Description

In a presentation, i want to want to include a slide which is in another directory by using its path: "DIRECTORY_TO_SLIDE"

How can i write this in a variable or meta so i don't have to write the entire "DIRECTORY_TO_SLIDE" every time?

Thank you for the help you can provide,

---
title:   my title
author:  my name
format:  revealjs
---

## First slide
- with some text content

{{< include <DIRECTORY_TO_SLIDE>/slide1.qmd >}}

{{< include <DIRECTORY_TO_SLIDE>/slide2.qmd >}}

## Last slide
end of slides

You can't do that with an include shortcode. You can use a Lua filter to do it, though.

Thank you for your answer.
I'll investigate into the Lua filter solution, for I've never used it before.
Thank you!

I tried with the Lua filters, but no success.
Where is the error?

## First slide

<!-- this does not work -->
{{path_to_slide}}

<!-- this does work -->
{{< include ./utils/slide.qmd >}}

## Last slide
end of slides

pathfinder.lua

path1 = "./utils/"

function Str(el)
   if el.text == "{{path_to_slide}}" then
      el.text = "{{< include " .. path1 .. "slide.qmd >}}"
   end
   return el
end
