"<p>$settings->sitename's editor uses an extended version of <a href='http://parsedown.org/'>Parsedown</a> to render pages, which is a fantastic open source Github flavoured markdown parser. You can find a quick reference guide on Github flavoured markdown <a href='https://github.com/adam-p/markdown-here/wiki/Markdown-Cheatsheet'>here</a> by <a href='https://github.com/adam-p/'>adam-p</a>, or if you prefer a book <a href='https://www.gitbook.com/book/roachhd/master-markdown/details'>Mastering Markdown</a> by KB is a good read, and free too!</p>
|
|
<h3>Tips</h3>
|
|
<ul>
|
|
<li>Put 2 spaces at the end of a line to add a soft line break. Leave a blank line to add a head line break (i.e. a new paragraph).</li>
|
|
<li>You can add an id to a header that you can link to. Put it in curly braces after the heading name like this: <code># Heading Name {#HeadingId}</code>. Then you can link to like like this: <code>[[Page name#HeadingId}]]</code>. You can also link to a heading id on the current page by omitting the page name: <code>[[#HeadingId]]</code>.</li>
|
|
</ul>
|
|
<h3>Extra Syntax</h3>
|
|
<p>$settings->sitename's editor also supports some extra custom syntax, some of which is inspired by <a href='https://mediawiki.org/'>Mediawiki</a>.
|
|
<table>
|
|
<tr><th style='width: 40%'>Type this</th><th style='width: 20%'>To get this</th><th>Comments</th></th>
|
|
<tr><td><code>[[Internal link]]</code></td><td><a href='?page=Internal%20link'>Internal Link</a></td><td>An internal link.</td></tr>
|
|
<tr><td><code>[[Display Text|Internal link]]</code></td><td><a href='?page=Internal%20link'>Display Text</a></td><td>An internal link with some display text.</td></tr>
|
|
<tr><td><code></code></td><td><img src='http://example.com/path/to/image.png' alt='Alt text' style='float: right; max-width: 256px; max-height: 256px;' /></td><td>An image floating to the right of the page that fits inside a 256px x 256px box, preserving aspect ratio.</td></tr>
|
|
<tr><td><code></code></td><td><figure><img src='http://example.com/path/to/image.png' alt='Alt text' style='max-width: 256px; max-height: 256px;' /><figcaption>Alt text</figcaption></figure></td><td>An image with a caption that fits inside a 256px x 256px box, preserving aspect ratio. The caption is taken from the alt text.</td></tr>
|
|
<tr><td><code></code></td><td><img src='index.php?action=preview&page=Files/Cheese.png' alt='Alt text' style='' /></td><td>An example of the short url syntax for images. Simply enter the page name of an image (or video / audio file), and Pepperminty Wiki will sort out the url for you.</td></tr>
|
|
</table>
|
|
<p>Note that the all image image syntax above can be mixed and matched to your liking. The <code>caption</code> option in particular must come last or next to last.</p>
|
|
<h4>Templating</h4>
|
|
<p>$settings->sitename also supports including one page in another page as a <em>template</em>. The syntax is very similar to that of Mediawiki. For example, <code>{{Announcement banner}}</code> will include the contents of the \"Announcement banner\" page, assuming it exists.</p>
|
|
<p>You can also use variables. Again, the syntax here is very similar to that of Mediawiki - they can be referenced in the included page by surrrounding the variable name in triple curly braces (e.g. <code>{{{Announcement text}}}</code>), and set when including a page with the bar syntax (e.g. <code>{{Announcement banner | importance = high | text = Maintenance has been planned for tonight.}}</code>). Currently the only restriction in templates and variables is that you may not include a closing curly brace (<code>}</code>) in the page name, variable name, or value.</p>
|
|
<h5>Special Variables</h5>
|
|
<p>$settings->sitename also supports a number of special built-in variables. Their syntax and function are described below:</p>
|
|
<table>
|
|
<tr><th>Type this</th><th>To get this</th></tr>
|
|
<tr><td><code>{{{@}}}</code></td><td>Lists all variables and their values in a table.</td></tr>
|
|
<tr><td><code>{{{#}}}</code></td><td>Shows a 'stack trace', outlining all the parent includes of the current page being parsed.</td></tr>
|
|
<tr><td><code>{{{~}}}</code></td><td>Outputs the requested pagee's name.</td></tr>
|
|
<tr><td><code>{{{*}}}</code></td><td>Outputs a comma separated list of all the subpages of the current page.</td></tr>
|
|
<tr><td><code>{{{+}}}</code></td><td>Shows a gallery containing all the files that are sub pages of the current page.</td></tr>
|
|
</table>");
|
|
}
|
|
]);
