<h2 id="introduction">1. Introduction</h2>
<p>Here is the official core of <strong>Skriv Markup</strong>'s syntax.</p>
<h3 id="version">1.1 Version</h3>
<p>The <strong>Skriv Markup</strong> syntax' current version is <b class="blue">alpha</b>.</p>
<h3 id="escaping">1.2 Escaping</h3>
<p>
All special characters are escaped. For instance, less-than (<tt>&lt;</tt>), greatear-than (<tt>&gt;</tt>)
and ampersand (<tt>&amp;</tt>) characters are transformed during HTML export (respectively to
<tt>&amp;lt;</tt>, <tt>&amp;gt;</tt> and <tt>&amp;amp;</tt>).
</p>
<p>
Sometimes, it's necessary to prevent some language interpretation, when you want to display something that
should be used as a markup. To do so, you just have to put a backslash (<tt>\</tt>) character in front of the markup.
</p>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
The backslash character is commonly used to escape sequences in text streams, in many programming languages.
More, this character is rarely used in normal texts, so in shouldn't conflict with any other typed characters.
</div>
<h3 id="note-about-spaces">1.3 Note about spaces</h3>
<p>
You'll see that some markups can take several parameters; in this case, the parameters are separated with a
pipe character (<b class="red">|</b>). You can add spaces before and/or after any parameter, they will be removed afterward.
</p>
<p>For example, these four lines produce the exact same link:</p>
<pre><b class="red">[[</b>Skriv<b class="red">|</b>http://skriv.org<b class="red">]]</b>
<b class="red">[[</b> Skriv <b class="red">|</b> http://skriv.org <b class="red">]]</b>
<b class="red">[[</b>Skriv <b class="red">|</b> http://skriv.org<b class="red">]]</b>
<b class="red">[[</b>Skriv <b class="red">|</b>http://skriv.org<b class="red">]]</b></pre>
<p>
In fact, spaces are removed when they are obviously optional. These two lists produce the exact same result:
</p>
<pre><b class="red">*</b>AAA
<b class="red">*</b>BBB
<b class="red">*</b> AAA
<b class="red">*</b> BBB</pre>
<p>
As well as these two titles:
</p>
<pre><b class="red">==</b>Level 2 title<b class="red">==</b>
<b class="red">==</b> Level 2 title <b class="red">==</b></pre>
<p>
And for these tables:
</p>
<pre><b class="red">!!</b>Head 1<b class="red">!!</b>Head 2
<b class="red">||</b>Cell 1<b class="red">||</b>Cell 2
<b class="red">!!</b> Head 1 <b class="red">!!</b> Head 2
<b class="red">||</b> Cell 1 <b class="red">||</b> Cell 2</pre>
<p>
On the other hand, inline markups without parameters don't remove spaces. So these two lines are different:
</p>
<pre><b class="red">**</b>bold text<b class="red">**</b> and <b class="red">''</b>italic text<b class="red">''</b>
<b class="red">**</b> bold text <b class="red">**</b> and <b class="red">''</b> italic text <b class="red">''</b></pre>
<h2 id="paragraphs">2. Paragraphs</h2>
<p>
Out of special blocks, any text is placed inside a paragraph. Paragraphs are separated by one or more blank line.
Inside a paragraph, line-breaks are kept as they are typed.
</p>
<div class="label">Skriv Markup</div>
<pre>Here is the first paragraph.
With two lines.
Here is the second paragraph, with
many
carriage-returns.</pre>
<div class="label">Result</div>
<div class="alert alert-grey">
<p>
Here is the first paragraph.<br />
With two lines.
</p>
<p>
Here is the second paragraph, with<br />
many<br />
carriage-returns.
</p>
</div>
<div class="label">HTML</div>
<pre>&lt;p&gt;
Here is the first paragraph.&lt;br /&gt;
With two lines.
&lt;/p&gt;
&lt;p&gt;
Here is the second paragraph, with&lt;br /&gt;
many&lt;br /&gt;
carriage-returns.
&lt;/p&gt;</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
<p>
Paragraphs are so common that no explicit markup should be necessary to create them.
</p>
<p>
Keep line-breaks seems the best way to ensure a result as close as possible from what
the writer wants. This point of view is shared by <a href="http://github.github.com/github-flavored-markdown/" target="_blank">GitHub Flavored Markdown</a>.
</p>
</div>
<h2 id="basic-styles">3. Basic styles</h2>
<p>
Inline styles are marked up using tags before and after the affected text. These tags are constituted by two identical characters.<br />
These markups can affect full-words only, they are not effective if they are written in the middle of a word.
</p>
<div class="label">Skriv Markup</div>
<pre>works on**ly on full** words</pre>
<div class="label">Output</div>
<div class="alert alert-grey">works on**ly on full** words</div>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
Most of the time, it's totally pointless to apply a style on a chuck of a word. Usually, that could lead to a misunderstanding of the writer's will.
Here again, this point of view is shared by <a href="http://github.github.com/github-flavored-markdown/" target="_blank">GitHub Flavored Markdown</a>.</p>
</div>
<h3 id="italic">3.1 Italic</h3>
<div class="label">Skriv Markup</div>
<pre>two <b class="red">''</b>single quotes<b class="red">''</b> for italic</pre>
<div class="label">Output</div>
<div class="alert alert-grey">two <em>single quotes</em> for italic</div>
<div class="label">HTML</div>
<pre>two &lt;em&gt;single quotes&lt;/em&gt; for italic</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
For light emphasis, the doubled-single-quotes markup is widely used (MediaWiki). The doubled-slash characters (<tt>//</tt>),
used by Creole, is pretty logical; the shape of the slash character reminds the slanted aspect of italic writing.
But the visual impact on the text is overweening compared with the desired result.
</div>
<h3 id="strong">3.2 Strong</h3>
<div class="label">Skriv Markup</div>
<pre>two <b class="red">**</b>asterisks<b class="red">**</b> for bold</pre>
