Can Go Libraries Be Distributed Without Source Code?

Distributing Binary Packages in Go: Addressing the Need for Source-Less Distribution

Go libraries are typically distributed with both source codes and precompiled binary packages (.a files). While this approach ensures compatibility and ease of development, it poses a challenge for those who wish to distribute their libraries without revealing their source code.

A common misconception is that precompiled binary packages alone cannot be used directly. However, this is not the case. The Go compiler relies on the .a files to resolve dependencies and build executable code.

The challenge arises when using the go tool, which is typically employed for building Go projects. The go tool requires the presence of source files, even if they are empty dummy files with timestamps older than the binary packages. This requirement is not mentioned explicitly in the Go documentation, which can lead to confusion.

To address this issue, some have suggested maintaining dummy source files with timestamps that are lower than the timestamps of the binary packages. However, this approach introduces the potential for timestamp updates to occur, leading to compatibility issues.

Considering the conflicting information available, the following questions arise:

• Is distributing Go sources the only viable option?
• Why does Go not provide a provision for using .a files directly?
• If keeping source is mandatory, why is it not clearly communicated in the Go documentation?

The answer lies in the nature of the Go compiler. The compiler itself does not require source files, but the go tool does. This distinction has led to misconceptions about the need for source codes when distributing binary packages.

• Distributing Sources Not Mandatory: With the sole reliance on .a files, users can utilize a Go library without the need for source codes.
• .a File Limitations: The lack of direct support for .a files in the go tool stems from its role as a convenience wrapper that automates the compilation process.
• Incomplete Documentation: The absence of clear guidelines in the Go documentation regarding the use of binary packages is a gap that has led to confusion.

By understanding these nuances, developers can confidently distribute Go libraries without the need for source codes, enabling the sharing of precompiled components without compromising intellectual property rights.
