|
|
|
> ### BREAKING CHANGES
|
|
>
|
|
> #### Support for `char` removed
|
|
>
|
|
> We cannot cast a `JsonVariant` to a `char` anymore, so the following will break:
|
|
> ```c++
|
|
> char age = doc["age"]; // error: no matching function for call to 'variantAs(VariantData*&)'
|
|
> ```
|
|
> Instead, you must use another integral type, such as `int8_t`:
|
|
> ```c++
|
|
> int8_t age = doc["age"]; // OK
|
|
> ```
|
|
>
|
|
> Similarly, we cannot assign from a `char` anymore, so the following will break:
|
|
> ```c++
|
|
> char age;
|
|
> doc["age"] = age; // error: no matching function for call to 'VariantRef::set(const char&)'
|
|
> ```
|
|
> Instead, you must use another integral type, such as `int8_t`:
|
|
> ```c++
|
|
> int8_t age;
|
|
> doc["age"] = age; // OK
|
|
> ```
|
|
> A deprecation warning with the message "Support for `char` is deprecated, use `int8_t` or `uint8_t` instead" was added to allow a smooth transition.
|
|
>
|
|
> #### `as<T>()` always returns `T`
|
|
>
|
|
> Previously, `JsonVariant::as<T>()` could return a type different from `T`.
|
|
> The most common example is `as<char*>()` that returned a `const char*`.
|
|
> While this feature simplified a few use cases, it was confusing and complicated the
|
|
> implementation of custom converters.
|
|
>
|
|
> Starting from this version, `as<T>` doesn't try to auto-correct the return type and always return `T`,
|
|
> which means that you cannot write this anymore:
|
|
>
|
|
> ```c++
|
|
> Serial.println(doc["sensor"].as<char*>()); // error: invalid conversion from 'const char*' to 'char*' [-fpermissive]
|
|
> ```
|
|
>
|
|
> Instead, you must write:
|
|
>
|
|
> ```c++
|
|
> Serial.println(doc["sensor"].as<const char*>()); // OK
|
|
> ```
|
|
>
|
|
> A deprecation warning with the message "Replace `as<char*>()` with `as<const char*>()`" was added to allow a smooth transition.
|
|
>
|
|
> #### `DeserializationError::NotSupported` removed
|
|
>
|
|
> On a different topic, `DeserializationError::NotSupported` has been removed.
|
|
> Instead of returning this error:
|
|
>
|
|
> * `deserializeJson()` leaves `\uXXXX` unchanged (only when `ARDUINOJSON_DECODE_UNICODE` is `0`)
|
|
> * `deserializeMsgPack()` replaces unsupported values with `null`s
|
|
>
|
|
> #### Const-aware `is<T>()`
|
|
>
|
|
> Lastly, a very minor change concerns `JsonVariantConst::is<T>()`.
|
|
> It used to return `true` for `JsonArray` and `JsonOject`, but now it returns `false`.
|
|
> Instead, you must use `JsonArrayConst` and `JsonObjectConst`.
|
|
|

|
|
> ### BREAKING CHANGES
|
|
>
|
|
> #### Copy-constructor of `BasicJsonDocument`
|
|
>
|
|
> In previous versions, the copy constructor of `BasicJsonDocument` looked at the source's `memoryUsage()` to choose its capacity.
|
|
> Now, the copy constructor of `BasicJsonDocument` uses the same capacity as the source.
|
|
>
|
|
> Example:
|
|
>
|
|
> ```c++
|
|
> DynamicJsonDocument doc1(64);
|
|
> doc1.set(String("example"));
|
|
>
|
|
> DynamicJsonDocument doc2 = doc1;
|
|
> Serial.print(doc2.capacity()); // 8 with ArduinoJson 6.14
|
|
> // 64 with ArduinoJson 6.15
|
|
> ```
|
|
>
|
|
> I made this change to get consistent results between copy-constructor and move-constructor, and whether RVO applies or not.
|
|
>
|
|
> If you use the copy-constructor to optimize your documents, you can use `garbageCollect()` or `shrinkToFit()` instead.
|
|
>
|
|
> #### Copy-constructor of `JsonDocument`
|
|
>
|
|
> In previous versions, it was possible to create a function that take a `JsonDocument` by value.
|
|
>
|
|
> ```c++
|
|
> void myFunction(JsonDocument doc) {}
|
|
> ```
|
|
>
|
|
> This function gives the wrong clues because it doesn't receive a copy of the `JsonDocument`, only a sliced version.
|
|
> It worked because the copy constructor copied the internal pointers, but it was an accident.
|
|
>
|
|
> From now, if you need to pass a `JsonDocument` to a function, you must use a reference:
|
|
>
|
|
> ```c++
|
|
> void myFunction(JsonDocument& doc) {}
|
|
> ```
|
|
|

