|
|
|
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](#tested-terminals) for more info)
|
|
|
|
This crate is a sub-crate of [crossterm](https://crates.io/crates/crossterm) to read the user input and can be used individually.
|
|
|
|
Other sub-crates are:
|
|
- [Crossterm Style](https://crates.io/crates/crossterm_style)
|
|
- [Crossterm Terminal](https://crates.io/crates/crossterm_terminal)
|
|
- [Crossterm Screen](https://crates.io/crates/crossterm_screen)
|
|
- [Crossterm Cursor](https://crates.io/crates/crossterm_cursor)
|
|
|
|
When you want to use other modules as well you might want to use crossterm with [feature flags](https://crossterm-rs.github.io/crossterm/docs/feature_flags.html).

## Getting Started
|
|
|
|
All examples of how `crossterm_input` works can be found in the [examples](https://github.com/crossterm-rs/crossterm/tree/master/examples) directory.
|
|
|
|
Add the `crossterm_input` package to your `Cargo.toml` file.
|
|
|
|
```
|
|
[dependencies]
|
|
crossterm_input = "0.3"
|
|
```
|
|
Import the `crossterm_input` modules you want to use.
|
|
|
|
```rust
|
|
pub use crossterm_input::{input, AsyncReader, InputEvent, KeyEvent, MouseButton, MouseEvent, SyncReader, TerminalInput};
|
|
```
|

## Examples
|
|
The [examples](https://github.com/crossterm-rs/crossterm/tree/master/examples) folder has more complete and verbose examples.
|
|
|
|
_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 = RawScreen::into_raw_mode();
|
|
|
|
let mut input = input();
|
|
|
|
// either read the input synchronously
|
|
let stdin = input.read_sync();
|
|
|
|
// or asynchronously
|
|
let stdin = input.read_async();
|
|
|
|
if let Some(key_event) = stdin.next() {
|
|
match key_event {
|
|
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.enable_mouse_mode().unwrap();
|
|
|
|
// disable mouse events to be captured.
|
|
input.disable_mouse_mode().unwrap();
|
|
```
|
