RedmineWikiFormatting (Markdown)

# Wiki formatting (Markdown)

## Links

### Redmine links

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

- Link to an issue: #124 (displays #124, link is striked-through if the issue is closed)
- Link to an issue including tracker name and subject: ##124 (displays Bug #124: bulk edit doesn't change the category or fixed version properties)
- Link to an issue note: #124-6, or #124#note-6
- Link to an issue note within the same issue: #note-6

Wiki links:

- [[Guide]] displays a link to the page named 'Guide': Guide
- [[Guide#further-reading]] takes you to the anchor "further-reading". Headings get automatically assigned anchors so that you can refer to them: Guide
- [[#further-reading]] link to the anchor "further-reading" of the current page: #further-reading
- [[Guide|User manual]] displays a link to the same page but with a different text: User manual

You can also link to pages of an other project wiki:

- [[sandbox:some page]] displays a link to the page named 'Some page' of the Sandbox wiki
- [[sandbox:]] displays a link to the Sandbox wiki main page

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

Links to other resources:

- Documents:
  - document#17 (link to document with id 17)
  - document:Greetings (link to the document with title "Greetings")

Escaping:

- You can prevent Redmine links from being parsed by preceding them with an exclamation mark: !

### External links

URLs (starting with: www, http, https, ftp, ftps, sftp and sftps) and email addresses are automatically turned into clickable links:

    http://www.redmine.org, someone@foo.bar

displays: http://www.redmine.org, someone@foo.bar

If you want to display a specific text instead of the URL, you can use the standard markdown syntax:

    [Redmine web site](http://www.redmine.org)

displays: Redmine web site

## Text formatting

For things such as headlines, bold, tables, lists, Redmine supports Markdown syntax. See http://daringfireball.net/projects/markdown/syntax for information on using any of these features. A few samples are included below, but the engine is capable of much more of that.

### Font style

    * **bold**
    * *Italic*
    * ***bold italic***
    * _underline_
    * ~~strike-through~~

Display:

- bold
- italic
- bold italic
- underline
- strike-through

### Inline images

- ![](image_url) displays an image located at image_url (markdown syntax)
- If you have an image attached to your wiki page, it can be displayed inline using its filename: ![](attached_image)
- Images in your computer's clipboard can be pasted directly using Ctrl-v or Command-v (note that Internet Explorer is not supported).
- Image files can be dragged onto the text area in order to be uploaded and embedded.

### Headings

    # Heading
    ## Subheading
    ### Subsubheading

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

### Blockquotes

Start the paragraph with >

    > 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.

Display:

> 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.

### Table of content

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

### Horizontal Rule

Redmine has the following 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)}}

`issue`

  Inserts a link to an issue with flexible text. Examples:

      {{issue(123)}}                              -- Issue #123: Enhance macro capabilities
      {{issue(123, project=true)}}                -- Andromeda - Issue #123:Enhance macro capabilities
      {{issue(123, tracker=false)}}               -- #123: Enhance macro capabilities
      {{issue(123, subject=false, project=true)}} -- Andromeda - Issue #123

## Code highlighting

Default code highlighting relies on Rouge, a pure Ruby code highlighter. Rouge supports many commonly used languages such as c, cpp (c++), csharp (c#, cs), css, diff (patch, udiff), go (golang), groovy, html, java, javascript (js), kotlin, objective_c (objc), perl (pl), php, python (py), r, ruby (rb), sass, scala, shell (bash, zsh, ksh, sh), sql, swift, xml and yaml (yml) languages - the names inside parentheses are aliases. Please refer to the list of languages supported by Redmine code highlighter.

You can highlight code at any place that supports wiki formatting using this syntax (note that the language name or alias is case-insensitive):

    ``` 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
