pyhunt is a lightweight logging tool that visually represents logs for quick structural understanding and debugging.
Simply add a decorator to your functions, and all logs are automatically traced and displayed in your terminal.

Features

• Automatic Function/Method Call Tracing: Automatically records the flow of synchronous/asynchronous functions and classes with a single @trace decorator.
• Rich Colors and Tree-Structured Logs: Enhances readability with color and indentation based on call depth.
• Multiple Log Levels Supported: DEBUG, INFO, WARNING, ERROR, CRITICAL.
• Set Log Level via CLI: Manage and store HUNT_LEVEL in a .env file.
• Optimized for AI Workflows: Easily trace code generated by AI.
• Detailed Exception Information: Includes call arguments, location, and stack trace on exceptions.

Installation

Install with pip

pip install pyhunt

Install with uv

uv add pyhunt

Quick Start

1. Set Up Environment Variable File

hunt

This command sets HUNT_LEVEL=DEBUG in your .env file.

2. Apply @trace to Functions or Classes

See more examples in the examples folder.

Basic Example

from pyhunt import trace

@trace
def test(value):
    return value

Asynchronous Function

@trace
async def test(value):
    return value

Class Methods

@trace
class MyClass:
    def first_method(self, value):
        return value

    def second_method(self, value):
        return value

Using with AI

Rule Setup

Add the following rules to .cursorrules, .clinerules, or .roorules:

<logging-rules>

**Import:** Import the decorator with `from pyhunt import trace`.
**Tracing:** Use the `@trace` decorator to automatically log function calls and execution times.
**Avoid `print()`:** Do not use the `print()` function.
**Exception Handling:** Use `try`/`except` blocks and re-raise exceptions with `raise` to maintain traceback.

</logging-rules>

Modifying Existing Codebase

Command: "Modify the codebase according to the logging rules."

Logger Usage

The logger interface is recommended for use only in critical sections.
Most actions are traced via @trace, and excessive use may reduce readability.

from pyhunt import logger

logger.debug("This is a debug log.")
logger.info("This is an info log.")
logger.warning("This is a warning log.")
logger.error("This is an error log.")
logger.critical("This is a critical log.")

CLI Usage

hunt [options]

Supported Options

• --debug : DEBUG level (most detailed)
• --info : INFO level
• --warning : WARNING level
• --error : ERROR level
• --critical : CRITICAL level

If no option is specified, the default is INFO.
