+--

+-- DECODING (from a JSON string to a Lua table)
+--
+--
+--   JSON = assert(loadfile "JSON.lua")() -- one-time load of the routines
+--
+--   local lua_value = JSON:decode(raw_json_text)
+--
+--   If the JSON text is for an object or an array, e.g.
+--     { "what": "books", "count": 3 }
+--   or
+--     [ "Larry", "Curly", "Moe" ]
+--
+--   the result is a Lua table, e.g.
+--     { what = "books", count = 3 }
+--   or
+--     { "Larry", "Curly", "Moe" }
+--
+--
+--   The encode and decode routines accept an optional second argument,
+--   "etc", which is not used during encoding or decoding, but upon error
+--   is passed along to error handlers. It can be of any type (including nil).
+--
+--
+--
+-- ERROR HANDLING
+--
+--   With most errors during decoding, this code calls
+--
+--      JSON:onDecodeError(message, text, location, etc)
+--
+--   with a message about the error, and if known, the JSON text being
+--   parsed and the byte count where the problem was discovered. You can
+--   replace the default JSON:onDecodeError() with your own function.
+--
+--   The default onDecodeError() merely augments the message with data
+--   about the text and the location if known (and if a second 'etc'
+--   argument had been provided to decode(), its value is tacked onto the
+--   message as well), and then calls JSON.assert(), which itself defaults
+--   to Lua's built-in assert(), and can also be overridden.
+--
+--   For example, in an Adobe Lightroom plugin, you might use something like
+--
+--          function JSON:onDecodeError(message, text, location, etc)
+--             LrErrors.throwUserError("Internal Error: invalid JSON data")
+--          end
+--
+--   or even just
+--
+--          function JSON.assert(message)
+--             LrErrors.throwUserError("Internal Error: " .. message)
+--          end
+--
+--   If JSON:decode() is passed a nil, this is called instead:
+--
+--      JSON:onDecodeOfNilError(message, nil, nil, etc)
+--
+--   and if JSON:decode() is passed HTML instead of JSON, this is called:
+--
+--      JSON:onDecodeOfHTMLError(message, text, nil, etc)
+--
+--   The use of the fourth 'etc' argument allows stronger coordination
+--   between decoding and error reporting, especially when you provide your
+--   own error-handling routines. Continuing with the the Adobe Lightroom
+--   plugin example:
+--
+--          function JSON:onDecodeError(message, text, location, etc)
+--             local note = "Internal Error: invalid JSON data"
+--             if type(etc) = 'table' and etc.photo then
+--                note = note .. " while processing for " .. etc.photo:getFormattedMetadata('fileName')
+--             end
+--             LrErrors.throwUserError(note)
+--          end
+--
+--            :
+--            :
+--
+--          for i, photo in ipairs(photosToProcess) do
+--               :             
+--               :             
+--               local data = JSON:decode(someJsonText, { photo = photo })
+--               :             
+--               :             
+--          end
+--
+--
+--
+--
+--
+-- DECODING AND STRICT TYPES
+--
+--   Because both JSON objects and JSON arrays are converted to Lua tables,
+--   it's not normally possible to tell which original JSON type a
+--   particular Lua table was derived from, or guarantee decode-encode
+--   round-trip equivalency.
+--
+--   However, if you enable strictTypes, e.g.
+--
+--      JSON = assert(loadfile "JSON.lua")() --load the routines
+--      JSON.strictTypes = true
+--
+--   then the Lua table resulting from the decoding of a JSON object or
+--   JSON array is marked via Lua metatable, so that when re-encoded with
+--   JSON:encode() it ends up as the appropriate JSON type.
+--
+--   (This is not the default because other routines may not work well with
+--   tables that have a metatable set, for example, Lightroom API calls.)
