Question 1

How do I use go-bind-plugin with go generate?

Accepted Answer

Add a //go:generate directive in your code with flags like -plugin-package and -output-path. The README provides an example that rebuilds the plugin and generates wrappers automatically on each run.

Question 2

go-bind-plugin vs manual plugin loading: which is better?

Accepted Answer

go-bind-plugin is better for type safety and reducing boilerplate, especially with multiple symbols. Manual loading might suffice for trivial cases, but go-bind-plugin automates validation and integrity checks, as highlighted in the README's comparison.

Question 3

Can go-bind-plugin handle plugins on Windows or macOS?

Accepted Answer

No, because Go plugins are not supported on Windows and have limited support on macOS. go-bind-plugin relies on the native plugin system, so it's effectively Linux-only for production use.

Question 4

How to mock a plugin for testing with go-bind-plugin?

Accepted Answer

Use the -interface flag to generate an interface instead of a struct. Then, create mock implementations that satisfy the interface, allowing easy unit testing without loading the actual plugin.

Question 5

What happens if the plugin symbols change after generation?

Accepted Answer

The generated wrapper will have type mismatches, causing errors at load time. You must regenerate the wrapper using go-bind-plugin whenever the plugin interface is updated, which adds maintenance overhead.

Question 6

Does go-bind-plugin support plugins with struct methods or nested types?

Accepted Answer

It can handle exported functions and variables, but complex types like struct methods might require careful reflection. The README focuses on basic symbols, so edge cases may need manual intervention.
