        <h3><a name="3" class="wiki-page"></a>Redmine links</h3>

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

        <ul>

            <li>Link to an issue: <strong>#124</strong> (displays <del><a href="#" class="issue" title="bulk edit doesn't change the category or fixed version properties (Closed)">#124</a></del>, link is striked-through if the issue is closed)</li>

            <li>Link to an issue including tracker name and subject: <strong>##124</strong> (displays <a href="#" class="issue" title="bulk edit doesn't change the category or fixed version properties (New)">Bug #124</a>: bulk edit doesn't change the category or fixed version properties)</li>

            <li>Link to an issue note: <strong>#124-6</strong>, or <strong>#124#note-6</strong></li>

            <li>Link to an issue note within the same issue: <strong>#note-6</strong></li>

        </ul>

        <p>Wiki links:</p>

        <ul>

            <li><strong>[[Guide]]</strong> displays a link to the page named 'Guide': <a href="#" class="wiki-page">Guide</a></li>

            <li><strong>[[Guide#further-reading]]</strong> takes you to the anchor "further-reading". Headings get automatically assigned anchors so that you can refer to them: <a href="#" class="wiki-page">Guide</a></li>

            <li><strong>[[#further-reading]]</strong> link to the anchor "further-reading" of the current page: <a href="#" class="wiki-page">#further-reading</a></li>

            <li><strong>[[Guide|User manual]]</strong> displays a link to the same page but with a different text: <a href="#" class="wiki-page">User manual</a></li>

        </ul>

        <p>You can also link to pages of an other project wiki:</p>

        <ul>

            <li><strong>[[sandbox:some page]]</strong> displays a link to the page named 'Some page' of the Sandbox wiki</li>

            <li><strong>[[sandbox:]]</strong> displays a link to the Sandbox wiki main page</li>

        </ul>

        <p>Wiki links are displayed in red if the page doesn't exist yet, eg: <a href="#" class="wiki-page new">Nonexistent page</a>.</p>

        <p>Links to other resources:</p>

        <ul>

            <li>Documents:

                <ul>

                    <li><strong>document#17</strong> (link to document with id 17)</li>

                    <li><strong>document:Greetings</strong> (link to the document with title "Greetings")</li>

                    <li><strong>document:"Some document"</strong> (double quotes can be used when document title contains spaces)</li>

                    <li><strong>sandbox:document:"Some document"</strong> (link to a document with title "Some document" in other project "sandbox")</li>

                </ul>

        <p>Escaping:</p>

        <ul>

            <li>You can prevent Redmine links from being parsed by preceding them with an exclamation mark: !</li>

        </ul>

        <h3><a name="4" class="wiki-page"></a>External links</h3>

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

<pre>

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

</pre>

        <p>displays: <a class="external" href="http://www.redmine.org">http://www.redmine.org</a>, <a href="mailto:someone@foo.bar" class="email">someone@foo.bar</a></p>

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

<pre>

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

</pre>

        <p>displays: <a href="http://www.redmine.org" class="external">Redmine web site</a></p>

    <h2><a name="5" class="wiki-page"></a>Text formatting</h2>

<p>For things such as headlines, bold, tables, lists, Redmine supports Markdown syntax according to <a class="external" href="https://commonmark.org/">CommonMark</a> including some extensions commonly referred to as <em>GitHub flavored Markdown</em>. See the <a class="external" href="https://github.github.com/gfm">GitHub Flavored Markdown Spec</a> for information on using any of these features.  A few samples are included below, but the engine is capable of much more of that.</p>

        <h3><a name="6" class="wiki-page"></a>Font style</h3>

<pre>

* **bold**

* *Italic*

* ***bold italic***

* ~~strike-through~~

</pre>

        <p>Display:</p>

        <ul>

            <li><strong>bold</strong></li>

            <li><em>italic</em></li>

            <li><em><strong>bold italic</strong></em></li>

            <li><del>strike-through</del></li>

        </ul>

        <h3><a name="7" class="wiki-page"></a>Inline images</h3>

        <ul>

            <li><strong>![](image_url)</strong> displays an image located at image_url (markdown syntax)</li>

            <li>If you have an image attached to your wiki page, it can be displayed inline using its filename: <strong>![](attached_image)</strong></li>

            <li>Images in your computer's clipboard can be pasted directly using Ctrl-v or Command-v.</li>

            <li>Image files can be dragged onto the text area in order to be uploaded and embedded.</li>

