NAME
       json - JSON parser

SYNOPSIS
       package require Tcl  8.4

       package require json  ?1.1?

       ::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  ambigu-ity ambiguity
       ity  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.
