v0.4.0 (2018-10-16)

This release comes with some refactorings of the public API to make it easier to use.
Most prominently, annotation based autogenerator for exposing object properties to the Crinja runtime were added.

require "crinja"

class User
  include Crinja::Object::Auto

  @[Crinja::Attribute]
  def name : String
    "john paul"
  end
end

Crinja.new.from_string("{{ user.name }}").render({"user" => User.new}) # => "john paul"

Autogeneration of crinja_call will be left for the next release.

Most other changes involve the CI infrastructure, with Circle CI taking over the main load from travis.

• (breaking-change) Replaced Crinja::PyObject by Crinja::Object and renamed hook methods to crinja_attribute and crinja_call. getitem hook has been removed.
• (breaking-change) Added Crinja::Object::Auto for generating automatic bindings for crinja_attribute (previously provided by Crinja::PyObject.getattr). The behaviour can be configured using annotations Crinja::Attribute and Crinja::Attributes.
• (breaking-change) Renamed Crinja::Callable::Arguments to Crinja::Arguments. The API has been simplified by removing unused setters.
• (breaking-change) Removed Crinja::Arguments#[](key : Symbol). Use a string key instead.
