Clojurians Log v2

If it still works, I'd just keep using it.

It doesn't parse HTML.

I’m not sure what this has to do with hiccup.core vs hiccup2.core

The former is deprecated and the latter is suggested to be used instead. But the latter doesn't have all the features of the former. Namely, parsing.

Since when did hiccup have an HTML parser?

Oh, oops. Just woke up. :)

1. hiccup.core is deprecated! 2. hiccup2.core doesn't roundtrip nicely with hickory.core/parse and as-hiccup any more, as it hiccup2's raw string behavior is to escape the HTML. My question was motivated by the fact that html string -> hiccup -> hiccup transformer -> hiccup -> string seems like a reasonable thing to want to do.

Enlive is good at this sort of thing - the parsing, the transformation, and the output- but it uses clojure.xml format, not hiccup, for the working structure. (and masterful use of zippers for modification)

Or just use hickory.core/as-hiccup2. There might be such a thing and if not, you could contribute it

The addition of escaping to hiccup was such a good thing that it seems reasonable the adapters-to-hiccup would happily cooperate

You can unescape HTML with hiccup2, just be explicit about it

See docs

I would provide the link but on phone

I can provide, i have computer

hiccup2.core/html
[options & content]
Macro
Added in 2.0
  Render Clojure data structures to a compiled representation of HTML. To turn
  the representation into a string, use clojure.core/str. Strings inside the
  macro are automatically HTML-escaped. To insert a string without it being
  escaped, use the raw function.

  A literal option map may be specified as the first argument. It accepts two
  keys that control how the HTML is outputted:

  :mode
  : One of :html, :xhtml, :xml or :sgml (defaults to :xhtml).
    Controls how tags are rendered.

  :escape-strings?
  : True if strings should be escaped (defaults to true).

hiccup2.core/html is defined in 
hiccup2/core.clj.

Use the raw function

Or escape strings false

This did the trick:

(defn alter-response-hiccup [{:as response :keys [body]} f]
  (assoc response :body (str (hiccup2.core/html {:escape-strings? false}
                               (-> body hickory.core/parse hickory.core/as-hiccup f)))))