<div class="label">Output</div>
<div class="alert alert-grey">two <strong>asterisks</strong> for bold</div>
<div class="label">HTML</div>
<pre>two &lt;strong&gt;asterisks&lt;/strong&gt; for bold</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
Asterisks are commonly used for strong emphasis (Creole, Markdown, txt2tags, DokuWiki). They are also used in emails since the down of time.
</div>
<h3 id="underline">3.3 Underline</h3>
<div class="label">Skriv Markup</div>
<pre>two <b class="red">__</b>underscores<b class="red">__</b> for underline</pre>
<div class="label">Output</div>
<div class="alert alert-grey">two <u>underscores</u> for underline</div>
<div class="label">HTML</div>
<pre>two &lt;u&gt;underscores&lt;/u&gt; for underline</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
<p>Adding underscores before and after is the perfect markup for underlining, as they are suggesting the beginning and the end of the under line.</p>
<p>This syntax is already used by Creole and DokuWiki.</p>
</div>
<h3 id="strikeout">3.4 Strikeout</h3>
<div class="label">Skriv Markup</div>
<pre>two <b class="red">--</b>minus signs<b class="red">--</b> for striking out</pre>
<div class="label">Output</div>
<div class="alert alert-grey">two <s>minus signs</s> for striking out</div>
<div class="label">HTML</div>
<pre>two &lt;s&gt;minus signs&lt;/s&gt; for striking out</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
The minus signs are good for striked out text, for the same reason than the underscores for underlining.
</div>
<h3 id="monospace">3.5 Monospace</h3>
<div class="label">Skriv Markup</div>
<pre>two <b class="red">##</b>hash signs<b class="red">##</b> for monospace</pre>
<div class="label">Output</div>
<div class="alert alert-grey">two <tt>hash signs</tt> for monospace</div>
<div class="label">HTML</div>
<pre>two &lt;tt&gt;hash signs&lt;/tt&gt; for monospace</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
<p>Hash signs have a very special shape. Their more-or-less squared look is a valid metaphor for monospaced fonts.</p>
<p>This syntax is already used by Creole.</p>
</div>
<h3 id="superscript">3.6 Superscript</h3>
<div class="label">Skriv Markup</div>
<pre>two <b class="red">^^</b>caret characters<b class="red">^^</b> for exponent</pre>
<div class="label">Output</div>
<div class="alert alert-grey">two <sup>caret characters</sup> for exponent</div>
<div class="label">HTML</div>
<pre>two &lt;sup&gt;cart characters&lt;/sup&gt; for exponent</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
<p>Caret characters are like little arrowheads indicating upside direction.</p>
<p>This syntax is already used by Creole.</p>
</div>
<h3 id="subscript">3.7 Subscript</h3>
<div class="label">Skriv Markup</div>
<pre>two <b class="red">,,</b>commas<b class="red">,,</b> for subscript</pre>
<div class="label">Output</div>
<div class="alert alert-grey">two <sub>commas</sub> for subscript</div>
<div class="label">HTML</div>
<pre>two &lt;sub&gt;commas&lt;/sub&gt; for subscript</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
<p>On the contrary, commas are going under the text's baseline, thus they are suggesting to push down the text.</p>
<p>This syntax is already used by Creole.</p>
</div>
<h2 id="titles">4. Titles</h2>
<h3 id="titles-main">4.1 Main syntax</h3>
<p>
Titles are written using one to six equal signs (<tt>=</tt>) at the beginning of the line. One equal sign for a first level heading;
six equal signs for a sixth level heading.
</p>
<p>
For esthetical reasons, it's possible to add as many equal signs at the end of the line than at the beginning. They will be removed.<br />
Spaces are allowed between the markups and the title's text.
</p>
<p>
On HTML output, DOM identifier should be added. It should be possible to prepend a given prefix at the beginning of these identifiers.
</p>
<div class="label">Skriv Markup</div>
<pre><b class="red">=</b>Level 1 heading
<b class="red">==</b> Level 2 heading<b class="red">==</b>
<b class="red">===</b>Level 3 heading <b class="red">===</b>
<b class="red">====</b> Level 4 heading</pre>
<div class="label">HTML</div>
<pre>&lt;h1 id="Level-1-heading"&gt;Level 1 heading&lt;h1&gt;
&lt;h2 id="Level-2-heading"&gt;Level 2 heading&lt;h2&gt;
&lt;h3 id="Level-3-heading"&gt;Level 3 heading&lt;h3&gt;
&lt;h4 id="Level-4-heading"&gt;Level 4 heading&lt;h4&gt;</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
<p>Equals signs are a very widespread mean to write headings among wiki syntaxes (MediaWiki, Creole, txt2tags, DokuWiki).</p>
<p>It's a convenient writing, very fast to type. The visual impact is clear; with more equal signs at the beginning of the line, the title is more
indented, indicating a sub-header.</p>
<p>Equals signs at the end of the line are optional, because some existing wiki syntaxes made it mandatory, some others avoid them.</p>
</div>
<h3 id="titles-identifiers">4.2 User-defined identifiers</h3>
<p>
Because two titles may have the same text, two titles may have the same DOM identifier. It could be a real problem when creating
links pointing to these titles (even for automatically created table of contents).
</p>
<p>
To circumvent this problem, it is possible to override a title identifier by writing it at the end of the line, using the balanced markup.
</p>
<p>
It's always possible to disable this feature, by using the usual escaping character (backslash) before the equal signs, or by using the balanced markup all the time.
</p>
<div class="label">Skriv Markup</div>
<pre><b class="red">===</b>Darth Vador
<b class="red">===</b>Darth Vador<b class="red">===</b>
<b class="red">===</b>Darth Vador<b class="red">===</b><b class="blue">your father</b>
<b class="red">=</b>Darth Vador \= your father

