Bindings to the 'HarfBuzz' and 'Fribidi' Libraries for Text Shaping.

textshaping

This package is a low level package that provides advanced text shaping capabilities to graphic devices. It is based on the FriBidi and HarfBuzz libraries and provides full support for correctly shaping left-to-right, right-to-left, and bidirectional text with full support for all OpenType features such as ligatures, stylistic glyph substitutions, etc.

For an example of a package that uses textshaping to support advanced text layout see ragg.

A big thanks to Behdad Esfahbod who is the main author of both FriBidi and HarfBuzz and has been very helpful answering questions during the course of development.
