Publish Python binding

[Fixstars-iizuka]

• Better syntax for Builder/Node/Port (Backlog)
• Design reference counting for c_ion objects (Backlog)
• Publish on PyPI
  • Package Naming
  • Versioning
  • Allows users to install by pip install <name of the module>

[xinyuli1204]

pip install <name of the module>
May I ask is it means pip install ionpy?
since pip search the package index to install. And ionpy as a package name has already been taken. Also ion-python has the exact same name with https://github.com/amazon-ion/ion-python

How about pip install ion-kit?

[xinyuli1204]

How about pip install ion-kit?

So ion-kit is the package name and ionpy as the module name?

[iitaku]

Probably we can use ion as module name and ion-kit as package name.

[iitaku]

Is it possible to include a prebuilt ion-kit binary package in the package which is installed through pip?

[xinyuli1204]

ion

you mean include libxxx.so, for example? I will check

Naming Convention

1. Package: ion-python Module: ionpy
2. Package: ion-kit Module: ion
3. Package: ion-python Module: ion

Include binary

[tool.setuptools.package-data]
ionpy = ["module/macos/*", "module/linux/*", "module/windows/*"]

[xinyuli1204]

1. reduce size
2. include ion-bb

[xinyuli1204]

2. include ion-bb

ion_bb = ctypes.cdll.LoadLibrary(ion_bb_module)

[xinyuli1204]

If Include all the prebuilt binary

@xinyuli1204 Can we create platform-specific wheels? https://packaging.python.org/en/latest/specifications/platform-compatibility-tags/

Hopefully, PyPI allows us to upload .whl packages up to 100 MB for each.

FYI, A simple line in CmakeFile seems to be fine. Tested both on linux and mac
I will push the code later and also test on TestPYPI first.

if(APPLE)
    set(CMAKE_INSTALL_RPATH "@loader_path")
elseif(UNIX)
    set(CMAKE_INSTALL_RPATH "$ORIGIN")
endif()
