[NTG-context] Vertical offset in framedtext has changed

[Christoph Reller via ntg-context]

Hi,

Somewhere between versions 2021-07-06 and 2021-07-30 the vertical
top-offset in framedtext has changed. Consider the MWE:

\starttext
\startframedtext
  Bla
\stopframedtext
\stoptext

Output 2021-07-06:
[image: FramedText-ConTeXt-2021-07-06.png]
Output 2021-07-30 (and later):
[image: FramedText-ConTeXt-2021-07-30.png]
Is this a regression?

[NTG-context] Disable hyphencollapsing for mono

[Christoph Reller]

Hi,

I would like to disable hyphen collapsing (automatic "--" to
endash conversion) document-wide for the currently selected mono font.

Consider:

\starttext
%{\nohyphencollapsing
  \mono{--}
%}
--
\stoptext

When uncommenting lines 2 and 4, the two hyphens in \mono{--} are not
collapsed. How can I configure never to collapse hyphens exclusively in
mono fonts?

Any help is appreciated.

Cheers,
Christoph

[NTG-context] \pdfbackendcurrentresources not expanded

[Christoph Reller]

Hi,

Consider the following MWE, which uses the tizk module:

\usemodule[tikz]
\usetikzlibrary[fadings]
\starttext
\starttikzpicture
  \fill [path fading=west,red] (-1,-1) rectangle (1,1);
\stoptikzpicture
\stoptext

When compiling with ConTeXt LMTX version 2021.06.18, the output PDF
contains "\pdfbackendcurrentresources" in the middle of a resource
dictionary. Apparently, this command does not get expanded but is written
literally to the file, which makes the PDF corrupt.

This command is used in the tikz module file pgfutil-context.def as:
  \def\pgf@sys@pdf@possible@resources{\pdfbackendcurrentresources}
As mentioned in a comment in back-pdf.mkxl, the command is implemented in
lua in lpdf-ini.lmt.

The command is also used in mlib-pps.mkxl and is documented in ConTeXts
interface. Can somebody tell why it is not expanded?

Any help is appreciated. Cheers,
Christoph

[NTG-context] Font glyph replacement regression

[Christoph Reller]

Hi,

In my documents I use the MyriadPro font of Adobe. Until recently, some
glyphs were automatically replaced (in a correct way) for this font. In
ConTeXt LMTX version 2021.09.18, the replacement stopped working:

1. En dash and em dash: "--" and "---" are not by default replaced any
more. Using the font feature "trep" brings back the replacement in this
case. See https://www.mail-archive.com/ntg-context@ntg.nl/msg98162.html

2. Apostrophe: "'" is not replaced by the proper apostrophe anymore.
Unfortunately, I don't know any font feature to bring back this replacement.

Any hints for this issue? (I can provide the MyriadPro font for debugging
purposes.)

Cheers,

Christoph

[NTG-context] Natural tables framecolor=white regression

[Christoph Reller]

Hi,

Consider the following MWE:

\starttext
\setupTABLE[
  rulethickness=5pt,
  framecolor=white, %red,
  background=color,
  backgroundcolor=gray,
  frame=off]
\setupTABLE[1][2][foregroundcolor=white, topframe=on]
\setupTABLE[r][2][topframe=on]
\bTABLE[setups=table:color]
  \bTR \bTD One   \eTD \bTD A \eTD \eTR
  \bTR \bTD \rotate[rotation=90]{Two} \eTD \bTD B \eTD \eTR
\eTABLE
\stoptext

Attached is the result for ConTeXt LMTX version 2021.04.09 (and earlier)
and for version 2021.06.18. In the latter case, the white frame is missing
in the first column between row 1 and 2. Changing the frame color to red,
makes the frame appear.

Could this be a bug or am I doing something wrong?

Thank you for looking into this. Cheers,

Finally I found the time to do some extended testing on this and it seems
that for my use-case the LMTX version 2021-06-09 behaves as I would expect:
Hyphens are now extracted as hyphens.

Thanks a lot for your implementation, Hans!

[NTG-context] Modify ToUnicode with Goodies

[Christoph Reller]

Hi,

On Windows, we have the consola font. Consider the MWE:

\starttext
\definedfont[name:consola*default at 12 pt]
-
\stoptext

The output PDF is correctly generated with recent versions of ConTeXt LMTX.
The hyphen is, however, mapped to a soft hyphen
 by means of the ToUnicode table which
contains:
beginbfchar
<015E> <00AD>
endbfchar

Consequently, when copying the text from the PDF and pasting in an editor
or a console, the soft hyphen is pasted.

