I have problem with <pre>, here is my code, and the screenshot is attached below. How to remove the indents?
%pre.code
:escaped
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-tr开发者_运维技巧ansitional.dtd">
<html>
<head></head>
<body>
<form>
<input type="text" name="empID" />
<input type="submit"/>
</form>
</body>
</html>
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.
When representing "pre" like text from a variable inside a div or other tag, use
.text.plain= preserve(@mail.body.to_s)
along with CSS "white-space: pre-wrap;". Use the one-line version, because the two-line will still indent the first line.
/ BAD: Will leave the first line incorrectly indented!
.text.plain
= preserve(@mail.body.to_s)
