md-ulb-pwrap

Markdown paragraph wrapper using Unicode Line Breaking Algorithm. Includes a Rust library with Python bindings.

Wrap a Markdown paragraph using a maximum desired width. Only works for paragraphs that don't contain other container blocks. Respects the prohibition against wrapping text inside inline code blocks and links.

Rust library

cargo add md-ulb-pwrap

use md_ulb_pwrap::ulb_wrap_paragraph;

        3,
        3,
    ),
    "aaa\n``` ``  ` a b c ```\nccc",
);

Python bindings
