[NTG-context] Re: blank line and \placefigure
Here is a minimal example that better describes my problem.
It seems to depend on the size of the image. 30 mm and 40 mm width
works, 35 mm does not.
I have not tested height, although the image I want to use would be
portrait format.
\setuplayout[grid=yes]
\setupinterlinespace[line=15pt]
\starttext
\input{knuth}
\startlinecorrection
\placefigure[left, none]
[]{}\externalfigure[cow.pdf][width=40mm]
\input{knuth}

Did you try
\setupfloat[figure][spacebefore=,]
?
or "none" or "{disable,nowhite,back}"
You can set the space only for *all* floats, e.g.
\setupfloat[spacebefore=...,spaceafter=...]
and not for a single float type only.

Thanks a lot Pablo for your comments, I think my bad Englisch did not let me be clear.

Of course, since this is all new for me, I possibly go around and aroung to get a little thing done. In the introductions to ConTeXt I never found the command startmakeup, so i had to figure out a way to do it.

Hi Miguel,
I’m afraid it isn’t entirely clear whether you intend to ask something
or not.

Section blocks are intended for that.
Just a comment, if your cover (or title) page involves a one and only
single page, you may use makeups, such as in:
\starttext
\startmakeup[standard][pagestate=start]
\dorecurse{25}{\input knuth}
\stopmakeup
\stoptext
My sample explicitly displays that makeups are intended for a single page.
Since actual content for that makeup would fit in six pages without the
makeup, it looks weird inside it.

If you are showing your code to list members, fine.
Sorry, but if there is a question here, I’m afraid you need to be more
explicit asking your question.
Just some comments:
> %%
> %%% LOS BLOQUES %
> %%%
In a minimal sample, comments as the previous one don’t provide any clue
to understand your code or the issue you might be dealing with.
It is wiser to keep the sample to its minimal form.
> \startsectionblock[portada]
> \setuppagenumbering[location=]
> \input{03_portadaEval.tex}%this is my title page
It is better to provide actual content than a file name.
BTW, if its contents cannot be in more than a single page, the approach
suggested above might be easier.
> \startfrontmatter[]
Empty brackets are not required here.
> \start
> \setuplayout[re
> \setupinterlinespace[.8ex]
I would say that this is extremely small even for an "x" to fit in.
Again, just in case it might help,
Pablo

Section block force by default a page break which can produce unexpected

You can fix this by disabling the page break at the start/end of the

\setupsectionblock [bodypart] [page=]

[NTG-context] Unwanted blank page before page figures when using non-placed (hidden) heads

[NTG-context] Blank lines discarded when \typing
Note the presence of double-spaced blank lines in the following document
and in the attached source file:
\setuptyping[numbering=line]
\starttext
\startbuffer[javacode]
try {
final var num = stack.pop();
if( num != null ) {
stack.push( blah );
}
return true;
}
\stopbuffer
\type{\typebuffer}:
\typebuffer[javacode]
\type{\typing}:
\starttyping
try {
final var num = stack.pop();
if( num != null ) {
stack.push( blah );
}
return true;
}
\stoptyping
\type{\typefile}:
\typefile{t.java}
\stoptext
There appear to be two issues.
First, \typefile produces what I'd consider the "correct" result, where the
double-spaced lines appear on the page as a double-space. Both the
\typebuffer and \typing commands ignore double-spacing. The double-spacing
is also ignored by \xmldisplayverbatim. How would you configure to give
\typebuffer, \typing, and \xmldisplayverbatim to honour double-spaces the
same way as \typefile?
Second, of lesser importance, is that the blank lines aren't numbered. This
makes the line numbers inconsistent with respect to IDEs. How would you
label all blank lines as well?
Out of curiosity, does the second issue relate to the first?
Thank you!
try {
final var num = stack.pop();
if( num != null ) {
stack.push( blah );

