Technical Report: Async Chat Stream Processing System

System Initialization

1. Project Setup

# Folder structure initialization
LOGS_FOLDER = "logs"
CHATS_FOLDER = "chats"
TASKS_FOLDER = "task_lists"

def create_log_folders() -> None:
def create_chat_folders() -> None:

Key Features:

  • Early logging setup
  • Structured folder creation
  • Error handling during startup
  • Path validation

2. Logging Configuration

logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(funcName)s:%(lineno)d - %(message)s',
    handlers=[
        logging.FileHandler(Path(get_project_root()) / LOGS_FOLDER / 'async_chat_stream.log'),
        logging.StreamHandler()
    ]
)
  • Centralized logging
  • Detailed formatting
  • Multi-handler output
  • Debug capabilities

System Architecture Overview

Core Components

  1. Enhanced Task and Chat Management System

    def get_available_lists() -> List[Path]:
def display_available_lists() -> Optional[str]:
def save_conversation_as_tasks(conversation: List[Dict[str, str]], 
                             filename: str, 
                             append: bool = False) -> None:
    • List discovery and selection
    • Append functionality for existing lists
    • Automatic index continuation
    • Metadata preservation

  2. Interactive Chat Interface

    def display_chat_menu() -> str:
async def chat_mode(client: ollama.AsyncClient, model: str) -> None:
    • Enhanced save options
    • Append to existing chats/lists
    • Context preservation
    • State management

  3. File System Organization

    LOGS_FOLDER = "logs"
CHATS_FOLDER = "chats"
TASKS_FOLDER = "task_lists"
    • Structured logging system
    • Organized chat storage
    • Task list management
    • Automatic folder creation

  4. Logging System

    logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(name)s - %(levelname)s - %(funcName)s:%(lineno)d - %(message)s',
    handlers=[
        logging.FileHandler(Path(get_project_root()) / LOGS_FOLDER / 'async_chat_stream.log'),
        logging.StreamHandler()
    ]
)
    • Centralized logging location
    • Enhanced format with line numbers
    • Dual output streams
    • Contextual error tracking

Technical Implementation Details

Task List Enhancement

  1. List Management

    def get_available_lists() -> List[Path]:
    task_path = get_project_root() / TASKS_FOLDER
    return sorted(task_path.glob('*.csv'))
    • Automatic list discovery
    • Sorted presentation
    • Path validation
    • Error handling

  2. Append Functionality

    def save_conversation_as_tasks(conversation, filename, append=False):
    mode = 'a' if append else 'w'
    # Get last index from existing file if appending
    last_index = 0
    if append and task_path.exists():
        # Index continuation logic
    • Seamless content addition
    • Index continuation
    • Content separation
    • Format preservation

Chat System Enhancement

  1. Chat State Management

    • Conversation context preservation
    • Multiple save points
    • Append capabilities
    • History recovery

  2. File Operations

    • Atomic write operations
    • Append mode handling
    • Index tracking
    • Error recovery
