If the input is, say, N, your IF lines evaluate like this: If N==”y” goto yes If N==”n” goto no … That is, you are comparing N with “y”, then “n” etc. including “N”. You are never going to get a match unless the user somehow decides to input “N” or “y” (i.e. either of … Read more
You can use the read module (disclosure: written by me) for this: In your shell: npm install read Then in your JS: var read = require(‘read’) read({ prompt: ‘Password: ‘, silent: true }, function(er, password) { console.log(‘Your password is: %s’, password) })
Here is a version with all optional type annotations and error handling which may be useful for beginners like me: use std::io; fn main() { let mut input_text = String::new(); io::stdin() .read_line(&mut input_text) .expect(“failed to read from stdin”); let trimmed = input_text.trim(); match trimmed.parse::<u32>() { Ok(i) => println!(“your integer input: {}”, i), Err(..) => println!(“this … Read more
Note that since Kotlin 1.6 readLine()!! should be replaced with readln(). Here are A+B examples in Kotlin reading from stdin: fun main() { val (a, b) = readLine()!!.split(‘ ‘) println(a.toInt() + b.toInt()) } or fun main(vararg args: String) { val (a, b) = readLine()!!.split(‘ ‘).map(String::toInt) println(a + b) } or fun readInts() = readLine()!!.split(‘ ‘).map … Read more
The solution below works very well for me. Only 4 lines and works with most (all?) characters. Solution: :Trim SetLocal EnableDelayedExpansion set Params=%* for /f “tokens=1*” %%a in (“!Params!”) do EndLocal & set %1=%%b exit /b Test: @echo off call :Test1 & call :Test2 & call :Test3 & exit /b :Trim SetLocal EnableDelayedExpansion set Params=%* … Read more
You can use set with the /p argument: SET /P variable=[promptString] The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty. So, simply use something like set /p Input=Enter … Read more
You don’t need to import the ‘Input’ from ‘angular/core’. Simply: import {Component,ViewChild} from ‘@angular/core’; import {NavController, TextInput } from ‘ionic-angular’; @Component({ templateUrl: ‘build/pages/home/home.html’ }) export class HomePage { @ViewChild(‘input’) myInput: TextInput; constructor(private navCtrl: NavController) { } ionViewDidLoad() { setTimeout(() => { this.myInput.setFocus(); },150); } } And answering comment to Ciprian Mocanu: It does not work … Read more
Rust 1.x (see documentation): use std::io; use std::io::prelude::*; fn main() { let stdin = io::stdin(); for line in stdin.lock().lines() { println!(“{}”, line.unwrap()); } } Rust 0.10–0.12 (see documentation): use std::io; fn main() { for line in io::stdin().lines() { print!(“{}”, line.unwrap()); } } Rust 0.9 (see 0.9 documentation): use std::io; use std::io::buffered::BufferedReader; fn main() { let … Read more
Why not use the <textarea> tag? <textarea id=”txtArea” rows=”10″ cols=”70″></textarea>
Very old thread, but this seems neater and strips out non-numeric characters if pasted. // force the field to be numeric only textField.textProperty().addListener(new ChangeListener<String>() { @Override public void changed(ObservableValue<? extends String> observable, String oldValue, String newValue) { if (!newValue.matches(“\\d*”)) { textField.setText(newValue.replaceAll(“[^\\d]”, “”)); } } });
