+JSMN
+====
+
+[![Build Status](https://travis-ci.org/zserge/jsmn.svg?branch=master)](https://travis-ci.org/zserge/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). And 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.
+
+Usage
+-----
+
+Download `jsmn.h`, include it, done.
+
+```
+#include "jsmn.h"
+
+...
+jsmn_parser p;
+jsmntok_t t[128]; /* We expect no more than 128 JSON tokens */
+
+jsmn_init(&p);
+r = jsmn_parse(&p, s, strlen(s), t, 128);
+```
+
+Since jsmn is a single-header, header-only library, for more complex use cases
+you might need to define additional macros. `#define JSMN_STATIC` hides all
+jsmn API symbols by making them static. Also, if you want to include `jsmn.h`
+from multiple C files, to avoid duplication of symbols you may define  `JSMN_HEADER` macro.
+
+```
+/* In every .c file that uses jsmn include only declarations: */
+#define JSMN_HEADER
+#include "jsmn.h"
+
+/* Additionally, create one jsmn.c file for jsmn implementation: */
+#include "jsmn.h"
+```
+
+API
+---
+
+Token types are described by `jsmntype_t`:
+
+	typedef enum {
+		JSMN_UNDEFINED = 0,
+		JSMN_OBJECT = 1,
+		JSMN_ARRAY = 2,
+		JSMN_STRING = 3,
+		JSMN_PRIMITIVE = 4
+	} 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, strlen(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 return 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 `JSMN_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 `JSMN_ERROR_PART`.
+You will get this error until you reach the end of JSON data.
