Subject: [Ironruby-core] ScriptRuntime.Operations.CreateInstance() is very
	slow
Message-ID: <CAOKgAd48xi2S=gDz85T8_7WwSE+o30mpdnm8avKgrCdp5xz0sg@mail.gmail.com>

Hi all,

I use IronRuby as a scripting environment inside my c# app.
I have to create instances of ruby objects inside c# code, and I'm doing it
with ScriptRuntime.Operations.CreateInstance(). It's the largest
performance bottleneck in my app currently.
Is there any workaround? Will it be faster, if I create ruby functions
which instantiate my objects, and call these function instead
of ScriptRuntime.Operations.CreateInstance()?

The ruby classes are subclasses of my clr classes.

Thanks,
Anton

Subject: [Ironruby-core] Problem with using OpenStruct and ERB
Message-ID: <BAY152-ds130BA8FEDEE1748BA2A110AEFF0@phx.gbl>

I am using OpenStructs and ERB for template generation. In this simple
example, ruby 1.8.6 runs this fine:

require "erb"

require "ostruct"

puts ERB.new("<%=foo%>", 0, "%<>").result(OpenStruct.new({ :foo => "bar"
}).send(:binding))

 

However, it generates the following error when I run this in IronRuby
1.1.3.0 on .NET 4.0.30319.269:

(erb):2: undefined method `foo' for main:Object (NoMethodError)

 

Does anyone know how to get this to behave correctly in IronRuby?

I notice that in your example, you don't declare the local variable foo 
anywhere:
If I run it verbatim, both MRI and IronRuby fail with undefined method foo 
(and fair enough, foo isn't defined).
When I declare foo as a local variable, both MRI and IronRuby work fine 
for me.

Ahh I see.

I don't have a copy of 1.8.6 handy to test on, but this definitely fails 
for MRI 1.9. 
It seems like getting the binding of an ostruct in 1.9 doesn't work for 
evaluating local variables. Perhaps they changed ostruct?

Here's what happens for me:

irb(main):020:0> ostruct = OpenStruct.new({:foo => 'bar'})
=> #<OpenStruct foo="bar">
irb(main):021:0> ostruct_binding = ostruct.send(:binding)
=> #<Binding:0x2545dd0>
irb(main):022:0> eval("foo", ostruct_binding)
NameError: undefined local variable or method `foo' for main:Object

IronRuby 1.1 aims for compatibility with ruby 1.9 (and ships standard 
libraries such as ostruct from 1.9 also), so it is designed to fail with 
the same errors as MRI 1.9

I'm not sure what you can do to work around it, all the best.

Yeah, that seems like it was the problem. I fixed it by defining the getter
method directly in the object I was running the ERB file in. 

require "erb"
def eval_field(field)
  field.each do |key, value|
    class << self; self; end.class_eval do
      define_method(key) { @field[key] }
    end
  end
  @field = field
  binding
end

ERB.new("<%= foo %>").result(eval_field({:foo => "bar"})

I find it odd that OpenStruct won't work, despite this code almost being
almost identical to that of OpenStruct.
