-# JSON for Modern C++
-
-*What if JSON was part of modern C++?*
-
-[](https://travis-ci.org/nlohmann/json)
-[](https://coveralls.io/r/nlohmann/json)
-[](http://github.com/nlohmann/json/issues)
-
-## Design goals
-
-There are myriads of [JSON](http://json.org) libraries out there, and each may even have its reason to exist. Our class had these design goals:
-
-- **Intuitive syntax**. In languages such as Python, JSON feels like a first class data type. We used all the operator magic of modern C++ to achieve the same feeling in your code. Check out the [examples below](#examples) and the [reference](https://github.com/nlohmann/json/blob/master/doc/Reference.md), and you know, what I mean.
-
-- **Trivial integration**. Our whole code consists of a class in just two files: A header file `json.h` and a source file `json.cc`. That's it. No library, no subproject, no dependencies. The class is written in vanilla C++11. All in all, everything should require no adjustment of your compiler flags or project settings.
-
-- **Serious testing**. Our class is heavily [unit-tested](https://github.com/nlohmann/json/blob/master/test/json_unit.cc) and covers [100%](https://coveralls.io/r/nlohmann/json) of the code, including all exceptional behavior. Furthermore, we checked with [Valgrind](http://valgrind.org) that there are no memory leaks.
-
-Other aspects were not so important to us:
-
-- **Memory efficiency**. Each JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). We use the following C++ data types: `std::string` for strings, `int64_t` or `double` for numbers, `std::map` for objects, `std::vector` for arrays, and `bool` for Booleans. We know that there are more efficient ways to store the values, but we are happy enough right now.
-
-- **Speed**. We currently implement the parser as naive [recursive descent parser](http://en.wikipedia.org/wiki/Recursive_descent_parser) with hand coded string handling. It is fast enough, but a [LALR-parser](http://en.wikipedia.org/wiki/LALR_parser) with a decent regular expression processor should be even faster (but would consist of more files which makes the integration harder).
-
-- **Rigorous standard compliance**. Any [compliant](http://json.org) JSON file can be read by our class, and any output of the class is standard-compliant. However, we do not check for some details in the format of numbers and strings. For instance, `-0` will be treated as `0` whereas the standard forbids this. Furthermore, we allow for more escape symbols in strings as the JSON specification. While this may not be a problem in reality, we are aware of it, but as long as we have a hand-written parser, we won't invest too much to be fully compliant.
-
-## Integration
-
-The two required source files are in the `src` directory. All you need to do is add
-
-```cpp
-#include "json.h"
-
-// for convenience
-using json = nlohmann::json;
-```
-
-to the files you want to use JSON objects. Furthermore, you need to compile the file `json.cc` and link it to your binaries. Do not forget to set the necessary switches to enable C++11 (e.g., `-std=c++11` for GCC and Clang).
-
-If you want a single header file, use the `json.h` file from the `header_only` directory.
-
-## Examples
-
-Here are some examples to give you an idea how to use the class.
-
-Assume you want to create the JSON object
-
-```json
-{
- "pi": 3.141,
- "happy": true,
- "name": "Niels",
- "nothing": null,
- "answer": {
- "everything": 42
- },
- "list": [1, 0, 2],
- "object": {
- "currency": "USD",
- "value": 42.99
- }
-}
-```
-
-With the JSON class, you could write:
-
-```cpp
-// create an empty structure (null)
-json j;
-
-// add a number that is stored as double (note the implicit conversion of j to an object)
-j["pi"] = 3.141;
-
-// add a Boolean that is stored as bool
-j["happy"] = true;
-
-// add a string that is stored as std::string
-j["name"] = "Niels";
-
