What Hacker News says

https://github.com/qt/qtbase/blob/5.11/src/widgets/kernel/qw... is the largest no-nonsense C++ file I've ever seen https://github.com/borgbackup/borg/blob/master/src/borg/arch... ditto for Python Personally files this large become just very annoying overall. Code review tools tend to become slow on them (e.g. Gerrit is super-slow with files that are quite a bit smaller than qwidget.cpp), navigation is only possible via symbols, the import / include area becomes a huge mess (which also tends to generate constant merge conflicts, because imports are a common hot area for writes) etc.
In µUBSan: clean-room reimplementation of the Undefined Behavior Sanitizer runtime
Part of this is that UI toolkits do more and more disgusting things in order to preserve this behavior. Windows allows the foreground window to activate other windows "owned by the same app" so that existing applications don't break. The implementation, for this, of course, is a pile of heuristics [0]. Qt, steadfast in its duty to be as annoying as possible, pretends it is part of the foreground app when you call activate() by calling AttachThreadInput [1]. [0] Documented heuristics, even. https://msdn.microsoft.com/en-us/library/windows/desktop/ms6... [1] https://github.com/qt/qtbase/blob/5.11/src/plugins/platforms...
In Ask HN: What's wrong about Windows/macOS/GNU-Linux as of now?
> Is that because your code must be precompiled with moc before it's legal C++? That's... not how moc works at all. Moc parse your header files and generates additional cpp files from it which contain boilerplate for reflection and signals. So no static analyzer has any problem parsing Qt code... (I use cppcheck, coverity, clang-analyzer, clang-tidy) The "special" Qt keywords like signal, slot, etc... are just trivial macros: https://github.com/qt/qtbase/blob/5.10/src/corelib/kernel/qo... "signals" is just defined as "public", "slots" and "emit" as nothing. Your compiler compiles your source as-is. If you really don't like moc, there's a way to get its features natively with C++14 compilers (and uglier macros) : https://github.com/woboq/verdigris
