Arduino JSON: change log
========================
ArduinoJson: change log
=======================
v5.0.2
------
* Fixed segmentation fault in `parseObject(String)` and `parseArray(String)`, when the
`StaticJsonBuffer` is too small to hold a copy of the string
* Fixed Clang warning "register specifier is deprecated" (issue #102)
* Fixed GCC warning "declaration shadows a member" (issue #103)
* Fixed memory alignment, which made ESP8266 crash (issue #104)
* Fixed compilation on Visual Studio 2010 and 2012 (issue #107)
v5.0.1
------
* Fixed compilation with Arduino 1.0.6 (issue #99)
v5.0.0
------
* Added support of `String` class (issues #55, #56, #70, #77)
* Added `JsonBuffer::strdup()` to make a copy of a string (issues #10, #57)
* Implicitly call `strdup()` for `String` but not for `char*` (issues #84, #87)
* Added support of non standard JSON input (issue #44)
* Added support of comments in JSON input (issue #88)
* Added implicit cast between numerical types (issues #64, #69, #93)
* Added ability to read number values as string (issue #90)
* Redesigned `JsonVariant` to leverage converting constructors instead of assignment operators (issue #66)
* 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!
v4.6
----
* Fixed segmentation fault in `DynamicJsonBuffer` when memory allocation fails (issue #92)
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, see example bellow.
* Added indented output for the JSON generator (issue #11), see example bellow.
* Added `IndentedPrint`, a decorator for `Print` to allow indented output
Example:
@ -23,7 +116,7 @@ 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:

Arduino JSON library - Generator
================================
*An elegant and efficient JSON encoder for embedded systems.*
It's design to have the most intuitive API, the smallest footprint and works without any allocation on the heap (no malloc).
It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library in any other C++ project.
Features
--------
* Elegant API, very easy to use
* Fixed memory allocation (no malloc)
* Small footprint
* Supports nested objects
* Supports indented output
* Implements Arduino's `Printable interface
* MIT License
Example
-------
JsonArray<2> array;
array.add<6>(48.756080); // <6> specifies the number of digits in the output
array.add<6>(2.302038); // (the default is 2)
JsonObject<3> root;
root["sensor"] = "gps";
root["time"] = 1351824120;
root["data"] = array;
Serial.print(root); // {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
How to use?
------------
### 1. Install the library
Download the library and extract it to:
<your Arduino Sketch folder>/libraries/ArduinoJson
### 2. Import in your sketch
Just add the following lines at the top of your `.ino` file:
#include <JsonGenerator.h>
using namespace ArduinoJson::Generator;
> ##### Having a namespace conflict?
> To be able to use both `ArduinoJson::Generator` and `ArduinoJson::Parser` in the same file, you need to do one of the followings:
>
> * Put the `using` statements into different functions
> * `using namespace ArduinoJson`, then prefix the type names by `Generator::` or `Parser::`
> * Create aliases for the namespaces or the types (C++11 only)
### 3. Create object tree
In order to generate a JSON string, you need to build the equivalent object tree. You usually start by the root which can be either a JSON Array or a JSON Object.
#### JSON Array
You create an array with the following line:
JsonArray<8> array;
See the little `<8>`? It's a template parameter that gives the capacity of the array, it's the maximum number of elements you can put in it.
> ##### About the capacity
> As stated in the feature list, this library works with a fixed memory allocation.
> This means that the size of the object must be know at the compilation time, therefore you can **not** use a variable to set the capacity of the array.
Then you can add strings, integer, booleans, etc:
array.add("bazinga!");
array.add(42);
array.add(true);
There are two syntaxes for floating point values:
array.add<4>(3.1415); // 4 digits: "3.1415"
array.add(3.14); // 2 digits: "3.14"
> ##### About floating point precision
> The overload of `add()` with 2 parameters allows you to specify the number of decimals to save in the JSON string.
> When you use the overload with one parameter, you use the default number of decimals which is two.
> Note that this behavior is the exact same as Arduino's `Print::print(double,int);` which is implemented by `Serial`.
> So you may already be familiar with it.
Finally you can add nested object to the array:
JsonArray<8> nestedArray;
array.add(nestedArray);
or
JsonObject<8> nestedObject;
array.add(nestedObject);
> ##### CAUTION! Nested objects must be in memory
> Calling `add()` makes the `JsonArray` store a pointer to the nested object.
> This is designed to avoid memory duplication.
> But it can only work if the object is in memory when `printTo()` is executed.
> For instance, don't do this:
>
> void addNestedObject()
> {
> JsonObject<2> nestedObject;
> // ...
> array.add(nestedObject); // <- DON'T !!
