Hi all, I'm wondering if we could make efforts to refactor code modules in the cctbx_project so as making it have the minimum number of dependencies. This would be helpful to other users of the CCTBX that wishes to develop code on top of it. In the longer term it would also make it easier for us to deploy CCTBX as a Python wheel installer and by implication, spread the gospel of the wonders of the CCTBX. What is currently complicating this is the inclusion of the dxtbx module within the cctbx_project. It is being used by Dials. So my question is if it would be possible to move this project into the Dials code? If the dxtbx was just another small module it wouldn't be much of a problem. But the dxtbx depends on the cbflib and HDF5 components. If you want to build CCTBX from sources that's cumbersome. Why? Because CCTBX as deployed from CCI on http://cci.lbl.gov/cctbx_build/ is only built for a few select platforms. Building CCTBX on a different platform from those with bootstrap compels us to also build cbflib and HDF5 from scratch. Although this is not impossible it does increase the entry barrier for other potential users of the CCTBX who wish to incorporate the CCTBX in their programs: If all a user wants is to calculate allowed origins and symmetry sites for a given space group then an alternative to CCTBX might be preferable rather than having to massively expand their project with the seemingly unrelated HDF5 component. In other words, as it stands now the CCTBX is not straightforward for others to adopt. What do other people think?
