Shannon Booth f8288a14cc LibWeb/BindingsGenerator: Simplify weird dictionary member assignment
Remove the special case assignment path for string dictionary members.
The old logic was using the outer dictionary conversion’s optional and
optional_default_value state to decide how to assign an individual
member, which was very confusing and not correct.

This was probably needed on earlier buggier versions of the IDL
generator working around the wrong problem.

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
  • LibUnicode: Unicode and locale support
  • 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?

Code-related documentation can be found in the documentation folder.
