word_count() won't work inline in quarto documents

[silverfoxdoc]

word_count() doesn't currently work with quarto documents when it is used inline, see reprex below. It does however give a word count if the same qmd document is passed to it directly though word_count("reprex.qmd")

Gives this error:

Quitting from lines 11-16 (reprex.qmd)
Error in `text_to_count()`:
! The supplied file has an extension which is not associated with markdown.
  This function only works with markdown or R markdown files.
Backtrace:
 1. wordcountaddin:::word_count()
 2. wordcountaddin:::text_to_count(filename)

Execution halted

Is this fixable?

---
title: "reprex"
format: pdf
---

```{r}
#| label: libraries

library(wordcountaddin)

Word Count: r wordcountaddin:::word_count()

Right, that usage is currently not implemented (it also wont work like that for R Markdown documents). An immediate fix to get that working is to include the path to the file in the function, as you note, like this:

---
title: "reprex"
format: pdf
---

```{r}
#| label: libraries

library(wordcountaddin)

Word Count: r wordcountaddin:::word_count('my_reprex.qmd')

Which gives this output:
