QR code renderer in a TrueType font
In the "Libre Barcode Project" discussion yesterday, 1bpp asked: "Is anyone willing to sacrifice their sanity for the sake of implementing a QR renderer as TTF hinting code?" Yes. I had some tokens to burn and was curious... turns out, it's possible. This was put together by a mix of Gemini, GPT, and Claude (depending on which usage limits kept running out).

In plain words
QR code renderer in a TrueType font encodes QR codes directly into a font file using TTF hinting code. Users can generate QR codes by selecting the font and typing text, which the font automatically converts into scannable QR patterns. Built by combining multiple AI models to overcome individual usage limits, this unusual implementation proves QR encoding is technically feasible within font hinting constraints. It's intended for anyone curious about the intersection of typography and data encoding.

This is a real TrueType/OpenType font that turns bracketed text into QR codes during text shaping. There is no separate image generation or preprocessing step: type text like [hello] , apply the font, and the font's built-in OpenType rules render the QR code. Because the QR code is still text, you can copy and paste the rendered QR block as ordinary characters, store it in plain text, or mix it inline with regular Latin text. Text outside brackets remains readable. Browser Line-Wrapping Note: Because layout engines perform line-breaking on the Unicode text before shaping, browsers may split a QR code across lines if it contains break opportunities (like spaces, dots, or slashes) and hits…from qr.jim.sh

qrframe – generate beautiful qr codes with javascript code2024 · github.com · ▲401I originally built a QR code generator as a resume project using Rust and I realized a web interface would make customization way easier. This still generates the "data" using that rust library via wasm, but the rendering is all editable javascript to make an SVG or paint on an HTML canvas. I was especially inspired by https://qrbtf.com which had some unique style options I had never seen before, which I ended up copying, and then I made some more.
Handwriter.ttf – Handwriting Synthesis with Harfbuzz WASM2024 · github.com · ▲191During the hype of llama.ttf months ago, I was speculating the potential of WASM shaper for even crazier purpose, one that fitter to a font shaper's duty -- to synthesize font at runtime. This project as proof-of-concept implements a synthesizer that generates and rasterizes handwriting-style font, backed by a super-lightweight RNN model (~14MiB).
TTF-DOOM – A raycaster running inside TrueType font hintingApr 2026 · github.com · ▲68TrueType fonts have a hinting VM that grid-fits glyphs. It has a stack, storage area, conditionals, function calls, and it turns out it's Turing-complete. So I built a raycasting engine in the hinting bytecode. The glyph "A" in the font has 16 vertical bar contours. The hinting program reads player coordinates from font variation axes via GETVARIATION, does DDA ray marching against a tile map in the storage area, and repositions bar heights with SCFS. It ends up looking like a crude Wolfenstein-style view. Small visuzlization:…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
