wrong page for annotation and \pagenumber

wrong page for annotation and \pagenumber

[Pablo Rodriguez]

Dear list,

I have the following number with wrong annotation placement and wrong
page number, which would be both on the second page:

  \setupinteraction[state=start]
  \definelayer[pgnumber]
  \setupbackgrounds[page][background=pgnumber]
  \starttext
  \placelist[section][alternative=d]
  \dorecurse{16}{\section{Section}}
  \pagenumber/\lastpagenumber
  \setlayer[pgnumber]
    {\comment{\pagenumber}}
  \stoptext

Could anyone confirm the issue?

Many thanks for your help,

Pablo

\pagenumber is only reliable headers/footer texts or page backgrounds, 
for everything else you need a multi pass mechanism (save the page 
number in the first run and provide it in the second).

\setuppapersize[A6]

\definepagestate[pagenumber]

\starttext

\subject{\tex{pagenumber}}

\dorecurse{50}{\twodigits{\recurselevel}: \pagenumber\par}

\page

\subject{\tex{pagestaterealpage}}

\dorecurse{50}
   {\twodigits{\recurselevel}:
    \setpagestate[pagenumber]%
    \pagestaterealpage{pagenumber}{\recurselevel}\par}

\stoptext

Many thanks for your reply, Wolfgang.

I thought this was caused by the deployment of
"\placelist[section][alternative=d]". But my new sample shows clearly
that this isn’t the cause.

My question is now is how to get the right page for the layer in this
sample:

  \definelayer[whatever]
    [x=3em, y=3em]
  \setupbackgrounds[page][background=whatever]
  \starttext
  \dorecurse{18}{\section{Section}}
  just a line
  \setlayerframed[whatever][foregroundstyle=\bf\ss]
    {layer on the last page?}
  \stoptext

Many thanks for your help,

Pablo

Hi Pablo,

I fear I don't understand what issue you mean, therefore I append my output here.

I'm using:
LuaMetaTeX, Version 2.04.02
ConTeXt  ver: 2020.02.17 19:36 MKIV beta  fmt: 2020.2.23

Best wishes,
Rudolf

Many thanks for your reply, Rudolf.

The issue is that the layer is placed on the first page, where it should
be placed on the second page.

This sample shows thie problem in a simpler way:

  \definelayer[whatever]
    [x=3em, y=3em]
  \setupbackgrounds[page][background=whatever]
  \starttext
  \dorecurse{18}{\section{Section}}
  just a line
  \setlayerframed[whatever][foregroundstyle=\bf\ss]
    {layer on the last page?}
  \stoptext

I’m afraid that you get the same result, so there may be a bug there.

Many thanks for your help,

Pablo

\setuphead
   [section]
   [before={\testpage[2]\blank[2*big]}]

There is no bug. When you take a look at my pagenumber example you see a 
few lines at the top show the number of the previous page, this happens 
because TeX collects more than necessary which means in your example 
above the layer is placed when TeX was still on the first page.

In your example you can add \testpage to \section to force a page break 
when there isn't enough space available to place the heading, this moves
also the layer placement to the next page.

Many thanks for your reply, Wolfgang.

I’m afraid that TeX is too tricky for me in that case (or I simply think
that it is misbehaving there).

I’m afraid this doesn’t work with my real document.

I need another approach. This sample reflects my problem:

  \setupinteraction[state=start]
  %~ \showframe\showgrid
  \starttext
    \dorecurse{41}{one line\par}

    \ \comment[location={rightmargin}]{comment}
  \stoptext

Since layers are problematic for the task, I insert the comments right
after the text (which actually comes from \xmlflush{#1} [XML sources]).

I’m afraid that the paragraph before \comment comes from \xmlflush, so I
cannot avoid it.

This is unproblematic for most cases, but the sample above displays the
problem of adding a comment in a new paragraph. It might add a new page.

To avoid this issue: how could I prevent the pagebreak before \comment
and the addition of a pagebreak above?

If that were possible, I could add a \blank[-2*line] that would place
the comment right.

Many thanks for your help,

Pablo

Try

\removeunwantedwhitespace

or

\blank[samepage]
