Abstract

A system, method and computer-readable medium supports a feature that predicts a selection based on history of use and uses this information to pre-select an item in a list for syntax completion in a source program editor.

Claims

1. A system for predicting a desired element associated with a reference for syntax completion in source code, comprising:

a prediction component in a software design environment that predicts a desired element for syntax completion of a statement in source code from a plurality of elements comprising methods associated with a class of an object oriented programming object associated with a reference comprising the object-oriented programming object, the prediction of the desired element based on information associated with past use of at least one element of the plurality of the elements associated with the reference, wherein the prediction is triggered by receiving the reference followed by a scope operator comprising a period (.) or double colon (;

;

); and

a data store for storing the information associated with the past use of the at least one element associated with the reference.

2. The system of claim 1, wherein the reference comprises an interface.

3. The system of claim 1, wherein the reference comprises a struct.

4. The system of claim 1, wherein the reference comprises a namespace.

5. The system of claim 1, wherein the reference comprises a delegate.

6. The system of claim 1, wherein the reference comprises a type.

7. The system of claim 1, wherein the reference comprises an event.

8. The system of claim 1, wherein the reference comprises an enumeration.

9. The system of claim 1, wherein the reference comprises a class.

10. The system of claim 1, further comprising a compiler for providing a list of valid references in the source code.

11. The system of claim 10, wherein the compiler further provides a list of valid elements associated with at least one of the references in the list of valid references.

12. The system of claim 1, further comprising an editor for displaying and updating source text, wherein the editor accepts a selected element from a list of displayed elements and inserts the selected element into the source text.

13. The system of claim 1, further comprising a language service which dynamically parses the source code statement and triggers a display of a list of elements associated with the reference upon detection of a triggering event.

14. The system of claim 1, wherein the information associated with the past use of the at least one element associated with the reference comprises a table for each reference in the source code, the table comprising cells for a predetermined number of reference elements and a use count cell for each reference element of the predetermined number of reference elements.

15. The system of claim 1, wherein the information associated with the past use of the at least one element associated with the reference comprises a table for each reference in the source code, the table comprising cells for a predetermined number of reference elements and a timestamp cell for storing the time of last use for each reference element of the predetermined number of reference elements.

16. A method for completing syntax in source code, the method comprising:

in response to detecting a triggering event comprising receiving a reference comprising an object-oriented programming object followed by a scope operator comprising a period (.) or double colon (;

;

), when the source code is being created, predicting a desired element for syntax completion associated with the reference based on information associated with past use of at least one of a plurality of elements associated with the reference.

17. The method of claim 16, frirther comprising displaying a list of elements associated with the reference, wherein the predicted element is distinguished from the other displayed elements.

18. The method of claim 17, wherein the predicted element is distinguished from the other displayed elements by highlighting the predicted element.

19. The method of claim 17, frirther comprising receiving a user-selected element from the displayed list of elements.

20. The method of claim 19, frirther comprising incrementing a use counter in the information associated with past use of at least one of the plurality of elements, the use counter associated with the selected element, the selected element associated with the reference.

21. The method of claim 19, frirther comprising entering the selected element into the source code.

22. The method of claim 16, wherein the triggering event comprises entering a predetermined character preceded by a reference.

23. The method of claim 16, wherein predicting the desired element associated with the reference based on information associated with past use of at least on of the plurality of elements associated with the reference comprises determining the most frequently used element of the plurality of elements.

24. The method of claim 16, wherein predicting the desired element associated with the reference based on the history of past use comprises determining the most recently used element of the plurality of elements.

25. The method of claim 16, wherein the predicted element is highlighted.

26. The method of claim 16, further comprising accessing a table comprising the information associated with the past use of at least one of a plurality of elements associated with the reference.

27. The method of claim 16, wherein the reference is validated by comparison with a list of valid references provided by a compiler.

28. The method of claim 17, wherein the list of elements associated with the reference is validated by comparison with a list of valid elements for the reference provided by a compiler.

29. The method of claim 16, wherein the triggering event is detected by a dynamic parser that monitors keystroke input into a source code editor.

30. The method of claim 16, wherein the information associated with past use of the elements associated with the reference can be cleared via a user interface.

31. The method of claim 30, wherein clearing the history of past use comprises setting a use counter associated with at least one element associated with the reference to zero.

32. The method of claim 30, wherein clearing the history of past use comprises clearing a table of elements associated with a reference.

33. The method of claim 16, wherein the reference comprises an interface.

34. The method of claim 16, wherein the reference comprises a struct.

35. The method of claim 16, wherein the reference comprises a namespace.

36. The method of claim 16, wherein the reference comprises an enumeration.

37. The method of claim 16, wherein the reference comprises a delegate.

38. The method of claim 16, wherein the reference comprises a class.

39. The method of claim 16, wherein the reference comprises a type.

40. The method of claim 16, wherein the reference comprises an event.

41. A computer-readable storage medium comprising computer-executable instructions for:

in response to detecting a triggering event comprising receiving a reference comprising an object-oriented programming object followed by a scope operator comprising a period (.) or double colon (;

;

), indicating that an element associated with the reference is to be selected when editing source code, predicting a desired element associated with a reference based on information associated with past use of a plurality of elements associated with the reference;

displaying a list of elements associated with the reference; and

distinguishing the predicted element for the other elements in the displayed list of elements associated with the reference.
