Hi Karsten, hi Beck. Just pushed stem support for extrainfo descriptors (ye gods they have a lot of attributes)...
* Implementation https://gitweb.torproject.org/stem.git/blob/HEAD:/stem/descriptor/extrainfo_...
* Unit Tests https://gitweb.torproject.org/stem.git/blob/HEAD:/test/unit/descriptor/extra...
* Integ Tests https://gitweb.torproject.org/stem.git/blob/HEAD:/test/integ/descriptor/extr...
Barring distractions I plan to next implement network status entities, then start porting over Onionoo. That said, between going oncall for work and the upcoming release of Diablo 3 it might be a little while. :P
