Markdown Wars: Choose Your Fighter
Show HN: MDV – a Markdown superset for docs, dashboards, and slides with data
Simple charts in Markdown; comments erupt: "reinventing HTML" and "just use Org or Pandoc"
TLDR: MDV lets people write reports and dashboards in plain text and drop in charts, then export to single-file web pages and PDFs. Commenters split between loving the simplicity and saying it duplicates Pandoc and Org‑mode, while others promote Markdoc, Djot, and rival dashboard tools, sparking a familiar format showdown.
MDV bursts onto the scene promising reports, dashboards, and slides from plain text Markdown—with one-line blocks for charts, stat cards, and layouts—and exports to single‑file HTML/PDF with no browser code. Sounds clean and cozy... until the comment section lit the fuse.
First explosion: the purists. One top voice warned that if MDV strays, “you just reinvent HTML.” Translation: keep the writing simple, let themes do the styling, don’t turn a text format into a programming language. Then the power users rolled in: “Why not Emacs Org‑mode?” It’s the decades‑old Swiss Army knife of documents, and yes, you can script it with Lisp. Meanwhile, the “already solved” crowd waved the Pandoc flag—claiming MDV’s big features (front matter, containers, table of contents) are old news. Others chimed in with alternatives: Evidence.dev plugged its Markdoc flavor (apparently AI models write it well, humans review it easily), and fans shouted out Djot as a more elegant Markdown heir.
Between cheers for no‑JS, single‑file exports and groans of “another flavor?”, the thread turned into Markdown Flavor Bingo—Org, Pandoc, Markdoc, Djot… collect ’em all. The mood: half “finally, simple charts without chaos,” half “tool déjà vu.” The only constant? Everyone’s got a favorite format, and they’re ready to duel with fenced code blocks and hot takes.
