NAME
       json - JSON parser


SYNOPSIS
       package require Tcl  8.4

       package require json  ?1.1.2?

       ::json::json2dict txt

_________________________________________________________________


DESCRIPTION
       The  json  package  provides  a  simple  Tcl-only  library for parsing the JSON http://www.json.org/ data
       exchange format as specified in RFC 4627 http://www.ietf.org/rfc/rfc4627.txt.  There is some ambiguity in
       parsing  JSON  because  JSON has type information that is not maintained by the Tcl conversion.  The json
       package returns data as a Tcl dict.  Either the dict package or Tcl 8.5 is required for use.


COMMANDS
       ::json::json2dict txt
              Parse JSON formatted text txt into a Tcl dict and return the value.


EXAMPLES
       An example of a JSON array converted to Tcl.  A JSON array is returned as a  single  item  with  multiple
       elements.
