Forked from https://github.com/luci/go-render

This fork adds an "AsCode" function to do everything render.Render previously did, but clean up output to be re-usable as code. The direct render.AsCode string output can be pasted as a new struct without modification and the go linter will be happy.

The render package implements a more verbose form of the standard Go string formatter, fmt.Sprintf("%#v", value), adding:

• Pointer recursion. Normally, Go stops at the first pointer and prints its address. The render package will recurse and continue to render pointer values.
• Recursion loop detection. Recursion is nice, but if a recursion path detects a loop, render will note this and move on.
• Custom type name rendering.
• Deterministic key sorting for string- and int-keyed maps.
• Testing!

Call render.Render and pass it an interface{}.

For example:

type customType int
type testStruct struct {
        S string
        V *map[string]int
        I interface{}
}

a := testStruct{
        S: "hello",
        V: &map[string]int{"foo": 0, "bar": 1},
        I: customType(42),
}

fmt.Println("Render test:")
fmt.Printf("fmt.Printf:    %#v\n", a)))
fmt.Printf("render.Render: %s\n", Render(a))

Yields:

fmt.Printf:    render.testStruct{S:"hello", V:(*map[string]int)(0x600dd065), I:42}
render.Render: render.testStruct{S:"hello", V:(*map[string]int){"bar":1, "foo":0}, I:render.customType(42)}
