How to use linq.js with sharpkit

[Ramin Zarei]

Hi.

How to use  linq.js javascript library?

Can any one provide Extension for linq.js javascript library?

Thanks.

[Dan-el Khen]

This library support has not started yet, if you'd like I can open a new project in SVN for this library and give you write access to it, I will also be able to help you out if you have any issues. If not, feel free to post an 'enhancement' request in our issues list:

http://code.google.com/p/sharpkit/issues/list 

You can star the issue and get notified when it's implemented.

Cheers

Have you already tried the LINQ support inside CLR mode? It's not perfect, but may be sufficient.
As Dan-el noted, you can also roll your own (instructions at http://sharpkit.net/Wiki/Using_Web_Libraries.wiki ).

[Ramin Zarei]

Would you please provide me a sample with CLR mode linq, does it has groupby and where methods?

[Ramin Zarei]

Hi,

At the moment i'm very busy, however later i'll contact u.

Thanks. 

[Arithmomaniac]

Where, yes.
GroupBy, no.

[Ramin Zarei]

Thanks.

[Dan-el Khen]

Thanks Arithmomaniac!

In any case I have started a project in SVN to support linq.js:

http://code.google.com/p/sharpkit/source/browse/#svn%2Ftrunk%2FSharpKit.LinqJs

Hi, its my questions too.

Is it still under development?

I didn't understand how to use linqJS. I don't want use CLR mode too.

This library is already finished, I have added a few fixes right now, and a sample project, but it seems fine:

            var x = Enumerable.From(new JsArray<JsString>{"asdsad", "ASdsad"}).Where(t=>t.substr(0, 1)=="a").ToArray();

Didn't you have plan to add language extension for it?
Regards

[Dan-el Khen]

I'm not sure what you mean by language extension - but this library seem to work perfectly, so I'm not sure what is the need. Did you have anything specific in mind?

Dan-el

[Mohammad Nikravan]

I mean same as System.Linq. Add extension to JavaScript collection objects such as JsArray and JsObject

sample:

var s = new JsArray();

s.<show linq methods here>

Regards

[Dan-el Khen]

Yes, it's possible to add something like this:

var x = new JsArray();

x.AsLinqJsEnumerable().Where(...)

Would you like me to add this helper extension method?

Dan-el

[Mohammad Nikravan]

Would you like me to add this helper extension method?

Thanks you that ask from me, I think you are more expert to decide, but Why .AsLinqJsEnumerable?

C# automatically add Linq extension when the "using System.Linq" added to header.

Isn't possible to do same as C# so the method show on Collection without AsLinqJsEnumerable?

By the way I am not Linq veteran.

Regards

[Dan-el Khen]

The AsLinqJsEnumerable() method replaces the Enumerable.From() method, you have to call it, it's not an invisible method, I have simply provided a different calling style to the same function using extension methods. I have put this method under SharpKit.JavaScript namespace, so you won't have to add any other usings, only to reference LinqJs assembly.

Does that make sense to you?

Dan-el

[Mohammad Nikravan]

Looks good, maybe AsLingJs is enough.

Regards

[Dan-el Khen]

I have added: ToLinqJsEnumerable() - When I thought about it 'As' is not a good prefix for the method, since it's a real method invocation, and not some invisible casting. In any case, it shouldn't be so bad that it's a bit of a long method name - since Visual Studio already autocompletes the code anyway... :-)

Dan-el

[Mohammad Nikravan]

But I didn't understand why ToLinqJsEnumerable() is necessary while C# does need such method for System.Linq

Regards

[Dan-el Khen]

C# might not need this method, but LinqJs does require it. You can create a shortcut method to do it automatically if you want, but you should be aware that Enumerable.from() method must be invoked - either statically, or automatically, in order to convert your JsArray into a LinqJs compliant enumerable.
