This is a work-in-progress. Only basic handling on UNIX is supported at the moment: output buffering, input key decoding and window resize detection.

ANSI terminal handling for Stakker
This is a work-in-progress. Only UNIX and the first level described below is supported for now.
Eventually this will provide several levels of abstraction at which the application may interface to the terminal, from lowest to highest:
This can be used for applications which prefer to generate the ANSI output sequences themselves directly, for example a pager or a simple editor. The application has maximum control and can use specific ANSI features to optimise its output (for example scroll regions).
The input handling decodes keypress sequences and forwards them to application code. Terminal resizes are detected and notified as soon as they occur. Terminal features such as 256 colour support are detected and notified to the application.
The application code keeps one or more full-screen pages in memory which it updates locally, and the terminal code keeps its own page which represents what is currently displayed on the terminal. When the application code wishes to update the terminal, the terminal code compares the two pages and sends a minimised update.
Input handling, resizes and features are handled the same as above.
This will provide an immediate-mode UI (fields, widgets) on top of a full-screen buffer.
