This crate allows you to perform terminal related actions cross-platform e.g clearing, resizing etc. 
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 perform terminal related actions, and can be use individually.

Other sub-crates are:
- [Crossterm Style](https://crates.io/crates/crossterm_style) 
- [Crossterm Input](https://crates.io/crates/crossterm_input) 
- [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://timonpost.github.io/crossterm/docs/feature_flags.html).

## Getting Started

This documentation is only for `crossterm_terminal` version `0.2` check the [examples](https://github.com/TimonPost/crossterm/tree/master/examples) folders with detailed examples for all functionality of this crate.

Add the `crossterm_terminal` package to your `Cargo.toml` file.

```
[dependencies]
crossterm_terminal = "0.2"

```
And import the `crossterm_terminal` modules you want to use.

```rust  
pub use crossterm_terminal::{terminal, Terminal, ClearType};
```

### Useful Links

- [Documentation](https://docs.rs/crossterm_terminal/)
- [Crates.io](https://crates.io/crates/crossterm_terminal)
- [Examples](/examples)

## Features
These are the features of this crate:

- Cross-platform
- Multithreaded (send, sync)
- Detailed Documentation
- Few Dependencies
- Terminal
    - Clearing (all lines, current line, from cursor down and up, until new line)
    - Scrolling (up, down)
    - Terminal Size (get/set)
    - Exit Current Process

## Command API

My first recommendation is to use the [command API](https://timonpost.github.io/crossterm/docs/command.html) because this might replace some of the existing API in the future. 
Because it is more convenient, faster, and easier to use.

## Examples

The [examples](https://github.com/TimonPost/crossterm/tree/master/examples) folder has more complete and verbose examples.

```rust 
use crossterm::terminal::{terminal,ClearType};

let mut terminal = terminal();

// Clear all lines in terminal;
terminal.clear(ClearType::All);
// Clear all cells from current cursor position down.
terminal.clear(ClearType::FromCursorDown);
// Clear all cells from current cursor position down.
terminal.clear(ClearType::FromCursorUp);
// Clear current line cells.
terminal.clear(ClearType::CurrentLine);
// Clear all the cells until next line.
terminal.clear(ClearType::UntilNewLine);

// Get terminal size
let (width, height) = terminal.terminal_size();
print!("X: {}, y: {}", width, height);

// Scroll down, up 10 lines.
terminal.scroll_down(10);
terminal.scroll_up(10);

// Set terminal size (width, height)
terminal.set_size(10,10);

// exit the current process.
terminal.exit();

// write to the terminal whether you are on the main screen or alternate screen.
terminal.write("Some text\n Some text on new line");
```

## Tested terminals

- Windows Powershell
    - Windows 10 (pro)
- Windows CMD
    - Windows 10 (pro)
    - Windows 8.1 (N)
- Ubuntu Desktop Terminal
    - Ubuntu 17.10
- (Arch, Manjaro) KDE Konsole
- Linux Mint

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.
