Quine Example

[crashdemons]

A Quine is a program that can output it's own source without having direct access or user intervention.

(This Means no reading of the script file, prompting for source input, packaging the source, or using inbuilt source references)

A Quine is not necessarily malicious or self-duplicating, but rather an attempt at a theory.

Definition of Quine

Why torture ourselves making this this way? The reason is to [re]prove a concept of computing: that it is possible for a turing-complete language to output it's own source-code. (or optionally, output a program in another language that outputs the original source code; aka. a multiquine )

Here, are some AutoIt3 Quines:

My Quines:

One-line quines from my reply on Page 2:

ConsoleWrite(StringReplace("ConsoleWrite(StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))",'%'&'s',Chr(34)&"ConsoleWrite(StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))"&Chr(34)))

MsgBox(0,'',StringReplace("MsgBox(0,'',StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))",'%'&'s',Chr(34)&"MsgBox(0,'',StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))"&Chr(34)))

Old 2-Line Quine:

$x="$x=%srnMsgBox(0,'Quine Example',StringFormat($x,Chr(34)&$x&Chr(34)))"
MsgBox(0,'Quine Example',StringFormat($x,Chr(34)&$x&Chr(34)))

Skeleton/Customizable Quine (Page 2)

Global $gsQuine
eq("MsgBox(0,'program','first exec line')")
eq("MsgBox(0,'program','second exec line')")
Func eq($s)
Execute($s)
$gsQuine&=BinaryToString(0x22287165)&$s&BinaryToString(0x0A0D2922)
EndFunc
$x="Global $gsQuinern%sFunc eq($s)rnExecute($s)rn$gsQuine&=BinaryToString(0x22287165)&$s&BinaryToString(0x0A0D2922)rnEndFuncrn$x=%srnMsgBox(0,'Quine Example',StringFormat($x,$gsQuine,Chr(34)&$x&Chr(34)))"
MsgBox(0,'Quine Example',StringFormat($x,$gsQuine,Chr(34)&$x&Chr(34)))

Any Questions?

Quines by Michel Claveau:

$x="MsgBox(0,'Quine','$x='&chr(34)&$x&chr(34)&@CRLF&$x)"
MsgBox(0,'Quine','$x='&chr(34)&$x&chr(34)&@CRLF&$x)

$g=chr(34)
$x="MsgBox(0,'Q','$g=chr(34)'&@CRLF&'$x='&$g&$x&$g&@CRLF&$x)"
MsgBox(0,'Q','$g=chr(34)'&@CRLF&'$x='&$g&$x&$g&@CRLF&$x)

And for my next magic trick - an AutoIt3 / PHP Polyglot (non-quine and all too simple)

A Polyglot is a script that can perform the same actions in multiple languages without manipulation of the code.

;=- <?php
;/*
ConsoleWrite(";=- Hello World -=;");
;*/
; echo "Hello World";
; ?> -=;

In either language, this outputs ";=- Hello World -=;" to the console.

Sorry for bumping, but I just had to.

Just read the wikpedia page on Quine and thought to myself: Hey! Wonder if it have been done in autoit? And indeed it had!

Very nice work (and in only 2 lines)

You've actually got a stray $ in there (hint: before 'MsgBox' in the string $x). Nice, though

[Michel Claveau]

Cool!

[NELyon]

Is this correct?

[Merovingian]

Is this correct?

Ugh huh you bet its correct *Grinz*

if in doubt read Quine Definition

I thought the point was to output the whole source. There it only goes up to "MsgBox(0, 'Quine"

You might have a vaild point there lets wait for Crash

First:

Stop centering the text in the posts, are newspapers and books center justified? No.

Second:

Just include the entire source code using FileInstall()

- or -

Using a preprocessor directive:

#AutoIt3Wrapper_res_SaveSource

See other options:

your signature is soo big it makes the page have a sidewards scroollbar.

[monoceres]

That depends on how big screen you have

[crashdemons]

Wow! don't think I've ever gotten this many replies.

Um yeah I think the $ before MsgBox was a typo when I was removing lines from it - I'll go fix it now.

Also, I'd be pleased if someone can make a different example

- although StringFormat is certainly easier than anything else I could think of.

wrapping the string in a function to try one-line makes it complicated, ugh because you have to repeat it 2+ etc.... *shrugs*

Let me know...

Shorter version of the "PHP/AutoIt" Polyglot (Editbox is broken on the first post)

;=- <?php /*
ConsoleWrite(";=- Hello World -=;");*/ echo "Hello World"; ?> -=;

PS:

I don't know exactly why it was only partially outputting for some - but just in case, try the newest edit that removed the extra '$' before MsgBox

-- also I noticed the icon on the dialog box where the problem is, I suppose it's possible there might be a compatibility issue with WINE? I don't know.

Hi!

This release, without the StringFormat:

$x="MsgBox(0,'Quine','$x='&chr(34)&$x&chr(34)&@CRLF&$x)"
MsgBox(0,'Quine','$x='&chr(34)&$x&chr(34)&@CRLF&$x)

Variante:

$g=chr(34)
$x="MsgBox(0,'Q','$g=chr(34)'&@CRLF&'$x='&$g&$x&$g&@CRLF&$x)"
MsgBox(0,'Q','$g=chr(34)'&@CRLF&'$x='&$g&$x&$g&@CRLF&$x)

Cool! that works good

[WolfWorld]

Wait you want run autoit on linux with wine ?? i tried for years and fail

[weaponx]

I am failing to see how this would be useful, you have to replicate every line of commands for running and outputting to the user. If you used something like this below you only have to define the code once:

$var = 'MsgBox(0,"","TEST")'

;Escape double quotes
$var = StringReplace($var, '"', '""')

;Format run command
$runCMD = StringFormat('"%s" /AutoIt3ExecuteLine "%s"', @AutoItExe, $var)

RunWait($runCMD)

I've been running Autoit under wine for around 8 Months now

@Weaponx:

I don't believe there is supposed to be a point. I think it's more of a "See if I can" type of thing.

[Skrip]

Sorry for bump, but can this output source as the line is called?

Like, script is on line 1, it shows only line 1, then it moves to 2, ect...

do you want line 2 to output line 2 and line 3 to output line 3 ?

that sounds very difficult

here are two One-Line-Quines for Console and MsgBox

ConsoleWrite(StringReplace("ConsoleWrite(StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))",'%'&'s',Chr(34)&"ConsoleWrite(StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))"&Chr(34)))

MsgBox(0,'',StringReplace("MsgBox(0,'',StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))",'%'&'s',Chr(34)&"MsgBox(0,'',StringReplace(%s,'%'&'s',Chr(34)&%s&Chr(34)))"&Chr(34)))
