td><td rowspan="2">John Smith</td><td>Admin</td><td style="vertical-align:top;" rowspan="2">valign top</td></tr>
  <tr><td>(root)</td></tr>
  <tr><td rowspan="2">4</td><td rowspan="2">-</td><td>Nobody</td><td style="vertical-align:bottom;" rowspan="2">valign bottom</td></tr>
  <tr><td>(anonymous)</td></tr>
</table>

displays;

UserID Name Group attribute list
Starting with a simple row
IT align left
1 Artur Pirozhkov Users align right
2 Vasya Rogov center
3 John Smith Admin
(root) 		valign top
4 - Nobody
(anonymous) 		valign bottom

Note: HTML tags need to be allowed to use the HTML tags (<table>, <tr>, <td>). See #15520-16 and #15520-17 for details.

Table of content

{{toc}} => left aligned toc
{{>toc}} => right aligned toc

Please keep in mind, that the toc-tag needs an empty line above and underneath it and no other text before and after it.

Example:

h1. headLineOne

h2. something

{{toc}}

h2. something more

Macros

Redmine includes a macros system that lets you add custom functions to insert dynamic content in formatted text. You can learn about writing your own macros in RedmineMacros. Redmine also includes a few builtin macros:

hello_world

Sample macro.

macro_list

Displays a list of all available macros, including description if available.

child_pages

Displays a list of child pages. With no argument, it displays the child pages of the current wiki page. Examples:

!{{child_pages}} -- can be used from a wiki page only
!{{child_pages(depth=2)}} -- display 2 levels nesting only
include

Include a wiki page. Example:

!{{include(Foo)}}

or to include a page of a specific project wiki:

!{{include(projectname:Foo)}}
collapse

Inserts of collapsed block of text. Example:

{{collapse(View details...)
This is a block of text that is collapsed by default.
It can be expanded by clicking a link.
}}
thumbnail

Displays a clickable thumbnail of an attached image. Examples:

{{thumbnail(image.png)}}
{{thumbnail(image.png, size=300, title=Thumbnail)}}
sample_macro

Sample macro

Code highlighting

Code highlighting relies on CodeRay, a
fast syntax highlighting library written completely in Ruby. It
currently supports C, C++, CSS, Delphi, Diff, Groovy, HTML, Java,
Javascript, JSON, Nitro-XHTML, PHP, Python, RHTML, Ruby, Scheme, SQL,
XML and YAML code.

You can highlight code in your wiki page using this syntax:

``` ruby
Place your code here.
```

Example:

# The Greeter class
class Greeter
  def initialize(name)
    @name = name.capitalize
  end

  def salute
    puts "Hello #{@name}!" 
  end
end
