Lets say you have a compile type defined type, like a tuple or a fusion sequence. And its easy to access, just call get<Index>(variable) and you get the reference to the types run time instance in the index. Easy. But for this you need to know which index to call at compile time. What if you get that index only at runtime? Like in the previously mentioned Model/View Interface of Qt?

A short blog post on 3 little functions I've written with mp11, to show a bit more how one can work with mp11. The first two are related to working with tags, the last is an easy way to get the member names of a fusion adpated struct into an std::array.

Yesterday and today I did some fun coding to play around with boosts new, C++11 TMP library: mp11. I have an idea, and one of the fundamental building blocks would be boost::fusion and its adapt struct infrastructure. I wanted to know if I could combine fusion and mp11 in a good way, to create a certain interface. I'll likely go into the exact ideas and reasoning for this interface later, for now lets focus on how to create it.

Yesterday I had the pleasure to implement a new feature in my CMS: moving a page or directory with in the website tree. Its quite easy, once you've implemented it, but it was also an interesting exercise in using code I once wrote. In Summer of 2015 I wrote this tree implementation, this old blog post also covers most of the interfaces which I needed to use now.More Blog entries
