Re: [Interest] equivalent of python glob
I always use '/' for my path, I use to native path only when doing command or
when needed. I also have toWindowsPath toUnixPath functions when doing cross
platform request (non native call). The cleanPath() could be useful indeed, but
if i remeber well I had some special edge case I wanted to cover. Anyway my
unit test seem to indicate this work properly. If you come with a better
solution, I could try it, I did not spend too much time on this.

Thanks. You could do that simpler with QDir::cleanPath() and
QDir::toNativeSeparators() I think (and not have to hardcode the separator).
I got my glob working with a mix of QDir, QFileInfo and QDirIterator. I
think it's a shame there isn't something simpler built in to C++ or Qt
though.

Re: [Interest] equivalent of python glob
This is what I did for pathJoin
const QString SEPARATOR("/");
QString FileSystemUtil::pathJoin(const QStringList& paths)
{
QString rv;
for(const QString& s : paths)
{
if(!rv.isEmpty() && !rv.endsWith(SEPARATOR))
{
rv += SEPARATOR;
}
if(!rv.isEmpty() && s.startsWith(SEPARATOR))
{
rv += s.right(s.size() - SEPARATOR.size());
}
else
{
rv += s;
}
}
return rv;
}

String concatenation. You don't need a function to do it for you.

use QDir('/').entryList({ "/usr/bin/*" }), as it returns nothing.
Look at QDirIterator.
e.g., QDirIterator iter(base_folder, QStringList() << "*.*",
QDir::Files, QDirIterator::Subdirectories);
But I am looking for a method where I don't have to separate the base
folder. I want to accept user input like "/usr/bin/*" and list those
files, but I haven't found a way to provide this path directly to Qt. It
looks like I need to split off the path first.
QDirIterator behaves the same as QDir, which I tried originally as I
wrote above. Here it is tested in Python:
>>> from PyQt5 import QtCore
>>> di=QtCore.QDirIterator("/", ["/usr/bin/*"])
>>>
>>> di.next()
''
On a related note, where is the equivalent of os.path.join()?
