Changelog #

0.1.0 #

Initial release.

EPUB and FB2 parsing into one shared document model: BookDocument → Chapter → ParagraphBlock / HeadingBlock / ImageBlock, down to lazy Sentence and Word spans.
bookParserFor entry point with magic-byte format detection and transparent .fb2.zip unwrapping; the archive layer (inspectBookArchive) is exported for the ambiguous cases.
A cheap parseMetadata path for both formats — the FB2 side streams events instead of building a DOM, so neither format reads chapter content to answer with a title, authors, language, and cover.
Expected failures returned as ParseResult (corrupt, unsupportedFormat, encoding, emptyDocument, drmProtected), never thrown.
Script-driven rule-based segmentation behind the replaceable TextSegmenter port, with a per-writing-system support boundary.
Language normalization against the whole of ISO-639-1, including an ISO-639-2 mapping.
Opt-in JSON serialization (package:ebook_parser/serialization.dart) versioned by kBookDocumentSchemaVersion, with image bytes handed back by reference.