I would like to change the ToUnicode information to an ordinary hyphen-minus
:
beginbfchar
<015E> <002D>
endbfchar

I have tried with a goodies file, and an updated MWE:

--- 8< --
return {
   name = "consola",
   version = "1.00",
   comment = "",
   author = "",
   copyright = "",
   remapping = {
  tounicode = true,
  unicodes = {
 hyphen = 0x002D,
  },
   },
}
--- 8< --
\definefontfeature[consola][mode=base, goodies=consola, unicoding=yes]
\starttypescript[mono][consolas]
  \definefontsynonym[ConsolasRegular][file:consola][features=consola]
\stoptypescript
\starttypescript[mono][consolas]
  \definefontsynonym[Mono][ConsolasRegular]
\stoptypescript
\definetypeface[Body][tt][mono][consolas][default]
\setupbodyfont[Body, ss, 10pt]

\starttext
\tt -
\stoptext
--- 8< --

Unfortunately, this has no effect.

Please tell me how to correctly update ToUnicode information with a goodies
file.

Re: [NTG-context] Markdown module in LMTX

[Christoph Reller]

Hi all,

In recent versions of ConTeXt LMTX the markdown module seems to work again.
I just copied the files m-markdown.mkiv and m-markdown.loa from a MKVI
version into the directory tex\texmf-modules\m-markdown of the LMTX version.

I don't believe that this is officially supported and I did no extensive
testing, but for my use case it works.

Cheers,
Christoph

For me this is good enough, because I define modes always in top-level

Thank you for this hint, Aditya. This would be a very nice solution indeed.
But it does not seem to work:

% macros=mkix
\definemode[A][yes]
\starttext
\startluacode
  if tex.modes['A'] then
context("A")
  end
\stopluacode

A

\stoptext

With ConTeXt LMTX 2021.03.17 the output of the above is a single "A". I
would expect two. What am I doing wrong?

[NTG-context] Error "double-free glue_spec"

[Christoph Reller]

Hi,

For one of my projects ConTeXt LMTX 2021.03.17 17:46 fails with:

error (nodes): attempt to double-free glue_spec node 145, ignored
mtx-context | fatal error: return code: 1

Unfortunately, when I try to minimize the project, the error vanishes. I
guess I have to send Hans the whole project, or are there other
possibilities?

Cheers,

Christoph

Thank you for hinting at the environment form. The problem with this is,
that it cannot be nested, and that there is no "else" form.
E.g:

\startmode[A]
... mode A
\startmode[B]
... mode A and mode B
\elsemode
... mode A and not mode B
\stopmode
\stopmode

I know that there is \start(not)mode and \start(not)allmodes, but there
seems to be no way to use a general boolean expression such as:

\startmodes[A and not B]
...
\stopmodes

Of course we can do this in lua:

if tex.modes["A"] and not tex.modes{"B"] then
...
end

Keep up your excellent work! Cheers,

Christoph

[NTG-context] Typing within doifmode leads to error

[Christoph Reller]

Hi,

Consider the following MWE:

\definetyping[T]
\definemode[mode][yes]
\starttext
\doifmode{mode}{%
  \startT
Bla
  \stopT}
\stoptext

Compilation with the currently latest ConTeXt LMTX (ver: 2021.03.17 17:46
LMTX  fmt: 2021.3.18) fails with:

tex error   > runaway error: end of file encountered
mtx-context | fatal error: return code: 1

Compilation is successful if I replace doifmode{mode}{...} by
\startmode[mode]...\stopmode.

Is there anything I'm missing? (This could be a bug.)

Okay, the MKIV version is a little bit dated: 2018.05.19_21.46.
Still: How can I get floats without captions within a
floatcombination environment?

[NTG-context] Table disappears in floatcombination

[Christoph Reller]

Hi,

Consider the following MWE:

\definefloat[combination][figure]
\setupcaptions[
  number=no, %<- comment and table appears
  align=flushright]
\starttext
\startplacecombination[title=Combination]
  \startfloatcombination
\startplacetable%[title=Table] %<- uncomment and table appears
  \bTABLE \bTR \bTD Cell \eTD \eTR \eTABLE
\stopplacetable
  \stopfloatcombination
\stopplacecombination
\stoptext

In the latest LMTX version of ConTeXt, the table is not shown. (In MKIV it
is present.) Either commenting line 3 or activating the table title in line
8 makes the table appear.

Also, once the captions appear, they don't align on the right side. When
changing the caption alignment to "align=flushleft", they align perfectly
on the left side.

Am I doing something wrong?

