Structs are not properly embedded inside types/Composition is not handled properly

[jtquach1]

When a struct is embedded inside a type, the generated TypeScript definition for that type produces a key/value pair where the key and value are named after the struct, instead of inlining the fields of the struct inside the type.

Here's an example:

tygo.yaml:

  - path: 'github.com/Drelf2018/req'

Generated TS output:

// Code generated by tygo. DO NOT EDIT.

//////////
// source: client.go

export const Omitempty: string = "omitempty";
export const UserAgent: string = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/116.0.0.0 Safari/537.36 Edg/116.0.1938.54";
export interface Client {
  Client: any /* http.Client */;
  BaseURL?: any /* url.URL */;
  Header: any /* http.Header */;
  /**
   * Client will use the value in Variables when the Field's Value starts with "$"
   */
  Variables: { [key: string]: any};
}

//////////
// source: encode.go

export type Marshaler = any;

//////////
// source: interfaces.go

export type Api = any;
export interface Get {
}
export interface Post {
}
export interface PostForm {
  Post: Post;
}
export interface PostJson {
  Post: Post;
}
export type Adder = any;
export type NamedReader = 
    any /* io.Reader */;
export type Unwrap = any;
export type BeforeRequest = any;

//////////
// source: task.go

export interface Field {
  /**
   * index in Api struct
   */
  Index: number /* int */[];
  /**
   * provided by json tag or parsed from the field name
   */
  Key: string;
  /**
   * default value used when the field value is zero
   */
  Value: string;
  /**
   * This field is ignored when it is zero, conflict with default value
   */
  Omit: boolean;
}
export interface Task {
  Body: Field[];
  Files: Field[];
  Query: Field[];
  Header: Field[];
}
export interface Any {
  Type: any /* unsafe.Pointer */;
  Value: any /* unsafe.Pointer */;
}

My knowledge of Go is beginner level, so apologies if I got something wrong. If I understand correctly, the type PostForm should be empty in terms of its generated fields (it is composed of Post).

Hey, I think the default behavior is working as it should.

You can make use of the ,extends tag, see the docs here to get the behavior I think you may be expecting.
