[NTG-context] (XeTeX) trouble debugging a Missing number error
Hi all,
I'm working with some code that was developed by someone else.
The document I'm typesetting is now giving the following error:
! Missing number, treated as zero.

I haven't been able to figure out what's wrong or how to fix it.
I had just made changes to refactor the definitions of fonts. (I
confirmed that these changes really are a necessary cause of the error:
when I back out just these changes, the error goes away.)
From the above error message I understand the error was detected during
the expansion of \startabblist. Here's the definition of abblist:
% Abbreviations
\definestartstop
[abblist]
[before={\setupbackgrounds[text][background=verticalline]
\starttextbackground[text]
\setuptab[headstyle={\switchtobodyfont[SansB,\SansBsize]},width=20mm,location=left]
\startcolumnset[abbcolumn] \startalignment[flushleft,nothyphenated]},
after={\stopalignment \stopcolumnset \stoptextbackground
\setupbackgrounds[text][background=off]}]
From that, one might guess that the font SansB or the font dimension
\SansBsize were the problem. But those definitions haven't changed
(though I would like to confirm that empirically with a run-time trace
message).
Here are the font settings changes that did occur:
E16fonts.tex:
changed this block:
\definefont[SerifXLI][name:GentiumBookBasic-Italic at 10pt]
\definefont[SerifXXL][name:GentiumBookBasic at 12pt]
\definefont[SerifXXLB][name:GentiumBookBasic-Bold at 12pt]
to use size dimensions defined elsewhere:
\definefont[SerifXLI][name:GentiumBookBasic-Italic at \XLfontsize]
\definefont[SerifXXL][name:GentiumBookBasic at \XXLfontsize]
\definefont[SerifXXLB][name:GentiumBookBasic-Bold at \XXLfontsize]
E16settings.tex: I added these definitions:
\define\XLfontsize{14pt}
\define\XXLfontsize{16pt}
There are modes involved, so things are a bit more complicated, but I
believe that is the only effective difference.
I also created a log file, which I'll attach.
There is also a version with \tracingmacros=1, but it's 600K, so I'll
put it at
http://www.huttar.net/tmp/country-report-country_id-15-tracing.log
Thanks for taking a look. Please let me know what further information I
need to provide.
I can provide the .tex files themselves upon request.
I would especially like to know better techniques for debugging -- how I
can induce TeX/ConTeXt to tell me more about what's going on. I realize
that as a macro language, this is inherently difficult with TeX.
We are heavily invested in XeTeX, so switching to LuaTeX in the near
term is not an option.

you can try

[before=\StartAbbList,

Thanks, I will try this.
Is the goal of this change to fix the error? To help diagnose it?
I don't really understand the use of \unexpanded.
After making this change, the behavior is unaffected... I still get the
Missing number error, etc.
in such case best make a small example, for instance how is abblist used?
\startabblist{
\tab{\ITC{alt.}}\AE{alternate name for}\par
...
\tab{USDS}\AE{US Department of State}\par
}\stopabblist
where \AE is defined as:
\def\AE#1{\hskip -3mm \SerifL{#1} \vskip 1mm}

// E16settings.tex: I added these definitions:
// \define\XLfontsize{14pt}
// \define\XXLfontsize{16pt}
//
// There are modes involved, so things are a bit more complicated, but I
// believe that is the only effective difference.
/
and how about:
\def\XLfontsize{14pt}
\def\XXLfontsize{16pt}
I will try that, but all our font size definitions have always used
\define, and it used to work fine without errors.
On http://wiki.contextgarden.net/Command/define it says that \define is
like the TeX primitive \def, but will print an error to the log file if
the new definition overwrites an existing command.
I checked the log file, and there is no error mentioning XLfontsize.
So the purpose of your suggestion is to remove the possibility of
reporting a duplicate definition? (There's probably more to it than that
- I'm just trying to understand.)
I tried changing \define to \def as you suggested. The result was
unchanged - same error.

Lars

Re: [NTG-context] (XeTeX) trouble debugging a Missing number error
In response to Hans Hagen and Wolfgang Schuster's messages of Dec. 5, Just to let you know, in response to your messages, I am working a small, self-contained example that reproduces the problem. However I have been asked to focus on a different project for a few days, so ... please don't interpret my silence as We asked him to do due diligence and he never answered. :-) Hopefully I'll be back with more, next week. Regards, Lars ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : http://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___
[NTG-context] Missing number, treated as zero error when using \definefont with \define'd dimension
Hello,
I reported a Missing Number error back in December (thread at
http://www.ntg.nl/pipermail/ntg-context/2012/070471.html) but got
sidetracked on another issue before finding a resolution.
Now I'm back to the Missing Number error, and I have a short example
that reproduces it:
\define\largefontsize{13pt}
% Works fine: \definefont[SerifL][Arial at 13pt]
% Leads to error:
\definefont[SerifL][Arial at \largefontsize]
% Missing number, treated as zero error thrown on the following line:
\starttext \SerifL{Hello} \stoptext
Note that the SerifL font definition works fine (no error) if I
hard-code in 13pt instead of using an intervening \largefontsize
definition. But if I hard-code the point size, it would hamper the
modularity of our font configuration and the use of modes in which
different size fonts are used.
Maybe \define is just the wrong command to use when creating an
identifier for a specified dimension?
I tried changing it to \def and the error went away!
I looked up the documentation of \define
(http://wiki.contextgarden.net/Command/define) and \def, and couldn't
find any obvious difference, except that \def is TeX and \define is
ConTeXt. The wiki page I just linked to mentions differences between
MkII and MkIV, but this error occurs in both (in XeTeX and LuaTeX).
Can someone help me understand why I should not use \define for this
case? (Or in general, when I should not use \define?) Or does the
problem lie somewhere else?
Thanks,
Lars

[NTG-context] Missing number error, related to setupcolumnsetlines
Hello,
I've got a Missing number error, treated as zero. I've whittled the
problem code down to this minimal example:
\definecolumnset [abbcolumn] [n=2,distance=5mm,balancing=yes]
\setupcolumnsetlines[abbcolumn][1][1][60]
\setupcolumnsetlines[abbcolumn][1][2][60]
\starttext
\startcolumnset[abbcolumn]
foo
\stopcolumnset
\stoptext
By contrast, if I remove the \setupcolumnsetlines commands, the error
goes away. (But I think I need those commands, in case the text has more
than 60 lines.)
Also, if I run the example shown on this page
http://wiki.contextgarden.net/Command/setupcolumnsetlines
which seems very similar to mine, it works fine; no errors.
Based on the latter working example, I tried adding the following to my
minimal example that fails:
\switchtobodyfont[small]
or
\setupcolumnsetstart[abbcolumn][1][1][1]
\setupcolumnsetstart[abbcolumn][1][2][1]
but neither one solved the problem.
Here is more of the error output I received when running TeX on the
minimal example shown at the start of this email:
! Missing number, treated as zero.

[NTG-context] error: terminal: NOfTextColumns-1, ! Improper final value has been replaced by 0

This error is very odd because:
a) The only place I can find code mentioning NOfTextColumns-1 is in
mp-core.mpii, where it's commented out!
% \startuseMPgraphic{whatever}
% for i=1 upto NOfTextColumns-1 :
% draw (rightboundary TextColumns[i]) shifted ...
But maybe I just haven't been looking in the right places.
b) The place in my .tex document where the error occurs, line 27, is at
a \stopptp. Yet there is an essentially identical start/stopptp earlier
in the document, where no such error is thrown:
\startptp{
\pagereference[Summaries]\pnum{Part I}\ptitle{Statistical Summaries}
}\stopptp
So I guess there's some content in between the two starts/stop ptp's
that's laying the stage for the error to occur.
I'll be working on a minimal example, but that's time-consuming; and I
thought in the meantime, there may be some clues in the above
information that could help clarify the nature of the problem, to
someone who understands the inner workings of ConTeXt.
Thanks for any help,
Lars

[NTG-context] section headings on a grid: less space above?
Hello,
I'm using mkii to typeset a document with grid layout. I'm trying to
configure the formatting of the subsection headings.
I have the following setuphead:
\setuphead[subsection][number=no,style={\switchtobodyfont[SansB,\subheadersize]},grid=top]
This works successfully in that the lines below the heading are aligned
to the grid.
But what I'm trying to change is the fact that 4 grid lines are taken up
by the heading: approximately two blank lines above, and one below. The
requirement is to use 3 grid lines.
I know how to move the heading text down within the space:
grid=3pt
does that.
But I can't figure out how to reduce the number of lines above the
heading text.
The document at http://www.pragma-ade.com/general/manuals/details.pdf
says that the top option (as in grid=top) means add/remove an extra
line to the top. But in my experimenting, the presence or absence of
top seems to make no difference.
I also tried:
grid={broad,low}
grid={fit,low}
grid={line,3pt}
grid=standard
no grid setting at all
but none of these seems to reduce the total amount of vertical space
taken up by the heading.
Can somebody tell me how to do this? E.g. how to make the top option
remove an extra line on top?
Thanks,
Lars
P.S. version:
ConTeXt ver: 2008.05.21 15:21 MKII fmt: 2009.1.20
but I'm hoping the oldness of the version isn't a factor here.

Thank you very much, that worked!
Can you explain how it works?
Does before= override the setting of grid=? Is before= at a lower
level?
Yet before= must be at a high enough level that the grid-setting code
is able to adjust for it and still preserve the grid alignment...

