Aleph (formerly known as e-Omega), maintained by Giuseppe Bilotta, is a project whose aim is to provide an extension to Knuth's TeX comprising both Omega 1.15 and e-TeX 2.1 features. Its main goals are stability, speed and power. It supports bidirectional typesetting and the usage of large fonts.

(In the future, pdfTeX may integrate those features as well.)

A similar project is XeTeX, but it runs under Mac OS X only.

Setup

Idris wrote in a mail from 2006-01-02:

If you already have the regular omega support files in MiKTeX etc, then great. Otherwise, here is a set of instructions for ConTeXt users:

  1. Get the Omega support files omega.zip and omegafonts.zip
  2. Get rid of the following directories from omega.zip (not really necessary but if you want to be efficient):
    texmf/eomega
    texmf/omega/encodings
  3. Put files in texmf-local
  4. Compile the Aleph format:
    mktexlsr
    texexec --make en -tex=aleph
  5. Always start Aleph files with this preamble:
     % tex=aleph output=dvipdfmx

Now test: texexec the following file (in utf-8). Download

Study \def\ArabicUTF: it uses raw Omega/Aleph commands, but see also m-gamma (in the ConTeXt distro) for some higher-level commands

Usage


TODO: can someone with more experience describe how to use large fonts and other features? (See: To-Do List)