>
> // array now contains a pointer to a local variable that will be
> // discarded as soon as the function exits
> }
>
> For the same reason, don't do this either:
>
> for( int i=0; i<100; i++)
> {
> JsonObject<2> nestedObject;
> // ...
> array.add(nestedObject); // <- DON'T !!
> }
> // array now contains 100 pointers to the same a local variable
> // that is out of the scope anyway
#### JSON Object
You create a JSON object (ie hash-table/dictionary) with the following line:
JsonObject<8> object;
Like with the array class, there is a template parameter that gives the capacity of the object.
Then you can add strings, integer, booleans, etc:
object["key1"] = "bazinga!";
object["key2"] = 42;
object["key3"] = true;
As for the arrays, there are two syntaxes for the floating point values:
object["key4"].set<4>(3.1415); // 4 digits "3.1415"
object["key5"] = 3.1415; // default: 2 digits "3.14"
Finally you can add nested objects:
JsonArray<8> nestedArray;
object["key6"] = nestedArray;
or
JsonObject<8> nestedObject;
object["key7"] = nestedObject;
> ##### Other JsonObject functions
> * `object.add(key, value)` is a synonym for `object[key] = value`
> * `object.containsKey(key)` returns `true` is the `key` is present in `object`
> * `object.remove(key)` removes the `value` associated with `key`
### 4. Get the JSON string
There are two ways tho get the resulting JSON string.
Depending on your project, you may need to dump the string in a classic `char[]` or send it to a stream like `Serial` or `EthernetClient `.
Both ways are the easy way :-)
#### Use a classic `char[]`
Whether you have a `JsonArray` or a `JsonObject`, simply call `printTo()` with the destination buffer, like so:
char buffer[256];
array.printTo(buffer, sizeof(buffer));
> ##### Want an indented output?
> By default the generated JSON is as small as possible. It contains no extra space, nor line break.
> But if you want an indented, more readable output, you can.
> Simply call `prettyPrintTo` instead of `printTo()`:
>
> array.prettyPrintTo(buffer, sizeof(buffer));
#### Send to a stream
It's very likely that the generated JSON will end up in a stream like `Serial` or `EthernetClient `, so you can save some time and memory by doing this:
Serial.print(array);
or
array.printTo(Serial);
> ##### About the Printable interface
> `JsonArray` and `JsonObject` implement Arduino's `Printable` interface.
> This is why you can call `Serial.print()` like in the example above.
> You can do the same with any other implementation of `Print`: `HardwareSerial`, `SoftwareSerial`, `LiquidCrystal`, `EthernetClient`, `WiFiClient`, `Wire`...
Memory usage
------------
Here are the size of the main classes of the library.
This table is for an 8-bit Arduino, types would be bigger on a 32-bit processor.
| Type | Size in bytes |
| --------------------| ------------- |
| JsonArray&lt;N&gt; | 8 + 6 x N |
| JsonObject&lt;N&gt; | 8 + 8 x N |
Code size
---------
The following values has been obtained with Arduino IDE 1.0.5, targeting an Arduino Duelmilanove with an ATmega 328.
### Minimum setup
| Function | Size |
| ----------------------------------- | ---- |
| `JsonObjectBase::printTo()` | 234 |
| `EscapedString::printTo()` | 196 |
| `JsonArrayBase::printTo()` | 164 |
| `Print::print(char const*)` | 146 |
| `JsonObjectBase::operator[]` | 114 |
| `JsonObjectBase::getMatchingPair()` | 72 |
| `JsonValue::printPrintableTo()` | 40 |
| `JsonValue::printStringTo()` | 12 |
### Additional space for integers
| Function | Size |
| ---------------------------- | ---- |
| `Print::print(long, int)` | 328 |
| `JsonValue::printLongTo()` | 22 |
### Additional space for floating point
| Function | Size |
| ------------------------------ | ---- |
| `Print::print(double, int)` | 1548 |
| `JsonValue::printDouleTo<2>()` | 22 |

Arduino JSON library - Parser
=============================
This library is an thin C++ wrapper around the *jsmn* tokenizer: http://zserge.com/jsmn.html
It's design to be very lightweight, works without any allocation on the heap (no malloc) and supports nested objects.
It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library in any other C++ project.
Features
--------
* Based on the well-proven [jsmn](http://zserge.com/jsmn.html) tokenizer
* Supports nested objects
* Elegant API, very easy to use
* Fixed memory allocation (no malloc)
* Small footprint
* MIT License
Example
-------
JsonParser<32> parser;
char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
JsonObject root = parser.parse(json);
char* sensor = root["sensor"];
long time = root["time"];
double latitude = root["data"][0];
double longitude = root["data"][1];
How to use ?
