Pymod package splitting

[thomaslima]

Refactored the pymod package so that the CPython extensions were renamed to *.core. For example, klayout.db is now klayout.dbcore. Then, I created klayout.db which imports all names from klayout.dbcore, and added the PCellDeclarationHelper, for example, which is present in pya.

I had to change the folder structure a little bit due to a setuptools bug pypa/setuptools#230

I also had to create an empty folder named db_plugins inside src/pymod/distutils_src/klayout so that python setup.py develop would function properly. Now the editable install, i.e. pip install -e . works.

Hi Thomas,

I have changed the version to .dev7 which is the next one available. Some conflicts I resolved (testing is yet to do).

Hi Thomas,

please consider merging b80ce12 into your pymod branch. I had to refactor (unify layout) the distutils_src directory to fix the qmake-based builds. Essentially tl.py git moved to tl/init.py. Same for rdb. Overall the solution is a good one as qmake-based pymod builds now use the same sources than the setup.py ones.

Thank,

Matthias

Sounds good. Nice work.
I am a bit confused though. Does it mean that normal qmake also builds pymod as well as setup.py? Is it supposed to build pymod because of the Qtbindings?

[klayoutmatthias]

No worries, nothing wrong :-) ... qmake-based Python modules were the first. They are still provided to supply the Python modules coming with the Debian and RPM packages. I see one more benefit: as they are integrated with the main application's build, they are part of the test suite. They basically share most of the source code with the setuptools-based distribution (again), so there is little overhead (except me having to maintain the qmake-builds and RPM/DEB packager scripts).

BTW: there are three more small patches, so maybe you may like to pull pymod's HEAD.

Thanks,

Matthias

Plus one more commit ... (Python 2 compatibility)

Thanks for letting me know. I am going to take a break from maintaining travis builds. It seems they're going through some changes now and every time I have to change the travis script. This instability is killing me. When pymod gets merged to master I'll try to work on CD to pypi.
