ConTeXt：如何排版阿拉伯文本？

我是 ConTeXt 世界的新手，但我需要实现的只是能够在 ConTeXt 中排版阿拉伯语/希伯来语文本以及英语文本（Bidi）。我遇到了这上下文花园的一部分与我所追求的内容相关，但在编译时无济于事，没有生成 PDF 并且没有抛出任何错误。

以下步骤按照上面的链接所述进行：

  1. 创建ara-sty.tex文件（代码在上面的同一链接中提供），大概在.tex文件的同一目录中
  2. 创建MWE.tex以下文件：

MWE:(使用 luatex 编译)

\environment ara-sty
    \starttext
    \setarabic

    هذا نص بالعربية يحتوي على ارقام ١، ٢، ٣ بالعربية أيضاً.

    \stoptext


%%% Local Variables:
%%% mode: context
%%% TeX-master: t
%%% TeX-engine: luatex
%%% End:

输出文件

Running `ConTeXt' on `MWE' with ``texexec --once --texutil  --engine=luatex --interface=en --passon="--synctex=1" --nonstop MWE.tex''

没有生成 PDF 文件，我这里遗漏了什么？

笔记

  1. 我们成功地使用 ConTeXt 编译了仅限英文的文件，但问题仅在处理阿拉伯语/希伯来语文本时出现。
  2. context --version在终端中，mu Ubuntu 机器上的 ConTeXt 版本：current version: 2015.05.18 12:26
  3. luatex --version终端中的Luatex 版本问题：This is LuaTeX, Version beta-0.80.0 (TeX Live 2015/Debian) (rev 5238)

更新-1

现在我成功地更新了我的计算机上的 ConteXt，如下所述这使用独立安装的 Ubuntu 版 ConTeXtgarden wiki 链接，然后在 中初始化树./baschrc，现在我安装了以下版本：

  1. 语境

    mtx-context     | ConTeXt Process Management 1.01
mtx-context     |
mtx-context     | main context file: /usr/local/context/tex/texmf-context/tex/context/base/mkiv/context.mkiv
mtx-context     | current version: 2017.06.27 18:05

  2. 路特克斯This is LuaTeX, Version 1.05.0 (TeX Live 2017)

  3. 即使使用最新的稳定版本 ConTeXt，我仍然遇到同样的问题：current version: 2017.05.15 21:48

所以同样的问题，没有生成 PDF 文件，如有任何帮助我将不胜感激。

更新-2 在谷歌搜索之后，我发现一个问题是我的 Emacs 设置（2017-05-06 的 GNU Emacs 25.2.2（x86_64-pc-linux-gnu，GTK+ 版本 3.18.9））使用 AucTeX 需要进行一些调整，即将变量设置ConTeXt-Mark-version为"IV"而不是其默认值"II"。

在我的点文件（设置 Emacs 文件）中进行全局设置后，如下所示：

(setq ConTeXt-Mark-version "IV")

现在，当我编译 MWE 时，我收到了以下抱怨：(1) 页之后出现问题。

我从上面的错误消息中注意到我的 luatex 是 2015，而不是如本文前面所示更新到 2017，所以我该如何解决这个问题？

答案1

[免责声明：我既不会说阿拉伯语，也不懂阿拉伯文字。]

我从中复制了相关内容来设置阿拉伯字体ara-sty.tex。这是字体功能和设置从右到左模式。然后我为阿拉伯语 Amiri 字体编写了一个打字稿，并将拉丁字符回退到 Latin Modern。它与 TL2017 上的 ConTeXt MKIV 配合使用，但我不知道这是否是您想要的。