-------------
### 1. Install the library
Download the library and extract it to:
<your Arduino Sketch folder>/libraries/ArduinoJson
### 2. Import in your sketch
Just add the following lines at the top of your `.ino` file:
#include <JsonParser.h>
using namespace ArduinoJson::Parser;
> ##### Having a namespace conflict?
> To be able to use both `ArduinoJson::Generator` and `ArduinoJson::Parser` in the same file, you need to do one of the followings:
>
> * Put the `using` statements into different functions
> * `using namespace ArduinoJson`, then prefix the type names by `Generator::` or `Parser::`
> * Create aliases for the namespaces or the types (C++11 only)
### 3. Create a parser
To extract data from the JSON string, you need to create a `JsonParser`, and specify the number of token you allocate for the parser itself:
JsonParser<32> parser;
> #### How to choose the number of tokens ?
> A token is an element of the JSON object: either a key, a value, an object or an array.
> As an example the `char json[]` on the top of this page contains 12 tokens (don't forget to count 1 for the whole object and 1 more for the array itself).
> The more tokens you allocate, the more complex the JSON can be, but also the more memory is occupied.
> Each token takes 8 bytes, so `sizeof(JsonParser<32>)` is 256 bytes which is quite big in an Arduino with only 2KB of RAM.
> Don't forget that you also have to store the JSON string in RAM and it's probably big.
> 32 tokens may seem small, but it's very decent for an 8-bit processor, you wouldn't get better results with other JSON libraries.
### 4. Extract data
To use this library, you need to know beforehand what is the type of data contained in the JSON string, which is very likely.
The root object has to be either an object (like `{"key":"value"}`) or an array (like `[1,2]`).
The nested objects can be either arrays, booleans, objects, numbers or strings.
If you need other type, you can get the string value and parse it yourself.
#### Object
Consider we have a `char json[]` containing to the following JSON string:
{
"sensor":"gps",
"time":1351824120,
"data":[48.756080,2.302038]
}
In this case the string contains a JSON object, so you need to extract a `JsonObject`:
JsonObject root = parser.parse(json);
To check if the parsing was successful, you must check:
if (!root.success())
{
// Parsing fail: could be an invalid JSON, or too many tokens
}
And then extract the member you need:
char* sensor = root["sensor"];
long time = root["time"];
double latitude = root["data"][0];
double longitude = root["data"][1];
You can also iterate through the key-value pairs of the object:
for (JsonObjectIterator i=root.begin(); i!=root.end(); ++i)
{
Serial.println(i.key());
Serial.println((char*)i.value());
}
#### Array
Consider we have a `char json[]` containing to the following JSON string:
[
[ 1.2, 3.4 ],
[ 5.6, 7.8 ]
]
In this case the root object of the JSON string is an array, so you need to extract a `JsonArray`:
JsonArray root = parser.parse(json);
To check if the parsing was successful, you must check:
if (!root.success())
{
// Parsing fail: could be an invalid JSON, or too many tokens
}
And then extract the content by its index in the array:
double a = root[0][0];
double b = root[0][1];
double c = root[1][0];
double d = root[1][1];
You can also iterate through the key-value pairs of the object:
for (JsonArrayIterator i=array.begin(); i!=array.end(); ++i)
{
Serial.println((char*)*i);
}
Common pitfalls
---------------
### 1. Not enough tokens
By design, the library has no way to tell you why `JsonParser::parse()` failed.
There are basically two reasons why they may fail:
1. the JSON string is invalid
2. the JSON string contains more tokens that the parser can store
So, if you are sure the JSON string is correct and you still can't parse it, you should slightly increase the number of token of the parser.
### 2. Not enough memory
You may go into unpredictable trouble if you allocate more memory than your processor really has.
It's a very common issue in embedded development.
To diagnose this, look at every big objects in you code and sum their size to check that they fit in RAM.
For example, don't do this:
char json[1024]; // 1 KB
JsonParser<64> parser; // 512 B
because it may be too big for a processor with only 2 KB: you need free memory to store other variables and the call stack.
That is why an 8-bit processor is not able to parse long and complex JSON strings.
### 3. JsonParser not in memory
To reduce the memory consumption, `JsonValue`, `JsonArray` and `JsonObject` contains pointer to the token that are inside the `JsonParser`. This can only work if the `JsonParser` is still in memory.
For example, don't do this:
JsonArray getArray(char* json)
{
JsonParser<16> parser;
return parser.parseArray(parser);
}
because the local variable `parser` will be *removed* from memory when the function `getArray()` returns, and the pointer inside `JsonArray` will point to an invalid location.
### 4. JSON string is altered
This will probably never be an issue, but you need to be aware of this feature.
When you pass a `char[]` to `JsonParser::parse()`, the content of the string will be altered to add `\0` at the end of the tokens.
