Obviously, this is supposed to work only for code blocks (<pre><code>) and not for inline code.
Add the line-numbers class to your desired <pre> or any of its ancestors, and the line-numbers plugin will take care of the rest. To give all code blocks line numbers, add the line-numbers class to the <body> of the page.
Add the line-numbers class to your desired <pre> or any of its ancestors, and the Line Numbers plugin will take care of the rest. To give all code blocks line numbers, add the line-numbers class to the <body> of the page. This is part of a general activation mechanism where adding the line-numbers (or no-line-numbers) class to any element will enable (or disable) the Line Numbers plugin for all code blocks in that element.
Example:
<body class="line-number"> <!-- enabled for the whole page -->
+
+ <!-- with line numbers -->
+ <pre><code>...</code></pre>
+ <!-- disabled for a specific element - without line numbers -->
+ <pre class="no-line-numbers"><code>...</code></pre>
+
+ <div class="no-line-numbers"> <!-- disabled for this subtree -->
+
+ <!-- without line numbers -->
+ <pre><code>...</code></pre>
+ <!-- enabled for a specific element - with line numbers -->
+ <pre class="line-number"><code>...</code></pre>
+
+ </div>
+</body>Optional: You can specify the data-start (Number) attribute on the <pre> element. It will shift the line counter.
Optional: To support multiline line numbers using soft wrap, apply the CSS white-space: pre-line; or white-space: pre-wrap; to your desired <pre>.
