<div class="markdown_syntax_section hidden_in_modal md_ex_links{{id}}">
<h2 id="md_ex_links{{id}}">Links</h2>

<p>Most URLs will automatically be turned into links.  To be explicit, just write it like this:</p>

<div class="codehilite"><pre>
&lt;http://someurl&gt;

&lt;somebbob@example.com&gt;

</pre></div>

<p>Output:</p>
{{g.markdown.convert('''
<http://someurl>

<somebbob@example.com>''')}}

<p>To use text for the link, write it:</p>
<div class="codehilite"><pre>[like this](http://someurl)</pre></div>

<p>Output:</p>
{{g.markdown.convert('''[like this](http://someurl)''')}}

<p>You can add a *title* (which shows up under the cursor):</p>
<div class="codehilite"><pre>[like this](http://someurl "this title shows up when you hover")</pre></div>

<p>Output:</p>
{{g.markdown.convert('''[like this](http://someurl "this title shows up when you hover")''')}}
</div>


<div class="markdown_syntax_section hidden_in_modal md_ex_reflinks{{id}}">
<h2 id="md_ex_reflinks{{id}}">Reference Links</h2>
<div class="codehilite"><pre>You can also put the [link URL][1] below the current paragraph
like [this][2].

   [1]: http://url
   [2]: http://another.url "A funky title"
</pre></div>

{{g.markdown.convert('''You can also put the [link URL][1] below the current paragraph
like [this][2].

[1]: http://url
[2]: http://another.url "A funky title"''')}}

<p>Here the text "link URL" gets linked to "http://url", and the lines
showing "[1]: http://url" won't show anything.</p>

<p>Or you can use a [shortcut][] reference, which links the text
"shortcut" to the link named "[shortcut]" on the next paragraph.</p>

<div class="codehilite"><pre>Or you can use a [shortcut][] reference, which links the text
"shortcut" to the link named "[shortcut]" on the next paragraph.

</div>


<div class="markdown_syntax_section hidden_in_modal md_ex_artlinks{{id}}">
<h2 id="md_ex_artlinks{{id}}">Artifact Links</h2>
<p>Any existing forge resource can be linked with surrounding square brackets ie [MyPage] or [#123].</p>

<p>Links to resources in other tools can be explicitly referenced by adding a tool identifier prefix to the link.
So for instance `[developerwiki:MyPage]` can refer to a wiki page in a `developerwiki` instance.
You can also link to tickets with `[tickets:#123]` assuming there's a 123 ticket in a Tracker instance mounted at `tickets`.
The same is true for forums, or any of the other tools you have installed.
You can even link to tickets in a subproject with `[subproject.tickets:#123]`.</p>

<div class="codehilite"><pre>
[MyPage]
[developerwiki:MyPage]
[#123]
[tickets:#123]
</pre></div>

<p>No example output is available for this one because it only works on real artifacts. Try it in your project!</p>
</div>

<div class="markdown_syntax_section hidden_in_modal md_ex_text{{id}}">
<h2 id="md_ex_text{{id}}">Text</h2>
<p>Use * or _ to emphasize things:</p>
<div class="codehilite"><pre>*this is in italic*  and _so is this_

**this is in bold**  and __so is this__

***this is bold and italic***  and ___so is this___

<h2 id="md_ex_pre{{id}}">Preformatted Text</h2>

<div class="markdown_syntax_section hidden_in_modal md_ex_tables{{id}}">
<h2 id="md_ex_tables{{id}}">Tables</h2>
<p>You can create tables using pipes and dashes like this:</p>
<div class="codehilite"><pre>
  First Header  | Second Header
  ------------- | -------------
  Content Cell  | Content Cell
  Content Cell  | Content Cell
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''

<p>You can use markdown syntax within table cells for formatting:</p>

<div class="codehilite"><pre>
  First Header   | Second Header
  -------------  | -------------
  *Content Cell* | Content Cell
  Content Cell   | Content Cell
</pre></div>

<p>Output:</p>

<p>You can also create tables using HTML code.</p>
</div>

<div class="markdown_syntax_section hidden_in_modal md_ex_headers{{id}}">
<h2 id="md_ex_headers{{id}}">Headers</h2>
<p>Just put 1 or more dashes or equals signs (--- or ===) below the
title.</p>
<div class="codehilite"><pre>This is a huge header

------------------
</pre></div>

<p>Output:</p>

<div class="markdown_syntax_section hidden_in_modal md_ex_hr{{id}}">
<h2 id="md_ex_hr{{id}}">Horizontal Rule</h2>
<p>Just put three or more *'s or -'s on a line:</p>
<div class="codehilite"><pre>
----------------

