Ironruby core - May 2010 - How to transfer scriptscrope to a RubyCommandLine

I found Ironruby 1.0 change a lot for some APIs, at previous version

I can create a rubycommandline via C# like this

IronRuby.Hosting.RubyCommandLine rubycommandline = new
RubyCommandLine(new
IronRuby.Runtime.RubyContext(ScriptDomainManager.CurrentManager));

but now the construction accept zero parameters, so How transfer a
scriptscope to RubyCommandLine..?

I used debug to verbose the instance of RubyCommandLine, its scriptscope
is always null!

2nd question why global variable does not work?


Form frm = new Form();
ScriptEngine ruby = 
IronRuby.Ruby.GetEngine(IronRuby.Ruby.CreateRuntime());
ruby.Runtime.Globals.SetVariable("frm", frm);
ScriptScope scriptscope = ruby.Runtime.CreateScope();
ScriptSource script = 
this.scriptengine.CreateScriptSourceFromFile("test.rb");
scriptscope.SetVariable("frm",frm);
ruby.Execute(script.GetCode(),scriptscope);
-----------------------------------------------
test.rb

defined? $frm
---------but it is nil....
defied? frm
it is ok...

Ruby global variables are not accessible via hosting API.
ScriptRuntime.Globals refers to global constants (constants defined on Object).

ScriptEngine ruby = IronRuby.Ruby.CreateEngine();
ruby.Runtime.Globals.SetVariable("Bar", 2);
ScritpScope scope = ruby.CreateScope();
scope.SetVariable("frm", 123);
ruby.ExecuteFile("test.rb", file);

where test.rb is
p frm, defined?(frm), p Bar

prints
123
Nil
2

frm is looked up via method_missing on the main object.

Can you describe your scenario where you use the command line? What features you
need? It''s relatively easy to implement a command line yourself (see
e.g. http://blog.tomasm.net/2009/04/15/python-says-hello-to-ruby/). The APIs in
Microsoft.Hosting.Shell are mostly legacy and I wouldn''t recommend
using them.

I tried to store a WinForm in my script scope, and if i could transfer 
the script scope to the command line, that I have a chance to operate 
this WinForm in ruby console. As an example,I could change the title of 
the WinForm in command line like this:

$frm.text="hello,world"

seems in ironpython (refer to 
http://ludovic.chabant.com/devblog/2009/12/24/exposing-global-variables-in-ironpython/)

I can get the global variables via import something, but to ironruby 
whatever require or include, I can not import a global variables.

Hi, Tomas

Thanks a lot for your response.

Here is an interesting example I found, but after upgrade to Ir 1.0 
(.net 4) , it does not work now

Thanks

Thanks Tomas

At last, I found a thread you replied previously. if I used

            RubyContext context = GetExecutionContext(ruby);
            context.DefineGlobalVariable("logowin",logowin);

it works as expected.. this made me a little confused, is the

context.DefineGlobalVariable

the same as

ruby.Runtime.Globals.SetVariable

the naming is just similiar and drive me crazy..

Regards
Ray
