scrybe-py 0.4.0

Scrybe — MCP-native Markdown editor library (Rust-backed). Provides the `scrybe` import package.

scrybe-py

PyO3 bindings that expose scrybe-core and scrybe-render to Python as the scrybe._rust native extension module. Python on the outside, Rust on the inside — this crate is the seam between the two.

What it does

Wraps the Rust Document, ContentId, and render_html in Python-callable classes and functions. Python code (the scrybe package, plugins, and the gila scrybe CLI integration) calls these via the compiled extension module without any Rust toolchain at runtime.

Role in the architecture

scrybe-py is a thin translation layer. It re-exports scrybe-core and scrybe-render types directly and adds only the PyO3 #[pyclass] wrappers needed for the Python boundary. The module is built with maturin and installed as scrybe/_rust.so (Linux/macOS) or scrybe/_rust.pyd (Windows).

Key public types and entry points

Python name	Rust source	Description
scrybe._rust.Document	scrybe_core::Document	Load, inspect, and render Markdown; content_id(), render_html(theme?), ast_title()
scrybe._rust.ContentId	scrybe_core::ContentId	ContentId.of(bytes), verify(bytes), as_hex()
scrybe._rust.render_markdown(source, theme?)	scrybe_render::render_html	One-shot render without opening a Document object

The python feature gate controls whether PyO3 bindings are compiled in. The crate can also be used as a plain Rust library (re-exporting core types) without the feature.

Build and test

# Build the Python extension (editable install into active venv)
maturin develop --features python,extension-module

# Run Rust unit tests (no Python required)
cargo test -p scrybe-py

# Smoke test from Python
python -c "from scrybe._rust import Document; d = Document('# Hi'); print(d.content_id())"

Requires maturin (pip install maturin) and a Rust toolchain. The workspace Cargo.toml pins pyo3 = "0.28" with auto-initialize.
