Add python linting

[Matthieu-LAURENT39]

This PR aims to add support for linting python files using QsciLexerPython This is still WIP as i can't get the colors to work properly, some help would be nice

[Matthieu-LAURENT39]

My issue is that i have no idea why the background color where there is no text is black

[Matthieu-LAURENT39]

ok, now it should be all good, everything seems to work fine

@gsohler i'd appreciate if you could take a quick look (not at the code, but at how it looks) so you can give some feedback

Hi Matthieu! I am absolutely excited to realize that there are more people which like to see OpenSCAD to understand Python and to integrate it very well. The Vision to have keyword highlighting and other opticial effects not only to SCAD language is fantastic. However, with better integration also the required Changes and number of changed files increase and need to get reviewed by the main OpenSCAD developer team and there are many others tasks in parallel taking their time, In the past PR related to python could merge maybe every 3 month only , so I start to consider adding yet another PR with fewer changes . Right now I thinking , whether increased demand, increased usability or rather a smaller change set will "enable" python finally in OpenSCAD :)

BTW I really like the += and -= operators now, see

matthieu i just cloned your repository now and i experienced some general cmake compilation issues. will need to look into that later ..

[Matthieu-LAURENT39]

yeah i got some cmake issues too, i could fix it by using the command cmake -DEXPERIMENTAL=1 -DENABLE_PYTHON=1 -DCRYPTOPP_INCLUDE_DIRS=/usr/include/cryptopp/ -DCRYPTOPP_LIBRARIES=/usr/lib/libcryptopp.so .. personally

However, with better integration also the required Changes and number of changed files increase and need to get reviewed

Should i change the destination branch to the python one then?

[gsohler]

yes, this cryptopp stuff is not absolutely nice yet: issue is, that the packet is called 'crypto++' on some systems and I was not able to find the "common" solution yet. Still this cryptopp is needed to "sign" code, which users trusted to. Maybe you want to send me short email to my public documented address? My cmake issues have resolved by applying the hierarchical option to git submodule. BTW I got ctest pass rate for my python branch dramatically improved, still I believe, that this would be a very quiet branch

[Matthieu-LAURENT39]

An email containing what exactly?

Nice! So i should change the PR to the python branch then?

[gsohler]

Matthieu, I looked into the colored python code and it looks great! Not sure if it makes sense to PR to my python branch, I am the only one looking into that ;) The OpenSCAD Main repository has quite some python stuff inside yet(it even has the python_active flag!) . Its just not yet visible to the user. I did enjoy very much playing the role on the "approver" side, but I feel you should PR to the main branch instead so your valuable work becomes more visible to the Developper team!

[gsohler]

In any case, thank you for your valuable contribution. I added you as a collaborator to my repo so its easier to you if you have more ideas.