<p>Output:</p>
{{g.markdown.convert('''----------------''')}}

<p>Or, you can use single spaces between then, like this:</p>

<div class="codehilite"><pre>
* * *

<p>Output:</p>
{{g.markdown.convert('''* * *''')}}

<p>or</p>

<div class="codehilite"><pre>
- - - - - - -
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''- - - - - - -''')}}

Make sure you have a blank line above the dashes, though, or else:

<div class="codehilite"><pre>

---
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''you will get a header

</div>


<div class="markdown_syntax_section hidden_in_modal md_ex_img{{id}}">
<h2 id="md_ex_img{{id}}">Images</h2>
<p>To include an image, just put a "!" in front of a text link:</p>
<div class="codehilite"><pre>
![alternate text](https://sourceforge.net/images/icon_linux.gif)
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''![alternate text](http://sourceforge.net/images/icon_linux.gif)''')}}

<p>The "alternate text" will show up if the browser can't load the
image.</p>
<p>You can also use a title if you want, like this:</p>
<div class="codehilite"><pre>
![tiny arrow](https://sourceforge.net/images/icon_linux.gif "tiny arrow")
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''![tiny arrow](http://sourceforge.net/images/icon_linux.gif "tiny arrow")''')}}

<p>To reference an attached image, just use the img macro.  You can add more attributes:</p>
<div class="codehilite"><pre>
[[img src=attached-image.jpg alt=foobar]]
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''[[img src=attached-image.jpg alt=foobar]]''')}}
</div>


<div class="markdown_syntax_section hidden_in_modal md_ex_escapes{{id}}">
<h2 id="md_ex_escapes{{id}}">Escapes</h2>
<p>What if you want to just show asterisks, not italics?</p>
<div class="codehilite"><pre>* this shows up in italics: *a happy day*

</pre></div>

<p>Output:</p>
{{g.markdown.convert('''* this shows up in italics: *a happy day*
* this shows the asterisks: \*a happy day\*''')}}

<p>The backslashes will disappear and leave the asterisks.</p>
<p>You can do the same with any of the characters that have a special meaning<br>for Markdown.</p>
<p>HTML tags may need to be escaped.  &lt;b&gt; will be interpreted as a bold tag.  Entity codes will be used.
&lt;foobar&gt; isn't allowed and will be dropped, so you probably want to escape it:</p>
<div class="codehilite"><pre>
&lt;b&gt;this will be bold&lt;/b&gt;
you should escape &amp;lt;unknown&amp;gt; tags
&amp;lt; special entities work
&amp;amp;lt; if you want to escape it
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''<b>this will be bold</b>
you should escape &lt;unknown&gt; tags
&lt; special entities work
&amp;lt; if you want to escape it''')}}
<p>Individual ampersands (&amp;) and less-than signs (&lt;) are fine, they will be shown as expected.</p>
</div>


<div class="markdown_syntax_section hidden_in_modal md_ex_moreheaders{{id}}">
<h2 id="md_ex_moreheaders{{id}}">More Headers</h2>
<p>More ways of doing headers:</p>
<div class="codehilite"><pre># this is a huge header #
## this is a smaller header ##
### this is even smaller ###
#### more small ####
##### even smaller #####
###### smallest still: `&lt;h6&gt;` header

<p>Output:</p>
{{g.markdown.convert('''# this is a huge header #
## this is a smaller header ##
### this is even smaller ###
#### more small ####
##### even smaller #####
###### smallest still: `<h6>` header''')}}
<p>You can use up to 6 <code>#</code> characters at the beginning of the line.</p>
</div>


<div class="markdown_syntax_section hidden_in_modal md_ex_code{{id}}">
<h2 id="md_ex_code{{id}}">Code Highlighting</h2>
<p>The Code highlighting used in the newforge is based on (http://www.freewisdom.org/projects/python-markdown/CodeHilite). It  follows the same syntax as regular Markdown code blocks, except that there are two ways to tell the highlighter what language to use for the code block.</p>

<p>If the first line of the codeblock contains a shebang, the language is derived from that and line numbers are used.</p>

<div class="codehilite"><pre>
    #!/usr/bin/python
    # Code goes here ...
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''
    #!/usr/bin/python
    # Code goes here ...''')}}

<p>If the first line contains a shebang, but the shebang line does not contain a path (a single / or even a space) or If the first line begins with three or more colons, the text following the colons identifies the language. In both cases, the first line is removed from the code block before processing.</p>

<div class="codehilite"><pre>
    :::python
    # Code goes here ...
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''
    :::python
    # Code goes here ...''')}}

<p>You can also designate a code block by surrounding it with lines of tildes. The type of code highlighting to apply will be inferred based on the code within, or you can specify like above.</p>

<div class="codehilite"><pre>
~~~~~~
&lt;a href="#">My code&lt;/a>
~~~~~~
</pre></div>

<p>Output:</p>
{{g.markdown.convert('''

~~~~~~''')}}
