This is an OCaml library which reads and writes data in the JSON format (JavaScript Object Notation). This format can be used as a light-weight replacement for XML. Visit http://www.json.org for more information about JSON. The documentation for this library is located at http://martin.jambon.free.fr/json-wheel/ Installation ============ Requirements: - OCaml - GNU make - the findlib library manager (ocamlfind command) - the netstring library From the source directory, do: make make install If you want to remove the package do: make uninstall Standard compliance =================== The JSON parser, in the default mode, conforms to the specifications of RFC 4627, with only some limitations due to the implementation of the corresponding OCaml types: * ints that are too large to be represented with the OCaml int type cause an error. The limit depends whether it is a 32-bit or 64-bit platform (see min_int and max_int). * floats may be represented with reduced precision as they must fit into the 8 bytes of the "double" format. * The size of OCaml strings is limited to about 16MB on 32-bit platforms, and much more on 64-bit platforms (see Sys.max_string_length). RFC 4627: http://www.ietf.org/rfc/rfc4627.txt?number=4627 The UTF-8 encoding is supported, however no attempt is made at checking whether strings are actually valid UTF-8 or not. Therefore, other ASCII-compatible encodings such as the ISO 8859 series are supported as well. Tests ===== Json.org provides a test suite. You can download the file (test.zip), unzip it in the parent directory, and run "make test". Look for ERROR messages, which indicate that a file that should fail actually passes or that a file that should pass fails the test. ../test/fail18.json doesn't pass: this is only because an int which is too large for the OCaml int type on a 32-bit platform. ../test/fail18.json passes: it is marked as "should fail" because is has a high number of nesting. Although the standard allows such restrictions, there are not mandatory at all. Our parser does not have such a restriction.
