Hello world/Standard error

Hello world/Standard error
You are encouraged to solve this task according to the task description, using any language you may know.

Hello world/Standard error is part of Short Circuit's Console Program Basics selection.

A common practice in computing is to send error messages to a different output stream than normal text console messages.

The normal messages print to what is called "standard output" or "standard out".

The error messages print to "standard error".

This separation can be used to redirect error messages to a different place than normal messages.

Task

Show how to print a message to standard error by printing     Goodbye, World!     on that stream.

To print a message to standard error, pipe it through a shell command:

BEGIN {
  print "Goodbye, World!"| "cat 1>&2"
}

Or write to /dev/stderr:

Works with: gawk

Works with: mawk

Works with: nawk

BEGIN {
  print "Goodbye, World!" > "/dev/stderr"
}

With gawk, mawk and nawk: a special feature associates "/dev/stderr" with standard error. The manuals of gawk and mawk describe this feature; nawk also has this feature.

Other implementations might try to open /dev/stderr as a file. Some Unix clones, like BSD, have a /dev/stderr device node that duplicates standard error, so this code would still work. Some systems have no such device node, so this code would fail. We recommend "cat 1>&2", which is more portable, and works with any Unix clone.

Normally standard error is associated with the unit 0 but this could be different for different vendors. Therefore since Fortran 2003 there's an intrinsic module which defines the parameter ERROR_UNIT.

Go

Built in println now goes to stderr.

func main() { println("Goodbye, World!") }

but the builtin print() and println() functions are not guaranteed to stay in the language. So you should probably use

func main() { fmt.Fprintln(os.Stderr, "Goodbye, World!") }

LLVM

; This is not strictly LLVM, as it uses the C library function "printf".
; LLVM does not provide a way to print values, so the alternative would be
; to just load the string into memory, and that would be boring.

; Additional comments have been inserted, as well as changes made from the output produced by clang such as putting more meaningful labels for the jumps

%struct._iobuf = type { i8* }

$"message" = comdat any
@"message" = linkonce_odr unnamed_addr constant [17 x i8] c"Goodbye, world!\0A\00", comdat, align 1

;-- For discovering stderr (io pipe 2)
declare %struct._iobuf* @__acrt_iob_func(i32)

;--- The declaration for the external C fprintf function.
declare i32 @fprintf(%struct._iobuf*, i8*, ...)

define i32 @main() {
;-- load stderr
  %1 = call %struct._iobuf* @__acrt_iob_func(i32 2)
;-- print the message to stderr with fprintf
  %2 = call i32 (%struct._iobuf*, i8*, ...) @fprintf(%struct._iobuf* %1, i8* getelementptr inbounds ([17 x i8], [17 x i8]* @"message", i32 0, i32 0))
;-- exit

Metafont

Metafont has no a real way to send a text to the standard output/error nor to a file. Anyway it exists the errmessage command which will output an error message and prompt the user for action (suspending the interpretation of the source).

errmessage "Error";
message "...going on..."; % if the user decides to go on and not to stop
                          % the program because of the error.

min

Works with: min version 0.37.0

Currently, min has three possibilities for outputting to stderr:

"Goodbye, World!" warn!
"Goodbye, World!" error!
"Goodbye, World!" fatal!

The first two depend on the current log level (and are enabled by default). The last one additionally terminates the program.

Objective-C

Works with: GNUstep

Works with: Cocoa

In Objective-C one can use the standard C library and the stderr as in the C language; nonetheless a common way to output to stderr for logging purpose and/or error notification is the NSLog function, that works almost like fprintf(stderr, "..."), save for the fact that the format string is an NSString object, and it also prepends a timestamp.

