Hi,
I need to visit the members of a C++ type using Fusion sequences. For structures I plan to use BOOST_FUSION_ADAPT_STRUCT. I need also to visit also c-arrays (with static size). I see that there is already an adapter for boost::array. Is there an adapter for C-arrays?
Sorry, no. Would you want to contribute one? It's easy if you take a look at the boost::array adapter.
Hi,
Well if doesn't exists I will need to see how to do it :) I will inform you when I reach to get something.
I just added an implementation for adapting plain arrays to the c++0x branch of fusion. You can find the code here:
https://svn.boost.org/trac/boost/browser/sandbox/SOC/2009/fusion/boost/fusio... https://svn.boost.org/trac/boost/browser/sandbox/SOC/2009/fusion/boost/fusio...

Is there a simple way to implement this flat view? Or even better, is it already available?
It is. Check the (undocumented) code in the ext_-directories.
https://svn.boost.org/trac/boost/browser/trunk/boost/fusion/container/ext_/t... https://svn.boost.org/trac/boost/browser/trunk/boost/fusion/algorithm/iterat...
Unfortunately the code is pretty much broken at the moment.

Hi, thanks for all these pointers. I was starting to implement it,when DING, your post appeared. I'm sure I would made a lot of errors before reaching to run the test. Do you know if it is planned to document the tree extension soon? Is there any post about this subject? Just a remark most of the .hpp files on po_array are not self contained as the structure po_array_tag is not declared in th file. Thanks again, Vicente