Cheers,

Christoph

Thank you for the implementation, Hans!

 A small issue: When omitting the referencetext, then the shown text is now
something like "248>desc:referencetext".

MWE:
\definedescription[desc]
\starttext
\startdesc[title=Long title, reference=foo]%, referencetext=Short title]
  \input jojomayer
\stopdesc
\about[foo]
\stoptext

For backward compatibility, it might be better to use the title as a
default for the reference test.

[NTG-context] \dodoubleemptywithset not working in LMTX

[Christoph Reller]

Hi,

The following MNWE uses \dodoubleemptywithset. In ConTeXt MKIV it works as
expected,  In ConTeXt LMTX an error results.

\starttext
\unexpanded\def\doMyDefs[#1][#2]{\getparameters[MD#1][#2]}
\def\MyDefs{\dodoubleemptywithset\doMyDefs}
\MyDefs[A,B][key=val,k=v]
\MyDefs[C]
\typeTEX{\MDAkey} is \MDAkey. \typeTEX{\MDBkey} is \MDBkey.
\typeTEX{\MDAk} is \MDAk. \typeTEX{\MDBk} is \MDBk.
\stoptext

Possibly, \dodoubleemptywithset is not used anymore in LMTX, in which case
it should be removed. Otherwise this could be a bug. Or maybe I use it
wrongly?

[NTG-context] Combinations not working as expected

Dear list,

In the latest version 2020.11.28 13:18 of ConTeXt LMTX, combinations don't

\stopcombination
\blank[big]
\startcombination[1*2]
  {first}{a}
  {second}{b}
\stopcombination
\stoptext

The output is

The layout argument [2*1] or [1*2] does not seem to have an effect and the
caption placement for "b" is strange.
Am I doing something wrong?

\stopbuffer
\xmlprocessbuffer{demo}{test}{}
\stoptext

My questions:
- Is there a good way to have a separate XML setup for each XML namespace?
- Alternatively, one has to do the distinction within the same XML setup.
In this case, how do we get the complete namespace? (In this example:
"NameSpaceA" and "NameSpaceO")

Thanks in advance for your help!

Correct me if I am wrong, but there does not seem to be a font file named
uzdr* in the distribution tree.

 Dear Hans,

Thank you for working on this. I have tried version 2020.09.20: Unicode
input works for the "Private Use Area" Unicodes reported in
\ShowCompleteFont. Such Unicodes are, however, not desirable. Moreover, in
MKIV, a Unicode U+2713 (Check Mark) in the input did produce the
ZapfDingbats check, e.g. as follows:

\definefontsynonym[ZapfDingbats][file:ZapfDingbats][features=dingbats]
\definefont[zapfdingbats][ZapfDingbats]
\starttext
{\zapfdingbats ✓}
\definedfont[name:ZapfDingbats]✓
\stoptext

I still get no check mark in the output PDF and a log message "char ✓
(U+02713) in font 'ZapfDingbats-4' with id 8: missing". Am I using the font
wrongly?
(This has not a high priority for me, because I have the unified access by
glyph index.)

Access by glyph index with \tochar{i:19} works well for both MKIV and LMTX.
Access by name with \tochar{n:a39} does not work in LMTX with log
message: char ✓ (U+02713) in font 'ZapfDingbats-4' with id 8: missing. Also
\ShowCompleteFont does not report any glyph names in LMTX.

[NTG-context] ZapfDingbats Unicode differences MKIV vs LMTX

[Christoph Reller]

Dear List,

I have the following MWE:

\definefontsynonym[ZapfDingbats][file:ZapfDingbats][features=dingbats]
\usemodule [fnt-10]
\starttext
(1) \getglyphdirect{ZapfDingbats}{61491}\crlf % MKIV log: char  (U+0F033)
in font 'ZapfDingbats-4' with id 8: missing
(2) \getglyphdirect{ZapfDingbats}{983059} % LMTX log: char  (U+F0013)
in font 'ZapfDingbats-4' with id 8: missing
\ShowCompleteFont{name:ZapfDingbats}{14pt}{1}
\stoptext

In MKIV, line (1) fails to output the requested glyph, while line (2)
produces a "check" (✓). In LMTX, line (2) fails and line (1) produces the
"check" (✓) . The output of "\ShowCompleteFont" reports differing Unicodes
for the same glyphs. Apparently the Unicodes for ZapfDingbats have changed.

