HomeSYNOPSIS
schema = table.fromJsonSchema(text)
DESCRIPTION
This is a companion function to table.toJson().
Decodes a JSON formatted schema description into a lua table. The resulting table can be stored and used with table.toJson() to generate JSON data.
The decoder works almost identical to table.fromJson(). The only difference is when a JSON object with the name properties is encountered. The decoder will decode this into a Lua array instead of a name=value table.
RETURN VALUE
On success, returns a lua table with the decoded schema.
On failure, returns two values: nil and the index into the string where the first error was encountered.
