The old performance article for RapidJSON 0.1 is provided [here](https://code.google.com/p/rapidjson/wiki/Performance).
This file will be updated with new version and better procedures.
The (third-party) performance tests have been removed from this repository
and are now part of a dedicated [native JSON benchmark collection] [1].
In the meantime, you may also refer to the following third-party benchmarks.
This file will be updated with a summary of benchmarking results based on
the above benchmark collection in the future.

* Introduction:
=============
JSON (JavaScript Object Notation) is a lightweight data-interchange format.
It can represent integer, real number, string, an ordered sequence of
value, and a collection of name/value pairs.
JsonCpp is a simple API to manipulate JSON value, handle serialization
and unserialization to string.
It can also preserve existing comment in unserialization/serialization steps,
making it a convenient format to store user input files.
Unserialization parsing is user friendly and provides precise error reports.
* Building/Testing:
=================
JsonCpp uses Scons (http://www.scons.org) as a build system. Scons requires
python to be installed (http://www.python.org).
You download scons-local distribution from the following url:
http://sourceforge.net/project/showfiles.php?group_id=30337&package_id=67375
Unzip it in the directory where you found this README file. scons.py Should be
at the same level as README.
python scons.py platform=PLTFRM [TARGET]
where PLTFRM may be one of:
suncc Sun C++ (Solaris)
vacpp Visual Age C++ (AIX)
mingw
msvc6 Microsoft Visual Studio 6 service pack 5-6
msvc70 Microsoft Visual Studio 2002
msvc71 Microsoft Visual Studio 2003
msvc80 Microsoft Visual Studio 2005
linux-gcc Gnu C++ (linux, also reported to work for Mac OS X)
adding platform is fairly simple. You need to change the Sconstruct file
to do so.
and TARGET may be:
check: build library and run unit tests.
* Running the test manually:
==========================
cd test
# This will run the Reader/Writer tests
python runjsontests.py "path to jsontest.exe"
# This will run the Reader/Writer tests, using JSONChecker test suite
# (http://www.json.org/JSON_checker/).
# Notes: not all tests pass: JsonCpp is too lenient (for example,
# it allows an integer to start with '0'). The goal is to improve
# strict mode parsing to get all tests to pass.
python runjsontests.py --with-json-checker "path to jsontest.exe"
# This will run the unit tests (mostly Value)
python rununittests.py "path to test_lib_json.exe"
You can run the tests using valgrind:
python rununittests.py --valgrind "path to test_lib_json.exe"
* Building the documentation:
===========================
Run the python script doxybuild.py from the top directory:
python doxybuild.py --open --with-dot
See doxybuild.py --help for options.
* Adding a reader/writer test:
============================
To add a test, you need to create two files in test/data:
- a TESTNAME.json file, that contains the input document in JSON format.
- a TESTNAME.expected file, that contains a flatened representation of
the input document.
TESTNAME.expected file format:
- each line represents a JSON element of the element tree represented
by the input document.
- each line has two parts: the path to access the element separated from
the element value by '='. Array and object values are always empty
(e.g. represented by either [] or {}).
- element path: '.' represented the root element, and is used to separate
object members. [N] is used to specify the value of an array element
at index N.
See test_complex_01.json and test_complex_01.expected to better understand
element path.
* Understanding reader/writer test output:
========================================
When a test is run, output files are generated aside the input test files.
Below is a short description of the content of each file:
- test_complex_01.json: input JSON document
- test_complex_01.expected: flattened JSON element tree used to check if
parsing was corrected.
- test_complex_01.actual: flattened JSON element tree produced by
jsontest.exe from reading test_complex_01.json
- test_complex_01.rewrite: JSON document written by jsontest.exe using the
Json::Value parsed from test_complex_01.json and serialized using
Json::StyledWritter.
- test_complex_01.actual-rewrite: flattened JSON element tree produced by
jsontest.exe from reading test_complex_01.rewrite.
test_complex_01.process-output: jsontest.exe output, typically useful to
understand parsing error.

