Hi Guys!
I'm working on a project that involves some other developing language
then c#. It as some syntax, those reduces code development complexty
and gives more readability to code.

I would like to extend such syntaxes into C# but i dont know where to
start and how to do.

Many of you might have worked on such developments or might have used
custom syntaxes in different ways. I welcome your suggestions,
guidelines to put my thought in place.

Please provide some kick start info.

Thanks,
 
I thought there would be some replies by now.
Seems the content was not enough to attract attention.

here some more,

I'm thinking to develop some syntaxes like this:

if(item not in itemes)
{

}


if(item in items)
{

}

It would be nice to have some syntaxes those provides more readability
and less coding efforts.

if some one can give me a startup, it would be great.

Regards,
 
If items is a List it probably has the Contains function.
If it does, you can use
if(!items.Contains(item))
and
if (item.Contains(item))

Do you want to create your own compiler which has some similarities to C#,
but is tweeked with your own syntax specifications?

Do you want to build a preprocessor that converts the code you posted to
something like Ciaran posted, then just compile the temporary info as C#?

There are no compile-time metaprogramming capabilities available in C#
as of today. It is not clear when (or even if) they might appear.

If you want to extend C# for your own purposes, the best you can do is
take Mono C# compiler (which is, I believe, LGPL'ed), and hack its
source code to add the constructs that you want.

Alternatively, think whether your language extensions aren't actually
better off as library extensions.

See, that's precisely what I mean by "consider library solutions".

What's wrong with:

if (items.Contains(item))

?

Note that you can add this sort of functionality for any existing type
that "items" might have using extension methods in C# 3.0.

Also have a look at lambdas. They allow to define control structures,
though not quite with the same look as built-in ones. For example,
here's the parallelized foreach from Parallel LINQ:

Parallel.ForEach(items, item => {
Console.WriteLine(item);
});
