ArduinoJson: change log
|
|
=======================
|
|
|
|
v5.0 (currently in beta)
|
|
----
|
|
|
|
* Added support of `String` class (issue #55, #56, #70, #77)
|
|
* Added support of non standard JSON input (issue #44)
|
|
* Redesigned `JsonVariant` to leverage converting constructors instead of assignment operators
|
|
* Switched to new the library layout (requires Arduino 1.0.6 or above)
|
|
|
|
**BREAKING CHANGES**:
|
|
- `JsonObject::add()` was renamed to `set()`
|
|
- `JsonArray::at()` and `JsonObject::at()` were renamed to `get()`
|
|
- Number of digits of floating point value are now set with `double_with_n_digits()`
|
|
|
|
**Personal note about the `String` class**:
|
|
Support of the `String` class has been added to the library because many people use it in their programs.
|
|
However, you should not see this as an invitation to use the `String` class.
|
|
The `String` class is **bad** because it uses dynamic memory allocation.
|
|
Compared to static allocation, it compiles to a bigger, slower program, and is less predictable.
|
|
You certainly don't want that in an embedded environment!
|
|
|
|
v4.5
|
|
----
|
|
|
|
* Fixed buffer overflow when input contains a backslash followed by a terminator (issue #81)
|
|
|
|
**Upgrading is recommended** since previous versions contain a potential security risk.
|
|
|
|
Special thanks to [Giancarlo Canales Barreto](https://github.com/gcanalesb) for finding this nasty bug.
|
|
|
|
v4.4
|
|
----
|
|
|
|
* Added `JsonArray::measureLength()` and `JsonObject::measureLength()` (issue #75)
|
|
|
|
v4.3
|
|
----
|
|
|
|
* Added `JsonArray::removeAt()` to remove an element of an array (issue #58)
|
|
* Fixed stack-overflow in `DynamicJsonBuffer` when parsing huge JSON files (issue #65)
|
|
* Fixed wrong return value of `parseArray()` and `parseObject()` when allocation fails (issue #68)
|
|
|
|
v4.2
|
|
----
|
|
|
|
* Switched back to old library layout (issues #39, #43 and #45)
|
|
* Removed global new operator overload (issue #40, #45 and #46)
|
|
* Added an example with EthernetServer
|
|
|
|
v4.1
|
|
----
|
|
|
|
* Added DynamicJsonBuffer (issue #19)
|
|
|
|
v4.0
|
|
----
|
|
|
|
* Unified parser and generator API (issue #23)
|
|
* Updated library layout, now requires Arduino 1.0.6 or newer
|
|
|
|
**BREAKING CHANGE**: API changed significantly, see [Migrating code to the new API](https://github.com/bblanchon/ArduinoJson/wiki/Migrating-code-to-the-new-API).
|
|
|
|
|
|
v3.4
|
|
----
|
|
|
|
* Fixed escaped char parsing (issue #16)
|
|
|
|
|
|
v3.3
|
|
----
|
|
|
|
* Added indented output for the JSON generator (issue #11), see example bellow.
|
|
* Added `IndentedPrint`, a decorator for `Print` to allow indented output
|
|
|
|
Example:
|
|
|
|
JsonOject<2> json;
|
|
json["key"] = "value";
|
|
json.prettyPrintTo(Serial);
|
|
|
|
v3.2
|
|
----
|
|
|
|
* Fixed a bug when adding nested object in `JsonArray` (bug introduced in v3.1).
|
|
|
|
v3.1
|
|
----
|
|
|
|
* Calling `Generator::JsonObject::add()` twice with the same `key` now replaces the `value`
|
|
* Added `Generator::JsonObject::operator[]`, see bellow the new API
|
|
* Added `Generator::JsonObject::remove()` (issue #9)
|
|
|
|
Old generator API:
|
|
|
|
JsonObject<3> root;
|
|
root.add("sensor", "gps");
|
|
root.add("time", 1351824120);
|
|
root.add("data", array);
|
|
|
|
New generator API:
|
|
|
|
JsonObject<3> root;
|
|
root["sensor"] = "gps";
|
|
root["time"] = 1351824120;
|
|
root["data"] = array;
|
|
|
|
v3.0
|
|
----
|
|
|
|
* New parser API, see bellow
|
|
* Renamed `JsonHashTable` into `JsonObject`
|
|
* Added iterators for `JsonArray` and `JsonObject` (issue #4)
|
|
|
|
Old parser API:
|
|
|
|
JsonHashTable root = parser.parseHashTable(json);
|
|
|
|
char* sensor = root.getString("sensor");
|
|
long time = root.getLong("time");
|
|
double latitude = root.getArray("data").getDouble(0);
|
|
double longitude = root.getArray("data").getDouble(1);
|
|
|
|
New parser API:
|
|
|
|
JsonObject root = parser.parse(json);
|
|
|
|
char* sensor = root["sensor"];
|
|
long time = root["time"];
|
|
double latitude = root["data"][0];
|
|
double longitude = root["data"][1];
|
|
|
|
v2.1
|
|
----
|
|
|
|
* Fixed case `#include "jsmn.cpp"` which caused an error in Linux (issue #6)
|
|
* Fixed a buffer overrun in JSON Parser (issue #5)
|
|
|
|
v2.0
|
|
----
|
|
|
|
* Added JSON encoding (issue #2)
|
|
* Renamed the library `ArduinoJsonParser` becomes `ArduinoJson`
|
|
|
|
**Breaking change**: you need to add the following line at the top of your program.
|
|
|
|
using namespace ArduinoJson::Parser;
|
|
|
|
v1.2
|
|
----
|
|
|
|

|
|
|
|
v1.1
|
|
----
|
|
|

|
|
* Fixed parsing bug when the JSON contains multi-dimensional arrays
|
