lettrine-xetex-bidi.def outdated

Brief outline of the issue

lettrine-xetex-bidi.def patches an old definition of the internal command @lettrine of the lettrine package leading to issues with the current implementation.

Rather than updating the patched definition in lettrine-xetex-bidi.def, I suggest to include the RTL flag mechanism for the \parshape command in the original definition of @lettrine. I have an experimental version of lettrine.sty, appended here. Please let me know
lettrine.sty.gz
if something like that would enable to get rid of lettrine-xetex-bidi.def?

disable bidi's custom pdf properties

Brief outline of the issue

Minimal example showing the issue

% !TEX TS-program = XeLaTeX
% !TEX encoding = UTF-8 Unicode

\documentclass{article}      
\usepackage{bidi}
  
\begin{document}
  Hello!
\end{document}

Problem

The pdf and xdv produced by the minimal example contains in it the line
BIDI.Fullbanner(This is the bidi package, Version 39.8 (Release Donald Ervin Knuth) Released August 2, 2023. ),
(it is inserted to the pdf via the docinfo key). It can create problems if the the establishment to whom the pdf is created
does not accept it because of that fact. It would nice to have an appropriate way to disable that.

Today, thanks to LaTeX's new hook management system one can remove with

\documentclass{article}      
\usepackage{bidi}
 \RemoveFromHook{enddocument}[bidi]
\begin{document}
  Hello!
\end{document}

But that removes bidi's enddocument hook entirely, which might be undesirable.

New incompatibility between nicematrix and bidi

Brief outline of the issue

With a recent (2024-06-01-ish) release of LaTeX, use of the bidi package seems to break nicematrix >= 6.28. According to the discussion at Issue latex3/latex2e#1368, this may be because the array package, whose definitions bidi redefines, was recently changed.

I also reported this issue by e-mail to the nicematrix maintainer.

Horizontal positioning of a TikZ Picture with a fitted frame in a right-to-left polygossia document doesn't work as expected

Brief outline of the issue

A right-to-left document containing a wide TikZ picture with a fitted node (i.e. a node using the "fit" option from the "fit" TikZ library) cannot be displaced to the left if the displacement pushes the node beyond the text margin.

Problem with `currfile` while using `xepersian`

Brief outline of the issue

I'm experiencing an issue where using the xepersian/bidi package breaks the functionality of the currfile package.

I have a main tex file and several subdirectories where I store my other files, and I have some helper macros that facilitate inclusion of these files in the subdirectories, and those rely on \currfilebase and \currfilename. But for some reason I'm always getting the main file's name even inside the other files. This only happens when the xeperian package is imported and without it everything works fine.

The issue seems to be related to the bidi package redefining some of the underlying commands (like InputIfFileExists) and breaking the hooks (see the discussion under the thread on tex.stackexchange).

Check/indicate

Minimal example showing the issue

I created a small example that shows the behavior I'm experiencing:
main file content [main.tex]:

\documentclass[10pt]{book}
\usepackage[parent]{currfile}

\usepackage{xepersian}
\settextfont{Vazirmatn}
\setdigitfont{Vazirmatn}


\begin{document}

\begin{latin}

    This is from the main file:

    currfilepath: \currfilepath

    currfilename: \currfilename

    CurrentFile: \CurrentFile

    CurrentFilePath: \CurrentFilePath

    \input{dir/inside_dir}

\end{latin}

\end{document}

Then create a dir directory in the above directory and inside it create this inside_dir.tex file:

This is from the inside\_dir file:

currfilebase: \currfilebase

currfilepath: \currfilepath

currfilename: \currfilename

CurrentFile: \CurrentFile

CurrentFilePath: \CurrentFilePath

And then compile in the main dir using xelatex to see the output below:

xelatex main

Expected behavior

If I don't have the xepersian package, the output looks like below, which is the correct behavior:

Large banner in output is inappropriate

Whenever I use the bidi.sty package/style file, I get a long banner (25 lines!) introducing it. This boilerplate is:

  • Not useful to the user compiling a document (they know that each style file has a self-describing comment, plus there is CTAN documentation for packages, search engines etc.)
  • Contradicts the custom for (La)TeX packages
  • Clutters the log and hides meaningful messages

Please remove it entirely, or at the very list - limit yourself to a single package-describing line.

bidi causes duplicated @-expressions in longtable

Brief outline of the issue

With a recent (2024-06-01-ish) release of LaTeX, use of the bidi package in conjunction with the memoir class causes the @-expressions of longtable environments to be printed extraneously. It seems that using a \multicolumn command is necessary to trigger the bug.

According to the discussion at Issue latex3/latex2e#1368, this may be because the array package, whose definitions bidi redefines, was recently changed.

I can reproduce the problem only with memoir; the standard article and book classes seem to be unaffected.

Check/indicate

Minimal example showing the issue

\documentclass{memoir}

Expected behavior

The second longtable environment should print something like the following:

axbxcxdxexf

Instead it prints the following:

axbxcxdxexf

Allow bidi to be loaded early

Brief outline of the feature request

Check/indicate

Today, with LaTeX's new hook system it is possible to define \bidi@isloaded in such a way that bidi could be load in any order with respect to other packages. one option could be

\newcommand\bidi@isloaded[1]{
      \@ifpackageloaded{#1}%
            {\input{#1-xetex-bidi.def}}%
            {\AddToHook{package/#1/after}{\input{#1-xetex-bidi.def}}}
}

and removing the the begindocument hook from lodingorder-xetex-bidi.def and also removing the loading of the .def files from ltx-xetex-bidi.def (or moving \bidi@isloaded to there).

This is just a suggestion, I'm not sure if anything else would also be needed, but I hope this demonstrate the idea, it could make things much simpler...

Add automatic direction recognition

Brief outline of the feature request

Add one or more environment that each use a their own respective method of
automatically detecting text direction.

This will greatly improve the UX and noob-friendlyness of LaTeX as a whole
alongside the code readability.

  • This was already discussed in the Telegram and @kvafa thought it's possible
    in an unknown future time.

Check/indicate

Minimal example

\usepackage{bidi}
\begin{document}

\begin{autodir}{unicode,base=ltr}
This is a bidi text that has a phrase in it like سلام دنیا.
Which would likely be rendered as دنیا سلام if not for this environment.

With this `autodir` environment, the bidi direction will
automatically add the `rl` macro to it before processing.
