WString.h is not compatible to c++11 range-based loop

[Rotzbua]

I tried to use the new c++11 syntax with the default string class from arduino. Actually it fails because it has no begin or end.

Test-IDE: 1.6.8 (Win8.1 x64)
Board: Uno

Example code:

String temp = "abc";
for (auto tempchar : temp) {
    Serial.println(tempchar);
}

Error:

error: 'begin' was not declared in this scope
for (auto tempchar : temp) {
error: 'end' was not declared in this scope

This was already "discussed" somewhere else. No answer as I remember. I also suggest to add this feature.

I have a PR hanging around: #2179

I proposed this before C++11 was enabled (2014).
Would be nice to see this finally merged.

While we're on the subject of the String class: #3096...

Fixed with #2179
