Make Arduino IDE automatically include dependent libraries

Projects Programming
1

I have created a library that interanlly uses the Wifi library and the SPI library.

My library works perfectly, but ONLY if you also write the #include statements for both of the other libraries in the main sketch.

I notice that when using the IDE to include libraries, with some it will automatically plop in multiple #include statements when you include one library.

Is it possible to make my library do this, so that when a user selects my library from the list Arduino also includes SPI.h and WiFi.h?

I am trying to prevent the case of someone trying to use my library, not including the others, and being confused at why they are getting an error.

No it does not. The only time any #includes are added is when the .ino is converted to a .cpp

You must include all the .h's that your lib needs in your .h/.cpp files.

Perhaps I didn't word this in a way that was logical. I'll give an example.

If I select WiFi from the IDE's list of libraries, in my code I do not only get:

#include <WiFi.h>

Instead I get:

#include <WiFi.h>
#include <WiFiClient.h>
#include <WiFiServer.h>
#include <WiFiUdp.h>

When I click my own library, I do not want to only get:

#include <mylibrary.h>

I would like to get:

#include <mylibrary.h>
#include <SPI.h>
#include <WiFi.h>