[NTG-context] flow text around graphic: lower right
Hi all,
We have the small self-contained example below, in which text flows
around a graphic.
The graphic is aligned with the upper-left corner of the text paragraph
(despite \setuphanging[location=right]). We would very much like to have
the graphic align with the lower right corner of the paragraph.
Is there any way to do that?
\definecolumnset[TwoColumns][n=2]
\setupexternalfigures[location={local,default}]
\setuphanging[location=right]
\starttext
\startcolumnset[TwoColumns]
\dorecurse{3}{
\starthangaround{\externalfigure[cow][width=2cm]}
I want this cow to be in the lower right corner of the paragraph.
\input knuth
\stophangaround
}
\stopcolumnset
\stoptext
Versions: We're using mkii. But we get the same results for mkii and
mkiv on the example above.
Thanks,
Lars

[NTG-context] bug? gap appears in columnset
Hello,
We have a document where a gap occurs in a columnset under certain
conditions.
It seems to be a confluence of:
- 2 sections, each with 2-column columnsets
- \page[empty] between them
- the 2nd section has a tighter interline space
The problem is that on the first page of the second section, a two-line
gap appears where gridlines 50 and 51 are.
It may be a coincidence, but 50 is also the number of lines per page in
the first section. We've found that coincidence to be true even with
different page and font sizes.
Can anyone tell us a way to get rid of the gap? We've tried things like
\setupcolumnsetlines[columnsetbibliography][1][1][-1]
\setupcolumnsetlines[columnsetbibliography][1][2][-1]
with various values for the last parameter, but nothing helps.
Below is a small, self-contained sample.
Thanks for any help you can give.

Re: [NTG-context] bug? gap appears in columnset
It should also be mentioned that we need the second section to have a
tighter line spacing than the first, but despite the
\setupinterlinespace[line=9.3pt]
command, and despite the red grid lines being tighter, the text itself
seems to have the same interline spacing as in the first section. How do
we actually change the interline spacing?
Thanks again.

We do have pretty specialized layout requirements, including figures

I can't find \startmixedcolumns on the contextgarden wiki nor in the

rewrite of the old columns mechanism. I'm reluctant to entrust a big
production project to undocumented features, but at this point, if it
works, we'll probably go with it. I wonder if it's available in mkii as

Re: [NTG-context] bug? gap appears in columnset
Hans wrote,
Just wondering ... do you think that the first pages look ok?
Thanks for your response.
By look ok, are you referring to the closeness of the lines of text?
It does seem kind of close, but within acceptable limits, depending on
other constraints; however I'm not really the one to make aesthetic
decisions about the document. I'm just trying to implement what the
customer wants.
Also, the minimal example is stripped down to minimally exercise the
unexplained behavior, so it doesn't reflect the fact that in our actual
document, we reduce the font size in places where we reduce the
interlinespace. In that sense, maybe a less minimal example would serve
the purpose better. I'll work on that, now that I know the font size may
be an integral part of the problem.
You mess
with the interlinespace in a way that will make the outcome never look
okay.
I'd like to know more what that means, but I think it's elaborated on
below when you talk about baselineskip.
Also, columnsets assume that the interlinespace is sane.
Can you point me to documentation on the constraints that define what
kind of interlinespace is sane?
Also, given the goal that For using ConTeXt, no TeX programming skills
and no technical background are needed. Some basic knowledge of
typography and document design will enable you to use the full power of
ConTeXt (http://wiki.contextgarden.net/What_is_ConTeXt), does/could
ConTeXt issue an error when its assumptions are violated?
\setbox0\hbox{Tg}\the\htdp0,\the\baselineskip
gives
10.59601pt,9.3pt
so, any line that has a character with ascender and descender will
enforce a larger than 9.3pt distance + lineskip and mess up any
prediction cq. heuristics
I can't find any reference defining \htdp0, but I'm guessing it means
the height+depth (where depth means how far descenders extend below the
baseline) of the Tg box.
I'm also confused as to why you're adding 9.3pt + lineskip, when in my
limited understanding of TeX, I understood lineskip to be *part* of the
distance between baselines, rather than an additional distance. But
maybe that's not important to the main issue.
I'm trying to formulate a rule for knowing whether interlinespace is sane.
Is it that interlinespace needs to be more than or equal to the maximum
of (height + depth + lineskip) of any line in the text?
Thanks again for your help.

Re: [NTG-context] bug? gap appears in columnset
Regarding sane interlinespace,
Hans wrote,
ok, but then, an interlinespace is normally around 1.2 times the
bodyfontsize
OK. That's helpful.
But notice that in the following example, the interline space that
causes the problem is in the *first* section (where htdp is 12pt and
baselineskip is also 12pt!), while the gap shows up in the *second*
section, whose interlinespace is 2.8ex:
\def\printHtdp{\setbox0\hbox{()} \the\htdp0,\the\baselineskip}
\definecolumnset[columnset1][n=2]
\setupcolumnset[columnset1][distance=5mm,balance=yes]

\setupinterlinespace[line=2.8ex] %or use 11pt
\startcolumnset[columnset1]
\printHtdp
\dorecurse {10} { \input knuth }
\stopcolumnset
\stoptext
Since the problem can appear a ways after the cause, that makes it an
especially hard problem to track down, especially for someone who is
unaware of the nature of the problem. But even now that we're aware of
what the problem (hopefully) is, we've not been able to fix it in our
real-life document.
We sprinkled in many places the code to show htdp and baselineskip
(\printHtdp). E.g. in the early sections that would putatively cause the
problem, our htdp/baselineskip in 8.60252pt,10.5pt. That's a ratio of
more than 1.2. We have eliminated all the places we could find where the
htdp/baselineskip ratio was less than 1.2, even where there was no text.
But the gap persists.
We have a large and complex document, so there might conceivably be
places where a larger htdp than expected is hiding. Are there any tools
for automatically going through a document and reporting places where
not-sane interlinespace occurs?
Thanks,
Lars

Re: [NTG-context] bug? gap appears in columnset
Hans wrote, Columnsets are rather special and mostly meant for magazine like documents, where content can span columns, images are explicitly placed on the grid, etc. For that reason columnset soperate on a rather strict grid that gets setup based in the lineheight and although content can be larger, the grid dictates what happens. Balancing is semi automatic and nearly always demands some tweaks. In our use of columnsets, we do have content that can span columns (but we keep it outside of columnsets). We also have images within columns that are placed in the flow of text via hangarounds. We manually tweak our column lengths on each page (e.g. \setupcolumnsetlines[columnset10][1][1][42]), in order to avoid the worst of the widows and orphans. As you say, balancing requires manual tweaks too, but it's not that big a burden, since we're already doing \setupcolumnsetlines for many pages. Using columnsets for a large document that has to flow automatically is therefore debatable. Regular multi columns or in mkiv mixed-columns are a better choice then. We have tried to port our code to mkiv, but have so far found been unsuccessful. (But are trying again now, having found new success with TL2013 mkii.) Also, we've been unable to find any statement that mkiv is out of beta status. Moreover, much of the documentation still seems to be oriented toward mkii. So it's hard to justify much of a time investment in porting production work to mkiv yet. Can you comment on the official status of mkiv? Regarding mixed-columns: I understand it's a rewrite of the old columns model. My impression is that columns didn't support manual tweaking of column lengths (like \setupcolumnsetlines). Does mixed-columns support such a thing? That would be a critical question for us, as it wouldn't be an option for us to spend time porting to mkiv and using mixed-columns, if it doesn't allow us to tweak the height of each column on each page.

[NTG-context] question about linespace adjustment
Hello, I'm working through the reference manual trying to understand how things work in regard to fonts. I'll be submitting clarifications and elaborations to the manual in an attempt to help other non-experts to grasp the design of ConTeXt. There's a point that's confusing to me in section 5.5, Line spacing. On page 108 of the manual it says Linespacing alters when a new bodyfont is used or when linespacing is defined explicitly by \setupinterlinespace (which is explained later) But on the next page it says, When you make a font switch the linespacing is adapted when you give the command \setupinterlinespace without any setup parameters and also when you add the key reset, for example... So here's why I'm confused. When you change fonts, (a) does linespacing get changed automatically, or (b) do you have to say \setupinterlinespace? If (a), then why does the second quote above seem to say you need \setupinterlinespace to make it happen? If (b), then isn't the first quote above inaccurate? Is there a distinction being drawn here between when a new bodyfont is used and when you make a font switch, or are those just variant phrasings for what is intended to mean the same thing?

Contrast

Thanks for your help. You've left me to draw my own conclusions from
this example, so I'll say what I think this implies, and please correct
me if I'm wrong.
(Note to other non-TeXnichians: \endgraf is a TeX synonym for \par: end
of paragraph.)
I think the principle that you're trying to demonstrate is that the
answer to my last paragraph is yes: there is an important distinction
between making a font switch, e.g. \tfc, and using a new body font,
of which \switchtobodyfont is apparently an example.
Namely, that the latter causes the interlinespace to be automatically
adjusted, whereas the former doesn't unless you explicitly use
\setupinterlinespace.
Can you explain how/why the two ways of increasing the font size should
have such different effects? (I have read section 5.8 and 5.9 about
selecting bodyfonts and interlinespace but still don't get it.)
\tfc is described as a font selector command (5.3.2). It seems to me
that both \tfc and \switchtobodyfont[20pt] simply attempt to switch to a
different size of whatever bodyfont is currently in effect. But there
must be something I'm missing. (Or else it's just an arbitrary
distinction, but that seems unlikely.)