[NTG-context] Blank line after \item: MkIV vs LMTX and how to properly get rid of it
Hello.
Consider the following small example:
8< --
\starttext
\startitemize[n]
\item \input tufte
\item \placefigure[right,none]{}{\externalfigure[cow]}%
\input tufte
\item \blank[overlay]%
\placefigure[right,none]{}{\externalfigure[cow]}%
\input tufte
\stopitemize
\startitemize[n,intext]
\item \input tufte
\item \placefigure[right,none]{}{\externalfigure[cow]}%
\input tufte
\item \blank[overlay]%
\placefigure[right,none]{}{\externalfigure[cow]}%
\input tufte
\stopitemize
\stoptext
8< --
I see a difference in MkIV and LMTX work:
- MkIV always put a blank line despite '\blank[overlay]' command;
- with \blank[overlay] and 'intext' option LMTX clutters item label (number in
this case).
Q1: is this the expected behavior for MkIV and LMTX? I found a recipe with
\blank[overlay] in the mailing list.
Q2: is it expected that LMTX will clutter item label when I use
\blank[overlay]? I suspect the answer is "yes" due to the option name.
Q3: how to prevent blank line insertion in such case: an item with text
framing a picture (on right side or on left side but the picture is below
the item label)?

Depending on what you want, you can try adding \testpage[n] (where n is a
number). This checks if the remainder of the page has enough space for n lines;
if not, then it issues a page-break.

[NTG-context] Progressively encouraging page/column breaks at \blank with penalties
Hi,
I'm trying to implement a section break marker in a grid layout. At a
section break, two lines of space should separate the subsequent segments
of text (just plain paragraphs, in this case), and a symbol (in the example
below, "X") should be set in the middle of these two lines. For my
purposes, the section break symbol should never occur at the top of a page
or column, and it is more desirable to have a page or column end with the
section break symbol than to have a single orphaned line follow the symbol
at the end of the page or column. Based on these constraints, I thought
that using the "samepage" and "preference" options for the first and second
line breaks would work nicely:
```
\define\SectionBreak{%
\blank[halfline, samepage]% non-breaking to ensure that no column
begins with the section break symbol
\startalignment[middle]%
{X}% section break symbol
\stopalignment%
\blank[halfline, preference]% this can (and, if possible, should) be
broken across a column
```
This does successfully prevent the placement of the symbol at the top of a
page/column, but it doesn't encourage the placement of the symbol at the
end of a page/column as often as I would like. I tried replacing the
"preference" option with options with better negative penalties, like
"penalty:-1000", "penalty:-2000", and even "penalty:-5000", but these
didn't make any difference. The option "penalty:-1" trivially works,
but it forces a page/column break at every section break marker, which is
far too extreme.
Is this normal behavior? I would have thought that progressively more
negative penalties would gradually encourage page/column breaks, but this
doesn't seem to happen. In the following MWE, the "preference" and
"penalty" options (apart from "penalty:-1") for the second line break
don't change the total page count or appearance of the final page at all
(which would be expected in a document of this size):
```
\setuplayout[
grid=yes %enable baseline grid
]
\setupinterlinespace[18bp] % text line spacing
%Define macro for section break:
\define\SectionBreak{%
\blank[halfline, samepage]%non-breaking to ensure that no column begins
with the section break symbol
\startalignment[middle]%
{X}% section break symbol
\stopalignment%
\blank[halfline]% a column break here is neither encouraged nor discouraged
% \blank[halfline, preference]% this should encourage a column break here,
but it doesn't seem to make a difference
% \blank[halfline, penalty:-1000]% still no difference
% \blank[halfline, penalty:-2000]% still no difference
% \blank[halfline, penalty:-5000]% still no difference
% \blank[halfline, penalty:-1]% this works, but it is too extreme!
}
%Set things up for fakewords:
\usemodule[visual]
\setupsystem[random=10]
\starttext
\dorecurse{400}{\fakewords{20}{100}\SectionBreak}
\stoptext
```
As always, any help is appreciated!

