Oops! 

Meant to say *“Using Lua to develop plugins in Go would NOT be ideal IMO.”*

 WebAssembly comes to mind - see, for example, https://wazero.io/

 A plugin would then be a .wasm binary that can be compiled in any 
 language that supports WebAssembly as target.

 Disclaimer: I have not yet tried this approach.

 Hi All !
 Plug-in package is very interesting, but in case the development under 
 windows it does not work,
 So, any hint to use some option instead will be highly appreciated.

 Thank you.

I recently started using github.com/yuin/gopher-lua for a project to allow 
users to add filtering criteria that would be highly-specific to a user, 
but I would never consider using it for implementing a general-purpose 
plugin.  

Using Lua to develop plugins in Go would be ideal IMO. It is not performant 
like Go, not type-safe like Go, debugging embedded Lua code is difficult 
compared to working with Delve and Go, and you will have to ship plugin 
source code, or embed and write to a possibly hidden directory.

For real-world plugins I'd say stick with Hashicorp's go-plugin 
 or similar as others have 
recommended, and then only fall back to Lua when you want to allow 
end-users who are not Go developers to extend your app in small ways.

P.S. You could also use JavaScript 
 instead of Lua, 
and most people are likely more familiar with that. I chose not to use a 
JavaScript package as I wanted something significantly lighter weight than 
JS.  OTOH, I am seriously considering switching out Lua and moving to 
github.com/antonmedv/expr for my use-case as it is even lighter weight 
still.

Hi all.

Of course, in case if anyone is in interest to write  plugins for Go.
I found another option for writing plugins by use Lua.
I haven't touched the example yet, but I'm giving out the link.
https://github.com/yuin/gopher-lua/

Thank you.
