Summary description: Unicode bidi algorithm implementation for various LuaTeX
formats
Announcement text:
* don't process lists without glyphs or with unbalanced math nodes * Fixed an infinite loop in edge cases * the disable key is removed, enable accept a bool value instead * added baselevel, setdir, setmirror, settextclass keys * In pre_linebreak_filter the direction of the loacl_par node is used for the base level instead of the direction luaotfload passes (which is the text direction) * the characters properties tables (directions, mirrors, text classes), and the base level function setter are exposed from Lua

unibidi-lua – Unicode bidi algorithm implementation for various LuaTeX formats
The package adopts the unicode bidi algorithm implementation provided in ConTeXt, and adapts it to be used in OpTeX, LaTeX and Plain TeX . It works under LuaTeX only.
