Fork of @lnjX's simple script replacing the official graphical Qt installer. It's great version pinnable alternative to the QT Online Installer which can be used in cloud CI systems for projects that can't cache large downloads.
Now both the forked project here and my aqtinstall depend on 7zip external program that prevent performance by running external processes.
Because Python 3.x supports LZMA compression algorithm(.xz), it is a good alternative to utilize it for exteract 7zip utility. Unfortunately 7zip is an archive format that is not supported by python core only.
is one which try implementing 7zip extract library.
You are welcome to attend an effort and utilize it, If you are interested in realizing thing in pure python. It is under development that can extract simple archive but fails with complex one.