Re: [NTG-context] Suppressing headers and footers on blank pages before pagebreak at the end of a chapter.
rh...@t-online.de schrieb am 07.04.2021 um 20:20:
Hi list,
I typeset my first project with ConTeXt, a small booklet with some chapters,
frontmatter, no headers, but pagenumbers in the middle of the footers. I use
two environment files. The text is split into component TeX-files. All is
structured by a project and a product file.
Now I have run in some problems, I couldn’t solve with the garden and the
archives of this and stackexchange’s list. But I’m sure that it is almost too
simple for you experts. Let’s start with one.
As intended, a new chapter starts on a right/odd page. If the chapter before
ends on a right page, too, there should be a blank left/even page. But in my
case there is the pagenumber in the footer – which looks more horrible than an
orphan line.
A. Which setting in which setup or definition gives a command like:
suppress/skip/hide the header, footer and margin of last page of a chapter, if
the text area is empty.
B. More elaborate, a set of commands could
– distinguish between headers, footers, an margins and
– extend the commands on those pages at the end of the chapters
– that do not show any text within the last line of the text area, i. e.
the very last page of a chapter (even, but whith some text)
– or the second last page (odd, with some text, before a complete blank
even page).
A book design according to (A) is standard. I’m sure there is a solution in
ConTeXt.
(B) can be found often, at least in books from pre-computer times.
You have to change the argument of the page-setting for chapters.
\setuppagenumbering
[alternative=doublesided]
\setuphead

[NTG-context] Suppressing headers and footers on blank pages before pagebreak at the end of a chapter.
Hi list, I typeset my first project with ConTeXt, a small booklet with some chapters, frontmatter, no headers, but pagenumbers in the middle of the footers. I use two environment files. The text is split into component TeX-files. All is structured by a project and a product file. Now I have run in some problems, I couldn’t solve with the garden and the archives of this and stackexchange’s list. But I’m sure that it is almost too simple for you experts. Let’s start with one. As intended, a new chapter starts on a right/odd page. If the chapter before ends on a right page, too, there should be a blank left/even page. But in my case there is the pagenumber in the footer – which looks more horrible than an orphan line. A. Which setting in which setup or definition gives a command like: suppress/skip/hide the header, footer and margin of last page of a chapter, if the text area is empty. B. More elaborate, a set of commands could – distinguish between headers, footers, an margins and – extend the commands on those pages at the end of the chapters – that do not show any text within the last line of the text area, i. e. the very last page of a chapter (even, but whith some text) – or the second last page (odd, with some text, before a complete blank even page). A book design according to (A) is standard. I’m sure there is a solution in ConTeXt. (B) can be found often, at least in books from pre-computer times.

[NTG-context] blank pages bug [pagecolumns]
Hi there,
I noticed a bug when using pagecolumns. If there is a title on the right column,
a blank page gets added at the end of the document. For example
\starttext
\startpagecolumns[n=2]
\title{lorem}
\title{ipsum}
\stoppagecolumns
\stoptext
gives an additional blank page. If you remove the second title (ipsum) then not.
Best regards,
Johann

Re: [NTG-context] Asymmetrical Column layout leads to an extra blank page (Solved!)
Hello,
I managed to resolve the issue - which turns out bcos I had 2 back2back
columnset definitions. So instead, I combined them into 1 and the result
was ok.
*Before (leads to blank page or page with symmetrical columns):*
\definecolumnset[2col][n=2, distance=3.5mm, page=no]
\setupcolumnset[2col:1][width=.65\makeupwidth]
\setupcolumnset[2col:2][width=.35\makeupwidth]
\definecolumnset[3col][n=3, page=yes]
\setupcolumnset[3col:1][width=.25\makeupwidth]
\setupcolumnset[3col:2][width=.30\makeupwidth]
\setupcolumnset[3col:3][width=.45\makeupwidth]
\startcolumnset[2col]
...
\stopcolummnset
\startcolumnset[3col]
...
\stopcolummnset
*After (gets the desired result):*
\definecolumnset[summary][nleft=2, nright=3, distance=3.5mm, page=no]
\setupcolumnset[summary:1][width=.65\makeupwidth]
\setupcolumnset[summary:2][width=.35\makeupwidth]

