Abstract

An application development editor displays in a graphical user interface a list or other arrangement of variations based on or applying to conditions in the application, each variation being associated with one or more changes in properties or events in the application. The editor enables a user to select a specific variation and then displays the user interface implications or consequences of that selection. Selecting a specific variation is programmatically equivalent to a specific conditional logic branch or ‘if . . . then’ code sequence. The invention enable someone with no, or very limited, code writing skills, such as a designer, to be able to produce an application with fully functioning, correct and potentially complex conditional logic.

Claims

1. A processor implemented method for rapid software application development comprising the steps of:

(a) using a declarative textual language as an internal representation of a software application, wherein the declarative textual language encodes pages, a hierarchy of components, properties and variations, the representation including a scene tree, in which the representation is fully defined with no unknown states, wherein the declarative textual language is strongly typed, the declarative textual language including base types and base classes, object types and visual object types, the declarative textual language allowing new types to be statically declared based on the base classes, wherein the declarative textual language is not a Turing complete language;

(b) displaying in a graphical user interface (GUI) of a software application development editor a list of variations based on or applying to conditions in the software application, each variation being associated with one or more changes in properties or events in the software application, and each variation being a statically declared non-ambiguous state;

(c) enabling a user to select a specific variation, and receiving a user selection of the specific variation, and including the selected specific variation into the declarative textual language internal representation of the software application;

(d) an engine reading the declarative textual language internal representation of the software application, including reading the scene tree representation, to simulate runtime behavior of the software application to display, in the graphical user interface, the user interface implications or consequences of the selection;

and in which the operations of the method are executed by a processor.

2. The method of claim 1 in which the GUI displays all of the possible variable states of the application in one place, on a page by page basis for each page or screen of the application.

3. The method of claim 1 in which the GUI includes items selectable from a menu.

4. The method of claim 1 in which the GUI includes a visual checklist.

5. The method of claim 1 in which the variations are executed top to bottom in the list.

6. The method of claim 1 in which visual flags are provided for a user to visually see if a variation has been applied in the editor and to see if the user has tested their application for all possible variations.

7. The method of claim 1 in which selecting a specific variation automatically results in consequential changes to hierarchically related parameters or variables.

8. The method of claim 1 in which the variation applies to the following condition in the application:

Region.

9. The method of claim 1 in which the variation applies to the following condition in the application:

Language.

10. The method of claim 1 in which the variation applies to the following condition in the application:

OS (operating system).

11. The method of claim 1 in which the variation applies to the following condition in the application:

Orientation, wherein the Orientation condition includes a selection of landscape or portrait.

12. The method of claim 1 in which the variation applies to the following condition in the application:

Device type, wherein the Device type condition includes a selection of watch, phone, tablet, computer, or TV.

13. The method of claim 1 in which the variation applies to the following condition in the application:

a selection of pixel density.

14. The method of claim 1 in which the variation applies to the following condition in the application:

a selection of Manufacturer &

device model.

15. The method of claim 1 in which the variation applies to the following condition in the application:

Custom, wherein the Custom condition includes a selection of user defined flags.

16. The method of claim 1 in which the application is represented in a language in which objects have multiple named states, where one or more properties or actions can be over-ridden.

17. The method of claim 1 in which variations apply to a target, or to a target object, or to a target master-object, or to a target region.

18. The method of claim 1 in which variations apply changes to the layout of a page or a masterpage, wherein the masterpage is one from which multiple pages can be subclassed.

19. The method of claim 1 in which variations allow modifications to control regions and other objects or masterobjects, wherein a masterobject is one from which multiple objects can be subclassed, contained on each page.

20. The method of claim 1 in which variations on an object can either set a property or override an event, where the event can have a different list of actions.

21. The method of claim 1 in which the conditions are evaluated upon startup and after changes to any of the conditions'"'"' attributes.

22. The method of claim 1 in which the conditions are evaluated in order and each condition maintains a state of how it has been applied so that it is applied the first time the condition matches and it is correctly reset when the condition stops matching.

23. The method of claim 1 in which the editor enables a user to create lists of variations or alterations to defined targets, depending on the applicable conditions in order to specify detailed design, layout or behavioural changes.

24. The method of claim 1 in which a variation creates a custom action, allowing actions to be overridden for a specific variation.

25. The method of claim 1 in which the engine manages rendering of visual objects.

26. The method of claim 1 in which the engine also raises events, handles message passing, processes any animations and processes any equivalences.

27. A software application developed using a processor implementing a method for rapid software application development, the software application embodied on a non-transitory storage medium, the processor configured to:

(a) use a declarative textual language as an internal representation of a software application, wherein the declarative textual language encodes pages, a hierarchy of components, properties and variations, the representation including a scene tree, in which the representation is fully defined with no unknown states, wherein the declarative textual language is strongly typed, the declarative textual language including base types and base classes, object types and visual object types, the declarative textual language allowing new types to be statically declared based on the base classes, wherein the declarative textual language is not a Turing complete language;

(b) display in a graphical user interface (GUI) of a software application development editor a list of variations based on or applying to conditions in the software application, each variation being associated with one or more changes in properties or events in the software application, and each variation being a statically declared non-ambiguous state;

(c) enable a user to select a specific variation, and to receive a user selection of the specific variation, and to include the selected specific variation into the declarative textual language internal representation of the software application; and

(d) execute an engine reading the declarative textual language internal representation of the software application, including reading the scene tree representation, to simulate runtime behavior of the application to display, in the graphical user interface, the user interface implications or consequences of that selection.

28. A system for rapid software application development comprising a processor and a software application development editor embodied on a non-transitory storage medium and executable on the processor, wherein the processor is programmed to use a declarative textual language as an internal representation of a software application, wherein the declarative textual language encodes pages, a hierarchy of components, properties and variations, the representation including a scene tree, in which the representation is fully defined with no unknown states, wherein the declarative textual language is strongly typed, the declarative textual language including base types and base classes, object types and visual object types, the declarative textual language allowing new types to be statically declared based on the base classes, wherein the declarative textual language is not a Turing complete language;

to display in a graphical user interface (GUI) a list of variations that are based on or applying to conditions in the software application, each variation being associated with one or more changes in properties or events in the software application, and each variation being a statically declared non-ambiguous state;

wherein the processor is further programmed to enable a user to select a specific variation, to receive a user selection of the specific variation, and to include the selected specific variation into the declarative textual language internal representation of the software application; and

to execute an engine reading the declarative textual language internal representation of the software application, including reading the scene tree representation, to simulate runtime behavior of the software application to display, in the graphical user interface, the user interface implications or consequences of that selection.