#import <Foundation/Foundation.h>

int main()
{
   fprintf(stderr, "Goodbye, World!\n");
   fputs("Goodbye, World!\n", stderr);
   NSLog(@"Goodbye, World!");
   return 0;
}

OCaml

prerr_endline "Goodbye, World!";    (* this is how you print a string with newline to stderr *)
Printf.eprintf "Goodbye, World!\n"; (* this is how you would use printf with stderr *)

we can also use the out_channel stderr:

output_string stderr "Goodbye, World!\n";
Printf.fprintf stderr "Goodbye, World!\n";

finally the Unix module also provides unbuffered write functions:

let msg = "Goodbye, World!\n" in
ignore(Unix.write Unix.stderr msg 0 (String.length msg)) ;;

Octave

fprintf(stderr, "Goodbye, World!\n");

System.Err "Goodbye, World!" << cr

Ol

ooRexx

ooRexx provides a .error object that writes output to the standard error stream.

.error~lineout("Goodbye, World!")

The .error object is a proxy that delegates to a backing stream, so this might be redirected. By default, this delegates to the .stderr object, which can also be used directly.

.stderr~lineout("Goodbye, World!")

STDERR "Goodbye, World!"

PowerShell

Since PowerShell has a slightly different system of pipes and streams (to facilitate easy usage from a host application) the standard Write-Error cmdlet is mainly for sending annotated error messages to the host:

Write-Error "Goodbye, World!"

Note that this outputs more than just the message, because behind the scenes it is an uncaught exception:

Write-Error "Goodbye, World!" : Goodbye, World!
    + CategoryInfo          : NotSpecified: (:) [Write-Error], WriteErrorException
    + FullyQualifiedErrorId : Microsoft.PowerShell.Commands.WriteErrorException

To accurately reproduce the behavior of other languages one has to resort to .NET in this case:

[Console]::Error.WriteLine("Goodbye, World!")

PureBasic

ConsoleError() writes the message string (plus a newline) to the standard error output of current program.

Standard error output can be used in conjunction with ReadProgramError() to reads a line from an other programs error output (stderr).

ConsoleError("Goodbye, World!")

REXX

version 1

This version will work with those operating systems (hosts) that support stream output and a STDERR output
stream (by name).
If the   stderr   name is supported and enabled, the output is written to the terminal.
If not supported or disabled, the output is written to a (disk) file named   STDERR.

call lineout 'STDERR', "Goodbye, World!"

version 2

Same as above, but uses a different style and also invokes   charout   instead of   lineout.

msgText = 'Goodbye, World!'
call charout 'STDERR', msgText

version 3

This works on Windows 7 and ooRexx and REGINA

Ad hoc REPL solution

Ad hoc solution as REPL script:

Console.err.println("Goodbye, World!")

Via Java runtime

This is a call to the Java run-time library. Not recommendated.

System.err.println("Goodbye, World!")

Via Scala Console API

This is a call to the Scala API. Recommendated.

Console.err.println("Goodbye, World!")

Short term deviation to err

Console.withOut(Console.err) { println("This goes to default _err_") }

Long term deviation to err

  println ("Out not deviated")
  Console.setOut(Console.err)
  println ("Out deviated")
  Console.setOut(Console.out) // Reset to normal

Scheme

(error "Goodbye, World!")

Scilab

error("Goodbye, World!")

sed

Requires /dev/stderr

#n
1 {
	s/.*/Goodbye, World!/w /dev/stderr
}

This program requires at least 1 line of input. It changes the first line to "Goodbye, World!" and then prints the first line to standard error. It reads and ignores the remaining lines.

Test output:

$ echo a | sed -f error.sed >/dev/null
Goodbye, World!

Seed7

$ include "seed7_05.s7i";

const proc: main is func
  begin
    writeln(STD_ERR, "Goodbye, World!");
  end func;

Sidef

STDERR.println("Goodbye, World!");

Slate

inform: 'Goodbye, World!' &target: DebugConsole.

Slope

(write "Goodbye, world!" stderr)

Smalltalk

The details on to which name stderr is bound may vary between Smalltalk dialects. If different, a "Smalltalk at:#Stderr put:<name your stream here>" should provide compatibility.

