New Release: Version 23.3 2022-02-04

[vafa-khalighi]

I have uploaded version 23.3 2022-02-04 of the xepersian package to CTAN.

New Features

The following two features are implemented in this version:

• The option Ligatures=PersianTeXNoNumbers for Persian font selection control sequences is provided; this is basically the same as Ligatures=PersianTeX except that Latin numbers (including TeX counts) are not converted to the corresponding Persian ones;
• Two new control sequences \SwitchToDefaultMathDigits and \SwitchToPersianMathDigits are provided for switching between Latin and Persian math digits mid math mode. Here is an example showing how these control sequences can be used:

\documentclass{article}
\usepackage{xepersian}
\settextfont{IRXLotus}
\setmathdigitfont{IRXLotus}
\begin{document}
\[\SwitchToDefaultMathDigits
1.23\mathbf{0123}\mathit{0123}
\SwitchToPersianMathDigits
1.23\mathbf{0123}\mathit{0123}
\]
\end{document}

Note that you can use TeX grouping to restrict the effect of the two control sequences to the current group they are in. For instance, the following example has the same effect as the one above.

\documentclass{article}
\usepackage{xepersian}
\settextfont{IRXLotus}
\setmathdigitfont{IRXLotus}
\begin{document}
\[
{
  \SwitchToDefaultMathDigits
  1.23\mathbf{0123}\mathit{0123}
}
1.23\mathbf{0123}\mathit{0123}
\]
\end{document}

Fixed Issues

The issue Graphite-rendered font (Awami) not loaded correctly is fixed. The xepersian package no longer adds Script=Persian; this is not necessary with the current XeTeX and if it is needed, the user can add it manually.

Control sequence name change

The xepersian package had some control sequences with maths (Australian / British spelling) as part of their names and some other control sequences with math (American Spelling) as part of their names. This was not consistent and hence, all occurrences of maths is replaced by math. This has the consequence that, for instance, the control sequence \DefaultMathsDigits no longer exists and you will need to use \DefaultMathDigits control sequence instead.
