Hi,
The following crashes ruby on machine. If I don't use a context referencing self it works fine.
Thanks
Brendan
require 'v8'
gem "therubyracer", :require => 'v8'
class Window
def initialize
@ctx = V8::Context.new(:with => self)
end
def eval
@ctx.eval('7*8')
end
end
puts Window.new.eval

I just saw this on GH: https://github.com/cowboyd/therubyracer/issues/238 and that made me thing that perhaps having the Context initialized in the initializer itself is the problem. Sure enough:
require 'v8'
# or if using bundler (as with Rails), add the following to your Gemfile
gem "therubyracer", :require => 'v8'
class Window
def initialize
# @ctx = V8::Context.new(:with => self)
end
def eval
ctx.eval('7*8')
end
def ctx
@ctx ||= V8::Context.new(:with => self)
end
end
puts Window.new.eval
=> 56
