Re: [go-nuts] alternate struct tags for json encode/decode?

[Reed Wade]

oh, cool!

I had no idea that was doable (makes sense in retrospect but..).

That would kind of suit a lot of the cases I care about.

[go-nuts] Re: Language is a platform, which golang still does not pay attention to !!!

So -- Go's fatal flaw is you can just deploy your code and run it instead 
of having to first install heaps of libs and config and maybe a jvm first?

I'm certain that's not what was meant but that's how this reads.

I guess the "I don't use Go" bit is the telling part. It doesn't look 
complex and annoying so it must not be effective?

[go-nuts] alternate struct tags for json encode/decode?

[Reed Wade]

More than once, I've found myself wanting to do something like this:

package main

import (
 "encoding/json"
 "os"
)

type Cake struct {
 Muffin string `json:"muffin" json2:"muffin"`
 Piestring `json:"pie" json2:"-"`
 Tuna   string `json:"tuna" json2:"eel"`
}

func main() {
 c := Cake{"a", "b", "c"}
 j := json.NewEncoder(os.Stdout)
 j.Encode(c)
 j.SetTag("json2") // no such thing as this here
 j.Encode(c)
}


where I've got a struct that I sometimes want to express in json one way 
and sometimes another.

Is there a sensible existing way to do that? Would this be a useful update 
to the lib?

thanks,
