This crate allows you to read the user input cross-platform. It supports all UNIX and windows terminals down to windows 7 (not all terminals are tested see Tested Terminals for more info)
This crate is a sub-crate of crossterm to read the user input and can be used individually.
Other sub-crates are: - Crossterm Style - Crossterm Terminal - Crossterm Screen - Crossterm Cursor
When you want to use other modules as well you might want to use crossterm with feature flags.
This documentation is only for crossterm_input version 0.2 if you have an older version I suggest you check the Upgrade Manual. Also, check out the examples folders with detailed examples for all functionalities of this crate.
Add the crossterm_input package to your Cargo.toml file.
[dependencies]
`crossterm_input` = "0.2"
And import the crossterm_input modules you want to use.
```rust
extern crate crossterm_input;
pub use crossterm_input::{input, AsyncReader, KeyEvent, TerminalInput}; ```
These are the features of this crate:
The examples folder has more complete and verbose examples, please have a look at that as well.
Good documentation could be found in the docs as well in the book.
available imports
rust
use crossterm_input::{
input, InputEvent, KeyEvent, MouseButton, MouseEvent, TerminalInput, AsyncReader, SyncReader, Screen
};
Simple Readings ```rust let mut input = input();
match input.read_char() { Ok(s) => println!("char typed: {}", s), Err(e) => println!("char error : {}", e), }
match input.read_line() { Ok(s) => println!("string typed: {}", s), Err(e) => println!("error: {}", e), } ```
Read input events synchronously or asynchronously. ```rust // make sure to enable raw mode, this will make sure key events won't be handled by the terminal it's self and allows crossterm to read the input and pass it back to you. let screen = Screen::new(true);
let mut input = input();
// either read the input synchronously let stdin = input.read_sync();
// or asynchronously let stdin = input.read_async();
if let Some(keyevent) = stdin.next() { match keyevent { InputEvent::Keyboard(event: KeyEvent) => match event { /* check key event / } InputEvent::Mouse(event: MouseEvent) => match event { / check mouse event */ } } } ```
Enable mouse input events. ```rust let input = input();
// enable mouse events to be captured. input.enablemousemode().unwrap();
// disable mouse events to be captured. input.disablemousemode().unwrap(); ```
This crate supports all Unix terminals and windows terminals down to Windows 7 but not all of them have been tested. If you have used this library for a terminal other than the above list without issues feel free to add it to the above list, I really would appreciate it.
This library is average stable now, I don't expect it to not to change that much. If there are any changes that will affect previous versions I will describe what to change to upgrade.
I highly appreciate it when you are contributing to this crate. Also Since my native language is not English my grammar and sentence order will not be perfect. So improving this by correcting these mistakes will help both me and the reader of the docs.
