Narcissist
You are encouraged to solve this task according to the task description, using any language you may know.
Quoting from the Esolangs wiki page:
A narcissist (or Narcissus program) is the decision-problem version of a quine.
A quine, when run, takes no input, but produces a copy of its own source code at its output. In contrast, a narcissist reads a string of symbols from its input, and produces no output except a "1" or "accept" if that string matches its own source code, or a "0" or "reject" if it does not.
For concreteness, in this task we shall assume that symbol = character.
The narcissist should be able to cope with any finite input, whatever its length.
Any form of output is allowed, as long as the program always halts, and "accept", "reject" and "not yet finished" are distinguishable.
Ada
Took code from Quine, has to be in one line (could be done pretty printed, too, but not as simple).
with Ada.Text_IO;procedure Self is Q:Character:='"';A:String:="with Ada.Text_IO;procedure Self is Q:Character:='';A:String:=;B:String:=A(1..49)&Q&A(50..61)&Q&A&Q&A(62..A'Last);C:String:=Ada.Text_IO.Get_Line;begin Ada.Text_IO.Put_Line(Boolean'Image(B=C));end Self;";B:String:=A(1..49)&Q&A(50..61)&Q&A&Q&A(62..A'Last);C:String:=Ada.Text_IO.Get_Line;begin Ada.Text_IO.Put_Line(Boolean'Image(B=C));end Self;
ALGOL 68
STRINGs="STRINGs="";print(readstring=2*s[:9]+2*s[9:])";print(readstring=2*s[:9]+2*s[9:])Output: T or F depending on input.
AppleScript
As long as the script hasn't been exported as run-only (ie. without its source code):
(display dialog "" default answer "")'s text returned = (do shell script ("osadecompile " & (path to me)'s POSIX path's quoted form))
- Output:
Depending on the text entered and button clicked, one of:
true
false
error "User cancelled." number -128
Arturo
blk:[print (("blk:" ++ (as .code blk) ++ "do blk") = input "") ? -> "accept" -> "reject"]do blk
- Output:
$ arturo narcissist.art < narcissist.art accept
AutoHotkey
Narcissist(Input) {
FileRead, Source, % A_ScriptFullPath
return Input == Source ? "accept" : "reject"
}
Example Use:
MsgBox, % Narcissist(FileOpen(A_ScriptFullPath, "r").Read()) "`n"
. Narcissist("This isn't the text you're looking for.")
- Output:
accept reject
BBC BASIC
Prints '1' on success and '0' on failure.

Befunge
Reads from stdin up to the first carriage return, line feed, or EOF. However, the latter is not guaranteed to work on all Befunge implementations - in particular not on Befunge-98 - so a line break is recommended.
Outputs 1 if the given line of input matches the source code, and 0 if it doesn't.

C
Based upon the quine. Reads until EOF or newline from stdin, and writes "1" or "0" to stdout.

Since we can't put a link statement and program on a single line, we implement a simplified inline sprintf so we don't have to deal with all the double quotes or substrings and offsets. If we'd needed to write multiple procedures on a line it can be done Semi-colons in the language intro
Example:
./narcissist.exe < narcissist.icn Accept
Actually, this version recognizes all files where the first line is the Narcissist.

Interpreted-only, as is: to allow a compiled version to run, change command_line()[2] to (say) "test.exw"
or maybe substitute(command_line()[2],".exe",".exw"), and ship with/install the source code file.

Raku
(formerly Perl 6)
For the narcissist to work you must be very careful with whitespace. The following version works if it is given to standard input as exactly one line terminated by a newline character.
Note how the code takes advantage of Raku's ability to nest quoting delimiters.
EVAL my $self = q{say slurp() eq q[EVAL my $self = q{]~$self~q[}]~10.chr ?? q{Beautiful!} !! q{Not my type.}}
- Output:
$ narcissist='EVAL my $self = q{say slurp() eq q[EVAL my $self = q{]~$self~q[}]~10.chr ?? q{Beautiful!} !! q{Not my type.}}'
$ raku -e "$narcissist" <<<"$narcissist"
