This however comes with a price: because square brackets are used as delimiters, you must escape any square bracket in your text with a backslash. That’s not <em>too</em> bad if you think about it, unless you’re writing programming code, in which case escaping every single square bracket can be painful.</p> <p>If a portion of your text contains an excessive amount of square brackets, you may consider using the <a href="/glyph/book/macros/macros_core.html#m_escape"><code>escape</code></a> macro (or its alias <code>.</code>) with the <code>[=</code> and <code>=]</code> delimiters. By itself, the escape macro doesn’t do anything: it just evaluates to its contents, but the special delimiters act as an escape for any square bracket within them. As a consequence, any macro within <code>[=</code> and <code>=]</code> will <em>not</em> be evaluated.</p> <p>You can use the quoting delimiters with <em>any</em> macro identifier. Obviously, using them as delimiters for things like <a href="/glyph/book/macros/macros_structure.html#m_section"><code>section</code></a> macros may not be a good idea, but they should be more or less mandatory with the <a href="/glyph/book/macros/macros_block.html#m_codeblock"><code>codeblock</code></a> macro or the <a href="/glyph/book/macros/macros_filters.html#m_highlight"><code>highlight</code></a> macro, especially when it contains square brackets or even Glyph code, like this:</p> <pre class="lazy"><span class="line-numbers"> 1 </span> codeblock[= <span class="line-numbers"> 2 </span> section[ <span class="line-numbers"> 3 </span> @title[A section] <span class="line-numbers"> 4 </span> @id[test] <span class="line-numbers"> 5 </span> This is a section. <span class="line-numbers"> 6 </span> section[ <span class="line-numbers"> 7 </span> @title[A nested section] <span class="line-numbers"> 8 </span> This is another section. <span class="line-numbers"> 9 </span> ] <span class="line-numbers"> 10 </span> ] <span class="line-numbers"> 11 </span> =] </pre> <div class="note"> <span class="note-title">Note</span>Although quoting delimiters allow you to use square brackets without escaping them, you must still escape them if you want to escape quoting delimiters themselves. </div> <p>Besides square brackets, there are other characters that must or can be escaped with backslashes, as shown in the following table:</p> <table><tr><th>Escape Sequence</th> <th>Evaluates to...</th> <th>Notes</th></tr> <tr><td> <code>[</code> </td> <td> <code>[</code> </td> <td>Square brackets must be escaped unless used as macro delimiters or within a quoting macro.</td></tr> <tr><td> <code>]</code> </td> <td> <code>]</code> </td> <td>Square brackets must be escaped unless used as macro delimiters or within a quoting macro.</td></tr> <tr><td> <code>\</code> </td> <td> <code>\</code> </td> <td>Backslashes do not have to be escaped by default, but an escaped backslash will evaluate to itself.</td></tr> <tr><td> <code>=</code> </td> <td> <code>=</code> </td> <td>Equal signs do not have to be escaped by default, but an escaped equal sign will evaluate to iself.</td></tr> <tr><td> <code>|</code> </td> <td> <code>|</code> </td> <td>Pipes must be escaped (even within quoting macros) unless they are used to separate macro parameters.</td></tr> <tr><td> <code></code> </td> <td /> <td>An escaped dot evaluates to nothing.
