Hi Denis,

this is standard TeX behavior (not only related to XML):

  \starttext
  \externalfigure[test  two spaces.pdf]
  \externalfigure[test  not two spaces.pdf]
  \stoptext

I don‘t know whether this is intended or not.

That being said, more than one consecutive space in a file name (I would
say it) is rather an exception than the rule.

Fixing this may cause more trouble that it might seem at first.

Best,

Pablo

[NTG-context] escaping \ in Lua

[Pablo Rodriguez]

Dear list,

I have the following source:

  \setupinteraction[state=start, display=new]
  \enabledirectives[references.border=darkgreen]
  \starttext
  \startTEXpage[offset=1dk]
  \attachment[method=hidden, file=a(b).pdf]
  \stopTEXpage
  \stoptext

The name in EmbeddedFiles is "a\(b\).pdf".

Sorry for the obscure question, but how can I access this with
"\goto{link to external}[a(b).pdf]"?

I guess there may be some Lua magic, but I cannot write a proper
":gsub("%(", "%\%("))".

Many thanks for your help,

Pablo

Just in case it might be relevant, I was on W10.

I would say that a similar command was right for me.

But using Textadept 11.4 and invoking compilation from the editor
triggered the error in my case.

BTW, try "cd \\localhost\c$\data\develop\tmp" in the command prompt.

It was impossible for me on W10.

This is the real problem: UNC paths and the command prompt (CMD.EXE).

UNC paths are a Windows way to access remote units (let’s say it so).

They are similar to: "\\remote-server\directory\subdirectory\file.tex".

CMD is required by ConTeXt to run, but CMD doesn’t understand UNC paths,
so it switches the directory to the %SYSTEMROOT% (usually, C:\Windows).

This directory shouldn’t be writable (without admin rights).

So the file cannot be found, since the directory is not the one that
contains the source.

Using Explorer, it is possible to give a path such as
"\\localhost\c$\Users\USERNAME\whatever\file.txt" and open it with your
favourite editor, but it will be impossible to compile.

UNC paths in common used are mapped as local units, such as (explained
in https://ss64.com/nt/net-use.html#e):

  net use X: "\\remote-server\directory\"

That way compiling x:\subdirectory\file.tex would be no problem.

Hraban was right: there might be no %SYSTEMROOT%\blackrule1.tex.

Just in case it might help to understand was what wrong,

Hi Jeroen,

this might do the work (LMTX only):

  [\pagenumber{} of \the\numexpr{\totalnumberofpages - 1}]

For MkIV, you would need:

  [\pagenumber{} of \the\numexpr\totalnumberofpages - 1\relax]

Many thanks for your reply, Hraban.

I’m afraid that \in{attachment}[foobar] doesn‘t generate a link in your

Or do you get a link border from the following source?

[NTG-context] (feature proposal) link to attachments: /GoToE

[Pablo Rodriguez]

Hi Hans,

having attachments in PDF is very useful, but the vast majority of
people don’t know how to handle them (even with the attachment pane
displayed when Acrobat opens the document, or with file annotation).

It would be really useful to have a link with destination that it would
open the embedded document (when clicked).

Since in its basic functionality, this is very similar to links to
external documents (GoToR), I wonder whether it would be possible to
implement links to embedded documents (GoToE,
https://opensource.adobe.com/dc-acrobat-sdk-docs/pdfstandards/PDF32000_2008.pdf#G11.2048909).

At least to begin with, only links to embedded children documents would
be required.

If this GoToR is generated by ConTeXt from
"\goto{whatever}[destination-doc::page(15)]":

  17 0 obj
  <<
/D [ 14 /Fit ]
/F (destination-doc.pdf)
/NewWindow true
/S /GoToR
  >>
  endobj

A GoToE destination for "\attachment[file=destination-doc.pdf,
method=hidden]" would read:

  1 0 obj
   <<
/S /GoToE
/D [ 14 /Fit ]
/NewWindow true
/T << /R /C
  /N (destination-doc.pdf) >>
   >>
  endobj

With EmbeddedFiles, the F entry from GoToR is a target dictionary (T
key) in GoToE.

The T dictionary contains the relation (R key) to the destination file
(only C, child, needed) and the name (N) from EmbeddedFiles/Names for
the attachment.

This is the most basic implementation that allows to link to an
attachment.

What the spec describes as “a complete facility for linking between a
file in a hierarchy of nested embedded files and another file in the
same or different hierarchy” is probably unnecesarily complex (even to
use).

With file annotations, instead of the name from EmbeddedFiles/Names in
the target dictionary, it requires the keys P and A (as numbers or
strings).

  P gives the page number which contains the file annotation:
  zero-based as number, or named destination as string.

  A gives the annotation: zero-based index of the annotation in the
  Annots array, or NM entry value from the annotation object.

As for the interface, it would be great that GoToR links could be
converted automatically in "\goto{some text}[file::page(number)]" for
attached files.

