setBusesLayout while adding and removing buses simultaneously?

General JUCE discussion

Hi all,

Is there any way to setBusesLayout while simultaneously adding or removing buses as appropriate?

Currently, littered around my code are instances like the following:

    auto algLayout = algProc->getBusesLayout();
    auto sinkLayout = algLayout;
    // sync number of buses
    for (int dir = 0; dir < 2; ++dir)
    {
        const bool isInput = (dir == 0);
        int expectedNumBuses = isInput ? sinkLayout.inputBuses.size() : sinkLayout.outputBuses.size();
        int currentNumBuses = sinkProc->getBusCount(isInput);
        for (; currentNumBuses < expectedNumBuses; currentNumBuses++)
        {
            auto result = sinkProc->addBus(isInput);
            if (!result)
            {
                Logger::writeToLog("Failed to add bus to sink processor");
                return false;
            }
        }
        for (; expectedNumBuses < currentNumBuses; expectedNumBuses++)
        {
            auto result = sinkProc->removeBus(isInput);
            if (!result)
            {
                Logger::writeToLog("Failed to remove bus to sink processor");
                return false;
            }
        }
        assert(expectedNumBuses == currentNumBuses);
    }
    
    if (!sinkProc->setBusesLayout(sinkLayout))
    {
        Logger::writeToLog("Failed to set buses layout for sinkProc");
        return false;
    }

Basically:

  1. Build a layout
  2. Go through the processor and add or remove busses as necessary so bus counts match
  3. apply the bus alyout with setBusesLayout

Is there a way that 2 and 3 can be the same step? Essentially if you apply a bus layout, it adds/removes buses as necessary?

Am I over complicating things?

Thank you!
