Expex 和 RL 语言（阿拉伯语）以及 LR 自由文本（英语）

Question

我正在尝试使用 expex 对正文进行行间注释，其中正文采用 RL 语言（阿拉伯语），而自由文本采用 LR 语言（英语）。从输出中可以看出，RL 语言格式正在接管自由文本的格式。如何让 expex 仅对自由文本使用 LR？

输出：

Answer 1

添加\textenglish{...}将解决 RL 问题。

\glft \textenglish{My name is Haisham Najjar. I am a student in the college of science at Damascus University.}

编辑：也添加到everyglft=\raggedleft了lingstyle。