I would like to have a "check" (✓) in the output for both MKIV and LMTX.
Options:
A) Is there a way to address the glyph in ZapfDingbats for both MKIV and
LMTX uniformly, e.g. by glyph index? (By glyph name does not seem to work:
MKIV reports glyph names, LMTX does not.)
B) Is there a conditional that I can build into the source to distinguish
between MKIV and LMTX?
C) Is there a font in the distribution for which I can have a
"check"-symbol in both MKIV and LMTX?

Any help is appreciated!
Cheers,

Christoph

[NTG-context] Access violation

[Christoph Reller]

Dear developers,

I am using ConTeXt LMTX version 2020.09.05 21:18 on Windows 46bit.

I have a large project for which I can reproduce an access violation:
mtx-context | fatal error: return code: -1073741819
Unfortunately, the error vanishes as soon as I alter any detail in the
project's source code.

The access violation happens always at the same location. I have produced a
log file for which I have enabled \tracingall just before the error
happens. I suspect that the error is triggered due to tagging information
written to the PDF (\setuptagging[state=start]), because disabling tagging
prevents the error. The log file (as a ZIP archive) is here
.
Does this help or do you really need a MWE?

Kind regards

[NTG-context] Input file name containing full stop "."

[Christoph Reller]

Dear list,

I am using ConTeXt LMTX Version 2020.09.05 21:18 with an input file named,
e.g., "test.test.tex". When compiling, ConTeXt generates files "test.log",
"test.tua", "test.pdf".

ConTeXt MKIV used to produce files "test.test.log", "test.test.tua",
"test.test.pdf".

Is there a way for ConTeXt LMTX to process input files that contain full
stops consistently? I am aware of the "--result=..." option, but what about
the "...tua", "...log" and synctex files? This is a serious problem when
running multiple compilations in parallel, e.g., on "test.a.tex" and
"test.b.tex", because both processes use the same "test.tua" file.

[NTG-context] MKIV - LMTX difference: stripping of leading white space in verbatim text

Dear List,

I am using ConTeXt LMTX 2018.05.19 21:46. Consider the following MWE:

\starttext
\startLUA
whatever
\stopLUA
\stoptext

In contrast to ConTeXt MKIV, the leading four spaces in front of "whatever"
are not removed when processing the verbatim text:

MKIV output:
whatever

LMTX output:
whatever

Is there a way to get the old MKIV behavior back?

When comparing the output with ConTeXt MKIV, then the image size is
extremely small. gimp reports the resolution of resolutionTest.png as
71.984 DPI. Is this a bug? (I cannot reproduce the shrinkage with

Also, I noticed that the "resolution" key when applied as:

  \externalfigure[resolutionTest.png][resolution=150]

has no effect. What is the meaning of this key?

I found that resetting the breakpoints within the typing command works:

\setbreakpoints[compound]
\definetype[typeLUA][option=LUA, command=\resetbreakpoints]
\starttext
\typeLUA{function(argument)}\par
If compound break points are enabled then this text line is broken after

Re: [NTG-context] follow up

[Christoph Reller]

My two cents:

I don't believe that it is the CIDSet. Both fun.pdf and fun1.pdf have no
CIDSet (which is good).
The (relevant) differences between the two PDFs are:
- Different ToUnicode
- Different embedded font stream
- Minor differences in the font descriptor
It could be the ToUnicode: If preview is not able to parse the last entry
in the ToUnicode table then it may also drop this glyph in its display,
although ToUnicode is only relevant for text extraction.
It could be the font stream: In the CFF font file there is a CharSet table
that maps character-IDs to glyph-IDs. If preview cannot read the last entry
in this table (or the last glyph, glyph nr. 10) then it might drop it.
By bet is on the ToUnicode, because, usually, if viewers fail to read a
font file then they drop the entire font file and not single glyphs.

Anyway, both PDFs seem to be valid. But I wonder if the differences in the
font descriptor are legitimate (especially StemV):
Object 9 <-> 7: Different entry Ascent integer value: 1127 <-> 806 in font
descriptor dictionary.
Object 9 <-> 7: Different entry Descent integer value: -280 <-> -194 in
font descriptor dictionary.
Object 9 <-> 7: Different entry StemV integer value: 91 <-> 0 in font
descriptor dictionary.

Cheers,
Christoph

[NTG-context] \reference not working with reference prefix and focus=standard

[Christoph Reller]

Hi,

Thank you, Hans, for supporting the focus=standard option in interactive PDFs.

I stumbled over the following problem:

\setupinteraction[state=start, focus=standard]
\starttext
\pushreferenceprefix{parent}
\reference[label]{Text}Bla
\page
\about[label]
\popreferenceprefix
\stoptext

The link's visual appearance is generated correctly and the PDF link
annotation correctly references a named destination "parent:label". In
the PDF's catalog, however, the only named destination has a name
"label", lacking the prefix.

