mrhill/json-parser

Very low footprint JSON parser written in portable ANSI C

Very low footprint JSON parser written in portable ANSI C.

• BSD licensed with no dependencies (i.e. just drop the C file into your project)
• Never recurses or allocates more memory than it needs
• Very simple API with operator sugar for C++

Installing

There is now a makefile which will produce a libjsonparser static and dynamic library. However, this is not required to build json-parser, and the source files (json.c and json.h) should be happy in any build system you already have in place.

API

json_value * json_value_dup (json_value const *);

void json_value_dump (FILE * fp, json_value const * v);

json_value * json_parse (const json_char * json,
                         size_t length);

json_value * json_parse_ex (json_settings * settings,
                            const json_char * json,
                            size_t length,
                            char * error);

void json_value_free (json_value *);

The type field of json_value is one of:

• json_object (see u.object.length, u.object.values[x].name, u.object.values[x].value)
• json_array (see u.array.length, u.array.values)
• json_integer (see u.integer)
• json_double (see u.dbl)
• json_string (see u.string.ptr, u.string.length)
• json_boolean (see u.boolean)
• json_null
