How Can I Get the Text Direction of the current language?

Questions
1

I need to check whether the text is being laid out rtl or ltr. In other words, I need to know whether the current language is written ltr or rtl.
If I do

context text.dir

I get auto.
How can I get rtl or ltr?

I can check it using text.lang, but then I’ll need to have the list of all rtl languages, which seems inconvenient.

I also faced this problem before Add default typst implementation code where possible · Issue #5095 · typst/typst · GitHub. You probably should open an issue about this.

// crates/typst-library/src/text/lang.rs
#let get-text-dir() = {
  if text.dir != auto { return text.dir }
  let rtl-langs = (
    "ar",
    "dv",
    "fa",
    "he",
    "ks",
    "pa",
    "ps",
    "sd",
    "ug",
    "ur",
    "yi",
  )
  if text.lang in rtl-langs { rtl } else { ltr }
}

// #set text(dir: rtl)
// #set text(lang: "pa")
#context get-text-dir()

Also, please use the appropriate language identifier for code block in forum posts, as explained in How to post in the Questions category.
