Hi Gerben,

it only seems to work inside math:

  \starttext
  \dorecurse{26}{$\blackboard\characters{\recurselevel}
  \Characters{\recurselevel}$}
  \stoptext

I hope it helps,

Hi Michal,

I haven’t found the time to check this, but this is pretty much what I
wanted: being able to set other timezones than the local one.

[NTG-context] vertical align in combination

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following sample:

  \starttext
  \setupexternalfigure[location=default]
  \startcombination[nx=3, ny=2, location={middle}]
  {\externalfigure[mill.png][width=.25\textwidth]}
  {\externalfigure[cow.pdf][width=.25\textwidth]}
  {\externalfigure[cow.pdf][width=.25\textwidth]}
  {\externalfigure[spider.eps][width=.25\textwidth]}
  {\externalfigure[hacker.png][width=.25\textwidth]}
  {\externalfigure[mill.png][width=.25\textwidth]}
  \stopcombination
  \stoptext

The first line has the images vertically centered, but the second line
has them aligned to the top. Using "align=middle" made no difference.

How could I get all lines with images vertically centered?

Many thanks for your help,

Pablo

A more visual version for me would be:

Is there a way to add time and timezone in backend.date?

Many thanks for this fix too.

Sorry for insisting, but could you check what is wrong with an extra
blank space in rotated imposition
(https://mailman.ntg.nl/pipermail/ntg-context/2021/103909.html)?

Many thanks for the fix. It would be great that current timezone doesn’t

[NTG-context] \rotate[rotation=270] adds extra vertical space

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following imposition sample:

  \startbuffer[newbuff]
  \showframe\showgrid
  \setuppapersize[A3, landscape]
  \setuplayout[width=middle]
  \starttext
  \dorecurse{4}{\null\page}
  \stoptext
  \stopbuffer
  \startmode[*first]
  \savebuffer[newbuff][A3page.tex, prefix=no]
  \executesystemcommand{context --purgeall A3page.tex}
  \stopmode
  \showframe
  \setuplayout[page]
  \setuppapersize[A5][A4, landscape]
  \setuparranging [2UP]
  \setupinteractionscreen[option={landscape, paper}]
  \starttext
  \doiffile{A3page.pdf}
  {\def\Doc{A3page.pdf}
  \getfiguredimensions[\Doc]
  \dorecurse{\noffigurepages}
{\ifodd\recurselevel
  \rotate[rotation=90]
{\externalfigure[\Doc][page=\recurselevel, width=\textheight]}
\else\rotate[rotation=270]
{\externalfigure[\Doc][page=\recurselevel, width=\textheight]}
\fi}}
  \stoptext

I’m afraid that if rotation values are 270 or 180, the imposed page has
an extra vertical space before.

I think this might be a bug. Or I don’t know what I might be missing.

Many thanks for your help,

Hi Michal,

many thanks for your fast reply.

I would like to import both metadata values (CreationDate and ModDate)
from another file (such as https://pdf.ousia.tk/metadata.pdf).

Besides from the fact that LMTX doesn’t work with this (only MkIV does
[already reported]), isn’t no simpler way to get ISO 8601 formatting
from doc.Info.ModDate than the following one?

  \starttext
  \startluacode
  function document.transfer_metadata(name)
local main_doc = lpdf.epdf.load(name)
context.setupinteraction{ title = main_doc.Info.Title }
context.setupinteraction{ date =  main_doc.Info.ModDate:sub(3,6) ..
"-" .. main_doc.Info.ModDate:sub(7,8) .. "-" ..
main_doc.Info.ModDate:sub(9,10) .. "T" ..
main_doc.Info.ModDate:sub(11,12) .. ":" ..
main_doc.Info.ModDate:sub(13,14) .. ":" ..
main_doc.Info.ModDate:sub(15,22):gsub("'", ":") }
context(main_doc.Info.Title .. "\\par")
lpdf.epdf.unload(name)
  end
  \stopluacode
  \unexpanded\def\TransferMetadata#1%
{\ctxlua{document.transfer_metadata("#1")}}
  \startTEXpage[offset=1em, align=center]
  \TransferMetadata{metadata.pdf}
  \stopTEXpage
  \stoptext

> environment variable, but I am not succesfull with it right now.

It would be fine to ble able to set CreationDate. Otherwise, having a
ModDate prior to CreationDate gives a weird impression.

Many thanks for your reply, Hans.