        </ul>

        <h3><a name="8" class="wiki-page"></a>Headings</h3>

<pre>

# Heading

## Subheading

### Subsubheading

</pre>

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

        <h3><a name="10" class="wiki-page"></a>Blockquotes</h3>

        <p>Start the paragraph with <strong>&gt;</strong></p>

<pre>

    <h2><a name="12" class="wiki-page"></a>Macros</h2>

    <p>Redmine has the following builtin macros:</p>

    <p>

    <dl>

      <dt><code>hello_world</code></dt>

      <dd><p>Sample macro.</p></dd>

      <dt><code>macro_list</code></dt>

      <dd><p>Displays a list of all available macros, including description if available.</p></dd>

      <dt><code>child_pages</code></dt>

      <dd><p>Displays a list of child pages. With no argument, it displays the child pages of the current wiki page. Examples:</p>

      <pre><code>{{child_pages}} -- can be used from a wiki page only

{{child_pages(depth=2)}} -- display 2 levels nesting only</code></pre></dd>

      <dt><code>include</code></dt>

      <dd><p>Include a wiki page. Example:</p>

      <pre><code>{{include(Foo)}}</code></pre>

It can be expanded by clicking a link.

}}</code></pre></dd>

      <dt><code>thumbnail</code></dt>

      <dd><p>Displays a clickable thumbnail of an attached image. Examples:</p>

      <pre>{{thumbnail(image.png)}}

{{thumbnail(image.png, size=300, title=Thumbnail)}}</pre></dd>

      <dt><code>issue</code></dt>

      <dd><p>Inserts a link to an issue with flexible text. Examples:</p>

      <pre>{{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

    <h2><a name="13" class="wiki-page"></a>Code highlighting</h2>

    <p>Default code highlighting relies on <a href="http://rouge.jneen.net/" class="external">Rouge</a>, a syntax highlighting library written in pure Ruby. It supports many commonly used languages such as <strong>c</strong>, <strong>cpp</strong> (c++), <strong>csharp</strong> (c#, cs), <strong>css</strong>, <strong>diff</strong> (patch, udiff), <strong>go</strong> (golang), <strong>groovy</strong>, <strong>html</strong>, <strong>java</strong>, <strong>javascript</strong> (js), <strong>kotlin</strong>, <strong>objective_c</strong> (objc), <strong>perl</strong> (pl), <strong>php</strong>, <strong>python</strong> (py), <strong>r</strong>, <strong>ruby</strong> (rb), <strong>sass</strong>, <strong>scala</strong>, <strong>shell</strong> (bash, zsh, ksh, sh), <strong>sql</strong>, <strong>swift</strong>, <strong>xml</strong> and <strong>yaml</strong> (yml) languages, where the names inside parentheses are aliases. Please refer to <a href="https://www.redmine.org/projects/redmine/wiki/RedmineCodeHighlightingLanguages" class="external">https://www.redmine.org/projects/redmine/wiki/RedmineCodeHighlightingLanguages</a> for the full list of supported languages.</p>

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

<pre>

```ruby

  Place your code here.

```

</pre>

    <p>Example:</p>

<pre><code class="ruby syntaxhl"><span class="c1"># The Greeter class</span>

<span class="k">class</span> <span class="nc">Greeter</span>

  <span class="k">def</span> <span class="nf">initialize</span><span class="p">(</span><span class="nb">name</span><span class="p">)</span>

    <span class="vi">@name</span> <span class="o">=</span> <span class="nb">name</span><span class="p">.</span><span class="nf">capitalize</span>

  <span class="k">end</span>

  <span class="k">def</span> <span class="nf">salute</span>

    <span class="nb">puts</span> <span class="s2">"Hello </span><span class="si">#{</span><span class="vi">@name</span><span class="si">}</span><span class="s2">!"</span>

  <span class="k">end</span>

<span class="k">end</span>

</code></pre>

    <h2><a name="15" class="wiki-page"></a>Raw HTML</h2>

    <p>You may use raw HTML for more complex formatting tasks, i.e. complex tables with cells spanning multiple rows or columns:</p>

  <pre><code>

    <table width="50%">

      <tr><td rowspan="2">Two rows</td><td>foo</td></tr>

      <tr><td>bar</td></tr>

      <tr><td align="center" colspan="2">bar</td></tr>

    </table>

  </code></pre>

  <p>yields</p>

<table width="50%" class="sample">

<tr><td rowspan="2">Two rows</td><td>foo</td></tr>

<tr><td>bar</td></tr>

<tr><td align="center" colspan="2">bar</td></tr>

</table>

</body>

</html>

table.sample { border-collapse: collapse; border-spacing: 0; margin: 4px; margin-left: 30px;}

table.sample th, table.sample td { border: solid 1px #bbb; padding: 4px; height: 1em; }
