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. 

As a bonus, I found that tex stacking plays nicely with metapost stacking!

\starttext

\definestacking[1]
\definestacking[2]
\definestacking[3]

\startbuffer
\subject{How to draw a circle}
\startitemize
\startstacking[2] \startitem Pick a point \stopitem \stopstacking
\startstacking[3] \startitem Draw the circle \stopitem \stopstacking
\stopitemize

\startplacefigure[location={here,none}]
  \startMPcode[stacking={\namedstackingparameter\empty{criterium}}]
newpair A; A := origin;
newpath p; p := fullcircle scaled 3cm shifted A;

fill fullcircle scaled 3bp shifted A withstacking 2;

draw p withstacking 3;

setbounds currentpicture to bbox p ;
  \stopMPcode
\stopplacefigure
\stopbuffer

\startstackingsteps[1,{1,2},{1,2,3}]
 \startTEXpage[offset=1ts]
 \getbuffer
 \stopTEXpage
\stopstackingsteps
\stoptext

Aditya

[NTG-context] Re: Trouble installing on Alpine Linux

[Bryan Kaplan via ntg-context]

I tried manually specifying this format file, but then get this error:

```
$ context 
--fmt=/opt/context/tex/texmf-cache/luametatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/formats/luametatex/cont-en.fmt
 /tmp/test.tex
startup error : missing find_format_file callback
```

So I'm no longer convinced installation fully succeeded.

Sincerely,
Bryan Kaplan

To elaborate, I get the same error when attempting the test suggested in the 
installation instructions.

```
$ context /tmp/test.tex
startup error : no format file given, quitting
```

…maybe, that is. The installer finished up by informing me:

But attempting that first command gives me, “startup error : no format file

file, and if so which?

i installed an alpine on WSL to see what happens

- it looks like some 32/64 bit mixup ... this is a side effect of the 
fact that it take a bit of effort to see if we need musl


- the buildbot doesn't generate the binaries (i can't login to the 
machine to check if the client is running at all)


i'll see what i can do (will give some upload noise on the list)

btw, i can compile luametatex on WSL alpine so i can use that binary

you can do that as exercise:

- apk add build-base
- apk add cmake
- go to tex/texmf-context/source/luametatex
- chmod 755 build.sh
- ./build.sh
- copy bin from build/native

Many thanks for the new options, Hans.

Sorry, but I don’t know how I would have to use \define here instead of
my macros.

BTW, I created them long time ago to avoid having two commands (one to
contain the address and another to typeset it), such as in (copied from
the wiki):

  \useURL[anotherurl] [http://xkcd.com/224/]

  \from[aurl] % typesets the URL

[NTG-context] weekend update

[Hans Hagen via ntg-context]

Hi,

I uploaded a new version:

-- fix for hraban's svg image (one character patch)

-- more verbose link comments for pablo (for experimenting)

-- support for stacking at the tex end (maybe for presentations)

\starttext

\definestacking[one]
\definestacking[two]

\startbuffer
This is a test \stacking [one] {and a proof} of \stacking [two] 
{concept} indeed
\stacking [one] {\blackrule [width=4cm]} is it and the question is how 
\stacking

[two] {\scale [s=2] {fancy}} we can go

\startstacking[one]
\startformula
\sqrt{1+x}
\stopformula
\stopstacking

and how useful \stacking[two]{\inframed{it}} is.
\stopbuffer

\startstackingsteps[one,two,{one,two}]
\startTEXpage[offset=1ts]
\getbuffer
\stopTEXpage
\stopstackingsteps

\startTEXpage[offset=1ts] \setupstacking[criterium={one}] \getbuffer 
\stopTEXpage
\startTEXpage[offset=1ts] \setupstacking[criterium={two}] \getbuffer 
\stopTEXpage
\startTEXpage[offset=1ts] \setupstacking[criterium={one,two}] \getbuffer 
\stopTEXpage


\stoptext

-- support for more private pdf

\enabledirectives[backend.pdf.nounicode=noai]
\enabledirectives[backend.pdf.nounicode=nopilot]
\enabledirectives[backend.pdf.nounicode=justread]
\enabledirectives[backend.pdf.nounicode=✅]
\enabledirectives[backend.pdf.nounicode=✅❌]
\enabledirectives[backend.pdf.nounicode=❌]

\startTEXpage[offset=1ts]
\input tufte
\stopTEXpage

The last option can be handy when you don't want to make harvesting your 
documents too easy for these ai bots (as in cloud based pdf stuff). It's 
the first outcome of the multi-year, multi-stage, very scientific 
'inacessible pdf' project that Mikael S. and I recently started.

