-JSMN
-====
-
-jsmn (pronounced like 'jasmine') is a minimalistic JSON parser in C. It can be
-easily integrated into resource-limited or embedded projects.
-
-You can find more information about JSON format at [json.org][1]
-
-Library sources are available at https://github.com/zserge/jsmn
-
-The web page with some information about jsmn can be found at
-[http://zserge.com/jsmn.html][2]
-
-Philosophy
-----------
-
-Most JSON parsers offer you a bunch of functions to load JSON data, parse it
-and extract any value by its name. jsmn proves that checking the correctness of
-every JSON packet or allocating temporary objects to store parsed JSON fields
-often is an overkill.
-
-JSON format itself is extremely simple, so why should we complicate it?
-
-jsmn is designed to be **robust** (it should work fine even with erroneous
-data), **fast** (it should parse data on the fly), **portable** (no superfluous
-dependencies or non-standard C extensions). An of course, **simplicity** is a
-key feature - simple code style, simple algorithm, simple integration into
-other projects.
-
-Features
---------
-
-* compatible with C89
-* no dependencies (even libc!)
-* highly portable (tested on x86/amd64, ARM, AVR)
-* about 200 lines of code
-* extremely small code footprint
-* API contains only 2 functions
-* no dynamic memory allocation
-* incremental single-pass parsing
-* library code is covered with unit-tests
-
-Design
-------
-
-The rudimentary jsmn object is a **token**. Let's consider a JSON string:
-
- '{ "name" : "Jack", "age" : 27 }'
-
-It holds the following tokens:
-
-* Object: `{ "name" : "Jack", "age" : 27}` (the whole object)
-* Strings: `"name"`, `"Jack"`, `"age"` (keys and some values)
-* Number: `27`
-
-In jsmn, tokens do not hold any data, but point to token boundaries in JSON
-string instead. In the example above jsmn will create tokens like: Object
-[0..31], String [3..7], String [12..16], String [20..23], Number [27..29].
-
-Every jsmn token has a type, which indicates the type of corresponding JSON
-token. jsmn supports the following token types:
-
-* Object - a container of key-value pairs, e.g.:
- `{ "foo":"bar", "x":0.3 }`
-* Array - a sequence of values, e.g.:
- `[ 1, 2, 3 ]`
-* String - a quoted sequence of chars, e.g.: `"foo"`
-* Primitive - a number, a boolean (`true`, `false`) or `null`
-
-Besides start/end positions, jsmn tokens for complex types (like arrays
-or objects) also contain a number of child items, so you can easily follow
-object hierarchy.
-
-This approach provides enough information for parsing any JSON data and makes
-it possible to use zero-copy techniques.
-
-Install
--------
-
-To clone the repository you should have Git installed. Just run:
-
- $ git clone https://github.com/zserge/jsmn
-
-Repository layout is simple: jsmn.c and jsmn.h are library files, tests are in
-the jsmn\_test.c, you will also find README, LICENSE and Makefile files inside.
-
-To build the library, run `make`. It is also recommended to run `make test`.
-Let me know, if some tests fail.
-
-If build was successful, you should get a `libjsmn.a` library.
-The header file you should include is called `"jsmn.h"`.
-
-API
----
-
-Token types are described by `jsmntype_t`:
-
- typedef enum {
- JSMN_PRIMITIVE = 0,
- JSMN_OBJECT = 1,
- JSMN_ARRAY = 2,
- JSMN_STRING = 3
- } jsmntype_t;
-
-**Note:** Unlike JSON data types, primitive tokens are not divided into
-numbers, booleans and null, because one can easily tell the type using the
-first character:
-
-* <code>'t', 'f'</code> - boolean
-* <code>'n'</code> - null
-* <code>'-', '0'..'9'</code> - number
-
-Token is an object of `jsmntok_t` type:
-
- typedef struct {
- jsmntype_t type; // Token type
- int start; // Token start position
- int end; // Token end position
- int size; // Number of child (nested) tokens
- } jsmntok_t;
-
-**Note:** string tokens point to the first character after
-the opening quote and the previous symbol before final quote. This was made
-to simplify string extraction from JSON data.
-
-All job is done by `jsmn_parser` object. You can initialize a new parser using:
-
- jsmn_parser parser;
- jsmntok_t tokens[10];
-
- jsmn_init(&parser);
-
- // js - pointer to JSON string
- // tokens - an array of tokens available
- // 10 - number of tokens available
- jsmn_parse(&parser, js, tokens, 10);
-
-This will create a parser, and then it tries to parse up to 10 JSON tokens from
-the `js` string.
-
-A non-negative reutrn value of `jsmn_parse` is the number of tokens actually
-used by the parser.
-Passing NULL instead of the tokens array would not store parsing results, but
-instead the function will return the value of tokens needed to parse the given
-string. This can be useful if you don't know yet how many tokens to allocate.
-
-If something goes wrong, you will get an error. Error will be one of these:
-
-* `JSMN_ERROR_INVAL` - bad token, JSON string is corrupted
-* `JSMN_ERROR_NOMEM` - not enough tokens, JSON string is too large
-* `JSMN_ERROR_PART` - JSON string is too short, expecting more JSON data
-
-If you get `JSON_ERROR_NOMEM`, you can re-allocate more tokens and call
-`jsmn_parse` once more. If you read json data from the stream, you can
-periodically call `jsmn_parse` and check if return value is `JSON_ERROR_PART`.
-You will get this error until you reach the end of JSON data.
