Question

如何设置新的 RTL 语言以babel使用新的区域设置ini文件系统？

例如，考虑尝试建立对古典叙利亚语。我开始babel-ar.ini将它修改为我认为应该出现的样子（尽管实际上我大多只是猜测）。

然而，存在两个问题：

1. 段落方向仍为 LTR。我找不到任何地方可以设置它。
2. 字体脚本和语言设置不正确。

下面的 MWE 给出了以下警告：

Package babel Warning: The current font is not a standard family:
(babel)                NotoSansSyriac:mode=node;script=syrc;language=SYR;
(babel)                Script and Language are not applied. Consider
(babel)                defining a new family with \babelfont.
(babel)                Reported on input line 3.

对于阿拉伯语，脚本和语言是根据 的内容设置的babel-ar.ini。我假设这是来自tag.opentype和script.tag.opentype，但似乎不起作用。

字体本身报告：

$ otfinfo -s /usr/share/fonts/truetype/noto/NotoSansSyriac-Regular.ttf 
DFLT        Default
syrc        Syriac
syrc.SYR    Syriac/Syriac
syrc.SYRE   Syriac/<unknown language>
syrc.SYRJ   Syriac/<unknown language>
syrc.SYRN   Syriac/<unknown language>

我究竟做错了什么？

\selectlanguage{english}

Correct output:

\pardir TRT \textdir TRT \sycfont
ܛܘܼܒܲܝܗܘܿܢ ܠܐܲܝܠܹܝܢ ܕܲܕ݂ܟܹܝܢ ܒܠܸܒ̇ܗܘܿܢ܄ ܕܗܸܢ݂ܘܿܢ ܢܸܚܙܘܿܢ ܠܐܲܠܵܗܵܐ܂

感谢 Javier 的评论，事实证明babel需要将所有部分添加到语言ini文件中，即使它们是空的。
