DOCX (ECMA-376 / ISO/IEC 29500 WordprocessingML) read and written, on the craft-wordmodel document model. Also Word XML Documents (Flat OPC, one .xml file holding the whole package) and Word 2003 XML, password-protected packages and Restrict Editing password hashes.

It is WordCraft's DOCX crate, moved onto the shared crates: craft-opc for the package, craft-xml for parsing, craft-offcrypto for encryption, craft-wordmodel for the model.

use craft_wordmodel::Document;

let doc = Document::from_text("Hello\nWorld");
let bytes = craft_docx::write(&doc).unwrap();
let back = craft_docx::read(&bytes).unwrap();
assert_eq!(back.plain_text(craft_wordmodel::StoryRef::Body), doc.plain_text(craft_wordmodel::StoryRef::Body));

Reading

read(bytes), read_with(bytes, &ReadOptions { password, chunks }), read_with_password.
read_xml(bytes): a Word XML Document or a Word 2003 XML Document, told apart by its root.
package_title(reader, max_part): the title in docProps/core.xml, inflating only that part.

The reader is lenient (unknown markup is skipped, bad numbers fall back to defaults) and bounded:

Limit	Value
ZIP entries	20,000 (checked before the archive is indexed)
One part	256 MiB
All parts	512 MiB, counting entries that fail their checksum
XML nesting	256 open elements
XML elements	8,000,000 in one part
Attributes	1,024 on one element
Word XML file	1 GiB

Markup the model does not hold is kept in Document::passthrough and the kept markup, and written back as it was read.

Writing

write(doc), write_as(doc, Flavor) for .docx, .docm, .dotx and .dotm; write_flat and write_wordml2003 for the XML forms; encrypt for a password.

Equations (OMML) are read and written by craft_math::omml.

Not here yet

DrawingML (a:) shape fills, lines, custom geometry and colours are still read with this crate's own code; they move to craft-drawingml.
