System and method for performing error recovery in an integrated development environment
View Patent ↗A system and method for compiler error recovery, comprising analyzing the syntactic structure of a first program in a first programming language, wherein the first program can be represented by a first set of tokens, detecting a syntax error in the first program, remedying the syntax error by adding at least one token to the first set of tokens according to one of: 1) a prefix definition; and 2) an idiom definition, and wherein the detection of the syntax error occurs at the behest of an extensible compiler framework.
1. A method for code completion compiler error recovery while creating software code in an integrated development environment, comprising:
parsing the syntactic structure of a first program in a first programming language, wherein the first program can be represented by a first set of tokens;
detecting a syntax error in the first program;
correcting the syntax error by adding at least one token to the first set of tokens according to one of: 1) a prefix, wherein a prefix is the combination of an opening delimiter with a newly created closing delimiter, and 2) an idiom, wherein an idiom is a specific insertion sequence that can be used to overcome common errors in a given programming language; and
wherein an extensible compiler framework detects the syntax error.
2. The method of claim 1 , further comprising:
correcting the syntax error by removing at least one token from the first set of tokens according to a grammar rule if the syntax error cannot be corrected by adding at least one token to the set of tokens.
3. The method of claim 2 wherein:
the grammar rule incorporates the syntax error into a grammatical definition of the first programming language.
4. The method of claim 1 wherein:
the prefix includes an opening delimiter and a closing delimiter.
5. The method of claim 1 wherein:
the prefix associates an unmatched delimiter with the at least one token.
6. The method of claim 1 wherein;
the at least one token is an operator if there is no applicable prefix.
7. The method of claim 1 wherein:
the idiom associates a syntax error with the at least one token.
8. The method of claim 1 wherein the step of remedying the syntax error includes:
adding a terminator to the first set of tokens.
9. The method of claim 1 wherein:
the extensible compiler framework can integrate and interact with compilers for different programming languages through a common interface.
10. The method of claim 1 wherein:
the first program in the first programming language can be nested within a second program in a second programming language.
11. The method of claim 1 wherein;
a second program in a second programming language is nested within the first program in the first programming language.
12. A method for code completion compiler error recovery while creating software code in an integrated development environment, comprising:
parsing the syntactic structure of a first program in a first programming language, wherein the first program can be represented by a first set of tokens;
detecting a syntax error in the first program;
correcting the syntax error by adding at least one token to the first set of tokens according to one of: 1) a prefix, wherein a prefix is the combination of an opening delimiter with a newly created dosing delimiter; and 2) an idiom definition, wherein an idiom is a specific insertion sequence that can be used to overcome common errors in a given programming language; and
wherein an extensible compiler framework detects the syntax error; and
wherein the extensible compiler framework can integrate and interact with compilers for different programming languages through a common interface.
13. The method of claim 12 , further comprising:
correcting the syntax error by removing at least one token from the first set of tokens according to a grammar rule if the syntax error cannot be remedied by adding at least one token to the set of tokens.
14. The method of claim 13 wherein:
the grammar rule incorporates the syntax error into a grammatical definition of the first programming language.
15. The method of claim 12 wherein:
the prefix includes an opening delimiter and a closing delimiter.
16. The method of claim 12 wherein:
the prefix associates an unmatched delimiter with the at least one token.
17. The method of claim 12 wherein:
the at least one token is an operator if there is no applicable prefix.
18. The method of claim 12 wherein:
the idiom associates a syntax error with the at least one token.
19. The method of claim 12 wherein the step of remedying the syntax error includes:
adding a terminator to the first set of tokens.
20. The method of claim 12 wherein:
the first program in the first programming language can be nested within a second program in a second programming language.
21. The method of claim 12 wherein:
a second program in a second programming language is nested within the first program in the first programming language.
22. A machine readable storage medium having instructions stored thereon that when executed by a processor cause a integrated development environment code completion system to:
parse the syntactic structure of a first program in a first programming language, wherein the first program can be represented by a first set of tokens;
detect a syntax error in the first program;
correct the syntax error by adding at least one token to the first set of tokens according to one of: 1) a prefix, wherein a prefix is the combination of an opening delimiter with a newly created closing delimiter; and 2) an idiom, wherein an idiom is a specific insertion sequence that can be used to overcome common errors in a given programming language; and
wherein an extensible compiler framework detects the syntax error.
23. The machine readable storage medium of claim 22 , further comprising instructions that when executed cause the system to:
correct the syntax error by removing at least one token from the first set of tokens according to a grammar rule if the syntax error cannot be remedied by adding at least one token to the set of tokens.
24. The machine readable storage medium of claim 23 wherein:
the grammar rule incorporates the syntax error into a grammatical definition of the first programming language.
25. The machine readable storage medium of claim 22 wherein:
the prefix includes an opening delimiter and a closing delimiter.
26. The machine readable storage medium of claim 22 wherein:
the prefix associates an unmatched delimiter with the at least one token.
27. The machine readable storage medium of claim 22 wherein:
the at least one token is an operator if there is no applicable prefix.
28. The machine readable storage medium of claim 22 wherein:
the idiom associates a syntax error with the at least one token.
29. The machine readable storage medium of claim 22 , further comprising instructions that when executed cause the system to:
add a terminator to the first set of tokens.
30. The machine readable storage medium of claim 22 wherein:
the extensible compiler framework can integrate and interact with compilers for different programming languages through a common interface.
31. The machine readable storage medium of claim 22 wherein:
the first program in the first programming language can be nested within a second program in a second programming language.
32. The machine readable storage medium of claim 22 wherein:
a second program in a second programming language is nested within the first program in the first programming language.
