Go-Path, directory name, package name, file name

Let's look at an example:

1. Directory structure

Bin

Pkg

Src

Pk1

Pk2

Function1.go

Function2.go

Index.go

2. function1.go File Contents:

Package Pk3func Function_test3 ()  {println ("Function_test3")}

3. function2.go File Contents:

Package Pk3func Function_test4 ()  {println ("Function_test4")}

4. index.go File Contents

Package Mainimport "Pk1/pk2" Func Main () {pk3. Function_test4 ()}

5, run Index.go, output:

Function_test4

The following conclusions are drawn:

1. Import imported parameters are paths , not package names .

2, although the habit of the package name and directory name to ensure consistency, but this is not mandatory provisions;

3. When referencing a package member in code, use the package name rather than the directory name ;

4, in the same directory, all source files must use the same package name (because the import uses absolute path, so under the search path, the package must have a unique path, but not necessarily a unique name);