This basic implementation of GoToE links would be extremely helpful to
access embedded documents (believe it or not, this is something I
explain almost every week at work).

I would be happy to provide the code to implement this, but I’m
afraid this is way beyond my knowledge.

Many thanks for your help,

Pablo

Many thanks for your reply, Wolfgang.

As always, many thanks for your valuable help.

Somehow I copied the assymptopically equal to character (0x2243) to
typeset I cannot remember what, and I also placed it there (instead of
the standard equals char [0x003D]).

Sorry, I‘m afraid I wasn‘t able to spot the difference (at a relative
small font size).

[NTG-context] slanted font feature: LMTX vs. MkIV

[Pablo Rodriguez]

Dear list,

I have the following sample (using current latest from 2023.08.27 13:48):

  \setupinteractionscreen[option=max]
  \definefontfamily[maf][rm][DejaVu Sans]
[sl={style:tf, features:{default,slanted}}]
  \setupbodyfont[maf, 8pt]
  \setupfittingpage[offset=1ex]
  \starttext
  \startTEXpage
  a {\em b}
  \stopTEXpage
  \startTEXpage[foregroundstyle={\setupbodyfont[100pt]}]
  a {\em b}
  \stopTEXpage
  \stoptext

Using LMTX higher font size gives less slanted text (or not at all).

Using MkIV text is slanted fine, independent from font size.

Could anyone confirm the issue?

This might be the result from the mess generated after three updates today.

Compare files lists from:

https://modules.contextgarden.net/cgi-bin/module.cgi/action=view/id=128
https://modules.contextgarden.net/cgi-bin/module.cgi/action=view/id=143

Many thanks for your work reviewing the modules, Hraban.

I was forced to avoid a git URL, since it provided .tar.gz compression
(instead of .zip compression, required by the new installer).

I have just updated both modules and they are TDS compilant again (or so
I guess).

But the issue I reported is still there
(https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/thread/C6RDJ5EYGOUQPOJGKOPRGDVPZOKDBIYE/#C6RDJ5EYGOUQPOJGKOPRGDVPZOKDBIYE):
download URL is .tar.gz.

Since Hans doesn‘t want to start mixing compression formats, would it be
possible that the git checkout selects .zip instead of .tar.gz?

Sorry, but the git URL seems to be the only way to get directories that
comply with TDS.

This would be the only way to get the modules script work with those
modes (or .tar.gz is also accepted as compression format for the modules
script).

Hi Idris,

This is already defined in lines 96-99 of font-pre.mkxl:

And also in lines 77-82 of font-pre.mkiv:

Just in case it helps, grep is a useful tool when applied to

Many thanks for adding that to the lowlevel manual.

Just in case this might help anyone, I always see what is new in latest

I always forget how to run modules, so compiling this also works:

  \stopTEXpage

So 1fw is equal to 2fo + 1lw, isn’t it? (I mean, frame width is left and

Hi Xavier,

as someone already mentioned it, the way to check would be:

  mtxrun --scripts check your-document.tex

But this doesn‘t parse \input, so you need to create a loop.

In Unix, it would read something like:

  for i in *.conTeXt; do mtxrun --scripts check $i; done

Windows might require something similar to (inspired by
https://ss64.com/nt/for.html):

  for %%I (*.context) do mtxrun --scripts check %%I

It might report the cause this way.

When ConTeXt quits unexpectedly ("mtx-context | fatal error: return
code: 1" is a error message from the console), it might be a started
command not closed, such as in:

  \starttext
\startitemize
  \item a

Dear Marcus Vinicius,

in PDF (the format itself), ActualText is a way of providing a text
replacement for the displayed element.

If you use ActualText, the string you search is the text replacement you
provide. That way, you could find literally “whatever you want” (being
"filia" its ActualText).

Hans provides this jewel in back-imp-pdf.mkxl and back-pdf.mkiv (adapter
for your needs):

  \starttext
  text \pdfbackendactualtext{whatever you want}{filia} text
  \stoptext

That being said, I think this is the wrong approach to your issue.

Firefox also disables diacritics by default (at least for me, this is
not a minor issue).

In any case, the PDF viewer used to search must have ActualText implemented.

I hope it helps,

Pablo

Hi Jairo,

Gerion, I was wrong, since I forgot enabling interaction in the main PDF
document to generate the targets (or named destinations).

  \setupinteraction[state=start, focus=standard]
  \starttext
  \dorecurse{15}
{\chapter[chap\recurselevel]{Chapter}}
  \stoptext

The first line was missing yesterday.

After that (and with the ouput from the second sample from my previous
message
[https://mailman.ntg.nl/archives/list/ntg-context@ntg.nl/message/IEEGSAL636X32C3WWMO2KWKXMTIARRGZ/]),
Xpdf/Evince/Okular solve remote links fine.

MuPDF-GL cannot solve the file (even when full path is provided) and
PDF.js doesn’t even seem to care there might be a link.

