[英]how can i use a function inside main package from a file in another package in GO?
Hi I want to call a method inside the main package, my project struct is like this: src: 嗨,我想在主程序包中调用一个方法,我的项目结构如下:src:
Postgres folder: Postgres文件夹:
now I want to call a method inside main package from the go files inside the postgres folder that is from postgres package. 现在我想从来自postgres包的postgres文件夹中的go文件中调用主包中的方法。 I tried to import "foo/src" then using src.Myfunction but I got an error: 我尝试使用src.Myfunction导入“ foo / src”,但出现错误:
import "foo/src" is a program, not an importable package
The package main
is supposed to be used only to implement the binary/command specific code. 软件包main
应该仅用于实现二进制/命令特定的代码。 It usually imports code from other packages to glue everything together. 它通常从其他包中导入代码以将所有内容粘合在一起。 If you need to import something from the package main
, that code is probably not specific to that command, so it should belong to another package. 如果您需要从包main
导入某些内容,则该代码可能不特定于该命令,因此它应该属于另一个包。 After you refactor the code, you can import it from the package main
and from your other package which also requires it. 重构代码后,可以从包main
和也需要它的其他包中导入它。
