Run scripts to generate files on server (tox/Travis)

[dpizetta]

Generate files (qss and compiled versions) on Travis, so we do not need to update every time we change .scss files and also guarantee an updated status, making PR easier.

• [ ] Check generation if not installed with editable option (-e);
• [ ] Add .gitattributes to mark auto-generated files;
  • https://thoughtbot.com/blog/github-diff-supression;
  • https://git-scm.com/docs/gitattributes;
• [ ] Prepare tox/travis-ci to execute all the process on the server-side;

Do you have the log or the errors you faced? This can help us o provide better scripts. If you have, please, comment in the #226 so I can take into account when providing the compilation on the server.

I read the CONTRIBUTING.rst file and it wasn't clear to me how to regenerate style.qss from .scss files. But I'm almost sure I'm doing it wrong as I'm not very much into Python :confused:

I tried to run scripts/process_qrc.py and got the following output:

$ ./process_qrc.py 
./process_qrc.py: line 24: Script to process QRC files (convert .qrc to _rc.py and .rcc).

The script will attempt to compile the qrc file using the following tools:

    - pyrcc4 for PyQt4 and PyQtGraph (Python)
    - pyrcc5 for PyQt5 and QtPy (Python)
    - pyside-rcc for PySide (Python)
    - pyside2-rcc for PySide2 (Python)
    - rcc for Qt4 and Qt5 (C++)

Delete the compiled files that you don't want to use manually after
running this script.

Links to understand those tools:

    - pyrcc4: http://pyqt.sourceforge.net/Docs/PyQt4/resources.html#pyrcc4
    - pyrcc5: http://pyqt.sourceforge.net/Docs/PyQt5/resources.html#pyrcc5
    - pyside-rcc: https://www.mankier.com/1/pyside-rcc
    - pyside2-rcc: https://doc.qt.io/qtforpython/overviews/resources.html (Documentation Incomplete)
    - rcc on Qt4: http://doc.qt.io/archives/qt-4.8/rcc.html
    - rcc on Qt5: http://doc.qt.io/qt-5/rcc.html

Unf! It not worked! Please, check the error(s).

I'm running Linux Mint 19.2, it uses Ubuntu 18.04's package repositories.

Well, I guess I just don't know how to run these scripts properly and set up the correct environment. Perhaps you could edit the Modifying QSS File section of CONTRIBUTING.rst and add an example command that just converts .scss files to a single .qss file.

Anyways, thank you @dpizetta and @goanpeca for your time and efforts! And this dark theme is awesome!

[dpizetta]

@tsilia thank you for the messages and comments, we will try to improve those. We appreciate your time too :)
