SmallDocs – Markdown without the frustrations▲92
Hi HN, I’d like to introduce you to SmallDocs (https://sdocs.dev). SDocs is a CLI + webapp to instantly and 100% privately elegantly preview and share markdown files. (Code: https://github.com/espressoplease/SDocs) The more we work with command line based agents the more `.md` files are part of our daily lives. Their output is great for agents to produce, but a little bit frustrating for humans: Markdown files are slightly annoying to read/preview and fiddly to share/receive. SDocs was built to resolve these pain points. If you `sdoc…

Rudoc – a 4.5MB Rust document converter▲17
I built Rudoc because I wanted a smaller tool for simple file convertion workflow. (Pandoc was so heavy for me) I once wanted to try Pandoc, but after I downloaded it from GitHub, I found that it is around 70 MB. It also needed a lot of dependencies. Rudoc is not a substitue of Pandoc, it supports limited set of formats (only txt, md, html, typ, docx, pdf, pptx, xml, json) and doesn't support advanced formatting. The most common workflow is just turn a markdown file to a html. PDF generation can work without Typst, but PDF input conversion requires Typst as a backend. It has no other runtime…