[NTG-context] Asymmetrical Column layout leads to an extra blank page
Hello All,
I am new to this community and am really excited about the possibilities
with ConTeXt.
My question is related to the thread -
https://www.mail-archive.com/ntg-context@ntg.nl/msg92767.html (the
suggested solution did not work, unfortunately)
After trying out various options, I am faced with these 2 (sub-optimal)
choices -
1. Extra Blank page with Asymmetric Columns in the next page (with the
\subject{} uncommented)
2. No Blank page with Symmetric Columns (with the \subject{} commented)
3. page=yes / no - does not work (same outcome as above)
I am not sure the role of \section or \subject in this matter (seems to be
somehow interfering with asymmetrical columnset).
\usemodule[newcolumnsets]
...
% \subject{} \definecolumnset[soi1][n=3, distance=3mm, page=yes]
% \definecolumnset[currency][n=3, page=yes]
\setupcolumnset[soi1:1][width=.25\makeupwidth]
\setupcolumnset[soi1:2][width=.30\makeupwidth]
\setupcolumnset[soi1:3][width=.45\makeupwidth]
Any tips, help or pointers would be greatly appreciated. If not for
columnset, is there any other way to get this type of layout?

I tried using force but that caused a problem with aligning to the

I think I have seen \mbox used in this way in Latex, so was trying to
find a quick solution.

Hello list
I have been trying to find a solution to how to insert blank lines
before a chapter heading at the start of a page. In the following
example the \blank[4*big] is ignored. The solution I've found is to
add an empty box using \mbox{} before the \blank command.
I'm curious where the use of \mbox is documented.
Is this the right way to do it or is there a more elegant way that I
am missing?

You have to add the "force" keyword to \blank because TeX ignores by
default vertical space at the begin of a page.

[NTG-context] \blank space at the top of a page
Hello list
I have been trying to find a solution to how to insert blank lines
before a chapter heading at the start of a page. In the following
example the \blank[4*big] is ignored. The solution I've found is to
add an empty box using \mbox{} before the \blank command.
Is this the right way to do it or is there a more elegant way that I
am missing?
Many thanks
James

Re: [NTG-context] Blank page added after pagecolumns
I thought that the "yes" and "nop" suffixes were related to "page=yes" and
"page=no" for a few reasons. First, because I thought "nop" could be
shorthand for "no page." More importantly, however, I thought they might be
related because setting page=no in \definepagecolumns does not appear to
have any effect, and patching \page_col_stop_yes to do what
\page_col_stop_nop does had the desired effect. But as you have shown,
doing this causes problems with the transition back to a single-column
layout, so I suppose that the \page_col_stop_yes and \page_col_stop_nop
macros are meant to implement behavior dependent on the number of columns.
Your suggestion to add a column if the column at the end of the environment
is not the last one is elegant and works on different variations of the
MWE, including cases with more than two columns.

