When loading a canned version of reddit.com, we end up parsing many many shadow tree style sheets of roughly ~170 KiB text each. None of them have '\r' or '\f', yet we spend 2-3 ms for each sheet just looping over and reconstructing the text to see if we need to normalize any newlines. This patch makes the common case faster in two ways: - We use TextCodec::Decoder::to_utf8() instead of process() This way, we do a one-shot fast validation and conversion to UTF-8, instead of using the generic code-point-at-a-time callback API. - We scan for '\r' and '\f' before filtering, and if neither is present, we simply use the unfiltered string. With these changes, we now spend 0 ms in the filtering function for the vast majority of style sheets I've seen so far. |

Ladybird
Ladybird is a truly independent web browser, using a novel engine based on web standards.
Important
Ladybird is in a pre-alpha state, and only suitable for use by developers
Features
We aim to build a complete, usable browser for the modern web.
Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.
Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.
At the moment, many core library support components are inherited from SerenityOS:
- LibWeb: Web rendering engine
- LibJS: JavaScript engine
- LibWasm: WebAssembly implementation
- LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
- LibHTTP: HTTP/1.1 client
- LibGfx: 2D Graphics Library, Image Decoding and Rendering
- LibArchive: Archive file format support
- LibUnicode: Unicode and locale support
- LibAudio, LibMedia: Audio and video playback
- LibCore: Event loop, OS abstraction layer
- LibIPC: Inter-process communication
How do I build and run this?
See build instructions for information on how to build Ladybird.
Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.
How do I read the documentation?
