2011-03-26String: removing implicit numeric conversions and new approach to "if (s)".David A. Mellis
This makes explicit the String constructors that take numeric types and chars and removes the versions of concat() and operator=() and operator+() that accept numberic types. It also replaces the operator bool() with a operator that converts to a function pointer. This allows for uses like "if (s)" but not "s + 123". See: http://www.artima.com/cppsource/safebool.html. This allowed removing the disambiguating operator+() functions and relying solely on StringSumHelper and anonymous temporaries once again. Also, now treating unsigned char's like int when constructing Strings from them, i.e. String(byte(65)) is now "65" not "A". This is consistent with the new behavior of Serial.print(byte).

2011-03-13Adding additional String + operators for disambiguation.David A. Mellis
The operator bool() means that you could implicitly convert a String to a bool and then add it to it an int, for example. Which means our operator+ has to match exactly or it will be ambiguous.
2011-03-13Moving move() to __GXX_EXPERIMENTAL_CXX0X__ only, adding operator bool().David A. Mellis
2011-03-12Modifying String.concat() to return success or failure, not this.David A. Mellis
Which means you can't chain multiple concat() calls together, but you can check if they succeeded or not.
2011-03-11Don't return the string when modifying its value.David A. Mellis
Changing toLowerCase(), toUpperCase(), trim() and replace() to return void instead of a reference to the string that's just been changed. That way, it's clear that the functions modify the string they've been called on.
2011-03-11Renaming append() back to concat().David A. Mellis
2011-03-11Removing F("string") syntax for now.David A. Mellis
We should probably add something like this back in later, but I want to do one thing at a time. This removes the __FlashStringHelper class as well.

2010-11-29Redoing 448222e4b65e0cf44dfc0c494f7f76901f1fabea without all the extra files.David A. Mellis
Adds toInt() to String, WCharacter.h (from Wiring), and an SD Datalogger example.
2010-11-29Revert "added toInt() function to WString".David A. Mellis
This reverts commit 448222e4b65e0cf44dfc0c494f7f76901f1fabea.
2010-11-29added toInt() function to WStringTom Igoe
2010-08-28Changing String::toCharArray() and getBytes() to accept a buffer, rather ↵David A. Mellis
than return one. That way they don't expose the internal representation of the String class, allowing future optimization. Thanks to Paul Stoffregen.
2010-08-18Adding some basic error checking to the String class (i.e. checking for a ↵David A. Mellis
non-null buffer before modifying its contents).
2010-08-06No longer requiring WProgram.h for Print / Stream classes (replaced ↵David A. Mellis
Arduino-specific type names in String).
2010-07-27added more String examplesTom Igoe
2010-07-27Reverting changes to String class and modifying to allow + and += to work on ↵David A. Mellis
more types.

2010-07-04Adding support for printing Strings to the Print class.David A. Mellis
2010-07-04Modifying String from new/delete to malloc()/free(). Also #include'ing ↵David A. Mellis
WString.h from WProgram.h.
2010-07-04Adding WString.h and WString.cpp straight from Wiring (r. 726). Won't ↵David A. Mellis
actually work yet.
