As system() called PDF controllers are removed, test_pdfcontroller can be
simplified because PyMuPDF will use the mocked screen.
Get rid of the platform-dependent screen size obtaining which gets rid of
the Xlib dependency.
- Optional argument to check Linux distro
- Add a test for the new argument
- Add some other tests to expand test coverage
- Remove Windows from testing
- If "distro" module is missing, create a replacement that returns False
Use QCollator as new collator to get rid of the PyICU dependency.
Simplify the natural sorting with its numeric mode.
Simplify one test that is heavily dependent on implementation.
Run one sorting test on macOS which was disabled.
Move the startup script so that its name does not
conflict with the openlp namespace.
Codify scripts/check_dependencies.py in setup.py.
The name on PyPI is used to declare the dependencies.
This is a first step to enable OpenLP distribution via
PyPI.
The differences are:
* pyenchant and pyodbc are declared optional because
they are optional in the code and pyenchant is not
maintained anymore.
* pyenchant's required version is set to 1.6 not only
for windows. This version is quite old.
* The 5.0 version checks for PyQt5 are left out because
this is the first version anyway.
* LibreOffice's uno does not exist on PyPI
* sqlite3, asyncio and mock are available in Python
>= 3.4 anyway and not noted as dependencies.
* six is not defined as dependency because the code
should be py3 only.
The situation with regards to platform wheels being
published looks quite promising.
As Linux users typically install via their package
manager wheel availability is not as import for them
as for Win or Mac users.
Both of them are available for most dependencies with
native extensions.
The few exceptions:
* PyICU does not publish any platform wheels.
More info: https://github.com/ovalhub/pyicu/issues/79
* mysql-connector-python does not publish win32 wheels.
* pyenchant does not publish win64 wheels.
The wheels are typically available for Py=2.7 and Py>=3.4,
although some (mysql-connector-python, PyQt5, pywin32)
need Py>=3.5