All right, I've found a tentative solution that appears to work in all
cases, but I'd like to know more about why the code I'm patching was
implemented in the first place, because I don't want to break anything
else. According to the code in page-pcl.mkiv, the \stoppagecolumns macro
has two implementations, \page_col_stop_yes and \page_col_stop_nop. The
choice of which implementation is used is determined by which of two
implementations of \startpagecolumns (\page_col_start_yes
and \page_col_start_nop) is used. That choice, in turn, is made in
the \page_col_start macro, in the following lines:
```
\c_page_col_n_of_columns\pagecolumnsparameter\c!n\relax
\ifnum\c_page_col_n_of_columns>\plusone
\expandafter\page_col_start_yes
\else
\expandafter\page_col_start_nop
\fi
```
so if the number of columns (i.e., the n option for the
pagecolumns environment) is more than one, the "yes" implementation of
the start and stop commands is used.
But this seems wrong. The naming convention for the two implementations
("yes" and "nop") suggests that they should be related the parameters
"page=yes" and "page=no" (hence, no page, which is what I think "nop"
abbreviates), but the choice of which implementation to use is
determined not by the page parameter, but by the n parameter. Is this an
error in the code, or am I just understanding this incorrectly? Is there
some reason why a layout with more than one column would need special
instructions to add a blank page after stopping the environment?
Why do you think "yes" and "nop" are related to the page-key?
In any event, I was able to solve the problem by patching the
\page_col_start_yes macro to invoke the \page_col_start_nop macro as
follows:
```
\unprotect
\def\page_col_stop_yes
{\page_col_stop_nop}
\protect
```
With this fix, the MWE I provided works regardless of which column the
text ends in. I'm content to consider the problem solved, but I would
certainly appreciate any feedback on my thoughts and questions about
page-pcl.mkiv.
You broke now now normal single columns text after the pagecolumns
environment. A better fix is to add a check for the \column command at
the end of the environment and add it only when we aren't in the last
column.
\unexpanded\def\page_col_stop_yes
{%\column % \page_otr_eject_page

Re: [NTG-context] Blank page added after pagecolumns
Okay, I think I'm getting close, but I'm not quite there yet. The
pagecolumns source code is found in page-pcl.mkiv (
source.contextgarden.net/tex/context/base/mkiv/page-pcl.mkiv), and in that
code, the \page_col_stop_yes macro seems to have something to do with the
issue:
```
\unexpanded\def\page_col_stop_yes
{\column % \page_otr_eject_page
\page
\endgroup
% \setupoutputroutine[\s!singlecolumn]%
\page_otr_command_set_vsize
\page_otr_command_set_hsize
\page
\endgroup}
```
If I redefine this macro in my MWE as follows, I can remove the extra page
that is added when the last page ends with text in the last column:
```
\unprotect
\def\page_col_stop_yes
{\column %\page_otr_eject_page
%\page
\endgroup
% \setupoutputroutine[\s!singlecolumn]%
\page_otr_command_set_vsize
\page_otr_command_set_hsize
%\page
\endgroup}
\protect
```
Commenting out the \page calls does the trick in this case, but now, if the
last page ends with its text in a column before the last one, then the last
page is not typeset at all, and a blank page takes its place.

Re: [NTG-context] Blank page added after pagecolumns
After continuing to look into this a bit, I noticed that a similar issue
involving the insertion of a blank page after a columnset environment has
been discussed on the mailing list in the thread "Blank page inserted when
text reaches column's end" (dated 08 Dec 2019). In that thread, a proposed
solution was to redefine the \page_grd_stop macro found in page-cst.mkiv as
follows:
```
\unprotect
\def\page_grd_stop{%
\endgraf % needed, else wrong vsize in one par case
\vfill % otherwise weird \placenotes[endnotes]
\page_grd_command_set_vsize % needed
\penalty\c_page_otr_eject_penalty
%\page_grd_command_flush_page
\page_otr_fill_and_eject_page
\page_grd_command_set_vsize % why here
\egroup
\page_otr_command_set_vsize
\page_otr_command_set_hsize
}
\protect
```
Unfortunately, this approach was found to have potential issues in that
thread, and it does not fix the problem with pagecolumns in my MWE. Are
pagecolumns commands aliased to pagegrid commands like columnset commands
are, or are they defined somewhere else? I checked page-col.mkiv, but it
seems to be too short to be the file that defines pagecolumns behavior.

Re: [NTG-context] Blank page added after pagecolumns
I recently found the pagecolumns manual (
http://www.pragma-ade.com/general/manuals/pagecolumns.pdf), and in several
of the examples (including those for side floats and footnotes), the
addition of a blank page after the end of the pagecolumns environment also
seems to occur. So when the manual says, "We always start at a new page and
end on a new one," does it mean that this is a feature of pagecolumns? And
if so, is there any way to disable it? I have no problem with a page break
after the end of the pagecolumns environment, but an empty page added after
the break seems unnecessary. I checked for a wiki page on the
\definepagecolumns command to get more information on its accepted inputs,
but there doesn't appear to be a page for this command.

