Source Code Analysis System for Dynamic Function Hint Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As programs grow in size, providing effective hints and validating user input in interactive editing environments becomes increasingly difficult due to the growing list of possible inputs and the need for constant updates, especially in maintaining and validating function calls.
Innovation Solution
The solution involves dynamically analyzing source code to generate usage hints by processing functions into parse trees, identifying arguments, and applying rules-based analysis to provide validation and suggestions for both completed and incomplete function calls, using a parse tree data structure to associate user input with corresponding arguments and analyze preconditions and postconditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the program size increases, then the functionality and features are enhanced, but the complexity of maintaining and updating usage hints and validation lists increases
Solution Approach 1:
The system automatically generates usage hints and validation information by analyzing the source code itself. The code analyzer processes function definitions, parameter lists, and usage patterns to dynamically create hints without manual intervention. This self-service approach eliminates the need for manual maintenance of hint lists while adapting to program changes automatically.
Solution Approach 2:
The system performs preliminary analysis of the source code to extract function signatures, parameter types, and usage patterns before the user needs usage hints. By pre-processing the code structure and storing this information in a searchable format, the system can quickly provide accurate hints without re-analyzing the entire codebase during user interaction.
2Reliability
If the list of possible inputs is constantly updated as additional functions are added, then the accuracy of validation is improved, but the time and effort required for maintenance increases
Solution Approach 1:
The code analyzer automatically updates validation information whenever source code changes are detected. It re-processes the modified functions and generates updated validation lists without requiring manual intervention. This self-updating mechanism maintains validation accuracy while eliminating the time-consuming manual maintenance process.
Solution Approach 2:
The system continuously monitors code changes and provides feedback by automatically regenerating validation information based on updated function definitions. This feedback loop ensures that validation accuracy remains high as the program evolves, while the automated nature of the process eliminates manual maintenance time.
3Measurement precision
If manual maintenance of usage hints is performed, then the accuracy of hints is improved, but the productivity of the development environment decreases
Solution Approach 1:
The system automatically generates and maintains usage hints by analyzing the source code structure, function definitions, and parameter usage patterns. This self-service approach produces accurate hints without requiring manual maintenance, thereby maintaining high hint accuracy while significantly improving development productivity by eliminating the time developers would spend on manual hint maintenance.
Data Source
AI summary
A method of dynamically analyzing source code to generate usage hints for a user performing program editing is disclosed. The functions in a collection of source code being edited by a user are processed so as to generate a parse tree data structure for each function called. The incoming and outgoing arguments in the parse tree are identified. Subsequently, a user editing code calls the function and either completely or incompletely enters the arguments as part of the function called. Input arguments are identified and associated with the corresponding argument in the parse tree for the function. Relevant preconditions and post-conditions of the surrounding nodes corresponding to the current location are analyzed. Usage hints are provided for the completion of the function call. Arguments for a completed function call argument entered by the user are validated. Error messages are delivered in the event of an invalid call.
