Many thanks for the new upload, Hans. I have just tested this feature and I really like it. Pablo

I have crude macros which provide this features (save stuff in boxes and then unbox) for showing stuff stepwise in presentation (without relying on fancy PDF features which are viewer dependent). So, this new feature is very interesting. Thanks! I use stackers in the following ways: Case 1: Show stuff step by step \startstackingsteps[1,{1,2},{1,2,3},{1,2,3,4}] \startstacking[1] ... \stopstacking \startstacking[2] ... \stopstacking \startstacking[3] ... \stopstacking \startstacking[4] ... \stopstacking \stopstackingsteps Case 2: Show stuff step by step but some things are only shown once \startstackingsteps[1,{1,2,2only},{1,2,3},{1,2,3,4}] .... \startstacking[2] % Show always after 2nd step ... \stopstacking \startstacking[2only] % Show only during step 2 ... \stopstacking ... \stopstackingsetps Case 3: Show stuff step by step but some things are only for specific slides \startstacking[2only,3only] % Show only during step 2 and 3: ... \stopstacking So, I have a few requests: 1. Can we add support for \startstacking[one,two]? 2. For case 1, could we have a shortcut to easily write \startstackingsteps[1,{1,2},{1,2,3}...]. This gets really tedious when there are say 6 or 7 steps. One option is: \startstackingsteps[criterium={1,2,3}, alternative=normal] % or sequential for the current implementation and \startstackingsteps[criterium={1,2,3}, alternative=cumulative] for the cumulative option (1,{1,2},{1,2,3}...) 3. It will be nice to have a syntax to easily handle case 2 and 3.

Very nice, thank you! I see some similarities to the "visible on" technique [1], I posted in a previous thread. What comes there really handy are range specifiers, what seems not possible with this interface. For example: "visible on=<2->" renders the content on every page except the first one or "visible on=<1-5,13-15>" on the first page up to the fifth page and from page 13 to 15. The mechanism stems from the Beamer overlay specifications, see section 9.3 of the manual [2] and can be much more complicated with modes (section 9.6.2). To add this to the new interface, if you want that, the stack layers above need some kind of order, which is implicit for numbers: ``` \definestacking{one} \definestacking{two} \definestacking{three} \definestackingorder{one,two, three} ... \setupstacking[criterium={one-three}] ``` The order could also be implicitly defined after the order of the \definestacking calls. Or would it be possible to have numbers always automatically (additionally) available as stacking layer? So that this "just" works: ``` \startbuffer This is a test \stacking [1] {and a proof} of \stacking [2] {concept} indeed. \stopbuffer ... \setupstacking[criterium={1-}] ``` I also wondered, if it is possible to define a lot of layers semiautomatically in Lua (in some graphics I needed around 20 layers). It seems that numbers in layer names currently are not allowed. Is code like this possible somehow? ``` \startluacode for i = 1, 20 do context.definestacking(string.format("l\letterpercent.d", i)) end \stopluacode ``` Gerion [1] https://github.com/luhsra/texmf/blob/main/tex/latex/beamertools/beamertools....

I need to correct myself (I had a typo in my tests before). Numbers as stacking layer names are possible. This Lua code works fine: ``` \startluacode for i = 1, 20 do context("\\definestacking[l\letterpercent.d]", i) end \stopluacode ``` Gerion

I don't know beamer other than seeing presentations at meetings but I assume that it has some accumulator. We do have steppers in mkii / mkiv already in the presentation styles. The conceptual cleanest of them depends on the viewer and free ones never catched up so that one is acrobat specific. The stacker discussed now is just similar to the metapost one but then at the tex end. (A quick hack with room for more a bit more effiency if ther ei sneed for it.)
