Unfortunately qmake does not have operator precedence in conditions, and each sub-expression is simply evaluated left to right. So c1|c2:c3 is evaluated as (c1|c2):c3 and not c1|(c2:c3). To handle that in pro2cmake, wrap each condition sub-expression in parentheses. It's ugly, but there doesn't seem to be another way of handling it, because SymPy uses Python operator precedence for condition operators, and it's not possible to change the precendece.

CMake Utils
This directory holds scripts to help the porting process from qmake
to cmake
for Qt6.
Requirements
- Python 3.7,
pipenv
orpip
to manage the modules.
Python modules
Since Python has many ways of handling projects, you have a couple of options to install the dependencies of the scripts:
Using pipenv
The dependencies are specified on the Pipfile
, so you just need to run
pipenv install
and that will automatically create a virtual environment
that you can activate with a pipenv shell
.
Using pip
It's highly recommended to use a virtualenvironment
to avoid conflict with other packages that are already installed: pip install virtualenv
.
- Create an environment:
virtualenv env
, - Activate the environment:
source env/bin/activate
(on Windows:source env\Scripts\activate.bat
) - Install the requirements:
pip install -r requirements.txt
If the pip install
command above doesn't work, try:
python3.7 -m pip install -r requirements.txt
Contributing to the scripts
You can verify if the styling of a script is compliant with PEP8, with a couple of exceptions:
Install flake8 (pip install flake8
) and run it
on the script you want to test:
flake8 <file>.py --ignore=E501,E266,W503
E501
: Line too long (82>79 characters),E266
: Too many leading '#' for block comment,W503
: Line break occurred before a binary operator)
You can also modify the file with an automatic formatter,
like black (pip install black
),
and execute it:
black -l 100 <file>.py
Using Qt's maximum line length, 100.
