#pause breaks easily

[KronosTheLate]

Example 1

#polylux-slide[
first #pause

second #pause

- third #pause

- fourth #pause

- fifth #pause
- sixth
]

Below I made a table of what appears on what subslide:

subslide	new content
1	"first"
2	"second" through "fifth"
3	"sixth"
4	nothing
5	nothing
6	nothing

The troublesome part is that any pair of lines (1 and 2, or 3 and 4, or 5 and 6) produce the expected output.

Example 2

#polylux-slide[
  first #pause
  second
]

subslide	new content
1	"first second"
2	nothing

This is warned about in the documentation. But the problem is that the only pause in the code is between the content, but happens in the end. I believe this is the effect that goes wrong many times in example one, where any "untrigger" #pause is just collected until the end, and used then.

Desired/Target behaviour

Below I collected a couple of "rules" that I would like the #pause command to follow:

• New subslides without new content can not be produced by #pause commands with content between
• If there is a #pause between any two pieces of content, both pieces can not appear on the same subslide

If we agree that this would be ideal and technically possible, I think that these rules could serve as a good reference of what the behaviour should be.

This one is fixed

Example 3

#polylux-slide[
  #set text(15pt)
  - 1 #pause
  - 2 #pause
  - 3 #pause
  - 4 #pause
  - 5 #pause
  - 6 #pause
  - 7 #pause
  - 8 #pause
  - 9 #pause
  - 10 #pause
  - 11 #pause
  - 12 #pause
  - 13 #pause
  - 14 #pause
  - 15 #pause
  - 16 #pause
  - 17 #pause
]

Stops producing sub-slides after 10. After that, the rest of the content is simply ignored.

This is due to an old limitation of Polylux that is fixed on main.

Awesome! That is great to hear. i only came here to say that I see that this aspect is documented under "internals", but having it be a non-issue is even better than having it documented. Thanks!

Example 3

Code:

#polylux-slide[
  *Manual heading* #pause

  - New line #pause

  - Second line
]

subslide	new content
1	"Manual heading"
2	"New line" and "Second line"
3	nothing
4	nothing

So not only are both bullets revealed on the same subslide, despite a #pause between, but there are 4 subslides as a result of 2 pauses.

The results are the same if I remove the blank line between each line, and if I remove blank lines and add \ after the manual heading line.

This is due to an old limitation of Polylux that is fixed on main.

I am unable to set max-repetitions for #slide (as is explicitly recommended here. I just wanted to mention is, as there is no workaround until a new version is tagged (other than using the main branch).

[andreasKroepelin]

It's an argument to #polylux-slide. On main, this is gone anyways.

Example 4

This issue is related to using pause both inside and outside #side-by-side at the same time.

If I only use #pause inside, it works as expected:

But when I add a pause after the first line, I get no transitions:

[andreasKroepelin]

Yeah i think nesting overlay functions should not be done 🤔

[KronosTheLate]

I was thinking that because #side-by-side only changes layout, it changes to subslides should be orthogonal. But perhaps not...

Sorry for giving you a headache, and thanks for putting up with me. If this turns out to be fruitful, Polylux will certainly be more battle-tested xD

[KronosTheLate]

The first 3 examples just work as expected using Touying, with the following code:

#import "@preview/touying:0.2.0": *
#import "@preview/pinit:0.1.3": *

#let s = (s.methods.enable-transparent-cover)(self: s)
#let (init, slide, slides, uncover, only, alternatives) = utils.methods(s)
#show: init

//#show: slides

#slide[
first #pause

second #pause

- third #pause

- fourth #pause

- fifth #pause
- sixth
]

#slide[
  first #pause
  second
]

#slide[
  *Manual heading* #pause

  - New line #pause

  - Second line
]

The last example can not be reproduced because there is no #side-by-side function in touying. Would it be possible to take inspiration from how toying implement #pause? I am not at all sure about the implications for internal structure, but it seems to "just work", which is fantastic.
