Hello world/Newline omission

From Rosetta Code
Task
Hello world/Newline omission
You are encouraged to solve this task according to the task description, using any language you may know.

Some languages automatically insert a newline after outputting a string, unless measures are taken to prevent its output. The purpose of this task is to output the string "Goodbye, World!" without a trailing newline.

The quoted form guarantees there are no hidden trailing spaces after World!

<nul set/p"=Goodbye, World!"
<nul set/p=Goodbye, World!

If delayed expansion is enabled, then the ! must be escaped
Escape once if quoted form, twice if unquoted.

<nul set/p=Goodbye, World^^^!

BBC BASIC[edit]

      REM BBC BASIC accepts the standard trailing semicolon:

VDU ASCMID$(GW$, i%)
NEXT

Brainf***[edit]

One option was to copy the code from the regular Hello World version and omit the last period, but one of the nicer things about the language is that no matter how simple your program is, if it's more than a few characters long, it's probably unique. So here's yet another version of Goodbye, World in Brainf***.

+++++[>++++>+>+>++++>>+++<<<+<+<++[>++>+++>+++>++++>+>+[<]>>-]<-]

C[edit]

In C, we do not get a newline unless we embed one:

#include <stdio.h>
#include <stdlib.h>
 
int main(int argc, char *argv[]) {
(void) printf("Goodbye, World!"); /* No automatic newline */
return EXIT_SUCCESS;
}

However ISO C leaves it up to implementations to define whether or not the last line of a text stream requires a new-line. This means that the C can be targetted to environments where this task is impossible to implement, at least with a direct text stream manipulation like this.

Fortran[edit]

program bye
write (*,'(a)',advance='no') 'Goodbye, World!'
end program bye

The "advance" facility was introduced with F90, as was the ability to specify format instructions (the '(A)' part) without a separate FORMAT statement. Earlier, there was a common extension:

      WRITE (6,1) "Goodbye, World!"
1 FORMAT (A,$)
END

In this, the FORMAT instruction is to accept alphabetic text (the A) from the WRITE statement, followed by the special $ item (of no mnemonic form) which signified that there was not to be any new line action at the end of the output. This sort of thing is useful when writing a prompt to the screen so that the input of the response appears on the same screen line. The text could also have been incorporated into the FORMAT statement, which would be useful if there were many WRITE statements scattered about that were to send forth the same text.

These facilities only became of interest when, instead of card decks and lineprinters, I/O involved a keyboard and screen with both input and output appearing on the same screen. Thus, in earlier Fortran usage, the issue would not arise for output to a lineprinter, because it was already the case: a line written to the lineprinter was not followed by a end-of-line/start-new-line sort of action by the lineprinter. It stayed put on the line just written. It was the following output to the lineprinter that would state "advance one" (or two, or, no) lines at the start of its output. This was the "carriage control character", and a 1 signified "skip to top-of-form" which is to say, start a new page.

In other words, the Fortran approach for output was <carriage control><output text> rather than the <output text><carriage control> sequence, that now has to be suppressed by the "advance = 'no'" facility.

Icon and Unicon[edit]

Native output in Icon and Unicon is performed via the write and writes procedures. The write procedure terminates each line with both a return and newline (for consistency across platforms). The writes procedure omits this. Additionally, the programming library has a series of printf procedures as well.

procedure main()
writes("Goodbye, World!")

J[edit]

On a linux system, you can use 1!:3 because stdout is a file:

   'Goodbye, World!' 1!:3 <'/proc/self/fd/1'
Goodbye, World!

However, J works in environments other than Linux, so... Solution:prompt from the misc package.

Example:
   load 'general/misc/prompt'
prompt 'Goodbye, World!'
Goodbye, World!

Notes: J programs are normally run from a REPL, or session manager, which comes in several flavors. The traditional commandline-based terminal (jconsole), one of several desktop applications (jqt for the current version of J, jgtk and jwd for older but still supported versions), a web-based frontend (jhs), and various mobile apps (J for iOS, Android).

