Instance Method Details

#call(response) ⇒ OllamaChat::FollowChat

Invokes the chat flow based on the provided Ollama server response.

The response is expected to be a parsed JSON object containing information about the user input and the assistant’s response.

If the response indicates an assistant message, this method:

1. Ensures that an assistant response exists in the message history (if not already present).
2. Updates the last message with the new content and thinking (if applicable).
3. Displays the formatted terminal output for the user.
4. Outputs the voice response (if configured).

Regardless of whether an assistant message is present, this method also outputs evaluation statistics (if applicable).

Parameters:

  • response (Ollama::Response) —

    The parsed JSON response from the Ollama server.

Returns:
