Hi,
I am trying to create a Dsl which will have instances that live in
individual Dsl .rb files and then run them from the CLR.
I want to create and set the values of the Clr object in IronRuby and
then somehow have access to the CLR object after the .rb Dsl instance
file has run.
Here is my Clr object which is very simple at the moment:
namespace Horn.Core.Dsl
{
public class BuildMetaData : IBuildMetaData
{
public string Description { get; set; }
}
}
I have the following module which I am using to specify my Dsl and which
will create an instance of the BuildMetaData specified above:
module MetaBuilder
module Dsl
module Main
attr_accessor :metadata
def install(name, &block)
@metadata = Horn::Core::Dsl::BuildMetaData.new
yield self if block_given?
end
def description(desc)
@metadata.Description = desc
end
def get_metadata
@metadata
end
end
end
end
include MetaBuilder::Dsl::Main
I somehow want to be able to get the @metadata property from the Clr
code after an instance of the Dsl has ran.
An instance of the Dsl looks like this currently:
install :horn do
description "A .NET build and dependency manager"
end
My C# code looks like this currently:
var engine = Ruby.CreateEngine();
engine.Runtime.LoadAssembly(typeof(BuildMetaData).Assembly);
engine.ExecuteFile(buildFile);
var klass = engine.Runtime.Globals.GetVariable("get_metadata");
Is there anyway I can get at the @metadata property without having to
pollute the Dsl instance?
For that matter is my approach reasonable or is there perhaps a better
way?
Thanks in advance
Paul
