**The Python extractor script is located at [`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py) in the root of the virgiliojr94/book-to-skill repository.**

The `book-to-skill` project provides a dedicated extraction utility that processes documents and converts them into skill mappings. Understanding the **Python extractor script location** and its relationship to the underlying package structure is essential for both command-line usage and programmatic integration.

## Exact File Path of the Extractor Script

The primary entry point for document extraction resides in the repository's `scripts` directory:

- **File:** [`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py)
- **Repository:** virgiliojr94/book-to-skill

This file functions as a lightweight bootstrapper rather than containing the core logic. When executed, [`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py) performs deterministic environment preparation—specifically forcing UTF-8 I/O streams and adjusting `sys.path`—before delegating execution to the package's command-line interface in [`book_to_skill/cli.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/cli.py). This architecture ensures consistent behavior whether the tool is invoked as a standalone script or installed as a console-script entry point.

## How the Extractor Script Works

The extraction pipeline follows a layered design that separates entry-point logic from implementation details.

**[`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py)** handles:

- UTF-8 stream initialization to prevent encoding errors during document processing
- Path manipulation to ensure the `book_to_skill` package imports correctly when run directly from source
- Delegation to the CLI main function

**[`book_to_skill/cli.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/cli.py)** implements the actual command-line interface, parsing arguments and orchestrating the workflow.

**[`book_to_skill/utils.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/utils.py)** contains the core `main` function that performs the actual extraction logic, invoked by the CLI layer.

## Running the Python Extractor

Depending on your integration needs, you can invoke the extractor through multiple entry points.

### Command-Line Usage

Execute the wrapper script directly from the repository root:

```bash
python scripts/extract.py <path-to-document>

```

This method uses the bootstrapper to initialize the environment before processing begins.

### Programmatic Usage

Import the extraction pipeline directly into your Python code to bypass the CLI argument parsing:

```python
from book_to_skill.utils import main as skill_main

# Directly invoke the same processing pipeline that the CLI uses

skill_main()

```

This approach is ideal for testing or when integrating the extractor into larger automation workflows.

### Testing the CLI Entry Point

For integration tests that require the full CLI flow—including UTF-8 stream handling and argument parsing—import the CLI module directly:

```python
from book_to_skill.cli import main as cli_main

# Executes the full CLI flow (including UTF-8 stream handling)

cli_main()

```

## Related Source Files in the Extraction Pipeline

Understanding the full call chain helps when debugging or extending functionality:

- **[`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py)** — Thin wrapper that sets up UTF-8 streams, adjusts import paths, and calls the CLI entry point.
- **[`book_to_skill/cli.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/cli.py)** — Implements the command-line interface that drives the extraction process.
- **[`book_to_skill/utils.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/utils.py)** — Contains the core `main` function invoked by the CLI to perform the actual document processing and skill extraction.

## Summary

- The **Python extractor script location** is [`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py) at the repository root.
- The script acts as a bootstrapper that configures UTF-8 I/O and `sys.path` before delegating to [`book_to_skill/cli.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/cli.py).
- You can run the extractor via command line, import the core logic from `book_to_skill.utils`, or test the full CLI through `book_to_skill.cli`.
- The architecture separates entry-point concerns from extraction logic, enabling both script-based and package-based usage patterns.

## Frequently Asked Questions

### Where exactly is the Python extractor script located in the repository?

The Python extractor script is located at [`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py) in the virgiliojr94/book-to-skill repository. This path serves as the primary entry point for running the extraction tool directly from source.

### What does the extract.py script do besides running the extractor?

[`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py) performs critical environment setup before extraction begins. It forces UTF-8 I/O encoding to prevent character decoding errors and adjusts `sys.path` to ensure the `book_to_skill` package imports correctly when the script is executed directly from the command line.

### Can I use the extractor without calling scripts/extract.py?

Yes. You can import the extraction logic directly from `book_to_skill.utils` and call the `main()` function programmatically, bypassing the CLI wrapper entirely. Alternatively, you can import `main` from `book_to_skill.cli` to execute the full command-line flow including argument parsing.

### Why is the extractor logic split across multiple files?

The separation follows software engineering best practices: [`scripts/extract.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/scripts/extract.py) handles environment bootstrap specific to direct script execution, [`book_to_skill/cli.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/cli.py) manages command-line interface concerns, and [`book_to_skill/utils.py`](https://github.com/virgiliojr94/book-to-skill/blob/main/book_to_skill/utils.py) contains the platform-agnostic extraction logic. This modularity allows the same codebase to function as both a standalone script and an installed package entry point.
