go - golang.org/x/text/message.Print 完成了什么？

Question

Printer.Print 的文档说:

Print is like fmt.Print, but using language-specific formatting.

但与 Printer.Printf 相比，我很难看到任何特定语言.

考虑:

package main

import (
    "fmt"

    "golang.org/x/text/language"
    "golang.org/x/text/message"
)

func main() {
    message.SetString(language.English, "foo", "bar")

    p := message.NewPrinter(language.English)
    p.Print("foo")
    fmt.Println()
    p.Printf("foo")
    fmt.Println()
}

结果:

foo
bar

Printer.Print 到底做了什么(特定于语言)？

Answer 1

Package message implements formatted I/O for localized strings with functions analogous to the fmt's print functions. It is a drop-in replacement for fmt.

特定于语言的行为不会将 Printer.Print 与 Printer.Printf 区分开来——而是将它们与它们的 analogous functions in the fmt package 区分开来.它就在您引用的文档中。
