I’ve just worked up a preliminary Ruby gem that interfaces to the Harfbuzz
library (using FFI). It’s not a full implementation, but is enough to do basic
shaping. I’m using it successfully in a Ruby-based typesetting library that I’m
developing.
Here’s an example of how the gem can be used:
https://github.com/jslabovitz/harfbuzz-gem/blob/master/examples/example.rb
More info here:

And it’s on Rubygems — so ‘gem install harfbuzz’ if you dare.
I’d love to hear from any Ruby users who find it useful, or anyone who would
like to provide some feedback about the API.
Best,
—John