This works in MkIV, but not in LMTX:

 context.setupinteraction { title = main_doc.Info.Title }

BTW, is there a way to add CreationDate and ModDate?

[NTG-context] read PDF metadata from other file

[Pablo Rodriguez via ntg-context]

Dear list,

I have the following sample:

  \starttext
  \setupinteraction
[state=start,
 title={\cldcontext{pdfe.open("b.pdf").Info.Title}}]
  \null
  \stoptext

From a document composed with \insertpages, I need to transfer medatada.

But I get the raw value "feff0061" (which I guess it may be introduced
by lpdf.pdfunicode).

How can I get the pure text value, so I can transfer metadata from one
PDF document into another PDF document?

Many thanks for your help,

Sorry, Christian, I’m afraid I don’t understand what you want to achieve

\startTEXpage[pagestate=start] uses page numbers as any other page.

Hi Tomáš,

well, I wnanted to remove the ending period in both cases (and to
understand how that patterns might work.

I got the first one with:

  context("2a ok. " .. url:match "[^/]+.+/") -- path and name

But I’m stuck at the second one (sorry, I don’t know how to remove the
final period):

  context("2c. " .. url:match "[^/]+.$":match("^.+%l+[.$]"))

https://pragma-ade.com/general/manuals/cld-mkiv.pdf#search=nameonly is
the way to go, but it won’t hurt me to understand how patterns might
work here.

I’m afraid I don’t know how to make the commands work:

  \setupexternalfigures[location=default]
  \definelayer[hi]
   [x=.5\dimexpr\framedwidth\relax, y=.5\dimexpr\framedheight\relax]

  \externalfigure[cow-brown]\framedheight}
  \stopTEXpage
  \stoptext

In this case, \getfiguredimensions would work, but I don’t know how to
deal with a pure text box.

BTW, is there a way to have TEXpages numbered? "pagestate=start" seems
not to work here.

[NTG-context] compression for multimedia objects

[Pablo Rodriguez via ntg-context]

Hi Hans,

some days ago (after the patch from
https://mailman.ntg.nl/pipermail/ntg-context/2021/103011.html), I
included two mp4 files in a PDF document.

They where so generated, that they could be compressed in a zip file
from 254MB into less than 25MB. The resulting PDF file was less than 25MB.

With the current latest, compression for multimedia objects is disabled.
The same PDF document takes about 254MB.

I don’t know whether this is intended. In that case, could we have an
option to compress embedded multimedia objects?

(I know that those mp4 files are crappy, but I can’t control the crap
others generate.)

Many thanks for your help,

Re: [NTG-context] How not to display the header of the chapter page on the page with the table of contents ?

Hi Fabrice,

I have never used projects and chapters (or whatever the right name is).

I’m not sure I get what you’re experiencing: with a single chapter, do
you have the fancy layout or not?

It would make sense that the fancy chapter doesn’t appear only compiling
a chapter. I guess there is no \startbodymatter...\stopbodymatter
wrapping it.

Another approach would be:

\setuphead
   [chapter]
   [align=flushright,
textcommand=\groupedcommand{\blank[medium]}{},
numbercolor=darkgray,
textstyle=ChapterTextStyle,
numberstyle=ChapterNumberStyle,
before=\startChapterFrame,
after=\stopChapterFrame,
header=high]

\setuphead
  [title]
  [header=empty,
   align=,
   textcommand=,
   textstyle=,
   style=\tfc,
   before={\blank[2*big]},
   after={\blank[2*big]}]

I hope it helps,

Pablo

Then use frontmatter and bodymatter.

I don’t know why I get the following message:

It seems to be caused by "app.media.openPlayer", but the code is copied
from the documentation Adobe released early this year.

Does anyone know what is wrong here or what am I missing?

Many thanks for your help in advance,

Re: [NTG-context] Setting a heading text on its own page with \setuphead

Hi Joey,

these are options for \setuphead[part] (MyPart in your case):

number=no.

This is the default for \setuphead[part] (only noticeable in doublesided
documents).

style is the right option there.

placehead=yes is required for \setuphead[part]. And also for MyPart.

header=empty and footer=emtpy. For the page break before the body text,
you need after=\page.

[NTG-context] issue with footnote in TOC

[Pablo Rodriguez via ntg-context]

Dear list,

compiling the following sample with current latest (2021.08.04 17:51):

  \starttext
  \completecontent
  \chapter{Chapter Title\footnote{With footnote}}
  \stoptext

The entry in the TOC for the chapter seems to have problems with the
footnote command (backslash seems to be unrecognized).