Could you please consider fixing this issue?

Kind regards,

Christoph

[NTG-context] Using goto in lua

[Christoph Reller]

Hi,

As mentioned in cld-mkiv.pdf, the entire ConTeXt interface can be called
from lua: This is great!

Unfortunately the ConTeXt command \goto is a little problematic because
goto is a lua keyword. Therefore, the following leads to a lua error:

context.goto("text", { "label" })

I guess the only way to call goto from lua is

context(false, "\\goto{text}[label]")

Am I correct?

Cheers,

Christoph

Thank you for your hint, Hans. \dodoubleempty renders both arguments
optional and hence the command can be used without any argument, which
is not what I intended. Of course I can still test in the command's
definition whether at least one argument is given and generate an
error myself.

In i-context.pdf, many arguments are documented as being optional and
I assume that all the others are mandatory. A quick test has, however,
shown that when omitting mandatory arguments, either no error is
generated (e.g., nothing is setup or defined) or an obscure error
emerges other than "! Use of \ doesn't match its definition".

So I take it as a design decision that reporting missing mandatory
arguments as errors is not part of the interface implementation, and
that is a perfectly acceptable decision for me. It is just good to
know.

Thank you all for your highly valued feedback!

Cheers,

Christoph

Thank you Hraban for pointing me to the wiki. I was aware of this page

Thank you Hans for this information. My question is rather about error
handling. I want:

\MyCommand[A][B] % <- succeeds with #1->A, #2->B
\MyCommand[A] % <- succeeds with #1->A
\MyCommand % <- fails with "! Use of \MyCommand doesn't match its definition"

I just wanted to ask whether there is a standard way to achieve this
with \doempty. If not, then this is also okay.

[NTG-context] Defining command with optional and mandatory arguments

[Christoph Reller]

Hi,

What is the right way to define a command with both mandatory and
optional arguments, e.g:

\MyCommand[optional][mandatory]

Consider the following MWE:

\unexpanded\def\MyCommand[#1]{
  \dosingleempty{\doMyCommand[#1]}}
\def\doMyCommand[#1][#2]{
  \doifsomething{#1}{number 1: #1\par}
  \doifsomething{#2}{number 2: #2}\blank[big]}
\starttext
\MyCommand[A][B]
\MyCommand[A]
\stoptext

In last year's versions of ConTeXt the output was

number 1: A
number 2: B
number 1: A

In the latest version of ConTeXt the output is

number 1: A
number 2: B
number 2: A

Is this behavior intended? How can I make a definition whose behavior
does not change in new versions of ConTeXt?

Cheers,

Christoph

In my opinion, verapdf has one advantage a couple of disadvantages:

+ If everything works out as planned then verapdf may become one of
the most widely adopted validators, free of charge and open source

- verapdf is yet relatively new and hence inmature
- verapdf currently only validates against the PDF/A specifications
and not (really) against the PDF specifications. This is bad because
the latter are integral parts of the former.
- verapdf does not validate embedded streams such as images, font
files and color profiles.

In short: Only if you are sure that the input document is a valid PDF,
then verapdf can be used to test PDF/A conformance.

Christoph

Well, verapdf is only a validator and not a converter.

And, by the way, there is no reasonable way to convert from, say, PDF/A-2b
to PDF/A-2a without a rediculous amount of AI or manual input because the
tagging cannot be created out of the blue. It has to be there from the
document's birth. This is what makes this ConTeXt feature so precious.

Christoph

To us, tagged PDF is important. Specifically, for PDF/A with
compliance level a, tagging is mandatory. ConTeXt is the only (!)
TeX-based PDF creation suite that can produce correct and reliable
tagging.

Our company is producing (and weekly updating) 67 manuals and
technical documents from more than 900 ConTeXt source files for our
software products. The output PDFs are converted to PDF/A-2a, which is
only possible due to ConTeXt's tagging.

From what we hear of our customers, PDF/A level a and PDF/UA are
becoming increasingly important, be it because of archiving issues or
because of legislation requirements. So please, maintain this
invaluable feature!

Cheers, and thank you for all the effort.

Dear Lawrence,

(Sorry for changing to bottom posting style.)

