 # purescript-openlayers
 A purescript FFI binding for OpenLayers v6.5. It is by no means near a complete binding but fulfills the need for the Swedish IoT Hub Prototype for Accessibility Case 3, see https://github.com/dnulnets/haccessibility, for now. Please feel free to contribute to thie library!
 
+
+Version 0.2 supports purescript 0.14.
+
+
 OpenLayers uses a lot of object inheritance, optional record fields and fields having mutiple types when creating the objects. It has been solved in purescript by using type parameters, Union, and a pattern of constructuor records and unsafeCoerce. See below for more details.

-All javascript ***new*** functions in OpenLayers are mapped to a correspondign ***create*** function for each class. The case when the options parameter for the javascript ***new*** function can be omitted completely a ***create'*** function is added.
