The use and application of go clean in Go language

The go clean command of the Go language is used to clean the files generated during the build process and keep the project directory clean. Options include: -i: Clear unused and exported documents. -r: Recursively clean the project and its dependencies. The command go clean -r removes build intermediate files and test binaries such as the _build/ and _test/ directories. Use the -i option with caution as it deletes unused and exported documents.

go clean in Go language: a practical guide

Introduction

go clean is a command in the Go language, used to clean files generated during the build process. It clears module caches, build intermediate files, and test binaries to keep your project directory tidy.

Syntax

go clean [-i] [-r] [(packages)]

Options

• -i: Clear all documents including Unused and unexported content.
• -r: Recursively clean the project and its dependencies.

Practical case

Assume that there are the following files in the project directory:

• main.go: Contains the main code of the application.
• package.go: Contains additional packages and features.
• _build/: Contains module cache and build intermediate files.
• _test/: Contains test binaries.

To clean the build artifacts of the entire project, you can run the following command:

go clean -r

This command will delete the directories _build/ and _test/ and all other intermediate build files. If desired, unused and exported documents can also be deleted using the -i option.

Note

• go clean will not delete compiled binaries in the bin/ directory.
• For large projects, using the -r option may take longer.
• Be careful when cleaning files that are not related to the build process (such as third-party libraries or other projects).

Conclusion

go clean is a useful command that can be used to keep the Go language project directory clean and clear unnecessary Build artifacts to simplify code management and maintenance.