UltraJSON is a fast and extendable JSON encoder and decoder written in pure C
Python bindings are available as the module ujson (through easy_install / pypi):
http://pypi.python.org/pypi/ujson/
Installation instructions:
1. Build and install ujson Python extension (requires root)
Go to <root>/python
Type: python setup.py build install
2. Run tests (as needed)
Type: python tests.py
Same instructions applies for Windows except that step 1) isn't necessary since
a prebuilt static library is included.

Arguments:

enc - Function definitions for querying JSOBJ type
buffer - Preallocated buffer to store result in. If NULL function allocates own buffer
cbBuffer - Length of buffer (ignored if buffer is NULL)
Returns:
Encoded JSON object as a null terminated char string.
NOTE:
If the supplied buffer wasn't enough to hold the result the function will allocate a new buffer.
Life cycle of the provided buffer must still be handled by caller.
If the return value doesn't equal the specified buffer caller must release the memory using

2.0.1
* lth generator flag to allow client to specify they want
escaped solidi '/'. issue #28
* lth crash fix when yajl_parse() is never called. issue #27
2.0.0
* lth YAJL is now ISC licensed: http://en.wikipedia.org/wiki/ISC_license
* lth 20-35% (osx and linux respectively) parsing performance
improvement attained by tweaking string scanning (idea: @michaelrhanson).
* Florian Forster & lth - yajl_tree interface introduced as a higher level
interface to the parser (eats JSON, poops a memory representation)
* lth require a C99 compiler
* lth integers are now represented with long long (64bit+) on all platforms.
* lth size_t now used throughout to represent buffer lengths, so you can
safely manage buffers greater than 4GB.
* gno semantic improvements to yajl's API regarding partial value parsing and
trailing garbage
* lth new configuration mechanism for yajl, see yajl_config() and
yajl_gen_config()
* gno more allocation checking in more places
* gno remove usage of strtol, replace with custom implementation that cares
not about your locale.
* lth yajl_parse_complete renamed to yajl_complete_parse.
* lth add a switch to validate utf8 strings as they are generated.
* lth tests are a lot quieter in their output.
* lth addition of a little in tree performance benchmark, `perftest` in
perf/perftest.c
1.0.12
* Conrad Irwin - Parse null bytes correctly
* Mirek Rusin - fix LLVM warnings
* gno - Don't generate numbers for keys. closes #13
* lth - various win32 fixes, including build documentation improvements
* John Stamp - Don't export private symbols.
* John Stamp - Install yajl_version.h, not the template.
* John Stamp - Don't use -fPIC for static lib. Cmake will automatically add it for the shared.

* lth & vitali - allow builder to specify alternate lib directory
for installation (i.e. lib64)
* Vitali Lovich - yajl version number now programatically accessible
* lth - prevent cmake from embedding rpaths in binaries. Static linking
makes this unneccesary.
1.0.9
* lth - fix inverted logic causing yajl_gen_double() to always fail on
win32 (thanks to Fredrik Kihlander for the report)
1.0.8
* Randall E. Barker - move dllexport defnitions so dlls with proper
exports can again be generated on windows
* lth - add yajl_get_bytes_consumed() which allows the client to
determine the offset as an error, as well as determine how
many bytes of an input buffer were consumed.
* lth - fixes to keep "error offset" up to date (like when the
client callback returns 0)
* Brian Maher - allow client to specify a printing function in
generation
1.0.7
* lth fix win32 build (isinf and isnan)
1.0.6
* lth fix several compiler warnings
* lth fix generation of invalid json from yajl_gen_double
(NaN is not JSON)

contribution.
* lth client may override allocation routines at generator or parser
allocation time
* tjw add yajl_parse_complete routine to allow client to explicitly
specify end-of-input, solving the "lonely number" case, where
json text consists only of an element with no explicit syntactic
end.

