• Prefer fixed indentation for multi-line arguments
• Allow positional args on first line, keywords on next lines
• Prefer consistent indent in array literals
• Prefer indenting method chains relative to receiver
• Allow skipping model validations

Rename ApplicationForm's @action and @method to @default_action, @default_method for consistency

Exclude namespaces in form's model_name, because when you want to alter a form's action you can do it this way:

class MyPage < ApplicationStruct
  class MyForm < ::MyForm
    action Urls.different_than_in_superclass
  end

  keyword :form, default: proc { MyForm.new }
end

And you will still be getting my_form in your params, instead of my_page_my_form.

Fix Rails compatibility bug in ApplicationForm#as_json

Add ApplicationForm.param_key (returning model_name.param_key) for convenience

Add ApplicationForm.===. This allows the following:

case params
when SomeForm
  # do something
when SomeOtherForm
  # do something else
end

Or simply:

if SomeForm === params
  # do something
end

Allow passing additional keywords in ApplicationForm.from_params and FlashMessages.from_flash
