Gemini CLI: Ignoring .gitignore In Custom Commands

Are you wrestling with the Gemini CLI and finding that your custom commands aren't playing nicely with your .gitignore file? You're not alone! This article dives deep into a specific quirk where Gemini CLI, particularly when referencing files using the @file/path syntax, seems to always respect .gitignore, even when you've explicitly told it not to. We'll explore the issue, the expected behavior, and offer some insights and potential workarounds.

The Core Problem: Ignoring the Ignore Setting

At the heart of the issue is a hardcoded setting within the Gemini CLI's code. This setting dictates whether or not the tool should pay attention to your .gitignore file when deciding which files to include in your prompts. The problem arises because this setting is, in effect, always set to true for the respectGitIgnore parameter, regardless of what you configure in your settings. This means that any files or directories listed in your .gitignore are automatically excluded from the Gemini CLI's context, even if you've explicitly set respectGitIgnore to false in your configuration. This can lead to frustrating situations where essential files are missing from your prompts, and you're left scratching your head, wondering why.

Diving into the Code

The root of this behavior lies within the pathReader.ts file of the Gemini CLI's core package. Specifically, lines 75 to 78 contain the problematic code:

const filteredFiles = fileService.filterFiles(relativeFiles, {
  respectGitIgnore: true,
  respectGeminiIgnore: true,
});

As you can see, respectGitIgnore is hardcoded to true. This means that the filterFiles function, which is responsible for determining which files to include, will always filter out files that are ignored by .gitignore. This behavior directly contradicts the user's expectation when setting respectGitIgnore to false in their configuration. This oversight can significantly impact the functionality of your custom commands, especially if you need to include files that are intentionally excluded from your Git repository.

Impact on Custom Commands

The primary impact of this behavior is on custom commands that use the @file/path syntax to reference files. When a file or directory is ignored by .gitignore and referenced in this way, Gemini CLI will silently exclude it from the context. This can lead to unexpected results and make it difficult to debug your prompts. For instance, if you have a temporary directory like tmp_collector_data that you've added to .gitignore (a common practice), and you attempt to include files from this directory using a custom command, those files will be omitted, regardless of your respectGitIgnore setting.

Expected Behavior vs. Reality

The expected behavior, according to the documentation and the user's configuration, is that the respectGitIgnore setting should control whether or not .gitignore is respected. When set to false, the Gemini CLI should include all files, regardless of their status in .gitignore. The reality, however, is that .gitignore is always respected, regardless of the configuration. This discrepancy creates a significant usability issue, especially for users who need to include files that are intentionally excluded from version control.

Example Scenario

Consider the following scenario:

  1. Directory Structure: You have a directory structure that includes a tmp_collector_data directory, which contains several JSON files (bin_collections.json, council_info.json, etc.).
  2. .gitignore: Your .gitignore file contains the line tmp_collector_data/, ensuring that this directory and its contents are ignored by Git.
  3. Gemini CLI Configuration: You have a configuration file with respectGitIgnore set to false and enableRecursiveFileSearch set to true.
  4. Custom Command: You create a custom command that uses the @file/path syntax to reference files within tmp_collector_data.

Despite your configuration, the files within tmp_collector_data will be ignored, and you'll see a message like this:

ℹFile '@{tmp_collector_data/council_info.json}' was ignored by .gitignore or .geminiignore and was not included in the prompt.

This behavior is unexpected and can disrupt your workflow, particularly if you rely on these files for your prompts.

Workarounds and Potential Solutions

While the hardcoded respectGitIgnore setting presents a challenge, there are potential workarounds and solutions to consider.

Modifying the Gemini CLI Code (Advanced Users)

For advanced users, one potential solution is to modify the Gemini CLI code directly. You could change the respectGitIgnore value in pathReader.ts or modify the behavior of the filterFiles function. However, this is not recommended unless you are familiar with the codebase and comfortable maintaining a custom version. Also, each time you update the Gemini CLI, your changes will be overwritten, which leads to the need to re-apply these custom changes. This approach also comes with the risk of introducing unintended side effects.

Using Alternative File Referencing Methods

If possible, consider using alternative methods to reference the files. For example, you could:

  1. Move the Files: Move the files you need to include outside of the directories that are ignored by .gitignore. This is a simple workaround but may not be feasible in all situations, especially if the files are dynamically generated or need to reside in a specific location.
  2. Specify Absolute Paths: Instead of using @file/path, try using absolute file paths in your custom commands. This might bypass the file filtering logic entirely, but it's less flexible and can make your configurations less portable.

Ignoring .gitignore (Use with Caution)

If you absolutely need to include files that are ignored by .gitignore, you could temporarily modify your .gitignore file to exclude the relevant files or directories. However, exercise extreme caution with this approach, as it could lead to unintentionally committing sensitive or temporary files to your repository.

Feature Request or Bug Fix Submission

The most effective long-term solution is to submit a feature request or bug fix to the Gemini CLI developers. Explain the issue clearly, provide examples, and emphasize the importance of respecting the respectGitIgnore setting. This will help the developers understand the problem and potentially implement a fix in a future release.

Conclusion: Navigating the Gemini CLI and .gitignore

The behavior of the Gemini CLI with respect to .gitignore and custom commands can be perplexing. The hardcoded respectGitIgnore setting creates a situation where the intended configuration is not honored, leading to unexpected file exclusions. While there are workarounds, the ideal solution involves either modifying the CLI code (for advanced users) or, more preferably, submitting a feature request to the developers. By understanding the issue, exploring potential solutions, and advocating for a fix, you can ensure that your Gemini CLI custom commands work as expected and that your prompts include all the necessary files.

It's important to remember that software development is an iterative process, and issues like these are often addressed through updates and bug fixes. Stay informed about Gemini CLI updates and continue to experiment with different approaches to find the best solution for your needs.
