Portfile for py-libnacl

[cro (C. R. Oldham)]

I respectfully submit the attached Portfile for libnacl, a Python binding for the libsodium crypto library, which is already part of MacPorts. libnacl is a dependency for Salt when RAET is the transport.

Thanks. Some issues:

• distname and homepage should not be set; the defaults from the github portgroup should be fine
• The dependency on port:py-six should be changed to a dependency on port:py${python.version}-six
• Is it your intention to submit a port "libnacl" (per the Port field and description of this ticket) — an application that happens to use python? If so:
  • the name py-libnacl line should be removed, allowing the default name libnacl set by the github portgroup to be used
• Otherwise, if it is your intention to submit a port "py-libnacl" (per the title of this ticket and the name line in the portfile) — a python module for use by other ports? If so:
  • The dependencies on port:py${python.version}-setuptools and port:py${python.version}-six and should be inside an if {${name} ne ${subport}} block
  • python.default_version 27 should be changed to python.versions 27

Hi Ryan,

Some questions:

The dependency on port:py-six should be changed to a dependency on port:py${python.version}-six

I'm confused--six is a compatibility library and I see there is a 'py-six' port as well as a one for py26, py27, py34, etc. Why does the py-six port exist?

libnacl is a python binding to libsodium. It's compatible with Python 2.6 through 3.4. Is there a way to create a Portfile that will result in ports for all those Python versions or do I need to create a separate Portfile for each?

Replying to cr@…:

All python module ports are made this way. There is a py-whatever portfile, which creates "subports" for each version of python, e.g. py27-whatever, py34-whatever, etc. based on the python.versions option. The main py-whatever port is not meant to be installed; installing it serves no purpose; the only thing it installs is a readme saying it is a stub port.

Then what you want is to make a py-libnacl port and set python.versions 27 34. (We're in the process of excising python 2 < 2.7 and python 3 < 3.4 from MacPorts so there's no need to create those versions.)

OK, updated Portfile for py-libnacl is attached.
