Abstract

A code generator tool capable of creating command shell commands at compile time or runtime from a schema such as an XSD schema is provided. The code generator generates classes to represent data defined by a schema and the command shell generation code may use knowledge of the classes to generate appropriate command shell classes to manipulate the data. Plug-ins may be inserted following optimization of a model of classes generated by the code generation tool. The plug-ins can modify the model, insert their own code, or disable code generation and generate their own code from the model.

Claims

1. A method executed at least in part in a computing device to generate automatic command shell command code based on a schema, the method comprising:

receiving the schema that includes one or more of;

element declarations, attribute declarations, simple type definitions and complex type definitions;

reading the schema to create a model for classes that include an interface and a structure, wherein the classes validate constraints in the schema;

optimizing the model to translate the schema to an application programming interface (API); and

inserting a plug-in to the optimized model to generate a command for a command shell based on the optimized model by;

disabling generation of a default code for the command, using the plug-in; and

generating a plug-in code for the command, using the plug-in, wherein the command manipulates data that is structured based on the classes according to a class definition in a data store associated with the schema defined by the optimized model at runtime.

2. The method of claim 1, further comprising:

parsing the schema.

3. The method of claim 2, wherein the model includes at least one from a set of:

a class name, a property, and a data type associated with the classes.

4. The method of claim 3, wherein the model further includes information associated with at least one of:

choices and enumerations.

5. The method of claim 4, wherein the choices are handled by implementing the interface.

6. The method of claim 1, wherein the command is a cmdlet for the command shell.

7. The method of claim 1, wherein the plug-in modifies the model and inserts the plug-in code into the classes.

8. The method of claim 1, wherein the plug-in employs an object model exposed by a class generator to provide information about generated classes and interfaces.

9. The method of claim 8, wherein the class generator is product independent, and the plug-in is product dependent.

10. The method of claim 8, wherein the plug-in generates a command shell cmdlet without parsing the schema.

11. A computing device to generate automatic command shell command code based on a schema, the computing device comprising:

a memory,

a processor coupled to the memory, wherein the processor executes a code generator tool configured to;

receive the schema that includes one or more of;

element declarations, attribute declarations, simple type definitions and complex type definitions, and the schema components belonging to a target namespace;

read the schema to create a model for classes that include an inters and a structure, wherein the classes validate constraints in the schema;

optimize the model to translate the schema to an application programming interface (API); and

insert a plug-in to the optimized model to generate a command for a command shell based on the optimized model, wherein the plug-in is configured to;

disable generation of a default code for the command; and

generate a plug-in code for the command, wherein the command manipulates data that is structured based on the classes defined by the optimized model at runtime.

12. The computing, device of claim 11, wherein the schema is an XSD schema.

13. The computing, device of claim 11, wherein the code generator tool is further configured to generate classes based on the model, and the classes provide one of a serialization and a deserialization using an Xelement.

14. The computing device of claim 13, wherein the Xelement is automatically updated in response to an update to at least one property in a corresponding class.

15. A computer-readable memory device with instructions stored thereon to generate automatic command shell cmdlet code based on a schema, the instructions comprising:

receiving the schema that includes one or more of;

element declarations, attribute declarations, simple type definitions and complex type definitions, the schema components belonging to a target namespace;

reading the schema to create a model for classes, wherein the classes validate constraints within the schema;

optimizing the model to translate the schema to an application programming interface (API); and

inserting a plug-in to the model to generate a cmdlet for a command shell based on the optimized model by;

disabling generation of a default code for the cmdlet, using the plug-in; and

generating a plug-in code for the cmdlet, using the plug-in, wherein the cmdlet manipulates data that is structured based on the classes defined by the optimized model at runtime.

16. The computer-readable memory device of claim 15, wherein the instructions further comprise:

manipulating the data through the API.

17. The computer-readable memory device of claim 15, wherein the instructions further comprise:

one of;

serializing and deserializing using an Xelement that is automatically updated in response to an update to at least one property in a corresponding class.