I’m totally ignorant about what Acrobat and Edge/Chrome might do.

I hope this helps,

Sorry, Gerion, my reply yesterday was rushed (no skin condition).

The solution is already there (in the test files).

You have the file with the reference (save it as main.tex):

  \starttext
  \dorecurse{15}
{\chapter[chap\recurselevel]{Chapter}}
  \stoptext

You have the file that reads the references from main.tuc and generates
the inter-document links:

  \setupinteraction[state=start]
  \starttext
  Links to each chapter using \type{main.tuc}:

  \startitemize[n, packed]
  \dorecurse{15}
{\item Reference to \in[main::chap\recurselevel].}
  \stopitemize
  \stoptext

The real issue is that I couldn’t make it work with any PDF viewer I
have on Linux.

Either the viewer doesn’t detect the link (such as PDF.js), or it cannot
solve the target file (such as MuPDF and MuPDF-GL), or it cannot reach
destinations (such as Xpdf, Evince/Okular or SumatraPDF).

I take for granted that Acrobat will deal fine with this, since
destinations in links (GoToR) seem to be fine.

Of course, to confirm this, it should be tested with Acrobat.

Just in case it helps,

Hi Gerion,

now I realize that my explanation was unnecesarily technical or not
focused on your needs.

My point was that if PDF as such doesn’t offer the capability, there is
no way to include it in ConTeXt (with PDF documents as output files).

I’m in a hurry, excuse my rash reply.

As far as I know (although I never used them), you can use \in with
references to other documents (I guess this is why you need the .tuc
file of the other document [to resolve the reference]).

In that case, you will have the reference number solved in your
document. As far as I know, there is no link for that.

Importing the document (with \externalfigure) has issues to preserve
internal links.

I hope it helps,

Hi Gerion,

not sure I’m getting your point right.

As such, one of the features of PDF are named destinations, such as in:

  https://www.pragma-ade.com/general/manuals/luametatex.pdf#%2381

I consider them as identifiers:

  https://wiki.contextgarden.net/Installation#Unix

If that could be what you might need, here is a sample.

First you have the destination file:

  \setupinteraction[state=start,
focus=standard,
prefix=n_,]
  \starttext
  \dorecurse{50}
{a\footnote{b} }
  \startluacode
  luatex.wrapup(
function()
  os.rename(tex.jobname .. ".pdf", "ba.pdf")
end
  )
  \stopluacode
  \stoptext

Then you have calling file (with file:///):

  \setupinteraction[state=start,
focus=standard]
  \def\MyURL#1{\goto{\tt#1}[url(#1)]}
  \starttext
  Link to other document: \MyURL{file:///path/ba.pdf\letterhash n_73}

  Link to the web:
 \MyURL{https://www.pragma-ade.com/general/manuals/luametatex.pdf#%2381}
  \stoptext

file:/// requires an absolute path. It might be handled right or not,
depending on your PDF viewer.

On Linux, Evince cannot open a file with named destination specified as
doc.pdf#destination (or doc.pdf#nameddest=destination). But it
understands file:///.

MuPDF-GL seems also not to handle named destinations, but it understands
file:/// too.

PDF.js (the default PDF viewer that comes with Firefox) handles named
destinations, but doesn‘t seem to understand file:/// as a link.

> Background of my question: I normally do graphics in a separate PDFs.
> Some graphics consists of source code together with a graphical

I think it may be possible, but I don’t know how to generate named
destinations for source code lines.

Just in case it may help,

To solve this issues (since I use my private directory for fonts), I

Before that, I had the symlink inside the LMTX distribution.

Hi Taco,

some messages include a "Reply-to" field. But other ones add in the
"From" field with the structure "Name Surname via ntg-context
" (original sender address is included in "CC" field).

The second pattern seemed to be the standard before the new HyperKitty

I’m experiencing the delay too, Michael.

BTW, it is really a pity that the new interface doesn’t consider all

[NTG-context] digitally sign fields with MuPDF-GL

[Pablo Rodriguez]

Dear list,

having the following sample code:

  \setuppapersize[A4, landscape]
  \setuplayout[page]
  \setupinteraction[state=start]
  \starttext
  \setupfield[sl][horizontal]
[frame=off, width=\textwidth, height=\textheight]
  \definefield[x][signature][sl]
  \field[x]

I also attach a sample certificate with password ABCabc.

The binaries for Windows provided by Artifex do not provide SSL support.
I’m on Linux myself, and something like MSYS2 provides binaries with
support for Linux (https://packages.msys2.org/base/mingw-w64-mupdf). I
wonder whether Homebrew provides mupdf-gl (I cannot say from
https://formulae.brew.sh/formula/mupdf).

If I try to sign the output PDF with the previous password, using
mupdf-gl or "mutool sign" (version 1.2.2), the signature annotation is
only viewed by MuPDF, MuPDF-GL and SumatraPDF.

