Tody I will be looking at chapter 2 of the hecto tutorial. Its the basics to get a DIY text editor working.

Solution :white_check_mark:

I learnt to read raw text input from stdio and how it differs to none-raw text input. For now I’m just returning what is entered.

	use std::io::stdout;

	use crossterm::event::poll;
	use crossterm::{
	    cursor::position,
	    event::{read, DisableMouseCapture, EnableMouseCapture, Event, KeyCode},
	    execute,
	    terminal::{disable_raw_mode, enable_raw_mode},
	    Result,
	};

	use crossterm::event::KeyCode::Char;
	use crossterm::style::Print;
	use std::time::Duration;

	fn print_events() -> Result<()> {
	    loop {
	        let event = read()?;
	        if let Event::Key(x) = event {
	            match x.code {
	                Char('q') => return Ok(()),
	                Char(x) => {
	                    execute!(stdout(), Print(x.to_string()));
	                },
	                _Enter => {
	                    execute!(stdout(), Print("\n\r".to_string()));
	                }
	                _ => {
	                    execute!(
	                        stdout(),
	                        Print("special character".to_string())
	                    );
	                }
	            }
	        }
	    }
	}

	fn main() -> Result<()> {
	    enable_raw_mode()?;

	    if let Err(e) = print_events() {
	        println!("Error: {:?}\r", e);
	    }

	    disable_raw_mode()
	}
