Function Documentation

json_array_get()

CT_JSON_API json_t* json_array_get	(	const json_t *	json,
		size_t	index
	)

get an array element by index

Parameters

json	the array to get the element from
index	the index of the element to get

Returns

the element at the index

Definition at line 28 of file json.c.

json_kind_name()

CT_JSON_API const char* json_kind_name

(

json_kind_t

kind

)

get the name of a json kind

Parameters

kind	the kind to get the name of

Returns

the name of the kind

Definition at line 16 of file ast.c.

json_map_get()

CT_JSON_API json_t* json_map_get	(	const json_t *	json,
		const char *	key
	)

get a json value from an object by key

Parameters

json	the object to get the value from
key	the key to get the value of

Returns

the value of the key

Definition at line 17 of file json.c.

json_parse()

CT_JSON_API json_parse_t json_parse	(	io_t *	io,
		logger_t *	logger,
		arena_t *	arena
	)

parse an io into a json value parse the contents of an io object into a json value

Note

if the parse fails, the logger will contain error information

Parameters

io	the io to parse
logger	the logger to report errors to
arena	the arena to use

Returns

the parse result

pretty print a json value to an io

Parameters

json	the json value to print
io	the io to print to
indent	the number of spaces to indent, or 0 for compact printing
tabs	if true, use tabs instead of spaces

json_scan()

CT_JSON_API json_t* json_scan	(	io_t *	io,
		logger_t *	logger,
		arena_t *	arena
	)

scan an io into a json value scan the contents of an io object into a json value

Note

if the scan fails, the logger will contain error information

Parameters

io	the io to scan
logger	the logger to report errors to
