ABOUT
MaryPoppit.js is able to pack and unpack hidden data in regular text. For example:
This is an example!
Includes "Hello world" in every letter.
LIVE DEMO
USAGE
String prototypes
"Hello".pack("world!") will return "Hello", with one invisible watermark injected in the middle "Hello".unpack() will return "world!"
Mary object
Mary.pack("Hello", "world!", {}) will return "Hello", with one invisible watermark injected in the middle
In the third argument is an object with some optional settings:
{ afterValue OR timesValue : 2, //the watermark injection frequency, either after x amount of characters, or x-times that the watermark should be inserted chars : ["\u200c", "\u200d", "\u200e"] //the actual unicode characters that will be used. The last character indicates the beginning and the ending }
--
We can also change the invisible characters with regular ones to get a visual representation.
Mary.pack("Hello", "world!", {timesValue : 3, chars : ["A", "B", "C"]});
Will result in:
"HeCABBBABBBABBABBBBABBBAABAABBABBAAABBAABAAAABAAAABClCABBBABBBABBABBBBABBBAABAABBABBAAABBAABAAAABAAAABCloCABBBABBBABBABBBBABBBAABAABBABBAAABBAABAAAABAAAABC!"
--
Mary.pack("Hello", "world!", {timesValue : 3, chars : ["A", "B", "C"]});
Will result in:
"HeCABBBABBBABBABBBBABBBAABAABBABBAAABBAABAAAABAAAABClCABBBABBBABBABBBBABBBAABAABBABBAAABBAABAAAABAAAABCloCABBBABBBABBABBBBABBBAABAABBABBAAABBAABAAAABAAAABC!"

Another example, with one visible character at the beginning and ending of each injection (one after each 4 characters)

Now entirely invisible:
Mary.pack("Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum!", "Cool, huh?", {afterValue : 4, chars : Mary.defaultChars});
Results in:
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum!
So:
Mary.unpack("Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum!")
Results in:
["Cool, huh?"]
