缩短Go / Golang中的进口变量出口？

Question

if I have

// types.go

type S string

func (s *S) Lower() *S {
    *s = S(strings.ToLower(string(*s)))
    return s
}

`

// in another file

import "u/types"

func main() {
    s := types.S("asdf")
    if s == "asdf" {
        s.Lower()
    }
}

1. Is there a way to shorten types.S("asdf") to just S("asdf")?

2. Is there a way to lowercase method calls from other files? e.g. s.Lower() => s.lower()?

Answer 1

It's not recommended for most cases but you can do import . "u/types" and all then skip the types prefix. . will import all the public symbols into your package for you allowing you to call them as if they were local to your package.
