hwpxkit 0.2.0

Python bindings for HWP/HWPX document parser

hwpx

Python bindings for HWP/HWPX document parser.

The package is backed by Rust and ships CPython 3.8+ abi3 wheels. CPU-bound parse and conversion APIs release the Python GIL while Rust code is running.

Installation

pip install hwpxkit

Or install from source:

# Install maturin first
pip install maturin

# Build and install
cd packages/hwpx-python
maturin develop

Build Wheel

cd packages/hwpx-python

# Using uv (recommended). Builds a CPython 3.8+ abi3 wheel.
uv tool run maturin build --release --locked --compatibility pypi --out dist

# Or using maturin directly
maturin build --release --locked --compatibility pypi --out dist

The built wheel will be in the dist/ directory.

Usage

Parse a document

import hwpx

# Parse from file path
doc = hwpx.parse_file("document.hwpx")

# Or parse from bytes
with open("document.hwpx", "rb") as f:
    doc = hwpx.parse(f.read())

Convert to Markdown

# Basic conversion
markdown = doc.to_markdown()
print(markdown)

# With options
markdown = doc.to_markdown(
    use_html=True,           # Use HTML tags for tables, etc.
    include_version=True,    # Include document version
    image_output_dir="./images"  # Save images to directory
)

Convert to HTML

html = doc.to_html()

# Save images to directory instead of base64
html = doc.to_html(image_output_dir="./images")

Get plain text

text = doc.get_text()
print(text)

Convert to JSON

json_str = doc.to_json()
print(json_str)

Parser diagnostics

report = doc.diagnostic_report()
print(report["summary"])
for item in report["items"]:
    print(item["severity"], item["category"], item["message"])

doc.warnings remains available for string compatibility.

Working with untrusted documents

HWP/HWPX input is treated as untrusted. The Rust parser enforces HWPX ZIP, XML, and section resource limits and returns structured diagnostics for unsupported or lossy content. hwpx.parse_file() rejects source files larger than 512 MiB before reading them into memory; callers that use hwpx.parse(bytes) are responsible for bounding the bytes they pass in. See the repository security model for details.

Document properties

# Get document version
print(doc.version)  # e.g., "5.1.0.1"

# Get number of sections
print(doc.section_count)

Supported Formats

• HWP 5.0: Binary format (Hangul Word Processor)
• HWPX: XML-based format (OWPML standard)
