晋太元中，武陵人捕鱼为业。缘溪行，忘路之远近。忽逢桃花林，夹岸数百步，中无杂树，芳草鲜美，落英缤纷。渔人甚异之，复前行，欲穷其林。 　　林尽水源，便得一山，山有小口，仿佛若有光。便舍船，从口入。初极狭，才通人。复行数十步，豁然开朗。土地平旷，屋舍俨然，有良田、美池、桑竹之属。阡陌交通，鸡犬相闻。其中往来种作，男女衣着，悉如外人。黄发垂髫，并怡然自乐。 　　见渔人，乃大惊，问所从来。具答之。便要还家，设酒杀鸡作食。村中闻有此人，咸来问讯。自云先世避秦时乱，率妻子邑人来此绝境，不复出焉，遂与外人间隔。问今是何世，乃不知有汉，无论魏晋。此人一一为具言所闻，皆叹惋。余人各复延至其家，皆出酒食。停数日，辞去。此中人语云：“不足为外人道也。”(间隔 一作：隔绝) 　　既出，得其船，便扶向路，处处志之。及郡下，诣太守，说如此。太守即遣人随其往，寻向所志，遂迷，不复得路。 　　南阳刘子骥，高尚士也，闻之，欣然规往。未果，寻病终。后遂无问津者。 .

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,
