Description

Hey HN,I built libreoffice-rs: a pure-Rust, std-only library + CLI for reading, writing, converting, and rendering office documents — with *zero* LibreOffice, Java, or C dependencies.100x faster... I know, I know.It supports DOCX, XLSX, PPTX, ODT/ODS/ODP, PDF, Markdown, CSV, HTML, SVG, and more. The CLI is designed to feel familiar:```bash cargo install libreoffice-pure# soffice-style usage libreoffice-pure --headless --convert-to pdf report.docx libreoffice-pure --headless --convert-to csv spreadsheet.xlsx# Markdown extraction libreoffice-pure docx-to-md report.docx report.md libreoffice-pure pptx-to-md slides.pptx slides.md# Render pages as images libreoffice-pure docx-to-pngs report.docx pages/ --dpi 144 ```

Could you build this?

No Writing a pure-Rust, zero-dependency library to parse, render, and convert complex binary and XML document formats (DOCX, PPTX, PDF) matches millions of lines of intricate specification and rendering logic.

What it would actually take: Requires implementing comprehensive parsers for OOXML, ODF, and PDF specifications, alongside custom typography, font rendering, text shaping, layout engines, and vector rasterizers in Rust. The primary obstacle is reverse-engineering or faithfully implementing thousands of edge cases in legacy document formats and paginated layout algorithms to match visual parity with Microsoft Office and LibreOffice. It requires a dedicated team of systems programmers with deep expertise in document standards, font shaping (e.g., HarfBuzz equivalents), and 2D graphics layout engines.
