Animate paragraphs/text line by line

[alinush]

Hi,

I was just giving Marp a try: it looks like the perfect solution for doing slides quickly.
Unfortunately, I can't figure out how to "animate" the text on each slide.

I'm not looking for anything fancy. I just want to be able to gradually introduce the text on the slide, line by line to the audience. I don't want to display the full slide with the whole text, because it's too much information at once. This will distract the audience, in my experience.

Is there a way to do this in Marp? I apologize if this is trivial. I searched in the marp-core & marpit issues, and on the https://marp.app/ and https://marpit.marp.app/ websites.

In particular, is there a way to animate the equations in begin{aligned} one by one? (Once again, displaying a block of 10 equations to the audience is not a good idea in my experience.)

Thank you,
Alin

Later edit: I am basically looking for something like \pause in Beamer or like "pauses" in pandoc's presentation mode

Refer to marp-team/marpit#195 and marp-team/marpit#209.

The most similar solution you wanted is fragmented list in Marpit.

* $x=a+b$
* $x=a+b+c$
* $x=a+b+c+d$
* $x=a+b+c+d+e$
* $x=a+b+c+d+e+f$
* ...

<style scoped>ul { padding: 0; list-style: none; }</style>

<style scoped> is required to hide bullets on the regular list.

An another way is wrapping math in HTML that is assigned data-marpit-fragment attribute (explained in marp-team/marpit#195). It's a way similar to reveal.js fragments and suited to pause more flexible contents. Notice that it's advanced usage and Marpit does not yet recognize them correctly

Thank you. I unfortunately missed the "fragmented list" when I skimmed the documentation.

Hacking equation animation with bulletpoint lists will work for most things, but I don't think it'll work for certain aligned blocks like this one:

\begin{aligned}
a + b &= c + d\\
    a &= c + d - b
\end{aligned}

Unfortunately Marp team has no ones familiar to TeX (KaTeX) so we have no idea how to use advanced fragments within math syntax.

For contributor: Marpit fragments is not flexible as much as Beamer, but nevertheless extending macro for using Marpit fragments in Marp Core's math plugin may help.
