The Current State of LSP Rename

Oct 13, 2025 by wbrum.org 144 views

Introduction

As developers, we often find ourselves working with large codebases, where renaming a single symbol can have a ripple effect throughout the entire project. The Language Server Protocol (LSP) has made it easier to rename symbols across multiple files, but it can still be a manual process. In this article, we will explore the possibility of automatically renaming symbols globally with LSP, and discuss potential solutions for efficiently testing this feature.

The Current State of LSP Rename

The LSP provides a powerful rename feature that allows us to rename symbols across multiple files. However, this feature is typically triggered manually, either by right-clicking on the symbol and selecting "Rename" or by using a keyboard shortcut. While this is a significant improvement over the old days of manual renaming, it can still be a time-consuming process, especially in large codebases.

The Need for Automation

Automating the rename process would save us a significant amount of time and effort. Imagine being able to rename a symbol with just a few keystrokes, without having to manually trigger the rename action. This would be especially useful in situations where we need to rename a symbol that is used across multiple files, or when we need to rename a symbol that has multiple references.

Enabling Automatic Rename with LSP

So, how can we enable automatic rename with LSP? One possible solution is to leverage the LSP's rename capability and trigger it automatically whenever we change a symbol. This would require us to write a custom plugin or extension that listens for changes to the code and triggers the rename action whenever a symbol is edited.

Testing the LSP Rename Capability

However, there is a catch. How do we efficiently test if the LSP is able to rename the just-edited symbol? This is where Tree-sitter comes in. Tree-sitter is a parser generator tool that can be used to parse code and identify symbols. We could use Tree-sitter to parse the code and identify the symbol that was just edited, and then use this information to trigger the LSP rename action.

Potential Solutions

There are several potential solutions to this problem. One possible solution is to use a custom plugin or extension that listens for changes to the code and triggers the LSP rename action whenever a symbol is edited. Another possible solution is to use a tool like Tree-sitter to parse the code and identify the symbol that was just edited, and then use this information to trigger the LSP rename action.

Implementation Details

So, how would we implement this feature? Here are some possible implementation details:

Custom Plugin or Extension: We could write a custom plugin or extension that listens for changes to the code and triggers the LSP rename action whenever a symbol is edited. This would require us to write code that interacts with the LSP and the code editor.
Tree-sitter Integration: We could use Tree-sitter to parse the code and identify the symbol that was just edited. This would require us to write code that interacts with Tree-sitter and the LSP.
Confirmation Prompt: We could add a confirmation prompt that asks the user if they want to apply the LSP rename action. This would require us to write code that interacts with the code editor and the LSP.

Benefits and Drawbacks

So, what are the benefits and drawbacks of this feature? Here are some possible benefits and drawbacks:

Benefits:

Saves time and effort by automating the rename process
Reduces the risk of errors by ensuring that the rename action is triggered correctly
Improves productivity by allowing developers to focus on other tasks

Drawbacks:

Requires custom plugin or extension development
May require additional configuration or setup
May have performance implications due to the additional processing required

Conclusion

In conclusion, enabling automatic rename with LSP would be a significant improvement over the current manual process. While there are potential solutions to this problem, such as using a custom plugin or extension or integrating with Tree-sitter, there are also potential drawbacks to consider. Ultimately, the decision to implement this feature would depend on the specific needs and requirements of the project.

Future Work

There are several potential areas for future work on this feature. Some possible areas for future work include:

Improving the Custom Plugin or Extension: We could improve the custom plugin or extension by adding additional features or functionality.
Integrating with Other Tools: We could integrate this feature with other tools, such as code formatters or code analyzers.
Improving Performance: We could improve the performance of this feature by optimizing the code or using more efficient algorithms.
