Add a default constructor to the Task class

[CedricLor]

Hi,

It might be a good idea to add an explicit default constructor to the Task class.

Line 128 of TaskSchedulerDeclarations.h, add:
INLINE Task() {};

This would allow to compile libraries such as painlessMesh (which declare a bunch of Tasks without initializing them) together with option _TASK_STATUS_REQUEST.

Another question: why not use the classical header (.h) and code (.cpp) file structure instead of two .h files with different names?

It shoud already be possible to instantiate Task() without any parameters. No change is required for that.

No .CPP file is unfortunately the only way to make compilation parameters like _TASK_STATUS_REQUEST and others work with Arduino IDE.

Thanks for your answer.

It was not possible if compiled with _TASK_STATUS_REQUEST

Accordingly, I forked your lib and modified both existing constructors:

• moved the taskScheduler param first,
• undefaulted it
  and then added an explicit default constructor. Works fine this way for me anyway.

For the .CPP and conflict with Arduino IDE, I didn't know. Thanks;)

Oh, that's a bug then. Thanks for letting me know. Will fix!

Unfortunately, your solution changed the Task constructor signature and would make TS backwards-incompatible.
I was able to resolve ambiguity just by disabling default values for Status Request constructor. Seems to work.
Since Status Request enabled Tasks are a special case, it is ok for them to be explicitly constructed.
It also didn't seem to break any of my code and examples.

Will push into testing branch after a bit of testing and release together with 3.X
