Calling ruby scripts from C#

skyrebel · September 30, 2009, 3:17pm

Dear users,

I want to build a testscript scheduler / executer in C# that runs
several Ruby scripts in sequence.

For this I use IronRuby with the following constuction:

ScriptRuntime runtime = Ruby.CreateRuntime();
ScriptEngine engine = runtime.GetEngine(“rb”);

loop through scripts:
engine.ExecuteFile(“script.rb”);

This works fine for basic scripts. However some scripts have class
definition that inherite from a base class.
When such a script (class < baseclass) is passed in:
engine.ExecuteFile(“script.rb”);

The following exception is thrown:
Microsoft.Dynamic
uninitialized constant Object::BaseClass

I can not find a solution for this problem, so any suggestion is
welcome. If I need an other approuch, do hesitate to say so. Still
learning about Ruby integration in .NET

Thanks in advance

you have to require the other files it uses too in the same engine.
or you can add the paths to where the scripts can be found to the
$LOAD_PATHS ($:) variable.

require a file:

github.com

casualjim/ironrubymvc/blob/master/IronRubyMvc/Core/RubyEngine.cs#L279


      
          /// Gets the global variable.
          /// </summary>
          /// <typeparam name="T"></typeparam>
          /// <param name="name">The name.</param>
          /// <returns></returns>
          public object GetGlobalVariable(string name)
          {
              return Runtime.Globals.GetVariable<object>(name);
          }
          
          
/// <summary>
          /// Loads the assemblies.
          /// </summary>
          /// <param name="assemblies">The assemblies.</param>
          public void LoadAssemblies(params Type[] assemblies)
          {
              assemblies.ForEach(type => LoadAssembly(type.Assembly));
          }
          
          
/// <summary>
          /// Requires the ruby file.

add load paths

github.com

casualjim/ironrubymvc/blob/master/IronRubyMvc/Core/RubyEngine.cs#L346


      
              ContractUtils.RequiresNotNull(engine, "engine");
              var context = Microsoft.Scripting.Hosting.Providers.HostingHelpers.GetLanguageContext(engine) as RubyContext;
              if (context == null)
              {
                  throw new InvalidOperationException("Given engine is not a Ruby engine");
              }
              return context;
          }
          
          
public static RubyContext GetExecutionContext(ScriptRuntime runtime)
          {
              ContractUtils.RequiresNotNull(runtime, "runtime");
              return GetExecutionContext(Ruby.GetEngine(runtime));
          }
          
          
private void Initialize()
          {
              Engine = Ruby.GetEngine(Runtime);
              Context = GetExecutionContext(Engine);
              CurrentScope = Engine.CreateScope();
              Operations = Engine.CreateOperations();

Thanks! The require a file (containing the base) option works.

But adding the path to the file containing the base class does not. Here
C# reports an error that the file can not be found. Don’t what’s wrong
here, but for know the require a file option will do the trick.

skyrebel · September 30, 2009, 5:41pm

root |_ lib
|_ great_class.rb
|_ test
|_ test_great_class.rb

let’s say I add root to my load path
then I can reach the files in lib with require ‘lib/great_class’

or in test_great_class.rb you can do
require File.dirname(FILE) + “/…/lib/great_class”

you are free to add the extension in case you’re using require.

In our application, we also found we found ‘load’ useful in some
circumstances to force reloading of script files, since ‘require’ will
not
reload files it knows it’s already loaded.

If the base class is defined in file “foo.rb” and used in file “bar.rb”
this should also work:

engine.ExecuteFile(“foo.rb”);
engine.ExecuteFile(“bar.rb”);

Example:

C:\Temp>type foo.rb
class C
end
C:\Temp>type bar.rb
class D < C
end
p D.ancestors

C:\Temp>rbd

Agreed. We found if we changed the definition of class C, unless we did
something like ‘load’, it would continue to use the old definition from
the first load.

Kernel#load is very similar to ExecuteFile, so you can use either for
bringing the definition up to date.

Apologies if my earlier answer was rude. I wasnâ€™t trying to be rude, and
looking at it I realize it could be taken as such. I know I appreciate
hearing that people are using IronRuby on real projects, not just as a
novelty language â˜º

Agreed. We found if we changed the definition of class C, unless we did
something like ‘load’, it would continue to use the old definition from
the first load.

Re: [Ironruby-core] calling ruby scripts from C#

If the base class is defined in file â€œfoo.rbâ€ and used in file â€œbar.rbâ€
this should also work:

engine.ExecuteFile(â€œfoo.rbâ€);
engine.ExecuteFile(â€œbar.rbâ€);

Example:

C:\Temp>type foo.rb
class C
end
C:\Temp>type bar.rb
class D < C
end
p D.ancestors

C:\Temp>rbd
IronRuby 0.9.1.0 on .NET 2.0.50727.4918

engine = IronRuby.create_engine
=> Microsoft.Scripting.Hosting.ScriptEngine
engine.execute_file(“foo.rb”)
=> Microsoft.Scripting.Hosting.ScriptScope
engine.execute_file(“bar.rb”)
[D, C, Object, Kernel]
=> Microsoft.Scripting.Hosting.ScriptScope

Re: [Ironruby-core] calling ruby scripts from C#

root
|_ lib
|_ great_class.rb
|_ test
|_ test_great_class.rb

let’s say I add root to my load path
then I can reach the files in lib with require ‘lib/great_class’

or in test_great_class.rb you can do
require File.dirname(FILE) + “/…/lib/great_class”

you are free to add the extension in case you’re using require.

No worries, I didn’t read your comment as rude. I fully realize the
error
of my ways in not embracing Ruby earlier in my career.

It’s just an interesting thing to keep in mind with projects like
IronRuby, that people come to it with different backgrounds. It will be
interesting to see what sort of orientation documents are produced for
those coming to IronRuby from a .NET (C#/VB.NET) background. I foresee
articles like these from the days when C# was young:

C++ → C#: What You Need to Know to Move from C++ to C#

C# From a Java Developer’s Perspective

Re: [Ironruby-core] calling ruby scripts from C#

Apologies if my earlier answer was rude. I wasnâ€™t trying to be rude, and
looking at it I realize it could be taken as such. I know I appreciate
hearing that people are using IronRuby on real projects, not just as a
novelty language J

the info I can get and will most probably be back with futher questions.

Calling ruby scripts from C#

But adding the path to the file containing the base class does not. Here C# reports an error that the file can not be found. Don’t what’s wrong here, but for know the require a file option will do the trick.
