展示HN：Aurora – 一个用Rust编写的浏览器引擎实验
我正在构建Aurora，这是一个早期阶段的Rust浏览器引擎。
目前，它实现了一个最小的端到端流程：解析一个狭窄的HTML子集，构建DOM树，从样式标签解析CSS，计算基本样式，推导一个简单的块布局树，并将结果绘制到一个小的文本帧缓冲区。它还包括基本的HTTP/HTTPS获取功能，并支持重定向。
JavaScript执行是通过Boa JavaScript引擎集成的。虽然这仍处于早期阶段，但简单的脚本可以运行。
渲染是从头开始在GPU上完成的，使用了wgpu和Vello，而不依赖于Skia。渲染器使用单个图集和一个简单的管道进行批处理和光栅化。
我们的目标不是构建一个完整的浏览器，而是以小而明确的方式理解和实现管道的核心部分。
接下来的步骤包括改进标记化，扩展CSS支持，使布局不那么原始，并继续在GPU渲染路径上的工作。

I’ve been building Aurora, an early-stage browser engine in Rust.<p>It currently implements a minimal end-to-end pipeline: parsing a narrow HTML subset, building a DOM tree, parsing CSS from style tags, computing basic styles, deriving a simple block layout tree, and painting the result into a small text framebuffer. It also includes basic HTTP/HTTPS fetching with redirect support.<p>JavaScript execution is integrated using the Boa JavaScript engine. This is still early, but simple scripts do run.<p>Rendering is done on the GPU from scratch using wgpu and Vello, without relying on Skia. The renderer uses a single atlas and a simple pipeline for batching and rasterization.<p>The goal is not to build a full browser, but to understand and implement the core pieces of the pipeline in a small and explicit way.<p>Next steps are improving tokenization, expanding CSS support, making layout less primitive, and continuing work on the GPU rendering path.<p>Current render snapshot : <a href="https://imgur.com/a/NtbgR5i" rel="nofollow">https://imgur.com/a/NtbgR5i</a>
