**The holehe package requires six core Python libraries—termcolor, bs4 (BeautifulSoup), httpx, trio, tqdm, and colorama—which are declared in the `install_requires` list of [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py).**

Holehe is an open-source email reconnaissance tool developed by megadose that checks if an email address is registered on various online services. To perform asynchronous HTTP requests, parse HTML responses, and render colorful terminal output, the project depends on specific third-party packages defined in its installation configuration.

## Core Runtime Dependencies

According to the source code in `megadose/holehe`, the package declares six mandatory runtime requirements in the `install_requires` array located at line 11 of [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py). These dependencies are automatically installed when you use `pip install holehe`.

### termcolor

**termcolor** enables ANSI color formatting for terminal output, allowing holehe to display results in color-coded formats for better readability.

### bs4 (BeautifulSoup)

**bs4** provides the BeautifulSoup library for parsing HTML and XML documents. Holehe uses this to extract data from web service responses when checking account existence across different platforms.

### httpx

**httpx** serves as the primary HTTP client, supporting both synchronous and asynchronous requests. This modern library replaces older alternatives like `requests` and enables high-performance concurrent network operations.

### trio

**trio** is an async-await concurrency library that powers the asynchronous capabilities of httpx. Holehe leverages trio to manage concurrent checks against multiple services without blocking execution.

### tqdm

**tqdm** supplies interactive progress bars for loops and long-running tasks. When holehe processes large batches of email checks, this library provides visual feedback on operation completion status.

### colorama

**colorama** ensures cross-platform colored terminal text support, particularly on Windows systems where native ANSI color codes may not function correctly.

## Where Dependencies Are Declared

The canonical source for dependency specifications is [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py) in the repository root. The `install_requires` parameter explicitly pins the six required packages, ensuring consistent behavior across different installation environments.

```python

# Conceptual representation of setup.py structure

from setuptools import setup, find_packages

setup(
    name='holehe',
    # ... other metadata ...

    install_requires=[
        'termcolor',
        'bs4',
        'httpx',
        'trio',
        'tqdm',
        'colorama',
    ],
)

```

This declaration ensures that `pip` resolves and installs all necessary libraries before holehe executes.

## How Dependencies Power holehe's Functionality

In [`holehe/core.py`](https://github.com/megadose/holehe/blob/main/holehe/core.py), the `Holehe` class orchestrates the core checking logic by integrating these dependencies. The module uses **httpx** for dispatching network requests, **trio** for managing async contexts, **bs4** for parsing response content, and **tqdm** for displaying progress indicators during batch operations.

```python

# Example: Using holehe with its dependencies

from holehe.core import Holehe

# Initialize checker with target email

checker = Holehe(email="target@example.com")

# Execute checks (internally uses httpx, trio, bs4, tqdm)

results = checker.run_all()

# Display results with colorama/termcolor support

for service, data in results.items():
    status = "Found" if data['exists'] else "Not found"
    print(f"{service}: {status}")

```

The [`holehe/__init__.py`](https://github.com/megadose/holehe/blob/main/holehe/__init__.py) file serves as the package entry point, ensuring all dependencies are properly loaded when the module is imported.

## Installing holehe and Verifying Dependencies

Install the package and all dependencies using pip:

```bash

# Install holehe and dependencies automatically

pip install holehe

# Verify specific dependency installation

python -c "import pkg_resources, pprint; pprint.pprint([d.project_name for d in pkg_resources.working_set if d.project_name.lower() in {'termcolor','bs4','httpx','trio','tqdm','colorama'}])"

```

This installation process reads the `install_requires` list from [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py) and downloads compatible versions of each library from PyPI.

## Summary

- **Six core dependencies** are required: termcolor, bs4, httpx, trio, tqdm, and colorama.
- **Declaration location**: All dependencies are listed in the `install_requires` array of [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py).
- **Core integration**: [`holehe/core.py`](https://github.com/megadose/holehe/blob/main/holehe/core.py) utilizes httpx for networking, trio for async operations, bs4 for HTML parsing, and tqdm/colorama/termcolor for UI enhancement.
- **Installation method**: Standard `pip install holehe` automatically resolves and installs all requirements.

## Frequently Asked Questions

### What Python version is required for holehe?

The [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py) configuration and source code in [`holehe/core.py`](https://github.com/megadose/holehe/blob/main/holehe/core.py) indicate that holehe requires Python 3.6 or higher to support the async/await syntax used with **trio** and **httpx**. The `trio` library specifically requires modern Python coroutine support.

### Can I run holehe without installing all dependencies?

No, holehe cannot function without its declared dependencies. The `Holehe` class in [`holehe/core.py`](https://github.com/megadose/holehe/blob/main/holehe/core.py) imports these libraries directly at the module level. Attempting to run the code without them will raise `ModuleNotFoundError` exceptions during initialization.

### Are there any optional dependencies for holehe?

Based on the [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py) source analysis, holehe does not declare optional extras in `extras_require`. All six packages—termcolor, bs4, httpx, trio, tqdm, and colorama—are mandatory runtime requirements for basic functionality.

### How do I update holehe dependencies to the latest versions?

Run `pip install --upgrade holehe` to update the main package. To upgrade individual dependencies while respecting holehe's version constraints, use `pip install --upgrade termcolor bs4 httpx trio tqdm colorama`. The [`setup.py`](https://github.com/megadose/holehe/blob/main/setup.py) configuration ensures compatibility between these packages during updates.