|
|
> ### BREAKING CHANGES
|
|
>
|
|
> #### Comments
|
|
>
|
|
> Support for comments in input is now optional and disabled by default.
|
|
>
|
|
> If you need support for comments, you must defined `ARDUINOJSON_ENABLE_COMMENTS` to `1`; otherwise, you'll receive `InvalidInput` errors.
|
|
>
|
|
> ```c++
|
|
> #define ARDUINOJSON_ENABLE_COMMENTS 1
|
|
> #include <ArduinoJson.h>

|
> ```

|

|
|
> #### NaN and Infinity
|
|
>
|
|
> The JSON specification allows neither NaN not Infinity, but previous
|
|

v6.10.1 (2019-04-23)
|
|
-------
|
|
|
|
* Fixed error "attributes are not allowed on a function-definition"
|
|
* Fixed `deserializeJson()` not being picky enough (issue #969)

|
- `is<T>()` returns `false` if the integer `T` overflows
|
|
* Added `BasicJsonDocument` to support custom allocator (issue #876)
|
|
* Added `JsonDocument::containsKey()` (issue #938)
|
|
* Added `JsonVariant::containsKey()`
|
|

|
|
Many thanks to Daniel Schulte (aka @trilader) who implemented this feature.
|
|
* Added option ARDUINOJSON_DECODE_UNICODE to enable it
|
|
* Converted `JsonArray::copyFrom()/copyTo()` to free functions `copyArray()`
|
|
* Renamed `JsonArray::copyFrom()` and `JsonObject::copyFrom()` to `set()`
|
|
* Renamed `JsonArray::get()` to `getElement()`
|
|
* Renamed `JsonArray::add()` (without arg) to `addElement()`
|
|
* Renamed `JsonObject::get()` to `getMember()`
|
|

|
|
* Added `memoryUsage()` to `JsonArray`, `JsonObject`, and `JsonVariant`
|
|
* Added `nesting()` to `JsonArray`, `JsonDocument`, `JsonObject`, and `JsonVariant`
|
|
* Replaced `JsonDocument::nestingLimit` with an additional parameter
|
|
to `deserializeJson()` and `deserializeMsgPack()`
|
|
* Fixed uninitialized variant in `JsonDocument`
|
|
* Fixed `StaticJsonDocument` copy constructor and copy assignment
|
|
* The copy constructor of `DynamicJsonDocument` chooses the capacity according to the memory usage of the source, not from the capacity of the source.
|
|
* Added the ability to create/assign a `StaticJsonDocument`/`DynamicJsonDocument` from a `JsonArray`/`JsonObject`/`JsonVariant`
|
|

|
|
* Added `add()`, `createNestedArray()` and `createNestedObject()` to `JsonVariant`
|
|
* `JsonVariant` automatically promotes to `JsonObject` or `JsonArray` on write.
|
|
Calling `JsonVariant::to<T>()` is not required anymore.
|
|
* `JsonDocument` now support the same operations as `JsonVariant`.
|
|
Calling `JsonDocument::as<T>()` is not required anymore.
|
|
* Fixed example `JsonHttpClient.ino`
|
|
* User can now use a `JsonString` as a key or a value
