libRUIN (Renderer for User Interfaces in Ncurses) is a rendering library for various XML-based user interface markup languages (such as XHTML or Mozilla XUL). libRUIN is using the Ncurses terminal control library as a rendering target.
GNU Guile and the SDOM Scheme module are used as the "glue" that manages user input and event handling (as such, event handlers must currently be written in Guile Scheme; support for ECMAscript event handlers is being considered for inclusion).
An application programmer passes an XML document (including, potentially, a set of CSS stylesheets) and an Ncurses WINDOW structure, and libRUIN paints the WINDOW according to the markup and CSS; the programmer may subsequently pass Ncurses-style input strings to that WINDOW via libRUIN, and libRUIN will handle the resulting event flows.

What's New in This Release: [ read full changelog ]
· This version features major improvements in performance and accuracy.
· The layout model has been rewritten to be independent from document structure, which brings libRUIN's layout and rendering pipeline into tighter compliance with the W3C CSS recommendation and allows for much greater flexibility when positioning boxes and flowing text.
· A number of bugs related to the style lookups and inheritance, layout of nested inline elements, and pseudo-element state have been resolved.
