I completely forgot the paths that I need to setup to use open-uri in  
IronRuby when using with C#. I need to put those paths in my App.config  
to work with open-uri. Can anyone please paste those sections here? I  
keep forgetting those sections that I need to include in my App.config.

</div>

So, I added the paths that you provided in my C# code since I am trying  
to execute the .rb file from C#. Here is the complete code:

static void Main(string[] args)  
{  
var url = “[http://www.google.com.com](http://www.google.com.com)”;

```
        var engine = IronRuby.Ruby.CreateEngine();
        var scope = engine.ExecuteFile("../../screenscraper.rb");

        var paths = new List<String>();
        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib");
        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib\ruby\site_ruby\1.8");
        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib\ruby\site_ruby");
        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib\ruby\1.8");

        engine.SetSearchPaths(paths);

        var obj = 

```

engine.Runtime.Globals.GetVariable(“ScreenScraper”);

```
        var screenScraper = engine.Operations.CreateInstance(obj);

        var html = engine.Operations.InvokeMember(screenScraper, 

```

“scrape”, url);

```
        Console.WriteLine(html);

    }

```

When I run the application I get the following error:

Is this still an issue?

Provide a config file like this:

\<?xml version='1.0' encoding='UTF-8'?\> 

\<microsoft.scripting\>

```
<options>
  <set language='Ruby' option='LibraryPaths'

```

value=‘C:\ironruby\lib\IronRuby;C:\ironruby\lib\ruby\site\_ruby\1.8;C:\ironruby\lib\ruby\site\_ruby;C:\ironruby\lib\ruby\1.8’/\>  
  
\</microsoft.scripting\>

Host IronRuby like this:

var setup = ScriptRuntimeSetup.ReadConfiguration();  
scriptRuntime = Ruby.CreateRuntime(setup);  
Engine = Ruby.GetEngine(Runtime);  
Context = Ruby.GetExecutionContext(Engine);  
// You can use Context.Loader.SetLoadPaths(IEnumerable paths) to  
replace the load paths at run-time

you might want to move the executefile method

var url = “[http://www.google.com.com](http://www.google.com.com)”;

```
       var engine = IronRuby.Ruby.CreateEngine();

       var paths = new List<String>();

Here is my implementation:

static void Main(string args)  
{  
var url = “[http://www.google.com](http://www.google.com)”;

```
        var engine = IronRuby.Ruby.CreateEngine();

        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib\ruby\site_ruby");
        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib\ruby\1.8");

        engine.SetSearchPaths(paths);

        engine.ExecuteFile("../../screenscraper.rb");
        var obj = 

```

engine.Runtime.Globals.GetVariable(“ScreenScraper”);

```
        var screenScraper = engine.Operations.CreateInstance(obj);

        var html = engine.Operations.InvokeMember(screenScraper, 

```

“scrape”, url);

```
        Console.WriteLine(html);

    }

```

And now it throws the following error:

here’s an idea maybe buy my book. All this is explained in there

replace: paths.Add(@“C:\DevTools\ironruby-1.0-rc1\lib”);  
with: paths.Add(@“C:\DevTools\ironruby-1.0-rc1\lib\ironruby”);

That’s the location that contains stringio.rb.

It was like this when I sent the email earlier:

I copied the ironruby config file into my application’s config file and  
removed all the path variables from my application but it did not work.  
Then I added the “C:\devtools\ironruby-1.0-rc1\lib\ironruby” path and  
removed the app.config and then it worked out.

Any ideas that why even copy pasting the app.config from ironruby to my  
application app.config did not work?

I will definitely buy your book when IronRuby is publicly released! I  
don’t want to consult the book and find out that opps that has now  
changed in the final release.

a)IronRuby is in the home stretch.  
b)Ivan’s book is keeping up with the development, and if you buy the  
Manning EAP beta, you will get the updates and have the option to get  
the final copy.

You need to include the rest of the ironruby search paths. For example.  
“C:\devtools\ironruby-1.0-rc1\lib\ironruby”

Also, the ir.exe.config from c:\devtools\ironruby-1.0-rc1\bin should be  
setup exactly like you want. If you provide that to your app it should  
just work. That’s why we install that config file.

Probably because your app config is in a different location than ir.exe.

Try this. Replace:

static void Main(string[] args)  
{  
var url = “[http://www.google.com](http://www.google.com)”;

```
        var engine = IronRuby.Ruby.CreateEngine();

        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib\ruby\site_ruby");
        paths.Add(@"C:\DevTools\ironruby-1.0-rc1\lib\ruby\1.8");

        engine.SetSearchPaths(paths);

        engine.ExecuteFile("../../screenscraper.rb");
        var obj =

```

engine.Runtime.Globals.GetVariable(“ScreenScraper”);

```
        var screenScraper = engine.Operations.CreateInstance(obj);

        var html = engine.Operations.InvokeMember(screenScraper,

```

“scrape”, url);

```
        Console.WriteLine(html);

    }

```

With:

static void Main(string[] args)  
{  
var url = “[http://www.google.com](http://www.google.com)”;  
var setup = ScriptRuntimeSetup.ReadConfiguration();  
var scriptRuntime = Ruby.CreateRuntime(setup);  
var engine = Ruby.GetEngine(Runtime);  
//the following line might not be needed in this case  
var context = Ruby.GetExecutionContext(Engine);

```
        engine.ExecuteFile("../../screenscraper.rb");
        var obj =

```

engine.Runtime.Globals.GetVariable(“ScreenScraper”);

```
        var screenScraper = engine.Operations.CreateInstance(obj);

        var html = engine.Operations.InvokeMember(screenScraper,

```

“scrape”, url);

```
        Console.WriteLine(html);

    }

Is app.config in the same directory as c:\path\to\ir.exe? I’m guessing  
no. I’m NOT saying it should be. I’m saying use the other hosting method  
I told you to. I believe that will use IronRuby’s exe.config for  
IronRuby. If you don’t want to use my suggestion, then you need to  
modify the relative paths in your app.config to point to the right  
location.

Hi,

> > Probably because your app config is in a different location than ir.exe.

Do you mean the ironruby app config or my application app config? My  
application config is in my application directory. The question is that  
why it is not reading my application config automatically.

Thanks,  
Azam

I used the above code that you provided but it is throwing exceptions:

static void Main(string args)  
{  
var setup = ScriptRuntimeSetup.ReadConfiguration();

```
        var runtime = Ruby.CreateRuntime(setup); // error is thrown 

```

here  
var engine = Ruby.GetEngine(runtime);

And the exception is:

My fault I did not include the App.config settings. So, now I have  
copied everything from ir.exe.config into my App.config and I run the  
application and get the following error:
