The Gallery

What is this showcase?

This is a community-driven gallery collecting cool demos, experiments, and projects built with Pretext. Projects are surfaced via embedded tweets so you can see the work in context, follow the creators, and join the conversation.

What’s possible with Pretext

DOM-Free Measurement

Measure text height and layout without triggering browser reflow. Pure arithmetic after a one-time prepare step.

Blazing Fast

~1500x faster than DOM-based measurement in worst cases. layout() runs in ~0.09ms for 500 text blocks.

Full i18n Support

CJK line breaking, bidirectional text (Arabic, Hebrew), emoji width correction, and locale-aware word boundaries.

Manual Line Control

Access individual line coordinates for rendering to Canvas, SVG, or WebGL. Walk line ranges, iterate lines one at a time.

Shrink-Wrap & Obstacles

Find the tightest container width that preserves line count. Flow text around floated elements with per-line width adjustments.

Virtual Scrolling

Predict paragraph heights without mounting to the DOM. Enable proper list virtualization without guesswork.
