Forum: IronRuby Open-Uri Path in App.Config

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.

I guess you're talking about that:
<options>
  <set language='Ruby' option='LibraryPaths'
value='..\lib\IronRuby;..\lib\ruby\site_ruby\1.8;..\lib\ruby\site_ruby;..\lib\ruby\1.8'/>
</options>

Is this still an issue?

Provide a config file like this:

<?xml version='1.0' encoding='UTF-8'?>
<configuration>
  <configSections>
    <section name='microsoft.scripting' requirePermission='false'
type='Microsoft.Scripting.Hosting.Configuration.Section,

    </options>
  </microsoft.scripting>
</configuration>



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<string> paths) to
replace the load paths at run-time

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";

            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:

Here is my implementation:

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

            var engine = IronRuby.Ruby.CreateEngine();

            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);

            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:

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.

JD

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: <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'/>

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.

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";

            var engine = IronRuby.Ruby.CreateEngine();

            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);

            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";
            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);

        }

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

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.

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:


Unhandled Exception: System.ArgumentException: Invalid argument value
Parameter name: ScriptRuntimeSetup must have at least one LanguageSetup
   at Microsoft.Scripting.Hosting.ScriptRuntimeSetup.ToConfiguration()

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:

Did you change the paths in the app.config file to be absolute?

Ahh I did not do that!! I think I will just use path collection and 
List<String> this is just too much work.