This issue is not about a trade-off between print-ability and
inter-activeness. If I understand Hans' position correctly, then at
least part of his reasoning is the following (please correct me if I'm
wrong): It is easy to produce two versions of a document from one
common source, one version for print and one for the screen. The
former needs no interactive links and the latter should best be viewed
fullscreen, i.e., without scrolling, in which case focus=standard is
unnecessary. While I largely agree with this approach, many of the
ConTeXt users (including myself) are not in a position to decide how
their documents should be published. I believe that many of today's
PDF documents still are meant to be both, viewed on screen and
printed. And it's only for this scenario that focus=standard makes
sense.

Kind regards,

Christoph

Dear all,

This is a long standing feature request reported multiple times by
myself and others with MWEs in
https://www.mail-archive.com/ntg-context@ntg.nl/msg79620.html and
https://www.mail-archive.com/ntg-context@ntg.nl/msg79727.html.

\setupinteraction[state=start, focus=standard]
\starttext
\about[figure].
\page
\placefigure[][figure]{Figure}{\externalfigure[cow.pdf]}
\stoptext

Please, Hans, I kindly ask you to reconsider. I am aware of your
opinion and reasoning about this issue. But I believe that for many of
us users, today's PDFs need to be both, interactive *and* printable.

If there is any way I can help or motivate you, then please tell me ;-)

You may actually be better off with Acrobat X then with Acrobat DC
when it comes to testing, because Acrobat DC has an even stronger
tendency to ignore errors silently. :-)

This is only one of many cases for which ISO-32000 is the spec and the

A small detail: The ISO specification for PDF 2.0 also defines the
first page in /PrintPageRange to be page number 1 (not 0). :(

Maybe, if I find the time, I will add TeX and Lua to my module some time.

That should not be the case. Could it be, that the highlight-xml
module fails to load? Please check your log file for a "module not
found" entry. I have attached the result of my earlier sample.

My module does not come in standard context. You have to download it
from https://bitbucket.org/philexander/context-highlight. If general
interest is high enough I can ask  to
add it.

Kind regards,

Dear Pablo,

At least for XML you could use my module highlight-xml:

\usemodule[highlight-xml]
\definetype[xml][option=xml]
\starttext
\startTEXpage[offset=2em]
  \xml{attr="value"}\crlf
  \xml{This is text.}
  \startXML
This is text.
  \stopXML
\stopTEXpage
\stoptext

Note that even partial XML is highlighted correctly.

Cheers,

Christoph

Re: [NTG-context] TikZ modules are missing \startmodule

[Christoph Reller]

Hi Christian,

Thank you for your support. I think you should insert a line

\startmodule[]

after \unprotect in the following files

\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgf.tex
\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgfbim.tex
\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgfcor.tex
\tex\texmf-modules\tex\context\pgf\frontendlayer\t-tikz.tex
\tex\texmf-modules\tex\context\pgf\math\t-pgfmat.tex

\tex\texmf-modules\tex\context\pgf\utilities\t-pgfmod.tex
\tex\texmf-modules\tex\context\pgf\utilities\t-pgfrcs.tex

The  should be the file-name without the leading "t-" and
without the extension ".tex".
E.g: \startmodule[pgf]

Please anybody correct me if I am wrong or missing something.

Kind regards,
Christoph

[NTG-context] TikZ modules are missing \startmodule

[Christoph Reller]

Hi,

Since a module nesting check has been introduced in file-mod.mkvi, the TikZ
modules provoke "module wrapping error" messages in the log file. May I
kindly ask the maintainer of the TikZ modules to insert the missing
\startmodule command in the following files:

\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgf.tex
\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgfbim.tex
\tex\texmf-modules\tex\context\pgf\basiclayer\t-pgfcor.tex

Thank you for your answer Luigi!

(And sorry for my slow response - spam filter was doing crazy things.)

Your solution indeed makes the footnote appear at the right place. But the
layout is not the same as with \startitemize[columns]. Consider:

Text \footnote{Bla}
\startcolumns
\startitemize
\dorecurse{8}{\item Item}
\stopitemize
\stopcolumns

This results in 5 "Item"s in the left column and 3 "Item"s in the right
column. On the other hand

Text \footnote{Bla}
\startitemize[columns]
\dorecurse{8}{\item Item}
\stopitemize

results in 4 "Item"s in both columns, which IMHO is more correct.

Don't you agree that \startitmize[columns] is buggy with respect to
footnotes? Or is the [columns] parameter not supported anymore?

Christoph

[NTG-context] \startitemize[columns] and footnote

[Christoph Reller]

Hi,

Consider the following MWE:

\starttext
Text \footnote{Bla}
\startitemize[columns]
\item Item
\stopitemize
\stoptext

In the rendered output, the footnote is drawn on top of the item (see
attached output.png). I am afraid this looks like a bug. Please consider
fixing this or tell me how to make footnotes render in the footnote area.

