Hiccup is a library for representing HTML in Clojure. It uses vectors to represent elements, and maps to represent an element's attributes.
Add the following dependency to your project.clj
file:
[hiccup "1.0.1"]
Here is a basic example of Hiccup syntax:
user=> (use 'hiccup.core)
nil
user=> (html [:span {:class "foo"} "bar"])
"<span class=\"foo\">bar</span>"
The first element of the vector is used as the element name. The second attribute can optionally be a map, in which case it is used to supply the element's attributes. Every other element is considered part of the tag's body.
Hiccup is intelligent enough to render different HTML elements in different ways, in order to accommodate browser quirks:
user=> (html [:script])
"<script></script>"
user=> (html [:p])
"<p />"
And provides a CSS-like shortcut for denoting id
and class
attributes:
user=> (html [:div#foo.bar.baz "bang"])
"<div id=\"foo\" class=\"bar baz\">bang</div>"
If the body of the element is a seq, its contents will be expanded out
into the element body. This makes working with forms like map
and
for
more convenient:
user=> (html [:ul
(for [x (range 1 4)]
[:li x])])
"<ul><li>1</li><li>2</li><li>3</li></ul>"
