Description
(It's not obvious where the website docs live in github, or i'd just submit a pull request)
The troubleshooter for the std::min vs arduino min macro (https://arduinojson.org/v6/troubleshooter/?utm_source=github&utm_medium=readme#compiletime/macro-min/success) says to disable std::string/std::stream support.
Just to flag there is actually a much easier fix that does not require compiler flags and should work everywhere.
Before including ArduinoJson.h, do this:
#include <Arduino.h>
#undef min
min is guaranteed to be defined in C++ so we don't have to worry that we will remove the only definition (it's also supposed to be an inline function and not a macro, which is why it conflicts in the first place)
Including the header ourselves guarantees that all the macros are defined and that the header won't be reincluded by someone else.
#undef min then removes the conflicting macro definition.
This will work:
- On all systems where someone uses ArduinoJSON
- whether the min macro exists or not.
- without removing support for std::*
Figured i would flag this.
