Bez generates a browser engine from specifications and tests

tangled.org 4 min read Editor score 7/10

Bez proposes generating browser engines from specifications, candidate implementations, comparisons with shipping browsers and Web Platform Tests; it also describes builds limited to features a site uses. The approach could change the cost and footprint of embedding web rendering, though the excerpt gives no results.

What: • Bez generates a web rendering engine from specifications, browser comparisons, and Web Platform Tests.
How: • Candidate implementations are checked against Chromium, Firefox, and WebKit; accepted code is committed as ordinary Rust.
Why it matters: • Content-scoped builds can omit unused features, aiming for smaller, faster-to-update engines that are easier to embed.

Bez generates and checks engine code against browser results before committing it. Sketched from the article's own text.
