Abstract

Source languages are translated to target dynamic programming languages. Runtime functionality including reflection and/or dynamic code modification exposed by a source language is mapped to a dynamic language implementation such as that of a script language. Target language dynamism is leveraged to efficiently support runtime functionality in a source language that is more static, for example.

Claims

1. A runtime code system, comprising:

an interface component that acquires static code that specifies runtime functionality; and

a translation component that translates the static code to dynamic code for execution in a dynamic runtime environment.

2. The system of claim 1, further comprising a map component that maps the structured static code to unstructured dynamic language constructs.

3. The system of claim 2, the dynamic language constructs include prototypes and/or evaluation operations.

4. The system of claim 1, at least one of the interface and translation components form part of a runtime environment component.

5. The system of claim 4, the runtime environment component includes a subset of functionality available statically.

6. The system of claim 1, at least one of the interface and translation components form part of a web service employable by the dynamic runtime environment.

7. The system of claim 1, the dynamic code includes at least a portion of static code to be translated at runtime.

8. The system of claim 1, further comprising a load component that provides static code from outside a dynamic language program to be translated at runtime.

9. The system of claim 1, the static code is intermediate language code common to one or more program languages.

10. The system of claim 1, the dynamic code is script code.

11. A method of computer program execution, comprising:

dynamically translating statically typed language code to dynamically typed language code; and

interpreting the dynamically typed code.

12. The method of claim 11, further comprising generating dynamically typed language code at runtime.

13. The method of claim 11, further comprising loading dynamically typed code from an external source at runtime.

14. The method of claim 11, further comprising transforming a statically typed object to a dynamically typed object.

15. The method of claim 11, further comprising adding a class, class member or instance thereof.

16. The method of claim 11, further comprising deleting a class, class member or instance thereof.

17. A system for supporting runtime code modification, comprising:

means for identifying statically typed language code to be injected into a script during execution thereof; and

means for translating the statically typed language code to script language code at runtime.

18. The system of claim 17, further comprising a means for generating the statically typed language code at runtime.

19. The system of claim 17, further comprising means for loading the statically typed language code from a source outside the script.

20. The system of claim 17, further comprising a means for translating statically typed language code to script code at compile time.
