Unfortunately, you can't run this in the browser here

This program uses the regex crate and reads from stdin, so it must be run locally — it cannot run in the browser.

Add regex = "1" to your Cargo.toml dependencies, then run cargo run.

Description

This is an interactive Rust program that lets you enter a regex pattern and a string to test it against. It uses the regex crate to compile the pattern and prints whether the text matches, then asks if you want to try another — looping until you say no.

					  println!("Enter a regex pattern:");

					  io::stdin().read_line(&mut pattern_input).expect("Failed
					to read line");

					  let pattern = pattern_input.trim();

					  let re = Regex::new(pattern).unwrap();

					  let mut text_input = String::new();

					  println!("Enter text to match against the pattern:");

					  io::stdin().read_line(&mut text_input).expect("Failed to
					read line");

					  let text = text_input.trim();

					  println!("{}", re.is_match(text));

					  println!("Do you want to try another pattern? (y/n)");

					  let mut continue_input = String::new();

					  io::stdin().read_line(&mut continue_input).expect("Failed
					to read line");

					  if continue_input.trim().to_lowercase() != "y" {

					   break;

					  }

					 }

					}
