During the slow holidays I started to think if making a quine in Inform 7 would be possible. Quine is a computer program that does nothing else but prints its own complete source code – see

Quine (computing). Turns out it is possible and here it is for your amusement: a quine for Inform 7!

I find this so overwhelmingly cool that I wanted it to see some more daylight, so I checked with Juhana that there was no objection to posting it here. Though it was written, I assume, for 5G67 or 5J39, it still compiles in 6M62 and took just a couple of very minor tweaks to make it a character-perfect quine. (Note that the source should *not* end with a linefeed: it should be exactly 2470 characters long.)

"Quine" by Juhana Leinonen
Quine is a room.
When play begins: say "[quine-list]".
To insta-quit: (- quit; -).
The L is a list of text that varies. The B is a list of numbers that varies. The Q is a list of numbers that varies. The S1 is a list of numbers that varies. The S2 is a list of numbers that varies.
