Metrics overview

Lines (HTML)

API ID: CountLineHtml
Languages: Web
Targets: Architectures, Files, Project

Number of all HTML lines.

Counts every line of an HTML file that isn't inside an embedded sub-language block, including the tag lines that open and close those blocks (such as <script>/</script>).

For example:


<!DOCTYPE html>
<html>
<head>
  <title>Welcome</title>

  <!-- Greeting script: tracks visits and confirms with the user -->
  <script>
    // Number of times the page has greeted someone
    var greetingCount = 0;

    function greetUser(name) {
      greetingCount++;
      return "Hello, " + name + "!";
    }

    let message = greetUser("Ada");
    console.log(message);

    if (greetingCount > 0) {
      confirm(message);
    }
  </script>
</head>
<body>
  <h1>Welcome to the site</h1>
  <p>Have a look around.</p>
</body>
</html>

sample.html is 28 lines total. The <script> block's contents (lines 8-21) are JavaScript, but the <script> (7) and </script> (22) tag lines themselves still count as HTML, along with the rest of the page (1-6, 23-28), giving CountLineHtml = 14.

See Lines (JavaScript) for the embedded script's contents, and Blank Lines (HTML)/Comment Lines (HTML) for the HTML breakdown. See Lines for the language-independent total across the whole file.
