betteroffice-docx

The typed native Rust API for opening, inspecting, editing, laying out, and saving DOCX documents. Parsing and serialization use the native OOXML model, while paragraph edits use the Yrs-backed editing core without crossing a JSON or wasm boundary.

use betteroffice_docx::{Document, get_paragraph_text};

let mut document = Document::open(&docx_bytes)?;
let paragraph_id = document.paragraphs()[0].para_id.clone().unwrap();

document.replace_paragraph_text(&paragraph_id, "Updated in Rust")?;
assert_eq!(get_paragraph_text(document.paragraph(&paragraph_id).unwrap()), "Updated in Rust");

let saved = document.save()?;
# Ok::<(), betteroffice_docx::Error>(())

DocumentModel exposes the body, sections, headers, footers, notes, styles, numbering, relationships, media, and charts. Saving replaces engine-owned DOCX parts while retaining the original package as the source for unowned parts.

The high-level paragraph replacement currently accepts plain single-run paragraphs. The complete native EditingDoc and its typed operation vocabulary are re-exported for advanced editing workflows.

Pagination accepts a typed, already-measured LayoutInput and returns both the typed layout and body display list. Native DOCX-model lowering and measurement are not yet exposed by the lower crates, so callers must currently provide that projection.

Publishing remains disabled until docx-parse, docx-layout, and docx-edit are publishable dependencies. The API is experimental and may change before 0.1.0.