This is because we want functions like `JsonArray::getString()` to return a null-terminating string without any memory allocation.
Memory usage
------------
Here are the size of the main classes of the library.
This table is for an 8-bit Arduino, types would be bigger on a 32-bit processor.
| Type | Size in bytes |
| ------------ | ------------- |
| `Parser<N>` | 4 + 8 x N |
| `JsonArray` | 4 |
| `JsonObject` | 4 |
| `JsonValue` | 4 |
Code size
---------
The sizes have been obtained with Arduino IDE 1.0.5 for a Duemilanove.
### Minimum setup
| Function | Size |
| ------------------------------------ | ---- |
| `jsmn_parse()` | 962 |
| `JsonValue::operator[](char const*)` | 218 |
| `JsonParserBase::parse()` | 116 |
| `JsonValue::operator[](int)` | 108 |
| `strcmp()` | 18 |
### Additional space for integers
| Function | Size |
| ---------------------------- | ---- |
| `strtol()` | 606 |
| `JsonValue::operator long()` | 94 |
### Additional space for floating points
| Function | Size |
| -------------------------------- | ----- |
| `strtod()` | 1369 |
| `JsonValue::operator double()` | 82 |

Arduino JSON library
====================
[![Build status](https://ci.appveyor.com/api/projects/status/m7s53wav1l0abssg/branch/master?svg=true)](https://ci.appveyor.com/project/bblanchon/arduinojson/branch/master) [![Build Status](https://travis-ci.org/bblanchon/ArduinoJson.svg?branch=master)](https://travis-ci.org/bblanchon/ArduinoJson) [![Coverage Status](https://img.shields.io/coveralls/bblanchon/ArduinoJson.svg)](https://coveralls.io/r/bblanchon/ArduinoJson?branch=master)
*An elegant and efficient JSON library for embedded systems.*
It's design to have the most intuitive API, the smallest footprint and works without any allocation on the heap (no malloc).
It's designed to have the most intuitive API, the smallest footprint and works without any allocation on the heap (no malloc).
It has been written with Arduino in mind, but it isn't linked to Arduino libraries so you can use this library in any other C++ project.
Features
--------
* JSON decoding: [more details here](/JsonParser/)
* JSON encoding: [more details here](/JsonGenerator/)
* Elegant API, very easy to use
* Fixed memory allocation (no malloc)
* JSON decoding (comments are supported)
* JSON encoding (with optional indentation)
* Elegant API, very easy to use
* Efficient (no malloc, nor copy)
* Portable (written in C++98)
* Self-contained (no external dependency)
* Small footprint
* MIT License
Feature comparison
------------------
Quick start
-----------
| Library | Memory allocation | Nested objects | Parser size | Encoder size |
| ------------ | ----------------- | -------------- | ----------- | ------------- |
| Arduino JSON | static | yes | 2642 Bytes | 862 bytes |
| json-arduino | dynamic | no | 3348 (+27%) | not supported |
| aJson | dynamic | yes | 5088 (+93%) | 4678 (+540%) |
#### Decoding / Parsing
"Parser size" was measured with a program parsing `{"sensor":"outdoor","value":25.6}`.
For each library, I wrote a program that extracts a string and a float. I subtracted the size of a program doing the same without any JSON parsing involved. [Source files are here](https://gist.github.com/bblanchon/e8ba914a7109f3642c0f).
char json[] = "{\"sensor\":\"gps\",\"time\":1351824120,\"data\":[48.756080,2.302038]}";
"Encoder size" was measured with a program generating `{"sensor":"outdoor","value":25.6}`.
[Source files are here](https://gist.github.com/bblanchon/60224e9dcfeab4ddc7e9).
StaticJsonBuffer<200> jsonBuffer;
In each case the target platform was an Arduino Duemilanove and Arduino IDE 1.0.5 was used.
JsonObject& root = jsonBuffer.parseObject(json);
Links: [json-arduino](https://github.com/not404/json-arduino), [aJson](https://github.com/interactive-matter/aJson)
const char* sensor = root["sensor"];
long time = root["time"];
double latitude = root["data"][0];
double longitude = root["data"][1];
#### Encoding / Generating
StaticJsonBuffer<200> jsonBuffer;
JsonObject& root = jsonBuffer.createObject();
root["sensor"] = "gps";
root["time"] = 1351824120;
JsonArray& data = root.createNestedArray("data");
data.add(48.756080, 6); // 6 is the number of decimals to print
data.add(2.302038, 6); // if not specified, 2 digits are printed
root.printTo(Serial);
// This prints:
// {"sensor":"gps","time":1351824120,"data":[48.756080,2.302038]}
