Re: [Ironruby-core] Problem with using OpenStruct and ERB

2012-06-22 Thread Nathan Standiford 
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.

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.

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.

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?