Would anyone be so kind to confirm the issue? I’m afraid it might be a
bug in current latest.

[NTG-context] copies from \setupinteractionscreen not working?

Dear list,

[NTG-context] issue with signature fields in Acrobat

[Pablo Rodriguez via ntg-context]

Hi Hans,

I have the following sample:

  \setupinteraction[state=start]
  \starttext
  \startTEXpage[offset=2em]
  \setupfield[ShortLine][horizontal][width=5cm,height=5em]
  \definefield [Email] [signature] [ShortLine]
  \field [Email] [your email]
  \stopTEXpage
  \stoptext

If I sign it with Acrobat Reader, Times New Roman is used instead of
MyriadPro (which is the default font used by Acrobat for signing).

Line 945 from lpdf-fld.lmt contains:

  if #collected > 0 then
  local acroform = pdfdictionary {
  NeedAppearances = pdfmajorversion() == 1 or nil,
  Fields  = pdfreference(pdfflushobject(collected)),
  CO  = fieldsetlist(calculationset),
  }
  if sometext or somefont then
  checkpdfdocencoding()
  if sometext then
  usedfonts.tttf = fontnames.tt.tf
  acroform.DA = "/tttf 12 Tf 0 g"
  end
  acroform.DR = pdfdictionary {
  Font = registerfonts(),
  Encoding = pdfdocencodingcapsule,
  }
  end
  lpdf.addtocatalog("AcroForm",pdfreference(pdfflushobject(acroform)))
  end

Would it be possible that the second conditional ("if sometext or
somefont") could be only applied if Fields doesn’t refer to signatures?

Otherwise, Acrobat will use the font specified in the dictionary. Among
other things, this breaks PDF/A documents, since the font for the
signature isn’t embedded.

Many thanks for your help,

Pablo

Sorry, Jeroen, this was my fault.

A simpler approach to the command above reads:

  \savebuffer[list=slides, file=slides.tex]

But then you have to invoke the file as

  \typesetfile[\jobname-slides.tex][--purgeall][object=no, width=0pt]

and the output file would read:

  \getfiguredimensions[\jobname-slides.pdf]
  \dorecurse{\noffigurepages}
  {\startTEXpage
\externalfigure[\jobname-slides.pdf][page=\recurselevel]
   \stopTEXpage}

I mean, you get hyphen instead of underscore.

I hope it may help,

Thunderbird’s display is in the attached image.

The message list can only include a sender, since it has registered the

I think this behaviour makes most sense.

Hi Jeroen,

not sure this might help you (I’m not sure you intend a single source
file, in addition to a single PDF document), but here you have:

  \startbuffer[slides]
  \setuppapersize[CD]
  \setupbodyfont[60pt]

  \dorecurse{25}
  {\startmakeup[standard][pagestate=start, style={\ss\bf}, align=center]

  \stoptext

BTW, I cannot get simpleslides working with LMTX.

\externalfigure is your friend here and there is no need to convert the
slides to PNG (see above).

Hi Otared,

  Reply-To: mailing list for ConTeXt users 
  Cc: Otared Kavian

Before they read:

  From: Otared Kavian 
  To: mailing list for ConTeXt users 
  Reply-To: mailing list for ConTeXt users 
  Errors-To: ntg-context-boun...@ntg.nl
  Sender: "ntg-context" 

I experience the same problem as yours.

Before, replying in Thunderbird (Ctrl+r) generated a private reply. I
needed to generate a reply to the list (Ctrl+Shif+l).

Right now, Ctrl+r generates a reply to the list.

It seems that there is no perfect solution to this. I mean, having both
messages sent from original sender and replied by default to the list.

I guess that this might be achieved finetuning Mailman (but I don’t know
how).

I hope it helps,

Many thanks for your code update, Michal.

I’m extremely interested in investigating the possibilities this opens.

But I’m afraid that I will have other things to do first. It will take
me months to come back to this again.

Many thanks for the patch.

It would be also great to have an option not to list some files as
embedded (adding a option "list" to "\useexternalrendering" such as in
"\useexternalrendering[myvideo][video/mp4][video.mp4][embed=yes, list=no]").

