Recommended Approach To Migrate From Run-clang-tidy

Introduction

As a developer, you're likely familiar with the importance of maintaining high-quality code. One of the tools that can help you achieve this is Clang-Tidy, a source code analyzer that detects and fixes various issues in your code. However, if you're experiencing long execution times in your Continuous Integration/Continuous Deployment (CI/CD) process, it may be time to consider migrating to a more efficient solution. In this article, we'll explore the recommended approach to migrate from Run-Clang-Tidy to Clangd-Tidy.

Current Setup

You're currently using the script provided by Clang-Tidy in your pipelines, which looks like this:

run-clang-tidy-18.py -clang-tidy-binary clangd-tidy

This script analyzes the entire project based on the compile_commands.json file. However, you've noticed that this approach has some limitations, particularly when it comes to analyzing header files.

Challenges with Current Approach

When you run the script, you've observed that it skips all header files. This is because Clangd-Tidy doesn't open the headers referenced from the .cpp files, and they're not included in the compile_commands.json file. To overcome this limitation, you've tried adding the headers to the compile_commands.json file using the following command:

compdb -p build/ list > compile_commands.json

However, this approach has its own set of challenges. When you run this command, you get errors like:

Error: In included file: main file cannot be included recursively when building a preamble

This is because the headers are being treated as the "main" file, which they're not.

Recommended Approach

So, what's the recommended approach to migrate from Run-Clang-Tidy to Clangd-Tidy? Here are a few suggestions:

1. Use Clangd-Tidy's Built-in Features

Clangd-Tidy has several built-in features that can help you analyze your code more efficiently. One of these features is the ability to analyze header files without requiring the compile_commands.json file. To take advantage of this feature, you can use the following command:

clangd-tidy -header-analysis

This command will analyze all header files in your project without requiring the compile_commands.json file.

2. Use a Custom Compile Database

Another approach is to create a custom compile database that includes all the necessary information about your project. You can use the compdb tool to create a custom compile database that includes the necessary information about your project. Here's an example of how you can create a custom compile database:

compdb -p build/ list > compile_commands.json

However, to avoid the errors mentioned earlier, you can use the following command:

compdb -p build/ list -header-analysis > compile_commands.json

This command will create a custom compile database that includes the necessary information about your project, including the analysis of header files.

3. Use a Third-Party Tool

If you're experiencing difficulties with the built-in features of Clangd-Tidy or creating a custom compile database, you may want to consider using a third-party tool. One such tool is the clang-tidy tool, which provides a more comprehensive set of features for analyzing code. You can use the following command to run the clang-tidy tool:

clang-tidy -header-analysis

This command will analyze all header files in your project without requiring the compile_commands.json file.

Conclusion

Migrating from Run-Clang-Tidy to Clangd-Tidy can be a challenging task, but with the right approach, you can achieve your goals. In this article, we've explored the recommended approach to migrate from Run-Clang-Tidy to Clangd-Tidy, including using Clangd-Tidy's built-in features, creating a custom compile database, and using a third-party tool. By following these suggestions, you can improve the efficiency of your CI/CD process and maintain high-quality code.

Additional Tips

Here are some additional tips to help you migrate from Run-Clang-Tidy to Clangd-Tidy:

  • Use the latest version of Clangd-Tidy: Make sure you're using the latest version of Clangd-Tidy to take advantage of the latest features and improvements.
  • Configure Clangd-Tidy correctly: Configure Clangd-Tidy correctly to ensure that it's analyzing your code correctly.
  • Use a custom compile database: Create a custom compile database to include all the necessary information about your project.
  • Use a third-party tool: Consider using a third-party tool, such as the clang-tidy tool, to analyze your code.

By following these tips and using the recommended approach, you can successfully migrate from Run-Clang-Tidy to Clangd-Tidy and improve the efficiency of your CI/CD process.

Introduction

In our previous article, we explored the recommended approach to migrate from Run-Clang-Tidy to Clangd-Tidy. However, we understand that you may still have some questions about this process. In this article, we'll address some of the most frequently asked questions (FAQs) about migrating from Run-Clang-Tidy to Clangd-Tidy.

Q: What is the main difference between Run-Clang-Tidy and Clangd-Tidy?

A: The main difference between Run-Clang-Tidy and Clangd-Tidy is that Clangd-Tidy is a more efficient and scalable solution for analyzing code. Clangd-Tidy uses a more advanced algorithm to analyze code, which makes it faster and more accurate than Run-Clang-Tidy.

Q: Why is Clangd-Tidy faster than Run-Clang-Tidy?

A: Clangd-Tidy is faster than Run-Clang-Tidy because it uses a more advanced algorithm to analyze code. This algorithm is designed to take advantage of the latest hardware and software technologies, which makes it faster and more efficient than Run-Clang-Tidy.

Q: How do I configure Clangd-Tidy to analyze my code correctly?

A: To configure Clangd-Tidy to analyze your code correctly, you'll need to create a custom compile database that includes all the necessary information about your project. You can use the compdb tool to create a custom compile database that includes the necessary information about your project.

Q: What are the benefits of using a custom compile database?

A: The benefits of using a custom compile database include:

  • Improved accuracy: A custom compile database ensures that Clangd-Tidy has all the necessary information about your project, which makes it more accurate.
  • Faster analysis: A custom compile database makes it faster for Clangd-Tidy to analyze your code.
  • Better support for header files: A custom compile database ensures that Clangd-Tidy can analyze header files correctly.

Q: Can I use a third-party tool to analyze my code?

A: Yes, you can use a third-party tool to analyze your code. One such tool is the clang-tidy tool, which provides a more comprehensive set of features for analyzing code. You can use the following command to run the clang-tidy tool:
