Ironruby core - Mar 2008 - Few Small Examples in Linq with IronRuby

Hello,

I know that its too early to ask or it.

But can someone provide few examples, how Linq with IronRuby will look
alike.

Since i am reading few books on LINQ in C#, i want to gradually try to
understand it with IronRuby point of view.

I do not want examples to play around. I want examples to understand
LINQ with IronRuby.

I hope someone might help me here.

Ho Ivan,

Thanks for pointing me a link. But the link is obsolete now.

------------------------------------------------------------
Translating this example: 
http://msdn2.microsoft.com/en-us/library/bb397947.aspx, it will look 
something like this:

require ''System.Core''
numbers = [5, 10, 8, 3, 6, 12]
numbers.where { |num| num % 2 == 0 }.order_by { |n| n }.each { |i| 
write("#{i} ") }

- John
--------------------------------------------------------------

I could see the example in Ruby, but the actual msdn2 link is now 
obsolete and the code is removed.

So i am unable to make any comparison.

Remove the comma from the URI.

Thanks John.

I did not notice that little comma. I just clicked the link.

Here''s the C# Code.

----------------------
class QueryVMethodSyntax
{
    static void Main()
    {
        int[] numbers = { 5, 10, 8, 3, 6, 12};

        //Query syntax:
        IEnumerable<int> numQuery1             from num in numbers
            where num % 2 == 0
            orderby num
            select num;

        //Method syntax:
        IEnumerable<int> numQuery2 = numbers.Where(num => num % 2 == 
0).OrderBy(n => n);

        foreach (int i in numQuery1)
        {
            Console.Write(i + " ");
        }
        Console.WriteLine(System.Environment.NewLine);
        foreach (int i in numQuery2)
        {
            Console.Write(i + " ");
        }

        // Keep the console open in debug mode.
        Console.WriteLine(System.Environment.NewLine);
        Console.WriteLine("Press any key to exit");
        Console.ReadKey();
    }
}
/*
    Output:
    6 8 10 12
    6 8 10 12
 */

With IronRuby, LINQ would be a fun.

Hope to see such more examples soon.

Thanks

Sorry for my more questions on LINQ.

I just read in LinQ in Action...it goes like this...

In chapter 2, we?ll show you the details of how the programming 
languages
have been extended to support LINQ. In chapter 3, you?ll learn how to 
write LINQ
queries. This is where you?ll learn about query operators, query 
expressions, and
expression trees. But you still have a few things to discover before 
getting there.

what i understand is... C# and Vb.Net have been extended to meet the 
LINQ requirement. So now we have C# 3.0 and Vb2008 right.

My question is ... what about Ruby 1.8 or 1.9...? are they already 
capable with their inbuilt features to support LINQ or IronRuby shall 
incorporate those extra additions to meet the LINQ requirement....?

How far in IronRby from LINQ now...?

Thanks

I am the second interested.

LINQ 2 SQL is very important. I think few experts should start some 
tutorials about this

Looking at the codes in C# and Vb.Net does not make any sense, as we are 
never going that way.

IronRuby + LINQ is the way many like me would go.

I think, its time for some experts to come ahead a start blogging about 
Linq to sql with Iron Ruby to start with.

+ 1 on the suggestion by Mr.Rahil