+--
+--
+-- ENCODING (from a lua table to a JSON string)
+--
+--   JSON = assert(loadfile "JSON.lua")() -- one-time load of the routines
+--
+--   local raw_json_text    = JSON:encode(lua_table_or_value)
+--   local pretty_json_text = JSON:encode_pretty(lua_table_or_value) -- "pretty printed" version for human readability
+--   local custom_pretty    = JSON:encode(lua_table_or_value, etc, { pretty = true, indent = "|  ", align_keys = false })
+--
+--   On error during encoding, this code calls:
+--
+--     JSON:onEncodeError(message, etc)
+--
+--   which you can override in your local JSON object.
+--
+--   The 'etc' in the error call is the second argument to encode()
+--   and encode_pretty(), or nil if it wasn't provided.
+--
+--
+-- PRETTY-PRINTING
+--
+--   An optional third argument, a table of options, allows a bit of
+--   configuration about how the encoding takes place:
+--
+--     pretty = JSON:encode(val, etc, {
+--                                       pretty = true,      -- if false, no other options matter
+--                                       indent = "   ",     -- this provides for a three-space indent per nesting level
+--                                       align_keys = false, -- see below
+--                                     })
+--
+--   encode() and encode_pretty() are identical except that encode_pretty()
+--   provides a default options table if none given in the call:
+--
+--       { pretty = true, align_keys = false, indent = "  " }
+--
+--   For example, if
+--
+--      JSON:encode(data)
+--
+--   produces:
+--
+--      {"city":"Kyoto","climate":{"avg_temp":16,"humidity":"high","snowfall":"minimal"},"country":"Japan","wards":11}
+--
+--   then
+--
+--      JSON:encode_pretty(data)
+--
+--   produces:
+--
+--      {
+--        "city": "Kyoto",
+--        "climate": {
+--          "avg_temp": 16,
+--          "humidity": "high",
+--          "snowfall": "minimal"
+--        },
+--        "country": "Japan",
+--        "wards": 11
+--      }
+--
+--   The following three lines return identical results:
+--       JSON:encode_pretty(data)
+--       JSON:encode_pretty(data, nil, { pretty = true, align_keys = false, indent = "  " })
+--       JSON:encode       (data, nil, { pretty = true, align_keys = false, indent = "  " })
+--
+--   An example of setting your own indent string:
+--
+--     JSON:encode_pretty(data, nil, { pretty = true, indent = "|    " })
+--
+--   produces:
+--
+--      {
+--      |    "city": "Kyoto",
+--      |    "climate": {
+--      |    |    "avg_temp": 16,
+--      |    |    "humidity": "high",
+--      |    |    "snowfall": "minimal"
+--      |    },
+--      |    "country": "Japan",
+--      |    "wards": 11
+--      }
+--
+--   An example of setting align_keys to true:
+--
+--     JSON:encode_pretty(data, nil, { pretty = true, indent = "  ", align_keys = true })
+--  
+--   produces:
+--   
+--      {
+--           "city": "Kyoto",
+--        "climate": {
+--                     "avg_temp": 16,
+--                     "humidity": "high",
+--                     "snowfall": "minimal"
+--                   },
+--        "country": "Japan",
+--          "wards": 11
+--      }
+--
+--   which I must admit is kinda ugly, sorry. This was the default for
+--   encode_pretty() prior to version 20141223.14.
+--
+--
+--  AMBIGUOUS SITUATIONS DURING THE ENCODING
+--
+--   During the encode, if a Lua table being encoded contains both string
+--   and numeric keys, it fits neither JSON's idea of an object, nor its
+--   idea of an array. To get around this, when any string key exists (or
+--   when non-positive numeric keys exist), numeric keys are converted to
+--   strings.
+--
+--   For example, 
+--     JSON:encode({ "one", "two", "three", SOMESTRING = "some string" }))
+--   produces the JSON object
+--     {"1":"one","2":"two","3":"three","SOMESTRING":"some string"}
+--
+--   To prohibit this conversion and instead make it an error condition, set
+--      JSON.noKeyConversion = true
+--
+

+-- Version history:
+--
+--   20141223.14   The encode_pretty() routine produced fine results for small datasets, but isn't really
+--                 appropriate for anything large, so with help from Alex Aulbach I've made the encode routines
+--                 more flexible, and changed the default encode_pretty() to be more generally useful.