Being the default to yes, I’m thinking of cases where there is a risk
distributing the multimedia file without the embedding document, because
of the lack of context (no pun indented)

[NTG-context] multimedia PDF in ConTeXt

[Pablo Rodriguez via ntg-context]

Hi Michal and Hans,

many thanks for your patch to fix multimedia objects in PDF and your
extremely interesting and in-depth explanation about multimedia in PDF.
Many thanks to Hans for the release of an updated latest with also
updated documentation.

Although I don’t read Czech, just out of curiosity, is your bachelor
thesis available on the net, Michal? Thanks to theses.cz, I found
https://is.muni.cz/th/t8qpp/DP_Vlasak_Michal_2015.pdf (only a name
coincidence, I guess).

Using your sample, I have two questions:

  \starttext
  \setupinteraction[state=start]

  \useexternalrendering[myvideo][video/mp4][video.mp4][embed=yes]

  \definerenderingwindow[myrenderingwindow]
[width=\textwidth, height=\textwidth]

  \placerenderingwindow[myrenderingwindow][myvideo]
  \stoptext

Is there no way to have the video as an embedded file in the PDF
document? (I mean, that the file is listed when the attachment panel is
displayed.)

The second question is addressed to Hans: would it be possible that
\placerenderingwindow could have another option and text as in \framed?
A workaround would be to add a layer, but too complex only for adding
usage instructions for the media usage.

Many thanks for your help,

  \startxmlsetups xml:testsetups
   \xmlsetsetup{#1}{*}{-}

I need to check whether the link is inside the same div or not.

I know how to obtain the destination identifier (\xmlreffatt{#1}{href}
and I know how to obtain the identifier of the contaning div

But I don’t know how to ge the identifier of the div which contains the

How could I get that?

Hi Gerben,

this might be what you need:

  % Every chapter body text starts with a drop cap:
  \setupindenting[yes, medium]

  \starttext
  \chapter{Chapter}

  \placeinitial So it was. \input knuth

  \placeinitial So it was. \input knuth

  \noindentation
  \placeinitial So it was. \input knuth
  \stoptext

Sectioning commands never indent next paragraph by default. You have to
type either \setuphead[chapter][indentnext=yes] or
\setupheads[indentnext=yes] to enable it.

If every chapter starts with an initial,
\setuphead[chapter][after={\blank[2*big]\placeinitial}] enables this
automatically (\blank[2*big] is the default command after chapter).

Please, avoid adding questions after a multiline signature (because the
lines might be look like belonging to the signature, and not as a
question to the list).

This might help in LMTX:

  \definefontfeature[allcaps][uppercasing=yes]
  \starttext
  \startTEXpage[offset=1em]
  {\feature[+][allcaps]\bf uppose we}
  \stopTEXpage
  \stoptext

I hope it helps,

Hi Kurt,

I think this might be what you intend:

   \setupcaption[table][number=no]

   \starttext
   \startplacetable[title={Table With A Caption},location=force]
 \bTABLE
 \bTR\bTD r2c1 \eTD\bTD r2c2\eTD\eTR
 \eTABLE
   \stopplacetable
   \stoptext

As to your quetsion, I have no idea why this happens.

Just in case it might help,

Hi Gerben,

\setupinitial is your friend.

i-context.pdf (included in LMTX) contains the available options
(searching for "\setupinitial [", without quotation marks).

I hope it helps,

Hi Charles,

I think that "inright" is what you want:

  \setuppagenumbering[alternative=doublesided,
  location=inright]

  \starttext
  \dorecurse{20}{\input knuth }
  \stoptext

With current latest from 2021.07.10 21:51, "location=inright" behaves as
you expect using LMTX.

Using MKIV with the current latest, there is no difference between
"location=inright" and "location=inmargin".

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

I hope it might help,

Hi Ajith,

as Aditya mentioned, this version is too old (maybe it even lacks the

This old version won’t be fixed now (I’m afraid).

Hi Ajith,

I don’t have any idea about Malayalam (or any other Indic language [I
can deal with Latin and Greek scripts only, I’m afraid]), but this seems
to work fine.

\mainlanguage[ml]
\definefontfamily [malayalam] [rm] [RIT Rachana]
[features=malayalam-two]
\setupbodyfont [malayalam]
\starttext
\tf അദ്ധ്യായം\\
\em അദ്ധ്യായം\\
\bf അദ്ധ്യായം\\
\em അദ്ധ്യായം
\stoptext

Fonts are RIT Rachana from http://www.rachana.org.in/.

The relevant feature here malayalam-two. I used serif (or rm), since the
font looked to me more serif than sans-serif (Latin glyphs are clearly
from a serif font).

