I am asking - is this normal in any decent editor NOT to have an option to remove "white space" in between lines of code?
being answered with
Yes, the option to remove blank lines doesn't usually exist.
is a direct, clear answer to your question, and certainly doesn't justify your reaction:
Answering questions is also a skill , especially without unasked / uncalled for preaching and other innuendos and insults.
I have no idea why you show this kind of reaction to a simple (and correct) answer to exactly what your were asking for.
Then: To remove blank lines in Notepad++, I first delete all trailing spaces at end of lines (NP++ has a command for that). Then I replace two consecutive newlines with one newline. NP++ can handle both ISO standard, Mac and *nix newlines, and you have to specify the correct format for the search to match, and you have to select 'Search mode: Extended'.
I guess that any editor that can match on newlines of various kinds can be used in a similar way to remove blank lines.
My guess is that Member 14968771 does not realise that what's below the horizontal line is simply Dave's signature. He's reading it as a personalised response to his question, misconstruing it entirely and taking it as a personal dig.
I am assuming that your QP pointer is a reference to an object of QProcess Class | Qt Core 6.3.2[^]. As stated in the documentation the start method assumes the device mode as ReadWrite, which if it follows the normal rules, suggests you can write to and read from the started process. But writing will only work if the started process is waiting for input on its stdin stream. As far as I can see your started process is a simple shell pipeline to write some data to stdout and a couple of files. So it is not likely to be waiting for input from an external source.
The logical place is a tutorial on QProcess. You can only communicate with an independent process in this way, when the input and output streams are connected. The default option to the start method sets QIODeviceBase::OpenMode mode = ReadWrite. Does that mean that you can write to the process or not? Only a QT expert can advise on the answer.
#define BT_DATABASE_TEST "../../BT_DATABASE/BluetoothDatabase.txt"
constchar *command = "bluetoothctl show | tee " BT_DATABASE_TEXT " | tee /tmp/temp";
2. Maybe something like this:
std::string var = "blah_blah.txt";
std::string command = std::string("bluetoothctl show | tee ") + var + std::string("" | tee /tmp/temp");
QP->start("/bin/sh", QStringList() << "-c" << command.c_str());
Yes. If objects belong to different classes, the only way to store them in a container is to use pointers, because the container allocates the same amount of memory for each entry. If you also want the container to delete an entry when you erase it, declare it as, for example, vector<unique_ptr<T>>.
If you can handle raw pointers, then C++ smart pointers should be easy to understand. Google for C++ unique_pointer tutorial and read through a few of the returned hits. It's fairly straight forward, and in general new C++ development should use the smart pointers instead of using raw (e.g. new/delete).
Keep Calm and Carry On
