You need to use the #preserve
helper to convert the newlines in the pre
to newline entities, like so:
%pre.code
= preserve do
:escaped
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head></head>
<body>
<form>
<input type="text" name="empID" />
<input type="submit"/>
</form>
</body>
</html>
In the future, you’ll be able to nest filters, so you can do :preserve:escaped
.
