# Rename a symbol across the repo in Godot with Atlas in 2026

> Atlas renames symbols across your Godot project by combining `lsp` for authoritative references, `grep` for non-code occurrences, and `edit` for precise, safe replacements.

To rename a function, class, or constant everywhere it is used in a Godot project, including references that `grep` alone might miss or wrongly match, Atlas leverages its `lsp`, `grep`, and `edit` tools. This ensures a comprehensive and type-aware refactoring process across your GDScript files, node paths, and signals, providing a practical option for maintaining code integrity in 2026.

## Key takeaways

- Atlas uses `lsp` for precise, type-aware symbol reference finding in Godot projects.
- The `grep` tool in Atlas catches non-code occurrences of symbols in Godot, like strings and comments.
- Atlas's `edit` tool provides safe, controlled renaming, preventing ambiguous matches in Godot files.
- Integration with `GUT (Godot Unit Test)` and `gdformat (gdtoolkit)` ensures code quality post-refactoring.
- Atlas understands Godot project structure, including `.gd` scripts, node paths, and autoloads.
- Every change is presented as a unified diff for explicit user approval before being applied.

## How Atlas ensures accurate symbol renames in Godot

Atlas ensures accurate symbol renames in Godot by combining language server protocol (LSP) data with keyword search, covering 100% of potential occurrences. This hybrid approach, available in 2026, prevents the common pitfalls of simple find-and-replace operations.

Renaming a symbol in a Godot project can be complex, as references exist not only in GDScript files but also within scene files, node paths, and even comments or documentation. Atlas addresses this by first using the `lsp` tool's `findReferences` operation. This queries the language server to get an authoritative list of all code-level usages of the symbol, ensuring that all type-system-aware references are correctly identified. Following this, Atlas employs its `grep` tool to scan for the old symbol name in places the language server might not cover, such as string literals, comments, documentation, or configuration files like `project.godot`. This two-pronged strategy guarantees that every instance of the symbol, whether it's a function call, a class instantiation, a constant reference, or a string literal, is considered for renaming.

## Performing the rename with Atlas's edit tool

Once all references are identified, Atlas performs the mechanical renaming using its `edit` tool, which offers precise control over replacements. The `edit` tool's `replaceAll` feature handles multiple occurrences within a file, while enforcing uniqueness for single changes, preventing unintended modifications in 2026.

The core of the renaming operation is handled by the Atlas `edit` tool. For cases where a symbol appears multiple times within a single file and all instances need to be updated, `edit` uses its `replaceAll` functionality. This is particularly useful for GDScript files where a function might be called several times. Crucially, the `edit` tool is designed with safety in mind: if a single replacement is intended, `edit` enforces uniqueness. It will throw an error, specifically 'Found multiple matches for oldString', if it detects more than one match for a single-occurrence replacement, unless `replaceAll` is explicitly opted into. This prevents silent corruption of your Godot codebase by ensuring that ambiguous matches are flagged for review, giving you full control over every change.

## Review and validation in your Godot workflow

After Atlas proposes changes, a critical review and validation phase follows, integrating directly with Godot's native toolchain. This includes running `GUT (Godot Unit Test)` and `gdformat (gdtoolkit)` to ensure code quality and correctness, a process that takes less than 5 minutes.

Atlas integrates direct into your existing Godot development workflow for review and validation. Once the `edit` tool has applied the renames, Atlas computes a unified diff for every modified file, presenting it for your approval before any changes are written to disk. This allows you to visually inspect every proposed change. After approval, Atlas can execute your project's build and test commands using its `bash` tool. For Godot projects, this means running `godot --headless -s addons/gut/gut_cmdln.gd` to execute `GUT (Godot Unit Test)` tests, ensuring the refactoring hasn't introduced regressions. Additionally, Atlas can run `gdformat` from `gdtoolkit` over the touched scripts to maintain consistent code style, ensuring your GDScript remains clean and adheres to project standards. A final `grep` for the old symbol name confirms zero remaining hits, providing confidence in the completeness of the rename.

## Setting up Atlas for Godot projects

To begin renaming symbols in your Godot project with Atlas, ensure Atlas is run from the project root containing `project.godot`. Atlas will then automatically index your `.gd` scripts, node paths, and autoload singletons, preparing your codebase for intelligent refactoring in 2026.

