Javascript debugging using just my code
The present invention extends to methods, systems, and computer program products for stepping through JavaScript code in a debugger without landing on errors in library or open source code. A debugger receives user inputs designating one or more segments of the JavaScript code as library code. The debugger then performs debugging operations on the JavaScript code. The debugging operations including a stepping operation for stepping through the JavaScript code to identify errors only in user-generated segments of the JavaScript code, wherein the user-generated segments correspond to code that was not designated as library code.
1. A computer system, comprising:
a processor; and
a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution by the processor, cause the computer system to:
step through a scripting language code document compiled from a plurality of source documents, wherein at least one source document comprises user-generated code and at least one different source document comprises library code only, to identify whether errors are present in the scripting language code document;
determine that an identified error was generated by a library code segment based on determining that particular code that generated the error is from the at least one different source document comprising the library code only;
based on determining the identified error was generated by the library code segment, scan an execution stack to identify a most recently executed user-generated code segment, wherein scanning the execution stack comprises locating a document boundary within the scripting language code document by identifying annotations within the scripting language code document that indicate a beginning and an end of at least one portion of the at least one source document comprising the user-generated code; and
identify, based upon the located document boundary, that a code statement provided after the located document boundary is user-generated code and presenting the code statement on a debugger user interface.
2. The computer system of claim 1 , wherein the document boundary is a code-level comment included in the scripting language code document.
3. The computer system of claim 1 , wherein an evaluation is performed to determine whether a user is interested in reviewing errors in the at least one different source document comprising the library code only.
4. The computer system of claim 1 , wherein user-generated code segments and library code segments are associated with separate documents identified by a source map.
5. The computer system of claim 1 , wherein a relationship between the debugger user interface and a script engine debugger is mediated by a process debug manager.
6. The computer system of claim 5 , wherein the process debug manager translates user inputs into a step behavior of the script engine debugger.
7. The computer system of claim 5 , wherein the process debug manager instructs the script engine when to run.
8. The computer system of claim 7 , wherein the process debug manager instructing the script engine when to run is transparent to a user.
9. The computer system of claim 5 , wherein the process debug manager instructs the script engine to step out of a function call.
10. A method for debugging code in a computer system, the method comprising:
stepping through a scripting language code document compiled from a plurality of source documents, wherein at least one source document comprises user-generated code and at least one different source document comprises library code only, to identify whether errors are present in the scripting language code document;
determining that an identified error was generated by a library code segment based on determining that particular code that generated the error is from the at least one different source document comprising the library code only;
based on determining the identified error was generated by the library code segment, scanning an execution stack to identify a most recently executed user-generated code segment, wherein scanning the execution stack comprises locating a document boundary within the scripting language code document by identifying annotations within the scripting language code document that indicate a beginning and an end of at least one portion of the at least one source document comprising the user-generated code; and
identifying, based upon the located document boundary, that a code statement provided after the located document boundary is user-generated code and presenting the code statement on a debugger user interface.
11. The method of claim 10 , wherein the document boundary is a code-level comment included in the scripting language code document.
12. The method of claim 10 , wherein an evaluation is performed to determine whether a user is interested in reviewing errors in the at least one different source document comprising the library code only.
13. The method of claim 10 , wherein user-generated code segments and library code segments are associated with separate documents identified by a source map.
14. The method of claim 10 , wherein the annotations indicate when a script is going to transition between documents.
15. One or more hardware storage devices having stored thereon computer-executable instructions that are executable by one or more processor(s) of a computing system to cause the computing system to at least:
step through a scripting language code document compiled from a plurality of source documents, wherein at least one source document comprises user-generated code and at least one different source document comprises library code only, to identify whether errors are present in the scripting language code document;
determine that an identified error was generated by a library code segment based on determining that particular code that generated the error is from the at least one different source document comprising the library code only;
based on determining the identified error was generated by the library code segment, scan an execution stack to identify a most recently executed user-generated code segment, wherein scanning the execution stack comprises locating a document boundary within the scripting language code document by identifying annotations within the scripting language code document that indicate a beginning and an end of at least one portion of the at least one source document comprising the user-generated code; and
identify, based upon the located document boundary, that a code statement provided after the located document boundary is user-generated code and presenting the code statement on a debugger user interface.
16. The one or more hardware storage devices of claim 15 , wherein the document boundary is a code-level comment included in the scripting language code document.
17. The one or more hardware storage devices of claim 15 , wherein an evaluation is performed to determine whether a user is interested in reviewing errors in the at least one different source document comprising the library code only.
18. The one or more hardware storage devices of claim 15 , wherein user-generated code segments and library code segments are associated with separate documents identified by a source map.
19. The one or more hardware storage devices of claim 18 , wherein the source map identifies document boundaries and content.
20. The one or more hardware storage devices of claim 18 , wherein a relationship between the debugger user interface and a script engine debugger is mediated by a process debug manager.
