I want to know how exactly Decaf integrates Ruby with WebKit. Is it possible to handle the DOM through both JavaScript and Ruby or you have to move completely to Ruby?

I think JavaScript and Ruby are being horribly misunderstood here...

The app will crash if you multiply 1234567890 * 9876543210 in the console. This is probably a conversion between the large integer and the inspector number types.

I am happy with decaf, though not much document, I tried exploring it

ObjectSpace.each_object does not work, I wanted to know if it has been intentionally left out or we can expect it in future

All the pages in a process share the same DOM classes. This means that one site could monkey-patch a class and breach the security of another site. For example:

window.class.send(:define_method, :window) do
  # Here, the script might have access to
  # the Window of another site.
end

There are a few ways to fix this:

• Run a new Ruby process for each frame
  This seems to be the safest bet, but would require a good amount of work. It may be automatically implemented in a multi-process architecture like Chromium.
• Define the DOM classes separately for each frame
  This shouldn't require all that much work. Each RB class currently has a static VALUE member that represents its class. We would replace this with a map of DOMWindow to VALUE. Then, we would convert RBObject::rubyClass() to RBObject::rubyClass(DOMWindow*) so that we know which window to get the class for.
• Run at a safe mode high enough to disable monkey-patching
  I don't think I like this one. Some people might want to patch classes, but they would be out of luck. We may want to raise the safe level anyway, but not because of this issue.

About half the time, the debugger won't stop on Ruby breakpoints. This sucks.

Hi, first of all, thanks for this awesome work. If there is anything that can take javascript down, it will have to run on the browser first.

Because of that, I would like to ask you if you plan on update decaf to recent webkit (or maybe Blink) and recent ruby version.

It's a shame that very few people know about this project. It's something that should definitely be on spotlight. You rock!

require 'set'
>>> "NoMethodError: undefined method `require' for #<Window:0x007f9ff2c33108>"

Kernel.require 'set'
>>> "LoadError: cannot load such file -- set"

Kernel.require 'observable'
>>> "LoadError: cannot load such file -- observable"

I get something like net/http not being available, as the DOM provides interfaces. But things like Set and Observable ought to be available, no?

Gotta say I love this as it stands. If you could make this run only one site (no url bar) ala Fluid it would be great for my purposes.

Hi @TIMahoney,

Just saw this and thought it was interesting. I'm curious, though, as to how it compares to OpalRb, another project which uses Ruby in place of JavaScript.

I assume that this follows a similar principle as Opal, in that it transpiles Ruby to JavaScript. I'm also curious if this project works outside of WebKit, and if it's active / working anymore.

I was looking for programmatically open new window from console

$window.dup crashes the app every time

You can open the inspector with a keyboard shortcut, but not the console. There should be a shortcut for the console.

open google.com search for some stuff, opens the instant result page

if I am clicking on any of the links, it does not take me to it, but if right click, copy the link, open a new window and paste it works

I believe this should be in every browser going forward. Do you? If so, how may I help?

Not finding window.ActiveXObject (expected not to), or window.XMLHttpRequest (kinda surprised).

Are these not part of the webkit idl?

Will this support Linux?