Stderr nextPutAll: 'Goodbye, World!'

However, all Smalltalks provide a console named "Transcript", where diagnostics is usually sent to (which is convenient, if there is no stderr to look at, as when started in Windows as an exe, vs. a com).
Thus:

Transcript show: 'Goodbye, World!'

will work on all, and is the preferred way to do this.
(and yes, when running UI-less as a console program, the global "Transcript" is usually bound to the stderr stream).

The above tells the stream to write a string; you can also tell the string to print itself onto some stream:

'Goodbye, World!' printOn: Stderr

Both have the same effect.

SNOBOL4

        terminal = "Error"
        output = "Normal text"
end

Standard ML

TextIO.output (TextIO.stdErr, "Goodbye, World!\n")

Swift

import Foundation

let out = NSOutputStream(toFileAtPath: "/dev/stderr", append: true)
let err = "Goodbye, World!".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false)
out?.open()
let success = out?.write(UnsafePointer<UInt8>(err!.bytes), maxLength: err!.length)
out?.close()

if let bytes = success {
    println("\nWrote \(bytes) bytes")
}

Output:

Goodbye, World!
Wrote 15 bytes

Tcl

puts stderr "Goodbye, World!"

Transact-SQL

 RAISERROR 'Goodbye, World!', 16, 1

True BASIC

CAUSE error 1, "Goodbye World!"
END

TUSCRIPT

$$ MODE TUSCRIPT
PRINT/ERROR "hello world"
text="goodbye world"
PRINT/ERROR text

Output:

@@@@@@@@  hello world                                                  @@@@@@@@
@@@@@@@@  goodbye world                                                @@@@@@@@

UNIX Shell

Works with: Bourne Shell

echo "Goodbye, World!" >&2

C Shell

echo "Goodbye, World!" >/dev/stderr

This requires /dev/stderr, a device node from BSD and some other Unix clones. This command works with both Bourne Shell and C Shell.

Ursa

out "goodbye, world!" endl console.err

VBA

Sub StandardError()
    Debug.Print "Goodbye World!"
End Sub

VBScript

Must work in cscript.exe

WScript.StdErr.WriteLine "Goodbye, World!"

Verbexx

@STDERR "Goodbye, World!\n";

Visual Basic .NET

Module Module1

    Sub Main()
        Console.Error.WriteLine("Goodbye, World!")
    End Sub

End Module

WDTE

io.writeln io.stderr 'Goodbye, World!';

Wren

Fiber.abort("Goodbye, World!")

X86 Assembly

Works with: nasm version 2.05.01

This is known to work on Linux, it may or may not work on other Unix-like systems

Note that it is only 2 characters different from the Assembly example on User Output - text

Prints "Goodbye, World!" to stderr (and there is probably an even simpler version):

section .data
msg     db      'Goodbye, World!', 0AH
len     equ     $-msg

section .text
global  _start
_start: mov     edx, len
        mov     ecx, msg
        mov     ebx, 2
        mov     eax, 4
        int     80h

        mov     ebx, 1
        mov     eax, 1
        int     80h

XLISP

(DISPLAY "Goodbye, World!" *ERROR-OUTPUT*)

XPL0

The terms "standard output" and "standard error" are not used, but it's trivial to send messages to a variety of devices by specifying their numbers. Normally messages are displayed on the text console, which is device 0. Instead, this example sends the message to the (first) printer, which is device 2.

code Text=12;
Text(2, "Goodbye, World!")

Yabasic

error "Goodbye World!"

Zig

const std = @import("std");
pub fn main() !void {
    try std.io.getStdErr().writer().writeAll("Goodbye, World!\n");
    // debug messages are also printed to stderr
    //std.debug.print("Goodbye, World!\n");
}

zkl

File.stderr.writeln("Goodbye, World!")
