Maybe check if there is an updated version on MacroMarket (or an
alternative). Gallery2 or Arnica comes to my mind (but I personally
don't use that stuff).

request is available as macro.request.

For accessing the URL args (query string), use request.args.

For accessing POST form data, use request.form.

If you want both mixed because you don't care, use request.values.

All these are werkzeug MultiDicts and if you just want to get the first
value for some key, you can use e.g. request.values.get("somekey",
"defaultvalue"). No need for [0] or ["defaultvalue"].

These changes were due to wsgi/werkzeug refactoring, you can also just
have a look into the macros we have in 1.9.x to see how they work now.