You can look into
font-pre.mkiv
OK. I'm looking at it,
http://repo.or.cz/w/context.git/blob/HEAD:/tex/context/base/font-pre.mkiv
Is there anything in particular you had in mind that I can learn from it?
I found some aliases, e.g. \smaller, which are handy to know. But I
don't know how much I can rely on the undocumented ones to continue to
do what they do now.
\tfc augment the fontsize of a factor of 1.728
It's relative to the default fount size not to the current fontsize:
{\tfc foo {\tfc foo}} both foo have the same size
Thank you, this is an important nugget that I didn't understand when
reading the documentation. \setsmallbodyfont and \setbigbodyfont, in
contrast, change the font size relative to the current size.
But interlinespace is not modified, so we need to reset

OK: \input knuth\blank{\tfx\setupinterlinespace OK: \input knuth\blank
\tfc\setupinterlinespace OK: \input knuth\blank}
\stoptext
Ok. This confirms what Aditya said, and what the manual says: that you
have to use \setupinterlinespace after \tfx or \tfc if you want the
interlinespace to be adjusted.
But I would really like to understand the categories involved here.
So we have one category of font size selector commands, which includes
\setsmallbodyfont and \setbigbodyfont, that cause interlinespace to be
adjusted automatically.
Then we have another category, including \tfc, \tfx, \ita, and others,
that do not cause interlinespace to be adjusted.
What is the rhyme or reason behind these categories? And that would help
me know, which other commands belong to which category? E.g. would
\serif cause interlinespace to be adjusted? An experiment would reveal
the answer, at least in the circumstances that I think of testing, but
I'd like to understand the conceptual model.
Maybe the concept is that the first category affects the body font
(and therefore interacts with the properties of the body font
environment), and the second category only affects the font (and I'm
still not clear on how the body font differs from the current font).
Thanks for your help,

I don't know how this answers the above question. Can anybody explain?
Clearly you're drawing a comparison between \switchtobodyfont[14pt] and
\tfc.
I've run the sample, and I see that, as in other samples earlier in this
thread, \switchtobodyfont causes the interlinespace to be adjusted
accordingly, and \tfc doesn't.
Is that intended to be an answer to 'how the body font differs from
the current font'? And is the answer that the bodyfont is a conglomerate
of more properties than just the font, including interlinespace?

Re: [NTG-context] question about linespace adjustment
Wolfgang, thanks for your response. On 9/25/2013 5:02 PM, Wolfgang Schuster wrote: You can’t expect from \tfa etc. to change the interlinespace because these commands can be used in your paragraphs to change the size of certain words only and in this case you don’t want a forced change of the interlinespace. Well... \switchtobodyfont[20pt] can also be used in paragraphs to change the size of just a few words. But the above suggests that \switchtobodyfont shouldn't be used for that purpose, and commands like \tfc should? To adapt the interlinespace when you now use \tfa etc. you have to add \setupinterlinespace to your code (arguments aren’t needed) to tell context to recalculate it. Thank you. What I'm trying to learn now is *why* that's true. Or more precisely, where is the boundary between the font-changing commands that automatically adjust interlinespace, and those commands that don't? and what is the conceptual model that motivates the boundary, and helps users remember and predict where the boundary lies? What I think I'm hearing is that \switchtobodyfont is intended for changes of longer duration, say, at least a paragraph. Whereas \tfa and so on are intended for brief changes, to set off a phrase, for example. As an example of where's the boundary, experimentation shows that \setsmallbodyfont is in the same category as \switchtobodyfont: it automatically affects the interlinespace. Nevertheless I can't find anywhere in the manual or on the wiki that tells me that \setsmallbodyfont differs from \tx in this way (let alone *why* it differs). Maybe I should expect that any command that has bodyfont in its name is intended for long-term changes, and other commands aren't? Sorry if I'm being slow on the uptake. Documentation like http://wiki.contextgarden.net/Command/switchtobodyfont just doesn't seem to explain this difference in intention. Thanks again. I do hope to use this experience to contribute clarifications to the manual. I've already done that some on the wiki (hoping that if I get it wrong, someone will correct my mistakes!)

So the technical barrier to participation is low. I would question the perception that the technical barrier to participation on Github is low. Not long ago I tried to submit a patch to a project on Github, improving documentation and adding features. It took several hours (distributed over a couple of weeks) to learn how to do all that was required. It was *not* automatic. It strongly discouraged me from making more contributions to that project. Maybe some major things have changed on Github since then. In any case, I have no doubt that once you know the system, and have the infrastructure set up, it's easy to participate. And I'm not saying that SVN makes it easy for non-SVN users to participate. All I'm saying is that for non-Git users, the technical barrier to participation was substantial, last time I tried it.

Well... \switchtobodyfont[20pt] can also be used in paragraphs to change
the size of just a few words.
But the above suggests that \switchtobodyfont shouldn't be used for that
purpose, and commands like \tfc should?
You can use \switchtobodyfont to change the size for certain parts of a text
but it’s best to keep this to a minimum because \tfa etc. are a lot faster.
The reason why you don’t need \setupinterlinespace when you use
\switchtobodyfont is that \setupinterlinespace is already called by
\switchtobodyfont.
OK, good to know.
Another thing which shouldn’t be forgotten is that \switchtobodyfont
controls and changes the sizes for \tfa etc.
Can you elaborate on that?
A few days ago, Luigi wrote,
\tfc augment the fontsize of a factor of 1.728
It's relative to the default font size not to the current fontsize
So when he says relative to the default font size, does that mean the
same thing as relative to the current body font size? I think so. The
following example shows that the function of \tfc is relative to the
size set by \switchtobodyfont:
{\tfc tfc \tfc tfc}
{\switchtobodyfont[20pt] 20pt \tfc tfc}
{\switchtobodyfont[6pt] 6pt \tfc tfc}
Here the text after \tfc appears in three different sizes, proportional
to (and larger than) the \switchtobodyfont setting in effect. However,
the first line shows us that \tfc is *not* affected by previous effects
of \tfc. So as Luigi said, there is a distinction between the current
font size (which is affected by \tfc), and the default font size -- or
maybe it should be described as the current body font size -- which is
not affected by \tfc.
Is that correct?
So does \tfc mean set the current font size to be three steps up from
the current body font size?
Thanks. I'm contributing clarifications into the manual as I come to
understand how things are designed to work.

Anything that changes the bodyfont, such as \switchtobodyfont, also affects the linespacing. Just changing the effective font does not affect the linespacing.

[NTG-context] can't find file `core-swd'
Hello,
I've just been trying to install context on Ubuntu 8.10.
Today I went to http://minimals.contextgarden.net/setup/
and followed the instructions:
On unix (linux, mac, freebsd, sun, ...) run:
mkdir context cd context
rsync -ptv rsync://contextgarden.net/minimals/setup/first-setup.sh .
./first-setup.sh
The first-setup script initially failed because I did not have ruby
installed. So I installed ruby and then ran it again.
It cranked away for awhile, then ended up with the error:
! I can't find file `core-swd'.
to be read again
\relax
l.228 \loadmkiifile{core-swd}
The preceding output was:
systeem : markering subsubsubsubonderwerpnummer gedefinieerd
[subsubsubsubonderwerpnummer]
)
However, when I do a search, I see that there is a file core-swd.mkii.
Its path is context/tex/texmf-context/tex/context/base
(I kid you not -- tex and context each show up three times in the path!)
Can anybody suggest how to fix the problem?
Thanks,
Lars

Just to clarify, since I wasn't explicit: there is no core-swd.tex file
in the context/base folder.
Googling core-swd context gives results that indicate there used to be
a core-swd.tex file there. I could use the google cached copy, although
I suppose there was some reason why it was removed?
After using the google cached copy, and rerunning the first-setup
script, the script ends without obvious errors:
TeXExec | runtime: 14.383196
make | done
state | saved
Can anyone confirm that using the cached core-swd.tex indeed solved the
problem, rather than merely masking it?
Maybe core-swd.tex was rightfully removed, and the correct fix would be
to remove the reference to it in the other file?

Lars

I got basically the same as Alan Stone:
/home/ethnologue/context/tex/texmf-context/tex/context/base/core-
swd.mkii
It's Hans fault, he loads core-swd in context.mkii with the command
\loadmkiifile but the command expects .tex as file extension, you
could either rename core-swd.mkii to core-swd.tex or you change
the line \loadmkiifile{core-swd} to \loadmarkfile{core-swd} or
\loadmkiifile{core-swd.mkii}.
Wolfgang
OK, thanks.

[NTG-context] modifying URL wrapping rules
Hello,
I would like to modify the rules for wrapping URLs (aka hyphenating
URLs, but generally without inserting hyphens) to conform more closely
to the Chicago Manual of Style, 15th ed. I've read on this list that the
code for doing this is defined in the \hypthenatedurl
There are several files with the same name, in
contextminimal\texmf-context\tex\context\base\:
lang-url.mkii
lang-url.mkiv
lang-url.lua
lang-url.tex
From what I can tell, the .tex file loads one of the other three:
\loadmarkfile{lang-url}
I'm not sure which one it loads -- the lua, mkii, or mkiv.
All three seem to have the rules for url hyphenation encoded in them.
Is it a matter of which engine I'm using, e.g. luatex?
Our project has a requirement of using Xetex, so I have to stick with
that. Does that mean lang-url doesn't work at all?
We also have users using ConTeXt Minimal as well as ConTeXt from the
TeXLive 2008 distribution.
I want to do things in a way that will work in both. I would be happy to
put in some extra effort to make the result generally available to
others who want to follow the Chicago style for wrapping long URLs.
Thanks for any hints...
Lars

\loadmarkfile loads either lang-url.mkii or lang-url.mkiv, depending
on the ConTeXt version you're running (MkII / MkIV). In Mark IV, the
Lua code is then put in lang-url.lua, which is input by lang-url.mkiv
(you can see \registerctxluafile{lang-url}{1.001} near the beginning
of the latter). This architecture enables you to reuse the Lua code in
completely different environments (for example, in a pure Lua script).
Our project has a requirement of using Xetex, so I have to stick with
that. Does that mean lang-url doesn't work at all?
ConTeXt on XeTeX is considered Mark II as far as the mark business
goes (it doesn't know about Lua), so you have access to the exact same
code as with pdfTeX; in this case, lang-url.mkii will be loaded.
Thanks for the explanation... this is helpful.
So it sounds like I should definitely modify the lang-url.mkii file.
But if
you know that all your users will be using XeTeX, you don't really need
to worry about the \loadmarkfile mechanism; it is there to accommodate
different engines.
OK... but I'm not sure what I would do differently if I'm not worrying
about the \loadmarkfile mechanism... Still modify the lang-url.mkii file?
Given that I'm willing to put in a little extra effort to make the
result available to a wider set of users, should I still modify
lang-url.mkii?
We also have users using ConTeXt Minimal as well as ConTeXt from the
TeXLive 2008 distribution.
The particular distribution one uses shouldn't be a problem at all for
implementing hyphenation rules.
Good to know, thanks.
I want to do things in a way that will work in both. I would be happy to
put in some extra effort to make the result generally available to
others who want to follow the Chicago style for wrapping long URLs.
This will certainly be most appreciated.
I will probably need more help in order to know how to do this. Once
I've finished doing it for us, in .mkii, I'll ask again on this list.
Thanks again,
Lars

