Lua 5.1, 5.2, 5.3, LuaJIT 2.0, or LuaJIT 2.1 LPeg (Tested with 0.7, 0.8, 0.9, 0.10, 0.12rc2, 1.0.1) For regressionTest: lfs (Tested with 1.6.3)

lunitx >= 0.8

LPeg 0.11 may not work - it crashed during my initial tests, it is not in the test matrix.

• Lua 5.1.5
• Lua 5.2.4
• Lua 5.3.4
• LuaJIT-2.0.4
• LuaJIT-2.1.0-beta2

All-but tests: MIT-style, See LICENSE for details tests/*: Public Domain / MIT - whichever is least restrictive

encode ( value : ANY-valid )

Takes in a JSON-encodable value and returns the JSON-encoded text Valid input types:

• table
• array-like table (spec below)
• string
• number
• boolean
• 'null' - represented by json.util.null

Table keys (string,number,boolean) are encoded as strings, others are erroneus Table values are any valid input-type Array-like tables are converted into JSON arrays... Position 1 maps to JSON Array position 0

decode (data : string, strict : optional boolean)

Takes in a string of JSON data and converts it into a Lua object If 'strict' is set, then the strict JSON rule-set is used

null

Reference value to represent 'null' in a well-defined way to allow for null values to be inserted into an array/table

undefined

Reference value to represent 'undefined' in a well-defined way to allow for undefined values to be inserted into an array/table.

IsArray (t : ANY)

Checks if the passed in object is a plain-old-array based on whether or not is has the LuaJSON array metatable attached or the custom __is_luajson_array metadata key stored.

InitArray(t: table)

Sets the 'array' marker metatable to guarantee the table is represented as a LuaJSON array type.

isCall (t : ANY)

Checks if the passed in object is a LuaJSON call object.

buildCall(name : string, ... parameters)

Builds a call object with the given name and set of parameters. The name is stored in the 'name' field and the parameters in the 'parameters' field as an array.

clone (t : table)

Shallow-clones a table by iterating using pairs and assigning.

___printValue (tab : ANY, name : string)

recursively prints out all object values - if duplicates found, reference printed

___merge (t : table, ... : tables)

Shallow-merges a sequence of tables onto table t by iterating over each using pairs and assigning.
