							<p>Glyph is a <em>Rapid Document Authoring Framework</em>.</p>
<p>With Glyph, creating and maintaining any kind of document becomes as easy as&#8230; <em>programming</em>. Glyph enables you to minimize text duplication, focus on content rather than presentation, manage references seamlessly and automate tedious tasks through a simple but effective macro language, specifically geared towards customization and extensibility.</p>
<p><br style="clear:both" /></p>
<div class="section">
<h3 id="h_2">Main Features</h3>
<div class="section">
<h4 id="h_3">Command Line Interface</h4>
<p>Glyph is 100% command line. Its interface resambles <a href="http://git-scm.com/">Git&#8217;s</a> for its simplicity and power (thanks to the <a href="http://github.com/davetron5000/gli">gli</a> gem). Here are some example commands:</p>
<ul>
	<li><code>glyph init</code> &#8212; to initialize a new Glyph project in the current (empty) directory.</li>
	<li><code>glyph add introduction.textile</code> &#8212; to create a new file called <em>introduction.textile</em>.</li>
	<li><code>glyph compile</code> &#8212; to compile the current document into a single <span class="caps">HTML</span> file.</li>
	<li><code>glyph compile --auto</code> &#8212; to keep recompiling the current document every time a file is changed.</li>
	<li><code>glyph compile -f pdf</code> &#8212; to compile the current document into <span class="caps">HTML</span> and then transform it into <span class="caps">PDF</span>.</li>
	<li><code>glyph compile readme.glyph</code> &#8212; to compile a <em>readme.glyph</em> located in the current directory into a single <span class="caps">HTML</span> file.</li>
	<li><code>glyph outline -l 2</code> &#8212; Display the document outline, up to second-level headers.</li>
	<li><code>glyph stats</code> &#8212; Display project statistics.</li>
</ul>
</div>
<div class="section">
<h4 id="h_4">Minimalist Syntax</h4>
<p>Glyph syntax rules can be explained using Glyph itself:</p>
<div class="code">
<pre>
<code>
section[
  @title[Something about Glyph]
  txt[
You can use Glyph macros in conjunction 
with _Textile_ or _Markdown_ to
produce HTML files effortlessly.
  ]
  p[Alternatively, you can just use em[Glyph itself] to generate HTML tags.]
  section[
    @title[What about PDFs?]
    @id[pdf]
    p[
Once you have a single, well-formatted HTML 
file, converting it to PDF is
extremely easy with a free 3rd-party 
renderer like =&gt;[http://www.princexml.com|Prince] 
or =&gt;[http://code.google.com/p/wkhtmltopdf/|wkhtmltopdf].
    ]
  ]   
]
</code>
</pre>
</div>
<p>The Glyph code above corresponds to the following <span class="caps">HTML</span> code:</p>
<div class="code">
<pre>
<code>
&lt;div class="section"&gt;
  &lt;h2 id="h_10"&gt;Something about Glyph&lt;/h2&gt;
  &lt;p&gt;
    You can use Glyph macros in conjunction with 
    &lt;em&gt;Textile&lt;/em&gt; or &lt;em&gt;Markdown&lt;/em&gt; to
    produce HTML files effortlessly.
  &lt;/p&gt;
  &lt;p&gt;
    Alternatively, you can just use &lt;em&gt;Glyph itself&lt;/em&gt;
    to generate HTML tags.
  &lt;/p&gt;
  &lt;div class="section"&gt;
   &lt;h3 id="pdf"&gt;What about PDFs?&lt;/h3&gt;
   &lt;p&gt;
     Once you have a single, well-formatted HTML 
     file, converting it to PDF is
     extremely easy with a free 3rd-party renderer 
     like &lt;a href="http://www.princexml.com"&gt;Prince&lt;/a&gt; 
     or &lt;a href="http://code.google.com/p/wkhtmltopdf/\"&gt;wkhtmltopdf&lt;/a&gt;.
   &lt;/p&gt;
  &lt;/div&gt;
&lt;/div&gt;
</code>
</pre>
</div>
</div>
<div class="section">
<h4 id="h_5">Content Reuse</h4>
<p>Finding yourself repeating the same sentence over an over? Glyph allows you to create snippets. Within snippets. Within other snippets (and so on, for a long long time&#8230;) as long as you don&#8217;t define a snippet by defining itself, which would be kinda nasty (and Glyph would complain!):</p>
<div class="code">
<pre>
<code>
snippet:[entities|snippets and macros]
snippet:[custom_definitions|
	p[Glyph allows you to define your own &amp;[entities].]
]
&amp;[custom_definitions]
</code>
</pre>
</div>
<p>&#8230;which results in:</p>
<div class="code">
<pre>
<code>
&lt;p&gt;Glyph allows you to define your own snippets and macros.&lt;/p&gt;
</code>
</pre>
</div>
<p>If yourself dreaming about <em>parametric</em> snippets, just create your own macros (see the <a href="http://github.com/h3rald/glyph/blob/master/book/text/changelog.glyph">source</a> of Glyph&#8217;s changelog, just to have an idea).</p>
</div>
<div class="section">
<h4 id="h_6">Automation of Common Tasks</h4>
<p>If you&#8217;re writing a book, you shouldn&#8217;t have to worry about pagination, headers, footers, table of contents, section numbering or similar. Glyph understands you, and will take care of everything for you (with a little help from CSS3, sometimes).</p>
</div>
<div class="section">
<h4 id="h_7">Reference Validation</h4>
<p>Feel free to add plenty of links, snippets, bookmarks, &#8230; if Glyph doesn&#8217;t find something, it will definitely complain. Broken references are a thing on the past, and you don&#8217;t need to worry about it.</p>
</div>
<div class="section">
<h4 id="h_8">Extreme Extensibility</h4>
<ul>
	<li>You miss a <code>!!!</code> macro to format really, <em>really</em> important things? Create it. In under 3 seconds, in Ruby or Glyph itself. And yes, you can use special characters, too.</li>
	<li>You want your own, very special special <code>glyph create --everything</code> command to create all <em>you</em> need in a Glyph project? You can do it. Using your own Rake tasks, too.</li>
	<li>You want Glyph to output <span class="caps">ODF</span> files? You can do it, and you&#8217;ll be able to run <code>glyph generate -f odf</code>. This would probably require a little more time, but it&#8217;s trivial, from a technical point of view.</li>
</ul>
</div>
<div class="section">
<h4 id="h_9">Convention over Configuration</h4>
<p>Put your text files in <code>/text</code>, your images in <code>/images</code>, add custom macros in a <code>macro</code> folder within your <code>/lib</code> folder&#8230; you get the picture: Glyph has its special places.</p>
<p>Nonetheless, you also have 1 (<em>one</em>) configuration file to customize to your heart&#8217;s content (with smart defaults).</p>
</div>
<div class="section">
<h4 id="h_10">Free and Open Source</h4>
<p>Glyph is 100% Open Source Software, developed using the Ruby Programming Language and licensed under the very permissive terms of the <a href="http://www.opensource.org/licenses/mit-license.php"><span class="caps">MIT</span> License</a>.</p>
<p>If you have Ruby installed, just run <code>gem install glyph</code>. That&#8217;s all it takes.</p>
