[Vala] Fwd: Namespaces and Compiling With Multiple Source Files

[Landon Blake <sunburned surveyor gmail com>]

Jonas and Steven:

I feel quite stupid for making that mistake. You are correct, when I
executed the executable with out appending ".vala" everything ran
correctly.

I really appreciate the help and support from the Vala community so
far. The forum has been patient and responsive.

I hope to make some minor contributions back to the community soon.
This will include some code. I'm working on some unit testing classes
that imitate a testing framework I designed for Java. I've also
started on some collections classes (lists and trees). The collections
offer the user a bit of control over the internal operations of the
collection, and they operate on a Collectable interface which supplies
methods on comparison and equality, instead of using generics. I've
also got some basic geospatial geometry code I'll be able to split out
into a reusable library.

I hope I can start sharing this code in the next couple of weeks!

I'd also like to contribute some documentation. I'm using Vala to
develop a library for the management and production of cartographic
annotations. The development of this library is going to be featured
in a new series of articles in the OSGeo Journal
(http://www.osgeo.org/journal). My documentation efforts will start
there. My first article should appear in the issue of the journal
being published before the end of the month, so I will be sure to
share the link here.

Thanks again for all the help! I look forward to learning more about Vala!

Landon
