Recently I’ve worked on a Hebrew document in LaTeX and wanted to use the split environment to typeset a multiline formula. The document, which compiled just fine until that point, failed to compile with the following error:
Package amsmath Error: begin{split} won't work here.

When writing a document that contains mathematics, many times the need to add an explanation (e.g., stating the theorem used) arises. To address this need, I wrote two short LaTeX macros: explain and explainup.

A few days ago, I finally decided to install IvriTeX-1.2.1 on my system. I’m running teTeX-3.0. The new version of IvriTeX includes some very important improvements and, at least for me, the most important thing is support for the Culmus fonts. teTeX-3.0 introduced a major directory change, which causes many problems when installing packages that are unaware of the changes. In this post, I will try to walk through the installation process.
TEXMF will be the directory of your local TeX tree (usually /usr/share/texmf). Before beginning the installation process, make sure you have the Culmus fonts installed. Apparently, Culmus is not optional; it’s a requirement. I’ll assume that your Culmus fonts are installed in /usr/share/fonts/culmus.

If you ever wrote a document in LaTeX (or TeX) that used inline formulas, you know how frustrating it is when LaTeX insists on breaking your inline formula across two lines. The easiest solution to this problem, in my opinion, is to prevent line breaks in inline formulas at all except under extreme cases. To prevent line breaks in inline formulas, just add the following two lines to your preamble:
relpenalty=9999
binoppenalty=9999
Now I will explain what we did. relpenalty=[number parameter]: the parameter specifies the penalty for breaking a math formula after a relation when the formula appears in a paragraph. Plain TeX sets relpenalty to 500. binoppenalty=[number parameter]: the parameter specifies the penalty for breaking a math formula after a binary operator when the formula appears in a paragraph. Plain TeX sets binoppenalty to 700. Both parameters can be set anywhere from 0 to 10000. If set to 10000, the inline formulas will never break, even in extreme cases. Setting it a bit lower would prevent line breaking except where TeX would encounter extreme cases that must have a line break because of the situation.
This guide is based on a guide published by Dekel Tsur that can be found here. Dekel Tsur’s guide was very good, but now it is outdated since it doesn’t work with teTeX 3.0. In this guide, I addressed this issue and updated the instructions and scripts so they will work with teTeX 3.0. Since the quality of the Hebrew metafonts that come with Hebrew LaTeX is quite poor, alternative fonts are needed. The best-quality free Hebrew fonts are TrueType fonts (for example, the Times New Roman/Arial/Courier New fonts). Using TrueType fonts with TeX is somewhat complicated, but it is quite easy with pdfTeX, as pdfTeX has native support for TrueType fonts. This document explains how to use TrueType fonts with pdfTeX. Since Hebrew requires the use of the eTeX engine, you need to have the pdfelatex program. It is available in teTeX 1.0 (which comes with recent Linux distributions). The instructions below allow using nikud, although the result is quite poor as the nikud glyphs are not aligned correctly (but it is better than nothing).