OK, I've taken a stab at it. Here is the main code now in the modified
lang-url.mkii. For brevity in this email I've just omitted the lines
that I actually commented out in the file, namely characters that
Chicago style does not say you can line-break URLs on.
\def\sethyphenatedurlnormal#1{\expandafter\chardef\csname url @
#1\endcsname\zerocount}
\def\sethyphenatedurlbefore#1{\expandafter\chardef\csname url @
#1\endcsname\plusone }
\def\sethyphenatedurlafter #1{\expandafter\chardef\csname url @
#1\endcsname\plustwo }
% Chicago manual of style rules:
% Break URLs after: / or // (I don't know how to implement // so will be
content with / for now.
% To do: prevent breaking in middle of double slash //.)
% Break URLs before: ~ . , - _ ? # %
% Break URLs before or after: = (I don't know how to implement 'before
or after' so will
% be content with breaking 'before' these characters for now).
\sethyphenatedurlbefore \letterhash
\sethyphenatedurlbefore \letterpercent
\sethyphenatedurlbefore \letterampersand
\sethyphenatedurlbefore ,
\sethyphenatedurlbefore -
\sethyphenatedurlbefore .
\sethyphenatedurlbefore =
\sethyphenatedurlbefore ?
\sethyphenatedurlbefore _
\sethyphenatedurlbefore \lettertilde
\sethyphenatedurlafter / % was \sethyphenatedurlbefore /
However, I have a few unsolved problems here.
1) I don't see a way, with the '\sethyphenatedurlbefore' or 'after'
mechanism, to tell it not to break a URL between two slashes, as in
http://;. At first I thought that since our text only had a few URLs,
we'd likely never care. But ... you guessed it. One URL got broken
between the slashes: http:/
/www.sil.org/...
So I tried using the base tex hyphenation mechanism to inhibit breaking
there: I changed the document from
\hyphenatedurl{http://www.sil.org/...}
to
\hyphenatedurl{\hyphenation{http://}www.sil.org/...}
but that gave a stack overflow.
Then I tried
\hyphenation{http://}\hyphenatedurl{www.sil.org/...}
but got this error:
! Not a letter.
inserted text http:
//
\hyphenation ...malhyphenation {\the \scratchtoks
}\endgroup
argument ... Linguistics. \hyphenation {http://}
\hyphenatedurl
{www.sil.or...
\BE #1-\startmainexdent {#1
}\stopmainexdent
l.317 ...l.org/silesr/abstract.asp?ref=2007-015}.}
I'm kind of shooting in the dark there, so maybe somebody who knows TeX
can help me out.
2) Even though I have \sethyphenatedurlafter / instead of
\sethyphenatedurlbefore /, there are four cases where a URL is broken
before a slash, e.g.:
http://www.sil.org/.../009
/YAMBASSA.html.
and no cases where a URL is broken after a slash (except when it's also
before a slash -- see 1).
I wonder if my modifications are actually taking effect?
Do I need to compile the changes to the .mkii file or something? I tried
texexec.bat --make --all, but that didn't seem to change the outcome.
3) Conversely, even though I have \sethyphenatedurlbefore - and not
\sethyphenatedurlafter -, there is a case where a URL is broken after
a hyphen (a hyphen that was already present in the URL):
http://www/Niger-
Congo/...
and no case where a URL is broken before a hyphen.
Note that the \sethyphenatedurlbefore - setting is unchanged from the
original lang-url.mkii, so this is not an issue of needing to recompile.
Maybe the general tex hyphenation mechanism is operating here, in spite
of the URL breaking settings. How do I override that (only for the URL)?
4) In one case, a URL is broken over the end of a column. That's ok, but
it would be nice to be able to strongly discourage that from happening
at the end of a page. I'm told that's a difficult problem to solve. It's
not mandatory for us at this point but if anyone has a solution I'd like
to hear about it.
Thanks,
Lars

cleaner than the lefthyphenmin hackery .,..
{\hbox{http://}\hyphenatedurl{www.sil.org/...
Thank you!
in context mkiv i can provide a hyphenater based on the url syntax
(after all, mkiv already has an analyser for urls)
That would be great, but as I understand it, using mkiv would require us
to move to a beta version of ConTeXt... and we're right at the end (we
hope!) of a production cycle, where moving to any new version (whether
beta or not) could cost us a lot of time if any behavior changes.
So while I would be glad to see a hyphenator based on URL syntax, I
don't think a mkiv version won't help us this time.

Maybe it would help if someone could explain to me what 'normal' means
in lang-url.mkii:
\def\dohyphenatedurlnormal#1{\char#1\relax}%
\def\dohyphenatedurlafter
#1{\char#1\discretionary{}{\hyphenatedurlseparator}{}}%
\def\dohyphenatedurlbefore#1{\discretionary{\hyphenatedurlseparator}{}{}\char#1\relax}%

\def\sethyphenatedurlnormal#1{\expandafter\chardef\csname url @

#1\endcsname\plusone }
\def\sethyphenatedurlafter #1{\expandafter\chardef\csname url @
#1\endcsname\plustwo }
It looks like 'normal' means don't put a discretionary
hyphenatedurlseparator before/after the character. Which would mean
either (a) the url cannot be separated there (unless an adjacent
character has hyphenatedurlbefore/after specified on it); or (b) the url
will follow the same hyphenation rules as normal text (no special
url-related rules). Can anyone tell me which it is? The definition of
hyphenatedurl is:
\unexpanded \def\hyphenatedurl#1%
{\dontleavehmode
\begingroup
\the\everyhyphenatedurl
\edef\ascii{#1}%
\expanded{\handletokens{\detokenize\expandafter{\ascii}}}\with\dohyphenatedurl
\endgroup}
and the definition of \dontleavehmode is in syst-ext.tex with some comments:
%D \macros
%D {dontleavehmode}
%D
%D Sometimes when we enter a paragraph with some command, the
%D first token gets the whole first line. We can prevent this
%D by saying:
%D
%D \starttyping
%D \dontleavehmode
%D \stoptyping
...
\unexpanded \def\dontleavehmode
{\ifhmode\else \ifmmode\else
\setbox\@@dlhbox\hbox{\mathsurround\zeropoint\everymath\emptytoks$
$}\unhbox\@@dlhbox
\fi \fi}
...
%D But, if you run a recent version of \TEX, we can use the new
%D primitive:
\ifx\normalquitvmode\undefined \else \let\dontleavehmode\normalquitvmode \fi
I am running Xetex, FWIW.
This is XeTeX, Version 3.1415926-2.2-0.999.6 (Web2C 7.5.7)
The above makes me think that dontleavehmode should prevent any
'hyphenation' except for the types explicitly allowed in lang-url.mkii
via \sethyphenatedurlafter/before/normal.
Yet that isn't happening... it's breaking before slash instead of after,
and after hyphen instead of before.
I wondered briefly whether I had misinterpreted (swapped) the semantics
of \sethyphenatedurlafter and \sethyphenatedurlbefore. But no,
\sethyphenatedurlbefore . is working as expected: URLs break before a
period. So I'm just puzzled.
Thanks for any help...

OK, I did that. Behavior with respect to the two outstanding problems
(breaking after hyphen and before slash) has not changed.
But it's good to know that it's not due to some dependencies not being
updated.
however, i strongly advise you to put such patches or tuning in your
document style because otherwise you loose them when you update
Understood. A colleague tells me that if I put the
\sethyphenatedurlbefore/after settings in the .tex document they will
override the settings in lang-url.mkii, which is very good news.
So if lang-url.mkii says
\sethyphenatedurlbefore \letterbar
I can comment that line out in lang-url.mkii; but if I don't want to
modify lang-url.mkii, can I accomplish the same thing by putting
\sethyphenatedurlnormal \letterbar
in my .tex file?
\ifx\normalquitvmode\undefined \else \let\dontleavehmode\normalquitvmode \fi
I am running Xetex, FWIW.
This is XeTeX, Version 3.1415926-2.2-0.999.6 (Web2C 7.5.7)
The above makes me think that dontleavehmode should prevent any

just leave dontleavehmode untouched; it's definition adapts itself to
the engine
i leave it to others to react on the rest of your mail (some users have
been tuning the mechanism too)
I would be very glad to hear from said users who have had any success.
I'm emailing Steffen and Aditya now.
Actually, just now looking at lang-url.tex I see the comments
%D For those who want to put full \URL's in a text, we offer
%D
%D \startbuffer
%D
\hyphenatedurl{http://optimist.optimist/optimist/optimist.optimist#optimist}
%D \stopbuffer
%D
%D \typebuffer
which makes me wonder if I need to put the
\startbuffer,\stopbuffer,\typebuffer commands in my tex code. But I
think maybe it's markup for generating documentation.
If so, I wonder why I can't find such generated documentation on
\hyphenatedurl.