On Linux, neither Evince or xpdf can display the signature annotation.

On Windows, Acrobat Reader DC doesn’t display the signature annotation,
nor it shows any info about the document being signed (BTW, I used
another certificate for this).

If I open the unsigned document with Acrobat Reader DC and save it, then
mupdf-gl can sign the saved document that Acrobat can handle (both
annotation and signature info) and Evince and xpdf can display the
signature.

I guess what might be causing this issue and I’m investigating it.

But it would really help, if someone can confirm the issue with MuPDF-GL
(or "mutool sign") and Acrobat (Reader or not).

Many thanks for your help,

Pablo

[NTG-context] Fwd: [veraPDF-users] Development Preview: PDF file checker based on the Arlington PDF Model

[Pablo Rodriguez via ntg-context]

Dear list,

it is still early development, but this tool might be extremely useful
to check PDF documents.

Direct link to downloads (version 1.25 doesn’t seem to be available):

  https://software.verapdf.org/develop/arlington/1.23

Just in case it might help,

Pablo

 Forwarded Message 
Subject: [veraPDF-users] Development Preview: PDF file checker based on
the Arlington PDF Model
Date:   Wed, 21 Jun 2023 12:35:12 +0100
  Dear all, 

On the 30th anniversary of PDF technology, we're excited to announce the
availability of the first development preview of a new veraPDF-powered
application. Building on the great work done by the PDF Association
supported by the Defence Advanced Research Projects Agency (DARPA),
veraPDF has developed an open-source PDF checker based on the Arlington
PDF Model. This application is separate from the veraPDF PDF/A and
PDF/UA validator but comprises a very familiar package of GUI and
command-line applications.

*The Arlington PDF Model is an invaluable resource for anyone developing
or testing PDF tools. *Read more about the development here.

 

The veraPDF development team have utilised  Arlington in a way that's
compatible with the veraPDF architecture. The Arlington PDF Model-based
checker can now analyse PDF files against the full PDF 2.0
specification, including errata, by downloading the Java-based installer
(Win, MacOS, Linux, requires Java 8+ JRE installed) at veraPDF Software
Downloads . 

Best wishes,

Helena

Hi Mikael,

I mentioned this in a message from 04/30/23, 15:47 with subject:

But no luck yet. Most recent message there seems to be
https://mailman.ntg.nl/pipermail/ntg-context/2023/date.html#108157.

Taco asked to report him personally or to a maling list
(https://mailman.ntg.nl/pipermail/ntg-context/2023/108140.html).

I sent a message to the mailing list (two weeks after having sent a
private message to Taco), but I received an automated reply (in Dutch)
to cancel the message being sent mentioning the fact that I’m not
subscribed to that list.

I hope the message now reaches Taco.

Best,

Pablo

[NTG-context] hyperlinks not working with current latest

[Pablo Rodriguez via ntg-context]

Dear list,

in the following sample, hyperlinks for footnotest don’t work with
current latest (2023.05.28 18:57) with current LMTX (20230528):

  \setupinteraction
[state=start,
 focus=standard]
  \starttext
  \completecontent
  \dorecurse{5}
{a\footnote{}}
  \stoptext

LuaTeX generates fine hyperlinks for footnotes.

My guess is that the issue is in the LuaMetaTeX binary.

Could anyone confirm this issue?

Many thanks for your help,

[NTG-context] new module installer and .tar.gz compression

[Pablo Rodriguez via ntg-context]

Hans,

many thanks for the new script to install modules in LMTX.

I forced a new release of handlecsv
(https://modules.contextgarden.net/cgi-bin/module.cgi/action=view/id=86).

I provide the contents with a git address, so I cannot choose which kind
of compression the code will have.

Since imports from git use .tar.gz, these modules cannot be installed
with the script (which seems to expect .zip compression exclusively).

Sorry, but I don’t know how to force git urls to be added as zip
packages in https://modules.contextgarden.net.

Many thanks for your help,

Pablo

I’m afraid I had to update the binaries manually.

After that, everything was fine.

Many thanks for your fast reply, Bruce.

For some strange reason, binaries weren’t updated to latest ones.

Copying them from a brand-new install fixes the issue.

I wonder whether other Linux64 users experienced this.

[NTG-context] no recent message listed in the web interface

[Pablo Rodriguez via ntg-context]

Dear list,

I‘m afraid that
https://mailman.ntg.nl/pipermail/ntg-context/2023/108157.html is the
most recent message displayed for 2023 in the web interface
(https://mailman.ntg.nl/pipermail/ntg-context/2023/date.html#108157).

Although the list has been distributing messages to subscribers and I
received them, I guess that the server software update might have
something to do with this.

Just for the record, I contacted Taco privately two weeks ago. No reply,
but I understand that obviously he is busy with other things.

Before sending him another message on the issue, I would like to ask
whether anyone could confirm that recent messages (from this week)
aren’nt being listed at
https://mailman.ntg.nl/pipermail/ntg-context/2023/date.html.