[NTG-context] Blank page added after pagecolumns
I am typesetting a document using pagecolumns to ensure that my footnotes
are set ragged-bottom in columns. I have observed some unexpected behavior
whenever the last column on a page is left incomplete: a blank page is
added at the end of the document. A minimal working example follows:
```
\starttext
\startpagecolumns[n=2]
\dorecurse{3}{\par\input zapf}
\stoppagecolumns
\stoptext
```
I typeset this using ConTeXt version 2020.03.10, as released with TeXLive
2020. Notably, if \dorecurse{3} is changed to \dorecurse{2} or
\dorecurse{6} (so that the text ends in the first column of a page), then
there is no problem. I have tried to fix this by specifying page=no in the
\startpagecolumns arguments, but it did not change anything. Is there
something else I am missing?
Thank you,
Joey

To understand the differenecs between MkIV adn LMTX you should know how
\blank handles the arguments.
1. MkII
ConTeXt processes the argument list in TeX and checks first if the
argument is a valid name (e.g. big) which is then expanded, when the
argument isn't a valid name it is handled as a dimension which is added
to the skip value. Since everything happens in TeX length registers
(e.g. \lineheight) are allowed in the argument.
2. MkIV
ConTeXt passes the complete list with all arguments to Lua where a loop
iterates over all entries. The problem here is that Lua can't deal with
\lineheight because it expects the value of the register and you have to
pass the length as \the\lineheight which delivers the current value for
the line height.
3. LMTX
The same things as MkIV but there is a additional check on the TeX end
before the arguments are passed to Lua where ConTeXt checks if the
argument is a dimension. The reason why this is only done for LMTX is
that a new command (\ifchkdim) in the engine was needed for this and
many of these new helpers exist only here.
Be aware that this check works only when a length register is the
*first* argument in the list because every other case the check fails.

Re: [NTG-context] Blank page inserted when text reaches column's end
Thank you both. Neither approach removes the blank page with either
version 2019.06.11 or 2019.12.06 on Linux. Is there a specific version
of ConTeXt required? The code to generate the document resembles:
\setuppagenumbering[alternative=doublesided,page=no]
\installpagebreakhandler{last}{}
\setuplayout[grid=yes]
\starttext
\startcolumnset[n=2]
\input knuth \input lorem \input lorem \input knuth
\dorecurse{3}{No TV and no beer make Homer something something.}
\stopcolumnset
\stoptext
The second page remains, regardless of doublesided/singlesided or
pagebreakhandler.
Henri Menke pointed out that "page-cst.mkiv" contains an explicit line
break associated with stoppagegrid:
https://github.com/contextgarden/context-mirror/blob/f74c4055713ab52a11d12435eb04040ec6553129/tex/context/base/mkiv/page-cst.mkiv#L199-L201
Could this be grid itself be problematic?

With \setuppagenumbering[alternative=doublesided] you get a doublesided
document
with left and right pages. The default setting for chapters is to start
always on a right page
which can lead to empty left pages.
The normal layout are single sided document
(\setuppagenumbering[alternative=singlesided])
with right pages only which can't lead to empty pages unless you add an
extra check at the
begin of each chapter.
There is also a third mode which creates the same layout on each page
but you can
checl for left and right pages, this mode is enabled with
\setuppagenumber[alternative={singlesided,doublesided}].

