HoloViews: Port Request

[nhchan]

​HoloViews is a powerful visualisation package for python that works with matplotlib, bokeh, pandas, seaborn, etc.

It requires numpy and param(​https://param.pyviz.org). The former is already on MacPorts, but I am unsure about the latter.

Currently, holoviews is available on pip, but having it on MacPorts would be very nice.

Thank you!

It looks like we also need to create a port for py-param.

Unfortunately py-param and py-pyviz_comms have an issue adding the correct version name to the Framework. I get some thing like

running install_egg_info
Copying param.egg-info to /opt/local/var/macports/build/_Users_marius_Development_MacPorts_ports_python_py-param/py37-param/work/destroot/opt/local/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/param-None-py3.7.egg-info

  "details." % self.metadata.version

during destroot.

The param-None-py3.7.egg-info file should really be called param-1.8.1-py3.7.egg-info

I tried several ways of overriding the builtin mechanism from ​https://github.com/pyviz/autover - to no avail.

Can you rename it in pre-destroot? Can you post your Portfile?

py-pyviz_comms Portfile

[Schamschula (Marius Schamschula)]

The py-param has some attempts at getting the version number added commented out. The py-pyviz_comms has the exact same issue. holoviews fails to load w/o proper version numbers.

holoviews Portfile

[mf2k (Frank Schima)]

Fixed py-param Portfile. Please test if this works for you like it does for me.

[mf2k (Frank Schima)]

I'm not understanding your HoloViews Portfile. Should it simply be py-holoviews? Thus no need to python variants.

[Schamschula (Marius Schamschula)]

Frank,

I've run into this before: by convention, the final executable does not have the py prefix, i.e. certbot, not py-certbot. However, you are right, I need to move it out of the python directory.

The suggestion to rename the *--py3.7.egg-info directory worked. I also had to manually update the Version in the PKG-INFO file.
