the _version.py file is autogenerated at build time from git tag using setuptools_scm; the pyclipper.__version__ variable exports that, as it's common in python packaging. This allows clients to import pyclipper and check its __version__ without needing to query the package metadata (which may be missing when pyclipper is embedded in native applications).

Note on using the setup.py:
|
|
setup.py operates in 2 modes that are based on the presence of the 'dev' file in the root of the project.
|
|
- When 'dev' is present, Cython will be used to compile the .pyx sources. This is the development mode
|
|
(as you get it in the git repository).
|
|
- When 'dev' is absent, C/C++ compiler will be used to compile the .cpp sources (that were prepared in
|
|
in the development mode). This is the distribution mode (as you get it on PyPI).
|
|
|
|
This way the package can be used without or with an incompatible version of Cython.
|
|
|
|
The idea comes from: https://github.com/MattShannon/bandmat
