使用 xepersian 包的 beamer 中 itemize 环境中的水平间距问题

使用 xepersian 包的 beamer 中 itemize 环境中的水平间距问题

我遇到了 itemize 环境的问题，以前没有遇到过这个问题。我以前在 Texlive 2015 中用 LuaLaTex 制作波斯语幻灯片。现在，我使用的是 XePersian，带有 XeLaTeX 引擎和 Texlive 2019。问题是子项目的水平间距与项目相同，因此项目和子项目无法轻易区分。由于 beamer 与波斯语的兼容性问题，我使用了波斯语论坛中发布的一些代码，我对幻灯片的外观感到满意，但 itemize 环境问题仍未解决。以下是代码：

您可以将以下结构用于子项以及子子项：

\newcommand{\sitem}[1]{\setlength\itemindent{9pt} \item[{\small \color{blue}$\blacktriangleleft$}]#1\setlength\itemindent{2pt}}
\newcommand{\ssitem}[1]{\setlength\itemindent{18pt}\item[{\small \color{blue}$\blacktriangleleft$}]#1\setlength\itemindent{2pt}}

您有以下代码：

您可以使用beamer-rl修补一些内部投影仪模板和用于从右到左呈现的命令的类，该类使用 babel 和选项bidi=basic（lualatex 引擎）。