+--
+--                 Added a third 'options' argument to the encode() and encode_pretty() routines, to control
+--                 how the encoding takes place.
+--
+--                 Updated docs to add assert() call to the loadfile() line, just as good practice so that
+--                 if there is a problem loading JSON.lua, the appropriate error message will percolate up.
+--
+--   20140920.13   Put back (in a way that doesn't cause warnings about unused variables) the author string,
+--                 so that the source of the package, and its version number, are visible in compiled copies.
+--
+--   20140911.12   Minor lua cleanup.
+--                 Fixed internal reference to 'JSON.noKeyConversion' to reference 'self' instead of 'JSON'.
+--                 (Thanks to SmugMug's David Parry for these.)
+--
+--   20140418.11   JSON nulls embedded within an array were being ignored, such that
+--                     ["1",null,null,null,null,null,"seven"],
+--                 would return
+--                     {1,"seven"}
+--                 It's now fixed to properly return
+--                     {1, nil, nil, nil, nil, nil, "seven"}
+--                 Thanks to "haddock" for catching the error.
+--
+--   20140116.10   The user's JSON.assert() wasn't always being used. Thanks to "blue" for the heads up.
+--
+--   20131118.9    Update for Lua 5.3... it seems that tostring(2/1) produces "2.0" instead of "2",
+--                 and this caused some problems.
+--
+--   20131031.8    Unified the code for encode() and encode_pretty(); they had been stupidly separate,
+--                 and had of course diverged (encode_pretty didn't get the fixes that encode got, so
+--                 sometimes produced incorrect results; thanks to Mattie for the heads up).
+--
+--                 Handle encoding tables with non-positive numeric keys (unlikely, but possible).
+--
+--                 If a table has both numeric and string keys, or its numeric keys are inappropriate
+--                 (such as being non-positive or infinite), the numeric keys are turned into
+--                 string keys appropriate for a JSON object. So, as before,
+--                         JSON:encode({ "one", "two", "three" })
+--                 produces the array
+--                         ["one","two","three"]
+--                 but now something with mixed key types like
+--                         JSON:encode({ "one", "two", "three", SOMESTRING = "some string" }))
+--                 instead of throwing an error produces an object:
+--                         {"1":"one","2":"two","3":"three","SOMESTRING":"some string"}
+--
+--                 To maintain the prior throw-an-error semantics, set
+--                      JSON.noKeyConversion = true
+--                 
+--   20131004.7    Release under a Creative Commons CC-BY license, which I should have done from day one, sorry.
+--
+--   20130120.6    Comment update: added a link to the specific page on my blog where this code can
+--                 be found, so that folks who come across the code outside of my blog can find updates
+--                 more easily.
+--
+--   20111207.5    Added support for the 'etc' arguments, for better error reporting.
+--
+--   20110731.4    More feedback from David Kolf on how to make the tests for Nan/Infinity system independent.
+--
+--   20110730.3    Incorporated feedback from David Kolf at http://lua-users.org/wiki/JsonModules:
+--
+--                   * When encoding lua for JSON, Sparse numeric arrays are now handled by
+--                     spitting out full arrays, such that
+--                        JSON:encode({"one", "two", [10] = "ten"})
+--                     returns
+--                        ["one","two",null,null,null,null,null,null,null,"ten"]
+--
+--                     In 20100810.2 and earlier, only up to the first non-null value would have been retained.
+--
+--                   * When encoding lua for JSON, numeric value NaN gets spit out as null, and infinity as "1+e9999".
+--                     Version 20100810.2 and earlier created invalid JSON in both cases.
+--
+--                   * Unicode surrogate pairs are now detected when decoding JSON.
+--
+--   20100810.2    added some checking to ensure that an invalid Unicode character couldn't leak in to the UTF-8 encoding
+--
+--   20100731.1    initial public release
