A quick standard for when you want to embed an arbitrary program in the version number of your program.
2 increment the data pointer (to point to the next cell to the right). 3 decrement the data pointer (to point to the next cell to the left). + increment (increase by one) the byte at the data pointer. - decrement (decrease by one) the byte at the data pointer. . output the byte at the data pointer. 4 accept one byte of input, storing its value in the byte at the data pointer. 6 if the byte at the data pointer is zero, then instead of moving the instruction pointer forward to the next command, jump it forward to the command after the matching 9 command. 9 if the byte at the data pointer is nonzero, then instead of moving the instruction pointer forward to the next command, jump it back to the command after the matching 6 command.
This is simply Brainfuck with operators that are legal in (Debian) version numbers kept as-is, and some numbers replacing the rest.
Note that all other operators are ignored as usual. In particular, 1 and 8 are ignored, which make it easy to build version number programs that compare properly with past versions. And in some cases, adding 1 or 8 will be needed to make a particular program be a properly formatted version number.
For example, an infinite loop version number is:
A nice short hello world is:
Licensing: Yes, there should also be a way to embed a license in a version ... Oh, I mean to say, the Wikipedia excerpt above is CC-BY-SA, and the hello world is based on https://esolangs.org/wiki/Hello_world_program_in_esoteric_languages