* tjw cleanup of code for symmetry and ease of reading
* lth integration of patches from Robert Varga which cleanup
compilation warnings on 64 bit linux
0.4.0

Eric Bergstrome
* lth yajl_number callback to allow passthrough of arbitrary precision
numbers to client. Thanks to Hatem Nassrat.
* lth yajl_integer now deals in long, instead of long long. This
combined with yajl_number improves compiler compatibility while
maintaining precision.
* lth better ./configure && make experience (still requires cmake and
ruby)

**********************************************************************
This is YAJL 2, for the legacy version of YAJL. see
https://github.com/lloyd/yajl/tree/1.x
**********************************************************************
Welcome to Yet Another JSON Library (YAJL)
## Why does the world need another C library for parsing JSON?
Good question. In a review of current C JSON parsing libraries I was
unable to find one that satisfies my requirements. Those are,
0. written in C
1. portable
2. robust -- as close to "crash proof" as possible
3. data representation independent
4. fast
5. generates verbose, useful error messages including context of where
the error occurs in the input text.
6. can parse JSON data off a stream, incrementally
7. simple to use
8. tiny
Numbers 3, 5, 6, and 7 where particularly hard to find, and were what
caused me to ultimately create YAJL. This document is a tour of some
of the more important aspects of YAJL.
## YAJL is Free.
Permissive licensing means you can use it in open source and
commercial products alike without any fees. My request beyond the
licensing is that if you find bugs drop me a email, or better yet,
fork and fix.
Porting YAJL should be trivial, the implementation is ANSI C. If you
port to new systems I'd love to hear of it and integrate your patches.
## YAJL is data representation independent.
BYODR! Many JSON libraries impose a structure based data representation
on you. This is a benefit in some cases and a drawback in others.
YAJL uses callbacks to remain agnostic of the in-memory representation.
So if you wish to build up an in-memory representation, you may do so
using YAJL, but you must bring the code that defines and populates the
in memory structure.
This also means that YAJL can be used by other (higher level) JSON
libraries if so desired.
## YAJL supports stream parsing
This means you do not need to hold the whole JSON representation in
textual form in memory. This makes YAJL ideal for filtering projects,
where you're converting YAJL from one form to another (i.e. XML). The
included JSON pretty printer is an example of such a filter program.
## YAJL is fast
Minimal memory copying is performed. YAJL, when possible, returns
pointers into the client provided text (i.e. for strings that have no
embedded escape chars, hopefully the common case). I've put a lot of
effort into profiling and tuning performance, but I have ignored a
couple possible performance improvements to keep the interface clean,
small, and flexible. My hope is that YAJL will perform comparably to
the fastest JSON parser out there.
YAJL should impose both minimal CPU and memory requirements on your
application.
## YAJL is tiny.
Fat free. No whip.
enjoy,
Lloyd - July, 2007

\mainpage Yet Another JSON Library (YAJL)
\author Lloyd Hilaiel
\date 2007-2011
Yet Another JSON Library (YAJL) is a small event-driven (SAX-style)
JSON parser written in ANSI C, and a small validating JSON
generator. YAJL is released under the permissive ISC license.
\section features Features
-# Stream (incremental) parsing and generation of JSON
-# ANSI C
-# Human readable error messages with context
-# tiny
-# event driven
-# support for generating "beautified" JSON
-# includes
It also includes a small simplified tree interface for
simplified parsing and extraction of data from smallish JSON documents.
\section usage Usage
See <a href="reformatter_2json_reformat_8c-example.html">json_reformat.c</a> for a complete example of stream based parsing
and generation of JSON. See <a href="example_2parse_config_8c-example.html">parse_config.c</a> for an example of the
simplified tree interface.

/* Impact of the stream parsing feature on the lexer:
*
* YAJL support stream parsing. That is, the ability to parse the first
* bits of a chunk of JSON before the last bits are available (still on
* the network or disk). This makes the lexer more complex. The
* responsibility of the lexer is to handle transparently the case where
* a chunk boundary falls in the middle of a token. This is
* accomplished is via a buffer and a character reading abstraction.
*
* Overview of implementation
*
* When we lex to end of input string before end of token is hit, we
* copy all of the input text composing the token into our lexBuf.
*
* Every time we read a character, we do so through the readChar function.
* readChar's responsibility is to handle pulling all chars from the buffer
* before pulling chars from input text
