Golang Package Import
问题
我正在尝试编译以下代码：
package main
import (
"fmt"
"code.google.com/p/go.text/unicode/norm"
)
func main() {
fmt.Println(norm.IsNormalString("ŋ̊"))
}
我已经安装了unicode/norm包。我使用以下命令进行编译：
go build -o ipa ipa.go
不幸的是，我得到了以下错误：
# command-line-arguments
./ipa.go:9: undefined: norm.IsNormalString
make: *** [ipa] Error 2
看起来包已经被正确导入，但我无法访问任何其成员。我尝试将调用的方法更改为norm的另一个方法，但仍然出现错误。这让我相信我对Go的包系统有一些基本的误解。

I am attempting to get the following code to compile:
package main
import (
"fmt"
"code.google.com/p/go.text/unicode/norm"
)
func main() {
fmt.Println(norm.IsNormalString("ŋ̊"))
}
I have installed the unicode/norm package. I compile with the command:
go build -o ipa ipa.go
Unfortunately, I get the following error:
# command-line-arguments
./ipa.go:9: undefined: norm.IsNormalString
make: *** [ipa] Error 2
It seems that the package is being imported correctly, but I cannot access any of its members. I have tried changing the method from being called to another from norm, but I still get the error. This leads me to believe that I'm fundamentally misunderstanding something about go's package system.

IsNormalString不是一个函数，而是Form类型的方法。例如，
package main
import (
"code.google.com/p/go.text/unicode/norm"
"fmt"
)
func main() {
fmt.Println(norm.NFC.IsNormalString("ŋ̊"))
}
输出结果为：
true
英文:
> func (Form) IsNormalString
>
> func (f Form) IsNormalString(s string) bool
>
> IsNormalString returns true if s == f(s).
IsNormalString is not a function, it's a method on type Form. For example,
package main
import (
"code.google.com/p/go.text/unicode/norm"
"fmt"
)
func main() {
fmt.Println(norm.NFC.IsNormalString("ŋ̊"))
}
Output:
true
