Hi,
I am doing this to implement a DSL. I want to allow user to define some
function and be used by the DSL. Without this, I don't know how to get
it working. I am sure there is a rational explanation for what I see.
Could someone help me please?
Thanks,
Lewis

Hi,
Thanks for the reply. My main development version is on 1.1 for .NET
3.5. However, I did try it on 1.1.3 on .NET 4.0.30319.225 and still
are able to reproduce the issue. I am running Windows XP 32bit
environment. Is there any environment variables I should look into?
Here is the screen copy I just did.
As far as I understand, the global environment is actually a 'main'
Object. The function defined in the global scope should be translated
to private method of Object class which is what it shows in iirb.bat.
Not sure why ir.exe as well as the ScriptEngine behaves differently.
Thanks for your time!

It works as expected: ir.exe result is same as irb result.

*Subject:* [Ironruby-core] Access Top Level methods
Hi,
I am trying to access top level method from the class definition in
IronRuby scripts. Example:
def global_hi
end
class A
def hi
global_hi
end
end
A.new.hi
The script executed in ScriptEngine throws a NoSuchMethodError.
I tried to ran the same code in iirb.exe It seems to behave the way I
expected. But when I tried it in ir.exe, it throws the exception as well.
I investigate a little more and found out
irb(main):021:0> self.method(:global_hi)
=> #<Method: Object#global_hi>
and
in ir.exe as well as script engine
>>> self.method(:xx)
=> #<Method: Object(#<Class:#<Object:0x0000058>>)#xx>
Is there anyway to make the script behave like the one in iirb.exe?
Thanks,
Lewis