[NTG-context] cannot generate format file with current latest

[Pablo Rodriguez via ntg-context]

Dear list,

I have just updated to current latest (2023.04.27 17:04).

I always delete cache with "mtxrun --generate" after an update.

When I try to create the format file with "context --make --all", I get
the following error message:

lua error   > lua error on line 645 in file context.mkxl:

token call, execute: ...ext/base/mkxl/cldf-pos.lmt:18: attempt to index
a nil value (global 'posit') stack traceback:

...ext/base/mkxl/luat-cod.lmt:82: in function 'lua.registercode'

A number should have been here; I inserted '0'. (If you can't figure out
why I needed to see a number, look up 'weird error' in the index to The
TeXbook.)

Could anyone confirm the issue?

Hi Thomas,

I don’t know what check does (maybe just check?), but the standard
behaviour with \definefallbackfamily is only to fall back when the
character is missing from the main font.

To force all characters from the range in the fallback font, "force=yes"
is required.

Here you have a minimal sample (which doesn‘t use "preset=range:greek"),
adding "force=yes" gets all Greek glyphs from GFS Heraklit:

  \definefallbackfamily [presentation] [serif] [GFSHeraklit]
  [range={greekandcoptic, greekextended}]
  \definefontfamily [presentation] [serif] [TeXGyrePagella]
  \setupbodyfont [presentation,12pt]

  \starttext
  Pπμᾷσδ
  \stoptext

Just in case it might help,

But LM fonts don‘t have the OT feature smcp:

  \setuppapersize[A8]
  \starttext
  \doloopoverlist{lm, pagella, termes, heros}

Sorry, Luigi, I meant
http://mailman.ntg.nl/pipermail/ntg-context/attachments/20230401/1f8c6cc9/attachment-0001.pdf.

According to type-imp-concrete.mkiv, text has the feature boldened-10
applied to it.

Even with a variable font (which might not be the case in the link
above), extending the font fakes the bold, such as in:

  \definefontfamily
[mainface]
[rm]
[Source Sans 3 VF]
[features={default, boldened-10}]

  \setupbodyfont[mainface]

  \starttext
  \input zapf
  \stoptext

Evince displays it poorly and this is what happens in the link above.

Hi Luigi,

according to type-imp-concrete.mkiv, Concrete-Math.otf seems to be only
used for the math font.

Well, evince displays it wrong (this is an already known issue with fake

Re: [NTG-context] Absolute positioning of \startcombination... \stopcombination

Hi Keith,

I think the following sample might achieve what you want:

  \showframe
  \setupexternalfigures[location={default}]
  \setuplayout
[backspace=2.5cm,
topspace=1cm,
height=28cm,
width=17cm,
header=0cm,
footer=0.75cm,
]
  \definelayer[test3]
  %[x=.5\paperwidth, y=.5\paperheight]
  [x=.5\textwidth, y=.5\textheight]
  %\setupbackgrounds[page]
  \setupbackgrounds[text]
  [background=test3]
  \starttext
  \setlayer[test3][location={middle}]
 \framed[offset=overlay]{{\startcombination[nx=3,ny=1,distance=15mm]
{\externalfigure[cow][width=15mm]}{}
\rotate[rotation=90]{\externalfigure[cow][width=15mm]}{}
{\externalfigure[cow][width=15mm]}{}
 \stopcombination}}
  \null
  \stoptext

BTW, A4 portrait is the default page size.

\setupbackgrounds is the standard way to place layers.

Page and text centering would require different positions (I have
commented out the option for page centering).

I hope it helps (since I’m not sure I’m getting your point here),

Sorry, Hans, the full example reads:

  \startbuffer[text]
  
  
  
  \stopbuffer

  \savebuffer[text][sample-text.xml, prefix=no]

  \setupinteraction[state=start]

  \startxmlsetups xml:text
\xmlsetsetup{\xmldocument}
  {pre}
  {xml:copy:html}
  \stopxmlsetups

  \xmlregistersetup{xml:text}

  \startxmlsetups xml:copy:html
\xmltobuffer{#1}{.}{text}
\comment[location=inmargin,buffer=text]{}
  \stopxmlsetups

  \setuppapersize[A9]

  \starttext
\section{one\xmlprocessbuffer{main}{text}{}}

\section{two\xmlprocessfile{main}{sample-text.xml}{}}
  \stoptext

It requires that the source is saved with CRLF line endings (so that
\savebuffer will save that way too), otherwise both \comment will be
exactly the same.

I hope it is clearer now.

Many thanks for your help,

Pablo

Hi Otared

I think what doesn’t work is the dotless i as combining character for i
+ diacritical mark.

It seems that standard i may combine fine:

  \setupinteractionscreen[option=max]
  \starttext
  \startTEXpage[offset=1ex]
  %\i
  %\'{\i}
  %\^{\i}
  \'{i}
  \^{i}
  \stopTEXpage
  \stoptext

And \i outputs a dotless i.

