compress()

std::string love::data::compress	(	const std::string &	str,
		int	level
	)

Compresses a string or data using a specific compression level.

Parameters

str	The raw (un-compressed) string to compress.
level	(-1) The level of compression to use, between 0 and 9. -1 indicates the default level.

Returns

Compressed data in the form of a string.

var message = "Hello World!"
var compressed = love.data.compress(message)
print(compressed)
var decompressed = love.data.decompress(compressed)
print(decompressed)

decode()

std::string love::data::decode	(	const std::string &	containerType,
		const std::string &	format,
		const std::string &	sourceString
	)

Decode Data or a string to a Data or string in one of the EncodeFormats.

Parameters

containerType	What type to return the decoded data as. Only supports "string" currently.
format	The format of the input data. Can be "base64" or "hex".
sourceString	The raw (encoded) data to decode.

Returns

String which contains the decoded version of source.

(

const std::string &

str

)

Decompresses a compressed string.

Parameters

str	A string containing data previously compressed with math.compress().

Returns

A string containing the raw decompressed data.

hash()

std::string love::data::hash	(	const std::string &	hashFunction,
		const std::string &	data
	)

Compute the message digest of specified string with specified algorithm.

Parameters

hashFunction	Hash algorithm to use (md5, sha1).
data	String to hash.

Returns

Raw message digest string.

var message = "Hello World!"
var hash = love.data.hash("md5", message)
print(hash)