Thanks a lot Wolfgang!
This was just the thing I was looking for. These setups seems to be the
golden bullet in ConTeXt but I often have difficulties to understand the
mechanism.
If you mean the setups-environment with setups you’re wrong because this
is only a alternative way to a command (e.g. \define\mycommand{...}).
The main point is that you finish the page before the section title and
check on the new page whether you’re on a odd or even numbered page.
When the test tells you that you’re on a even numbered page you know
there is a empty left page before the chapter which can be used to add
something special.
Below is a simplified example for the method.
\starttext
\dorecurse{10}{\samplefile{knuth}}
\page
\doifoddpageelse
{}
{\pushbackground[page]
\setupbackgrounds[page][background=color,backgroundcolor=red]
\page[empty]
\popbackground}
\dorecurse{10}{\samplefile{zapf}}
\stoptext
I'll try to wikify this later this week.
The push-pop-background pair is mentionend in x-setups-overview together
with some other push-pop-pairs or push single commands. Are they
documented somewhere?
Most of these push/pop commands are used for internal stuff (or
sometimes in styles) which means there is no documentation for them.
The purpose of them is to store the state of a command (e.g. the page
background) before you change its values, afterwards you can just revert
back to the previously saved state.
As these commands are no real environments they are listed as separate
commands but it’s possible I will change this.

I place an epigraph on verso page before a few chapters with the following:
\definehead[ChapterEpigraph][title]
\setuphead [ChapterEpigraph][
page={yes,left},
insidesection=\vfill,
aftersection={\vfill\vfill},
header=empty,

\resetbuffer [ChapterEpigraph]

[NTG-context] Spurious breaks in export when blank line ends paragraph
List,
My understanding of start/stop macros such as
\startparagraph...\stopparagraph has been that blank lines are allowed
between the block of text and the macros, as
\startparagraph
This is the text of the paragraph
\stopparagraph
However, in xml exports the blank line before \stopparagraph leads to
spurious break elements in some circumstances, as shown in the following:
\setupbackend [export=yes,xhtml=yes]
\starttext
\startsection[title=trailing blank line]
\startparagraph
Xxx xxx xx x xx xxx xx xx
xx. Xxx x, \inleft{z} x xx x
xx x xx xxx xx x, xxx xx
xxx xxx xxx xx xxx xx Xxxx , xxx
x xx x xx . Xxx x
xxx xxx xxx xx xx xxx,x
xx x xx, xxx xxx xxx x . Xxxx xxx
xx xx xxx xxx , xxx x xx
x x, xxx xxx x xxx xxx xx xx xx
\inleft{zz}. Xxxx x xx (x, xxx,
xx xxx xx).
\stopparagraph
\stopsection
\startsection[title=no blank line]
\startparagraph
Xxx xxx xx x xx xxx xx xx
xx. Xxx x, \inleft{z} x xx x
xx x xx xxx xx x, xxx xx
xxx xxx xxx xx xxx xx Xxxx , xxx
x xx x xx . Xxx x
xxx xxx xxx xx xx xxx,x
xx x xx, xxx xxx xxx x . Xxxx xxx
xx xx xxx xxx , xxx x xx
x x, xxx xxx x xxx xxx xx xx xx
\inleft{zz}. Xxxx x xx (x, xxx,
xx xxx xx).
\stopparagraph
\stopsection
\startsection[title=Another section]
\startparagraph
This is here to show the bottom of the previous section.
\stopparagraph
\stopsection
\stoptext
Note that the pdf output does not display the problem, but the pdf
output is not why one runs an export. The breaks disappear in shorter
paragraphs, and disappear when the margintext is not present, but appear
when margintext is present and the paragraph exceeds some length which I
have not worked to determine.
Is my understanding of the space rules incorrect, or is this a bug?
Since some breaks perhaps should be present, it is difficult to remove
these with CSS, or XSLT. One thing that might help is to add a class
identifier to breaks indicating what lead to their creation. Of course,
not generating these would be better still.

However, it fails when the buffer starts with an unescaped left square

is not a simple job to handle this. So, I will accept that I must either
append [] or get rid of the open layout for these cases.

