P3: Somewhat important Description
When doing QStandardPaths::writableLocation(...) with CacheLocation or DataLocation, Qt properly appends applicationName if we didn't pass a Generic(Cache|Data)Location argument.
However with ConfigLocation, the same path gets returned with ConfigLocation and GenericLocation. From qt5/qtbase/src/corelib/io/qstandardpaths_unix.cpp:
case DataLocation:
case GenericDataLocation:
{
QString xdgDataHome = QFile::decodeName(qgetenv("XDG_DATA_HOME"));
if (isTestModeEnabled())
xdgDataHome = QDir::homePath() + QLatin1String("/.qttest/share");
if (xdgDataHome.isEmpty())
xdgDataHome = QDir::homePath() + QLatin1String("/.local/share");
if (type == QStandardPaths::DataLocation)
appendOrganizationAndApp(xdgDataHome);
return xdgDataHome;
}
case ConfigLocation:
case GenericConfigLocation:
{
// http://standards.freedesktop.org/basedir-spec/latest/
QString xdgConfigHome = QFile::decodeName(qgetenv("XDG_CONFIG_HOME"));
if (isTestModeEnabled())
xdgConfigHome = QDir::homePath() + QLatin1String("/.qttest/config");
if (xdgConfigHome.isEmpty())
xdgConfigHome = QDir::homePath() + QLatin1String("/.config");
return xdgConfigHome;
}
As you can see, appendOrganizationAndApp(xdgConfigHome) is missing in that case.
In Windows this works correctly, so this is inconsistent with that too.
