template: constants should be generated with type?

[luryson]

Describe the bug

const definition is generated without specified type.
eg.
xxx.thrift

typedef string MyString 
const MyString OK = "ok"
const MyString Err = "err"

const i32 StatusOK = 200
const i32 StatusErr = 500

got:

const (
	OK = "ok"

	Err = "err"

	StatusOK = 200

	StatusErr = 500
)

type MyString = string

To Reproduce

Steps to reproduce the behavior:

thriftgo --gen go --out xxx xxx.thrift

Expected behavior

constants should be generated with type like

const (
	OK MyString = "ok"

	Err MyString = "err"

	StatusOK int32 = 200

	StatusErr int32 = 500
)

type MyString = string

May I ask what is the necessity of doing this? It seems that the current way is also okay.

[luryson]

It's confusing for client users to find optional values of that type. In my opinion, when typedef types and corresponding values are defined, it is to inform users of the available values of that type.

Currently we don't have plan to support this. If you're interested in it, you can create a pr to implement it and add some tests.