[NTG-context] Tagging nested itemize with interaction

[Christoph Reller]

Dear Hans,

Consider the following MWE with nested multi-column itemize and item label:

\setuptagging[state=start]
\setupinteraction[state=start]
\starttext
\startitemize[n]
\item[label] First
  \startitemize[a, columns]
  \item Second
  \item Third
  \stopitemize
\stopitemize\crlf
Bla \in{Item}[label].
\stoptext

The above results in a PDF whose tag tree looks as follows:

‹document›
 |-‹itemgroup› itemize
 |  |-
 |  |  |-‹itemtag›
 |  |  |  '-"1."
 |  |  '-‹itemcontent›
 |  | |-"First"
 |  | '-‹itemgroup› itemize
 |  ||-‹item›
 |  ||  |-‹itemtag›
 |  ||  |  '-"a."
 |  ||  '-‹itemcontent›
 |  || '-"Second"
 |  |'-‹item›
 |  |   |-‹itemtag›
 |  |   |  '-"b."
 |  |   '-‹itemcontent›
 |  |  '-"Third"
 |  '-‹link›
 | '-"Item 1"
 |-"Bla"
 '-"."

In this tag tree, the ‹link› item is placed wrongly inside the topmost
‹itemgroup›. It sould be located between "Bla" and ".". This happens
only if:
1. An itemization with multiple columns is nested in an itemization
2. Interaction is enabled.

I think this is a bug. Please consider fixing it.

Kind regards,
Christoph

Dear List,

I have noticed that in normal combinations \setupcaption[location=...] is
not honored either. MWE:

\setupcaptions[location=top, number=no]
\starttext
\placefigure{Two Tables}{
  \startcombination
{\bTABLE\bTR\bTD First\eTD\eTR\eTABLE}{First}
{\bTABLE\bTR\bTD Second\eTD\eTR\eTABLE}{Second}
  \stopcombination}
\stoptext

The caption "Two Tables" is located above the combination. The captions
"First" and "Second" are, however, located below. How can I setup captions
such that "First" and "Second" are located also above? If this is not
supported then I would be glad to know.

By the way, I have noticed that \setupcaptions is missing from
i-context.pdf. Is this omission on purpose?

Kind regards,
Christoph

Hi Floris,

Thank you for asking. Consider the following MWE:

\setupbodyfont[cambria]
%\setupquotation[method=font]
\starttext
\quotation{A}\crlf
“A”
\stoptext

In the output rendering of the above (see attachment), the first line lacks
kerning between the double quotes and the letter A. This can be enabled by
saying \setupquotation[method=font]. At least that is what I know about
this option. Am I wrong? Is there a different option for enabling this?

Regards,
Christoph

In more recent versions, the above produces an error:

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

Is this a bug?

 Does anybody know a way to control the caption location in

Dear Taco,

"Change to temporary directory failed". Could you please be so kind and
check once more what could be wrong with the server.

[NTG-context] Module Update from GIT URL Fails

[Christoph Reller]

Dear Taco,

Moica has told me that you are the maintainer of modules.contextgarden.net.
Is this correct?

I don't seem to be able to update my ConTeXt module "high". I try to create
a new version by entering the URL of my git repository
(g...@bitbucket.org:philexander/context-highlight.git)
into the GIT URL field and clicking submit. But the website then tells me
"Change to temporary directory failed". What am I doing wrong?

By the way: My web browser tells me that the certificate of
https://modules.contextgarden.net has expired.

Thank you for your input, Hans!

I see that the captions "TABLE" and "FLOAT" are placed on top while the
captions "Two" and "Two" are placed on the bottom. Is there a way to setup
the locations of the captions of floats within a floatcombination? In this
particular example, the goal is, that the captions "Two" and "Two" are
placed on top of the respective tables.

Cheers,
Christoph

Hi,

I am unsure whether this mailing list is the correct one to ask this
question. So please excuse the noise.

I tried to send an email to modu...@contextgarden.net and got the below
reply. On https://modules.contextgarden.net/help.html, this email address
is mentioned as the primary contact point to the maintainer of the
modules.contextgarden.net website. Who can I contact if I have a problem
with this website?

