I've got the crystallography features nearly completed in Avogadro 2 in my spg branch on Github (https://github.com/AlbertDeFusco/avogadrolibs/tree/spg
) and I just wanted to give you guys an update on what I've been up to.
Below are menu entries for the features that I have working. Each new feature in the Crystal and Build menus is available through Avogadro::Core::CrystalTools. The qtplugins just pass pointers to molecules and unitcells around. I will probably add a command line tool in the near future for many of these features.
The "Set Space Group" dialog is not yet completed. I have the back-end routines, but I haven't gotten the UI finished. I'm using this CrystalMaker snapshot as a guide (http://avogadro.cc/wiki/CrystalMaker
). There are some tricky things with QColumnView I haven't worked out yet. If you guys have an example I can work from that would be greatly appreciated.
As in Avogadro1 many of the crystallography features require spglib. For now I have just copied the full spglib repo into the avogadrolibs/thirdparty directory and soft-linked it into avogadrolibs/avogadro/core directory so I can get it to build easily for me. Do you guys have a tutorial for using the CMake thirdparty features? I wasn't able to make much use of it at the moment.
