PR Analysis

• 🎯 Main theme: Adding a feature to rename symbols in files and apply changes to the files
• 📝 PR summary: This PR introduces a new feature to the KCL language server that allows renaming symbols in files. It provides the ability to find all occurrences of a symbol in a set of files and rename them to a new name. The changes are then applied to the files. The PR also includes updates to the tests to cover the new functionality.
• 📌 Type of PR: Enhancement
• 🧪 Relevant tests added: Yes
• ⏱️ Estimated effort to review [1-5]: 4, because the PR introduces a new feature with a significant amount of new code. It requires a good understanding of the existing codebase and the language server protocol to review effectively.

PR Feedback

• 💡 General suggestions: The PR is well-structured and the new feature is implemented in a modular way. The code is readable and follows good coding practices. However, it would be beneficial to add more comments to the new functions to explain their purpose and functionality in more detail. This would make it easier for other developers to understand the code.

• 🤖 Code feedback:

  • relevant file: kclvm/tools/src/LSP/src/rename.rs
    suggestion: Consider handling the case where the file cannot be read in the 'apply_rename_changes' function. Currently, the function uses unwrap which may cause the program to panic if the file cannot be read. Instead, you could return an error to the caller. [important]
