Re: [NTG-context] Is this a bug in header marking?

[Rik]

I have resolved the issue in a practical, but unsatisfactory, manner.

I have resorted to creating an interlude, a new heading derived from 
title, setting it for left pages with no displayed head:


   \definehead[ChapterEpigraph][title]
   \setuphead [ChapterEpigraph][
  page={yes,left},
  insidesection=\vfill,
  aftersection={\vfill\vfill},
  header=empty,
  placehead=no,
 ]

Thus, \startChapterEpigraph can safely be placed before each 
\startchapter (and between the last \stopchapter of a part and the start 
of the next part) when that last chapter ends on a recto). This clears 
the chapter marking in the headings of the new verso. When there is an 
epigraph to set, it is placed in the ChapterEpigraph section.


This is unsatisfactory because it implements an inaccurate semantic 
model of the document – the epigraphs belong to the following chapter, 
not the numberless, nameless interlude.


And there is almost certainly a bug lurking here. I had considered 
adding the marking of the next chapter to the interlude to better tie 
the interlude to the place it belongs. When I made ChapterEpigraph 
derivative of chapter:


   \definehead[ChapterEpigraph][chapter]
   \setuphead [ChapterEpigraph][
  page={yes,left},
  insidesection=\vfill,
  aftersection={\vfill\vfill},
  header=yes,
  number=no,
  placehead=no,
 ]

and provided a marking:

   \startChapterEpigraph[marking={Same as next chapter marking}]

The resulting page displayed the marking of the previous chapter, not 
the marking provided. This appears to be the same behavior as in the 
example below in my first note, although I can provide another working 
example using this apparatus if anyone wants it.


Can we please have a \setuphead or \setupheads option to clear markings 
at the end of the level, and not simply override them when the next 
equivalent level starts? (Although perhaps, based on the observed issue 
described just above, there is some other logic at work here.)

As a followup to my query on suppressing header marking, I have

The book places chapter openings on recto pages which follow a verso 
that may have an epigraph. When there is no epigraph, the blank verso 
is properly unmarked by a header, but when there is an epigraph, the 
header from the previous chapter appears on the page. How can I 
eliminate this orphan header?

Re: [NTG-context] Remove header after ToC

Thanks, that should work.  However, searching through setup-en.pdf, I
found the conditional `\doifelseoddpage {CMD} {CMD}', which is precisely
what I needed.  Enclosed below is an example which is formatted as I
wanted.

1. I use `header=empty' in \setuphead [chapter], for otherwise I get a
   header on the pages where a chapter begins.

2. I use \setupheadertexts twice, first before the beginning of the
   front matter, and then before the beginning of the body matter, with
   settings appropriate for the respective block.

3. I use `\marking [chapter] {Contents}' before \completecontent, for
   otherwise I get no chapter name in the header for the ToC.

4. I use `\doifelseoddpage {\page [empty]} {}' after \completecontent,
   to do what you had suggested.

Thanks again for the help.

Regards,
Raghu.

Read "odd" instead of "even" in the place marked .

Dear Tomas,

Thank you for your kind help.

The change you made works when the ToC ends on an odd page, as in this
case when it ends on page 1.  However, if the ToC ends on an even page,
say on page 2, the modification you have suggested produces an empty
page with no headers on page 3, and then an empty page with
headers "4 ... Chapter." on page 4; the first chapter starts on page 5.
Enclosed below is an example of such a file.

I don't want the empty pages 3 (without headers) and 4 (with headers),
and I want the first chapter to start on page 3, which is the first
right hand, i.e., odd numbered, page after the end of the ToC.

I think what is required is a command \foo which implements the
following pseudocode:

if the current page is even numbered ; then
  \page [empty]
else
  do nothing
endif

Then, I can use

\startfrontmatter
  \completecontent
  \foo
\stopfrontmatter

Regards,
Raghu.

[NTG-context] Quotation with method=font produces error

[Christoph Reller]

Hi,

In previous versions of ConTeXt the following MWE worked:

\setupquotation[method=font]
\starttext
\quotation{A}
\stoptext

In more recent versions, the above produces an error:

! Extra }, or forgotten \endgroup
l.3 \quotation{A}

Is this a bug?

Christoph

 Does anybody know a way to control the caption location in