I would say that with malayalam-two ligatures are the same ones as in
LibreOffice.

[NTG-context] xtable as list item (again)

[Pablo Rodriguez]

Dear list,

I already posted a similar question some time ago
(https://mailman.ntg.nl/pipermail/ntg-context/2021/101021.html), but I
got no reply.

I have the following sample:

  \showframe\showstruts
  \starttext
  \startitemize[n][margin=yes]
  \item a
  \item
\startembeddedxtable[option={stretch, width}]
\dorecurse{25}{\startxrow
  \startxcell \Characters{\recurselevel}\stopxcell
  \startxcell \characters{\recurselevel}\stopxcell
\stopxrow}
  \stopembeddedxtable
  \item b
  \stopitemize
  \stoptext

And I get two issues:

1. Item number in 2 is placed on the bottom of the xtable. I need it on
the top of the xtable.

2. There is an extra horizontal space before the xtable. How can I get
rid of it? (In my real-world document, the space before is huge. In any
case, it misplaces the xtable.)

Maybe my approach is wrong, but I need the xtable as part of a list (and
I need it to strecht it horizontally).

Does anyone know how to achieve this?

Many thanks for your help,

Pablo

Many thanks for the new latest, Hans.

I have compiled the sample from page-ffl.mkxl:

  \starttext
  \definefacingfloat
  [whatever]

  \setupfacingfloat
  [whatever]
  [style=bold,
   width=frame,
   offset=10pt,
   color=white]

  [background=color,
   backgroundcolor=red]

  \setupfacingfloat
  [whatever:right]
  [background=color,
   backgroundcolor=green]

  \startfacingfloat[whatever]
{\dorecurse{10}{\samplefile{tufte} }}
{\dorecurse{10}{\samplefile{ward}  }}
{\dorecurse{10}{\samplefile{tufte} }}
{\dorecurse{10}{\samplefile{ward}  }}
  \stopfacingfloat

  \startfacingfloat[whatever]
\startcontent \dorecurse{10}{\samplefile{tufte} } \stopcontent
\startcontent \dorecurse{10}{\samplefile{ward}  } \stopcontent
\startcontent \dorecurse{10}{\samplefile{tufte} } \stopcontent
\startcontent \dorecurse{10}{\samplefile{ward}  } \stopcontent
  \stopfacingfloat

  \dorecurse{10}{\samplefile{sapolsky} }
  \stoptext

I’m afraid that the resulting PDF document only contains the text from
Sapolsky (no facing floats).

Sorry, but I have no idea about what I may be doing wrong (or whether
there is an issue here).

Many thanks for your help,

Hi Hans,

many thanks for the new upload.

I’m afraid that now slanted for New Computer Modern Mono doesn’t work:

  \mainlanguage[agr]
  \setupbodyfont[newcomputermodern]
  \starttext
  {\tt\bi\input aristotle-grc\par}
  \tt\it\input aristotle-grc\par

"newcmmono10-oblique.otf" is actually "newcmmono10-italic.otf". Naming
isn’t consistent in those fonts (italic and bold oblique, I’m afraid).

Many thanks for the new latest, Hans.

The following sample shows an issue with "newcmmono10-bolditalic.otf":

  \mainlanguage[agr]
  \definefontfamily[another][rm][Another]
[tf=file:newcmmono10-boldoblique.otf]
  \setupbodyfont[newcomputermodern]
  \starttext
  \tt\bi\input aristotle-grc\par
  \switchtobodyfont[another]
  \input aristotle-grc\par
  \it\input aristotle-grc
  \stoptext

I’m afraid that there is no "newcmmono10-bolditalic.otf", but
"newcmmono10-boldoblique.otf".

The following patch fixes the issue:

Hi Leo,

Acrobat for Linux is available (although the version is too old) at
ftp://ftp.adobe.com/pub/adobe/reader/unix/9.x/9.5.5/enu/.

Acrobat isn’t able to deal with the signature annotation and with the

Here is a description:
https://www.adobe.com/content/dam/acom/en/devnet/pdf/PDF32000_2008.pdf#search=4.35
(link should work with Firefox).

But you might check yourself with the following sample:

  \setuppapersize[A10, landscape]
  \setuplayout[page]
  \setupinteraction[state=start]
  \starttext
  \setupfield[sl][horizontal]
[frame=on, width=\textwidth, height=\textheight]
  \definefield[x][signature][sl]
  \field[x]
  \stoptext

The attached certificate has the password 123456.

