[Feature request] Hide and Unhide PowerPoint Slides

[laresbernardo]

I've reviewed all the available documentation and haven't seen an option to hide or unhide a slide. This is a valuable functionality and I wouldn't expect it to be too complex to include in the package.

Use Case: I've included an appendix slide that contains the code to replicate the deck. There's no need to include this slide in a presentation but it's super useful to have in the deck.

Thanks for this amazing package!

How do you estimate that ? Do you have pointers that show how to implement it ?

[laresbernardo]

You are right, I don't. Sorry if that sounded rude. I extrapolated from the advanced functionalities I've seen already implemented in officer and thought it was a matter of finding the right "command" to hide and unhide slides. No foundations to back the comment. Hope it's not complicated though!

Technical

On a technical level, it appears that a slide is hidden (shown) by setting the show attribute in the p:sld node to 0 (1) (in the slide xml file).

<p:sld xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" 
xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" 
xmlns:p="http://schemas.openxmlformats.org/presentationml/2006/main" show="0">
...
</p:sld>

API

Does someone have a suggestion for the API? Some options could be:

• a visible arg in add_slide() which defaults to TRUE
• a new function slide_visible() to get and set a slide's visibility (e.g. hide and show arg taking slide indexes)

Examples:

add_slide(x, "Title Slide", visible = FALSE)

slide_visible(x)
[1] TRUE TRUE TRUE TRUE

slide_visible(x, hide = 2:3)
slide_visible(x, show = c(1,4))

slide_visible(x)[2:3] <- FALSE

@davidgohel Please feel free to assign this issue to me, if you find it is a suitable feature

@laresbernardo Out of curiuosity: Would you mind telling a bit more about your use case? I was never in a situation where I needed to generate hidden slides, when creating them programatically...

[laresbernardo]

@markheckmann of course, as I shared in my first comment, I'm generating a slide at the end of the deck that contains the code to replicate the deck. It also contains a full JSON formatted string with all the results (not shown in the nice slides but that may be useful). Given these decks I'm working on are ready to be pitched/shared, I wouldn't want them to be shown while presenting.

[davidgohel]

@laresbernardo in this use case, using comments/notes instead of hidden slide seems more relevant to me but it's only a point of view.

You can have a look at set_notes()
