Find the name of the current file being rendered in Quarto

I don't think we have the information stored and available from within Quarto - Maybe we could make this available in Variables system (Quarto – Variables)

The idea is tracked in

There is a Lua workaround there.

For current workaround, I am thinking of two thinks R specific

  • knitr has knitr::current_input() function. This will return the filename of the input being knitted. You won't get the original filename because it gets processed by Quarto and an intermediate file is passed to knitr but it is just a matter for extension so this would give you the filename

This is written in test2.qmd

---
format: html
---

The input `.qmd` file for this output is `` `r xfun::with_ext(knitr::current_input(), "qmd")` ``

It returns this
image

  • Using quarto::quarto_render() and leveraging parameters

test.qmd document

---
format: html
params:
  input_file: ""
---

The input `.qmd` file for this output is `` `r params$input_file` ``

rendered using

input <- "test2.qmd"
quarto::quarto_render(input, execute_params = list(input_file = input))

You see the idea I believe on how using params can help you pass information from R to knitr.

Hope it helps
