!!!Batch is another derivative of the Batch programming language created by Shubshub :D. !!!Batch is an encoding of Batch where each character is in the form of a question mark, followed by some amount of exclamation marks, then an optional marking character, and finally another question mark. Other characters are returned as-is. Since !!!Batch is an encoding of Batch, and Batch is Turing complete, so is !!!Batch.

Syntax

Source code for version 1.3 is formatted as set str=<code>, with <code> being the !!!Batch source code. The code is decoded into ASCII characters which are then put into a Batch file. The output file always begins with @echo off and ends with pause. Since the input file is executed as a Batch file, it has access to the entire language before being compiled, effectively making Batch its meta-language.

Further versions have code formatted plainly in a file. The file is no longer executed, and the heading @echo off and footing pause are omitted. Additionally, the official translators also execute the resulting output file.

Encoding

Each version has a different alphabet.

• Version 1.3: abcdefghijklmnopqrstuvwxyz& ?!\/.:0123456789|
• Version 1.5: abcdefghijklmnopqrstuvwxyz& ?!%/.:0123456789=+-<>@*, upper ABCDEFGHIJKLMNOPQRSTUVWXYZ
• Version 2.0: abcdefghijklmnopqrstuvwxyz, middle & ?!%/.:0123456789=+-<>@*, upper ABCDEFGHIJKLMNOPQRSTUVWXYZ

The number of exclamation marks in a character's encoding corresponds to its 1-based index in its alphabet, e.g. a has 1 mark, z 26, A 1, etc. If the character in the upper alphabet a plus is appended, or if in the middle, a hyphen minus. Characters in the normal alphabet don't have a character appended. Finally, the result is surrounded by a question mark on both sides. Select encodings in version 2.0:

• a: ?!?
• b: ?!!?
• %: ?!!!!!-?
• A: ?!+?
• D: ?!!!!+?

Examples

Hello world (version 1.3)

Hello World In !!!Batch :D

set str=?!!!!!??!!!??!!!!!!!!??!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!!!!!!!!!!??!!!!!!!!??!!!!!??!!!!!!!!!!!!??!!!!!!!!!!!!??!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!??!!!!!!!!!!!!??!!!!??!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!?

Hello world (version 1.5)

Hello world example (because some of the code has changed). This outputs Hello World! (Because !!!Batch now supports capital lettering).

?!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!??!!!!!??!!!??!!!!!!!!??!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!??!!!!!!??!!!!!!?
?!!!!!??!!!??!!!!!!!!??!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!!!!!!!!!!??!!!!!!!!+??!!!!!??!!!!!!!!!!!!??!!!!!!!!!!!!??!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!!!!!+??!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!??!!!!!!!!!!!!??!!!!??!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!?
?!!!!!!!!!!!!!!!!??!??!!!!!!!!!!!!!!!!!!!!!??!!!!!!!!!!!!!!!!!!!??!!!!!?

This converts to

@echo off
echo hello world!

Multi version translator

This Python script supports translating the major versions of !!!Batch into ASCII. It doesn't support use of Batch as a meta-language while being translated.

upperbet = ('ABCDEFGHIJKLMNOPQRSTUVWXYZ', '+')

version_bets = {
    '1.3': [(lowerbet[0] + middlebet13[0], '')],
