A repost of this challenge. Meta discussion. Sandbox post. Body of the question similar to the original
This cops and robbers is now (08/03/2018) closed to further competing cop entries, as robbers may no longer be competing to crack answers, but feel free to post new answers.
The Cops challenge was won by Dennis with his brilliant 6 byte Sesos answer
The Robbers challenge was won by totallyhuman, with an astounding 30 cracks!
The Cops' Challenge
To compete as a cop:
Choose a programming language. A valid programming language is one which meets all three of these criteria:
- It has an English Wikipedia article, an esolangs article or a Rosetta Code article at the time this challenge was posted, or is on Try It Online!. Having an interpreter linked in any of these pages makes that interpreter completely legal.
- It must satisfy our rules on what constitutes a programming language
- It must have a free interpreter (as in beer). Free here means that anyone can use the program without having to pay to do so.
Write a full program that outputs the numbers from 1 to 100, inclusive, in ascending order. You can output as decimal integers, as bytecode values (
!
to represent 33, for instance), or as unary digits (1111
for 4, e.g)1. If using unary, you should use any consistent character for digits, and a different, consistent character as a delimiter. If using integers, you should output with a constant non-digit delimiter between each number. You may also output with leading and trailing characters (such as[]
) but please be sensible (don't output a thousand bytes of rubbish either side of the count for instance). You must specify your output format in your answer.You must not assume a REPL environment or existing boilerplate code. Flags may be used, but you must reveal what flags are used in your answer. The program must be in the form of one or more source files (to rule out quirky languages like Folders) and must fit into your answer in full (so it must not be longer than 65,536 characters) - this shouldn't be an issue for any serious submission.
If your code contains bytes outside of printable ASCII + newline, please include a hex dump to make sure your code is actually testable.
The program must terminate within 5 minutes on a typical desktop PC.
That's it. However, as with everything, there is a catch. You should aim to obfuscate your program as much as possible, as the Robbers' task is to guess the language you used. You should also aim to make sure that your program only works in the intended language (although this is likely to be less of a problem than the Foo cracks in the original challenge). The output format must be the same as your intended solution in order to constitute a valid crack.
Once 7 days have passed without anyone discovering any language where your program is a valid crack, you may reveal the language and mark it as safe
. Please note, your submission can still be cracked until you reveal the language.
You must not under any circumstances edit the source code of your submission once posted (as this may invalidate a robber's active attempts at cracking your answer). So make sure that you golf it as well as you can (or dare) before posting. If you realise that your answer does not work after posting it, simply delete your answer and post a fixed version if you want to.
The shortest safe submission in bytes wins!
1: If you wish to output in a different way, please ask in the comments

(Feel free to skip this section if you're not planning to participate as a cop)
This is required for new cop answers to make it possible for the snippet above to parse them.
New answers should include a header like this:
# ???, [N] bytes
where
[N]
is the size of your code in bytes and???
should appear literally.If the answer is not cracked for 7 days and you want to make your answer safe by revealing the language, simply replace the
???
and addsafe
to the end, e.g.# Ruby, [N] bytes, safe
Feel free to have the language name link to a relevant website like an esolangs page or a GitHub repository. The link will then be displayed in the leaderboard.
If another user successfully cracked your submission, please also add the language, along with a notice like
# Ruby, [N] bytes, [cracked](crack-link) by [user]
where
[user]
is the name of the user who submitted the first valid crack, andcrack-link
is a link to the corresponding answer in the Robbers' thread. Please use the short link format you get from the "share" button. Feel free to make the user name a link to their profile page.If the language used in the crack is different from the one you intended, your answer is still cracked, and you shall follow this format. However, you can mention in the answer that you intended it to be something else. It's your choice on whether you want to reveal the intended answer, or if you want to let Robbers have more fun.
Good luck Cops!
7How not to compete in this challenge. – Magic Octopus Urn – 2018-02-08T17:55:49.670
1Note that if you're using a language with an interpreter on TIO, all someone has to do to crack your submission is try every language on TIO. – mbomb007 – 2018-02-08T23:08:07.117
@mbomb007 Take a look at this comment. Aside from requesting that Robbers don't brute-force, there is nothing more that we can do to prevent this behaviour unfortunately. However, I invite anyone to downvote Robbers using scripts to brute-force submissions as it contradicts the spirit of the challenge.
– caird coinheringaahing – 2018-02-08T23:16:05.907If a submission is written in a language (say C), but it only works in a specific compiler (say ELVM 8cc), does the compiler have to have a wikipedia/rosettacode/esolangs page, or is it only required for the language itself? – NieDzejkob – 2018-02-13T13:49:54.490
@NieDzejkob I'd say that the compiler has to be on Wikipedia/Rosetta Code/Esolangs or be on TIO. – caird coinheringaahing – 2018-02-13T15:45:53.630
@cairdcoinheringaahing Both answers that inspired me to ask that question are a gray area: This Beatnik answer only works in some interpreters, and none of them have their own page. However, a working interpreter is linked on the esolangs page. In the case of this, the language is installed on TIO, but it's not listed on the language list. These answers have already been cracked, but I think that the rules should be modified to be unambigous in the future.
– NieDzejkob – 2018-02-13T16:24:21.840Also, what about languages that have a free interpreter, but the interpreter requires other, commercial software? Is the ruling different for Windows-only software that does not work in wine or mono? – NieDzejkob – 2018-02-13T16:25:51.493
@NieDzejkob In the case of the Beatnik answer, the interpreter used was linked on the esolangs page, so I'd say it's completely fine. The C answer, however, doesn't meet the first criteria, so I'd have to say it's invalid. Free means that anyone is available to use it without having to pay to do so. – caird coinheringaahing – 2018-02-13T16:51:42.570
@caird I understand that you are talking about free as in beer. However, is the operating system included, or is it an exception? This could be important for the AutoHotkey answer, for example (I haven't tried wine, mono, nor ReactOS)
– NieDzejkob – 2018-02-13T17:32:55.100@NieDzejkob I'll say that the operating system is not included in the 'free' requirement. – caird coinheringaahing – 2018-02-13T17:59:07.483
Somebody compete in Piet please. – Magic Octopus Urn – 2018-02-20T19:07:21.060
Is my safe answer invalid – Christopher – 2018-02-21T12:39:59.173
Does the leading/trailing character rule apply to codepoint output? – NieDzejkob – 2018-02-24T15:29:43.627
@NieDzejkob I'll say no (codepoint outputs can have any leading or trailing characters, same as the other output forms), because it might invalid a number of answers. – caird coinheringaahing – 2018-02-24T19:18:59.050
