在节俭的生成代码中控制golang注释

Question

I have a message from thrift that I would like to be able to serialize into and out of json, but I don't want the generated json keys to match what is in the generated go code.

Is there a way to control what annotations are attached to the struct in the go code that thrift generates?

Scratch my previous answer - it's undocumented, but it IS possible, I found it by reading the compiler code. Bah.

But anyway, in thrift's master (1.0-dev), here's how it's done - using a go.tag annotation.

This piece of thrift code:

struct foo {
  1: string bar (go.tag = "json:\"baz\" yo:\"dawg\""),
  2: string bang
}

Generates the following Go code:

type Foo struct {
        Bar  string `thrift:"bar,1" json:"baz" yo:"dawg"`
        Bang string `thrift:"bang,2" json:"bang"`
}
