Question

go

Addendum to this question
Here I have created a global variable for the main package. Now I need to pass this variable to all other packages. How can this be done without explicit passing during a function call from another package? Thanks in advance.

No way.

To you at first the book to esteem, manuals. And then ask questions.

For this you need to put in a corner!

Answer 4

Here is a good transfer mechanism, with goodies and reservations, called environment-variables.
And access to the database can be treated as an environment variable

Use it to your health, but in moderation.

package conf

func init() {
//Здесь может быть, к примеру, погрузка данных из конфигурационных файлов
      s:="hello global world";
      os.Setenv("MyGlobalEnv", s);
}

package my_programm

func main() {
   fmt.Println("global_var:", os.Getenv("MyGlobalEnv"))
}

and do not pay attention to the trolls with amazing "angles", "manuals", "bullets" and "nothing" they also need to somehow maintain their CSF
