Abstract

TEX and its successors, including the initial version of Ω, all suffer from the same technical limitations, such as inadequate support for TrueType/OpenType font formats and the lack of distinction between character and glyph data.
In this paper, the authors present Ω2 , which provides extensibility through both external modules and the texteme concept that supersedes TEX’s tokens and nodes as well as characters and glyphs. Ω2 ’s modules, while much more
powerful than macros or ΩTPs, provide relatively easy access to Ω2 ’s internals without needing to touch the source code itself. Among immediate applications are full OpenType support (GSUB, GPOS, etc.), use of independent linguistic
tools such as hyphenation algorithms, and support for Unicode’s Bidirectional Algorithm.
