Abstract

A method of generating language specific code comprising the steps of extracting neutral code from a knowledge base, preprocessing the neutral code, providing a code generator with the preprocessed neutral code and a target language in to which the preprocessed neutral code is to be translated, and processing the preprocessed neutral code by translating the neutral code into a target language code.

Claims

1. A method of generating language specific code comprising the steps of:

receiving a request from a knowledge base to generate target language code from neutral code stored in said knowledge base;

extracting said neutral code from said knowledge base;

preprocessing said neutral code;

providing a code generator with said preprocessed neutral code and a target language in to which said preprocessed neutral code is to be translated; and

processing said preprocessed neutral code by translating said neutral code into said target language code.

2. The method of claim 1 wherein the code generator comprises:

a generator comprising the logical rules which form said target language, and a tech blade component comprising the syntax of said target language.

3. The method of claim 1 wherein processing said preprocessed neutral code comprises the step of invoking a code generator to translate said neutral code into target language code.

4. The method of claim 1 wherein translating said neutral code into target language code comprises the steps of:

requesting syntactic information from a tech blade; and

combining the structure of said neutral code with said syntactic information.

5. The method of claim 1 wherein the preprocessing of said neutral code comprises the step of removing space characters from variable names.

6. The method of claim 1 wherein the preprocessing of said neutral code comprises the step of resolving variable scope conflicts.

7. The method of claim 1 wherein the preprocessing of said neutral code comprises the step of interactively alerting a user of possible undefined or misdefined variables.

8. The method of claim 1 wherein the code generator is stored as a dynamic link library (DLL).

9. A method of generating language specific code comprising the steps of:

receiving a request from a knowledge base to generate target language code from neutral code stored in said knowledge base;

extracting said neutral code from said knowledge base;

providing a code generator with said neutral code and a target language in to which said neutral code is to be translated; and

processing said neutral code by translating said neutral code into said target language code.

10. The method of claim 9 wherein the code generator comprises:

a generator comprising the logical rules which form said target language, and

a tech blade component comprising the syntax of said target language.

11. The method of claim 9 wherein processing said neutral code comprises the step of invoking a code generator to translate said neutral code into target language code.

12. The method of claim 9 wherein translating said neutral code into target language code comprises the steps of:

requesting syntactic information from a tech blade; and

combining the structure of said neutral code with said syntactic information.

13. The method of claim 9 further comprising preprocessing said neutral code.

14. The method of claim 13 wherein the preprocessing of said neutral code comprises the step of removing space characters from variable names.

15. The method of claim 13 wherein the preprocessing of said neutral code comprises the step of resolving variable scope conflicts.

16. The method of claim 13 wherein the preprocessing of said neutral code comprises the step of interactively alerting a user of possible undefined or misdefined variables.

17. The method of claim 9 wherein the code generator is stored as a dynamic link library (DLL).
