Changes since 5.11.2

  • Added JsonVariant::operator| to return a default value (see below)
  • Added a clear error message when compiled as C instead of C++ (issue #629)
  • Added detection of MPLAB XC compiler (issue #629)
  • Added detection of Keil ARM Compiler (issue #629)
  • Added an example that shows how to save and load a configuration file
  • Reworked all other examples

How to use the new feature?

If you have a block like this:

const char* ssid = root["ssid"];
if (!ssid)
  ssid = "default ssid";

You can simplify like that:

const char* ssid = root["ssid"] | "default ssid";
