I abhor Earth Hour

2013-03-22T13:20:03Z

So said Canadian Economics Professor Ross McKitrick in 2009 when asked by a
journalist for his thoughts on the importance of Earth Hour. I've just been
reminded that it's coming up all over again
<[link]>tomorrow. Ross went on:

Abundant, cheap electricity has been the greatest source of human

Ohh sorry, I'm thinking about Harmony... Harmony combines johnson and
envjs...

But doesn't Johnson already use Envjs? Shouldn't Johnson load env.js's
setTimeout code?

You could try something like envjs ([link]) or try to pull the timer code from there.
setTimeout is part of the browser environment, not part of javascript.

setTimeout, async script loading, and head.js

2011-02-07T17:01:58Z

Is there anyway to test scripts that load other scripts asynchronously with
head.js(...)?
script 1:
// ...
head.js("/path/to/script2.js", "/path/to/script3.js", callback);
// ...
I want to test the functionality in the callback function, but it depends on
having script2 and script3 loaded.

Re: [johnson-talk] Classes, prototypes, Ruby 1.9.x

At last test, Johnson isn't happy with any 1.9 branch. Threads and the JS GC don't work well together.

We're still not out of the woods with the unstable branch. While it
passes the johnson tests, it core dumps elsewhere.

My test right now is one of the specs in capybara -envjs:

smparkes@smp ~/capybara-envjs i386$ spec spec/driver/
envjs_driver_spec.rb

Classes, prototypes, Ruby 1.9.x

Hi,
Do you happen to have an example of how to define a class (or
rather a function/prototype) in JavaScript (e.g. Ruby.Person
or whatever) _and_ use that as a class in Ruby?
As a side note: There was an example in the RubyConf talk (2008)
about adding a method to a Ruby class from JavaScript context

Re: [johnson-talk] Browse a mutable tree

2010-07-20T01:07:24Z

Dear Johnson developers and users,
it is me again. I think last time my explanation was a bit confusing
and I
think my question simply goes down to the title. The mutable tree is
not
a real tree structure. Therefore, is there a way to browse it?
Obviously,
using the each iterator...
However, if I want to start browsing from a given node or leaf? How do

Re: [johnson-talk] Backtraces

2010-07-05T00:10:17Z

This is actually more an envjs issue than a Johnson issue. Johnson provides enough hooks to pass a string that SpiderMonkey will use in backtraces, it's just not hooked up in envjs for cases where the source is a URI (even a file URI, I think).
Could you submit an issue at [link] I can probably hack something into the current Johnson port and it's probably something that should go into the envjs platform API going forward ...

Re: [johnson-talk] Sandboxing and untrusted code

2010-07-05T00:06:23Z

Sandboxing would be nice, but I for one really don't know if it's possible. It would take time just to try to detect/plug holes, and I'm not sure there wouldn't be show stoppers.
As to your eval example, you'd either have to have no Ruby objects reachable from the untrusted JS, or, perhaps, make sure they were very restricted a la blank_slate. So restricted, in fact, I wonder if they'd be useful at all ...

Sandboxing and untrusted code

2010-06-27T11:16:55Z

Is it possible to run untrusted code inside of Johnson. I've removed
Ruby object (Ruby = null) inside of context, but It seems that you can
eval ruby code through RubyLandProxy object. You can replicate this by
running:

js = Johnson::Runtime.new()
js[:proxy] = {:key => 'value'}
js[:Ruby] = nil

Backtraces

2010-07-04T03:36:56Z

The lack of information when Johnson spits out a backtrace is
completely maddening:

Johnson::Error in 'Feature: Gift this (under Javascript) Scenario:
Choosing to gift items and going forward'
b is null
/Library/Ruby/Gems/1.8/gems/en vjs-0.3.6/lib/envjs/static.js: 1218

Thanks Steven, I will look that. I will let you know about my results.
