Hello, so, I'm new here, Rust seems cool and all, but I'm having a bit of a hard time to get user input from the console. What's the most easy, straightforward way to get user input from the console without the newline, and also without io:: and :: scattered around all the place, and with the less …

Or using only std: fn main() { use std::io::{stdin,stdout,Write}; let mut s=String::new(); print!("Please enter some text: "); let _=stdout().flush(); stdin().read_line(&mut s).expect("Did not enter a correct string"); if let Some('\n')=s.chars().next_back() { s.pop(…

[image] jethrogb: Or in pure Rust: First of all, text_io is pure Rust. Putting code in a crate doesn't make it somehow less Rust. Secondly, your code doesn't work correctly on Windows (which uses \r\n for newlines). Also, failure on read_line is unlikely to be the user's fault. It's not l…

I'm trying to port some of my C++ code to Rust, and in C++ I just had to do: string input; getline(cin, input); cout << input;

[image] galoctopus: I'm trying to port some of my C++ code to Rust, and in C++ I just had to do: Rust tries to be more correct, but also Rust standard library is rather young still, and some ergonomic concerns will need to be addressed.

I just had a similar issue, so here's a simple mod file that will get take a simple string prompt and get a single line of input from the user. Please keep in mind that anything from a user could be hijacked by other processes so you need to run validations on what you got if this input will ever e…

simple answer is: use std::io; use std::io::*; fn main(){ let mut input = String::new(); io::stdin::().read_line(&mut input).expect("error: unable to read user input"); println!("{}",input); }

I would look at crates.io for a package: https://crates.io/crates/text_io is one example that comes to mind.
