A place where some of my less useful Lua modules live.

UUEncoding.lua

A module that provides functions to encode and decode strings to and from the uuencoding format.
Uuencoding is a form of binary-to-text encoding, which is primarily used to convert binary data into a format that can be easily transmitted as plain text, such as email or Usenet messages.
For more info on uuencoding: Wikipedia

Features

• Encode/Decode strings and files to and from UUEncoded format.
• Efficient. Simple.
• Easy-to-Use.
• Fix all of your code issues.

Usage

local uu = require("uuencoding")

-- Encode a string
local encoded_string = uu.enc("Hello, World!")

-- Decode a string
local decoded_string = uu.dec(encoded_string)

-- Encode a file
local encoded_file = uu.encFile("_test_file.txt", "644")

-- Decode files from a encoded file string.
local file_count, decoded_files = uu.decFile("begin 644 _test_file.txt\n! Encoded Data !\n`\nend")

Base64.lua

A module that provides functions to encode and decode strings to and from the base64 encoding format.
Base64 is a method of encoding any binary data in a way that can be transmitted or stored as text. It uses a set of 64 characters (hence the name "Base64") that includes letters, numbers, and symbols to represent the binary data as a series of 6-bit values. Each group of three bytes is converted into four Base64 characters, resulting in an output string that is approximately 33% larger than the original binary data. Base64 is commonly used in email, web pages, and other applications where binary data needs to be transmitted as ASCII text.

Features

• Encode/Decode strings to and from the Base64 format.
• Optimized. Dumb, but simple.
• Easy-to-Use.
• Locate the cause of your kernel panics.

Usage

local b64 = require('base64')

-- Encode a string
local encoded_string = b64.enc("Hello, World!") -- 'b64.enc' is an alias for 'b64.encode'

-- Decode a string
local decoded_string = b64.dec(encoded_string) -- 'b64.dec' is an alias for 'b64.decode'

-- Decode a string with strict mode which disallows non-base64 characters from the input string.
-- (If input string has non-base64 characters then calls an error.)
local decoded_strict = b64.dec(encoded_string, true)