-// add another null object by passing nullptr
-j["nothing"] = nullptr;
-
-// add an object inside the object
-j["answer"]["everything"] = 42;
-
-// add an array that is stored as std::vector (using an initializer list)
-j["list"] = { 1, 0, 2 };
-
-// add another object (using an initializer list of pairs)
-j["object"] = { {"currency", "USD"}, {"value", 42.99} };
-
-// instead, you could also write (which looks very similar to the JSON above)
-json j2 = {
- {"pi", 3.141},
- {"happy", true},
- {"name", "Niels"},
- {"nothing", nullptr},
- {"answer", {
- {"everything", 42}
- }},
- {"list", {1, 0, 2}},
- {"object", {
- {"currency", "USD"},
- {"value", 42.99}
- }}
-};
-```
-
-Note that in all theses cases, you never need to "tell" the compiler which JSON value you want to use. If you want to be explicit or express some edge cases, the functions `json::array` and `json::object` will help:
-
-```cpp
-// ways to express the empty array []
-json empty_array_implicit = {{}};
-json empty_array_explicit = json::array();
-
-// a way to express the empty object {}
-json empty_object_explicit = json::object();
-
-// a way to express an _array_ of key/value pairs [["currency", "USD"], ["value", 42.99]]
-json array_not_object = { json::array({"currency", "USD"}), json::array({"value", 42.99}) };
-```
-
-### Serialization / Deserialization
-
-You can create an object (deserialization) by appending `_json` to a string literal:
-
-```cpp
-// create object from string literal
-json j = "{ \"happy\": true, \"pi\": 3.141 }"_json;
-
-// or even nicer (thanks http://isocpp.org/blog/2015/01/json-for-modern-cpp)
-auto j2 = R"(
- {
- "happy": true,
- "pi": 3.141
- }
-)"_json;
-
-// or explicitly
-auto j3 = json::parse("{ \"happy\": true, \"pi\": 3.141 }");
-```
-
-You can also get a string representation (serialize):
-
-```cpp
-// explicit conversion to string
-std::string s = j.dump(); // {\"happy\":true,\"pi\":3.141}
-
-// serialization with pretty printing
-std::cout << j.dump(4) << std::endl;
-// {
-// "happy": true,
-// "pi": 3.141
-// }
-```
-
-You can also use streams to serialize and deserialize:
-
-```cpp
-// deserialize from standard input
-json j;
-j << std::cin;
-
-// serialize to standard output
-std::cout << j;
-```
-
-These operators work for any subclasses of `std::istream` or `std::ostream`.
-
-### STL-like access
-
-We designed the JSON class to behave just like an STL container:
-
-```cpp
-// create an array using push_back
-json j;
-j.push_back("foo");
-j.push_back(1);
-j.push_back(true);
-
-// iterate the array
-for (json::iterator it = j.begin(); it != j.end(); ++it) {
- std::cout << *it << '\n';
-}
-
-// range-based for
-for (auto element : j) {
- std::cout << element << '\n';
-}
-
-// getter/setter
-const std::string tmp = j[0];
-j[1] = 42;
-bool foo = j.at(2);
-
-// other stuff
-j.size(); // 3 entries
-j.empty(); // false
-j.type(); // json::value_t::array
-j.clear(); // the array is empty again
-
-// comparison
-j == "[\"foo\", 1, true]"_json; // true
-
-// create an object
-json o;
-o["foo"] = 23;
-o["bar"] = false;
-o["baz"] = 3.141;
-
-// find an entry
-if (o.find("foo") != o.end()) {
- // there is an entry with key "foo"
-}
-
-// iterate the object
-for (json::iterator it = o.begin(); it != o.end(); ++it) {
- std::cout << it.key() << ':' << it.value() << '\n';
-}
-```
-
-### Conversion from STL containers
-
-Any sequence container (`std::array`, `std::vector`, `std::deque`, `std::forward_list`, `std::list`) whose values can be used to construct JSON types (e.g., integers, floating point numbers, Booleans, string types, or again STL containers described in this section) can be used to create a JSON array. The same holds for similar associative containers (`std::set`, `std::multiset`, `std::unordered_set`, `std::unordered_multiset`), but in these cases the order of the elements of the array depends how the elements are ordered in the respective STL container.