OK... I have a working workaround... close your eyes, because it's ugly.
I just put \hbox{} around the sections that we don't want broken, and
\discretionary{}{}{} in the places we will allow a break:
\hbox{http://}\discretionary{}{}{}\hbox{www}\discretionary{}{}{}\hbox{.sil}\discretionary{}{}{}\hbox{.org/}\discretionary{}{}{}\hbox{silesr/}...
One of our URLs goes from 89 to 391 characters! :-p
Maybe posting this awful kluge to the list will motivate someone who
knows TeX better to post a more elegant solution. :-)
Ugly as it is, it does allow me to control exactly where I want to allow
a break and where I don't. So I'll go with that for now, in order to
meet our deadline.
I'm sure someone could write a TeX macro to do the above algorithmically
instead of brute-force specifying every possible break point explicitly.
But that's what \hyphenatedurl is supposed to be, and it doesn't seem to
be working for me.

Thanks, this is great.
Looks like, as in improvement over \hyphenatedurl, it allows you to
specify that you can break before a character, after, or both.
I think I can even see how to use it in a document...
though, would I have to undo the initial \catcode commands after the
\egroup?
Also, I don't see a way to prevent breaking between two slashes...
unless you treat them as part of a separate hbox:
\hbox{http://}\ForMojcaWhoLikesHacks{www.sil.org/silesr/}
which is not a big problem.

[NTG-context] difference between TeX behavior and ConTeXt
Hello,
I've been reading through the TeXbook to solidify the foundations for
TeX programming. In an exercise on roman and italic text, ConTeXt seems
to behave differently from what the book specifies (Plain TEX) at a
fairly fundamental level.
Exercise 4.1 says, Explain how to typeset a roman word in the midst of
an italicized sentence.
I wrote, and the solution in the appendix says,
{\it Explain how to typeset a\/ {\rm roman} word
in the midst of an italicized sentence.}
But when I typeset this using texexec, the word roman appears in
italic, just like the rest of the sentence.
I tried this on both Windows XP and Ubuntu Linux, with both PDFTex and
Xetex engines. On Windows I'm using ConTeXt minimal, and on Linux I'm
using ConTeXt from the TeXLive 2008 CD. The result is the same in all
cases: all the text is italicized.
Does this difference in behavior represent a known feature of ConTeXt?
If so, is it a difference in the defined behavior of \rm?
When I put \show\rm in the .tex file to display the definition of the
\rm macro, and run texexec, I get:
\rm=\protected macro:
-\setcurrentfontstyle {rm}.
l.7 \show\rm
By contrast, according to
http://webpages.charter.net/davidlha/.trm/trmi.html, Plain TeX defines
\rm to be `\fam=0 \tenrm'.
So clearly the definition of the \rm macro is different in ConTeXt than
it is in Plain TeX.
I could understand ConTeXt possibly changing the details of \rm's
definition, e.g. a change in default font family; but it would really be
surprising to find that the logic of \rm's behavior has been changed.
Please help me understand if this is a bug or if there is a design
principle of ConTeXt that I should be aware of...
Thanks,
Lars

P.S. The same TeX reference reports,
This switch plus the assignments made by Plain TeX are what makes
`${\rm text }$' typeset `text' in roman instead of in italics [154].
where [154] refers to the page number in the TeXbook.
The latter says The control sequence \rm is an abbreviation for '\fam=0
\tenrm'; thus, \rm causes \fam to become zero, and it makes \tenrm the
current font. In horizontal mode, the \fam value is irrelevant and the
current font governs the typesetting of letters; ... [stuff about math
mode, which doesn't seem to apply to this situation].
FWIW.

Thanks for the explanation.
I hope that when the manual is finished it will make this clearer.
Currently, the draft chapter says
As will be explained later, the command \rm is used to switch to a
roman/serif/regular style
which does not seem to be happening.
I think it is due to a difference in terminology between (plain) TeX and
ConTeXt.
Knuth uses roman to mean with serifs and not slanted
Interesting.
As a newbie to typesetting, reading the TeXbook, I certainly wondered
which axes Knuth meant 'roman' to refer to... he simply describes it
as 'normal roman' and gives a visual example. So far, all I'd gathered
was that it meant not italic.
Now that you brought up serifs, I read further in the chapter where
Knuth introduces \rm (ch. 4). He eventually makes clear that he does not
contrast roman with sans-serif (nor with slanted!), because he mentions
both slanted roman (p. 13) and the approved use of \rm to be temporarily
defined to mean a sans-serif type (p. 15). Apparently the only thing
roman is contrasted with in Knuth's book is italic (i.e. the modified
glyph style of an italic font, regardless of the slant).
Out of curiosity, I looked up 'roman' with regard to typography on
wikipedia. On the disambiguation page for Roman it says Roman type, an
upright typeface style, contrasted to italic. But on the Roman_type
page it lists both not-italic and with-serif as (separate) senses of
roman. Thanks for the tip.
Regardless of the terminology used, though, what is objectively clear is
that \rm has different effects on font settings in ConTeXt than in Plain
TeX. The TeXbook makes clear by example, if not by statement, that one
of the effects of '\rm' must be to make text non-italicized (also
non-slanted).
If it's designed not to do that in ConTeXt -- i.e. the ConTeXt designers
decided to change the semantics of one of the basic control sequences in
TeX, rather than merely providing a different one with new semantics --
you would think one would want that to be prominently documented. (Maybe
some flashing orange lights? :-)
Whereas \rm is not found at all in the command reference at
http://texshow.contextgarden.net/
while ConTeXt
uses it to mean just not sans serif.
I wonder if the command sequence \serif was already taken?
That would certainly be less ambiguous and confusing...
So something like
aardvark {\it aardvark {\rm aardvark}}
is really doing something like:
- Set aardvark in the default face (which is probably an unslanted serif)
- Switch to the italic flavor of the default face, which here means a
traditional italic
- While in the italic flavor, switch to a roman base. But we already
had a roman base so this doesn't change anything: we are still slanted
because of the enclosing \it.
Roman and italic are on different axes and can be changed independently.
It makes sense for italicness and serifity to be independently
changeable.
What's discouraging to me as a entrant to the whole TeX world (but an
experienced programmer) is the (apparently undocumented) redefinition of
a well-established control sequence that used to mean non-italic to
mean something different (maybe serif -- I still don't know for sure).
If I were choosing a TeX macro package at this point, I would definitely
look for one that kept semantics of basic TeX command sequences
consistent with the intent expressed in the TeXbook... to avoid package
lock-in, as well as to make the learning curve easier and to be able to
use the resources of the whole TeX community.
That being said, I appreciate the design goals of ConTeXt, including the
desire to have independent controls for +/- italic, +/- serif, etc. I'm
also amazed at the energy that Hans still devotes to answering questions
on this mailing list, 18 years after ConTeXt was written! That's dedication.
Sorry if the above sounds too negative. After all, the TeXbook itself
does not make the semantics of \rm obvious.
However, once you dig deep enough it becomes clear that \rm does mean
switch to a non-italic typeface in Plain TeX.
However, things are different if we start off in a sans serif face, like
\ss aardvark {\it aardvark {\rm aardvark}}
Now the \it still gives slanted text, but since the base is sans serif
we don't get the traditional italic appearance that corresponds to a
roman base. The nested \rm now does that.
(Note: my terminology is all wrong. Base and flavor aren't the
right terms at all, but I cannot remember the correct terms right now.
I would be grateful is someone could correct me.)
Cheers,
Rory
Lars

Hi, and welcome to the TeX world;). Me not being an experienced programmer, but (some kind) of more or less experienced TeX user, I'd add the following. I appreciate your time and the explanations, from an experienced TeX user. (To all) please pardon the frustration apparent in my previous email, from a TeX and especially ConTeXt newbie. It is probably true that plain TeX is weird and incomplete in a sense. What \rm means in plain TeX is: switch to upright, serif font in 10pt size. This is good to know. However what I'm getting at is not just its concrete definition (implementation) in Plain TeX, but its general intent. The reason I ask that question is this: Knuth makes clear in TeXbook ch. 4 that \rm and other macros are intended to be redefined according to the needs of the book section. Therefore \rm is not intended to remain defined always specifically as switch to upright, serif font in 10pt size. But it is *not* intended that \rm be defined to mean reduce the left margin to the dimension provided by the following argument, or even switch to italic, serif font in 10pt size. Sure you could define \rm to mean anything, but your end users would string you up. Somewhere between those extremes is an intended consistency of meaning for \rm. If it were not so, macro packages would be gibberish, intelligible to the executing processor but intractable for humans. My contention is that the intended invariant of \rm semantics, communicated in TeXbook (e.g. exercise 4.2 and the bottom of p. 15), is that of not italic. [helpful orientation on the major macro packages snipped] (and level of frustration), sometimes with LaTeX having more wtf per minute I had not heard of that metric before. :-) That's right. I would add one more point: if everyone called the software of ConTeXt quality beta, then Windows would be pre-alpha and a typical GNU/Linux probably something between alpha and beta. Except perhaps the documentation. I have yet to find a reference that clearly describes what \rm is to do in ConTeXt. One responder pointed to http://www.pragma-ade.com/general/manuals/cont-eni.pdf. The closest thing to a definition of \rm there that I could find is on p. 111: The command \rm is used to switch to a roman/serif/regular style,... These three terms are not explicitly defined; they are given as names of styles in an illustrative table above. One may apparently assume that the meaning serif style here actually is intended to mean that the typeface has serifs (not a trivial assumption: see 'regular'). However the examples of serif/regular/roman in the illustrative table are also all non-italic, and the word regular in typography usually (as far as I can tell... please enlighten) means upright in contrast to italic. Yet apparently \rm does not switch to regular (if that means or includes upright) in ConTeXt. Sorry if the above sounds too negative. After all, the TeXbook itself does not make the semantics of \rm obvious. Well, it does, but _not_ in the context of changing sizes/styles/etc... Again, I think we're talking about two different things: the original macro definition in Plain TeX, vs. the communicated intended invariant meaning over redefinitions of \rm in various formats (Knuth's term which I take to mean macro packages or something like that). However, once you dig deep enough it becomes clear that \rm does mean switch to a non-italic typeface in Plain TeX. I'll stress it again: no. In plain TeX, it means switch to cmr10 at 10pt, full stop. See previous comment. But even in plain TeX, switch to cmr10 at 10pt *does* include switching to a non-italic typeface, which is what I meant here. I didn't mean that in plain TeX \rm means *only* switch to a non-italic typeface. Sorry that wasn't clear. And the jolt here with ConTeXt is that the meaning of \rm no longer includes switch to a non-italic typeface, and that this change is not clearly documented.

