This package is a low level package that provides advanced text shaping
capabilities to graphic devices. It is based on the
[FriBidi](https://github.com/fribidi/fribidi) and
[HarfBuzz](https://harfbuzz.github.io) 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](https://ragg.r-lib.org).

A big thanks to [Behdad Esfahbod](http://behdad.org) who is the main
author of both FriBidi and HarfBuzz and has been very helpful answering
questions during the course of development.

## Installation

You can install textshaping from CRAN with
`install.packages("textshaping")`. For the development version you can
install it from Github with devtools:

``` r
devtools::install_github("r-lib/textshaping")
```

Note that you will need both the development versions of FriBidi and
HarfBuzz to successfully compile it.