Just in case it helps,

[NTG-context] extra lines in PDF annotations

[Pablo Rodriguez via ntg-context]

Dear list,

using current latest from 2023.03.10 12:18, I have this XML sample:

  

  

  


And the following environment:

  \setupinteraction[state=start]

  \startxmlsetups xml:text
\xmlsetsetup{\xmldocument}
  {pre}
  {xml:copy:html}
  \stopxmlsetups

  \xmlregistersetup{xml:text}

  \startxmlsetups xml:copy:html
\xmltobuffer{#1}{.}{text}
\comment[location=inmargin,buffer=text]{}
\attachment[method=hidden, name=attach.xml, buffer=text]
\null
  \stopxmlsetups

If I save the XML file with Windows EOL chars (CR LF), I get extra blank
lines in the PDF annotation.

Everything is fine, if XML has Unix line endings (LF char).

Attachment contains the proper line ending in each case.

Could anyone confirm what appears to be a tricky issue?

Many thanks for your help,

Pablo

Hi Floris,

  \starttext
  \dorecurse{25}
  {\startTEXpage[offset=1em, pagestate=start]
   \ConTeXt

Many thanks for the check that avoids this issue.

As for the specification in re with boxes larger than the media box:

In theory, trim and crop boxes may be larger than the media box. But the
specification also warns that in that case, “they [would be] effectively
reduced to their intersection with the media box”

In practice, I see that as an issue of logical consistence. I don’t see
a way of cropping or trimming an A5 page inside the boundaries of an A3
page.

Of course, I may be missing something, but I see crop and trim as
synonyms for cut or reduce.

Many thanks again for your help,

Pablo

Sorry, Hans, I copied the wrong sample (value for "width" in
"\setupinteractionscreen" should read "fit" instead of "max"):

  \nopdfcompression
  \setupinteractionscreen
[width=fit]
  \setuplayout
[standard]
[backspace=.7\textwidth,
 cutspace=\cutspace,
 width=middle]
  \starttext
  \startmakeup[page]
  \null
  \stopmakeup
  \startmakeup[standard]
  \null
  \stopmakeup
  \stoptext

Here are the boxes (using current latest from today [2023.03.06 14:48]):

  3 0 obj
  [ 0 0 595.275590072 841.88975789 ]
  endobj

  7 0 obj
  [ 0 0 968.199847496 841.88975789 ]
  endobj

Page 1 (object 4) uses object 3 as /CropBox, /MediaBox and /TrimBox.

Page 2 (object 7) uses object 3 as /MediaBox and object 7 as /CropBox
and /TrimBox (I have just discovered it).

I think it is better to avoid having a page with a /CropBox larger than
its /MediaBox.

But I’m afraid that it is wrong to have a /TrimBox larger than the
/MediaBox for the same page.

I hope it is clear now. Sorry for the mistake in copying the wrong sample.

Many thanks for your reply, Hans.

Sorry, I’m afraid my explanation was poor.

/MediaBox for both pages is [ 0 0 595.275590072 841.88975789 ].

/CropBox for page 1 is [ 0 0 595.27559 841.889758 ] (which is fine, no
problem here).

/CropBox for page 2 is [ 0 0 968.199847 841.889758 ] (which is a much
wider box, converting it from portrait to landscape).

I hope it is clearer now.

[NTG-context] /CropBox overflows /MediaBox

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following source:

  \nopdfcompression
  \setupinteractionscreen
[width=max]
  \setuplayout
[standard]
[backspace=.7\textwidth,
 cutspace=\cutspace,
 width=middle]
  \starttext
  \startmakeup[page]
  \null
  \stopmakeup
  \startmakeup[standard]
  \null
  \stopmakeup
  \stoptext

Boxes are defined in the following objects:

  3 0 obj
  [ 0 0 595.275590072 841.88975789 ]
  endobj

  5 0 obj
  [ 0 0 595.27559 841.889758 ]
  endobj

  8 0 obj
  [ 0 0 968.199847 841.889758 ]
  endobj

Page 1 has /MediaBox redirected to object 3 and /CropBox redirected to
object 5.

Page 2 has /MediaBox redirected to object 3 and /CropBox redirected to
object 8.

I’m not sure whether the oversized /CropBox in the sample above is a
bug triggered by the use of "\setupinteractionscreen[width=fit]".

From the PDF–1.7 specification
(https://opensource.adobe.com/dc-acrobat-sdk-docs/standards/pdfstandards/pdf/PDF32000_2008.pdf#page=636):

  The crop, bleed, trim, and art boxes shall not ordinarily extend
  beyond the boundaries of the media box. If they do, they are
  effectively reduced to their intersection with the media box.

https://wiki.contextgarden.net/PDF_Boxes displays an image of (what I
guess) the ordinary case: /CropBox fits inside /MediaBox.