-
-```cpp
-std::vector<int> c_vector {1, 2, 3, 4};
-json j_vec(c_vector);
-// [1, 2, 3, 4]
-
-std::deque<float> c_deque {1.2, 2.3, 3.4, 5.6};
-json j_deque(c_deque);
-// [1.2, 2.3, 3.4, 5.6]
-
-std::list<bool> c_list {true, true, false, true};
-json j_list(c_list);
-// [true, true, false, true]
-
-std::forward_list<int64_t> c_flist {12345678909876, 23456789098765, 34567890987654, 45678909876543};
-json j_flist(c_flist);
-// [12345678909876, 23456789098765, 34567890987654, 45678909876543]
-
-std::array<unsigned long, 4> c_array {{1, 2, 3, 4}};
-json j_array(c_array);
-// [1, 2, 3, 4]
-
-std::set<std::string> c_set {"one", "two", "three", "four", "one"};
-json j_set(c_set); // only one entry for "one" is used
-// ["four", "one", "three", "two"]
-
-std::unordered_set<std::string> c_uset {"one", "two", "three", "four", "one"};
-json j_uset(c_uset); // only one entry for "one" is used
-// maybe ["two", "three", "four", "one"]
-
-std::multiset<std::string> c_mset {"one", "two", "one", "four"};
-json j_mset(c_mset); // only one entry for "one" is used
-// maybe ["one", "two", "four"]
-
-std::unordered_multiset<std::string> c_umset {"one", "two", "one", "four"};
-json j_umset(c_umset); // both entries for "one" are used
-// maybe ["one", "two", "one", "four"]
-```
-
-Likewise, any associative key-value containers (`std::map`, `std::multimap`, `std::unordered_map`, `std::unordered_multimap`) whose keys are can construct an `std::string` and whose values can be used to construct JSON types (see examples above) can be used to to create a JSON object. Note that in case of multimaps only one key is used in the JSON object and the value depends on the internal order of the STL container.
-
-```cpp
-std::map<std::string, int> c_map { {"one", 1}, {"two", 2}, {"three", 3} };
-json j_map(c_map);
-// {"one": 1, "two": 2, "three": 3}
-
-std::unordered_map<const char*, float> c_umap { {"one", 1.2}, {"two", 2.3}, {"three", 3.4} };
-json j_umap(c_umap);
-// {"one": 1.2, "two": 2.3, "three": 3.4}
-
-std::multimap<std::string, bool> c_mmap { {"one", true}, {"two", true}, {"three", false}, {"three", true} };
-json j_mmap(c_mmap); // only one entry for key "three" is used
-// maybe {"one": true, "two": true, "three": true}
-
-std::unordered_multimap<std::string, bool> c_ummap { {"one", true}, {"two", true}, {"three", false}, {"three", true} };
-json j_ummap(c_ummap); // only one entry for key "three" is used
-// maybe {"one": true, "two": true, "three": true}
-```
-
-### Implicit conversions
-
-The type of the JSON object is determined automatically by the expression to store. Likewise, the stored value is implicitly converted.
-
-```cpp
-/// strings
-std::string s1 = "Hello, world!";
-json js = s1;
-std::string s2 = js;
-
-// Booleans
-bool b1 = true;
-json jb = b1;
-bool b2 = jb;
-
-// numbers
-int i = 42;
-json jn = i;
-double f = jn;
-
-// etc.
-```
-
-You can also explicitly ask for the value:
-
-```cpp
-std::string vs = js.get<std::string>();
-bool vb = jb.get<bool>();
-int vi = jn.get<int>();
-
-// etc.
-```

-## Thanks
-
-I deeply appreciate the help of the following people.
-
-- [Teemperor](https://github.com/Teemperor) implemented CMake support and lcov integration, realized escape and Unicode handling in the string parser, and fixed the JSON serialization.
-- [elliotgoodrich](https://github.com/elliotgoodrich) fixed an issue with double deletion in the iterator classes.
-- [kirkshoop](https://github.com/kirkshoop) made the iterators of the class composable to other libraries.
-- [wancw](https://github.com/wanwc) fixed a bug that hindered the class to compile with Clang.
-- Tomas Åblad found a bug in the iterator implementation.
-
-Thanks a lot for helping out!
-
-## Execute unit tests with CMake
-
-To compile and run the tests, you need to execute
-
-```sh
-$ cmake .
-$ make
-$ ctest
-```
-
-If you want to generate a coverage report with the lcov/genhtml tools, execute this instead:
-
-```sh
-$ cmake .
-$ make coverage
-```
-
-**Note: You need to use GCC for now as otherwise the target coverage doesn't exist!**
-
-The report is now in the subfolder coverage/index.html
-
-## Execute unit tests with automake
-
-To compile the unit tests, you need to execute
-
-```sh
-$ autoreconf -i
-$ ./configure
-$ make
-```
-
-The unit tests can then be executed with
-
-```sh
-$ ./json_unit
-
-===============================================================================
-All tests passed (887 assertions in 10 test cases)
-```
-

-# Reference
-
-## Nomenclature
-
-We use the term "JSON" when we mean the [JavaScript Object Notation](http://json.org); that is, the file format. When we talk about the class implementing our library, we use "`json`" (typewriter font). Instances of this class are called "`json` values" to differentiate them from "JSON objects"; that is, unordered mappings, hashes, and whatnot.
