How can I get user input without waiting for enter in Perl?

Tag : perl , By : Bas
Date : March 29 2020, 07:55 AM
wish help you to fix your issue From perlfaq8's answer to How do I read just one key without waiting for a return key? :
open(TTY, "+</dev/tty") or die "no tty: $!";
system "stty  cbreak </dev/tty >/dev/tty 2>&1";
$key = getc(TTY);       # perhaps this works
sysread(TTY, $key, 1);  # probably this does
system "stty -cbreak </dev/tty >/dev/tty 2>&1";
use Term::ReadKey;
$key = ReadKey(0);
use HotKey;
$key = readkey();
# HotKey.pm
package HotKey;

@ISA = qw(Exporter);
@EXPORT = qw(cbreak cooked readkey);

use strict;
use POSIX qw(:termios_h);
my ($term, $oterm, $echo, $noecho, $fd_stdin);

$fd_stdin = fileno(STDIN);
$term     = POSIX::Termios->new();
$oterm     = $term->getlflag();

$echo     = ECHO | ECHOK | ICANON;
$noecho   = $oterm & ~$echo;

sub cbreak {
    $term->setlflag($noecho);  # ok, so i don't want echo either
    $term->setcc(VTIME, 1);
    $term->setattr($fd_stdin, TCSANOW);

sub cooked {
    $term->setcc(VTIME, 0);
    $term->setattr($fd_stdin, TCSANOW);

sub readkey {
    my $key = '';
    sysread(STDIN, $key, 1);
    return $key;

END { cooked() }


PHP CLI: How to read a single character of input from the TTY (without waiting for the enter key)?

Tag : php , By : John R

will help you The solution for me was to set -icanon mode on the TTY (using stty). Eg.:
stty -icanon
system("stty -icanon");
echo "input# ";
while ($c = fread(STDIN, 1)) {
    echo "Read from STDIN: " . $c . "\ninput# ";
input# fRead from STDIN: f
input# oRead from STDIN: o
input# oRead from STDIN: o
Read from STDIN: 


// Save existing tty configuration
$term = `stty -g`;

// Make lots of drastic changes to the tty
system("stty raw opost -ocrnl onlcr -onocr -onlret icrnl -inlcr -echo isig intr undef");

// Reset the tty back to the original configuration
system("stty '" . $term . "'");


// Make lots of drastic changes to the tty
system("stty raw opost -ocrnl onlcr -onocr -onlret icrnl -inlcr -echo isig intr undef");

// Reset the tty back to sane defaults
system("stty sane");


Accept input on 1 key press instead of waiting for user to press enter on Console.ReadLine()

it helps some times I am working on a c# Console Application where the user has to only enter a number to make a selection. Instead of making the user have to type in the number and then hit enter is there a way for the input to be accept on just the number not being inputted, i.e. so the user doesn't have to press enter.e , Console.ReadKey() should work in this case

In C# I am taking a char input and then I output something. But after input control is not waiting for enter and straigh

I think the issue was by ths following , I have the following code: , For example try-parse:
Console.Write("Enter a character >\t");
char ch;
char.TryParse(Console.ReadLine(), out ch);

hasNextInt() keeps waiting for input when pressing Enter
