/*!
|
|
* If nothing is defined, the default definitions are JSMN_PARENT_LINKS and *
|
|
* JSMN_NEXT_SIBLING with a jsmntok field size of 4 bytes (unsigned int). *
|
|
* This will parse one json object in a buffer at a time and return after a *
|
|
* successful json object parse. To check if there is more data in the *
|
|
* buffer that hasn't been parsed, run jsmn_eof. !*/
|
|
|
|
/*! @def JSMN_PARENT_LINKS
|
|
* @brief Adds a parent field to the token
|
|
*
|
|
* This decreases the initial time required to parse a json buffer and
|
|
* simplifies the post-processing of token array by adding a link to the id of
|
|
* a token's parent.
|
|
* This is enabled by default and highly recommended.
|
|
*/
|
|
|
|
/*! @def JSMN_NEXT_SIBLING
|
|
* @brief Adds a next_sibling field to the token
|
|
*
|
|
* This simplifies the post-processing of token array by adding a link to the id
|
|
* of a token's next sibling.
|
|
* This is enabled by default and highly recommended.

|
|
|
|
/*! @def JSMN_UTF8
|
|
* @brief Add UTF-8 functionality
|
|
*
|
|
* This allows for stricter parsing of json strings and also allows for the
|
|
* conversion of escaped characters (\uXXXX) to UTF-8 and back.

|
/*! @def JSMN_LOW_MEMORY
|
|
* @brief Enables defintions that reduce jsmn's memory footprint for small
|
|
* devices and doesn't enable definitions that increase it's footprint.
|
|
*
|
|
* This enables definitions that reduce jsmn's memory footprint at the cost of
|
|
* CPU usage. This is useful for small devices that don't parse json objects
|
|
* often and have restrictive memory requirements.

/*! @def JSMN_SHORT_TOKENS
|
|
* @brief Changes the tokens field size from a uint32_t to a uint16_t
|
|
*
|
|
* This reduces the jsmntok size by half by changing jsmntok field sizes
|
|
* from an unsigned int to an unsigned short. NOTE: This reduces the maximum
|
|
* possible json string length from 4,294,967,295 to 65,535 minus the size of
|
|
* jsmnerr.

|
|
* JSMN_MULTIPLE_JSON

/*! @def JSMN_PERMISSIVE_PRIMITIVE
|
|
* @brief Allows PRIMITIVEs to be any contiguous value
|
|
*
|
|
* This allows PRIMIVITEs to be any contiguous value that does not contain a
|
|
* character that has a special meaning to json (`{}[]",:`). NOTE: There is no
|
|
* validation of JSMN_PRI_MINUS, JSNM_PRI_DECIMAL, or JSMN_PRI_EXPONENT;
|
|
* everything is the base type JSMN_PRIMITIVE.

/*! @def JSMN_MULTIPLE_JSON
|
|
* @brief Allows multiple json objects in a complete buffer
|
|
*
|
|
* This allows jsmn to parse multiple json objects in a single buffer.
|
|
* NOTE: If a single json object is malformed jsmn_parse will return with
|
|
* an error.
