在进行中，如果我们要使用该文件中定义的功能，是否不需要在同一目录中导入另一个文件？

Question

in go, don't we need to import another file in same directory if we want to use function defined in that file? For example.

FolderA-
-------- FileA.go
---------FileB.go

In FileB.go, I define method Foo()

In FileA.go, I want to call Foo() which defined in FileB.go.

Do I need to import FileB in FileA.go like this?

import ("FileB")

Answer 1

No. Just call a function. Please note:

• You are not including files in Go, you include packages.
• These files should share the package.

And google is full of good info as well, ex. http://thenewstack.io/understanding-golang-packages/
