Can Go Dynamically Load Packages at Runtime?

Dynamically Loading Go Code: Is It Possible?

The query arises as to whether it is feasible to dynamically load a Go package during runtime based on information not available at compile time. This would enable users to extend their programs using custom packages, eliminating the need to manually edit and recompile code.

Current Limitations:

Unfortunately, Go does not currently support dynamic libraries. While patches have been proposed by Elias Naur, they remain under review and are unlikely to be integrated into Go 1.2. Refer to the discussions on Google Groups for further details.

Alternative Approaches:

Despite the lack of native dynamic library support, alternative approaches exist:

1. Separate Processes and RPC: Start plugins in separate processes and communicate with the main application using the net/rpc package. This allows for dynamic plugin management and isolation, preventing plugin errors from crashing the main program.
2. File Watcher and Auto-Compilation: Create a script that monitors for changes in the current directory and automatically executes "go build" followed by restarting the program. This approach provides a lightweight and responsive development environment, similar to hot reloading in other languages.