At least, I would like to be sure what is going on here.

Hovering over links is basic precaution before clicking them.

To explain that to others, I’d rather know how Acrobat (Reader) behaves
in these cases.


Build 24.2.20857.0 on MacOS 10.15.7:

Many thanks for your help, Hraban.

Thanks to your confirmation, I investigated the issue further (since
there had to be something different with my documents).

\setuptagging[state=start] is the culprit. "link" is the word displayed
when links are hovered over.
It's not that hard to get something less generic displayed but the 
question is what and in what detail. A lot of this stuff is not 
consistent over viewers and it being part of the user interface might 
also change over time (some viewers also interpret the page stream for 
urls).


Anyway, a next upload will have this:

% \disabledirectives[backends.references.descriptions]   % just link
% \enabledirectives [backends.references.descriptions]   % some 
detail (some todo) (default)
% \enabledirectives [backends.references.descriptions=reference] % a bit 
less


so that you can experiment a bit with it. We might at some point provide 
optional descriptions per link but the quesiton is how to cleanly 
interface this (easier if you use \define... instead of your own macros 
for urls).

I got some understanding of the underlying code now.
This setup solves the above issue:

```
\startsetups btx:aps:cite:special
% just a dummy
\fastsetup{btx:cite:concat}
\btxcitereference
\currentbtxtag
\stopsetups
```

I have found entries on \widowpenalty, \widowpenalties, \orphanpenalty,
\orphanpenalities and look forward to learning about vertical expansion.
Many thanks, Hans.

Hi,

I'm using LaTeX-Beamer and TikZ for figure typesetting.

If you use that kind of simple graphics, you can avoid this transparency
hacking by using metafun:

\setupbodyfont[dejavu]

\starttext

\startuseMPgraphic{test}
  pickup pencircle scaled 2mm ;
  draw fullcircle scaled 3cm withcolor darkred  withstacking 1 ;
  draw fullcircle scaled 2cm withcolor darkblue withstacking 2 ;
  draw textext("one")   withcolor darkgreen withstacking 11 ;
  draw textext("two")   withcolor darkgreen withstacking 12 ;
  draw textext("three") withcolor darkgreen withstacking 13 ;
\stopuseMPgraphic

\startTEXpage[offset=.25ts]
  \useMPgraphic{test}{stacking={1,11}}
\stopTEXpage

\startTEXpage[offset=.25ts]
  \useMPgraphic{test}{stacking={2,12}}
\stopTEXpage

\startTEXpage[offset=.25ts]
  \useMPgraphic{test}{stacking={1,2,13}}
\stopTEXpage

\stoptext

It's an already old feature but probably not that well known. If needed
I can make something similar at the tex end.

Hans


Thank you for the example, but learning metafun is another chapter and the
graphics are much more complicated than the minimal example given.

I saw that you pushed an updated version that fixes the bug [1]. Thank you!

The next upload will have an example of something similar at the \TEX\ 
end (i made it a few days ago but no upload yet). An exmaple can (then) 
be found in:


  stacking-001.tex

in the test suite.

[NTG-context] Re: (off-topic) hovering over links in Acrobat Reader

well it would imho be better not to use that at all. Sorry but what
context is doing here is cheating. It claims to add a structure (and
probably manage to pass automated tests) but all StructElem with the
exception of links are role mapped to NonStruct and so are non
functional. Links miss the OBJR reference. Annotations only all have
as /Content a generic text (link) (which creates your hover effect).  

When I let Adobe+NVDA read a PDF tagged with LaTeX it recognize and
announces structures:

headinglevel 2  A section
text
table  with 2 rows and 2 columns  
row 1  column 1  header A
   column 2  header B
row 2  header A  column 1  data A
   header B  column 2  data B
out of table
linkhttps://www.example.com

I can navigate from one heading to the next and inside tables (and
when I hover a link the pop up is correct as we are setting the
right Contents value.)

If you do the same with a document tagged with context you only get
a large blob of text

A section textHeader AHeader B data Adata B
https://contextgarden.net

and no navigation at all. All the tagging in the file is useless, it
even actually harms because it makes user believe they get an
accessible PDF. 

Tagged, accessible PDF has a lot of shortcomings, especially when it
comes to complex documents and math, but for standard documents it
can do much better then what context is making out of it.

Thank you Hans for documenting:
