devel/stfl 0.24p1 OpenBSD

STFL is a library which implements a curses-based widget set for text terminals. The public STFL API is only 14 simple function calls big and there are already generic SWIG bindings. Thus is very easy to port STFL to additional scripting languages.

A special language (the Structured Terminal Forms Language) is used to describe STFL GUIs. The language is designed to be easy and fast to write so an application programmer does not need to spend ages fiddling around with the GUI and can concentrate on the more interesting programming tasks.

There are two different syntaxes for STFL code, one designed to make handwriting of STFL code as easy as possible and one aiming at generated STFL code.

The STFL GUI descriptions (written in STFL code) do not contain any concrete layouting information such as x/y coordinates of widgets. Instead container widgets such as vertical and horizontal boxes as well as tables are used to group widgets and the actual layouting work is done by the STFL library. Thus STFL GUIs can handle terminals of different sizes and terminal resize events transparently for the application programmer.
