I was already more convinced of keeping snap-to-grid turned off. Now
the problem is how to adjust the spaces around quotations (and floats)
at the minimum cost.

Since the line heights of the main text and the ones of quotations do
not change, the adjustment depends only on the number of lines of
quotations. I could compile a table for more common cases:

# of lines | adjustment
1 line | ... pt
2 lines| ... pt
3 lines| ... pt

20 lines   | ... pt

I should teach users how to insert adjustments, but the task would be
eased because they should only copy a value from a table or insert a
name that corresponds the the number of lines (i.e. "adjust-3-lines",
"adjust-4-lines", etc.)

Be careful not to insert an adjustment after a block that is split over 
two pages.


A more useful (from a user perspective, I do not know about the coding) 
solution would be a command to snap to the nearest grid line (up or 
down, half or whole step).


But both your count and my \snapto suffer from a common problem. Both 
are likely to leave different amounts of space before and after the 
block. A more evenly balanced approach is to compute the height of the 
block plus the vertical space by which it should be set off plus the 
vertical space needed to reach a grid-line or half-grid and, if the 
block stays on the page, split the difference top and bottom. If the 
block does not stay on the page, some portion with the top offset must 
be calculated and placed on the page if it otherwise meets widow/orphan 
tests.

[NTG-context] size of footnote numbers

2017-09-29 Thread Henning Hraban Ramm 
Ahoi,

in my current book there are some quotations typeset in a smaller type (via 
\switchtobodyfont in a defined startstop).

Now the author insists that their footnote numbers should have the same size as 
in the body text.
Since the footnotes are mostly source annotations at the end, it makes some 
sense.

What would be the best way to achieve this?

Here’s my setup:

\setupbodyfont  [alegreya,rm,11pt] % usual font size

\startsetups[myQuotation]
  \setupwhitespace[none]
  \setupnarrower[left=2em,right=2em]
  \switchtobodyfont[rm,10pt]
% I guess I should change the footnote number font size here?
\stopsetups

\definestartstop[myQuotation][
setups=myQuotation,
before={
  \testpage[2]
  \startnarrower[left,right]
  \noindent},
after={\stopnarrower
  \indenting[next]}]

Thank you Rik, I overlooked that (and now I'm reading Hans' reply about
line correction being for framed material and not for quotations).

I need to decide whether to 
- turn off grid snapping and adjust every single quotation 
or
- turn grid snapping on, benefit from line correction most of the time
and manually adjust the cases where a quotation is across a page
boundary

It depends on the texts I'm working on.

This question reminds me the chapter about line profiling in the
"Still" manual. There's no general, fully automated solution.

> It would be nice to have an alternative that does not have that

> 

Hans talked about that at the last ConTeXt Meeting. If I understand
well, it's very hard to calculate how much of the vertical space of the
page TeX has used. And once it flushes the page, it frees the memory
and forgets about it.
Add inserts like footnotes to the problem and it gets really hard.

Massi

But I have many quotations (and floats), whose spaces before and after
should be manually tuned not to push the main text out of the grid.
And here grid snapping does a very good (and automated) job.

But sometimes grid snapping is too strict, as in the tall formula
example. I'm still afraid it's too strict and it will hurt in other
places of the text, but now I have a solution, at least for that
problem.
So thank you again,

If you are really keen on screwing up your linespacing you can use

\vadjust{\blank[line]}%

as a one-off solution.  But better make it a displayed formula or
tweak it such that it does not
disrupt spacing and blends in with the text.  In this example I'd
change $\displaystyle\frac{1}{a +
b}$ to $(a+b)^{-1}$.  Trust someone who does math typesetting every
day.


\input knuth

Now the text snaps to the grid after the quotation, but the tall

The solution would be a grid configuration that gives the line
containing the formula two lines of height, putting that only line
in
the middle and then snapping the following lines again to the grid
(still solving the alignment of quotations as in the grid=both
case).
Is it possible?

If I prepend a \setuplayout[grid=yes], it works, but grid

I would like the halfline spaces before and after the quotation

Is there an automatic way to get the normal text "return" on

after a quotation without turning on a global grid snapping?


\setuplayout[grid=both] to round down both height and width when
snapping.

Hans,

after updating to latest beta (from 2017.09.25 19:19 to 2017.09.28 10:07

MuPDF-1.11 displays bookmarks (see attached image).

This is the GL version, I don’t know how to do that in the X11 version

If we have a sample PDF document, we may know what is broken there: the
viewer reading the bookmarks or the PDF document containing them.

Re: [NTG-context] synctex, TeXShop and \input files

2017-09-29 Thread Otared Kavian 
Hi Hans,

Thanks for the hint. Indeed every input file has got a reference in synctex 
file produced by ConTeXt. 
(I noticed also that during the typesetting ConTeXt creates another file with a 
suffix syncctx which is wiped out at the end of the processinng).

On the other hand after reading your hint I tried the same files with another 
application, TeXWorks, and there the syncing works perfectly. 
Therefore it seems that this is a problem with TeXShop and I am going to report 
a bug with Richard Koch.

Best regards: OK