[NTG-context] Caption location in floatcombination

[Christoph Reller]

Hi,

It seems to me that the location given to \setupcaptions is not honored
correctly in floatcombinations anymore. Consider the following MWE:

\setupcaptions[location=top, number=no]
\starttext
\placetable[][]{One}{
  \bTABLE \bTR \bTD First \eTD \eTR \eTABLE}
\placefloat[][]{}{
  \startfloatcombination
\placetable[][]{Two}{
  \bTABLE \bTR \bTD Second \eTD \eTR \eTABLE}
  \stopfloatcombination}
\stoptext

In earlier versions of ConTeXt, both captions "One" and "Two" of both
tables are rendered above the respective table. In the currently latest
version, the caption "Two" is rendered below the table. Is this a bug or do
I have to setup caption location separately for floatcombinations?

Any feedback is welcome.

Cheers,
Christoph

Re: [NTG-context] Hyphenation with dashes in natural table

Dear Pablo, Rik, and Thomas

Thank you so much for your quick help! This gives me much more insight into
the matter. And you provide various solutions with their pros and cons. For
the moment I will stick to Thomas' suggestion \setupbreakpoints[compound]
because I don't want to change the source files.

Many thanks,

[NTG-context] Hyphenation with dashes in natural table

[Christoph Reller]

Hi,

It seems that the hyphenation algorithm for long words with dashes when
typeset in a natural table has changed.

MWE:

\starttext
\bTABLE[width=5cm]
\bTR
\bTD super-cali-fragi-listic-expi-ali-docious \eTD
\bTD The longest word known to me that ever had an appearance in a musical.
\eTD
\eTR
\eTABLE
\stoptext

In earlier versions of ConTeXt, the super-cali... word is hyphenated after
"expi-" and no overfull box occurs. In the currently latest version the
word is hyphenated after "super-" and, since the rest of the word does not
fit the table cell, it overlaps text in the right hand cell.

Could this be a bug or do I have to setup hyphenation differently in
natural tables? Any feedback is welcome.

Cheers,
Christoph

Indeed, this is much better! Thank you!
I recommend to include this as a patch in ConTeXt.

However: Testing never stops ;-) I have the following MWE:

\definemathmatrix[pmatrix][left={\left(},right={\right)}]
\math{
  \startpmatrix
\NC A \NC B \NR
\NC C \NC D \NR
  \stoppmatrix}

This (including your suggested fix) results in the following structure tree:


|-
| '-
|   '-
| '-
|   '-
'-
  '-
|-
| |-
| | '-
| |   '-

| '-"B"
'-
  |-
  | '-
  |   '-
  | '-
  |   '-"C"
  '-

  '-
'-
  '-"D"

I think that the  should be located within the , shouldn't
it?

Thank you Hans for this fix!

There seems to be, however, still a minor issue with a more complete MWE:
\math{
  \startmatrix
\NC A \NC B \NR
\NC C \NC D \NR
  \stopmatrix}

The resulting structure tree is as follows:

'-
  '-

|   |-
|   | '-
|   |   '-
|   | '-
|   |   '-"A"

The elements marked with (*) are IMHO unnecessary. Do you agree?

This is clearly a bug. The resulting structure tree of the above MWE is as

Thank you Luigi,

This error message is gone now. Sorry for the confusion I have created by
not having reported a well defined way to produce this message.

Cheers, Christoph

[NTG-context] Log message "Unknown filter 'DCTDecode'"

[Christoph Reller]

Hi,

In recent versions of ConTeXt/luatex, I observe the following log entry:

Syntax Error (77727): Unknown filter 'DCTDecode'

This happens if the document includes JPEG images, e.g:

\starttext
\externalfigure[hacker.jpg]
\stoptext

The output PDF looks, however, fine. Does this message have any
significance?

Cheers,
Christoph

[NTG-context] \setupinteraction[focus=standard] not working

[Christoph Reller]

Dear List,

First of all: Thank you Hans and folks for supporting focus=standard
for many things. There are, however, some major places where
focus=standard does not work correctly yet. I pick out the simplest
and in my opinion most severe one: Floats.

\setupexternalfigures[location={local,global,default}]
\setupinteraction[state=start, focus=standard]
\starttext
\about[figure].
\page
\placefigure[][figure]{Figure}{\externalfigure[cow.pdf]}
\page
\input tufte
\stoptext

The link text on page 1 in the resulting PDF correctly displays
"Figure" and the overlayed PDF annotation has a seemingly correct
destination "(figure)". But, in the PDF catalog's "Names"-tree the
only named destination present has the name "(#1)". This destination
points to the correct location on the correct page, it is only the
name that should read "(figure)" instead of "(#1)".

Please consider fixing at least this issue (even if you are not very
fond of focus=standard ;-), as it will be of tremendous value for many
users. If I can be of any help, then please let me know.

Regards,

Christoph
