libjs-test262 VS ladybird

Linus Groh of LibJS is an Invited Expert in TC39: https://linus.dev/posts/road-to-working-on-serenityos-and-la...

ECMAScript conformance test results looking good, 87-88% passing at the moment: https://libjs.dev/test262/

this is a qt frontend (definitely works on linux) for the serenityos browser engine, libweb.

this is a new, from-scratch implementation of both a modern html/css layout engine and a javascript runtime.

see https://libjs.dev/test262/ for ecmascript conformance tests.

the browser engine is far from finished but is able to display moderately complex pages like github.

it's always exciting to see a completely new web engine running in conventional environments like linux!

> Our JavaScript engine is decently mature, test262 score tracked here: https://libjs.dev/test262/

In a few years when they have achieved feature parity with Chromium or at least Safari we can discuss this again, but for now it's not ready for real life use.

See https://github.com/linusg/libjs-test262 for an example, specifically the CMake files and `src/main.cpp`.

The separate website is just to have a nice & short link to the test262 graph and whatever else we'll put there eventually; and also because it's built/deployed in a slightly different way than the main serenityos.org website.

You're in luck, Andreas has been hacking on that since a couple of months. They're calling the Linux version of the browser Ladybird: https://github.com/awesomekling/ladybird

LadyBird

Why not ladybird? https://github.com/awesomekling/ladybird

The page loads fine in Ladybird[1] on Arch. It's the browser purpose-built for SerenityOS[2] using a in-house HTTP/JS/TLS engine that hasn't matured to the point of practical usability yet. If I were a site administrator using some kind of weird metric to block a browser, this thing would definitely go on the blacklist.

As for a more common uncommon browser, GNOME Web (WebKit) also works fine.

Whatever is causing you to get blocked, it's not the browser engine you're using. Check your plugins, antivirus, MITM engines, and whatever else messes with your connection. It could also be a simple IP block because of a bad IP neighbour or a shared CGNAT server.

Ooh, ooh.

I'm on Ubuntu, and it looks like I need to upgrade to 22.04 before I can experience the build process for myself.

The repo itself is shockingly tiny: https://github.com/awesomekling/ladybird. Looks like it needs https://github.com/SerenityOS/serenity as well. https://github.com/SerenityOS/serenity/tree/master/Userland/... is 100kLoC which is also surprisingly small.