<div class="label">HTML</div>
<pre>&lt;h3 id="Darth-Vador"&gt;Darth Vador&lt;/h3&gt;
&lt;h3 id="Darth-Vador"&gt;Darth Vador&lt;/h3&gt;
&lt;h3 id="your-father"&gt;Darth Vador&lt;/h3&gt;
&lt;h1 id="Darth-Vador-your-father"&gt;Darth Vador = your father&lt;h1&gt;
&lt;h1 id="Darth-Vador-your-father"&gt;Darth Vador = your father&lt;h1&gt;</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
This syntax is the simplest way to define special identifiers, without any fancy addition.
</div>
<h2 id="lists">5. Lists</h2>
<h3 id="unordered-lists">5.1 Unordered lists</h3>
<p>
Unordered lists are also known as “bulleted-lists”. They are written using asterisk characters (<tt>*</tt>), placed at the beginning of the lines.
There must be no space before the asterisks.
</p>
<p>
Sub-lists are created by typing more asterisks.
</p>
<div class="label">Skriv Markup</div>
<pre><b class="red">*</b> Item 1
<b class="red">*</b> Item 2
<b class="red">**</b> Sub-item 2.1

<p>Asterisks character are commonly used to create lists (MediaWiki, Creole, Markdown, reStructuredText, POD, Asciidoc, Textile, WikiWikiWeb, TWiki, MoinMoin, Redmine, ...).</p>
<p>Adding more asterisks at the beginning of the line indent the text as a result. This indentation makes clear where the sublist is.</p>
</div>
<h3 id="ordered-lists">5.2 Ordered lists</h3>
<p>
Items of ordered lists are displayed with an incremented number in front of them. They are written using hash signs (<tt>#</tt>),
placed at the beginning of the lines. There must be no space before the hash signs.
</p>
<p>
Sub-lists are created by typing more hash signs.
</p>
<div class="label">Skriv Markup</div>