Could anyone be so kind to confirm the issue or to explain the
rationale behind the oversized /CropBox?

Many thanks for your help,

Pablo

If I’m not missing your point, this would be an email client with

But the issue here is that I forgot to ask whether you would be so kind

Hi Geert,

if you only provide commands, it is really hard to tell what is going on.

Please, always provide complete samples (otherwise, most of the help is
figuring out what the issue is really about).

Hi Geert,

this works for me:

  \definefont[InitialCapFont][name:antpoltcondregular*default sa 4]
  %\setupinitial[style={\switchtobodyfont[helvetica]}]
  \setupinitial[color=red,distance=6pt,n=3, style=\InitialCapFont]

  \starttext
  \setinitial\input zapf
  \stoptext

BTW, I think there is an issue (that might be a bug), when either style
or font are in use, size is not automatically adapted.

Could anyone confirm with the commented line?

Hi Sylvain,

the hard part for the rest of us is figuring out what you may have on
your screen.

\setuphead[subject][before={\blank[preference]}] might help.

Another approach would be \setuphead[subject][after={\blank[samepage,
line]}].

I mean, either you set a preference for breaking pages before \subject
or you force \subject to be on the same page with next paragraph.

Nothing prevents you from doing both.

BTW, default values for before and after in \setuphead[subject] are
\blank[2*big] and \blank (respectively [copied from strc-def.mkxl]).

I hope it might help. It is not clear for me whether the CJK fonts are
only for fragments in these languages or the main text is written in any
of these languages.

I had similar issues with \section and only the Latin script was involved.

Again, I hope it might help,

Hugo,

I have just updated the wiki with another way of line breaking SHA sums:

  https://wiki.contextgarden.net/Wrapping#Line_breaking_with_SHA512_sums

It avoids the issue you encountered and it is an easy workaround.

Just in case it might help,

Sorry, I was trying to find the cause of the issue with SHA sums.

I have just found a workaround and I updated the wiki.

Sorry again for abusing your help (I tend to forget that math is

[NTG-context] custom hyphenator again

[Pablo Rodriguez via ntg-context]

Hi Hans,

with the sample hyphenator from
https://www.pragma-ade.com/general/manuals/languages-mkiv.pdf#page=23,
next letters after hyphenation are missing.

I already reported this
(https://mailman.ntg.nl/pipermail/ntg-context/2023/107743.html).

Am I missing something or have I hit a bug?

Many thanks for your help,

Many thanks for your reply, Hans.

I didn‘t know that it was so complex to do. In fact, I wonder why not
all annotations or links and destinations are copied right.

Now I guess that is way harder than I think.

BTW, Acrobat Reader displays these media. I don’t have access to full
Acrobat either and these annotations work fine in Reader.

[NTG-context] including documents with mediaclips in other documents

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following sample:

  \setupinteraction[state=start]
  \starttext
  \null\page
  \definerenderingwindow[myrenderingwindow]
[width=\textwidth, height=\textwidth]
  \userendering[key-name][audio/mp3][audio.mp3]
[embed=yes, auto]
  \placerenderingwindow[myrenderingwindow][key-name]
  \page
  \null\page
  \stoptext

I want to include the second page in another document.

\externalfigure[document.pdf][page=2, interaction=all] would be the
right command, but it looses the media clip.

A complete sample would be:

  \setupinteraction[state=start]
  \starttext
  \startlayout[page]
  \externalfigure[document.pdf][page=2, interaction=all]
  \stoplayout
  \stoptext

Given this sample, is there any way to include the page (or the whole
document) with the media clip and all its functionalty?

Many thanks for your help,

Hi Tommaso,

I forgot to mention, to avoid path clashes, you may invoke ConTeXt in
the following way (it is only one line and there is no space between lines):

export PATH=~/Documents/ConTeXt/ConTeXt-LMTX/\
tex/texmf-osx-arm64/bin/:$PATH && context source-file.tex

I’m on Linux, so no TeXShop here.

BTW, I’m not sure "luametatex" may work as you intend (without any
format file).

I don‘t think ConTeXt from TeX Live includes LMTX
(https://ctan.org/search?phrase=luametatex).

> Do you have any idea where I might have gone wrong?

My guess is that when you invoke ConTeXt, you are running it from TeX
Live (or from other than the wiki installation).

To check that, what do you get from "which context"?

Which is your output from "context --version"?

My system reads:

  mtx-context | current version: 2023.02.07 19:06

When in doubt run the following (given the paths you provided):

  cd ~/Documents/ConTeXt/ConTeXt-LMTX/
  sh ./install.sh
  cd && context --version

And you should get what my system reads (unless there is an update today).

I hope it helps,

[NTG-context] issue with custom hyphenator

I’m missing m and b in the hyphenated words.

I’m afraid that the hyphenator is all Greek to me.

Is there any reason why letters are lost in hyphenation?

I’m afraid (I think) I might have hit a bug.

