# Cross-platform Terminal Manipulation Library
Crossterm is a pure-rust, terminal manipulation library that makes it possible to write cross-platform text-based interfaces (see [features](#features)). It supports all UNIX and Windows terminals down to Windows 7 (not all terminals are tested,
see [Tested Terminals](#tested-terminals) for more info).

## Features
- Cross-platform
- Multi-threaded (send, sync)
- Detailed documentation
- Few dependencies
- Full control over writing and flushing output buffer
- Is tty
- Cursor
- Move the cursor N times (up, down, left, right)
- Move to previous / next line
- Move to column
- Set/get the cursor position
- Store the cursor position and restore to it later
- Hide/show the cursor
- Enable/disable cursor blinking (not all terminals do support this feature)
- Styled output
- Foreground color (16 base colors)
- Background color (16 base colors)
- 256 (ANSI) color support (Windows 10 and UNIX only)
- RGB color support (Windows 10 and UNIX only)
- Text attributes like bold, italic, underscore, crossed, etc
- Terminal
- Clear (all lines, current line, from cursor down and up, until new line)
- Scroll up, down
- Set/get the terminal size
- Exit current process
- Alternate screen
- Raw screen
- Set terminal title
- Enable/disable line wrapping
- Event
- Input Events
- Mouse Events (press, release, position, button, drag)
- Terminal Resize Events
- Advanced modifier (SHIFT | ALT | CTRL) support for both mouse and key events and
- futures Stream (feature 'event-stream')
- Poll/read API
### Tested Terminals
- Console Host
- Windows 10 (Pro)
- Windows 8.1 (N)
- Ubuntu Desktop Terminal
- Ubuntu 17.10
- Pop!_OS ( Ubuntu ) 20.04
- (Arch, Manjaro) KDE Konsole
- (Arch, NixOS) Kitty

- (Chrome OS) Crostini
This crate supports all UNIX terminals and Windows terminals down to Windows 7; however, not all of the
terminals have been tested. If you have used this library for a terminal other than the above list without
issues, then feel free to add it to the above list - I really would appreciate it!
## Getting Started
_see the [examples directory](examples/) and [documentation](https://docs.rs/crossterm/) for more advanced examples._
<details>
<summary>

```toml
[dependencies]
crossterm = "0.26"
```
</details>
<p></p>
```rust
use std::io::{stdout, Write};
use crossterm::{
execute,
style::{Color, Print, ResetColor, SetBackgroundColor, SetForegroundColor},
ExecutableCommand, Result,
event,
};
fn main() -> std::io::Result<()> {
// using the macro
execute!(
stdout(),
SetForegroundColor(Color::Blue),
SetBackgroundColor(Color::Red),
Print("Styled text here."),
ResetColor
)?;
// or using functions
stdout()
.execute(SetForegroundColor(Color::Blue))?
.execute(SetBackgroundColor(Color::Red))?
.execute(Print("Styled text here."))?
.execute(ResetColor)?;
Ok(())
}
```

### Feature Flags
```toml
[dependencies.crossterm]
version = "0.26"
features = ["event-stream"]
```
| `event-stream` | `futures::Stream` producing `Result<Event>`. |
| `serde` | (De)serializing of events. |
| `events` | Reading input/system events (enabled by default) |
| `filedescriptor` | Use raw filedescriptor for all events rather then mio dependency |
To use crossterm as a very tin layer you can disable the `events` feature or use `filedescriptor` feature.
This can disable `mio` / `signal-hook` / `signal-hook-mio` dependencies.
### Dependency Justification
| `bitflags` | `KeyModifiers`, those are differ based on input. | always |
| `parking_lot` | locking `RwLock`s with a timeout, const mutexes. | always |
| `libc` | UNIX terminal_size/raw modes/set_title and several other low level functionality. | optional (`events` feature), UNIX only |
| `Mio` | event readiness polling, waking up poller | optional (`events` feature), UNIX only |
| `signal-hook` | signal-hook is used to handle terminal resize SIGNAL with Mio. | optional (`events` feature),UNIX only |
| `winapi` | Used for low-level windows system calls which ANSI codes can't replace | windows only |
| `futures-core` | For async stream of events | only with `event-stream` feature flag |
| `serde` | ***ser***ializing and ***de***serializing of events | only with `serde` feature flag |
