Solving the fileMatch Pattern Issue for JSON Validation in VS Code Extensions

When developing an extension for Visual Studio Code (VS Code), you may encounter challenges in specifying the correct patterns for JSON validation. One common question developers face is how to ensure that all files ending with .xyz utilize a specific JSON schema. In this guide, we will tackle this issue and provide you with a clear and effective solution.

The Problem

While trying to specify a JSON schema for .xyz files in your VS Code extension, you may have experimented with various fileMatch patterns without success. The relevant portion of your package.json might look something like this:

This configuration might not yield the desired results, leading to confusion about the correct fileMatch options.

The Solution

After consulting with colleagues and testing different configurations, a solution was found that works perfectly for specifying overlay JSON schema for .xyz files. Below are the simplified steps that lead to a successful implementation.

Effective fileMatch Patterns

To accurately set your fileMatch for .xyz files, you need to utilize the following patterns in your package.json:

Explanation of the Patterns

/*.xyz:

This pattern matches any file whose name ends with .xyz, regardless of its directory.

The leading slash signifies that the pattern should start from the root of the workspace.

*.xyz:

Similar to the previous pattern, this one ensures that any file ending with .xyz is matched, irrespective of the folder it resides in.

Summary of Changes

The following adjustments were made to achieve the expected functionality:

Only the patterns /*.xyz and *.xyz were retained in the configuration.

Each pattern was paired with the URL to the relevant JSON schema, ensuring that VS Code knows where to look for validation rules.

Conclusion

By following this structured approach, you ensure that your VS Code extension correctly recognizes and validates files ending with .xyz using the specified JSON schema. Adopting the proper fileMatch patterns is vital in enhancing the user's experience and functionality of your extension.

Now that you've got the right fileMatch configuration, dive into building and refining your extension with confidence! Happy coding!
