viparse 0.1.2

Vietnamese-first document loader for RAG

viparse

Vietnamese-first document loader for RAG.

One command turns any Vietnamese document — including legacy TCVN3/VNI/VISCII fonts, scanned PDFs, and old .doc/.xls files — into clean Unicode NFC Markdown/JSON, ready to push into a vector DB.

Why

Generic loaders parse the file but often emit garbled diacritics (legacy fonts) or wrong Unicode normalization. viparse handles exactly that Vietnamese layer: detect & convert legacy encodings to Unicode, enforce NFC, and offer diacritic-aware OCR.

Backbone principle: never hand-write a parser. Wrap well-maintained engines behind thin adapters; if an engine gets a CVE or is abandoned, swap the adapter without touching the rest. Heavy dependencies are lazy-imported via extras (viparse[ocr], viparse[office]).

Status

Released — viparse 0.1.0 on PyPI. See docs/specs/ for the full spec map (SPEC-0 … SPEC-8) and CHANGELOG.md for release notes.

Installation

pip install viparse               # core — pure stdlib, no parser/OCR binaries
pip install "viparse[office]"     # .docx / .xlsx and legacy .doc / .xls
pip install "viparse[pdf]"        # digital PDFs
pip install "viparse[ocr]"        # scanned PDFs (needs the Tesseract binary)
pip install "viparse[all]"        # every engine

Run viparse doctor to see which engines your installed extras enable.

Usage

import viparse

docs = viparse.load("tai_lieu_cu.pdf")            # list[Document], already NFC
docs = viparse.load("bang_luong.xlsx", output="markdown", encoding="auto")

viparse ./docs/**/*.pdf -o md
viparse doctor        # list available engines per installed extras
