I do not understand why I am getting the error.

/mnt/A_BT_DEC10/A_MAY_9/A_APR9_MAR7_MAR19_CLEAN/A_BT_LIBRARY/A_DEC17_Bluetoothctl_Dialog_V1/mainwindow_bluewtoothctl_dialog.cpp:55: error: expected expression

all I want is to assign plain text to Qt version of string.

C++

QString Commands = 
        "
        list		List available controllers
        show		Controller information
        select		Select default controller
        devices		List available devices
        paired-devices	List paired devices
        system-alias	Set controller alias
        reset-alias	Reset controller alias
        power		Set controller power
        pairable	Set controller pairable mode
        discoverable	Set controller discoverable mode
        discoverable-timeout	Set discoverable timeout
        agent		Enable/disable agent with given capability
        default-agent	Set agent as the default one
        advertise	Enable/disable advertising with given type
        set-alias	Set device alias
        scan		Scan for devices
        info		Device information
        pair		Pair with device
        cancel-pairing	Cancel pairing with device
        trust		Trust device
        untrust		Untrust device
        block		Block device
        unblock		Unblock device
        remove		Remove device
        connect		Connect device
        disconnect	Disconnect device
        ";

What I have tried:

No problem with comma separated items

C++

QString Command_Test = " list	,	List available controllers";

My objective is to assign plain text, as stated.
AFTER I get the assignment I like to analyze the text and extract specific.
I am trying to avoid massaging the text BEFORE, as you did.
It is impractical to do so in the long run.
Thanks for your suggestion...

1: I think maybe you replied at the wrong place, and this should be a reply to one of the solutions, below
2: If this is a static string, why go through the work of extracting things later? Why not just create your extracted objects at the get go? Seems like unnecessary work to me, with the added possibility of having to debug later. Creating the aggregate string from those objects shouldn't pose too much difficulty.

Solution 3

C++ provides raw string literals: String literal - cppreference.com[^].

My 5.
I always forget about raw string literals. :(
