Display Functions

The display functions provide a standardized way to format and display agent interactions, tool calls, reflections, and other outputs in PraisonAI. These utilities ensure consistent formatting across all agent interactions.

​
display_tool_call

Displays a tool being called by an agent. 
def display_tool_call(

)

​
display_error

Displays an error message with proper formatting. 
def display_error(
    error_type: str,
    error_message: str,
    agent_name: Optional[str] = None
) -> None
Parameters:
  • error_type (str): Type of error (e.g., “ValidationError”, “ConnectionError”)
  • error_message (str): The error message
  • agent_name (str, optional): Name of the agent that encountered the error
Example: 
display_error(
    error_type="APIError",
    error_message="Rate limit exceeded. Please try again later.",
    agent_name="WeatherAgent"
)

​
display_generating

Displays a generating/thinking indicator for long-running operations. 
def display_generating(
    agent_name: str,
    action: str = "Thinking"
) -> None
Parameters:
  • agent_name (str): Name of the agent that is processing
  • action (str, optional): Description of what the agent is doing. Defaults to “Thinking”
Example: 
display_generating(
    agent_name="CodeAgent",
    action="Generating code solution"
)

​
clean_triple_backticks

Removes triple backticks from code blocks for clean display. 
def clean_triple_backticks(text: str) -> str
Parameters:
  • text (str): Text containing triple backticks
Returns:
  • str: Text with triple backticks removed
Example: 
code = """```python
def hello():
    print("Hello World")
```"""

clean_code = clean_triple_backticks(code)
# Returns: "def hello():\n    print(\"Hello World\")"

​
Callback Functions

​
register_display_callback

Registers a custom display callback function for handling display events. 
def register_display_callback(
    callback: Callable,
    event_types: Optional[List[str]] = None
) -> None
Parameters:
  • callback (Callable): The callback function to register
  • event_types (List[str], optional): List of event types to register for. If None, registers for all events
Event Types:
  • "interaction": Agent-to-agent or agent-to-user interactions
  • "reflection": Self-reflection events
  • "instruction": Instruction events
  • "tool_call": Tool calling events
  • "error": Error events
  • "generating": Processing/generating events
Example: 
def custom_logger(event_type, data):
    print(f"[{event_type}] {data}")

register_display_callback(
    callback=custom_logger,
    event_types=["interaction", "error"]
)

​
sync_display_callbacks

Context manager for synchronous display callbacks. 
@contextmanager
def sync_display_callbacks() -> None
Example: 
with sync_display_callbacks():
    # All display events within this context will be processed synchronously
    agent.run("Analyze the data")

​
async_display_callbacks

Context manager for asynchronous display callbacks. 
@asynccontextmanager
async def async_display_callbacks() -> None
Example: 
async with async_display_callbacks():
    # All display events within this context will be processed asynchronously
    await agent.arun("Analyze the data")

​
Error Logging

​
error_logs

Retrieves error logs for debugging and monitoring. 
def error_logs(
    agent_name: Optional[str] = None,
    limit: Optional[int] = None,
    error_type: Optional[str] = None
) -> List[Dict[str, Any]]
Parameters:
  • agent_name (str, optional): Filter logs by agent name
  • limit (int, optional): Maximum number of logs to return
  • error_type (str, optional): Filter logs by error type
Returns:
  • List[Dict[str, Any]]: List of error log entries
Example: 
# Get all error logs
all_errors = error_logs()

# Get last 10 errors for a specific agent
agent_errors = error_logs(agent_name="DataAgent", limit=10)

# Get all API errors
api_errors = error_logs(error_type="APIError")

​
Best Practices

  1. Consistent Display: Use display functions instead of print() for consistent formatting
  2. Error Handling: Always use display_error() for errors to ensure they’re properly logged
  3. Custom Callbacks: Register callbacks early in your application lifecycle
  4. Performance: Use async callbacks for high-volume display events
  5. Debugging: Use error_logs() to retrieve historical error information

Example: Complete Display Flow

from praisonaiagents import (
    Agent,
    display_instruction,
    display_generating,
    display_interaction,
    display_error,
    register_display_callback,
    error_logs
)

# Register a custom logger
def log_to_file(event_type, data):
    with open("agent_logs.txt", "a") as f:
        f.write(f"[{event_type}] {data}\n")

register_display_callback(log_to_file)

# Create and run agent
agent = Agent(name="AnalysisAgent", instructions="Analyze data trends")

# Display the instruction
display_instruction("AnalysisAgent", "Analyze Q4 sales data")

# Show processing
display_generating("AnalysisAgent", "Analyzing data")

try:
    result = agent.run("What are the key trends in Q4?")
    display_interaction("User", "AnalysisAgent", "What are the key trends in Q4?", "user", "agent")
    display_interaction("AnalysisAgent", "User", result, "agent", "user")
except Exception as e:
    display_error("RuntimeError", str(e), "AnalysisAgent")

# Check for errors
errors = error_logs(agent_name="AnalysisAgent")
if errors:
    print(f"Found {len(errors)} errors")
