Structural output - LoginGoogleAccount

[jan-goral]

Plan

According to the description of epic #1728, prepare a specification document for the structural output based on the following requirements:

• Identify all places that are producing console logs and list them in the specification.
• Specify dedicated types and structures for logs with places (packages and namespaces) for them.
• Specify proposition how to pass out function reference to low-level functions that producing logs.

Make sure that specification is sufficient to implement structured output without a doubt.

Command

LoginGoogleAccount

[piotradamczyk5]

Places which produce output logs

1. Printing URL to loginUserAuth#L92-93

   logLn("Visit the following URL in your browser:")
   logLn(url)

   `

2. User token saved ftl.client.google.UserAuth#L118-119

   logLn()
   logLn("User token saved to $userToken")

Structures for messages

sealed interface LoginState {
    data class LoginStarted(val url: String) : LoginState
    data class LoginFinished(val tokenLocation: String) : LoginState
}

Proposition of passing out function

• UserAuth#requestmethod will return Flow<LoginState>

• api contract will be changed
  from

  object UserAuthorization {
      interface Request : () -> Unit
  }

  to

  object UserAuthorization {
      interface Request : () -> Flow<LoginState>
  }

• LoginGoogleAcount#invoke will observe new flow and pass all collected LoginStateto out() function

• LoginCommandwill be responsible for printing correct message based on the LoginState
