[NTG-context] vertical justification of mixedcolumns
Hello list,
in this MWE the columns are not aligned at the bottom, and they are not
at the bottom of the page:
\definevspacingamount[myBlank][5pt plus 5pt minus 2pt][5pt plus 5pt
minus 2pt]
\starttext
\showgrid
\startmixedcolumns[n=2,balance=yes]
\dorecurse{2}{\input knuth \blank[myBlank]}
Another paragraph to make columns uneven.\par\blank[myBlank]
\dorecurse{3}{\input knuth \blank[myBlank]}
\stopmixedcolumns
\stoptext
Is there a way to configure mixedcolumns so that \blank[myBlank] is
stretched or shrinked to get the two columns end aligned at the bottom
of the page?
Thanks in advance,
Massimiliano

Re: [NTG-context] Undesirable space with mixedcolumns
Hello,
I'm looking in the documentation and I think I found the key to remove the
white space under the mathematical formula.
Is this the best way to achieve optimal rendering using columns ?
Thank you

[NTG-context] Another issue with EBGaramond / firstline / mixedcolumns
Dear all, Trying to use EB Garamond font Inside mixed columns + use firstline feature (to make it larger) I get an empty line in output between first line and the rest of paragraph. If I comment the line containing \setupbodyfont and use default font the problem disappears (even with larger \tfa ratios well above 2). The problem seems only to happen when first line contains letters with space hanging below line base (like g or p for example). As well using columnset does not show the problem and using grid=verytolerant as well. Attached MWE + output.

Ok. It looks like the second parameter to \testcolumn is now required

no, more to making section breaks working better in columns (i forgot to

Re: [NTG-context] a way to implement \testcolumn in mixedcolumns
On 11/20/2013 10:47 PM, Lars Huttar wrote:
Hello,
On this list I've been advised that mixedcolumns is the latest and
greatest implementation of columns; the one to use. We have switched
over from columnsets to mixedcolumns, and have been very pleased with
the column balancing (for some reason we couldn't get column balancing
to work in columnsets).
However one thing we do miss from columnsets is the control over widows
& orphans in two ways: \testcolumn, and \setupcolumnsetlines.
\testcolumn[n] allowed us to do a conditional column break, so when we
were about to start a new subsection heading, we could prevent it being
an orphan at the bottom of the column; and when starting a paragraph
with a hangaround graphic framed flushright and bottom, we could
similarly use \testcolumn to prevent the graphic from hanging down into
the footer (which is what sometimes happened otherwise).
So I'm wondering, is there some way to achieve the equivalent of
\testcolumn in mixedcolumns?
Is it theoretically impossible to implement this in mixedcolumns because
the required information (how many lines are left in the current column)
is not yet known?
Or could that information be gleaned from somewhere?
I see in page-brk.mkiv the following definition for \testcolumn:
\def\testcolumn
{\dodoubleempty\page_tests_columns_test}
\def\page_tests_columns_test[#1][#2]%
{\endgraf
\ifdim\pagegoal<\maxdimen
\ifdim\pagetotal<\pagegoal
\d_page_tests_test\dimexpr
\pagegoal
-\pagetotal
\ifdim\lastskip<\parskip+\parskip\fi
\ifsecondargument+#2\fi
\relax
\getrawnoflines\d_page_tests_test % (raw)
\ifnum#1>\noflines
\column
\fi
\else
\penalty-\plustenthousand % (untested)
\fi
\fi}
I'm not a low-level TeX programmer, and I don't understand a lot of
this, but it looks like
\getrawnoflines\d_page_tests_test
puts the number of remaining lines into \noflines
Any suggestions are appreciated.
(And I should have a MWE soon.)
That macro was never meant for mixed columns. I made a variant that
works ok in mixed columns which will be in the next beta.

When I use the new beta (using 2013.11.26), marking works better, with
the following caveats:
1) The column number argument is required; using
\getmarking[country][top] instead of \getmarking[country][1][top] still
returns the wrong value. This is not a problem for us, but it's
important to know, because if you leave out the column number argument,
there is no error given, and AFAIR the documentation doesn't tell you
it's required.
2) Sometimes \getmark[country][n][bottom] returns the country at the top
of column n+1 (or column 1 on the next page). In your example above,
\getmarking[country][1][bottom] shows Peru, which is in column 2,
instead of Brazil. This can be a significant problem for us, unless we
can find a way to fix it.
Did you get a different result?

