# Add .gitignore-Aware File Filtering to gemini-cli
This pull request introduces .gitignore-based file filtering to the gemini-cli, ensuring that git-ignored files are automatically excluded from file-related operations and suggestions throughout the CLI. The update enhances usability, reduces noise from build artifacts and dependencies, and provides new configuration options for fine-tuning file discovery.
Key Improvements
.gitignore File Filtering
All @ (at) commands, file completions, and core discovery tools now honor .gitignore patterns by default.
Git-ignored files (such as node_modules/, dist/, .env, and .git) are excluded from results unless explicitly overridden.
The behavior can be customized via a new fileFiltering section in settings.json, including options for:
Turning .gitignore respect on/off.
Adding custom ignore patterns.
Allowing or excluding build artifacts.
Configuration & Documentation Updates
settings.json schema extended with fileFiltering options.
Documentation updated to explain new filtering controls and usage patterns.
Testing
New and updated integration/unit tests for file filtering logic, configuration merging, and edge cases.
Test coverage ensures .gitignore filtering works as intended across different workflows.
Internal Refactoring
Core file discovery logic refactored for maintainability and extensibility.
Underlying tools (ls, glob, read-many-files) now support git-aware filtering out of the box.

This change detects the most recent git commit short hash and writes it to the `GIT_COMMIT_INFO` constant in `packages/cli/src/generated/git-commit.sh`, optionally appending the string "(local modifications)" if additional local changes after that commit are detected.
If set, this string is displayed in the `/about` dialog as well as passed into the `/bug` template.
Example:

Additionally, this change updates `.gitignore` to ignore the generated files, `scripts/clean.sh` to remove them, and adds a `npm run generate` stage for this and any other generators we need to write.
Increases the threshold for rendering diff separators in the CLI's diff display. Previously, a separator was shown for gaps of more than one context line, leading to excessive separators in diffs with many small changes close together (Issue #534).
By increasing `MAX_CONTEXT_LINES_WITHOUT_GAP` to 5, we allow for more context lines before a separator is added, significantly reducing visual clutter in such diffs.
Added a test case to `DiffRenderer.test.tsx` to verify that separators are not rendered for small gaps within the new threshold.
No intentional different behavior aside for tweaks suggested from the code review of #506 Refactor: Extract console message logic to custom hook
This commit refactors the console message handling from App.tsx into a new custom hook useConsoleMessages.
This change improves the testability of the console message logic and declutters the main App component.
Created useConsoleMessages.ts to encapsulate console message state and update logic.
Updated App.tsx to utilize the new useConsoleMessages hook.
Added unit tests for useConsoleMessages.ts to ensure its functionality.
I deleted and started over on LoadingIndicator.test.tsx as I spent way too much time trying to fix it before just regenerating the tests as the code was easier to write tests for from scratch and the existing tests were not that good (I added them in the previous pull request).
Adds the following conventional readline-like keybindings:
- `Ctrl+H`: Delete the previous character.
- `Ctrl+D`: Delete the next character.
Additionally, remaps the Debug Console command from Ctrl+D to Ctrl+O, which had been first introduced in PR #486.
