Load package dynamically - dynamic

Question

Is it possible to load a specific package during runtime?
I want to have a kind of plugins where each one has the same functions than the others but with different behaviour, and depending on the configuration file, load one or other.

Answer 1

No, Go doesn't support dynamically loaded libraries.
Your best bet is to start the plugin as its own executable and communicate with it through sockets or via stdin/stdout.
2017 update
This answer is no longer true, Go now supports plugins (for Linux and MacOS only as of June 2021)

Answer 2

There is support for this now as of go 1.8
https://golang.org/pkg/plugin/

Answer 3

You might consider executing the ‘plugin’ packages at runtime, by writing out a new program (say, to a temp directory) and executing via exec.Command, something along the lines of exec.Command("go", "run", files…).Run()
You’ll see some similar code here.

Answer 4

Just do these,create a codegen that reads the configuration, generates a basic go file with the packages loaded in order and then execute that, compile languages won't nor provide dynamic loading, even dart suffers in a way,simple just read your configuration file then create a temporary file with the necessary codes to load up and communicate with sockets or http

Answer 5

I think what you are looking for is the special function init
if you add a
func init() {
}
inside a package it will run it the first time the package is imported.
This happens only in the same binary. As other have already said go does not support dynamically loaded libraries.