I tried this with your example above, but didn't see anything change.
Are we supposed to see some colored boxes around the marks?
Thanks again,

Hans, here is what I tried (MWE):
\setuppapersize[A4]
\starttext
\section{Introduction}
\startmixedcolumns[distance=5mm, balance=yes]
\dorecurse {25} {
\subsection{Subsection Heading}
\penalty1
If I had not participated fully in all these activities, literally
hundreds of improvements would never have been made, because I would
never have thought of them or perceived their importance. \endgraf
}
\stopmixedcolumns
\stoptext
As you see, I tried \penalty1 after the subsection heading.
But in the resulting PDF, on page 3, in the left column, we see a
subsection heading at the bottom of the column with nothing below it. So
something didn't work.
Am I not doing it the way you meant?
Thanks for your help,
Lars

In the same place we used to use \testcolumn? According to http://www.tug.org/utilities/plain/cseq.html#penalty-rp, "If is 10,000 or larger, TeX will never break a line or a page there. Also, if is -10,000 or less, it will always break a line or a page there [97 and 110]. ... Plain TeX has \break and \nobreak macros which are defined to be: \penalty-1 and \penalty1." So it sounds like you're recommending the equivalent of a \nobreak. That wouldn't make sense in the place where we want to conditionally break the column. So I guess you're talking about using it e.g. right after the subsection heading, since we don't want it to break right there? If so, that sounds like it will be helpful for preventing that particular case. I don't think it will work for preventing external figures from hanging down below the bottom of the column though, will it? Because for that to work, we'd have to prevent breaks anywhere in the flowing-around paragraph. And I don't see a way to do that.

You can see that the heading for subsection 6 is an orphan at the bottom
of a column (at least, with the paper size settings I have; otherwise,
I'm sure it happens somewhere else). If \testcolumn worked, the
\testcolumn[8] would have shoved the subsection heading to the next
column, because there was not space for 8 lines left in the column at
that point.
Any thoughts on how to fix this kind of occurrence?

I now have a MWE that shows the problem.
Where top and bottom work fine outside of columns, in mixedcolumns, any
keyword I use with \getmarking always seem to return the *last* item on
the page. Here's the MWE:
\definemarking[country]
%\startsetups myheader
%F1: \getmarking[country][1][first] - L2: \getmarking[country][2][last]
%\hfill
%T1: \getmarking[country][1][top] - B2: \getmarking[country][2][bottom]
%\stopsetups
\startsetups myheader
F: \getmarking[country][first] - L: \getmarking[country][last]
\hfill
T: \getmarking[country][top] - B: \getmarking[country][bottom]
\stopsetups
\setupheadertexts[\setups{myheader}][][][\setups{myheader}]
\def\anothersection#1{
\marking[country]{#1}
{\bfb #1 \endgraf}
\dorecurse{1}{\input knuth \endgraf}
\marking[country]{#1}
}
\starttext
\startmixedcolumns[distance=5mm, balance=yes]
\anothersection{Brazil}
\anothersection{Suriname}
\anothersection{Uruguay}
\anothersection{Bolivia}
\anothersection{Venezuela}
\anothersection{Peru}
\stopmixedcolumns
\stoptext
When you run the MWE, you see that all the fields in the page header
show the same value: whatever country appears last on the page. (Or
even, depending on how you tweak the length of the country text, if the
next page starts with a new country, you'll get that new country for the
old page.)
I also tried using column numbers, in imitation of the columnsets
example on the wiki at http://wiki.contextgarden.net/Command/getmarking
\startsetups myheader
F1: \getmarking[country][1][first] - L2: \getmarking[country][2][last]
\hfill
T1: \getmarking[country][1][top] - B2: \getmarking[country][2][bottom]
\stopsetups
But this didn't appear to make any difference. Maybe it works for
columnsets but not for mixedcolumns. Does anyone know how to get correct
results for \getmarking in mixedcolumns?
Thanks,
Lars

