PR Type:

Refactoring

---

PR Description:

This PR introduces a significant refactor of the codebase to use Abstract Syntax Trees (ASTs) for making code changes. The main changes include:

• Addition of a comprehensive suite of unit tests for testing the functionality of the AST operations.
• Refactoring of the main.py file to handle different configuration settings and improve the UX.
• Introduction of new classes and methods for handling AST operations, including adding, deleting, and modifying functions, classes, methods, and imports.
• Deletion of some old files that are no longer needed due to the refactor.

PR Main Files Walkthrough:

files:

- `backend/tests/test_file_ops.py`: This is a new file that contains a comprehensive suite of unit tests for testing the functionality of the AST operations. The tests cover a wide range of scenarios, including modifying function, class, and method docstrings, adding and deleting imports, modifying classes and methods, renaming variables, adding functions and methods, and deleting classes and functions. - `backend/main.py`: This file has been significantly refactored to handle different configuration settings and improve the UX. The changes include setting the model, setting the max message tokens, setting the directory in prompt, setting the files in prompt, and saving the prompt. The file also includes new endpoints for getting the model, getting the max message tokens, and getting the files in prompt. - `backend/tests/test_ast_ops.py`: This is a new file that contains unit tests for the AST operations. The tests cover adding, deleting, and modifying functions. - `backend/agent/agent_functions/file_ops.py`: This is a new file that contains classes and methods for handling AST operations. The classes include AddClass, DeleteClass, ModifyClass, AddMethod, DeleteMethod, ModifyMethod, AddFunction, DeleteFunction, ModifyFunction, AddImport, DeleteImport, ModifyImport, and VariableNameChange. - `backend/agent/agent_functions/ast_ops.py`: This is a new file that contains classes and methods for applying AST changes. The classes include ASTChangeApplicator, AddFunction, DeleteFunction, and ModifyFunction. - `backend/agent/instructor_example.py`: This is a new file, but the content is not shown in the diff. - `backend/tests/test_coding_agent.py`: This is a new file, but the content is not shown in the diff. - `backend/agent/agent_prompts.py`: This is a new file, but the content is not shown in the diff. - `backend/test.py`: This is a new file, but the content is not shown in the diff. - `backend/agent/tset.json`: This is a new file, but the content is not shown in the diff.

PR Analysis

• 🎯 Main theme: Refactoring the codebase to use Abstract Syntax Trees (AST) for code modifications

• 📝 PR summary: This PR refactors the existing codebase to use Python's Abstract Syntax Trees (AST) for making code modifications. It introduces new classes for different types of code modifications and a transformer to apply these changes to the AST. It also updates the maximum tokens for the GPT model and adds some new tests.

• 📌 Type of PR: Refactoring

• 🧪 Relevant tests added: Yes

• ⏱️ Estimated effort to review [1-5]: 4, because the PR involves significant changes to the codebase and introduces a new way of handling code modifications. It requires a good understanding of Python's AST module to review.

• 🔒 Security concerns: No security concerns found

  PR Feedback

• 💡 General suggestions: The PR is well-structured and introduces a new way of handling code modifications using Python's AST. It's a good practice to use AST for code modifications as it provides a more robust and safer way to make changes. However, it's important to ensure that all edge cases are handled correctly and that the changes don't introduce any new bugs. It would be beneficial to add more tests to cover all the new functionality introduced in this PR.

• 🤖 Code feedback:

  • relevant file: backend/agent/agent_functions/changes.py suggestion: Consider adding error handling for the case where the ast.parse() function fails due to syntax errors in the input code. This could happen if the input code is not valid Python code. You can use a try-except block to catch the SyntaxError exception that ast.parse() raises in such cases. [important] relevant line: '+ self.ast_tree = ast.parse(source_code)'

  • relevant file: backend/agent/agent_functions/changes.py suggestion: The 'is_conflict' method currently always returns False. Consider implementing a proper conflict detection mechanism to prevent applying conflicting changes to the code. [important] relevant line: '+ def is_conflict(self, change):'

  • relevant file: backend/agent/agent_functions/changes.py suggestion: The 'sort_changes' method currently sorts the changes based on their 'priority' attribute. However, it's not clear how the priority of a change is determined. Consider adding a comment or documentation to explain this. [medium] relevant line: '+ return sorted(changes, key=lambda change: change.priority)'

  • relevant file: backend/agent/agent_functions/changes.py suggestion: The 'create_args' method currently parses a function definition to create the arguments. This could fail if the input string is not a valid function definition. Consider adding error handling for this case. [medium] relevant line: '+ def create_args(self, args_str):'