The basic idea is that the style rm switches to the font set used for the main portion of the text. ss is the style for supporting texts, like section heads and headers/footers. tt is useful for fixed-width text, (this gets it own special group because it is very often needed in manuals). hw, and cg are variations for different forms of supporting texts, these are rarely used.

I think it would be worthwhile to explain that in the manual you are writing (if it doesn't already... sorry, I'm on a tight deadline now and can't recheck!)... that the style rm switches to the font set used for the main portion of the text, which typically is a serif font.

[NTG-context] widow/orphan control in columns?
Hello,
We have a document with a 2-column layout where we have section headers
that keep ending up at the bottom of columns.
E.g.
\startsectionheading{2. Foo bar baz}\stopsectionheading
where \startsectionheading is defined by:
\definestartstop
[sectionheading]
[before={ \startalignment[middle]},
after={\stopalignment \bigskip},
style={\switchtobodyfont[...,...]}]
In order to make sure this section heading gets followed by a line or
two of actual text, I saw on web pages [1] and [2] that you can use
\testpage[n] to check whether there is room for n more lines, and if
not, to produce a page break. I checked the manual [3] and command
reference [4] but couldn't find information about \testpage.
Is there a corresponding command to conditionally produce a column break?
Thanks,
Lars

[NTG-context] how to get thick and thin borders working in tables (ConTeXt)
Hello, We are using ConTeXt (with XeTeX engine) to typeset some tables that have borders (rules) between cells. In the previous edition of the book (which was not done in TeX), some of the lines between table cells were double, others single. This was done to show grouping of columns and rows. We have been told that in TeX, or at least in ConTeXt, you can't do double rules (we'd be happy to be corrected on that point), so we have been trying to use thick and thin lines to show grouping. Thick or thin lines work fine if applied to whole tables or whole cells, but when there are cells with thick rules on some sides and thin rules on other sides, it gets confused. For example, we tried (a) \setupTABLE[c][4][leftframe=on,rulethickness=0.5mm] to set the left border of the fourth column to be thick. This worked. But then if we use (b) \setupTABLE[c][4][rightframe=on,rulethickness=0.25mm] to set the right border of the same column to be thin, it overrides the thickness of both left and right borders, so setting (a) is lost. In other words, we can't seem to get a given cell to have a thick border on one side and a thin border on the other side. (Well, we could fake it in some cases by setting rulethickness for an adjacent cell, but that adjacent cell would then have to have thick borders on all sides.) Does anybody know if it's possible to do this in ConTeXt? or in TeX? Thanks for any ideas, Lars P.S. Incidentally, if you set the bottom border of row 1 and the top border of row 2 each to be thick, the result is additive: you get a doubly-thick border. ___ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / http://www.ntg.nl/mailman/listinfo/ntg-context webpage : http://www.pragma-ade.nl / http://tex.aanhet.net archive : https://foundry.supelec.fr/projects/contextrev/ wiki : http://contextgarden.net ___

This was mainly experimental, as I don't fully understand the model.
(I looked up some Metapost references but couldn't find a definition of
enlarged.) But it seems to work: the double lines between two cells
overlap exactly, so you get a consistent look.

setbounds currentpicture to OverlayBox ;
\stopuseMPgraphic
Now the graphic has double line on the left and a single line elsewhere.
However, the lines are thicker than in the previous one... about twice
as thick, too heavy for our requirements. And I can't tell why. This is
true on all four sides.
See http://www.huttar.net/lars-kathy/tmp/test-mp-tableframe.pdf, second
table.
Also, on the side that has double lines, the double lines don't go all
the way to the top and bottom (see same pdf, second table), so that the
double line is not continuous across multiple rows.
Any suggestions?
The above graphic is used as follows...

This fixes the problems I mentioned in my previous email. Thanks again
for that!
Unfortunately, when I generalize it, it takes us back to producing
triple borders between adjacent cells. I think this is inevitable when
overlaying a double frame (for certain sides) on top of a single frame
for all sides, because a double side overlaid on a single side cannot be
centered (or else the single line shows through separately from the
double line).
So my fix... which I'm posting here in hopes that someone may refine it,
and for the benefit of others who may attempt similar things... is to
center the double frames between the cells and avoid overlaying a double
frame side over a single frame side.
We center borders between the cells by using enlarged values -0.2 +/-
k, i.e. center around -0.2. I'm not sure why -0.2 works better than
zero, but it does... Doing this makes coincident border lines from
adjacent cells look like ordinary single lines instead of being extra
thick. We settled on k = 0.6 to get the desired distance between our
double lines. Incidentally, I wish I knew how to put -0.2, 0.2-k, and
-0.2+k into variables or something so that they could all be changed in
one place, instead of hard-coded in many places. Maybe somebody can help
me there.
A cost of this single-overlay-per-cell approach is that we have to
specify individually the 16 possible overlays (combinations of single
and double edges) for any possible cell. But that's not too bad, as we
only have to define them once. (In practice, we also had to define a
couple of special cases where we needed some cells with open edges for a
faked rowspan. We haven't completely got those working yet.)
An unexpected and potentially large benefit of this approach is that for
each cell, we only generate one MPgraphic (apparently because we only
use one overlay per cell), which should make the TeX run much faster,
and avoid running over the maxnumMPgraphics limit. With the
multiple-overlay-per-cell approach, we ended up using about 13,000
MPgraphics for our document, far beyond the default limit of 4000, and
taking 15 minutes to run compared to 37 seconds for a similar document
without the tables.
Here is our working system... hope it's helpful to somebody:
define MPgraphics for double-ruled tables

Use the 'nomprun' switch for texexec
texexec --nomprun --xtx file
ConTeXt collects now all graphics and process them after the TeX run.
Hmm... we tried this, but it doesn't seem to make any obvious difference.
Is this supposed to give a speed improvement? or get around the
maxnumMPgraphics limit?
Thanks again for your help.

[NTG-context] distributed / parallel TeX?
Hello, We've been using TeX to typeset a 1200-page book, and at that size, the time it takes to run becomes a big issue (especially with multiple passes... about 8 on average). It takes us anywhere from 80 minutes on our fastest machine, to 9 hours on our slowest laptop. So the question comes up, can TeX runs take advantage of parallelized or distributed processing? As many in the computer industries are aware, processor speed (clock rate) has plateaued; it is not going to continue rising at the rate it had been. Hence the common move to dual-core, quad-core, etc. machines. But applications in general cannot take advantage of multiple cores to speed their work unless they are architected to take advantage of them. We googled around a bit but were surprised not to find any real references to efforts at running TeX in parallel or on distributed networks or clusters. Wouldn't this be something that a lot of people would find useful? Or does everyone only use TeX for typesetting short papers? Sure, you can use manual tricks to speed up TeX processing. You can comment out sections of a document, or select them via modes. But then you have to remember where you did the commenting out, so you can reverse it. And you have no guarantees as to whether the inclusion/exclusion of section B will affect the layout of section C or not. Wouldn't it be nice if TeX (or a TeX wrapper, or macro package, or typesetting system) could take care of this for you? What if you had a language -- or a few extensions to existing languages -- to give your typesetting engine hints or commands about where to split up your long document into fairly-independent chunks? What if you designed your document specifically to be typeset in independent, parallel pieces so that you could guarantee that you would get the same result for section B whether or not you were typesetting the whole book at the same time? What if the typesetting system automated the stitching-back-together process of the chunks, gathering page reference info from each chunk to inform the next iteration of typesetting the other chunks? Has anyone been working on this already? It seems like it must have been discussed, but I don't know where to go to look for that discussion.

It takes us anywhere from 80 minutes on our fastest machine, to 9 hours on our slowest laptop. You should not need an average of 8 runs unless your document is ridiculously complex and I am curious what you are doing (but that is a different issue from what you are asking). So the question comes up, can TeX runs take advantage of parallelized or distributed processing? No. For the most part, this is because of another requisite: for applications to make good use of threads, they have to deal with a problem that can be parallelized well. And generally speaking, typesetting does not fall in this category. A seemingly small change on page 4 can easily affect each and every page right to the end of the document. Thank you for your response. Certainly this is true in general and in the worst case, as things stand currently. But I don't think it has to be that way. The following could greatly mitigate that problem: - You could design your document *specifically* to make the parts independent, so that the true and authoritative way to typeset them is to typeset the parts independently. (You can do this part now without modifying TeX at all... you just have the various sections' .tex files input common headers / macro defs.) Then, by definition, a change in one section cannot affect another section (except for page numbers, and possibly left/right pages, q.v. below). - Most large works are divisible into chunks separated by page breaks and possibly page breaks that force a recto. This greatly limits the effects that any section can have on another. The division (chunking) of the whole document into fairly-separate parts could either be done manually, or if there are clear page breaks, automatically. - The remaining problem, as you noted, is how to fix page references from one section to another. Currently, TeX resolves forward references by doing a second (or third, ...) pass, which uses page information from the previous pass. The same technique could be used for resolving inter-chunk references and determining on what page each chunk should start. After one pass on of the independent chunks (ideally performed simultaneously by separate processing nodes), page information is sent from each node to a coordinator process. E.g. the node that processed section two tells the coordinator that chapter 11 starts 37 pages after the beginning of section two. The coordinator knows in what sequence the chunks are to be concatenated, thanks to a config file. It uses this information together with info from each of the nodes to build a table of what page each chunk should start on, and a table giving the absolute page number of each page reference. If pagination has changed, or is new, this info is sent back to the various nodes for another round of processing. If this distributed method of typesetting a document takes 1 additional iteration compared to doing it in series, but you get to split the document into say 5 roughly equal parts, you could presumably get the job done a lot quicker in spite of the extra iteration. This is a crude description but hopefully the idea is clear enough. parallel pieces so that you could guarantee that you would get the same result for section B whether or not you were typesetting the whole book at the same time? if you are willing to promiss yourself that all chapters will be exactly 20 pages - no more, no less - they you can split the work off into separate job files yourself and take advantage of a whole server farm. If you can't ... Yes, the splitting can be done manually now, and when the pain point gets high enough, we do some manual separate TeX runs. However, I'm thinking that for large works, there is enough gain to be had that it would be worth systematizing the splitting process and especially the recombining process, since the later is more error-prone. I think people would do it a lot more if there were automation support for it. I know we would. But then, maybe our situation of having a large book with dual columns and multipage tables is not common enough in the TeX world. Maybe others who are typesetting similar books just use commercial WYSIWYG typesetting tools, as we did in the previous edition of this book.

