escape_link
Convert any URLs in a plaintext into HTML links, with adding the
rel="nofollow" attribute, and replaces all newlines with <br> tags.
Example:
{{ "Hello http://foo.bar/\n\nAnd bye."|escape_link }}
Outputs:
"Hello <a href="http://foo.bar/" rel="noopener nofollow noreferrer">http://foo.bar/</a><br /><br />And bye."
This filter is very useful when displaying user-generated plaintexts, like comments.
