使用 beamer babel 翻译字符串，如图形、表格、目录等。更多的字符串，如定理、例子、定义等，都可以用translator某些语言的包进行翻译。但不支持阿拉伯语translator。我怎样才能添加这些字符串的阿拉伯语翻译？
% lualatex
\documentclass{beamer}
\usepackage[bidi=basic]{babel}
\babelprovide[import=ar-DZ, main]{arabic}
\babelfont{sf}{Amiri}
\begin{document}
\begin{frame}{Test}

\begin{theorem}
\end{theorem}
\begin{example}
\end{example}
\begin{corollary}
\end{corollary}
\begin{definition}
\end{definition}
\end{frame}
\end{document}
我的目标是使用translator包，我已经创建了阿拉伯语词典
translator-months-dictionary-Arabic.dict
translator-theorem-dictionary-Arabic.dict
translator-numbers-dictionary-Arabic.dict
translator-basic-dictionary-Arabic.dict
translator-bibliography-dictionary-Arabic.dict
translator-environment-dictionary-Arabic.dict
例如translator-numbers-dictionary-Arabic.dict文件内容
\ProvidesDictionary{translator-numbers-dictionary}{Arabic}
\providetranslation{one}{واحد}
\providetranslation{two}{اثنان}
\providetranslation{three}{ثلاثة}
\providetranslation{four}{أربعة}
\providetranslation{five}{خمسة}
\providetranslation{six}{ستة}
\providetranslation{seven}{سبعة}
\providetranslation{eight}{ثمانية}
\providetranslation{nine}{تسعة}
\providetranslation{ten}{عشرة}
\providetranslation{eleven}{احدى عشرة}
\providetranslation{twelve}{اثنى عشرة}
\providetranslation{One}{واحد}
\providetranslation{Two}{اثنان}
\providetranslation{Three}{ثلاثة}
\providetranslation{Four}{أربعة}
\providetranslation{Five}{خمسة}
\providetranslation{Six}{ستة}
\providetranslation{Seven}{سبعة}
\providetranslation{Eight}{ثمانية}
\providetranslation{Nine}{تسعة}
\providetranslation{Ten}{عشرة}
\providetranslation{Eleven}{احدى عشرة}
\providetranslation{Twelve}{اثنى عشرة}
\providetranslation{first}{الأول}
\providetranslation{second}{الثاني}
\providetranslation{third}{الثالث}
\providetranslation{fourth}{الرابع}
\providetranslation{fifth}{الخامس}
\providetranslation{sixth}{السادس}
\providetranslation{seventh}{السابع}
\providetranslation{eighth}{الثامن}
\providetranslation{ninth}{التاسع}
\providetranslation{tenth}{العاشر}
\providetranslation{eleventh}{الحادي عشر}
\providetranslation{twelfth}{الثاني عشر}
\providetranslation{1st}{1.}
\providetranslation{2nd}{2.}
\providetranslation{3rd}{3.}
\providetranslation{4th}{4.}
\providetranslation{5th}{5.}
\providetranslation{6th}{6.}
\providetranslation{7th}{7.}
\providetranslation{8th}{8.}
\providetranslation{9th}{9.}
\providetranslation{10th}{10.}
\providetranslation{11th}{11.}
\providetranslation{12th}{12.}
然后我插入此行来translator.sty添加阿拉伯语选项
\DeclareOption{arabic} {\trans@use@and@alias{arabic} {Arabic}}
我尝试了这个例子，但没有得到预期的结果
% lualatex
\PassOptionsToPackage{arabic}{translator}
\documentclass{beamer}
\usepackage[bidi=basic]{babel}
\babelprovide[import,main]{arabic}
\babelfont{sf}{Amiri}
\begin{document}
\begin{frame}{Test}
\begin{theorem}
\end{theorem}
\translate[to=Arabic]{one}
\end{frame}
\end{document}
更新
@Davislor 我仍然面临一些问题，对于一种语言，我需要插入阿拉伯语，\languagepath{Arabic}但对于两种语言，最后一段代码会导致第二种语言的翻译也出现在阿拉伯语中
% lualatex
\documentclass[spanish]{beamer}
\usepackage[bidi=basic,nil]{babel}
\babelprovide[import,main]{arabic}
\babelfont{sf}{Amiri}
\uselanguage{Arabic}
%\languagepath{Arabic}
% This way translation for Spanish is ok but there is no
% translation for theorem in Arabic !
% If we incomment \languagepath{Arabic} translation for
% Arabic is ok but with Spanish translation of therem appears in Arabic !
\begin{document}
\begin{frame}{Test}
\begin{theorem}
\end{theorem}
\translate[to=Arabic]{one}
\selectlanguage{spanish}
\begin{theorem}
\end{theorem}
\end{frame}
\end{document}
不含 \languagepath{Arabic}
使用 \languagepath{Arabic}
答案1
如果你已经在 TeX 引擎搜索的某个目录中创建了字典translator-theorem-dictionary-Arabic.dict等，则需要添加以下行
\uselanguage{Arabic}
到你的序言中，和translator，beamer加载后，将使用它们。如果你想遵循translator包的命名约定，但也要translator在当前为 时选择阿拉伯语\languagename，arabic还请添加命令
\languagealias{arabic}{Arabic}
我使用了您的数字词典和以下虚拟词典translate-theorem-dictionary-Arabic.dict。我甚至没有尝试翻译阿拉伯语设置，因为您说您已经这样做了，而是放入了占位符来验证是否translator使用了正确的词典。

translator如果给它提供选项，您似乎想要修改包本身以运行两个必要的命令[arabic]。目前，您将只能使用\PassOptionsToPackage{arabic}{translator}before \documentclass{beamer}，因为目前您无法[arabic]在不将其传递给 的情况下将其传递给文档类babel，这会加载过时的 8 位.ldf文件并中断。您可以通过支持 来解决这个问题\usepackage[Arabic]{translator}。
我顺便指出，的基本设计translator甚至不足以翻译诸如“第一定理”之类的短语。它假设您可以通过替换单词将英语翻译成其他语言。这对于西班牙语语法来说也是如此，西班牙语\translate{first}会给出“primero”，而没有办法生成“primera”、“primer”、“segunda”等。它甚至更不适合德语，因为在德语中，“first”在上下文中的正确翻译可能是“erste”、“erster”、“erstem”、“ersten”或“erstes”。
原始答案
您可以使用amsthm(及其 Beamer 扩展) 定义新的定理环境，类似于 Beamer 为德语提供的环境。

标准类中没有\sectionname，Beamer 也不显示 。但是，您可以提供 Babel 支持的字幕翻译，例如\arabicchaptername或\chaptername，或者重新定义标题格式。
如果您想编写一个新包，您可能想利用translator字典。
