Can Go Code Be Loaded Dynamically?
Dynamic code loading enables the runtime extension of programs, enhancing flexibility and maintainability. This article explores the possibility of dynamic code loading in Go, addressing the concerns raised by a developer who seeks to load custom Go packages based on runtime information.
Go's (Lack of) Dynamic Libraries
Go currently lacks support for dynamic libraries, which prevents the implementation of standard DLL-based code loading. Patches have emerged to address this limitation, but their inclusion in Go 1.2 remains uncertain.
Alternative Approaches
Despite the absence of dynamic libraries, there are alternative methods to achieve dynamic code loading in Go:
Considerations
While these alternatives provide workarounds for dynamic code loading, it's essential to consider their limitations:
Conclusion
Go does not currently support dynamic libraries for code loading. However, alternative approaches using separate processes or file change monitoring can be explored to achieve similar functionality, albeit with certain trade-offs. Developers should evaluate these options based on their specific requirements and consider the potential for performance or stability issues.
