Abstract

A system, method, and computer program product are provided for altering a line of code. In use, a line of code is identified, where the line of code is written utilizing both a programming language and one or more syntax extensions to the programming language. Additionally, the line of code is altered so that the altered line of code is written using only the programming language. Further, the altered line of code is returned.

Claims

1. A method, comprising:

identifying a line of code, by a processor, wherein the line of code is one of a plurality of lines of code within a source file written utilizing both a programming language and one or more syntax extensions to the programming language;

determining, by a processor, that a first operator in the line of code associated with a first syntax extension of the one or more syntax extensions conflicts with a second operator associated with the programming language, wherein the first operator is specific to a hardware description language;

altering the line of code, by the processor, so that the altered line of code is written using a third operator that does not conflict with the second operator;

speculatively converting a fourth operator in a second line of code to a block of code configured to dynamically check if an operand associated with the fourth operator is part of an aFlow class; and

returning the altered line of code.

2. The method of claim 1, wherein the programming language includes a scripting language.

3. The method of claim 1, wherein the one or more syntax extensions to the programming language include syntax associated with the hardware description language that is not used in or supported by the programming language.

4. The method of claim 1, wherein the one or more syntax extensions include syntax that is recognized and used within the hardware description language and is not recognized by a parser of the programming language.

5. The method of claim 1, wherein the line of code may be altered utilizing an operator table that includes a precedence and an associativity associated with each operator in the table.

6. The method of claim 1, wherein altering the line of code includes changing a syntax extension operator in the line of code to a method call supported by the programming language.

7. The method of claim 6, wherein the method call is an object class method call, where the object class represents a group of signals including implicit flow control signals configured to operate according to an interface protocol.

8. The method of claim 1, wherein altering the line of code includes changing a hardware description language statement in the line of code that is not supported by the programming language to a method call supported by the programming language.

9. The method of claim 1, further comprising calling into a method to handle the fourth operator when the operand associated with the fourth operator is part of the aFlow class.

10. The method of claim 1, further comprising performing an operation corresponding to the fourth operator according to the programming language when the operand associated with the fourth operator is not part of the aFlow class.

11. The method of claim 1, further comprising:

recording each line of the source file; and

attaching an associated node in a source database with each recorded line of the source file.

12. A computer program product embodied on a computer readable medium, comprising:

code for identifying a line of code, wherein the line of code is one of a plurality of lines of code within a source file written utilizing both a programming language and one or more syntax extensions to the programming language;

code for determining that a first operator in the line of code associated with a first syntax extension of the one or more syntax extensions conflicts with a second operator associated with the programming language, wherein the first operator is specific to a hardware description language;

code for altering the line of code so that the altered line of code is written using a third operator that does not conflict with the second operator;

speculatively converting a fourth operator in a second line of code to a block of code configured to dynamically check if an operand associated with the fourth operator is part of an aFlow class; and

code for returning the altered line of code.

13. The computer program product of claim 12, further comprising calling into a method to handle the fourth operator when the operand associated with the fourth operator is part of the aFlow class.

14. The computer program product of claim 12, further comprising performing an operation corresponding to the fourth operator according to the programming language when the operand associated with the fourth operator is not part of the aFlow class.

15. The computer program product of claim 12, further comprising:

recording each line of the source file; and

attaching an associated node in a source database with each recorded line of the source file.

16. A system, comprising:

a processor for;

identifying a line of code, wherein the line of code is one of a plurality of lines of code within a source file written utilizing both a programming language and one or more syntax extensions to the programming language;

determining that a first operator in the line of code associated with a first syntax extension of the one or more syntax extensions conflicts with a second operator associated with the programming language, wherein the first operator is specific to a hardware description language;

altering the line of code so that the altered line of code is written using a third operator that does not conflict with the second operator;

speculatively converting a fourth operator in a second line of code to a block of code configured to dynamically check if an operand associated with the fourth operator is part of an aFlow class; and

returning the altered line of code.

17. The system of claim 16, further comprising calling into a method to handle the fourth operator when the operand associated with the fourth operator is part of the aFlow class.

18. The system of claim 16, further comprising performing an operation corresponding to the fourth operator according to the programming language when the operand associated with the fourth operator is not part of the aFlow class.

19. The system of claim 16, further comprising:

recording each line of the source file; and

attaching an associated node in a source database with each recorded line of the source file.
