Short story (If you already have ruby and cmake):
./configure && make install
When things go wrong:
attain CMake (http://www.cmake.org) and ruby (http://ruby-lang.org) and
try again.
OR, attain CMake and build by hand:
1. mkdir build
2. cd build
3. cmake ..
4. make
5. build output left in yajl-X.Y.Z
NOTE: for 64-bit systems where lib64 is used you can pass the cmake
variable LIB_SUFFIX to cause installation into the system's 'lib64'
directory.

YAJL has been successfully built using Visual Studio 8. CMake, a
build file generator, is used to build the software. CMake supports
several different build environments, so you may either build YAJL
using the IDE via the following steps:
1. acquire cmake (http://www.cmake.org)
2. mkdir build
3. cd build
4. cmake ..
5. devenv YetAnotherJSONParser.sln /project ALL_BUILD /build Release
6. build output is left in build/yajl-X.Y.Z
Or you can build from the command line using nmake:
1. Click Start > Programs > Microsoft Visual Studio > Visual Studio
Tools > Visual Studio Command Prompt -- for your version of Visual
Studio, which will open a command prompt. You may verify that the
compiler is in your path by typing "cl /?" at the prompt.
2. cd C:\path\to\yajl\source\
3. mkdir build
4. cd build
5. cmake -G"NMake Makefiles" -DCMAKE_BUILD_TYPE=Release ..
6. nmake
7. nmake install
Earlier versions of visual studio and other build generators haven't
been thoroughly tested, but should work without any major issues.

contributed by Artem S Vybornov.
* lth add #ifdef __cplusplus wrappers to yajl_tree to allow proper
usage from many populer C++ compilers.
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 - various win32 fixes, including build documentation improvements

* lth & vitali - allow builder to specify alternate lib directory
for installation (i.e. lib64)
* Vitali Lovich - yajl version number now programatically accessible

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

**********************************************************************
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 were 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

/* 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
