pyio.write_json

Writes a Lua data structure to a JSON file.

pyio.write_json(path, value)

Parameter	Type	Description
path	string	The file path where the JSON should be written
value	any	A Lua value (typically a table) that should be serialized to JSON

Return value

Type	Description
nil	No return value

Example:

Writing the following Lua table

local data = {
  Type = "TEST",
  ["My Numbers"] = {1, 2, 3.5}
}

pyio.write_json("sample.json", data)

will create a JSON file with the following content:

{
  "Type": "TEST",
  "My Numbers": [1, 2, 3.5]
}

Remarks:

Lua tables are automatically mapped to JSON structures.

If a table contains only consecutive integer keys starting at 1, it is written as a JSON array. Otherwise, it is written as a JSON object with string keys.

Lua values are converted as follows:

Lua Type	JSON equivalent
table (array-like)	JSON array [...]
table (key/value)	JSON object {...}
string	JSON string
number	JSON number
boolean	JSON true / false
nil	JSON null

Only string keys are written for JSON objects. Non-string keys are ignored.

Unsupported Lua types (e.g. functions, userdata) are written as null.

The output encoding is UTF-8.
