Golang:按照源代码中的显示方式打印结构

Similar to this question but not quite identical.

I'm doing some code-generation, making .go files from within Go. I've got a struct, and I want to generate the text representation of it so that I can insert it as a literal into the generated code.

So, if I had myVal := SomeStruct{foo : 1, bar : 2}, I want to get the string "SomeStruct{foo : 1, bar : 2}".

Is this possible in Go?

    From the fmt package:

    %#v   a Go-syntax representation of the value
    

    This is as close as you can come with built-in formatting, after removing the package identifier (main. in this example) from the output.

    type T struct {
        A string
        B []byte
    }
    
    fmt.Printf("%#v
    ", &T{A: "hello", B: []byte("world")})
    
    // out
    // &main.T{A:"hello", B:[]uint8{0x77, 0x6f, 0x72, 0x6c, 0x64}}
    

    Run
