## Intro

Rustty is a terminal UI library that provides a simple, concise abstraction over an
underlying terminal device.

Rustty is based on the concepts of cells and events. A terminal display is an array of cells,
each holding a character and a set of foreground and background styles. Events are how a
terminal communicates changes in its state; events are received from a terminal, processed, and
pushed onto an input stream to be read and responded to.

## Installation

Installation is simple, to use `rustty`, first add this to your `Cargo.toml`:

```toml
[dependencies]
rustty = "*"
```

Then, add this to your crate root:

```rust
extern crate rustty;
```

## Concepts

The purpose of this section is to introduce and explain the main concepts of
rustty and the decisions behind its design.

### Terminal

The terminal representation can be thought of as such:

```
0-------------------------------cols (x)
|
|
|
|
|
|
|
|
rows (y)
```

Along the x-axis are the columns and along the y-axis are the rows. The
upper-left corner is the origin, which begins at index (0, 0) and extends to
(cols, rows). Each point (x, y) represents a single cell, which is the next
topic.

### Cells

A cell is a single point on a character display, representing a single
character and its foreground and background styles.

### Events

Events are how changes in a terminal's state are represented. 
A terminal has an associated event stream which acts much like a UNIX pipe,
or a FIFO queue. When events occur they are pushed on to
the back of the stream; when events are read they are taken
from the front of the stream.

## Usage Guide

Examples and usage suggestions can be found in the [API
documentation][1].
