Hey, currently the only way to exclude some structs from being generated is to provide a list of files to exclude. However, this is not always convenient, often structs live close to the code where they are used.

I'd like to propose an alternative approach. The idea would be to allow the user to generate typescript types only for fields that matches certain struct tags.

In practice, it would looks like this:

packages:
    - path: "pathToMyPackage"
    output_path: "src/types/index.ts"
    optional_type: "default"
    # only includes struct fields with a json tag
    match_tags:
      - "json"

• Input

package pkg

type User struct {
	Username         string `json:"username"`
	Password          string
}

• output

export interface User {
  username: string;
}

For my use case, I'd like to exposes only struct with json tags, I'm currently using a fork of your library for my project https://github.com/fkhadra/tygo. My implementation support any specific struct tag ofc, it's not limited to json.

I also added a feature to prevent empty structs from being generated.

packages:
    - path: "pathToMyPackage"
    output_path: "src/types/index.ts"
    optional_type: "default"
    exclude_empty_structs: true
    match_tags:
      - "json"

If you think that those features are worth adding to the library, I would be happy to open a pull request.
