Alexandru Croitor a0967c2a4f pro2cmake: Handle operation evaluation order when including children Instead of processing included_children operations either before or after the parent scope, collect all operations within that scope and its included children scopes, and order them based on line number information. This requires propagating line numbers for each operation as well as line numbers for each include() statement, all the way from the parser grammar to the operator evaluation routines. This should improve operation handling for included_children (via include()), but not for regular children (introduced by ifs or elses), aka this doesn't solve the whole imperative vs declarative dilemma. Sample projects where the improvement should be seen: tests/auto/gui/kernel/qguiapplication and src/plugins/sqldrivers/sqlite. This amends `f745ef0f67` Change-Id: I40b8302ba6aa09b6b9986ea60eac87de8676b469 Reviewed-by: Leander Beernaert <leander.beernaert@qt.io> Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>		2019-11-12 11:47:42 +00:00

CMake Utils

This directory holds scripts to help the porting process from qmake to cmake for Qt6.

Requirements

Python 3.7,
pipenv or pip 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

Contributing to the scripts

You can verify if the styling of a script complaint 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.