&lt;/ul&gt;</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
<p>
The hash sign is a character used to represent numbers, so its usage is understandable for numbered lists.
It's also used by many other languages (MediaWiki, Creole, Textile, Redmine, ...).
</p>
<p>The same mechanisms than for unordered lists are applied, to keep a coherent syntax.</p>
</div>
<h3 id="mixed-lists">5.3 Mixed lists</h3>
<p>
It is possible to mix ordered and unordered lists. The last character used determines the list's type.

&lt;/ul&gt;</pre>
<h2 id="links">6. Links</h2>
<p>
Links are explicitely defined using double-square brackets (<tt>[[&nbsp;]]</tt>). There must be at least the link destination, but it is also
possible to define its title first, separated from the link address with a pipe character (<tt>|</tt>).
</p>
<p>
When no title is given, the address is used as the title, shorten to 40 characters.
</p>
<p>
By default, every outgoing links (those containing "<tt>://</tt>" or starting with "<tt>//</tt>") SHOULD be set with
a <tt>target="_blank"</tt> and a <tt>rel="nofollow"</tt> attributes. This behaviour SHOULD be configurable.

Square brackets are commonly used to represent some kind of reference (MediaWiki, Creole, Markdown, Asciidoc, DokuWiki, TWiki, MoinMoin, ...).
They are doubled to follow the <a href="https://markup.skriv.org/language/intro#rationale">Skriv rationale</a>.
</p>
<p>
When you read some text, the title of a link contains more direct information than its destination address.
That's why the title is written first, before the address, when defined.
</p>
</div>
<h2 id="images">7. Images</h2>
<p>
Images' syntax follows the links' syntax. Double-curly brackets (<tt>{{&nbsp;}}</tt>) are used instead of double-square brackets,
to define the image location. An optional text can be set as the image alternative representation.

Curly brackets are like square brackets, but with a more “artistic” shape. That's enough to distinguish images from regular links.

Double-curly brackets are already used by DokuWiki.

</div>
<h2 id="tables">8. Tables</h2>
<p>
Skriv Markup helps you to create simple tables as quickly as possible. It is not intended to
generate complex tables with merged cells.
</p>
<p>
Each table row starts with a cell delimiter. There is two kinds of cell delimiter: double-pipe (<tt>||</tt>) for normal cells,
and double-exclamation marks (<tt>!!</tt>) for header cells. Every cell begins with a delimiter.
</p>
<div class="label">Skriv Markup</div>

The major goal with the table syntax was to provide a convenient way to create tables, without doing
<a href="http://en.wikipedia.org/wiki/Ascii_art" target="_blank">ascii-art</a>. That's the reason why there is only two
type of cells, no merged cells, and a very simple layout.
</p>
<p>
Pipes are the natural characters to create vertical separations between elements. It's perfect for table representation.
Exclamation marks have a similar shape, with a subtle difference to indicate headers.
</p>
</div>
<h2 id="horizontal-rules">9. Horizontal rules</h2>
<p>
Horizontal rules are done by putting at least four minus signs on the same line, without anything else
on the line. There must be no space before the minus signs.

<h2 id="quotes">10. Quotes</h2>
<p>
To write a quote, add a right angle bracket (<tt>&gt;</tt>) at the beginning of each line.

<h2 id="footnotes">11. Footnotes</h2>
<p>
Footnotes are used to add internal links inside a document, referencing some chunks of text that should
be listed at the bottom of the page.
</p>
<p>
They are defined using double-parenthesis (<tt>(( ))</tt>), where the footnote is referenced. Usually, footnotes
are identified by an incremented number; if you want to use a label in place of that number, write it first,
separated from the footnote's text by a pipe character (<tt>|</tt>).

Preformatted texts are blocks of text rendered using monospace font. Line breaks are kept.

To create a preformatted text block, just add a space character at the beginning of each line
of the block. In fact, once space is enough, but you can put as many spaces as you want.