-
-## Types and default values
-
-This table describes how JSON values are mapped to C++ types.
-
-| JSON type | value_type | C++ type | type alias | default value |
-| ----------------------- | -------------------------- | ----------------------------- | ---------------------- | --------------
-| null | `value_type::null` | `nullptr_t` | - | `nullptr` |
-| string | `value_type::string` | `std::string` | `json::string_t` | `""` |
-| number (integer) | `value_type::number` | `int` | `json::number_t` | `0` |
-| number (floating point) | `value_type::number_float` | `double` | `json::number_float_t` | `0.0` |
-| array | `value_type::array ` | `std::array<json>` | `json::array_t` | `{}` |
-| object | `value_type::object` | `std::map<std::string, json>` | `json::object_t` | `{}` |
-
-The second column list entries of an enumeration `value_type` which can be queried by calling `type()` on a `json` value. The column "C++ types" list the internal type that is used to represent the respective JSON value. The "type alias" column furthermore lists type aliases that are used in the `json` class to allow for more flexibility. The last column list the default value; that is, the value that is set if none is passed to the constructor or that is set if `clear()` is called.
-
-## Type conversions
-
-There are only a few type conversions possible:
-
-- An integer number can be translated to a floating point number.
-- A floating point number can be translated to an integer number. Note the number is truncated and not rounded, ceiled or floored.
-- Any value (i.e., boolean, string, number, null) but JSON objects can be translated into an array. The result is a singleton array that consists of the value before.
-- Any other conversion will throw a `std::logic_error` exception.
-
-When compatible, `json` values **implicitly convert** to `std::string`, `int`, `double`, `json::array_t`, and `json::object_t`. Furthermore, **explicit type conversion** is possible using the `get<>()` function with the aforementioned types.
-
-## Initialization
-
-`json` values can be created from many literals and variable types:
-
-| JSON type | literal/variable types | examples |
-| --------- | ---------------------- | -------- |
-| none | null pointer literal, `nullptr_t` type, no value | `nullptr` |
-| boolean | boolean literals, `bool` type, `json::boolean_t` type | `true`, `false` |
-| string | string literal, `char*` type, `std::string` type, `std::string&&` rvalue reference, `json::string_t` type | `"Hello"` |
-| number (integer) | integer literal, `short int` type, `int` type, `json_number_t` type | `42` |
-| number (floating point) | floating point literal, `float` type, `double` type, `json::number_float_t` type | `3.141529`
-| array | initializer list whose elements are `json` values (or can be translated into `json` values using the rules above), `std::vector<json>` type, `json::array_t` type, `json::array_t&&` rvalue reference | `{1, 2, 3, true, "foo"}` |
-| object | initializer list whose elements are pairs of a string literal and a `json` value (or can be translated into `json` values using the rules above), `std::map<std::string, json>` type, `json::object_t` type, `json::object_t&&` rvalue reference | `{ {"key1", 42}, {"key2", false} }` |
-
-## Number types
-
-[](http://json.org)
-
-The JSON specification explicitly does not define an internal number representation, but only the syntax of how numbers can be written down. Consequently, we would need to use the largest possible floating point number format (e.g., `long double`) to internally store JSON numbers.
-
-However, this would be a waste of space, so we let the JSON parser decide which format to use: If the number can be precisely stored in an `int`, we use an `int` to store it. However, if it is a floating point number, we use `double` to store it.

-@brief JSON for Modern C++
-
-The size of a JSON object is 16 bytes: 8 bytes for the value union whose
-largest item is a pointer type and another 8 byte for an element of the
-type union. The latter only needs 1 byte - the remaining 7 bytes are wasted
-due to alignment.
-
-@see http://stackoverflow.com/questions/7758580/writing-your-own-stl-container/7759622#7759622
-
-@bug Numbers are currently handled too generously. There are several formats
- that are forbidden by the standard, but are accepted by the parser.
-
-@todo Implement json::insert(), json::emplace(), json::emplace_back, json::erase

-This function is a bit tricky as it uses an initializer list of JSON objects

-to a list of JSON objects. The only difference is that in case of an object,
-the list will contain JSON array objects with two elements - one for the key
-and one for the value. As a result, it is sufficient to check if each element
-of the initializer list is an array (1) with two elements (2) whose first
-element is of type string (3). If this is the case, we treat the whole
-initializer list as list of pairs to construct an object. If not, we pass it
-as is to create an array.
