For this reason, Glyph provides an <a href="/glyph/book/macros/macros_core.html#m_include"><code>include</code></a> macro that can be used to include the contents of any file within the <code>text/</code> directory:</p> <p><code>include[general/introduction.textile]</code></p> <p>The macro call above loads the contents of the <code>introduction.textile</code> file, within the <code>text/general</code> directory.</p> <p>When including a text file, an input filter macro is applied to its contents by default, based on the file extension used:</p> <ul> <li><code>.textile</code> or <code>.txt</code> → <a href="/glyph/book/macros/macros_filters.html#m_textile"><code>textile</code></a> macro</li> <li><code>.markdown</code> or <code>.md</code> → <a href="/glyph/book/macros/macros_filters.html#m_markdown"><code>markdown</code></a> macro</li> </ul> <p>You can override this behavior by setting the <code>filters.by_file_extensions</code> configuration setting to <code>false</code>. If no extension is specified, <code>.glyph</code> is assumed.</p> <div class="tip"> <p><span class="note-title">Tip</span>The <a href="/glyph/book/macros/macros_core.html#m_include"><code>include</code></a> macro can also be used to include (and evaluate) ruby files (with a <code>.rb</code> extension). In this case, the ruby file must be placed within the <code>lib/</code> directory of the current project.</p> </div> <p>While including the context of an entire file is definitely a useful feature for content reuse, sometimes it can be an overkill. What if, for example, you just want to reuse a short procedure or even a sentence or a single word? In this case, you may want to consider using a <em>snippet</em> instead.</p> <p>Snippets are text strings saved in <span class="caps">YAML</span> format in the <code>snippets.yml</code> file. They can be included anywhere in your document using the <a href="/glyph/book/macros/macros_core.html#m_snippet"><code>snippet</code></a> macro (or its alias <code>&</code>).</p> <div class="tip"> <p><span class="note-title">Tip</span>Besides storing snippets in the <code>snippets.yml</code> file, you can also define them right in your document, using the <a href="/glyph/book/macros/macros_core.html#m_snippet_"><code>snippet:</code></a> macro.</p> </div> <div class="box"> <div class="box-title">Example</div> <p>Consider the following <code>snippets.yml</code> file:</p> <pre class="lazy"><span class="line-numbers"> 1 </span> <span class="Keyword">-</span><span class="Keyword">-</span><span class="Keyword">-</span><span class="InvalidDeprecated"> </span> <span class="line-numbers"> 2 </span> :<span class="String"><span class="Entity">glang<span class="Entity">:</span></span> <span class="String">Glyph Language</span></span> <span class="line-numbers"> 3 </span> :<span class="String"><span class="Entity">macros<span class="Entity">:</span></span> <span class="String">Glyph Macros</span></span> <span class="line-numbers"> 4 </span> :<span class="MetaTag"><span class="MetaTag">sq_esc</span><span class="MetaTag">:</span> </span>|<span class="Keyword">-</span> <span class="line-numbers"> 5 </span> Square brackets must be escaped<span class="InvalidDeprecated"> </span> <span class="line-numbers"> 6 </span> unless used as macro delimiters or within a quoting macro. <span class="line-numbers"> 7 </span> :<span class="String"><span class="Entity">markups<span class="Entity">:</span></span> <span class="String">Textile or Markdown</span></span> <span class="line-numbers"> 8 </span> :<span class="MetaTag"><span class="MetaTag">test</span><span class="MetaTag">:</span> </span>|<span class="Keyword">-</span> <span class="line-numbers"> 9 </span> This is a<span class="InvalidDeprecated"> </span> <span class="line-numbers"> 10 </span> Test snippet </pre> <p>You can use <code>&[markups]</code> anywhere in your document instead of having to type "Textile or Markdown" every time. Additionally, later on you can change the value of the <code>markups</code> snippet only in the <code>snippets.yml</code> file to change it everywhere else in the document.</p> </div> <div class="tip"> <span class="note-title">Tip</span>Snippets (or any other macro) can be nested within other snippets.
