Choose a language that's currently available on the TryItOnline site, for example PowerShell. Write code in that language on that page, that doesn't take any input, such that when the Run button is clicked, the output on that page is the exact same as what is in the "Plain URL" field when the Save/Store button is clicked instead.
For a fictitious example, suppose that
aaa was the code for a solution to this in PowerShell. Then, the result of clicking Run with
aaa as the code on
https://tio.run/#powershell should output
https://tio.run/##K8gvTy0qzkjNyfn/PzEx8f9/AA, which is also the "Plain URL" field when the Save/Store button is clicked.
The resulting URL is your submission to this challenge. The winner is the shortest URL measured in bytes. For the example above, the URL
https://tio.run/##K8gvTy0qzkjNyfn/PzEx8f9/AA is the submission to the challenge, at 44 bytes. The shortest URL that fulfills the rest of this challenge wins the challenge and earns brownie points (points not redeemable). Given that there is a distinct minimum possible length, if two submissions tie in length, the earlier submission wins.
This is the start of the URL generation algorithm in the repository. You can see how the main code area is taken, any extra elements are appended, the string is deflated and Base64 converted, and then
## prepended, etc. I won't go into full detail here; part of the challenge is to parse and understand how the URLs are generated in order to exploit any potential quirks in said algorithm.
Rules / Clarifications
- The actual code should take no input and produce only the quine-URL as output.
-- This means the only text fields that should be populated when clicking into the URL are the
Footeror corresponding "Compiler Flag" fields; the
Argumentsfields are forbidden and must remain empty/unused. Clicking the Run button should only change the
Outputfield. For this challenge, the
Debugfield is ignored in all situations.
- Usual quine rules apply to the code to the extent possible (for example, the code cannot read its own source code via
- Please include a description of how the code works in your submission.
- Submitting a "cheaty" quine by submitting a Git pull request to the TIO repository to create a "trick" URL or shortcut or the like is not allowed.
- Similarly, submitting a pull request to update a particular language to produce a "trick" URL is not allowed.
- Please be nice to Dennis' servers and don't abuse them or attempt exploits for the sake of this challenge.
