json_parser.erl is a parser for json documents.
The parser has a SAX-like API. It also has a mechanism to parse input data in blocks - if it reaches the end of the input data, it will call a function to provide the next block. The combination of these properties results in a parser that can input of arbitrary size, or a stream of data.
Included is a handler function that translates the SAX events into the same output format produced by mochijson2. Looks like this: {struct, [{<<"key1">>, <<"value1">>}, {<<"key2">>, 123}]}.
Interestingly, the new parser (sax parser combined with handler) is roughly 2x as fast as mochijson2 (On my PC, at least).
The parser consists of just 1 file, with some edoc documentation and a couple of very simple examples
included. It only works on UTF-8 encoded input (which implies that it can also parse ASCII, of course).
It can be redistributed under the terms of the GNU Lesser General Public License.
