An Tour of the STL.NET

Nice intro article, Stan. Thanks for it - was quite useful for me specially since I've never used STL before :-)

I found the different naming style a little funny though - all the STL functions start with a small letter :-) But then I guess you had to retain that style for making it as similar to normal STL as possible.

well, you're becomming a veritable one person fan club -- but thank you. the naming conventions of the stl illustrate their historical roots in a non-object-oriented universe (in fact, alex is somewhat passionate in his dislike of OO programming) in which isA was is_a, and StringBuilder was strb -- ah, for the good old days ... wasn't that a time :-)

Thanks for interesting article!

I've noticed that in the article both the System::Collections and System::Collections::Generic examples use "using namespace", while in STL.NET example the namespaces not even mentioned. Does it mean that STL.NET classes live in global namespace?

Was the misspelling of "Veritible" intended? Is there a pun somewhere later in the article on this?

At last, STL for .Net!

I think the naming convention problem could be a show stopper. The naming convention of the STL would clash too heavily with .Net strict rules (I can hear FxCop scream).

I'm really missing the concepts of iterators (IEnumerator is cool but not sufficient).

A while ago, I also gave a shoot at doing some STL-ish things in .Net 2.0 ( http://blog.dotnetwiki.org/archive/2004/08/10/752.aspx ).

Also, do you think "template" intensive such as Spirit,uBlas or boost could be ported to .Net ?

show stopper sounds rather severe -- i wonder if you could elaborate on that? keep in mind that templates are internal to an assembly, and that we interface with the public through ICollection, IList, and IEnumerator. If you are missing the concept of iterators, blame me not yourself. I will over time post an article on them, and hopefully that will help get you over the conceptual bridge. i don't know the `modern' template libraries such as boost, except by reputation -- anso tsao, a colleague here at microsoft, could better speak to that.

Sorry, in fact "show stopper" is rather severe. Let me elaborate.

.Net comes with a rather strict and complete naming guidelines ( http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpgenref/html/cpconpropertynamingguidelines.asp ) which can be enforced with tools such as FxCop (developpped by Microsoft).

Among the numerous guidelines, the most important (to me) are:

- class names, public and protected methods, public properties, public fields should be capitalized,
- private fields and method parameters should be CamelCase

Therefore, STL does not follow such guidelines (of course, STL existed long beforfe .Net).

I'm not blaming you for "missing the concept of iterators", in fact I'm thanking you for getting STL back into .Net.

Cheers,
Jonathan

thank you, jonathan. but many people other than myself deserve the credit for getting the STL back into .NET: Anson Tsao, Martyn Lovell, in particular, and P.J.Plauger, as well as others. In this case, I'm really just another enthusiast.

again, with regard the naming conventions -- 1. as i suggested in my previous comment, templates are internal to an assembly and in that sense are exempt, i think, and 2. as you point out, their naming decisions `grandfather' these guidelines.

thanks for getting back.

One blunder i made in the article was to not realize that List<T> is the Generic analog to (a) ArrayList, and (b) Vector. i just skimmed through the documentation a bit too fast, and it didn't register on me that List<T> could be used as the name of a capacity-based vector. so, the second example of a generic container should be List<T>, not Collection<T> ... List has a full interface ... and so on. My bad ...