OK, we will look into this. I'm sure Jelle knows about this but I'm a

we're scaling fonts an unnecessary number of times.
For example, we have the following macro, which we use thousands of
times:
\def\LN#1{{\switchtobodyfont[SansB,\LNfontsize]{#1}}}
indeed this will define the scaled ones again and again (whole sets of
them since you use a complete switch); internall tex reuses them but it

Would it help much to instead use
\definefont[SansBLN][... at \LNfontsize]
and then
\def\LN#1{{\SansBLN{#1}}}
?
indeed:
\definefont[SansBLN][... at \LNfontsize]
but no extra { } needed:
\def\LN#1{{\SansBLN#1}}
Thanks, we will try this.
(Jelle, since you have worked with this a lot longer than I have, please
stop me if you have concerns about my making this sort of change.)
- use unique mpgraphic when possible
I would be interested to know if this is possible in our situation. Most
of our mpgraphics are due to wanting thick-and-thin or single-and-double
borders on tables, which are not natively supported by the ConTeXt table
model.
i sent jelle the patched files
OK, I'll look to hear from him. Are these patches to support these kinds
of borders on tables, thus no longer needing to use MPgraphics?
The advice I received said to define each mpgraphic using
\startuseMPgraphic (we have about 18 of these), associate them with
overlays using \defineoverlay (again, we have 18), and then use them in
table cells using statements like
\setupTABLE[c][first][background={LRtb}]
Empirically, this seems to end up using one mpgraphic per table cell,
hence our thousands of mpgraphics. I don't know why a new mpgraphic
would be created for each cell. Can someone suggest a way to avoid this?

number of mpgraphics from 7000 to 800!

not need to use mpgraphics anyway thanks to your patches, I'll hold off
on debugging the result.
i changes the definitions a bit and now get 5 pages per second on my
laptop in luatex; xetex processes the pages a bit faster but spends way
more time on the mp part
My last run gave about 0.25 pages per second on our fastest server, when
taking into account multiple passes; that comes out to about 2 pps for
--once.
the patched files do 5-10 pps on my laptop (was 1 sec pp) so an
improvement factor of at least 5 is possible
there are probably other optimizations possible but i cannot spent too
much time on it
Thanks for all your help thus far.

But again, if you can break down the document into chunks that are fairly independent of each other (and you almost always can for large texts), this problem seems no worse for distributed processing than for sequential processing. For example, the difficult part of laying out figures in Section 1 is confined to Section 1; it does not particularly interact with Section 2. References in Section 2 to Section 1 figures are going to be relatively distant from those figures regardless of page breaking decisions. Thus the difficult problem of page breaking is reduced to the sequential-processing case... still a hard problem, but one that can be attacked in chunks. Indeed, the greater amount of CPU time per page that is made available through distributed processing may mean that the algorithms can do a better job of page breaking than through sequential processing.

Re: [NTG-context] distributed / parallel TeX?
Thanks, everybody, for the discussion on running TeX distributed / in parallel. I am much educated about the state of the art. :-) Summary ... - There is plenty of optimization that normally can be done. If a ConTeXt run is taking a really long time, chances are that something is not being done according to the design. - For most (current) purposes, documents are small enough and ConTeXt is fast enough that the effort to automate distribution of typesetting runs may not be worthwhile. On the other hand, the usage of TeX might expand if greater throughput were available. - However, as things stand now, one can always divide documents up by hand, typeset the parts independently, and stitch them back together using tools such as divert/undivert. One can even design a document with the spec that the canonical typesetting process is to typeset the sections independently; then the sections can never affect each other, except for explicitly added inter-section effects like page reference updates.

[NTG-context] starting headings at top of column
Hello, I've started talking to people in charge about contributing some money to this mailing list, or the wiki, or something ... we're certainly getting a lot of help from it. Is there an org or project to contribute to? Anyway, my current challenge is this. We have a two-column layout using columnsets. Fairly often, we start a new section (within a column... this does not interrupt the flow of columns). Some constraints we want to fulfill are: - Normally we want a little space before each new section heading - Except at the top of a column; can I check whether we're at the top of a column and do a conditional \vskip based on that?(*) - Avoid orphans: when starting a new section, if there's not enough room left in the current column, do a column break before outputting the section heading. I've tried \testcolumn[n], but it doesn't seem to work right. What are the units of the argument to \testcolumn? We also do manual column balancing using \definecolumnset, \setupcolumnset, and \setupcolumnsetlines. My concern is, does this apply after other layout is performed, so that any test performed above (*) regarding position within the column would fail to reflect these column balancing adjustments and therefore could give wrong results? That could explain why \testcolumn has been behaving in unexpected ways...

The advice I received said to define each mpgraphic using
\startuseMPgraphic (we have about 18 of these), associate them with
overlays using \defineoverlay (again, we have 18), and then use them in
table cells using statements like
\setupTABLE[c][first][background={LRtb}]
Empirically, this seems to end up using one mpgraphic per table cell,
hence our thousands of mpgraphics. I don't know why a new mpgraphic
would be created for each cell. Can someone suggest a way to avoid this?

Great...
I converted our useMPgraphics to uniqueMPgraphics. This reduced our
number of mpgraphics from 7000 to 800!
Unfortunately the result doesn't look quite right... but since we may
not need to use mpgraphics anyway thanks to your patches, I'll hold off
on debugging the result.
When I use uniqueMPgraphics, things run faster, but I get errors and

Basically, when we run with uniqueMPgraphic instead of useMPgraphic, we
get a lot fewer mpgraphic files; but the tables we produce lack the
outer border. And we get the above errors.
Googling the errors leads us to dvipdfmx, e.g.
http://tug.org/texlive/devsrc/Build/source/texk/dvipdfmx/src/spc_pdfm.c
http://dvipdfmx.sourcearchive.com/documentation/1:20050831-5/pdfximage_8c-source.html
But I don't think dvipdfmx is the cause.
Can anyone explain the error messages or suggest a fix?
We would love to use uniqueMPgraphics for efficiency, but we can't if it
gives the wrong result...
Thanks,
Lars

[NTG-context] tool for reviewing hyphenation
Hello,
We have a situation where hyphenation is an issue, due to a 2-column
layout where the columns are not very wide. We've done a lot of tweaking
of settings for hyphenation and interword spacing, and the result seems
pretty good. In particular, there are not many cases of consecutive
lines that end with hyphens, and not many cases where a hyphenation
occurs over a right-hand page break. The few cases that exist, we have
been fixing manually by using \hbox{...} to prevent hyphenation at the
trouble spot.
But the hyphenation is by nature somewhat volatile, so whenever we
change something we would like to be able to easily recheck the hyphenation.
And our book is over 1200 pages, so it would be very helpful to have
tools to make the checking more efficient.
One tool we found was the evince PDF viewer in Linux, which highlights
all search results at once. So you can search for -, and it will
highlight all hyphens, which makes it easier to scan the PDF visually
for hyphenation problems.
Still, this approach has its limitations... our layout domain experts
don't have Linux machines, and I haven't found a PDF viewer for Windows
that can highlight all search results at once.
Another approach we wondered about was having TeX highlight the
hyphenations... e.g. changed the background color to yellow or red, when
outputting a word that's dynamically broken/hyphenated. (Rather like we
have TeX output red grid lines to help with debugging layout.)
I think we would also want to highlight static hyphens that occur at the
end of a line, as in Niger-
Congo, because they have a similar visual impact. Possibly using a
different color.
This would be an ideal solution, I think, but we don't know how to have
TeX detect when a word gets dynamically hyphenated.
Another possibility we've looked into is using javascript in Adobe
Reader to find and highlight end-of-line (and end-of-page) hyphens. But
this approach has proved more difficult than expected... the API and the
DOM are complex, and I haven't figured out yet how to access the text of
the document to search for hyphens. (The search method seems to just
go to the first or next occurence, and highlight only one occurrence at
a time.)
Thanks for any help,
Lars

[NTG-context] ConTeXt standalone - in what situations is it better?
Hello, I was looking into simplefonts (http://wiki.contextgarden.net/simplefonts) and noticed the clause if you’re running ConTeXt Standalone http://wiki.contextgarden.net/ConTeXt_Standalone (which is a better option) Well I'm using TeXLive, but am happy to take good advice, so I looked at http://wiki.contextgarden.net/ConTeXt_Standalone to see why it would be a better option. The basic reason I can see is that Standalone is updated more frequently. So if you're using bleeding-edge features of ConTeXt (including recent fixes to simplefonts?), I can see wanting to use Standalone and have access to the latest features and fixes. On the other hand, if you're working on a large production project that has to be careful of stability, is there any advantage to Standalone over TeXLive? Sure, you can keep a standalone version frozen in place, but then that seems equivalent to staying with an existing version of TeXLive. The other issue for me with Standalone is that the only version listed for Windows is W32TeX. When I go to the web page for that platform, I don't see any information about what W32TeX is; just how to install it. It sounds like it's specific to 32-bit systems, and mine is 64-bit. But I suppose in that regard it's no different from TeXLive -- the executables are 32-bit but they run fine on 64-bit systems. Does anybody have advice for me on other reasons for switching from TeXLive to ConTeXt Standalone, or reasons not to?