Thank you, Wolfgang. That does it. Note that the % escaping the line
end is not needed ( although it might be needed outside a
\starttexdefinition environment) – the following works as well:
\starttexdefinition stopBufTest
\startnarrower[left,right]
\startparagraph
\dontleavehmode{\llap{? }}
\blank[overlay]
\inlinebuffer[TestBuffer]
\stopparagraph
\stopnarrower
\egroup
\stoptexdefinition
Alas, this is not yet a workable solution. It does not work with a
layout of grid=tolerant, which I am currently using (although it does
work with some other grid settings). For now I will just add empty [] to
the startBufTest invocations.
I really think, though, that a buffers.strip function would be the way

Thank you, Wolfgang. That does it. Note that the % escaping the line end
is not needed ( although it might be needed outside a
\starttexdefinition environment) – the following works as well:

Hi Rik,

Fair question.
I have a document with many (400+) block quotations. Each consists of
a text extract, which may be prose or poetry, and additional optional
components (alternate versions or transliterations, translations,
attribution). The optional components are distinguished
typographically – enlarged square brackets around alternate versions,
enlarged parentheses around translations, leading en-dash and hanging
indent for attributions. Each component is in a buffer. The structure
looks like:
\startBlockQuotation[label=abc,authors={...},precis={short
extract},translators={...},tprecis={{short extract},{short
extract}}...]
\startExtract[language=agr,align=yes,font=abc,tolerance=...,...]
text of extract
\stopExtract
\startTransliteration[language=en,align=yes,font=abc,...]
text of transliteration
\stopTransliteration
\startTranslation[...]
text of translation
\stopTranslation
\startAttribution[tolerance=,...]
attribution of quotation
\stopAttribution
\stopBlockQuotation
and the code to handle it generates author index entries, a quotation
precis index, and so on from the attributes of the envelope, and
typesets each component based on the provided settings or defaults,
placing the appropriate decorations around those components that call
for them. The components are nestable, so one extract may contain
another, and components can be used separately without the envelope
(\startBlockQuotation or \startEpigraph) as well.
(I have written it this way to ease the move to an XML-based format
for storing the quotations. I realize I am combining presentation
elements, like label, tolerance, and precis, and content elements,
like language, and some that may be either, like align and font, in
the attributes, but will deal with that later.)
I prefer to leave blank lines around blocks of text and around macro
commands, so:
\startparagraph
some text
\stopparagraph
but when this is done with, for example, \startAttribution, and no
optional arguments are provided, I run into the problem I have described.
Try to avoid blank lines at the begin/end of environments.
I realize that I can simply not include the blank line after
\startAttribution. I would prefer, however, to see consistent parallel
structures without having to distinguish them at the time it is
written. Perhaps I am being too picky, but that is what I am attempting.
At this point, the \setupparagraphintro hack handles my needs, so I
will proceed with that.

Hans,
That works for the over-simplified case here, but fails in practice.
For a \startnarrower[left] paragraph, the mark is still in the main
margin, not the 'margin' of the narrowed paragraph. Also, the
placement of the text in the margin is wrong and not easily controlled
as with \llap and \rlap. The code started out more like:
\define\Mark{\color[middlegray]{\hskip.6cm\itb¿\ }}
\setwidthof{\Mark}\to\MarkWidth
...
\starttexdefinition stopBufTest
\startluacode

So I am still looking for a way to do this. Meanwhile I am trying to
understand Aditya's examples.
Turns out another answer was hidden in Hans's reply. The following seems
to meet my needs, but it may complicate other use of
\setupparagraphintro (which I don't recall seeing before), so it may not
be a generic solution.
An empty string works fine instead of the llaped marking shown here.
This is a less dangerous hack than redefining \par, but still may fail
in more complex documents when \setupparagraphintro is used elsewhere.
\starttexdefinition stopBufTest
\startnarrower[left,right]
\startparagraph
\setupparagraphintro[first][\llap{\Mark}]
\inlinebuffer[TestBuffer] \ (first: \First, arg: \Arg)
\stopparagraph

\egroup

Thank you, Hans.
(For a non-hack generic solution that does not interfere with other use
of \setupparagraphintro, surely there must be an easy way to apply
string.strip to the buffer.)