Only mupdf-gl sees the signature annotation after signing it. Acrobat,
Evince, Okular and xpdf cannot deal with the signature.

https://validator.docusign.com/ gives a warning:

  This document doesn't have any digital signatures.

I hope it might help,

mupdf-gl signs the document, but in a way that only mupdf-gl understands it.

Try to open a PDF document signed with mupdf-gl in Acrobat (Reader or
not). You will see that the signature is wrong.

Sorry, objects is a very special term in PDF parlance. It has nothing to

[NTG-context] issue with link (MkIV & LMTX)

[Pablo Rodriguez]

Dear list,

I have the following sample:

  \setuppapersize[A10]
  \setupinteraction[state=start]
  \enabledirectives[references.border]
  \unexpanded\def\MyURL#1%
{\bgroup\goto{{\tt\hyphenatedurl{#1}}}[url(#1)]\egroup}

  \startTEXpage[offset=1ex]
  \startitemize
  \item \MyURL{a.b\\/c.d\letterhash e}
  \stopitemize
  \stopTEXpage
  \stoptext

I’m using current latest from 2021.06.04 17:28.

LuaTeX generates the link rectangle right.

LuaMetaTeX generates a wrong link rectangle.

In the attached image, you can see the output I get (MkIV and LMTX).

Could anyone confirm the issue?

I mean, I would like that the output reads:

Which would be the way to do it automatically?

BTW, in my real--world document, I need to remove part and chapter

Hans,

at least on Linux64, if I compile a source file named "mwe.tex", I get
an extra "mwe-pdf-keep.pdf", either with or without invoking the option
"--purgeall".

This happens both with MkIV (LuaTeX 1.13 7420 + ConTeXt MkIV 2021.06.04
17:28) and LMTX (LuaMetaTeX 2.09 20210531 + ConTeXt LMTX 2021.06.04 17:28).

Contents seem to be irrelevant, but actual contents of "mwe.tex" read:

  \starttext
  \input zapf
  \stoptext

I’m afraid that this might be a bug.

Many thanks for your help,

Pablo

Just a comment. I also experienced problems in Linux with --luatex some
days ago.

I got everything right with current latest (2021.05.27 14:15).

I would erase the cache and try it again:

  mtxrun --script cache --erase && mtxrun --generate

I’m not a Linux expert at all. But this might help.

It doesn’t make any difference in the text spacing (searching and
copying) in the minimal sample.

I wish I could. PDF annotations are a mess in MuPDF (this affects
versions from 3.2).

PDF annotations in SumatraPDF-3.3 are huge, even preventing the text
from being readable. And they are always printed (since all contain "/F
4"), no matter that no appearance dictionary allows to print them.

I have already discussed that with people from Artifex, but it seems
that they won’t change their mind about this.

It would be helpful that PDF annotations in ConTeXt with no associated
appearance dictionary could have "/F 0" (so that MuPDF doesn’t print them).

Many thanks for your help,

It works perfectly fine, but not with font expansion:

  \definefontfeature
[default]
[default]
[expansion=quality]
  \setupalign
[hz]

  \setuppapersize[A6]
  \setupbodyfont[pagella]
  \setupbackend [space=yes]
  \starttext
\input zapf
  \stoptext

It works fine now.

A minor issue happens with SumatraPDF-3.1.2 (aside from font advance):

  \setuppapersize[A6]
  \definefontfamily[mainface][rm]
  [TeX Gyre Pagella]
  \setupbodyfont[mainface]
  \starttext
\input zapf
  \stoptext

Lines 3, 7, 10, 12 and 13 lack spaces between words:

  Coming back to the use of typefaces in
  electronic publishing: many of the new
  typographersreceivetheirknowledgeand
  information about the rules of typogra-
  phy from books, from computer maga-
  zines or the instruction manuals which
  theygetwiththepurchaseofaPCorsoft-
  ware. There is not so much basic instruc-
  tion, as of now, as there was in the old
  days,showingthedifferencesbetweengood
  and bad typographic design. Many peo-
  plearejustfascinatedbytheirPC'stricks,
  andthinkthatawidely--praisedprogram,
  called up on the screen, will make every-
  thing automatic from now on.

Although this only happens with SumatraPDF, it would be great to have
standard spacing (otherwise searching is impossible).

Many thanks for your help,

Pablo

Many thanks for your ultra-fast fix, Hans.