The specific session manager being used changes the context and therefore answer to this task. For example, when using J from a browser (including mobile browsers) newlines are omitted by default. Further, J provides strong tools for coalescing results and manipulating them prior to output, so newline elimination would typically happen before output rather than after.

With that said, prompt handles the most common cases (using binary output for jconsole, so no newline is appended; adjusting the REPL prompt in the desktop apps to to elide the newline which is normally included by default, etc).

For truly automated processes, you'd almost always want this kind of functionality (omitting the newline when printing) in a file- or stream-oriented application. For those cases, the simple text 1!:3 file will append the text to the referenced file verbatim, without inserting any extra newlines.

So, if a J programmer were asked to solve this task, the right approach would be to ask why that is needed, and then craft a solution appropriate to that situation.

JavaScript[edit]

Node JS:

process.stdout.write("Goodbye, World!");

jq[edit]

The "-j" command-line option suppresses the newline that would otherwise be printed, e.g. if "$" is the command-line prompt:

$ jq -n -j '"Goodbye, World!"'
Goodbye, World!$

The trailing "$" is the command-line prompt.

Similarly:

$ echo '"Goodbye, World!"' | jq -j 
Goodbye, World!$

Julia[edit]

Julia provides a println function which appends a newline, and a print function which doesn't:

print("Goodbye, World!")

Kotlin[edit]

Translation of: Java
fun main(args: Array<String>) = print("Goodbye, World!")

Lasso[edit]

Lasso provides a stdoutnl method that prints a trailing newline, and a stdout method that does not:

stdout("Goodbye, World!")

Lua[edit]

ML/I[edit]

Simple solution[edit]

In ML/I, if there isn't a newline in the input, there won't be one in the output; so a simple solution is this (although it's hard to see that there isn't a newline).

Goodbye, World!

More sophisticated solution[edit]

To make it clearer, we can define an ML/I skip to delete itself and an immediately following newline.

MCSKIP " WITH " NL
Goodbye, World!""

Nemerle[edit]

using System.Console;
 
module Hello
{
// as with C#, Write() does not append a newline
Write("Goodbye, world!");

OCaml[edit]

In OCaml, the function print_endline prints a string followed by a newline character on the standard output and flush the standard output. And the function print_string just prints a string with nothing additional.

It should be noted that upon a REXX program completion, any text left pending without a C/R (or newline) is followed by a
blank line so as to not leave the state of the terminal with malformed "text lines" (which can be followed by other text
(lines) from a calling program(s), or the operating system (shell) which is usually some sort of a "prompt" text string.

TXR[edit]

Possible using access to standard output stream via TXR Lisp:

Goodbye, world!$

UNIX Shell[edit]

The echo command is not portable, and echo -n is not guaranteed to prevent a newline from occuring. With the original Bourne Shell, echo -n "Goodbye, World!" prints -n Goodbye, World! with a newline. So use a printf instead.

Works with: Bourne Shell
printf "Goodbye, World!"          # This works. There is no newline.
printf %s "-hyphens and % signs" # Use %s with arbitrary strings.

Unfortunately, older systems where you have to rely on vanilla Bourne shell may not have a printf command, either. It's possible that there is no command available to complete the task, but only on very old systems. For the rest, one of these two should work:

echo -n 'Goodbye, World!'

or

echo 'Goodbye, World!\c'

The print command, from the Korn Shell, would work well, but most shells have no print command. (With pdksh, print is slightly faster than printf because print runs a built-in command, but printf forks an external command. With ksh93 and zsh, print and printf are both built-in commands.)

Works with: ksh93
Works with: pdksh
Works with: zsh
print -n "Goodbye, World!"
print -nr -- "-hyphens and \backslashes"

C Shell[edit]

C Shell does support echo -n and omits the newline.

echo -n "Goodbye, World!"
echo -n "-hyphens and \backslashes"

Ursa[edit]

Ursa doesn't output a newline to an I/O device by default, so simply omitting an endl object at the end of the output stream is all that's needed.
