I have updated my Crimson framework to use PHP 5.3 namespace support instead of the old PEAR style class namespacing. I did this primarily as an exercise in migrating a code-base to use namespaces. Just in case anyone was relying on the old framework code, there is a pre-5.3 branch on github.
Along the way I decided to deviate from the separate component structure and merge all components into a single framework structure. It is still my goal to keep dependencies within the framework to a minimum, but I felt the extra work required to maintain each component separately was not worth it. This was especially the case for the unit tests. Each component required a considerable amount of boilerplate code to bootstrap and run the tests. I was able to reduce the amount of boilerplate considerably by merging the tests into one suite. I have been following the developments of Zend Framework 2.0 to see what major changes they are making. I think the large overhaul to the ZF2 tests section was a significant influence on my decision to do some overhaul myself.
I have also added some additional features to the framework that I will be talking about in a later post.
