Utilities for working with hiccup forms.

class-names clj/s

(class-names tag-elem)

Given a well-formed hiccup tag element, return a vector containing any class names included in the tag, as strings. Ignores the hiccup requirement that any id on the tag must come first. Example: :div.foo.bar => ["foo" "bar"].

id clj/s

(id tag-elem)

Given a well-formed hiccup tag element, return a string containing the id, or nil if there isn't one.

normalize-form clj/s

(normalize-form form)

Given a well-formed hiccup form, recursively normalizes it, so that it and all children elements will also be normalized. A normalized form is in the form [tag attributes content1 ... contentN]. That is, an unadorned tag name (keyword, lowercase), all attributes in the attribute map in the second element, and then any children. Any content that is a sequence is also expanded out into the main sequence of content items.

tag-name clj/s

(tag-name tag-elem)

Given a well-formed hiccup tag element, return just the tag name as a string.

tag-well-formed? clj/s

(tag-well-formed? tag-elem)

Given a hiccup tag element, returns true iff the tag is in 'valid' hiccup format. Which in this function means:

1. Tag name is non-empty.
2. If there is an id, there is only one.
3. If there is an id, it is nonempty.
4. If there is an id, it comes before any classes.
5. Any class name is nonempty.
