Before making any changes, check the output for function definitions to identify duplicates. Look for error messages indicating function redefinitions in the console.
Quote the Duplicate Function Name
Please quote the exact function name you attempted to create in your last output: [FUNCTION NAME]. Then, compare it with the existing function names in the codebase: [CODEBASE]. Confirm whether this function name already exists, and provide a brief explanation of any conflicts or duplicates found.
Paste the Function Definition
Please provide the definition of the function you are attempting to add: [FUNCTION DEFINITION]. I will analyze this definition for any conflicts with existing functions in the codebase. Additionally, I will identify any potential issues that may arise from duplicating functionality and suggest possible resolutions to avoid conflicts.
Interpret the Function Creation Request
Please interpret the request to create a new function based on the following details: [FUNCTION NAME], [FUNCTION PARAMETERS], and [EXPECTED OUTPUT]. Explain your understanding of the requirements, including any potential areas where misinterpretation could occur. Provide a summary of your interpretation and any questions you may have to ensure clarity before proceeding with the function creation.
Expected vs. Actual Function Behavior
Identify the expected behavior of the new function [FUNCTION NAME] compared to the actual behavior observed. Please provide a detailed comparison that highlights any discrepancies in naming conventions, functionality, and performance. Include specific examples of where the actual behavior deviates from the expected behavior, and suggest potential reasons for these discrepancies. Format your response in a structured table with columns for "Expected Behavior," "Actual Behavior," and "Discrepancy Explanation.
Identify the Naming Conflict Rule
Identify the specific rule or constraint that is violated when attempting to create a duplicate function in your code. Please provide the exact clause from the documentation that addresses function naming conflicts. Additionally, explain the implications of this rule on code organization and maintainability.
Target the specific function definition that is causing the conflict. This will involve renaming or modifying the function to ensure uniqueness.
Rename the Duplicate Function
Identify the function at [FILE] on line [LINE] that is creating a duplicate. Rename this function to [NEW FUNCTION NAME] to prevent any conflicts with existing functions in the codebase. Please provide a brief explanation of why renaming is necessary and ensure that all references to the old function name are updated accordingly.
Modify Function Signature
Please modify the function signature located at [FILE]:[LINE] by changing its parameters to [NEW PARAMETERS] while keeping the function body intact. After making the changes, provide me with a diff of the modifications so I can review them before applying. Ensure that the output clearly highlights the differences in the function signature.
Remove Redundant Function Definition
Identify the function at [FILE] on [LINE] that is a duplicate of an existing function. Please provide a detailed explanation of why this function is redundant, and confirm that it has been removed from the codebase. Additionally, outline any potential conflicts that could arise if this function remains and suggest best practices for avoiding such redundancy in the future.
Check for Function Usage
Identify all instances in the codebase where the function [DUPLICATE FUNCTION NAME] is called. Provide a comprehensive list of these references, and ensure that you suggest the necessary updates to replace each instance with the new function name. Format your output as a table with columns for the original function call, the line number, and the suggested updated function call.
Validate Function Imports
Please validate the function imports for [DUPLICATE FUNCTION NAME]. Check that each import correctly points to the appropriate function definition. If you find any incorrect imports, update them to reflect the new function name and provide a summary of the changes made.
Confirm that the duplicate function issue has been resolved by checking the function definitions and their usages.
Run Function Tests
Please execute the tests for the function [NEW FUNCTION NAME] to verify its behavior and ensure there are no conflicts with existing functions. Provide a detailed report of any errors encountered during the testing process, including the nature of the errors and any relevant context that could assist in troubleshooting.
Show Function Definition Diff
Please provide the function definitions before and after the changes in the following format: [FUNCTION_DEFINITION_BEFORE] and [FUNCTION_DEFINITION_AFTER]. I need you to show me the differences between these two definitions, confirming whether the duplicate function has been removed or renamed. Additionally, summarize any other significant changes made to the function.
Replay the Original Scenario
Recreate the original scenario that resulted in the duplicate function error. Please provide a detailed step-by-step account of the actions taken that led to this issue. After recreating the scenario, confirm whether the error still occurs and verify that the correct function is being called. Include any relevant logs or outputs that demonstrate the resolution of the issue.
Check for Edge Cases
Identify and test edge cases for the function [NEW FUNCTION NAME] to determine potential conflicts with other functions. Please provide a detailed list of these edge cases, including specific scenarios that could lead to conflicts. Additionally, explain how each edge case is handled and suggest any necessary adjustments to ensure all cases are managed correctly.
Confirm Function Usages
Please list all references to the function [NEW FUNCTION NAME] in the codebase. For each reference, confirm that it points to the correct definition and verify that it is functioning properly without any errors. Provide a summary of any discrepancies found, along with recommendations for resolving them.
Create artefacts that help prevent the recurrence of duplicate function creation in the future.
Function Naming Convention Prompt
Please create a system prompt that instructs users to check existing function names for conflicts before creating a new function. If a conflict is detected, provide a suggestion for a unique name that adheres to a consistent naming convention. Ensure the prompt emphasizes the importance of avoiding duplicate function names to maintain code clarity and organization.
Function Definition Check Template
Please create a conversation-starter template for checking function definitions in code. The template should prompt users to verify if a function with the same name already exists before adding a new one. If a duplicate is found, include a section that suggests alternative naming options to avoid conflicts. Format the output as a structured checklist with clear sections for verification and naming alternatives.
Project Spec for Function Uniqueness
Please draft a project specification message regarding function uniqueness in our codebase. The message should clearly state that all function names must be unique and emphasize the importance of checking for existing functions before adding new ones to prevent duplication. Additionally, include guidelines on how to conduct these checks and the consequences of not adhering to this rule. Format the message in a professional tone suitable for team communication.
Function Conflict Self-Check
Implement a self-check mechanism for function creation in the codebase. Before finalizing any new function, verify that its name does not conflict with existing function names. If a conflict is detected, provide a list of three alternative names that adhere to the naming conventions used in the project.
Duplicate Function Prevention Constraint
Please create a constraint for a programming environment that enforces the rule: 'No function may share a name with any existing function.' If a duplicate function name is detected, the process should be halted, and the user should be prompted to enter a new name. Provide a code snippet that demonstrates how to implement this constraint effectively.
Creating a function with a duplicate name will lead to a conflict in the codebase, causing runtime errors. Bolt does not automatically handle these conflicts, so it’s crucial to check for existing functions before adding new ones.
You can check for existing functions by reviewing the function definitions in the codebase or using the search feature in Bolt to find function names. This helps prevent duplication during development.
If you encounter a naming conflict, you should rename the new function to ensure it is unique. Bolt does not automatically resolve these conflicts, so manual intervention is necessary.
Bolt does not have built-in functionality to detect duplicate functions automatically. It’s essential to manually verify function names to avoid conflicts during development.
Best practices for naming functions in Bolt include using descriptive names, ensuring uniqueness, and following a consistent naming convention. This helps maintain clarity and prevents conflicts.
