Fluent Interfaces: How Far is Too Far?

panesofglass — Fri, 07 Aug 2009 15:12:01 +0000

Humor me a moment. I know I’ve promised a series on REST/HTTP/HTML that will likely drive everyone nuts, but I had a thought this morning that is probably more bizarre than many others I’ve had. I have really enjoyed building and using fluent interfaces for tools I’m using. I think they can make the code both more readable and maintainable, though the approach differs from more traditional approaches. I’ve recently been working on a fluent interface for creating Atom items and feeds using the System.ServiceModel.Syndication namespace, and that has been both frustrating and fun.

This morning, however, I had the thought of creating a fluent interface for one of the most simple of concepts used in .NET: collections. What’s wrong with collections you ask? Nothing really. But what if instead of reading

collection.Add(item)

you could read

Add.the(item).to(collection)

? Which is more readable? In the end, that’s similar to what I’m doing with the System.ServiceModel.Syndication bit, except that you don’t generally just add one or a few things to the collection in the syndication example. We could create something similar to add and remove events, all using a single static Add/Remove class with various, overloaded methods for the common identification operations.

Is this overkill? As JB mentioned to me over IM, it’s relative. For some, I’m sure you will think I’m nuts. Others may think I am on to something. I don’t think I would go and do it for no reason at all, but if I ended up with some crazy list creation or end-user-wants-to-read-my-code scenarios, I might consider something like that. What do you think?

Tutorial D in F#

Does anyone know of a project to implement Tutorial D in F#, similar to the Dee project for Python? I’m currently trying to get Dee working on IronPython, which would get me closer to my goal of using a true relational model for data access. I would like to stick with a .NET implementation, so that leaves out Rel. I have tried Dataphor, but I find it trying to be too much a complete platform and not easy to use as just a utility. I think either a good C# or F# implementation would be both excellent to have and a fun project on which to work. Anyone interested?

Anders Hejlsberg on the Future of C# (PDC 2008)

panesofglass — Wed, 29 Oct 2008 15:20:44 +0000

In case you are missing PDC like me, you can find some great videos of the sessions on Channel 9. I found Anders’ comments on the future of C# to be incredibly exciting. You can watch it here. I’d love to hear feedback on whether you to are excited about the new features he points out for C# 4.0:

Dynamically Typed Objects
Optional and Named Parameters
Improved COM Interoperability
Co- and Contra-variance

Update: You can now download and try out the CTP for Visual Studio 2010 and the .NET Framework 4.0 from Microsoft Connect!
