[ANN] luajson 0.9 released

[Thomas Harning <harningt@...>]

I just released luajson 0.9 on LuaForge [1] with its source repository  
on repo.or.cz [2].  In short it's a customizable JSON parser/encoder  
for Lua.  Licensed under MIT-style license.

It uses LPEG for the parser portion which makes it highly customizable  
AND fast.

Basic featureset:
 * Supports decoding JSON w/ varying dialect strictness.
   * NaN/Infinite, null, undefined, being allowed or not
   * Hex digit support
   * How to handle unknown escape sequences (pass-through character  
or abort)
 * Supports encoding non-recursive Lua tables, and attempts to  
reconcile whether a table is array or not
 * Handle null and undefined values in custom ways... use actual  
'nil' or constants for round-tripping

Future items:
 * Handle custom 'function' calls to process values
 * Handle custom encoding items (such as to round-trip a function  
call element)
 * Custom encoding mechanisms
 * Integration with proper/custom unicode handler
 * Luarocks spec

Items that could use help:
 * Best way to build output text
 * Best way to handle unicode
 * Best way to handle the null/undefined values
 * Best way to detect/mark arrays vs objects at encoding/decoding-point
