Encoding any string (char array) to base64 in Minecraft 1.20
A datapack library for Minecraft 1.20 that converts string (char array) into a base64 encoded string (char array) that can be compacted with a seperate library. This library does not decode the base64 code as that has been implemented before for player skull decoders (i.e. String-Parser).
Once installed, you can set the string to be encoded into the b64:convert storage under the NBT string array tag input.
Example:
data modify storage b64:convert input set value ["h","e","l","l","o"," ","w","o","r","l","d"]
To start encoding, the function is executed.
function b64:encode
The output will be found in b64:convert under the NBT string array tag result. You can concatenate the array using a library like ostrmc.
data modify storage b64:convert input set value ["N","o","t","h","i","n","g"," ","t","o"," ","s","e","e"," ","h","e","r","e"," ","4","2"]
function b64:encode
data get storage b64:convert result
Output
Storage b64:convert has the following contents: ["T", "m", "9", "0", "a", "G", "l", "u", "Z", "y", "B", "0", "b", "y", "B", "z", "Z", "W", "U", "g", "a", "G", "V", "y", "Z", "S", "A", "0", "M", "g", "=", "="]
Below are the characters that this datapack can read from the input string becore encoding.
!#$%&'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\"\\]^_`abcdefghijklmnopqrstuvwxyz{|}~�
Building this datapack uses beet, bolt, mecha and bolt-expressions. You can install them with the commands below.