Line breaks are removing characters.

In the sample below, output from

reads:

  a

Hans,

I have just checked that these line breakings loose a character in all
options.

The next sample displays the issue clearly:


  \startluacode

--local shared = {
--start  = 1,
--length = 1,
--left   = false,
--right  = false,
--}

   local shared = {
   start  = 1,
   length = 1,
   before = utf.char(0xB7),
   after  = nil,
   left   = false,
   right  = false,
   }

   -- languages.hyphenators.traditional.installmethod("sha",
   -- function(dictionary,word,n)
   -- local t = { }
   -- for i=1,#word do
   -- t[i] = shared
   -- end
   -- return t
   -- end
   -- )

   -- or more efficient when used often:

   -- local all = { }
   -- for i=1,512 do
   -- all[i] = shared
   -- end
   -- languages.hyphenators.traditional.installmethod("sha",
   -- function(dictionary,word,n)
   -- return all
   -- end
   -- )

   -- or more obscure:

   -- local all = table.setmetatableindex({ }, function(t,k)
   -- t[k] = shared
   -- return shared
   -- end)
   --
   -- languages.hyphenators.traditional.installmethod("sha",
   -- function(dictionary,word,n)
   -- return all
   -- end
   -- )

   -- or just (lua is fast enough anyway)

   local all = table.setmetatableindex({ }, function(t,k)
   return shared
   end)

   languages.hyphenators.traditional.installmethod("sha",
   function(dictionary,word,n)
   return all
   end
   )
  \stopluacode

Hi Henry,

not sure I’m getting your point, since this is also a question of
perspective.

What may be named “French spacing” in English may be considered as
“English spacing” in any other European language.

But this is pure TeX
(https://git.savannah.gnu.org/cgit/teximpatient.git/plain/teximpatient/book.pdf#search=null):

  \starttext

I think this may be what you want.

[NTG-context] layout for marked pages?

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following sample:

  \showframe
  \setuplayout[width=middle]
  \definelayout[odd][reset]
  \definelayout[even][reset]
  \doiftext{\markedpages[zapf]}
{\doloopoverlist{\markedpages[zapf]}
  {\definelayout[\recursestring][page]}}
  \starttext
  \dorecurse{50}{\input{knuth}\par}
  \page\startmarkpages[zapf]
\dorecurse{50}{\input{zapf}\par}
  \stopmarkpages\page
  \dorecurse{50}{\input{knuth}\par}
  \stoptext

I wanted to have page layout in pages marked with zapf.

I thought \markedpages[zapf] was the way to go, but I only get text
after marked pages, not before them.

Which is the right approach to have marked pages with a different layout?

I would be happy to update
https://wiki.contextgarden.net/Page_Layout#Multiple_layouts.

Many thanks for your help,

Pablo

[NTG-context] list not following "focus=standard"?

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following sample:

  \setupinteraction[state=start, focus=standard]
  \starttext
  \completecontent
  \dorecurse{25}
{\section{Section}
  a\footnote{b}}
  \stoptext

Using current latest (from 2023.01.26 18:34), destinations for TOC are
pages (/D [ 7 0 R /Fit ]) and destinations for footnotes are named
destinations (/D [ 1 0 R /XYZ 61.900625 141.0443 null ]).

Compare https://pdf.ousia.tk/lst-fnt.pdf#_3 with any link from the TOC.

I‘m afraid this might be a regression from a recently fixed issue.

Could anyone confirm this issue?

Many thanks for your help,

Pablo

Hi André,

as far as I know, this may be a bug in PDF.js.

Could you report it to the developers (https://github.com/mozilla/pdf.js)?

Many thanks for your help,

Pablo

When I faced a similar task, I thought it could be the way of solving
the issue (how to copy and paste ConTeXt code and console commands).

Using Fedora 37 (and having just installed Okular), I see that
annotations are tricky to open in Okular.

First you have to select the Annotations tab on the left pane, go to the
annotation and then right-click on it to open (the pop-up note).

Evince has a more effective approach: double-clicking on the icon opens
the note (afaIk, this is similar to Acrobat).

I hope this helps,

Pablo

Hi André,

I wonder whether I’m getting your point with the following sample:

  \showframe
  \setupinteraction[state=start]
  \starttext
  \startbuffer[abc]
  def foo(x):
  if x == 0:
  bar()
  else:
  baz(x)
  foo(x - 1)
  \stopbuffer
  \comment[location=leftmargin,
space=yes,
buffer=abc,
title={Python code}]
{}\typebuffer[abc]
  \stoptext

This might solve what you need. At least, this is the approach that I
use to provide text that can be directly copied.

I’m on Linux and last time I tested on Windows there were extra lines in
the comments.

Just in case it might help,

Pablo

Hi Julian,

\setupnote[footnote][location=none] might help.

Since you don’t provide a minimal sample to play with, I cannot tell
whether this works or not.

Just in case it helps,

Pablo