You would need the ConTeXt distribution for that, TeX Live 2013 is too
old. (You can probably still load the simplefonts module explicitly or
write the typescripts yourself - again different syntax.)
Mojca
Thanks again for your responses.
I did try loading the simplefonts module explicitly, but
definefontfamily is still undefined.
I'm working on a large, production project, and the deadline is too
close to risk using unstable releases. Is there a context release since
Wolfgang's new version of simplefonts, that has been declared stable?
Given that his new version came out less than a month ago, it seems
unlikely.
Maybe I can get TTFs working using mtxrun, as Hans suggested. It seems
to be working on Windows; I need to try the same on Linux with our
custom font.

After installing the gentium-tug package (sudo /usr/local/bin/tlmgr install gentium-tug), and compiling a .tex file using \setmainfont[Gentium], the errors went away, and my names.tma now includes several variants of Gentium. At no point did I run mtxrun (knowingly). On the other hand, on Windows, I had installed TeX Live context scheme as well, and have not installed gentium-tug. But I did install Gentium as an OS font (using TTF files). I then ran mtxrun --generate (as suggested by Hans), and after that, gentium* showed up in names.tma, and I was then able to successfully compile a .tex file using \setmainfont[Gentium] with mkiv context. (But that didn't work before I ran mtxrun --generate.) Just a couple of data points in case they're relevant.

[NTG-context] setting size for mainfont or sansfont in stable simplefonts
Hello,
I'm using the simplefonts module from TeX Live 2013. (I can't use the
new simplefonts for this production project, due to stability requirements.)
I have the following, which works well for the most part:
\setupbodyfontenvironment[default][em=italic]
\usemodule[simplefonts][size=9.2pt]
\setmainfont[Gentium Book Basic]
\setsansfont[Tex Gyre Heros]
\starttext
Serif typeface: regular, {\em italic}, {\bf bold} and {\bf\em bold
italic} styles.
\ss Sans--serif typeface: regular, {\em italic}, {\bf bold} and {\bf\em
bold italic} styles.
\stoptext
Because the Tex Gyre Heros font is larger than Gentium Book Basic at a
given point size, when I compile this document, there is a size mismatch
between the serif and the sans typefaces. So I looked for a way to give
the sans font a smaller default size. I couldn't find an example of such
at http://wiki.contextgarden.net/simplefonts. I tried this:
\setsansfont[Tex Gyre Heros][size=8pt]
but it didn't seem to have any effect.
Is there a way to do what I'm trying to do? I could use
\switchtobodyfont[8pt] every time I go to sans, but I don't think that's
the intention of simplefonts.
Thanks,
Lars

[NTG-context] how to include sans, bold and size in \setuptab[headstyle=???]
Hello, I have the following MWE:
\starttext
\setuptab[headstyle=ssbfb]
\tab{foo} \input knuth \par
\stoptext
Here, the headstyle specifies a sans font with boldface style, at 1.44
times the current bodyfont size.
However, I want to be able to specify an absolute point size, instead of
a relative size.
I tried variations like
\setuptab[headstyle=18pt]
but that has no effect: the size remains 12pt, or whatever the default is.
If I use
\setuptab[headstyle={\switchtobodyfont[18pt]}]
then the size takes effect (for the key only, which is what I want).
I can combine that with sans:
\setuptab[headstyle={\switchtobodyfont[ss, 18pt]}]
and that works.
But how to mix in boldface?
\setuptab[headstyle={\switchtobodyfont[ssbf, 18pt]}]
doesn't give sans boldface, but reverts to a serif, non-bold style (at
18pt size).
\setuptab[headstyle={\switchtobodyfont[ss, bf, 18pt]}]
gives the same results.
I finally tried
\setuptab[headstyle={\ssbf \switchtobodyfont[18pt]}]
and that works! But it seems clunky: it looks like it requires two font
switches, which I'm told makes things slower.
And I can't help wondering if I'm missing some simpler way.
Is there a more efficient or elegant way to do this?
Thanks,
Lars

\definefont[BigBoldSans][SansBold at 18pt]
\setuptab[headstyle=BigBoldSans]
OK, but in order to use this systematically, I would have to have a
\definefont for every potential combination of font style (serif/sans),
alternative (bold/italic/etc.), and size that will get used in the
document. In a large, complex book, that extra layer of indirection
seems unattractive. But maybe there's no better way to do it.

[NTG-context] syntax for \definesimplefont in TeX Live version of simplefonts
Hello, We are using simplefonts, the version included with TeX Live 2013. As mentioned in another email, we don't have the freedom to experiment with potentially unstable versions. I've been reading http://wiki.contextgarden.net/simplefonts and have it working well so far with the mainfont, sansfont, and mainfontfallback. The part I need help with is for using another font. http://wiki.contextgarden.net/simplefonts#Defining_other_typefaces_and_fonts says we can use * |\definesimplefont|, defines a font for the use in headers or other style elements. * |\simplefont|, defines a font for inline use. Can anyone tell me the syntax for these commands - and for using them? I tried \definesimplefont[titleface][Gentium Basic] ... \setupbodyfont[titleface] There are no complaints and the \definesimplefont line, but I don't know if it's the right syntax. And the \setupbodyfont line is giving the warning fonts typescripts unknown library 'titleface' So I'm guessing that the \definesimplefont line is correct, but I just don't know how to use the defined font.

The \definesimplefont command can be used when you want a certain font
for the chapter, section etc. heading, e.g.
\definesimplefont[ChapterFont][Gentium Basic][size=24pt]
\setuphead[chapter][style=ChapterFont]
but I don’t recommend this command anymore (and removed it from the new
version)
because you can get the same result with a custom typeface, e.g.
\definesimplefonttypeface[chapterfont][Gentium Basic]
\definefont[ChapterFont][\classfont{chapterfont}{Serif} at 24pt]
\setuphead[chapter][style=ChapterFont]
When you want to change only the global font for your document you
need the \definesimplefonttypeface command, e.g.
\definesimplefonttypeface[documentfont][Gentium Basic]
\setupbodyfont[documentfont]

Thanks, very helpful.

[NTG-context] simplefonts: defining a fallback for a non-main font
Hi again,
I'm using simplefonts (TeX Live 2013 version) and I have a main font:
\setmainfont[Gentium Book Basic]
and I can set a fallback for it,
\setmainfontfallback[Gentium Plus][range={ipaextensions}, force=yes,
rscale=auto]
and that works.
But then I have another font for the title:
\definesimplefont[titleface][Gentium Basic][size=40pt]
How do I set a fallback for it?
After looking at the source code for simplefonts, I tried:
% undefined cs: \definesimplefontfallback[titleface][Gentium
Plus][range={ipaextensions}, force=yes, rscale=auto]
% undefined cs: \fontfallback[titleface][Gentium
Plus][range={ipaextensions}, force=yes, rscale=auto]
% undefined cs: \definefallbackfont[titleface][Gentium
Plus][range={ipaextensions}, force=yes, rscale=auto]
But they all gave undefined control sequence errors.
I can work around the problem by setting the main font before the title,
using the main font for the title, and then changing the main font after
the title is done. But that seems kludgy.
Thanks,
Lars

There is no support for this with the old version of the module.
For posterity, here is how I worked around it:
\usemodule[simplefonts]
% The main font for text:
\setmainfont[Gentium Book Basic]
\setmainfontfallback[Gentium Plus][range={ipaextensions}, force=yes,
rscale=auto]
% The font for the title:
\def\titlefont{Gentium Basic}
\starttext
% Temporarily change the main font, while keeping the main font fallback:
{ \setmainfont[\titlefont] \switchtobodyfont[40pt] Title with a fancy
ɠlyph }
% Back to our previously defined main font:
Body text ...
\stoptext

Otherwise, the interline space will not be calculated correctly.

[NTG-context] how to reduce \lineskiplimit in ConTeXt grid layout
As you know, in plain TeX, \lineskiplimit tunes the vertical glue algorithm by specifying the minimum amount of space between the bottom edge of one line and the top edge of the following line. But in ConTeXt, it appears that \lineskiplimit is set to zero, at least in grid mode. We're using grid mode, and we have some occasional high ascenders, e.g. capital letters with diacritics on top. We have bodyfont size 8.1pt, and interlinespace = 9.3pt. We realize this is less than the recommended ratio of 1.2. Understandably, when those tall characters occur, we sometimes get a blank line above them. It looks like the \lineskiplimit would be violated if the 9.3pt interlinespace were enforced, so ConTeXt adds some space (analogous to \lineskip in TeX?). But since we're on a grid, more space has to be added in order to conform to the grid. All that makes sense, but we would like to be able typeset the lines closer together, and judge for ourselves whether it looks too bad. (When we used to typeset the same text at 8.1pt/9.3pt using mkii, blank lines did not occur.) Is there something similar to \lineskiplimit that we can tweak? I've been reading section 5.5 Line Spacing in the context ref manual, but I don't see anything there about changing a threshold analogous to \lineskiplimit. I tried setting \lineskiplimit=-2pt, but that caused a worse problem: a blank line across both columns, instead of just one.