Adding space characters at the beginning of the line is the fastest way to define a style

The angular shape of square bracket characters is a good reminder of verbatim
texts' aspect (separate block, monospace font). The usage of opening and closing
square brackets is perfect to mark the block's boundaries.
</div>
<h2 id="code">15. Code</h2>
<p>
As for verbatim text, Skriv syntax is not interpreted inside code blocks.
The difference between a verbatim text block and a code block is the presence
of the programming language's name after the three opening square brackets
(there could be spaces between the brackets and the language's name, but it's
not a mandatory).

Since code blocks content is not interpreted, they are only a special case of verbatim text blocks.
So it's logical to keep usage of triple-square brackets.
</p>
<p>
Code blocks are rendered as a <tt>&lt;code&gt;</tt> inside a <tt>&lt;pre&gt;</tt> tag, because it's the
<a href="http://dev.w3.org/html5/spec-author-view/the-code-element.html#the-code-element" target="_blank">recommended

This syntax is a convenient way to apply some CSS styles to paragraphs. Styled blocks are
written between triple-curly brackets (<tt>{{{ }}}</tt>). All paragraphs
inside will inherit the specified styles. CSS classes are typed just after the opening brackets.
</p>
<p>
It is possible to nest styled paragraphs. Just add triple-curly brackets-enclosed blocks inside
existing ones. For a better readability, you can add any number of spaces and/or curly brackets
before the CSS class names; the sole obligation is to start the lines with three opening curly
brackets and three closing curly brackets.

<h2 id="extensions">18. Extensions</h2>
<p>
Skriv Markup has an extension mechanism, designed to add new features to the language without
modifying its basic syntax. Extensions may also be called “plugins”.
</p>
<p>
Extensions are validated before becoming a part of the official Skriv Markup syntax. Official extensions
SHOULD be available in any Skriv Markup implementation, but they COULD be deactivated at will.<br />
Unofficial extensions MAY be activated at will.
</p>
<p>
Look at the <a href="https://markup.skriv.org/language/extensions">page about extensions</a> to get the list of validated plugins.
</p>
<h3 id="extensions-inline">18.1 Inline</h3>
<p>
Inline extensions are written using double-angle brackets (<tt>&lt;&lt; &gt;&gt;</tt>). The extension's
name must be written just after the opening brackets. If the plugin needs some parameters, they are
added just after, separated by pipe (<tt>|</tt>) characters.
</p>
<p>
Here is an example plugin, which goal is to insert the given number of “lorem ipsum” paragraphs.
</p>
<div class="label">Skriv Markup</div>
<pre><b class="red">&lt;&lt;</b><b class="blue">lipsum</b><b class="red">|</b>2<b class="red">&gt;&gt;</b></pre>
<div class="label">HTML</div>
<pre>&lt;p&gt;
Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque leo sem,
commodo quis tempus luctus, tempor vel libero. Phasellus rutrum ipsum accumsan
mauris gravida nec ultricies ante mattis. Ut et nibh neque.
&lt;/p&gt;
&lt;p&gt;
Praesent pulvinar rhoncus tincidunt. Ut eleifend sollicitudin nibh sed
porttitor. In hac habitasse platea dictumst. Etiam bibendum mi id ligula
blandit pulvinar et quis neque. Duis sagittis tempus tellus at rutrum.
&lt;/p&gt;</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
Angle brackets are not used for any other element of the Skriv Markup syntax.
However, they are immediately identified as special markup, because of their usage in HTML.
</div>
<h3 id="extensions-block">18.2 Block</h3>
<p>
Block extensions are very similar to inline ones. They are delimited by triple-angle brackets
(<tt>&lt;&lt;&lt; &gt;&gt;&gt;</tt>), with the name and possible options just behind the opening
brackets.
</p>
<p>
Here is an example plugin, which translates the given text. The first parameter is the input language,
the second parameter is the output language.
</p>
<div class="label">Skriv Markup</div>
<pre><b class="red">&lt;&lt;&lt;</b><b class="blue">translate</b><b class="red">|</b>french<b class="red">|</b>english
écrire, travailler, organiser
<b class="red">&gt;&gt;&gt;</b></pre>
<div class="label">HTML</div>
<pre>&lt;p&gt;
write, work, organize
&lt;/p&gt;</pre>
<div class="label label-info">Reasoning</div>
<div class="alert alert-info">
Same reasoning than for inline extensions. Triple-characters are used for blocks as usual.
