Beamer overlays in notes

[Eloitor]

Describe your proposed improvement and the problem it solves.

When exporting to beamer, we can add speaker notes, which pandoc translates as \note{ my note }, like this:

::::: notes ::::::
my note
::::::::::::::::::

I would like to have support for something which translates to \note<1>{ my first note}. I know that this syntax is currently supported 8d7ecc2 , but I think it would be nice to have something like

::::: {.notes only=1} :::
my first note
:::::::::::::::::::::::::

Describe alternatives you've considered.

I did a pandoc filter to do this, but I need to change "notes" to "note", otherwise the div is beeing parsed twice.

function Div(el)
    if el.classes[1] == "note" then
      -- insert element in front
      if el.attr.attributes["only"] then
        table.insert(
            el.content, 1,
            pandoc.RawBlock("latex", "\\note<" .. el.attr.attributes["only"] .. ">{"))
      else
            table.insert(el.content, 1, pandoc.RawBlock("latex", "\\note{"))
      end
      -- insert element at the back
      table.insert(
        el.content,
        pandoc.RawBlock("latex", "}"))
    end
    return el
  end

• Is it possible to fix this filter to work well with "notes" directly?
• Does it make sense to include this feature in pandoc? Does it have any drawback?

Here's my try to make the filter work with "notes":

function Div(el)
  -- Only handle note divs that should appear on specific slides.
  -- We rely on pandoc to handle other notes.
  if el.classes[1] ~= "notes" or not el.attr.attributes.only then
    return el
  end

  return
    {pandoc.RawBlock("tex", "\\note<" .. el.attr.attributes.only .. ">{")} ..
    el.content ..
    {pandoc.RawBlock("tex", "}")}
end

Does it work the way you had in mind?

[Eloitor]

Thanks! this is it.
By the way, why is this feature called "notes" and not "note" in pandoc?

Seems like a good addition to the LaTeX writer.
I don't recall about the name, sorry!
