This library provides an abstracted mechanism for building interactive full-screen terminal programs. It provides a full set of output drawing functions, and handles keyboard and mouse input events.

Using this library, applications can

Divide the terminal into a hierarchy of nested, possibly-overlapping rectangular windows
Render output content and react to input events independently in any window region
Use fully Unicode-aware string content, including non-BMP, fullwidth and combining characters
Draw line-art using Unicode box-drawing characters in a variety of styles
Operate synchronously or asynchronously via file descriptors, or abstractly via byte buffers
Recognise arbitrary keyboard input, including modifiers*
Make use of multiple terminals, if availble, from a single application

The following terminal features are supported:

Many rendering attributes; bold, italics*, underline, reverse, strikethough*, alternate font*
256 and 24-bit (16million) colours*
Mouse including mouse wheel and recognition of position reporting greater than 224 columns*
Arbitrary scrolling regions*

*: Not all terminals may support these features
