Abstract

The present invention discloses a system for using a single description document to automatically generate user interface (UI) code for multiple operating environments. Such a system can include a configuration description document, one or more target operating environment code generators, and a UI generation engine. The configuration description document can define UI elements using a standardized meta-language and a declaratively-specified configuration model. The target operating environment code generators can generate software code from the configuration description document that is specific to a target operating environment. The user interface generation engine can receive the configuration description document as input and automatically execute the target operating environment code generators.

Claims

1. A system for automatically generating user interface (UI) code for multiple operating environments from a single description document comprising:

a configuration description document that defines one or more elements of a user interface (UI), wherein the configuration description document is written using a standardized meta-language and a declaratively-specified configuration model;

a plurality of target operating environment code generators, each configured to generate a set of machine-readable instructions specific to a target operating environment based upon the configuration description document; and

a user interface generation engine configured to receive the configuration description document and automatically execute at least one of the target operating environment code generators, each of which results in a production of executable interface code.

2. The system of claim 1, wherein the configuration description document is written in an extensible markup language (XML) in accordance with a user interface markup language (UIML).

3. The system of claim 1, wherein the configuration description document contains processing logic, wherein the processing logic dictates a presentation of a specified UI element based upon a user-inputted value for at least one previously displayed element.

4. The system of claim 1, wherein the configuration description document contains a default value for the one or more UI elements.

5. The system of claim 1, wherein said components of claim 1 are utilized within a software development environment.

6. The system of claim 1, wherein the target operating environment is at least one of a Web-based environment, a widget-based environment, and a command-line environment.

7. The system of claim 1, further comprising:

an interface configured to allow configuration of the UI generation engine.

8. The system of claim 1, wherein the target operating environment code generators are extensible, wherein an addition of a new code generator results in an ability to generate interface code for a new target operating environment corresponding to the new code generator.

9. A method for automatically generating user interface (UI) code for multiple operating environments from a single description document comprising:

authoring a configuration description document, wherein the configuration description document is a meta-language document that defines elements of a user interface (UI) in accordance with a declaratively-specified configuration model;

determining at least one target operating environment for which interface code is to be generated;

conveying the configuration description document to a UI generation engine, wherein the UI generation engine contains a plurality of target operating environment code generators, said plurality of code generators including a code generator corresponding to each of the determined target operating environments of the determining step;

selecting a code generator for each of said at least one determined target operating environment; and

for each selected code generator, the UI generation engine automatically generating a set of software code files that corresponds to a corresponding one of the determined target operating environments, said set of software code comprising interface code for the target operating environment.

10. The method of claim 9, wherein the at least one determined target operating environment comprises a plurality of target operating environments, whereby a set of software code files is generated by the method for each of the target operating environments based upon the same configuration description document.

11. The method of claim 9, wherein the declaratively-specified configuration model is a user interface markup language (UIML).

12. The method of claim 9, wherein the meta-language is an extensible markup language (XML).

13. The method of claim 9, wherein the target operating environment is at least one of a Web-based environment, a widget-based environment, and a command-line environment.

14. The method of claim 9, wherein said steps of claim 9 are executed within a software development environment.

15. The method of claim 9, wherein the one or more target operating environment code generators used by the UI generation engine to generate the code files are selectable by a user.

16. The method of claim 9, wherein said steps of claim 9 are performed by at least one machine in accordance with at least one computer program stored in a computer readable media, said computer programming having a plurality of code sections that are executable by the at least one machine.

17. A user interface (UI) code generation engine comprising:

a plurality of operating environment code generators configured to generate a set of machine-readable instructions specific to a target operating environment based upon a configuration description document, wherein the configuration description document is written using a standardized meta-language and a declaratively-specified configuration model.

18. The UI engine of claim 17, wherein the configuration description document is written in an extensible markup language (XML) in accordance with a user interface markup language (UIML).

19. The UI engine of claim 17, wherein the target operating environment is at least one of a Web-based environment, a widget-based environment, and a command-line environment.

20. The UI engine of claim 17, wherein at least one of the code generators generates graphical user interface (GUI) code from the configuration description document, and wherein at least one of the code generators generates voice user interface (VUI) code form the configuration description document.
