Create a single revealjs presentation from multiple qmd files

[m-guggenmos]

Description

I would like to combine a set of qmd files into a single revealjs presentation. What would be the easiest way to achieve this in Quarto?

Currently my _quarto.yml looks something like this:

project:
  output-dir: _slides
  render:
    - slidedeck1.qmd
    - slidedeck2.qmd
    - slidedeck3.qmd

format:  revealjs

.. and as a result I want a single slide deck comprising slidedeck1.qmd to slidedeck3.qmd.

You could use includes to add content of several files into a main file: https://quarto.org/docs/authoring/includes.html

But this suppose your individual file are fragment of a main presentation.

If each file is a single slidedeck at the beginning, you may need some preprocessing or using some Lua filters to adapt content.

Anyhow, there is no project options as you tried to merge document into one. What you configured for now tells quarto to:

• Render each file using revealjs format by default
• Only render the file passed to render:
• Put the output of each render into output_dir

Hope it helps

This is expected as the include shortcode is basically a copy/paste.
https://quarto.org/docs/authoring/includes.html#overview

It's not about footnotes identifiers, but any identifiers as the following will cause trouble.
Same goes for any YAML frontmatter set.

## Section 1 from document 1 {#sec-one}

## Section 1 from document 2 {#sec-one}

Thanks for your reply. Looking forward to the solution in the future. @cderv

I found this Lua filter to include other files in the document written by @tarleb.

I have tested this Lua filter and it managed to avoid conflicts of the same identifiers in multiple files. However, the issue is that code chunks in Quarto files cannot be executed. I have submitted an issue about it but there is no replies yet. Do you have any ideas about this?

[cderv]

@TomBener the non execution part is not an issue about the Lua filter there. The lua filter step will happen too late, after the execution.

This is why we have the include shortcode syntax: https://quarto.org/docs/authoring/includes.html

Did you identify what is the difference about this filter ? It is possible it "avoid" conflicts because the include may happens after any identification / resolution of the feature associated with the conflict seen ( too late ?).

This could work in some cases, but obviously some quarto feature won't work as you noticed because they require to be process before Pandoc. Like the code execution.

Are you still trying to handle the duplicate note reference warning ? Or is this for something else ?

[TomBener]

Thanks for your explanation. I do need an approach to avoid duplicated footnote and reference-style link identifiers in multiple files like the file-scope feature in Pandoc. I have tried many ways but they didn't work as expected, even though I have tried the book project in Quarto.
