This is no longer maintained, future development will be integrated into luaotfload

A HarfBuzz-based font loader and shaper for LuaTeX. It requires the experimental luahbtex engine, or installing luaharfbuzz module for the regular luatex engine.

The initial version of the shaping code was inspired by luatex-harfbuzz but was completely rewritten to use new HarfBuzz APIs and features.

There are few other projects for using HarfBuzz with LuaTeX:

• luatex-harfbuzz: Can access HarfBuzz through FFI, SWIG or use the luaharfbuzz module.
• luatex-harfbuzz-shaper: Uses luaharfbuzz module
• ufylayout: A Lua module that uses luaharfbuzz and provides BiDi support as well.