[NTG-context] a way to implement \testcolumn in mixedcolumns
Hello,
On this list I've been advised that mixedcolumns is the latest and
greatest implementation of columns; the one to use. We have switched
over from columnsets to mixedcolumns, and have been very pleased with
the column balancing (for some reason we couldn't get column balancing
to work in columnsets).
However one thing we do miss from columnsets is the control over widows
& orphans in two ways: \testcolumn, and \setupcolumnsetlines.
\testcolumn[n] allowed us to do a conditional column break, so when we
were about to start a new subsection heading, we could prevent it being
an orphan at the bottom of the column; and when starting a paragraph
with a hangaround graphic framed flushright and bottom, we could
similarly use \testcolumn to prevent the graphic from hanging down into
the footer (which is what sometimes happened otherwise).
So I'm wondering, is there some way to achieve the equivalent of
\testcolumn in mixedcolumns?
Is it theoretically impossible to implement this in mixedcolumns because
the required information (how many lines are left in the current column)
is not yet known?
Or could that information be gleaned from somewhere?
I see in page-brk.mkiv the following definition for \testcolumn:
\def\testcolumn
{\dodoubleempty\page_tests_columns_test}
\def\page_tests_columns_test[#1][#2]%
{\endgraf
\ifdim\pagegoal<\maxdimen
\ifdim\pagetotal<\pagegoal
\d_page_tests_test\dimexpr
\pagegoal
-\pagetotal
\ifdim\lastskip<\parskip+\parskip\fi
\ifsecondargument+#2\fi
\relax
\getrawnoflines\d_page_tests_test % (raw)
\ifnum#1>\noflines
\column
\fi
\else
\penalty-\plustenthousand % (untested)
\fi
\fi}
I'm not a low-level TeX programmer, and I don't understand a lot of
this, but it looks like
\getrawnoflines\d_page_tests_test
puts the number of remaining lines into \noflines
Any suggestions are appreciated.
(And I should have a MWE soon.)

[NTG-context] Mixedcolumns maximum height for vertical rule: bug?
Hi,
The horizontal rule for the first page extends to the bottom of the page,
but does not do so on the second page. How do you prevent the vertical rule
from extending to the bottom of the page?
\usemodule[ipsum]
\setuplayout[
topspace=\zeropoint,
height=fit,
width=fit, % Allow text to be flush with the bottom.
%footerdistance=2cm,]
\definemixedcolumns[StyleColumns][
frame=off,
separator=rule,
rulecolor=black,
alternative=global,
%maxheight=\textheight,]
% Set up two-column mode for the ingredients, instructions,
etc.\setuphead[section][
after={\startStyleColumns},
aftersection={\stopStyleColumns},]
\def\StylePageNumber#1{%
{\inframed[
frame=off,
background=color,
backgroundcolor=red,
width=2em,
height=2em,
]{#1}}}
\setuppagenumbering[location=inright,command=\StylePageNumber,]
\starttext\startchapter[title=Chapter]
\startsection[title=Section]
\input knuth \input zapf \ipsum \input knuth \input knuth \input zapf
\stopsection\stopchapter\stoptext

[NTG-context] Limitation of mixedcolumns?
The "nested mixedcolumns" does not work properly when it reaches the
bottom of the "outer mixedcolumns" here:
$ context --version
mtx-context | ConTeXt Process Management 0.60
mtx-context |
mtx-context | main context file:
d:/ConTeXt/tex/texmf-local/tex/context/base/context.mkiv
mtx-context | current version: 2012.07.24 15:58
here is the minimal example (mostly copied from page-mix.mkiv
===
\setupbodyfont[5pt]
\starttext
\setupmixedcolumns
[boxedcolumns]
[n=2,
balance=no]
\definemixedcolumns
[nestedboxedcolumns]
[boxedcolumns]
[n=2,
background=color,
backgroundcolor=yellow,
color=red,
strut=yes,
balance=yes,
backgroundoffset=0mm]
\startboxedcolumns
%\dorecurse{10}{\input zapf \par \input ward \par} \obeydepth
\startnestedboxedcolumns
\dorecurse{15}{\input zapf\par}
\stopnestedboxedcolumns
\par \input zapf \par \obeydepth
