Language Bindings

The Python and TypeScript packages are thin wrappers over the Rust core. The Rust library exposes the same document model directly, and the CLI uses the same engine for inspection and extraction.

Python​

import dongler

doc = dongler.load("report.pdf")

doc.metadata
doc.pages
doc.to_markdown()
doc.to_latex()
doc.to_json()
doc.to_dict()

to_json() returns a JSON string. to_dict() returns a native Python dict.

TypeScript​

import { load } from "@cristianexer/dongler";

const doc = load("report.pdf");

doc.metadata;
doc.pages;
doc.toMarkdown();
doc.toLatex();
doc.toJson();
doc.toObject();

toJson() returns a JSON string. toObject() returns the typed document data.

Rust​

let doc = dongler_core::load_path("report.pdf")?;
let markdown = doc.to_markdown()?;
let json = doc.to_json()?;

PDF documents expose the same render methods plus rich page/block fields such as bbox, source_anchors, images, and warnings.
