The serializing counterpart to json-parser.

As with json-parser: BSD licensed, almost ANSI C89 apart from a single use of snprintf.

Quick example (docs coming soon):

json_value * arr = json_array_new(0); json_array_push(arr, json_string_new("Hello world!")); json_array_push(arr, json_integer_new(128)); char * buf = malloc(json_measure(arr)); json_serialize(buf, arr); printf("%s\n", buf);

[ "Hello world!", 128 ]

json-builder is fully interoperable with json-parser:

char json[] = "[ 1, 2, 3 ]"; json_settings settings = {}; settings.value_extra = json_builder_extra; /* space for json-builder state */ char error[128]; json_value * arr = json_parse_ex(&settings, json, strlen(json), error); /* Now serialize it again. */ char * buf = malloc(json_measure(arr)); json_serialize(buf, arr); printf("%s\n", buf);

[ 1, 2, 3 ]

Note that values created by or modified by json-builder must be freed with json_builder_free instead of json_value_free, otherwise the memory of the builder state will be leaked.

• json_serialize_mode_multiline — Generate multi-line JSON, for example:

[ 1, 2, 3 ]

• json_serialize_mode_single_line — Generate JSON on a single line, for example:

[ 1, 2, 3 ]

• json_serialize_mode_packed — Generate JSON as tightly packed as possible, for example:

[1,2,3]

• json_serialize_opt_CRLF — use CR/LF (Windows) line endings

• json_serialize_opt_pack_brackets — do not leave spaces around brackets (e.g. [ 1, 2 ] becomes [1, 2])

• json_serialize_opt_no_space_after_comma — do not leave spaces after commas

• json_serialize_opt_no_space_after_colon — do not leave spaces after colons (inside objects)

• json_serialize_opt_use_tabs — indent using tabs instead of spaces when in multi-line mode

• indent_size — the number of tabs or spaces to indent with in multi-line mode