Getting Atlas ready for your Godot project is straightforward. You simply need to run `atlas` from the root directory of your Godot project, where the `project.godot` file resides. Atlas is designed to understand the unique structure of Godot projects. It will automatically read and index your `.gd` scripts, parse the node paths accessed via `$` or `get_node`, and recognize autoload singletons defined in your project settings. This deep understanding of the Godot toolchain allows Atlas to perform context-aware operations, such as replacing a fragile `get_node` path with a more robust `@onready var` and an exported `NodePath` if needed, or accurately identifying all references to a symbol across your game's logic and scene structure. This setup ensures that Atlas has a comprehensive view of your codebase, enabling precise and safe refactoring.

## Steps

1. Run `atlas` in your Godot project's root directory, ensuring `project.godot` is present, so Atlas can index your `.gd` scripts, node paths, and autoload singletons.
2. Initiate the rename by asking Atlas to refactor a specific function, class, or constant, for example: "Atlas, rename `old_function_name` to `new_function_name` across the repo."
3. Atlas will use its `lsp` tool to perform `findReferences` on the symbol, gathering all authoritative code-level usages from the Godot language server.
4. Concurrently, Atlas will use its `grep` tool to search for the old symbol name in comments, strings, documentation, and configuration files like `project.godot`.
5. Review the plan drafted by Atlas's read-only plan agent, which outlines the proposed changes, and approve it to proceed to the build agent.
6. Atlas's `edit` tool will then apply the mechanical renames, using `replaceAll` for multiple occurrences within a file and enforcing uniqueness for single changes.
7. Review the unified diff presented by Atlas for every file edit, approving each change before it is written to disk.
8. Execute your Godot project's tests using Atlas's `bash` tool by running `godot --headless -s addons/gut/gut_cmdln.gd` to ensure no regressions were introduced.
9. Instruct Atlas to run `gdformat` from `gdtoolkit` over the touched `.gd` scripts to maintain consistent code style: "Atlas, run `gdformat` on all modified GDScript files."
10. Perform a final verification by using Atlas's `grep` tool to search for the `old_function_name` to confirm zero remaining instances.

## FAQ

### How does Atlas handle renaming symbols in Godot scene files?

Atlas's `lsp` tool identifies references within GDScript, which often includes paths to nodes or resources used in Godot scene files. While `lsp` focuses on code, the subsequent `grep` pass catches string-based references that might appear in `.tscn` or `.tres` files, ensuring comprehensive coverage.

### Can Atlas rename Godot signals or node paths?

Yes, Atlas can rename symbols that are part of Godot signals or node paths. By indexing `.gd` scripts and understanding node paths accessed via `$` or `get_node`, Atlas can identify and propose changes to these references, ensuring consistency across your Godot project.

### What if a symbol name appears in a comment in my GDScript?

Atlas's workflow explicitly includes a `grep` step after `lsp` reference finding. This `grep` pass is designed to catch occurrences of the old symbol name in non-code contexts, such as comments, documentation, or string literals within your GDScript files, allowing you to decide if these should also be updated.

### How does Atlas prevent accidental renames in Godot?

Atlas employs several safety mechanisms. It drafts a read-only plan for your approval, computes a unified diff for every proposed file edit, and requires explicit approval before writing changes. Furthermore, the `edit` tool refuses ambiguous single replacements, throwing an error if multiple matches are found where only one was expected, unless `replaceAll` is specified.

### Does Atlas support Godot's `gdformat` for code style after renaming?

Yes, Atlas integrates with `gdformat (gdtoolkit)`. After performing renames, you can instruct Atlas to run `gdformat` over the modified `.gd` scripts using its `bash` tool, ensuring that your refactored code adheres to your project's formatting standards.

### Can Atlas run `GUT (Godot Unit Test)` to verify renames?

Absolutely. Atlas can execute your Godot project's tests using its `bash` tool. After a rename operation, you can run `godot --headless -s addons/gut/gut_cmdln.gd` through Atlas to automatically verify that the refactoring has not introduced any regressions in your `GUT` test suite.

### Is Atlas aware of Godot's autoload singletons when renaming?

Yes, Atlas is designed to understand Godot's project structure. When run in a project with `project.godot` at its root, Atlas reads and indexes autoload singletons defined in your project settings, ensuring that references to these global scripts are correctly identified and handled during a rename operation.

### What if I need to roll back a rename performed by Atlas in Godot?

Atlas snapshots file changes as git patches. This means that every edit made by Atlas can be easily diffed and rolled back, providing a safety net for any refactoring operations in your Godot project.
