Use #define from .ino in library

Hey guys,

i have a question concerning using a #define made in the sketch file in my library.
I want the user of my lib be able to set a debug #define which decides if he wants debug output or not.
(eg. #define DEBUGGING true)

To achieve this i have the following code:

.ino file:

/// PRE DEFINES
/// ============================================================================
/// 
#define INOMATION_AUTH_KEY "bWF4OjhBdHJKRk5hbXBMYzhpOEpURQ=="
#define INOMATION_DEBUGGING true

/// Webduino Settings. Decomment to activate
#define WEBDUINO_SERIAL_DEBUGGING 			2
// #define WEBDUINO_READ_TIMEOUT_IN_MS 		1000
// #define WEBDUINO_COMMANDS_COUNT 			8
// #define WEBDUINO_URL_PATH_COMMAND_LENGTH 8
// #define WEBDUINO_FAIL_MESSAGE 			"<h1>EPIC FAIL</h1>"
// #define WEBDUINO_AUTH_REALM 				"Webduino"
// #define WEBDUINO_AUTH_MESSAGE 			"<h1>401 Unauthorized</h1>"
// #define WEBDUINO_SERVER_ERROR_MESSAGE 	"<h1>500 Internal Server Error</h1>"
// #define WEBDUINO_OUTPUT_BUFFER_SIZE 		32
// #define WEBDUINO_FAVICON_DATA { 0x00, 0x00, 0x01, 0x00, 0x01, 0x00, 0x10, \

The thing is, it isnt working. The output option always is set to false… so he does not overtake the true from the ino file.

Thanks for your help.

so he does not overtake the true from the ino file.

Correct. The #define in the sketch has nothing to do with the name in the library.

There have been many attempts to do what you want to do with #defines. None of them have worked.

Ok. I already thought that there may be no solution for that. That was my last try :D

But maybe you guys have another neat solution for passing library settings to a library by the user ;)

How about adding a second constructor with an additional boolean argument. User sets it to true if they want debug on.

Or add a setDebug method to the class.

I will have a lot of settings. That would be a big and ugly constructor :D

Ah, ok, so it is not just debug on or off?

Nope. Mac-Address, IP, Debug, txPin, rxPin, etc. :D

MaxBec: Nope. Mac-Address, IP, Debug, txPin, rxPin, etc. :D

It sounds like you need a different approach. Using #defines for all that is not the correct approach.

Have methods in your class that can be called to set that stuff.
