@evacide Me too. Who has the time to write stuff, though? My best approximation of writerly pursuits is half choose-your-own-adventure stuff and half PoC||GTFO.

So I saw a quine earlier and had to make my own. tatwd. The code half stays byte-identical every run, only the stack of turtles in the source grows. No bottom. Just turtles all the way down

#python #quine #buildinpublic

s='s=%r;print(s%%s)';print(s%s)

#Python #Quine

Write a program that outputs an exact copy of its source code (without reading any files).

Additional constraints:

• Write the program in portable standard C.
• All output must come from a single fputs(src, stdout) call where src is an array of char.
• The main function must be exactly int main(void) { fputs(src, stdout); return 0; }.

On the tangential topic of quines.

Here is my "due diligence".
By the way, in October I realized on my own a quine could be done with
`lambda' and `let', tried to work it out, ran out of time, left it
aside, and, alas, never went back to it...

(defun quinep (form)
"Test whether a non-atom FORM evaluates to itself.
Test equality with `equalp' for better coverage (of implementations
that construct structures when reading backquoted expressions)."
;; A justified use of `eval'.
(and (not (atom form))
(equalp form (eval form))))

;; NB: `*print-pretty*' may affect the printing of backquotes.

Thanks to the #c23 #embed macro, I may have written the world's shortest #quine.
```c
#include<stdio.h>
int main(){puts((char[]){
#embed"q.c"
,0});}
```
(I doubt that I'm the first to do this)
We just need to politely ignore the extra `\n` injected by `puts`. Otherwise, replace `puts` with `printf`.

Very similar to my interpretation of last year's Genuary 3 "42 Lines of Code" (link below), this code is a "Quine" that outputs itself into a stylized image using SVG curves and gradients.

This is an unbirthday present for @screwlisp,
who posted earlier about quines.

To give it as a puzzle at first:

find a Python quine as a string Q such that eval(Q) == Q.

A spoiler to follow.

_________
The term "fixed point" comes to mind. And the Y combinator comes into
this picture as well; wie another day.

(Estimating Python's degree of homoiconicity is left as an exercise.)

Worth noting: there is already a Rockstar quine, and it's actually quite pretty, as are most Rockstar programs.

the world is a sea
burn the world in fire
the song says shout "the world is a sea" with fire, "burn the world in fire", fire, "the song says " with the song, and fire with the song
shout "the world is a sea" with fire, "burn the world in fire", fire, "the song says " with the song, and fire with the song

#quine #rockstarlang

I should write a quine in Rockstar that actually outputs itself in reverse, i.e. a quine that only works via back-masking.

#quine #rockstarlang

A couple of #Python #Quine one-liners.

s='s=%r;print(s%%s,)';print(s%s,)

(lambda s: s%s)('(lambda s: s%%s)(%r)')

E.g.:

>>> s = "(lambda s: s%s)('(lambda s: s%%s)(%r)')"
>>> eval(s) == s
True

I don't remember where I found this, a "naturally occurring" #quine in #Python exception handling.

$ python exceptionQuine.py
File "exceptionQuine.py", line 1
File "exceptionQuine.py", line 1

Next episode of Super Tipiak75: all stars in AoC world. ⭐

Day17 was interesting : part1 involved running machine language on an imaginary CPU and lookup output, pretty straightforward. Part2 was about modifying the output in order for the program to output a quine. Pure logic and little coding got me that last star in the end.

C. F. Santos が批判する、直観に基づく論理学における「直観」は心理主義的な意味におけるそれだが、哲学における直観は超越論的でありベイズ主義的なものではない。つまり、超越論的な直観と論理体系は整合しうるが、心理主義的な直観と論理体系は独立したものでありうる。これは超越論的言語観と同型をなす。超越論的言語観において、私の言語は世界に等価である。同じように超越論的論理観では、私の直観的論理体系は先験的でしかありえない。論理における反例外主義（AEL）において修正される直観とは、心理主義的な意味におけるそれであり、超越論的なそれではない。
